Microsoft support for classic ASP and VB6

Q: Do you know the date when Microsoft will end support for classic Asp and VB6?

A: Primary support ended in April of 2005 for those products. They are currently in the "extended support lifecycle" which means that we only provide free security fixes. That will be ending next year in April and then there will only be the "online" support of KB articles that are already published.

If you have a customer still using them, I highly recommend you upgrade them, as that technology just isn't up to the task of dealing with Today's types of security, scalability or reliability requirements.

Thanks to Bill Steele (Microsoft) for providing this info first hand.

Overseas Outsourcing

I came across an article from Computer World that looks at Overseas outsourcing in a different light. Typically the argument has been cost vs. quality, but in this article many are saying outsourcing is becoming a necesary evil due to lack of resources in the western hemisphere. A shortage of IT graduates from Western universities is leading companies to call on developing countries to meet research demand, Microsoft Chairman Bill Gates said today.

DoEvents()

Q: I have a For-Next loop where intensive processing takes place. I would like the application to respond other events during execution of this code.

A: The method DoEvents() will handle this requirement. By placing a call to DoEvents at the top of the loop, this method will process all messages queued from the Operating System, including shutting down the application. Using the DoEvents() method requires a reference to System.Windows.Forms.dll. Furthermore, the DoEvents() method is found in the class System.Windows.Forms.Application.

Private Sub btn1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btn1.Click

FAQ about the latest IE bug

Listed below are a set of FAQ questions surrounding the new IE bug.

What's the problem? A vulnerability newly discovered in Microsoft Internet Explorer could allow an attacker to take over a targeted machine -- even a machine whose patches are all up to date.

What's it called? The Common Vulnerabilities and Exposures list tentatively designates this vulnerability as CVE-2006-4868. McAfee calls it Exploit-VMLFill; Trend Micro calls it EXPL_EXECOD.A; Symantec calls it Trojan.Vimalov, reflecting its probable Russian origin. SecurityFocus assigns it a Bugtraq ID of 20096.

Which programs and versions are affected? Internet Security Systems reports that the flaw affects all versions of IE that include support for VML, which means Versions 5 and 6, though tests so far have generally looked at Version 6. There have been no reports of the attack working on IE 7. Recent versions of Outlook and Outlook Express are also vulnerable, as are all versions and service packs for Windows 2000 and X…

Q: I was wondering if document libraries in SharePoint 2007 support folders within them. Does MOSS 2007 support folders?

A: Yes, MOSS (Microsoft Office SharePoint Server) does support folders within a document library (see screen caption below). To create a folder, simply click "New" and select "New Folder".

ODC vs. BDC

As discussed during our last meeting, SharePoint 2007 has many new features. And as with any new feature, some confusion is bound to be included. Two of those new features are ODC and BDC. To help clear some of the confusion around these 2 items, here's a brief explanation of the two.

ODC (Office Data Connection) is used to connect Excel Services to a specific database, without making the user remember userID, password, DB Name, server name, etc. Instead, all these items are stored in an XML format file with the extension name .ODC. The .ODC file can be created by using the Excel client to create the file, then upload the file to a Data Connection Library. Once uploaded, a user simply refers to the ODC file, where all connection string parameters are stored. The data connection can then be used by various Excel Web Parts to display the data and KPIs. To read more about the ODC, go to http://blogs.msdn.com/excel/archive/2006/02/16/533865.aspx

What is WinFX?

Q: What is WinFX?

A: WinFX is an Object Oriented set of APIs that leverage the .Net Framework and expose that breadth of the Longhorn OS to developers. WinFX contains .Net Framework(FW) and is available in managed code. It builds on and extends the .Net FW

As the name may suggest, WinFX consists of 2 major parts:
1. WIN (Windows): Win32 APIs.
2. FX (Framework): speaks to .Net Framework

There are 4 Portions of WinFX
1. Presentation
2. Data
3. Communications
4. Fundamentals


In addition, WinFX offers functionality from other systems:
Avalon fucntionality is in the System.Windows namespace. This is the new presentation SubSystem for Longhorn.ASP.Net and Indigo functionality are both in the System.Web namespace. Indigo is the new technology for web services.WinFS functionality is in the System.Storage namespace. It contains relational aspects of the file system.Yukon Functionality for database access is in System.Data.SQL Server namespace

Difference between XHTML and DHTML

Q: What is the difference between XHTML and DHTML?

A: XHTML is a more structured version of HTML, which
sits nicely with the XML structure. XML (eXtensible Markup Language) is used to identify the data contents (i.e. name, address, phone, etc.) XML can then be used with XSLT to render the contents in different ways. Couple XML with HTML and you have a XHTML.

DHTML (Dynamic Hypertext Markup Language) is a Microsoft derived term. It is a combination of HTML, CSS, and JavaScript. It all works via the DOM (Document Object
Model). This is a method of referencing objects within a document so that
you can manipulate them through JavaScript.

Microsoft Patches Contain Memory Bugs

Earlier this month, Microsoft released 12 patches for fixing 23 vulnerabilities. Of those 12 patches, MS06-040 and MS06-042 were discovered to have memory bugs causing programs to crash.

MS06-040 affects programs that use very large chunks of memory on some versions of Windows. According to Microsoft, programs such as Microsoft Navision 3.7, which require allocations of more than 1GB of memory, can crash after the update is installed.
Most Windows systems do not experience the bug, but Microsoft Windows Server 2003 and the 64-bit version of Windows XP Professional Edition are affected. Microsoft's hotfix for this problem can be downloaded from their site.

More troublesome has been the MS06-042 update for Internet Explorer, which has caused browser crashes while using Web-based applications such as PeopleSoft, Siebel and Unicenter. Microsoft issued a hotfix for this update earlier in the week and is promising to reissue the buggy update next Tuesday. For more information on this b…

What is "Atlas"?

Q: What is "Atlas"?

A: "Atlas" is the code name for a set of ASP.Net technologies used to add Ajax (Asynchronous JavaScript And XML) support to ASP.NET. It consists of a client-side script framework, server controls, and more. In other words, Atlas is Microsoft's implementation of Ajax.

This new Web development technology from Microsoft integrates client script libraries with the ASP.NET 2.0 server-based development framework. In addition, "Atlas" offers you the same type of development platform for client-based Web pages that ASP.NET offers for server-based pages. And because "Atlas" is an extension of ASP.NET, it is fully integrated with server-based services. "Atlas" makes it possible to easily take advantage of AJAX techniques on the Web and enables you to create ASP.NET pages with a rich, responsive UI and server communication. However, "Atlas" isn’t just for ASP.NET. You can take advantage of the rich client framewo…

Using SPUserUtil to synchronize SharePoint user Display Names, E-mail addresses with Active Directory

I found an article on keith Ritchie's blog detailing how to use SPUserUtil to synchronize SharePoint user Display Names and Email addresses with the information in Active Directory

SPUserUtil will mean either WSSUserUtil or SPSUserUtil respectively (WSSUserUtil is used to administer Windows SharePoint Sites on a standalone WSS Farm/Virtual server OR Windows SharePoint sites in the same virtual server of a SharePoint Portal Server 2003 site.) SPSUserUtil is a superset of WSSUserUtil, designed for working on SharePoint Portal Server Areas.

Detecting Mobile Browsers

As discussed in our last meeting, web applications can be built to handle both PC browsers and mobile browsers. To do so, the application needs to detect if the browser is a mobile device and redirect the application to a page designed to display UI adequate for the smaller mobile browser. Detecting the browser is done using the following code sample, and it's typically placed in the Page_Load() of the login.aspx or default.aspx


Private Sub Page_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Try
If Not IsPostBack Then
If Request.Browser.IsMobileDevice = True Then
Response.Redirect("mobile/login.aspx")
End If
End If

Catch ex As Exception
ProcessEx(ex)
End Try

A: The USPS offers several free web services that perform these functions. Go to http://zip4.usps.com/zip4/welcome.jsp and click on "web tools" in the lower left corner.

Web Part Compatibility

When web parts first came out with SharePoint 2001, there wasn't much of an issue with compatibility. However, now with SharePoint 2003 out for several years, ASP.Net 2.0 supporting web parts, and soon SharePoint 2007 will be released, one has to consider version compatibility among these versions. Listed below are some facts to help decipher any compatibility issues.


Using Son of SmartPart will allow you to run ASP.NET 2.0 UserControls and WebParts in SharePoint 2003.SharePoint 2003 web parts will not work in ASP.NET 2.0 pages with Web Part Zones.SharePoint 2003 web parts will work in SharePoint 2007.In addition, take time to review Dino Esposito's article "WebParts: From Sharepoint to ASP.NET 2.0".

SharePoint 2003 Limitations using WMSDE

Q: I want to use WMSDE for a very limited POC (proof of Concept) of SPS 2003. Other than Search and performance, are there any other things to be concerned about?

A: If SPS 2003 is not installed WSS uses a special version of MSDE, known as SQL Server 2000 Desktop Engine (Windows), or WMSDE. This is an unthrottled version of MSDE designed only to be used by Windows components, and as such is not limited in the same way as MSDE. The maximum size limit and current connections limit have both been removed. However it is still much more limited than SQL Server 2000 in the following ways:WMSDE does not include enterprise management tools such as those provided with SQL Server 2000 (e.g. SQL Enterprise Manager MMC tool) for backing up and restoring the database. However command line tools can still be used (e.g. stsadm tool). WMSDE can only be managed locally – you cannot remotely connect. WMSDE does not support full-text search – so search from within team sites is not possible. You cannot d…

Windows Fundamentals

Microsoft Corp. released a new version of its operating system for businesses this week that extends the life of older PCs by effectively turning them into thin-client computers. Called "Windows Fundamentals" for Legacy PCs, the software is offered only to customers on Microsoft's Software Assurance licensing and maintenance program.

It is not a full-featured operating system, but it improves the security and manageability of PCs for customers with systems that are too old for Windows XP and who aren't ready to upgrade their hardware, Microsoft said.

Can 32-Bit Applications run on Windows 2003 64-Bit?

Q: Can I run SQL Server 2000 32 bit on Windows 2003 64 bit?

A: The short answer is yes. WOW64 (Windows on Windows 64) is a compatibility environment provided by the operating system that allows a 32-bit application to run on a Windows 64-bit operating system. For more information, see 64–Bit Windows Part 11: Windows on Windows 64.

For web applications, Windows Server 2003 SP1 enables WOW64 compatibility for 32–bit Web applications in IIS 6.0. Based on the value of a metabase property, IIS will either start a 32–bit or a 64–bit worker process. In other words, IIS 6.0 can run applications in WOW64 or native 64–bit, but not both. For more information, see Windows Server 2003 SP1 enables WOW64 compatibility for 32-bit Web applications in IIS 6.0.

Next Versions of VS and SQL Server

Orcas: code name for the next version of Visual Studio, due in 2007 or 2008. One of the big
features of the new VS is Language-Integrated Query (LINQ). LINQ is a breakthrough technology that eliminates the impedance mismatch among different data domains. With LINQ, developers do not need to learn separate query syntaxes when querying over diverse data domains such as XML, Relational and Objects. LINQ has been very well received both last year at its announcement at the PDC, and more recently at Tech-Ed in Boston. Orcas, the next version of Visual Studio, includes LINQ infrastructure that enables this powerful combination of languages and API’s, as well as concrete support in multiple programming languages and data domains.

Orcas is based on the .Net Framework 3.0, which is comprised of the existing .NET Framework 2.0 components, including ASP.NET, WinForms, ADO.NET, CLR, and additional base class libraries. It will also include Windows Presentation Foundation (WPF), Windows Communicatio…

Passing values to JavaScript

Q: I have an ASP.Net application where I would like to pass the value of a variable to JavaScript code on the same page. How can I do that?

A: An article found at http://aspalliance.com/ArticleViewer.aspx?aid=851&pid=-1 explains exactly how to do that. First, place the script in a separate .js file. Then pass the required value to the script using Page.ClientScript.RegisterClientScriptBlock().

In ASP.Net 2.0 Page.ClientScript.RegisterClientScriptBlock() is used to download and store a script in a browser's cache for quicker reponse in the browser.

Another similar method is Page.ClientScript.RegisterStartupScript(). This method is best used when you have a JavaScript function that you want to initiate when the page is loaded. The code, including this method call, would be placed in the Page_Load() event handler.

Importing Mutliple Web Parts Simultaneously

During the last SIG meeting, one of the members asked if multiple web parts could be deployed simultaneously. There was no obvious way to use the SharePoint UI to import multiple web parts at once. However, other solutions are available by use of STSADM.EXE and InstallAssemblies.EXE.

STSADM.EXE
To use the Stsadm.exe command to deploy a Web Part package on a server computer running Windows SharePoint Services, open a command prompt, and then type the following command:

stsadm.exe -o addwppack -filename Web_Part_Pack_name [-url URL] [-globalinstall] [-force]

A series of these commands can be entered into a batch file and used to import multiple web parts simultaneously.

STSADM.EXE is a standard SharePoint utility, and is installed by default on the SharePoint server.


InstallAssemblies
InstallAssemblies is an assembly installation tool for Windows SharePoint Services. The tool is designed for use within development and testing environments. By default, InstallAssemblies will start in interactiv…

Retrieving Identity Values

Q: How do you retrieve the Identity value of a row that was last inserted in a SQL Server DB?

A: SCOPE_IDENTITY, IDENT_CURRENT, and @@IDENTITY can all be used to return values inserted into IDENTITY columns. However, each one has its own scope limitations. Scope refers to a specific module (i.e. a stored procedure, trigger, function, batch).

SCOPE_IDENTITY will return last identity values generated in any table in the current session, but within the current scope.
IDENT_CURRENT returns the value generated for a specific table in any session and any scope. It is not limited by scope and session, but it is limited to a specified table.
@@IDENTITY will return the last IDENTITY column value inserted across any scope in the current session, but it is not limited to a specific scope. For more information, see http://msdn.microsoft.com/library/default.asp?url=/library/en-us/tsqlref/ts_sa-ses_6n8p.asp

Web Part Debugging Tip

Here's a little tip on SharePoint that I wanted to share with everyone. When debugging a web part on a SharePooint site and there are problems bringing up the page, try the following. Manually enter the URL of the page in question and add "?contents=1" to the end of the URL. Once you press enter, the page returned is the "Manage Web Part Page".

This will list all web parts on that page, including their title, type, display on page, and personalized properties. This will help identify if other web parts on the page are causing problems with opening the page.

File Access in VB.Net

Listed below is an example of file access in VB.Net, utilizing many of the I/O functions. First the routine creates a file, then deletes it. This routine is used only for demonstration purposes.

Sub FilePurge()

Static dtLastPurgeTime As DateTime
Dim dtNow As DateTime
Dim intCounter As Integer
Dim Files() As String
Dim strGUID As String, strTXTName As String

While True
strGUID = System.Guid.NewGuid.ToString
strTXTName = "C:\Temp\STB_" & strGUID & ".TXT"

'Create a uniquely named .TXT file
Dim swTXT As StreamWriter
swTXT = File.AppendText(strTXTName)
swTXT.WriteLine(strGUID)
swTXT.Close()

'Wait 2 seconds before proceeding
System.Threading.Thread.Sleep(2000)

dtNow = Now
Dim lTimeDiff As Long = DateDiff(DateInterval.Hour, dtLastPurgeTime, dtNow)

If lTimeDiff > 24 And Now.Hour = 22 Then 'Check if last purge was more then 24 hours ago and current hour is 10PM

'Purge *.TXT files
Files = Directory.GetFiles("C:\Temp", "STB_*.TXT")

Upcoming .Net related events

Listed below are upcoming events in the Cleveland area pertaining to .Net development:
June 8th: ONSQL SIG MeetingJune 10th: GCPCUG General MeetingJune 22nd: MSDN EventJune 27th: C#/VB.Net SIGIf you have any questions about these events, please e-mail me at sam@clevelanddotnet.info.

The LINQ Project & SQL Prompt

Microsoft has begun work on the next version of .Net. One of the key features is integrated SQL commands. T-SQL keywords and commands will now be part of intellisense, elimating spelling errors. In addition, table and field names will also be incorporated in intellisense. This project is named LINQ (Language Integrated Query). To read more about LINQ, please visit The LINQ Project.

For those that can't wait for the next release of .Net to use this feature, Red Gate Software has introduced SQL Prompt. This product provides SQL Intellisense in Microsoft Query Analyzer, SQL Server 2005 Management Studio, Visual Studio 2005, Visual Studio .NET 2003, SQL Server 2000 Enterprise Manager, and UltraEdit32. To read more about this product or to download a free version, please visit the SQL Prompt web site.

Detecting a user's group in SharePoint 2003

Listed below is a C# example of programmatically querying the group(s) a user belongs to on a SharePoint 2003 site:

using Microsoft.SharePoint;
using Microsoft.SharePoint.WebControls;

private boolean IsContributor()
{
boolean bContributor = false;
SPWeb currentWeb = SPControl.GetContextWeb(this.Context);
SPRoleCollection currentRoles = currentWeb.CurrentUser.Roles;

foreach(SPRole myRole in currentRoles)
{
strRoles = myRole.Name.ToString();

if (strRoles == "Contributor")
{
bContributor = true;
break;
}
}

return bContributor;

}

"File or assembly name Microsoft.VisualBasic.Compatibility, or one of its dependencies, was not found."

I had an windows application that was converted from Visual Basic 6.0 to VB.Net 2003. After it ran fine in development, I moved to production where I received the following error "File or assembly name Microsoft.VisualBasic.Compatibility, or one of its dependencies, was not found."

Since the application was converted from an older version of VB and uses some legacy functions, it requires "Microsoft.VisualBasic.Compatibility.dll". This library was originally found on the development machine in C:\WINDOWS\Microsoft.NET\Framework\v1.1.4322, but was not found on the production server.

The easiest way to resolve this is simply to copy the .DLL into the working directory of the application. The .DLL can also be packaged with the project installation to avoid the same issue from repeating with future installs.

Preventing Timeout while debugging XML Web Services

When debugging XML Web Services, an exception appears indicating the operation has timed out. To resolve this problem, set the TimeOut property on the XML web service object to -1. This will set it to infinite timeout.

This tip was found in "Debugging Applications For Microsoft .Net and Microsoft Windows"

"It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual"

Q: I have an ASP.Net application that when launched produces the following error:

It is an error to use a section registered as allowDefinition='MachineToApplication' beyond application level. This error can be caused by a virtual directory not being configured as an application in IIS.

What can I do to resolve it?

A: This could be do to the virtual directory not being configured as an application.
To create an Application using a Virtual Directory, use the following procedure.
Open the IIS Manager (inetmgr.exe)Right click on "Virtual Directory" and select "Properties".Click on the "Create" button. The Virtual Directory is now configured as an Application and the ASP.Net should work as expected. If not there maybe a conflict with the settings in the Machine.config file.

Microsoft Expression Products

Microsoft has released a new product line called Expression, targeting web designers and developers. The product line up consists of 3 products:
Expression Graphic Designer: used for creating vector or pixel-based rich graphics with texture and dimensionsExpression Interactive Designer: for creating an engaging and interactive interface using multi-media.Expression Web Designer: used for building optimal web sites using a visual designer and leveraging ASP.Net, XML, and XHTML.Web designers can incorporate elements from each product into a single web site. In addition, all these products can be used in conjunction with Visual Studio 2005 to leverage the capabilities of programming languages such as C# and VB.Net. Projects can then be built and deployed from Visual Studio.

For more information or to download a trial version, visit the Expression home page at http://www.microsoft.com/products/expression/en/default.mspx

Microsoft Expression Web Designer

Today Microsoft has released the beta version of Expression Web Designer. It is intended to replace Frontpage, which is being phased out of the product lineup.

In addition, Expression Web Designer will also offer reporting tools for web developers to help identify sites where Cascading Style Sheets are causing errors, accessibility of the site to handicapped Web users, and how many errors users of older Web browsers are encountering when viewing the site.

To download the CTP (Community Technology Preview) beta version, go to http://www.microsoft.com/products/expression/en/web_designer/wd_free_trial.aspx

Generating a GUID

Q: How can I create a unique value without using a counter?

A: The .Net framework provides a method for generating a universally unique identifier or GUID and can be accessed as shown below:

Dim strGUID as String = System.GUID.NewGuid().ToString()

GUID is short for Globaly Unique Identifier. This number is
based on IP address, MAC address, and date/time. It's represented as a series of alpha-numeric characters in the format {8-4-4-4-12}.

Using the NewGuid() method allows unique numbers to be generated by one function call, without concern for repeating identifiers or counters.

C# in SQL Server 2005 Reporting Services

Q: I know that VB.Net functions are available in SQL Server 2005 RS (Reporting Services), but does it also accept C# commands?

A: The expression language for Reporting Services is VB.Net only. You can call an assembly that contains functions written in C#. This is a very valid option, but the call from within the report will be with the VB.Net syntax.

Thanks to Mike Shelton (Microsoft) for answering this question.

MS Certification Courses

Q: Where can I take a class that would be geared toward certification in either .NET forms or ASP.Net? I interested in exams 70-315 or 70-316.

A: Check out this link (http://www.microsoft.com/learning/mcp/mcsd/requirementsdotnet.asp). It lists the tests needed for passing the MCSD along with MS courses. You can register with these exact same course numbers at CCC or CSU Continuing Education, or any other MS certified training facility.

Microsoft Downloads

I found a few interesting downloads, free from Micorsoft.

User Profile Hive Cleanup Service:The User Profile Hive Cleanup service helps to ensure user sessions are completely terminated when a user logs off. System processes and applications occasionally maintain connections to registry keys in the user profile after a user logs off. In those cases the user session is prevented from completely ending. This can result in problems when using Roaming User Profiles in a server environment or when using locked profiles as implemented through the Shared Computer Toolkit for Windows XP.http://www.microsoft.com/downloads/details.aspx?familyid=1B286E6D-8912-4E18-B570-42470E2F3582&displaylang=en

Microsoft Anti-Cross Site Scripting Library

Microsoft has recently released an Anti-Cross Site Scripting Library to help prevent cross site scripting attacks. To download the Anti-Cross Site Scripting Library, go to http://www.microsoft.com/downloads/details.aspx?familyid=9A2B9C92-7AD9-496C-9A89-AF08DE2E5982&displaylang=en

A Cross Site Scripting attack (XSS) occurs when a hacker inserts a link in an e-mail or web forum that appears to be legitimate (i.e. cnn.com, google.com). However, the link actually a malicious script code embedded in the URL. When the unsuspecting user clicks the link, the script is executed on the host web site. The script code maybe used to transfer cookies from the victim's PC to the hacker's machine. The cookies may contain user ID's, passwords, or possibly credit card information, all which can be used for illegal purposes. To read more about this security attack, visit http://msdn.microsoft.com/library/default.asp?url=/workshop/author/dhtml/httponly_cookies.asp

Error while trying to run project: unable to start debugging on the web server

Q: When I tried to debug my ASP.Net project (VS 2003), I received the error "Error while trying to run project: unable to start debugging on the web server." How do I correct this?

A: Depending on the remainder of the error message, there are different methods of resolving this error. For more detailed information on fixing this issue, go to http://support.microsoft.com/kb/306172.

What is the difference between classes and modules?

Q: What is the difference between classes and modules?

A: Visual Studio.Net stores code in either classes or modules. Classes are used for items that define their own storage and have persistent data. In addition classes must be instantiated before they're used, unless the keywords "Static" (C#) or "Shared" (VB.Net) are used.
Modules, on the other hand, can be viewed as simple code libraries where the methods can be called directly.

Site Context Search Box in SPS

Microsoft has recently made available sample code for creating a site search box in SPS (SharePoint Portal Server). Use the search box sample to customize the Windows SharePoint Services site-level Search box to return Microsoft SharePoint Portal Server Search (SharePointPSSearch) results. This download contains sample Microsoft Visual C# code for creating the custom search box and a deployment package (CAB file) for installing the sample. You can modify this sample code to fit your needs. To download the sample code, visit http://www.microsoft.com/downloads/details.aspx?familyid=DE65EB72-3BB3-4D32-98C2-F2C94458C957&displaylang=en

Bug Found in McAfee's Update Program

The McAfee update (DAT 4715) released on Friday was designed to protect computers against the W95/CTX virus. But because of a programming error, the update also incorrectly identified renamed and quarantined hundreds of legitimate executables including popular ones such as excel.exe, lsetup.exe, uninstall.exe, shutdown.exe and reg.exe.

For companies that had configured their McAfee antivirus program to automatically delete bad files, the error resulted in the loss of hundreds, and in some cases even thousands, of files on systems in which the update had been installed, said Johannes Ullrich, chief technology officer at the SANS Internet Storm Center (ISC) in Bethesda, Md.

How Microsoft sets up their own SQL Servers.

This is an interesting blog article from Microsoft.com Operations (http://blogs.technet.com/mscom/archive/2006/02/13/419406.aspx). It details how they setup their SQL Servers. It is interesting that they do not use clusters, preferring log shipping to keep multiple servers up to date, and perform "manual failover" from web sites by modifying connection strings. Also interesting is that they run SQL Servers behind Network Load Balancers.

Thanks to Mark H. for passing this article along.

Versions of Windows Vista (Europe)

On yesterday's blog (http://clevelanddotnet.blogspot.com/2006/03/versions-of-windows-vista.html), I posted a summary describing the 6 versions of Windows Vista. In addition to those 6 versions, Microsoft will be releasing 2 additional "N" versions to comply with the European Union's anti-trust rulings. Vista Home Basic and Vista Business will be both be offered as "N" versions, without a Windows Media Player.

LC.EXE

Q: What is LC.EXE?

A: LC.EXE (License Compiler) is a command line utility provided with .Net Framework 2.0. By default this utility is installed in C:\Program Files\Microsoft Visual Studio 8\SDK\v2.0\Bin. When executed, LC.exe will read license information from a text file and include it with .Net assembly. For more information, goto http://msdn2.microsoft.com/en-us/library/ha0k3c9f.aspx.

Recently a KB (Knowledge Base) article was published for a bug regading this utility. The License Compiler (Lc.exe) throws an exception when a .NET Framework 2.0 application consumes licensed components on a computer that is running a 64-bit operating system. For more information, see KB article 913961.

Using Shutdown.exe

Q: How can I remotely shutdown a machine in a workgroup?

A: Use the Shutdown.exe command with the –m switch. This command is found in the Windows System directory (i.e. C:\Windows\system32 for Win XP), and will allow you to specify a remote computer name to shutdown. See the following for more info

Detecting a ClickOnce Application

Q: How do I tell if I'm currently running in the context of a ClickOnce application?

A: You can see if a ClickOnce application is running in the current AppDomain by checking the AppDomain.CurrentDomain.ActivationContext property. If that value is non-null, then the domain is running a ClickOnce application. The ActivationContext will also get you the name of that application. There may be situations (such as choosing an isolated storage scope), where having this information is necessary and useful.

File Upload Limit

Q: I’m using code very similar to that in this article (http://www.dotnetspider.com/technology/kbpages/568.aspx). The problem I have is when I try to upload a 9 MB file, I immediately get “Page cannot be displayed” error. Execution doesn’t even reach the PageLoad() event. The size limit for an IMAGE type in SQL Server 2000 is 2GB+, so size should not be a problem here. When I try the same function for files under 4MB, everything works as expected. What's the problem?

A: Your web application can only upload a file size of 4 MB only. To upload files more than 4mb you have to add option in the web.config file and set the maximum file size there.

In addition, if you're running IIS6, you could be hitting the limit for AspMaxRequestEntityAllowed. If the Content-Length header field of the HTTP request is larger than this limit, the page will bomb out immediately. You can increase the value in IIS6's metabase. For more info, goto
http://msdn.microsoft.com/library/default.asp…

What is _vti_cnf ?

Q: What is _vti_cnf?

A: This is a special folder created by Frontpage for use with IIS. Other folders may include _vti_script, _vti_pvt, or _vti_txt. For a complete list of FrontPage special files and folders, goto http://www.rtr.com/fpsupport/SERK/a_spfile.htm. This folder is not required for an ASP.Net application so it can be deleted manually.

Setting the Default Button in ASP.Net 1.1

Q: I have an ASP.Net 1.1 search form with several buttons on it (Search, Clear, Logoff) and a search word field. Currently, if the user enters text in the "Search Word” fields, and presses ENTER, the logoff button (located on the banner at the top of the form) is activated and the user is prompted if he wants to logoff. How can I change it so the ENTER key will activate the “Search” button instead? In other words, how can I make the “Search” button, the default button?

A: In ASP.Net the enter button executes the first button on the page. So create a button that is not visible (width is set to 1 px) and placed it at the top of the page before the logoff button. Change the background color if needed and make sure it cannot be seen. Then set the click event in .aspx page to execute the search button click event. When the user presses enter, the first button is executed and it will call the search method.

Accessing Version Number in .Net

Q: How do I programatically access the version number of an ASP.Net application?

A: The version number, and other general information, is kept in the AssemblyInfo.vb (for VB.Net projects). All information is housed in attributes in the file, as listed below:

Assembly: AssemblyTitle("MyApp")
Assembly: AssemblyDescription("A Sample Program")

To access the application version through .Net code, use
System.Reflection.Assembly.GetExecutingAssembly().GetName().Version.ToString(). The value displayed will be 4 sets of numbers, separated by '.' (similar to TCP/IP address). The version information for an assembly consists of the following four values:
Major Version
Minor Version

MSDN Beta Home Page

One of the tips I give to developers who want to stay up to date on the latest .Net information is to view MSDN web site (http://msdn.microsoft.com) regularly. It's a good idea to set it as your default home page so you can glance the headlines everytime you open a browser.

Expanding on that idea, Microsoft is now working on a Beta MSDN site (http://msdn.microsoft.com/aboutmsdn/betahomepage/default.htm) . The 2 big features of the new site are Country specific content and "My MSDN" for personalized content management.
