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

Working with double quotes (") in VB.Net

String manipulation in VB2005 is fairly simple. However, things can get a little tricky with the double quote character. How do you look for it in a string? How can you insert into a string? How do you remove it from a string? These are questions that may lead to confusion if you don't know what you're looking for. Ironically enough, in VB the double quote can also be used as an escape character when searching for it in a string. For example: Dim strTest As String strTest = """123""" 'Displays "123" (double quotes appear in the final result) strTest = """""123""" 'Displays ""123" (double quotes appear in the final result) strTest = "test\""test" 'Displays test\"test strTest = "test""test" 'Displays test"test In cases where you want to insert a double quote character, simply reference it unicode character designation, ch...

FoxCon 2019

This year I had the privilege of being invited to FoxCon for the 5th time.  FoxCon is a private invite-only conference.  It was started decades ago when FoxPro was one of the products from Microsoft.  Although the product is no longer supported, it is still widely used and loved at many organizations of various sizes.  The FoxCon conference targets FoxPro related topics but the organizers are always open to hear new topics. This year I presented 2 sessions: "SQL Server Security"  and "New Features in SSRS 2017".  Presenting to a technical audience is something I have always enjoyed.  However, it seems much more enjoyable presenting to this group of tech experts. I look forward to attending and possibly presenting again next year.
