Correctly matching an ending tag with its starting tag in HTML with a RegEx
I'm using VB.Net in an ASP.Net 2.0 app to run some regular expressions that remove some unnecessary markup. One of the things that I'd like to do is remove span elements that don't have any attributes in them: output = Regex.Replace(output, "<span\s*>(?<Text>.*?)</span>" & styleRegex, "${Text}", RegexOptions.Compiled Or RegexOptions.Cul...

Question about Type Comparison ASP.NET and DBNull
I have a function that pulls articles records from an MSSQL database. Some are URLs to PDFs, and other are actual articles stored in the SQL.

asp.net unhandled exception
I have an application that has been running in produciton for a while now, and every now and then it throws an akward exception that I catch in the global.asax session error event.

Why Encoding.Default.GetBytes() returns different results in VB.NET and C#?
We recently came across some sample code from a vendor for hashing a secret key for a web service call, their sample was in VB.NET which we converted to C#. This caused the hashing to produce different input. It turns out the way they were generating the key for the encryption was by converting a char array to a string and back to a by...

Does VB.NET perform any multi-threading on its own?
I know .Net and C# pretty well, but never even looked at VB. My problem is: our Win32 COM library is used by a number of clients, and we see that the number of failures is higher for those who use the library from VB (both VB and VB.NET) than for those who use C++, C# or Delphi. One thing about our library is that it is supposed to be u...
How do I specify the equivalent of volatile in VB.net?
I'm attempting to write a lock-free version of a call queue I use for message passing. This is not for anything serious, just to learn about threading. I'm relatively sure my code is correct, except if the instructions are re-ordered or done in registers. I know I can use memory barriers to stop re-ordering, but how can I ensure values ...

Is there a way to build a new type during Runtime?
I am going to ask a question that might sound weird. Is there a way to build a new class during Runtime? Or at least, add a new property to an existing class. I mean creating a class that doesn't exist and not an instance of an existing class. I could later on use reflections to load and use this class. ...
