SetItemChecked(index,boolean) VS SetItemCheckState(index,Checkstate)
I just stumbled upon the SetItemChecked and SetItemCheckState when working on a checked listbox. The SetItemChecked takes an listindex and True/false to either set the listitem to checked or unchecked.

You can find out a great deal about the internals of an application through reflection, it's exposed by the .NET BCL (base class library) and it makes it trivial to retrieve actual IL for any .NET method. Reverse engineering on Wikipedia: Reverse engineering is the process of discovering the technological principles of a device,...

Multiple versions of .NET CLR running concurrently
Let's say I have a .NET user application (.exe) running under Windows that was compiled in .NET Framework Version 3.0 (VS2008). If that application loads another .NET Assembly (.dll) that was compiled on a different computer using .NET Framework Version 2.0 (VS2005), will the loaded assembly use the existing 3.0 runtime (which will run ...
C# Extension Method - String Split that also accepts an Escape Character
I'd like to write an extension method for the .NET String class. I'd like it to be a special varation on the Split method - one that takes an escape character to prevent splitting the string when a escape character is used before the separator. What's the best way to write this? I'm curious about the best non-regex way to approach it....

I know it's quite easy to code, but I'd rather reuse the framework classes if the functionality...
