XNAMessageBox, NumberOnlyTextbox, and Allowing DoubleBuffering in WinForms

I started learning HTML in 7th grade (2007) then went on to learn any and everything I could.
HTML/CSS/JavaScript/ActionScript/ASP.Net (6 years)
Basic (5 years)
C/C++ (4 years)
Java (4 years)
C# (3 years)
VB (2 years)

Out of all of these I have to say C# is by far my favorite since its wide spread, works for almost any solution and allows me to use Visual Studio.
