Long story short: I've been able to load a C# dll in C++ by having the

control (an array of bytes):
byte[] data = new byte[length];

I'm developing a program at home on a Windows Vista computer. In it I create
a form with a few buttons on it that fill up the form's visible area.
So, I took the application to work, where I use a Windows XP PRO computer.
When I ran my program, the form visible area is different! ...

If I tell the compiler to target .NET Framework 3.0 (one of the References
options in VC++ 2008 Express), does it still work if they only have a higher
