I have built a .net control which works well in XP and Win 2000, but fails in NT 4.0 and throws an exception FileLoadException.
Why would it fail in NT and work well in Win2000 and XP?
In my code, where I am declaring P/Invoke functions, I have the following:
static public extern int SetWindowTheme(IntPtr h, string s1, string s2);
But the thing is I do not call this unmanaged function in my entire control's source code.
Its just declared. That's all.
Do you think this could be causing the problem of FileLoadException when I try to run it in NT 4.0 (because there is no uxtheme.dll in NT 4.0).
Note that although I have declared it in my code, I never call this function at all.
Do you think I need to remove this declaration from my code and rebuild it to run it in NT 4.0 box.
