Hi all,

When I try to use API functions in Windows Form all I get ar
compilation errors. MSDN doesn't help at all in this case. Here is m
code:
(I test it with very simple one Rectangle since I want to do som
drawing)

public __gc class APIFunctionality
{
public:
[System::Runtime::InteropServices:DllImport("GDI32.dll")]
static bool Rectangle(IntPtr hdc, int t, int l , int r, int b);

};

This is the only form of the code that actually compiles . I found i
MSDN some info how to do it, but it simply didn't compile. Also by MSD
there is no DllImport, only DllImportAtributes. Anyway, above sectio
compiles, and here is my usage in Picture Box (all very basic an
simple ):

Graphics * m = e->Graphics;
APIFunctionality::Rectangle(hdc, 30, 100, 100, 100);
m->ReleaseHdc(hdc);

This also compiles, but doesn't work at all .
Does anyone know how to do this in C++ or has any idea where I can fin
good info about it? Appreciate it
