how to convert a HDC to IntPtr ?

I'm not sure that I understand. There is no HDC type in C#, so most programmers
just use an IntPtr in place of it. Could you describe the context of the
problem that you're trying to solve. Perhaps, a little code sample would
illuminate the issue.

What Win32 namespace? The only Win32 namespace that I am aware of in the
..NET Framework is the Microsoft.Win32 namespace but that doesn't contain
an HDC type. Is this from a third-party library?

That means that you are using PInvoke interop to call into unmanaged code,
right?
Your function declaration should specify the HDC as IntPtr, the interop
layer will marshal the HDC (a void*) to IntPtr on return.

i did like you wrote before and it's ok.
thx.

Seems like you don't even use C#, so I would suggest you to post C++ related
questions to the vc NG.
