[GD-Windows] CreateDialog failure

[Pierre T. <p.t...@wa...>]

Hi,

I create a dialog using something like :

handle =3D CreateDialog(
      hInstance,
      MAKEINTRESOURCE(IDD_DIALOG1),
      hWnd,
      NULL);

But returned handle is null, which means (I guess) something went wrong.

So I tried :

  DWORD Er =3D GetLastError();

Then retrieving the error string using FormatMessage (using the code =
snippet from the MSDN). But it doesn't help since error code is 0 and =
the translated string says there was no error.

Hmm. What do I do now ?
What are the usual reasons for CreateDialog to fail ?

In case it's important, the call takes place in a DLL dynamically loaded =
by a 3DS MAX plug-in, and hInstance and hWnd used to create the dialog =
are the ones from the MAX plug.
