Hello, I wrote a dll in VC++ that creates a window. This dll is called from a VB application. I'm trying to do this window be the main VB form, by passing its handle to the dll, as shown below: Relevant dll code:
int _stdcall InitMainWindow(HWND hWnd)
{
    WNDCLASSEX wc = { ... };
    RegisterClassEx( &wc );

    hWnd = CreateWindow( ... );
	
   ShowWindow( hWnd, SW_SHOWDEFAULT );
   UpdateWindow( hWnd );

   ...
}

Relevant VB code:
Public Declare Function InitMainWindow Lib "DLL_Test_Window.dll" (ByVal hWnd As Long) As Long

Private Sub Form_Initialize()
   Call InitMainWindow(Me.hWnd)
End Sub

But this doesn't work. The created window doesn't "substitute" the form window. Actually, I would like to render a scene in the VB form background and add some controls on it (textboxes, labels and grids). I already made this using Direct3D directly with VB. But now I would like to use the window created by the dll as the form. Is this possible? Thanks in advance

Oh... where was my mind?! The VB form is already a real window. I don't need to create a new window in the dll. Just passing Me.hWnd to the dll for starting the render device is enough.

Thanks and sorry for the confusion.

Yup. In any case, the other way around isn't possible afaik - a vb form (actually a system.windows.forms form) is a bit more complex than a windows window, and I don't know of any way to make one use a pre-created windows window.
