GUI app and winAPI calls

Here is the declaration I use and it works great:

Code: (Select All)

Declare CustomType Library
    Function CreateWindowEx%& (ByVal dwExStyle As Unsigned Long, Byval lpClassName As Offset, Byval lpWindowName As Offset, Byval dwStyle As Unsigned Long, Byval x As Long, Byval y As Long, Byval nWidth As Long, Byval nHeight As Long, Byval hWndParent As Offset, Byval hMenu As Offset, Byval hInstance As Offset, Byval lpParam As Offset)
End Declare

You really only need to use the "A" suffix when calling directly from the DLL. If you use the header files instead, Windows will automatically select the "A" version. So you won't need CreateWindowExA in my declaration but you would if you pulled it from the DLL.
