Child window ID's not recognized by GetDlgItem()

vorticidal (29)
My code creates some windows that are children of the main app window. The child windows are assigned child-window identifiers through the hMenu parameter of the CreateWindow function. However, only the child windows with a child-window identifier that is a multiple of 4 can be retrieved by a call to GetDlgItem(). It also happens that the HWND's retrieved by GetDlgItem() for child window identifiers 5000,5004,5008 correspond to the three first created children.
If this is how the code should work, is there a way to assign arbitrary child-window IDs to children of the same window?

Pointer arithmetic, the c-style cast has priority. Wrap your expression in parentheses. Alternatively, prefer a c++ style cast. http://en.wikipedia.org/wiki/Static_cast

So, HMENU is actually a pointer? I'd never guess it... Thank you very much.
