ACC vs DLL Function

[xxxPAMxxx]

Or, try to use single function child() to find visible button. You need to include button style, which is different for visible and invisible controls.

int hwnd=child("" "AfxWnd42s" "My Dialog" 128 style)
but hwnd

Here 128 is flag that tells to interpret x as style. Control style is displayed in QM status bar, second line.

I did the following:

int hwnd=child("" "AfxWnd42s" "My Dialog" 128 0x58000004)
but hwnd


and gave me "missing last argument error." What did I miss?
