Once again you were right about the va_arg! I was sending a few BYTES!! My mistake!! As soon as i corrected it, it worked!! But after a while i changed something, don't remember what, and it stopped!

In the DOS/WINDOWS character set, character 26 (^Z)(Control + Z) is assigned as the end of file character for text files.

When we issue the copy con command at the dos prompt, we type text and to terminate we press ^Z.

Apparently CComboBox::GetComboBoxInfo[^] can give you a handle to the list control.

There are two thing I am not sure about and I would like to ask: In the height calculation I needed to add 2 pixels for the border, is there a better alternative than using a magic value?

I didn't understand from MSDN what SWP_NOOWNERZORDER [^] is for? I replaced it with SWP_NOZORDER, hope this is okay.

You can check if SM_CYFIXEDFRAME returns the correct value. Interestingly enough I did not have this problem

Btw, GetCount()[^] returns not a zero based index.

CRect Outer, Inner;

list.GetWindowRect(&Outer);
list.GetClientRect(&Inner);
list.ClientToScreen(&Inner);

int LeftBorder   = Inner.left   - Outer.left;
int TopBorder    = Inner.top    - Outer.top;
int RightBorder  = Outer.right  - Inner.right;
int BottomBorder = Outer.bottom - Inner.bottom;
