Problem with Combo Box

Can't get a combo box to display its content. If I query for its content, it seems to be working fine. CB_GETCOUNT returns the correct number, for example. I'm not sure what to make of it...

Code:

DLG_MASTERCONFIGURE DIALOG 0, 0, 260, 140
.....
   BEGIN
      .....
      COMBOBOX                               IDCMB_SCREENNUM,   18, 88,  35,  13, CBS_DROPDOWNLIST | CBS_SORT | WS_VSCROLL
      .....
   END

Code:

    case WM_INITDIALOG:
     {
      int si;
      char ScreenNum[3];
      for(si = 1; si <= NumberOfScreens; ++si)
       {
        snprintf(ScreenNum, 3, "%i", si);
        SendDlgItemMessage(hDlg, IDCMB_SCREENNUM, CB_ADDSTRING, 0, (LPARAM)ScreenNum);
       }
     }
    break;

Because the combobox is too small (the height). Try to change to:

Code:

COMBOBOX IDCMB_SCREENNUM,18,88,35,100,CBS_DROPDOWNLIST|CBS_SORT|WS_VSCROLL

Now it will expand the list since 100px height, and if there's more items it will also show a vertical scroll bar.

Hope that helps

Ah, you can also set the first item selected using:

Code:

SendDlgItemMessage(hwnd,IDCMB_SCREENNUM,CB_SETCURSEL,(WPARAM)0,0);

The height corresponds to the list portion? That's annoying. Thanks for the tip.

Yes, the height in that case it corresponds to the max height that the expanded list can have. So if you set a height of 100px and 3 items to show each of 25px, it will show a list of 3*25px, but if you have 5 items it will show a list of 100px with a vertical scroll (if you have defined that the control can have a vscroll, of course). Or that's how I understand that, if it's wrong please correct
