ComboBox Notification Problems

[Fromethius]

Hello everyone and thank you for taking the time to read my post,

I have this code:

        case WM_COMMAND:
           {
              switch(LOWORD(wParam))
              {
                 case hwndCombo:
                 {
                    switch(HIWORD(wParam))
                    {
                       case CBN_DROPDOWN:
                       {
                          MessageBox(hwnd, "OK", "OK", MB_OK);
                       } break;
                    } break;
                 } break;
              } break;
           } break;

Also, I have hwndCombo initialized right after I create my window. Don't worry, I know it is initialized before WM_COMMAND runs:

wndCombo = GetDlgItem(hwnd, 30000);

My combobox resource is defined as 30000.





Anyways, when I try to compile this code I get this error:

`hwndCombo' cannot appear in a constant-expression

Thanks for any help given.

Can I get any help on this one?

hwndCombo is being used as a case in a switch statement. Cases must be constant integer values.
