Help with adding strings into ComboBox using Window Handle

I have no idea what's wrong with my code, please help!

Code:

---


BOOL CALLBACK FileDlgProc(HWND hwnd2, UINT Message, WPARAM wParam, LPARAM lParam){
    switch(Message){
        case WM_CREATE:{
          HWND handle;
          LRESULT l;

          handle = NULL;
          handle = GetDlgItem(hwnd2, ID_S_C);
          if (handle == NULL){
              MessageBox(hwnd2, "handle == NULL", "........", MB_OK);
          }
          l = SendMessage(handle, CB_ADDSTRING, (WPARAM) 0, (LPARAM) "Name");
          l = SendMessage(handle, WM_SETTEXT, (WPARAM) 0, (LPARAM) "Name");
          l = SendMessage(handle, CB_ADDSTRING, 0, (LPARAM) "Telephone");
          l = SendMessage(handle, CB_ADDSTRING, 0, (LPARAM) "Email");
        }
        break;
        ... //omitted
  }
  ...//omitted
}

Assuming my control id is correct, can anyone help by telling me what's wrong with this? I just couldn't get this to work......

Thanks in advance.

Post a code snippet showing how you create your combobox.

Code:

---

IDD_FILE DIALOGEX DISCARDABLE  0, 17, 259, 300
STYLE DS_MODALFRAME | WS_POPUP | WS_CAPTION
FONT 8, "MS Sans Serif"
BEGIN
    PUSHBUTTON      "&Search", ID_SEARCH, 200, 20, 50, 14
    COMBOBOX        ID_S_C, 13, 20, 120, 200, CBS_DROPDOWNLIST | WS_VSCROLL | WS_TABSTOP
    PUSHBUTTON      "&Add", ID_ADD, 200, 65, 50, 14
    PUSHBUTTON      "&Edit", ID_EDIT, 200, 82, 50, 14
    PUSHBUTTON      "&Delete", ID_DELETE, 200, 99, 50, 14
    COMBOBOX        ID_GROUP, 13, 38, 60, 100, CBS_DROPDOWNLIST | WS_VSCROLL | WS_TABSTOP
    LISTBOX        ID_LIST, 13, 65, 120, 150, LBS_NOTIFY | WS_BORDER | WS_VSCROLL
END

It was created from my .rc

Change WM_CREATE to WM_INITDIALOG and give it a try.

In other words use this
case WM_INITDIALOG:
instead of this
case WM_CREATE:

Thanks, now I can ADDSTRING, but SETTEXT doesn't seem working...

Well, how about posting more detailed info on your SETTEXT issue such as a code snippet illustrating the problem?

I'm assuming you are wanting to select the "Name" string you just added. Try using the CB_SETCURSEL message.

All problems are solved, thanks!
