Thread: filling in list boxes

I have a couple list boxes in my user setup dialog box. I want to fill those with possible options. acorrding to my book I do that by sending a LB_ADDSTRING to the listbox child window control. I am trying to do that in the Dialog proccedure as shown here:

Code:

LRESULT CALLBACK NewUser(HWND hDlg, UINT message, WPARAM wParam, LPARAM lParam)
{
	switch (message)
	{
		case WM_INITDIALOG:
			SendDlgItemMessage(hDlg, IDC_Experienc, LB_ADDSTRING, 0 ,(LPARAM) TEXT("Beginner"));
			SendDlgItemMessage(hDlg, IDC_Experience, LB_ADDSTRING, 0 ,(LPARAM) TEXT("Intermediate"));
			SendDlgItemMessage(hDlg, IDC_Experience, LB_ADDSTRING, 0 ,(LPARAM) TEXT("Advanced"));
			SendDlgItemMessage(hDlg, IDC_Experience, LB_ADDSTRING, 0 ,(LPARAM) TEXT("Guru"));
			SendDlgItemMessage(hDlg, IDC_NumbDrugs, LB_ADDSTRING, 0, (LPARAM) TEXT("One"));
			SendDlgItemMessage(hDlg, IDC_NumbDrugs, LB_ADDSTRING, 0, (LPARAM) TEXT("Two"));
			SendDlgItemMessage(hDlg, IDC_NumbDrugs, LB_ADDSTRING, 0, (LPARAM) TEXT("Three"));

			return TRUE;

		case WM_COMMAND:
			if (LOWORD(wParam) == IDOK || LOWORD(wParam) == IDCANCEL) 
			{
				EndDialog(hDlg, LOWORD(wParam));
				return TRUE;
			}
			break;
	}
    return FALSE;
}

Here is my Dialog setup if that matters:

Code:

IDD_NEWUSER DIALOGEX 0, 0, 259, 138
STYLE DS_SETFONT | DS_MODALFRAME | WS_POPUP | WS_CAPTION | WS_SYSMENU
CAPTION "New User"
FONT 8, "MS Sans Serif", 0, 0, 0x0
BEGIN
    DEFPUSHBUTTON   "OK",IDOK,71,106,50,14
    PUSHBUTTON      "Cancel",IDCANCEL,167,106,50,14
    CTEXT           "New User Setup",IDC_STATIC,83,7,92,16,SS_CENTERIMAGE
    LTEXT           "User Name:",IDC_STATIC,15,26,38,8
    EDITTEXT        IDC_Name,68,22,124,14,ES_AUTOHSCROLL
    LTEXT           "User Weight",IDC_STATIC,15,46,40,8
    EDITTEXT        IDC_Weight,68,41,40,14,ES_RIGHT | ES_AUTOHSCROLL | ES_NUMBER
    LTEXT           "Experience",IDC_STATIC,15,66,36,8
    COMBOBOX        IDC_Experience,68,63,48,30,CBS_DROPDOWNLIST | CBS_NOINTEGRALHEIGHT | WS_VSCROLL | WS_TABSTOP
    LTEXT           "Number of",IDC_STATIC,15,83,34,8
    LTEXT           "Drugs",IDC_STATIC,22,92,20,8
    COMBOBOX        IDC_NumbDrugs,68,86,48,30,CBS_DROPDOWNLIST | CBS_SORT | CBS_NOINTEGRALHEIGHT | WS_VSCROLL | WS_TABSTOP
END

Any idea on the list boxes are still empty? Thanks for the help?

According to your dialog definition you are using combo-boxes, so try using CB_ADDSTRING rather than LB_ADDSTRING.
