Combo text update

OS Win98
Compiler: VC6++
Subject: Combo boxes

Trying to insert/add a string a combo box, but failing. I don't get an error but the string isn't added. Pointers?

Code:

case WM_COMMAND:

switch(wParam){

case BS_PUSHBUTTON:
if (SendMessage(hCombo,CB_ADDSTRING ,0,(LPARAM)"ABCDEF")!=CB_ERR)
UpdateWindow(hCombo);
MessageBox(hwnd,"Combo updated","",MB_OK);
break;


Thanks

hmm

hmm.. did you draw the ComboBox in a dialog?? than you should drag the box to fit at least one item... for more info look at: http://winprog.org/tutorial/dlgfaq.html

Thanks Jop,

No, I used the CreateWindowEx function to create it.

Code:

hCombo = CreateWindowEx(
NULL,"COMBOBOX","Copy Disk:",
WS_CHILD|WS_VISIBLE|CBS_DROPDOWNLIST|CBS_AUTOHSCROLL,
25, 20, 150, 5,hwnd, NULL, hInstance, NULL);

I'm sure its something simple I'm missing :confused:

:)

hmm

case BS_PUSHBUTTON:

is the id of your button really BS_PUSHBUTTON? Is the code actually called (does the message box show up)?

Anyway, you have to set a far larger height value in your CreateWindowEx call. The height you specify there is for the extended list too.

It was the height property that was causing the problem! Should have seen that one :eek:

Thanks CornedBee !
