Combo text update

[hmm]

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.. 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

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.

[hmm]

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

Thanks CornedBee !
