Title: looking for a combobox example/skeleton
Post by: iaNac on September 28, 2006, 09:41:17 PM
Hi - I've figured out how to create and populate a combobox but I'm having trouble reading the selection.  I've searched for an example in this forum and struck out (or overlooked it?).  I'd really like to learn about them in detail.  Can anyone help?

Thanks

I learned this from a friend...

Assumming that your combobox is called IDC_COMBO;

Code Select

mov eax, wParam
.if ax==IDC_COMBO
    shr eax, 16 ; monitor selection change
    .if ax==CBN_SELCHANGE
         invoke SendDlgItemMessage, hWin, IDC_COMBO, CB_GETCURSEL, 0, 0
            .if eax==0 ; selected option 1
; do something
    .elseif eax==1 ; selected option 2
; do something

                .
                . etc...
                .

    .endif
    .endif
.endif


Just remember that the counting starts from 0...  hope this helps. :)

    Is it really necessary to subclass the edit control? Can't i just process the WM_CHAR/WM_KEYDOWN from the MainWinddowProc? Thanks anyway. You've been helpful.
   Bye form I....

With combobox  and other control ,you need only  sendmessage,Hcombo,.....
WM_GETTEXT  general control
LB_GETTEXT   listbox
CB_GETTEXT combobox
No need of subclass procedure.

    I've been looking into some examples and it seems i need to get the handle from combo's edit control and subclass it to process CR ( ENTER ) keystrokes.
    Is this correct or is there any other way?
    Bye and bests from X.

               subclass ?
               I did this example, i hope it help you (.zip=.asm, .inc, ...)
               The combo is called form a dialog box not from the main window
