Hi everybody, I made a dialog using a resource file. When I use CreateWindowEx,in the code, to create a button or an edit control, it doesn't work : it returns 0, not the handle. Please What is the problem ???

did you specify a class name in your resource ? .rc: CLASS "myWindowClass" .asm: WindowClass db "myWindowClass",0 ;pointer for your windowclass HOPE THAT HELPS OLLI This message was edited by Typhoon, on 4/22/2001 10:12:23 PM

No that's not what I wanted to say: -I have a dialog made by a resource file. -I want to put a button in it using the code, not using the resource. The dialog is well-displayed but when, in the code, I use CreateWindowEx API, it returns 0, so it doesn't display a button. I checked the classes, ... Maybe the style of the dialog is wrong, I don't know. But I can't create the button. Mail me if you wan't to help me, and I will send you the code. Thanx very much. PS:if I use CreateWindowEx and RegisterClass to create my window instead of using resource, it works. I could do like that, but I would like to know what the matter is. My mail:cool:

The following code works for me:


DlgName     db "MyDlg",0
EditClass   db "BUTTON",0
Buffer      db 64 dup (0)

hInstance   dd ?


    invoke GetModuleHandle, NULL
    mov    hInstance,eax                     
    invoke DialogBoxParam, eax, ADDR DlgName, NULL, addr DlgProc, NULL           
    invoke ExitProcess, eax

DlgProc PROC hWnd:DWORD, uMsg:DWORD, wParam:DWORD, lParam:DWORD
    .IF uMsg == WM_INITDIALOG		
        invoke CreateWindowEx, NULL,\
                ADDR EditClass, NULL,\
                WS_CHILD or WS_VISIBLE,\
                100, 100, 100, 100,\
                hWnd, NULL, hInstance, NULL
        mov ecx, 32
            xor edx, edx
            shl ax, 1
            adc dl, 48
            mov Buffer, dl
            dec ecx
        .UNTIL ecx == 0

        invoke MessageBox, NULL, ADDR Buffer, NULL, MB_OK

    .ELSEIF uMsg == WM_CLOSE
        invoke EndDialog, hWnd, NULL

        mov eax,FALSE

    mov eax,TRUE
DlgProc endp

END start
With an rsrc.rc of:

#include "resource.h"
MyDlg DIALOG 10, 10, 277, 252

Thanx, I found my problem. You will laugh: I forgot to put "addr " before the caption of the button. maybe I was dreaming when I wrote this !:rolleyes:

I read all Iczelion´s tutotials. It helped me a lot with DIALOG BOXES, either with rc either with direct method: CreateWindowEx. Try it. Hope this help. :)
