Hi,
First I have to say that I enjoy coming back to Assembly language. I decided to use GoAsm because of the Unicode support which is important for my applications. So many thanks to Jeremy Gordon for the Go Tools and also to KetilO for RadAsm ! :U
I only have one question about GoAsm : how to use RegisterClassEx to give my main dialog a custom class name ?
(instead of the original "#32770").
I did it with Masm32 and it worked fine, but never succeeded to have it work with GoAsm both Ascii or Unicode.
It looks like the class is registered as I have no error but the Dialog just doesn't show ! Same problem with modal or modeless dialogs.
Thank you in advance for any solution,

Hi PhM, welcome to the forum, and thanks for your comments.
As for your problem with RegisterClassEx, are you having trouble with the CLASS statement in the resource file, or in setting the cbWndExtra member of the WNDCLASSEX structure to DLGWINDOWEXTRA (value 30 decimal)?
Thanks for your remply,
Here's the code I use (in the dialog resource editor I fill the "Class" edit box with Custom_Class) :
DATA SECTION
hInstance DD ?
szClassName DW "Custom_Class",0 ;this is the custom class name for my dialog...
...
start:
push 0
call [GetModuleHandle]
mov [hInstance],eax
invoke _RegisterClass,[hInstance]
call _InitComControls
;Dialog creation...
push 0
push offset DlgProc
push 0
push IDD_DLG1
push [hInstance]
call [DialogBoxParam]
push 0
call [ExitProcess]
;This is the function I use to register my custom dialog class...
_RegisterClass FRAME hInst
LOCAL wc:WNDCLASSEX
mov D[wc.cbSize],sizeof WNDCLASSEX
mov D[wc.style],CS_HREDRAW or CS_VREDRAW
mov [wc.lpfnWndProc],offset DlgProc
mov [wc.cbClsExtra],NULL
mov [wc.cbWndExtra],DLGWINDOWEXTRA
push [hInst]
pop [wc.hInstance]
invoke GetSysColorBrush,COLOR_BTNFACE
mov [wc.hbrBackground],eax
mov [wc.lpszMenuName],NULL
mov [wc.lpszClassName],offset szClassName
invoke LoadIcon,NULL,IDI_APPLICATION
mov [wc.hIcon],eax
mov [wc.hIconSm],eax
invoke LoadCursor,NULL,IDC_ARROW
mov [wc.hCursor],eax
invoke RegisterClassEx,addr wc
;mov [wc],eax
ret
endf
_InitComControls FRAME
local iccex:INITCOMMONCONTROLSEX
mov D[iccex.dwSize],SIZEOF INITCOMMONCONTROLSEX
mov D[iccex.dwICC],ICC_WIN95_CLASSES
push ADDR iccex
call [InitCommonControlsEx]
RET
endf
This solution worked correctly with Masm 32. I always use this solution with my C or C++ Apps.
Thank you very much for your help,
Sincerly,
PhM
Hi jorgon,
I attached a zip of the RadAsm project to this reply, better than making mistakes typing the code !

Hi PhM
In the files you posted, in the INITDIALOG routine, I noticed a spare "pop ebx" just before the jump to exit. If it is correct that this is not supposed to be there it would be throwing the stack out by 4 bytes at an early stage of dialog-creation probably causing the dialog not to appear.
Sorry I haven't retried your code with this removed, because I do not have my machine set up to use Radasm.
