Ok, I tried this:
.data?
hInstance HINSTANCE ?
CommandLine LPSTR ?
wc WNDCLASSEX <>
msg MSG <>
hWnd HWND ?
uMsg UINT ?
wParam WPARAM ?
lParam LPARAM ?
....
WinMain proc ;nothing here
;get rid of LOCALS
...works fine...
WndProc proc hWnd:HWND, uMsg:UINT, wParam:WPARAM, lParam:LPARAM
...works fine...
I change that to:
WndProc proc ;nothing here
and it compiles ok but no window comes up. I'm using ICZ Tut3 for sample. I think it has something to do with the way that the data is setup
Any help would be apprecieated
You can learn and try this..
..and forget about WndProc..just copy&paste!
You will work with MainMessages only!
Good luck
.data
ALIGN 4
MainMessages DD WM_COMMAND, OnCommand
DD WM_CREATE, OnCreate
DD WM_DESTROY, OnDestroy
DD WM_PAINT, OnPaint
....
....
nMessages DD $-MainMessages
.code
WndProc PROC ;
mov eax, nMessages ;u
mov ecx, offset MainMessages ;v
shr eax, 3 ;u get number of messages to do
mov edx, ;v get uMsg in edx
WndProc_1: ;
dec eax ;u
jl DefWindowProc ;v l=message not found
cmp ,edx ;u see if its the correct message
jnz WndProc_1 ;v no
push esp ;u save registers as required by Windows
push ebp ;v
push ebx ;u
push edi ;v
push esi ;u
call dword ptr ;v
;call correct procedure for the message
;now =hwnd,=umsg,=wparam,=lparam
pop esi ;u
pop edi ;v
pop ebx ;u
pop ebp ;v
pop esp ;u
jc DefWindowProc ;v nc=don't call DefWindowProcA eax=exit code
;
pop edx ;u
pop ecx ;v
pop ebx ;u
pop ecx ;v
pop ebx ;u
push edx ;v
ret ;ret 16
WndProc ENDP ;
I can't seem to get it working so I'm just gonna settle with local for now until I understand windows a little better :)
The hWnd in
.data?
hWnd HWND ?
WndProc proc hWnd:HWND, uMsg:UINT, wParam:WPARAM, lParam:LPARAM
