GoAsm, Going from windows 7 to windows 10
.code
start:
149 invoke [GetModuleHandleA], NULL ; this is the line giving the error
150 with or without the square brackets
160 mov Q[hInstance],rax
Line 149 of assembler source file shdc61.asm. use square brackets to
address memory, address or offset to get address.
Thanks for any help.
It looks like the symbol NULL has not been defined, so perhaps missing an #include file.
Thank you WJR for responding.
All my programs in windows 7 were written in GoAsm, none
of which had brackets around NULL. I enclosed NULL in
brackets and the error is gone.
I don't understand and have never read anything about
enclosing NULL in brackets.
Evidently there are a lot of changes from windows 7 to windows 10.
Here is a problem, with "wndclassexa".
Would someone be so kind as to give some book of where to read
about this problem or some code examples Please.
WinMain:
FRAME hInst,hPrevInst,CmdLine,CmdShow,vInst
LOCAL wc: WNDCLASSEXA ],msg,hWnd,HWND,RR:RECT
mov D[wc.cbSize],SIZEOF WNDCLASSEXA
mov D[wc.style],CS_BYTEALIGNWINDOW | CS_HREDRAW | CS_VREDRAW
mov rax,offset WndProc
mov Q[wc.lpfnWndProc],rax
mov D[wc.cbClsExtra],NULL
mov D[wc.cbWndExtra],NULL
push [hInst]
pop [wc.hInstance]
invoke LoadIcon,NULL,IDI_APPLICATION
mov Q[wc.hIcon],rax
invoke LoadCursor,NULL,IDC_ARROW
mov Q[wc.hCursor],rax
invoke CreateSolidBrush,00ffffffh ; white background
mov Q[hBrush],rax
mov Q[wc.hbrBackground],rax
mov Q[wc.lpszMenuName],NULL
mov Q[wc.lpszClassName],offset szDisplayName
mov Q[wc.hIconSm],0
invoke RegisterClassEx, addr wc
If you had a 64-bit program that you could build and run on Windows 7, then most likely it should build and run on Windows 10.
NULL should not be in square brackets. The error has just been pushed off as an external symbol that the linker is not going to find. If you have used #include windows.h, and if needed setup your INCLUDE environment string properly, then GoAsm should find the definition for NULL.
As for the "wndclassexa" problem, you do not mention the error, but there shouldn't be a ] after LOCAL wc:WNDCLASSEXA.
hello,
sorry,i have not see that you want convert your source fron goasm to goasm
