ASM Community

I do something in the .rc files(EDITTEXT,COMBOBOX...),and the main of .asm file to compile the main-window is:

start:
invoke	GetModuleHandle,NULL
mov	hInstance,eax
invoke	DialogBoxParam,hInstance,DLG_MAIN,NULL,offset DlgProc,NULL
invoke	ExitProcess,NULL
end	start

How can I change it into .cpp file(just use API,not MFC)?

int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInst,
	 LPSTR lpszCmdLine,int nCmdShow)
{
	hInstance = GetModuleHandle(NULL);
	DialogBoxParam(hInstance,"DLG_MAIN",NULL,(DLGPROC)DlgProc,NULL) ;
	ExitProcess(NULL);
                return 0;
}

int WINAPI WinMain(HINSTANCE hInstance,HINSTANCE hPrevInst, LPSTR lpszCmdLine,int nCmdShow) {
	return ((INT)DialogBoxParam(hInstance,DLG_MAIN,NULL,(DLGPROC)&DlgProc,NULL));
}

Assuming that you have a valid resource whose identifier is defined as "DLG_MAIN".

Yu don't have to call GetModuleHandle, because the C runtime does it for you. You don't call ExitProcess, because you have to give the runtime a chance to unload itself. The "&" sign is equivalent to the 'addr' or 'offset' in asm. Without the "&" you order the program to call the function and treat its return value as the parameter. Normally the type-checking would complain here and the program would not compile.
