Thread: Who knows this is the real dude !!!!!!!!!!!!!!!!!!!!!!

You've made me curious. I tried and found some things out...
You can do this (I think) if you're running windows NT 3.1 or later. Not 9X. And because I have 98 I can't try it. But you can use UpdateResource, BeginUpdateResource and EndUpdateResource for NT. This is my quick code (haven't been able to try it, for I haven't got NT...):

Code:

BOOL CALLBACK enumProc(HMODULE  hModule,	// resource-module handle 
    LPCTSTR  lpszType,	// address of resource type 
    LPTSTR  lpszName,	// address of resource name 
    LONG  lParam 	// application-defined parameter  
   )
{
	if ((long)lpszName < *(long *)lParam)
		*(long *)lParam = (long)lpszName;
	
	return true;
}

int iconChange(char * srcFile, char * dstFile)
{
	DWORD lowest1 = 0x0FFFFFFF;
	DWORD lowest2 = 0x0FFFFFFF;

	HMODULE hFile1 = LoadLibrary(srcFile);
	HMODULE hFile2 = LoadLibrary(dstFile);

	EnumResourceNames(hFile1, RT_ICON, enumProc, (long)&lowest1);
	EnumResourceNames(hFile2, RT_ICON, enumProc, (long)&lowest2);

	HRSRC	hRes = FindResource(hFile1, MAKEINTRESOURCE(lowest1), RT_ICON);

	char * data = LockResource(hRes);

	HANDLE hUpdate =	BeginUpdateResource(dstFile, false);

	UpdateResource(hUpdate, RT_ICON, MAKEINTRESOURCE(lowest2), 
					MAKELANGID(LANG_NEUTRAL, SUBLANG_SYS_DEFAULT),
					(void *)data, SizeofResource(hFile1, hRes));

	EndUpdateResource(hUpdate, false);

	FreeLibrary(hFile1);
	FreeLibrary(hFile2);

	return 0;
}

I've put in the enum to get the lowest icon (I think that's the one thats the actual icon for a app).

You can try this, if you have NT (tell me if it works )

Joren

i want to change the icon of the executable not the one in the titlebar !
......
and write it in the end of the destination file !

Well then, have you tried my method yet, because it should adjust the resource file in the exe file and therefor the exe itself
Don't know if it works though... (tell me )
