changing the icon of a window

hi gurus

I try to make an exe to change the icon of a window of an other application.

here my code :

#include "stdafx.h"
#include <winbase.h>
#include <windows.h>



int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,LPSTR lpCmdLine,int nCmdShow)
{

HWND hWnd;
HICON hIcon;

// AUDROS (5.5) is the title of the window of I want to change the icon

hWnd = FindWindow(NULL, "AUDROS (5.5)");

if (hWnd)
{
hIcon = (HICON)LoadImage(NULL, "ico00001.ico", IMAGE_ICON, 16, 16, LR_LOADFROMFILE);

SendMessage(hWnd, WM_SETICON, ICON_SMALL, (LPARAM)hIconSmall);
}

return(0);
}


It change the icon but as soon as the window is activate, my icon is replace with a defaut one !!!!

any help ?
thanks

The problem is that the icon handle gets destroyed as soon as your application terminates. You need to inject some code into the target process and execute LoadImage in the context of the target process. This way the icon handle will be accounted for that process and will remain valid as long as the target process exists.

Yes, it's the problem.
What I do now is I keep my exe alive as long as my AUDROS application is alive. So the icons stay correct.

Thanks.
