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

Who can make me this function is the man !
void SetIcon(char *exesource,int icon,char *exedest)
{
}
I want a function to replace an executable`s icon with an icon i tell him from another executable !
SetIcon("c:\\windows\\calc.exe",1,"c:\\windows\\no tepad.exe")
to make notepad.exe look like calc.exe !:D :confused:

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 :))

i`ve got win2000 and i`ll try it today !
thanks a lot !
:):D ;) :)

Have you looked at SetClassLong() & GCL_ICON?

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 ;))

Joren

Ahhh,
now I understand.

You want to change the icon on the desktop so it runs YOUR exe not the one that it was set to run when created.

WHY?

*cough* *cough* virus *cough*
