[GD-General] Spy on windows 2k &Xp

[Vincent D. <sco...@ho...>]

This french article :
http://www.generation-nt.com/index.php?cat=astuces&id=38

talks about integrated spy in windows 2000 & Xp which take your Microsoft ID
& Hardware ID through regwizc.dll.
The command :
regsvr32.exe -u c:\windows\system32\regwizc.dll
will unload from system the DLL & spy.
Source code to unload will looks like :

OleInitialize(NULL);
HINSTANCE hLib = ::LoadLibraryEx (oTmp.c_str (), NULL,
LOAD_WITH_ALTERED_SEARCH_PATH);
if (hLib)
{
    HRESULT (STDAPICALLTYPE * lpDllEntryPoint)(void);
    (FARPROC&)lpDllEntryPoint = GetProcAddress(hLib, "DllUnregisterServer");
    if (lpDllEntryPoint)
    {
        if (FAILED((*lpDllEntryPoint)()))
        {
            // Error
        }
        else
        {
            // Ok
        }
     }
    FreeLibrary(hLib);
    OleUninitialize();
}

But how determine is DLL already unloaded ?

Thanks

Vincent.
