Yes, but i would like to not use MFC for that.
if i use the following code, we know that local address is lost and
therefore can not be used :

extern "C" __declspec(dllexport) LPTSTR GetString(HMODULE hwnd_DLL, int
Index);

extern "C" __declspec(dllexport) LPTSTR GetString(HMODULE hwnd_DLL, int
Index)
{
    static TCHAR *strRes;
    int iError;
    TCHAR re[2048] = {'\0'};
    strRes=&re[0];
    iError = ::LoadString(hwnd_DLL,Index, re, sizeof(re)/sizeof(re[0]));
    return(strRes);
}

i also tried to pass it by reference, but nothing has changed.
i tried also to turn the function to send back a string (STL), but
nothing works also...

Yes i understand but it means to link statically my resource string

So my question is how can i get the Handle of the DLL ?

No, you still can have resource string table in DLL. Just load the DLL
and store its handle somewhere.

HINSTANCE hResInst = ::AfxLoadLibrary(dllName);

CString strMessage;
strMessage.LoadString(hResInst, IDS_MESSAGE);

// ...

::AfxFreeLibrary(hResInst);
