How to locallize a plug-in DLL file?

[forester]

I have experiences to localize a few MFC executable files, first create a resource dll file then add following code in InitInstance():

BOOL CMyApp::InitInstance()
{
   //Default Application Wizard code.
   HINSTANCE hRes = NULL;
   hRes= LoadLibrary("ResourceD.dll");
   if(hRes)
      AfxSetResourceHandle(hRes);
   //Rest of wizard code
   return CWinApp::InitInstance();
}

Now I need to localize a dll file which is an IE web browser toolbar, who could tell me how localize the dll file? Thank you!
