Can i use OLE2

Windows 7
Create object link to FuelDirect — OLE2 application.

I believe most (if not all) ActiveX/COM objects out there today are OLE 2.0 objects. However, specifically you’re probably asking if our ActiveX/COM containers support something like OleLink (http://msdn.microsoft.com/en-us/library/windows/desktop/ms682297(v=vs.85).aspx), and that we do not.

so any way to works RS Or Xojo

We’d need to add that ability to our OLEContainer, otherwise you could implement your own OLEContainer (not trivial), so best bet is to file a feature request for it.
