I don't know if this information is in your strConnectionString, but I read in help that :

"For all custom data provider the mk:@MSITStore:C:\Program%20Files\Codejock%20Software\ActiveX\Xtreme%20SuitePro%20ActiveX%20v11.2.2\Help\SymbolReference.chm::/XtremeCalendarControl~CalendarDataProvider~ConnectionString.html - ConnectionString  must contain "Provider=custom".  "
