May be not the best choice, but what I'd do is... In the ItemDataBound event of the Datalist, you can check th question_no column of every row, make a query to the database for the options, and bind the results to the radiobuttonlist. Another option could be... have all the questions / options in datatables in a dataset, and again in the ItemDataBound event of each item in the DataList, make a DataView of the options of the specific question, and bind them to the RadioButtonList. I hope this makes sense. daniero

Debug assertions typically aren't compiled into release code, so this likely is in the DLL rather than regsvr32.exe. As well, olefact.cpp is an MFC file, so likely not part of regsvr32.exe. Try running the whole thing under the debugger so that you can break when the assertion trips and look at the call stack. Brad
