How to set a report datasource in VB.NET using CR8.5 installed DLL?

I have CR 8.5 Developer Edition installed in my PC. I'm using CRAXDRT.dll specifically in creating my report at runtime. The only thing that gets me stuck is setdatasource parameter. it gives an error, "invalid index", with error code -2147352565.

I'm limited on using VB.NET 2005 and Crystal Reports 8.5.

Thanks in adv.! :)
