CrystalReports

If somebody have god aplication on database Oracle Provider OleDb can You send me?

I've had the same problem. Maybe the problem is in fact that we are using the free version of Crystall that it only works with the ACCESS. With OleDb Provider Oracle,.. fill the dataTables theh, make the XML structur file with the same atributes name like you get from the SQL query. Then use it in tle Crystall window section "Other data sources - something like this :)" In this way you fake it, if anyone have a simplier method or solution I would be very glad if someone tell it.

I'm not 100% sure about this, but you may have to set a connection property of the crystal report viewer by code. If this is set, the viewer will not ask you for the logon information.

I use OleDb Provider Oracle Help

If u use SQL Server, try to make an XML file from the datatable and then use it in Crystall as a database structure. It works
