问题
I have issue in Crystal Report. I have MySQL database on one server and asp.net C# website on other server. My website shows some reports well but other reports shows following error. All Crystal Reports work well on localhost.
Error: Failed to open the connection. Failed to open the connection. ADP_ReportSR1 253736_80084_{B18FB39E-5489-4D73-ACAE-50ACE7A17E83}.rpt
回答1:
Check datasource referenced in the report.
Look at Solution: Failed to Open the Connection
The computer has to be configured to connect to the datasource referenced in the report.
Setup the system the same way as the computer used to design the reports. Install the same database drivers [...]. Give them the same name.
Look also at Crystal: Failed to open Connection and Error: Failed To Open The Connection.
