I have added some columns in datatable n i want to update Database fields,so when i click "Verify Database" , a dialog titled "ADO.NET" appears and asks for a "File Path," "Class Name," and an option to "Use DataSet from Class." "Class Name" is pre-populated with the name of the .Net class that my report's data source is tied to.
At this point, I'm not sure what to fill in for "File Path." Clicking "Finish" will bring up a dialog titled "Crystal Reports ActiveX Designer" that reads: "Logon failed. Details: crdb_adoplus: To access classes in your project at design-time, please build your project first, and then try again." (note: My project has already been built).
Any body suggest me the solution.
