A VB.NET windows application uses Crystal Reports Developer Edition 9 and Microsoft Visual Studio .NET (VS .NET) 2003 (assembly version 9.2.3300) as the reporting and development tool.
When connecting to an ADO.NET dataset and refreshing the report, the following error message appears:
"Error in file C:\DOCUME~1\rolfd\LOKALA~1\temp_afc718a6-e952-4d7d-8526-8812-96d81eeb.rpt:The request could not be submitted for background processing."
Why does this error message appear?
This error message appears because Crystal Reports (version 9.2.2.x) Developer Edition for VS .NET 2003 does not include Crdb_adoplus.dll.
To obtain Crdb_adoplus.dll, download the following file:
" cr90dbexwin_en.zip (for Crystal Reports 9.0) can be downloaded at:
This file will install Crdb_adoplus.dll to your computer (but only if you have an earlier copy of Crdb_adoplus.dll in the "C:\Program Files\Common Files\Crystal Decisions\2.0\bin" folder).
If you do not have an earlier copy of Crdb_adoplus.dll in the "C:\Program Files\Common Files\Crystal Decisions\2.0\bin" folder, you can find a copy of Crdb_adoplus.dll in the "C:\Program Files\Common Files\Crystal Decisions\1.0\Bin\" folder.
Make a copy of the crdb_adoplus.dll from the 1.0\bin folder and copy it into the 2.0\bin folder, then run the cr90dbexwin_en.xxxx.exe update.
