Crystal Report SP26 SetDataSource() Method failed in computers of clients in Visual Studio 2019

Question

​I'm working on Visual Studio 2019 and Crystal Report Service Pack 26. My code read data into ADO.NET dataset and I set those datases as datasourse of my reports. something like this in Visual Basic.Net:

    Dim ds1 As New DataSet1()

    Dim myRep As New CrystalReport1
    taAccArticleFields_TBL.Fill(ds1.AccArticleFields_TBL)
    myRep.SetDataSource(ds1)
    crvReport.ReportSource = myRep

When I run program through VS all is good and reports show without error. But when I want to run my program on another computer which only has CR26 runtime installed, it gives an error on calling SetDataSource method for report as below:

System.Runtime.InteropServices.COMException (0x800002CD): Error in File temp_04020c6d-5b84-40d9-8558-bf87b6d5e554 4840_5464_{1C1D3ACF-9F25-45E2-B0EE-BB77F1DDA6B6}.rpt: Failed to load database information. 
at CrystalDecisions.ReportAppServer.Controllers.DatabaseControllerClass.ReplaceConnection(Object oldConnection, Object newConnection, Object parameterFields, Object crDBOptionUseDefault) 
at CrystalDecisions.CrystalReports.Engine.Table.SetDataSource(Object val, Type type) 
at CrystalDecisions.CrystalReports.Engine.ReportDocument.SetDataSourceInternal(Object val, Type type)

I encounter this with any program I write. Does anyone have idea to solve this?

Thanks to @Julie I found missing file need to run ADO.Net report using Crystal Report SP26. Unfortunately, When you install SP26 run-time it doesn't copy crdb_adoplus.dll file which need to Crystal Report to load data from ADO.Net dataset.

Here is the solution:

• In 32bit operating systems: you have to copy crdb_adoplus.dll file from developer computer to client machine from following folder:

  C:\Program Files (x86)\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win32_x86

• In 64bit operating systems: you have to copy crdb_adoplus.dll file from developer computer to client machine from following folder:

  C:\Program Files (x86)\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win64_x64

  And it work correctly. I hope SAP resolve this problem in the future service pack.

Answer 2

Please check in the previous article, witch may provide you with a solution:

1.Copy the file crdb_filesystem.dll from the development computer to the client computer

2.CRdb_filesystem.dll is in the following directory on the development computer: C:\Program Files (x86)\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win32_x86

Answer 3

I was experiencing the same issue and found that by repairing the program in Windows 'Programs and Features' it automatically fixed the problem without the need to even restart the machine!

The idea came from the a discussion on a SAP answers page (https://answers.sap.com/questions/12937477/sp26-and-installation.html) where it was said that -

"the only thing that will help is to reinstall or repair."

It seems to be correct, I just wish I hadn't wasted ages trying to find an answer!

Repairing Sap Crystal Report does not work in my case. I've tried all solutions in sap.com, but only copying file manually work for me. – Danieledaniell

Answer 4

I had this issue with Visual Studio 2022 and Crystal Reports 13 SP36. After a repair of the runtime the problems where gone.
