Hi When I use of crystal report (sap 13) and .netframework 4 in my application(c#-VS2010) I will be faces with this error :

Could not load file or assembly 'file:///C:\Program Files\SAP BusinessObjects\Crystal Reports for .NET Framework 4.0\Common\SAP BusinessObjects Enterprise XI 4.0\win32_x86\dotnet1\crdb_adoplus.dll' or one of its dependencies. The system cannot find the file specified.

But when I choose .NetFramework 3.5 , it works fine.

Thanks very much

This has to do with your sql connection provider in the report. I remember I had something similar sometime back. The way i fixed it is:

Take a backup of your original report before you do this.

1) Open report
2) Field Explorer --> Database fields
3) Right click and select Set Datasource connection.
3) Add a New connection and Select OLE DB provider as SQL Native Client 10.0
4) replace existing connection with new one.
5) Save the report and Click Verify Database.
6) Delete old connection.

Then try.

If that doesnt fix it tell me. Infact either ways tell me.

Thanks

Solution 3

XML

Add "useLegacyV2RuntimeActivationPolicy" to the project "app.config" file as below.

   <code>
<startup useLegacyV2RuntimeActivationPolicy="true">

    <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.0"/>

    </startup>
</code>
