Crystal reports error in SetDataSource

Question

I am having trouble in VS 2010 sap crystalreports, using c# to make a windows application.

I get the following error with the following code:

 Crysta         


        

Answer 1

 <startup useLegacyV2RuntimeActivationPolicy="true" >
    <supportedruntime version="v4.0" sku=".NETFramework,Version=v4.0" />
 </startup>

Add this code in app.config.

Answer 2

You probably need to install the crystal reports runtime files. You should be able to do a google search to find them. The error message is pretty explicit in telling you the problem is a missing .dll. Read it ;)

edit: Try locating the crdb_adoplus.dll on your machine and copying it to the application directory.

Answer 3

Try using this solution by adding the useLegacyV2RuntimeActivationPolicy attribute to your .config file

<startup useLegacyV2RuntimeActivationPolicy="true">
