Hi,

I'm having problems using a Data Access Layer in my Crystal Reports in
Visual Studio 2005.
My project has 3 combined projects: my BLL, my DAL and my PL.

If I choose my datasource in the crystal report dialogue, going through
".NET Objects"-"Default" I choose my DAL.dll in the current project.
Then I can choose my class from my DAL-class, after checking "Use
DataSet from class" I get access to my methods.

Selecting a method and pressing "Finish" gives me the error:

Crystal Reports ActiveX Designer
Logon failed.
Details:mscorlib : Exception has been thrown by target of an
invocation.

My database however doesn't require authentication, what's going on?
