When I open the CustomerMaintenance.vb form in the SecuritySample and even after rebuilding the solution, I get the following error:



One or more errors encountered while loading the designer. The errors are listed below. Some errors can be fixed by rebuilding your project, while others may require code changes.



Could not find type 'SecuritySample.CustomersBO'. Please make sure that the assembly that contains this type is referenced. If this type is a part of your development project, make sure that the project has been successfully built.

Hi Jerry.

I've opened the Secuity Sample here to test and got the same error. But then I asked to REbuild Solution and everything worked fine.

This is a connection issue.  If you are trying to run the samples, then you need to point your connection to the server that has the StrataFrameSample database.  The table you are trying to connect to does not have the StrataFramesample database....or....you have changed the database name and your databases does not have all of the appropriate tables within it.

Thanks Ivan, I did rebuild and still had the error. So I tried again and this time it opens ok.
