RE: More Webservice issues..

Hi Schneider,

From your description, in your ASP.NET webservice application, you always
get the following error when try building the project, correct?

" The type 'VPMEventViewer Util.DataTransf erObject' exists in
both........... ."

Based on my experience, this error is often caused by some certain types
has been duplicated in multiple places. For your scenario, the error
message indicate that some types are duplicated in the following two
assemblies:

VpmEventViewerS erver.DLL

SR.Matrix.VpmEv entViewer.Serve r.DLL

Have you checked how are those two ones generated? is one of them
statically referenced from another project(in the private "bin" dir)? Or is
one of the assembly generated by dynamic page content or App_code source?

Also, if the project is a bit too large or complex, I suggest you creating
a new one and remove some unrelated pages or sources to repro the problem
and then concencrate on the simplified project.

Sincerely,

Steven Cheng

Re: More Webservice issues..

I renamed a project, and the WS was referencing the old copy of the dll.

Re: More Webservice issues..

"Custom objects" is fine. What I was suggesting not to do is to attempt to
replace the proxy classes created by the web reference with the server
classes. They are not meant to be the same classes.

Re: More Webservice issues..

Yes, I agree with that.

Dynamically created, and a lot of the times incorrectly. Sometimes you must
completely remove the web referenceand re-add to fix problems...
