I've just generated a dataset and when I build the app in the declarations
section
(i.e., dsMyData1 = New myapp.dsMyData) I get the error:

Type 'myapp.dsMyData' is not defined.

This is generated code. If I remove the myapp. portion, I can build and
run.
However, the next time I build, it re-codes the myapp. notation and
re-issues
the error message.

What is more strange, is that I can close the app. create a new one, and not
get the problem. This happens only sporadically.

Any ideas?

TIA,
Marc
