Hi Michael,
I think I understand now. You want to display the viewer control, but not
use a form to do so? If that's true, then you can't do it. It's like trying
to write a book without paper. The words have to be put on something so you
can read them. They can't just float in space. The viewer has to be hosted
within a form to run. However, I don't understand why having a generic form
with a generic viewer control that is passed a report object would be a
problem. I guess you are just trying to streamline things by eliminating the
form?
Re parameters, again I'm a little confused. It's perfectly feasible to
create a generic dialog box that takes input from the user and sends it to
the report object. To make the dialog box specific to the individual report
parameters, you have to loop through the parameter collection and examine
each parameter's properties to find out what type of paramter it is, its
name and its prompt message.
HTH,
Brian Bischof
