I have a reports made by Crystal Reports with parameters, I call to the
report with a value into the parameters; How can I make that when I call to
a preview of this report, it does not request to me these parameters?
The report shows a window in order to request these parameters. Can I do
that this window does not appears?

In reports created with CR7 (I don't know if it is true for all other releases)
if you want to use a Parameter Field to pass a value to a report without being
asked to provide or confirm input, then use the following syntax:

CrystalReport1.ParameterFields(0) = "pName;Beth;TRUE"

This assigns "Beth" to the parmeter field pName without a user prompt.  If you
change TRUE to FALSE, the user will be prompted to confirm.
