Form front for Crystal Reports 2011 to pass in parameters

Hi all,

I had hoped to build a simple VB6 front to allow the user to pass parameters to a Crystal Report, facilitate exporting/email reports, alter the sort order etc. However, I am working with Crystal 2011 and have learned that the crviewer.dll was retired in Crystal XI. What can I use instead to allow a user to run reports?

Thanking you in advance,
Imelda.
