Hi Dorin,

Thank you for your reply. What code did you look at to design your custom preview form? XSOURCE for ReportOutput.app/ReportPreview.app and/or ReportListener.vcx code, MSDN code, etc?

I'm curious how you were able to figure out the appropriate properties and methods to reference in your custom solution?

Do you have a screen shot of your custom viewer?
