Crystal Report 8 with Vb 6.0 [parameters screen]

Hi,
I m using crystal in vb 60. and showing all the reports from a folder in the list and when user double click any report it ask for parameter which i fine

but if user click on the cancel button on paramter screen then it should exit but still it open the crystal report with blank page.

How i can stop this if user click on cancel button or can i can hide the cancel button on the parameter screen?
