Exporting Crystal Report into PDF freeze - Vb.Net2

问题:

I have an application developed with Vb.Net 2003 and using Crystal report 11 used to preview many statistical reports.

I always preview any report successfully, but when exporting some of the reports (not all) into pdf using the built-in export functionality in the report viewer control, the application freezes forever.

So, I need to know if there is any report object (textobject, Picture, Chart, line, box, etc..) that might not be able to be exported into pdf, and I think this type of object is only found in some of my reports and that`s why I face this problem only with some of the reports and not all of them.

please can I have a little help over here...

Please advise...

Thanks in advance....

The most common reason this happens is that not all the variables you use in the report are filled. So make sure of that. Otherwise you should get an error on the object you use. Do you get an error on exporting?
