We have a VB.Net Application which uses Adobe Reader 6.0 to display and print the PDF Reports. There is a report interface for the selection of report parameters and while clicking Print button, we are printing the PDF file using the PrintDialog method (ReportForm.AxPdf1.printWithDialog()). For the first time, there is no issue with that and without closing the Report Interface, if we are trying to print the same report by selecting some different option, we are getting an error message as follows: "One or more PDF documents are open inside a web browser. If you Exit Adobe Reader now, Those documents will be closed. Are you sure you want to exit?" There are two options for this either choose Exit or choose Cancel. Also got another option to block this message for the second time onwards (Checkbox with 'Do not show this message again').
We tried checking the option 'Do not show..' and Cancel button, and it is found working on most of the machines. But even after doing 'Do not show...' option, it is still showing this message.
Also we modified the Internet Options of Adobe Reader 6.0 by unchecking the 'Display PDF in Browser' option from Edit->Preferences->Internet tab.
Please help me to overcome this error message.
