Detect cancel in PrintDoc() call

Postby sgnirtswob » Wed Jan 21, 2009 3:07 pm

Hello,

I am using the active X version of VPE, and when issuing the PrintDoc() we can't detect a user cancelling the dialog. I know there is an event (RequestPrint) that seems ideal for this, except we are using a bespoke programming language which is unable to expose VPE events.
I am playing around with the idea of using the SetupPrinter and then force the PrintDoc(FALSE) to not show a dialog, except at the moment both are forcing the dialog to show.

I am asking at this stage if there is an alternative to the two methods above?

… and will my idea regarding SetupPrinter/PrintDoc be feasible to get working?

Many thanks in advance

When using the VPE ActiveX there is no alternative. It is a design flaw, if your programming language is not capable of handling events (which language is it?).

This should work. But during printing VPE sends an event, if the user cancels the print-progress dialog. You will not be informed about that either, if your programming language is not capable of handling events.

We are using KCML which is a bespoke programming language.
