Preventing a document from closing in BeforeCloseDoc event

[DanielG]

Hello,

I am trying to cancelling the closing of a document within Notifications.BeforeCloseDoc in OnEvent, but I can't seem to figure it out.

I've tried running calling SetProperty on Notifications.BeforeCloseDoc.Cancel, passing in a value of 1, but the document still closes.

I also tried setting DataOut of OnEvent to 1, but that doesn't work either.

How do I prevent a document from closing in the BeforeCloseDoc event?

Hi, Daniel.

I've tried running calling SetProperty on Notifications.BeforeCloseDoc.Cancel, passing in a value of 1, but the document still closes.

Please be sure that you changed the "Cancel" property inside your OnEvent procedure:

Code: Select all

youreventhandler OnEven(type, name...)
{
     if ((type == PXCVA_OnNamedNotify) AND (name == "Notifications.BeforeCloseDoc"))
     {
           int docID = 0; 
           pdfViewer.GetProperty(name + ".DocID", out docID);
           if (ConditionToPreventCloseDoc(docID))
           {
                pdfViewer.GetProperty(name + ".Cancel", 1);
           }
     } 
}

Thanks for the information. I believe the method used should be SetProperty (not GetProperty). When I use SetProperty, it works.

Sure, the SetProperty instead of GetProperty must be used, sorry for my auto-mistake.
