Using calls like wpview_pdfWorkbenchLoadFromStream and wpview_pdfWorkbenchSaveToStream is there a way to get the failure messages if the call returns false?
If I pass that call an encrypted pdf but don’t supply the password I can see an exception that has a descriptive message if I have a debugger attached but how can I let the user know that message?
The two references to Command in my code were CommandStrEx but otherwise the same. When I changed the code to what was suggested the problem went away.
When I use the command PdfViewer.WriteBitmap(i, wpBMP_RGB, '', MemStream, 100); compiled in a 64 bit app there is an access violation raised from the WPViewPDF3 unit. This access violation does not occur if the same app is compiled and ran as a 32 bit app. PDFViewer is a TWPViewPDF and MemStream is a TMemoryStream. This has been tried on version 4.8.5 and 4.8.3.
