one more question as I am digging deeper into the PdfViewCtrl functionality using C# / VS 209 and WinForms. With the help of this support forum I have been able to create a WinForm containing a PdfViewCtrl and severa other controls, some of them Buttons, some others are text edit fields. We are passing a PDF file name to this windows and there is a Method we are calling which opens the PDF fgile and attaches the PDF document to the PdfViewCtrl, sets full page display and thumbnails to on.
Then this Form is being displayed by it’s by a form.ShowDialog() call. Everything seems to be fine until the form is being closed. About 2 seconds after the Dialog has been closed, the whole application crashes hard without an exception being raised. The application crash cannot be monitored by Visual Studio 2019 which we are using, it seems to happen in some process not linked to VS which nevertheless must be part of the application.
Any idea what this crash is caused by?
