I maintain a Windows Forms (.Net 4.0) application which uses GdPicture.Net v18.104.22.168, specifically the GdViewer component, to display image files.
Users are reporting that our application crashes after handling a random number of images.
The Windows Event Viewer shows a System.AccessViolationException. As this originates in unmanaged code and hence bypasses all of our C# handlers and unhandled exception failsafes, we don't even get good logging. I can say however that it comes shortly after an "InternetConnectError" occurs during a gdViewer.DisplayFromHTTP() call.
I believe I have located the offending method in the GdPicture .dll disassembly - see attachment. I am also attaching a screenshot of the Event Viewer showing the text of the errors. Is there a patch for this crashing issue?
But is this the wrong place to look for info for a critical crashing issue in this paid-for commercial product?
Our version is now several years old, I find it hard to believe this bug has not been detected and fixed at this stage. I cannot find any info elsewhere on this site though.
Is there somewhere I can download older (version 6.x) releases?
Can someone from GdPicture please advise urgently - we are under pressure to address this crash.
Yes you are in the wrong forum, and GdPicture 6 is not maintained since four years.
That said, this problem is unknown and can be caused by a previous memory access violation for example.
I can suggest you to upgrade the control to the latest version 10 version, if you need more information you can contact our sales department through http://www.gdpicture.com/contact.php
Our technical team can help for urgent situation through our helpdesk platform companies owning a valid license covered by a support plan.
