Re: AccessViolationException in System.Drawing.dll

So, apparently we spoke too soon. This is still happening, though less often. The information in my original post still applies, so any thoughts on how to troubleshoot would be helpful. When I try to debug, it ultimately takes me into assembly code and it won't let me see the code unless I turn off ...

Re: AccessViolationException in System.Drawing.dll

We resolved this issue, and it was unrelated to GdPicture, so apologies for gumming up the forum. Turned out to be an issue with target architecture and memory allocation. We changed over to the 12.0.0.60 build of GdPicture at the same time we also changed a few other items. As a result we ended up ...

AccessViolationException in System.Drawing.dll

We recently moved all our machines to GDPicture 12.0.0.60 from 12.0.0.29 - This resolved a couple of issues we were having previously but now we are encountering a new issue we have never encountered before. We get an unhandled AccessViolationException in System.Drawing.dll - Attempted to read or wr...

Annotations Disappear When Window Maximized ...

We are having a strange issue with interactive text annotations visually disappearing from the GDViewer when the windows form is maximized. The program is written in VB, and there is a form that combines a viewer with a grid control and several buttons. Users will maximize the form so that it takes ...

Disabling GDViewer Swipe Functionality ...

We have implemented a drag and drop functionality to manage documents from a GDViewer control. It seems as though there is some kind of default swipe navigation that is competing with our intended functionality. It's like clicking and swiping on the viewer window changes the page, but I can't find a...

Re: Sending Image to be Viewed from php App

Thanks. For the record, C# won't directly cast a string to an int, so here's how I handled that situation: try { int id = Int32.Parse(Request.QueryString["imageid"]); GdPictureStatus status = DocuVieware1.LoadFromStream(new MemoryStream(Global.getImage(id)), true); } catch (FormatException ex) { //P...

Re: Sending Image to be Viewed from php App

Just what I needed. Thanks for the help! As a secondary question, what would be the best way to pass an image number to the page so I can dynamically grab the image stream from the DB? I have a global function that gets the stream from the DB, like so: public static Byte[] getImage(int imageID) { Sq...

Re: Loading Image from SQL DB Using GdPictureImaging

For what it's worth, I tried running it without the release method. Still didn't work.

That said, your solution works like a charm, and involves less code. Thanks for the advice!

Loading Image from SQL DB Using GdPictureImaging

I am trying to load an image into a Docuvieware Viewer more or less directly from a SQL DB image blob. We have been able to make this work in a Windows Forms desktop application using VB.NET. I figured I could use a similar strategy for our web portal, since the GdPicture12 Namespace appears to be b...

Re: Sending Image to be Viewed from php App

ANOTHER UPDATE: I was able to locate the source project for the demo page in my install directory. I am in the process of digging through the customizable viewer page. I'm wondering if my best bet is to dig into the JS API, and do all my player manipulation, such as loading the file automatically, a...

Re: Sending Image to be Viewed from php App

Okay, so no one has responded so far. I'll update the progress on this and ask another question. PROGRESS: I have my PHP app running happily on IIS, and I have also deployed the blank docuvieware web control, as in the tutorial on the same server, and all seems to be running well. QUESTION: Is the s...

Sending Image to be Viewed from php App

We have a PHP application that I maintain, and we are wanting to add the ability for clients to view images attached to their account via the web app. I have looked at various ways to do this with PHP, but our company recently bought the ultimate package for use with our desktop VB.NET applications ...
