| Author | Forum: PowerWEB Zoom for ASP.NET Topic: Dart.PowerWEB.Zoom.Zoom.RenderEndTag() leads to ArgumentNullException |
| Tomscarb From: Chicago, IL USA Posts: 2 Member Since: 08/09/10 |
posted August 9, 2010 11:01 PM I just installed the latest version of the PowerWEB Zoom component (1.0.5.5) and now the call to System.Web.UI.Control.Render(HtmlTextWriter), which calls Dart.PowerWEB.Zoom.Zoom.RenderEndTag(), leads to an ArgumentNullException at the call to System.Drawing.Image.Save. The message is "Value cannot be null. Parameter name: encoder". Any help would be greatly appreciated. I can provide sample code and the stack trace of the error upon request. Thanks in advance for your help. |

posted August 17, 2010 4:49 PM Ken, Thank you again for responding to my post. I was able to trace the root cause of this issue to logic within our application outside the scope of PowerWEB.Zoom. Once I corrected this, upgraded to the latest PowerWEB Zoom DLL (v1.0.5.5), and also followed the configuration steps for Windows7/IIS7 workstatiosn outlined in post http://support.dart.com/postings?topicid=7685, the error was corrected. Thanks again, Tom |
