Hello,

 

I am using Nevron charts (Nevron 2009 Vol 1 VS2008) in my application.  Nowadays the application crashes due to “ArgumentException”. I tried to handle the exception in my code (i.e. catch(ArgumentException)), but unsuccessful.

 

Following are the additional information about the exception:

 

DATA: {System.Collections.ListDictionaryInternal}

MESSAGE: Parameter is not valid.

STACK TRACE:

  at System.Drawing.Graphics.get_PageUnit()

   at Nevron.GraphicsCore.lII11llI1.Attach(Graphics graphics, NResolution resolution)

   at Nevron.GraphicsCore.N2DDeviceGDI.Attach(Graphics graphics, NResolution resolution)

   at Nevron.GraphicsGL.GLBitmapRenderSurface.Activate()

   at Nevron.GraphicsGL.l1lIlI1Ill.l11lll1(Boolean l1I11l1l1l)

   at Nevron.GraphicsGL.l1lIlI1Ill.ClearDeviceSpecificResources()

   at Nevron.GraphicsGL.l1lIlI1Ill.Dispose()

   at Nevron.Chart.NChartRenderingContext3D.Dispose(Boolean disposing)

   at Nevron.Chart.NChartRenderingContext.Finalize()

 

Is there any solution, like need to upgrade to new version or ... ? Please do let me know.

 

Warm Regards,

Sachin

Hi Sachin,

This problem is fixed in later versions of the control. You can try to call the Dispose method of the control explicitly to workaround the problem.
