Very Nasty Exception!

Hi,

Has anybody encounter this exception before?

Unhandled Exception: System.Runtime.InteropServices.ExternalException: A generic
 error occurred in GDI+.
   at System.Drawing.Imaging.Metafile..ctor(Stream stream, IntPtr referenceHdc,
Rectangle frameRect, MetafileFrameUnit frameUnit, EmfType type, String descripti
on)
   at System.Drawing.Imaging.Metafile..ctor(Stream stream, IntPtr referenceHdc, Rectangle frameRect, MetafileFrameUnit frameUnit, EmfType type)

   at CADImport.CADImage.Draw(Graphics e, RectangleF Rect)
   ... (removed irrelevant stacktrace) ...
   ... (removed irrelevant stacktrace) ...

I can't really pinpoint the path to reproduce it, but I know

<ul>
<li>I turn off the visibility of certain layers in my CAD file via CADImage.SetLayerVisible,</li>
<li>Call CADImage.RotToView to rotate to certain view</li>
<li>Recalculate all the width and height via CADImage.GetExtents(); </li>
</ul>

Any ideas and solutions on this? Thanks!

Hello Thomas,

Would you please give us a code which performs three steps described in you post. Also, would you please send us your file to supprt@cadsofttools.com, if AV arises just with it?
