Locking my map to fixed extents crashes ArcMap 10 (works fine in 9.3)

NavinSushil

Hello,

Does anyone know why the following code crashes ArcMap v10?
if you attempt to view Data Frame properties after running it - bupbow!

But it works perfect in v9.3.1
also - is there a way of getting around it? I need this functionality to migrate our Production environment to v10.

Many thanks,

        public override void OnClick()
        {
            IApplication application = m_hookHelper.Hook as IApplication;
            IMxDocument mxdDoc = application.Document as IMxDocument;

            IMap map = mxdDoc.ActiveView.FocusMap;
            IGraphicsContainer graphicsContainer = mxdDoc.PageLayout as IGraphicsContainer;
            IFrameElement frameElement = graphicsContainer.FindFrame(map);
            IMapFrame mapFrame = frameElement as IMapFrame;

            // this line crashes in ArcGIS v10
            mapFrame.ExtentType = esriExtentTypeEnum.esriExtentBounds;
            // this line also crashes in ArcGIS v10
            //mapFrame.ExtentType = esriExtentTypeEnum.esriAutoExtentBounds;
        }

So, there was some code leading up to the original snippet that was the actual cause of problem.

I originally had:

            (m_frame.Map as IActiveView).Extent = extent;

which I changed to the following and it's not crashing anymore:

            (m_frame.Map as IActiveView).Extent = extent;
            m_frame.MapBounds = extent;

Thanks to Walter at support for picking this up.
