Well, finally I could not edit the Bézier curve with the IElementEditVertices and the ISelectionTracker classes, so I have to develope my custom edit class. I have drawn every control vertex and every tangent line of the curve and then capture the mouse down position with a IHitTest class. Then, with the point and the index of the vertex, I have used a BezierMovePointFeedbackClass to help the user edit the curve. ... View more

Thanks for your answer Sean. I´m developing an application in ArcGIS Engine 9.3.1 and I have to allow the user to draw figures over maps and then modify them. The figures can be any annotation the user want to show in a map (points, polylines, polygons, text and polylines with text along it), for example a forest fire, an accident, etc. I cannot use the Editor, because it is a desktop object, but thanks to your post I realized I can use IElementVertices and ISelectionTracker. Unfortunately it doesn´t work (I don´t know why because with polylines works perfectly) with Bezier curves as my text with polyline is... My code is like this:         public override void OnClick()         {             try             {                 m_HitElement = ((IGraphicsContainerSelect)AxMapControl1.Map).SelectedElement(0);                 if (m_HitElement is IGroupElement)                 {                     m_EditVertices = (IElementEditVertices) IGroupElement)m_HitElement).get_Element(0);                 }                 else                 {                     m_EditVertices = (IElementEditVertices)m_HitElement;                 }                 m_HitElement.Activate((IDisplay)AxMapControl1.ActiveView.ScreenDisplay);                 m_EditVertices.MovingVertices = true;                 m_SelectionTracker = m_EditVertices.GetMoveVerticesSelectionTracker();                 m_SelectionTracker.Display = AxMapControl1.ActiveView.ScreenDisplay;                 m_SelectionTracker.ShowHandles = true;                 AxMapControl1.ActiveView.Refresh();             }             catch (Exception Err)             {                             }         }         public override void OnMouseUp(int Button, int Shift, int X, int Y)         {             try             {                 m_SelectionTracker.OnMouseUp(Button, Shift, X, Y);                 m_HitElement.Geometry = m_SelectionTracker.Geometry;                 AxMapControl1.ActiveView.GraphicsContainer.UpdateElement(m_HitElement);                 AxMapControl1.ActiveView.Refresh();             }             catch (Exception Err)             {                             }         } Thanks again Víctor Aparicio ...

I realized that my problem was caused because the map had not finished refreshing the annotation drawphase, so I solved it with a flag in the axMapControl OnAfterDraw ... View more

I have the same problem. When I try to export an image of the active view after a refresh, I have the COMException that says the data is not yet available. Did you solve the problem?? Thanks a lot! ... View more

I completely agree with you. ... View more

I have the same problem... I need to catch the event when layer´s symbology changes. It fires the OnViewRefresh, but I have to isolate it from other issues, like a map movement o a map re-scale. ... View more

If you're setting your own symbol for the tool then you'll need to set the ROP2 property to NotXorPen. symbol.ROP2 = esriRasterOpCode.esriROPNotXOrPen It works perfectly. Thank you very much for your help! ... View more
