Hi, I'm using the Silverlight MapPrinting example (with a couple of mods). When panning and zooming in on an area I get a mysterious crash which I can't debug. Running the process (without debuging) gives this error message:
Microsoft JScript runtime error: Unhandled Error in Silverlight Application Value was either too large or too small for an Int32. at System.Convert.ToInt32(Double value) at System.Windows.PresentationFrameworkCollection`1.get_CountImpl() at System.Windows.PresentationFrameworkCollection`1.GetItemDependencyObject(Int32 index) at System.Windows.Controls.UIElementCollection.GetItemImplSkipMethodPack(Int32 index) at System.Windows.PresentationFrameworkCollection`1.CollectionEnum`1.get_Current() at ESRI.ArcGIS.Client.TiledLayer.getProgress() at ESRI.ArcGIS.Client.TiledLayer.bmi_DownloadProgress(Object sender, DownloadProgressEventArgs e, ImageTileInfo data, EventHandler`1 onProgressEventHandler) at ESRI.ArcGIS.Client.TiledLayer.<>c__DisplayClass8.<addTile>b__5(Object sender, DownloadProgressEventArgs e) at MS.Internal.CoreInvokeHandler.InvokeEventHandler(Int32 typeIndex, Delegate handlerDelegate, Object sender, Object args) at MS.Internal.JoltHelper.FireEvent(IntPtr unmanagedObj, IntPtr unmanagedObjArgs, Int32 argsTypeIndex, Int32 actualArgsTypeIndex, String eventName)
I understand that a number was "too large or too small for an Int32" and that this may have come from "ESRI.ArcGIS.Client.TiledLayer.getProgress()". Does anyone have any suggestions as to how I should avoid or catch this?
It occurs when heavily zooming in and out and panning. A variation on the error just occurred:
Microsoft JScript runtime error: Unhandled Error in Silverlight Application Code: 4004 Category: ManagedRuntimeError Message: System.OverflowException: Value was either too large or too small for an Int32. at System.Convert.ToInt32(Double value) at System.Windows.PresentationFrameworkCollection`1.get_CountImpl() at System.Windows.PresentationFrameworkCollection`1.CollectionEnum`1.MoveNext() at ESRI.ArcGIS.Client.LayerCanvas.ArrangeOverride(Size finalSize) at System.Windows.FrameworkElement.ArrangeOverride(IntPtr nativeTarget, Single inWidth, Single inHeight, Single& outWidth, Single& outHeight)
If you mail me at "mattpil29 at google mail dot com" I'll send my slightly altered code.
