Running Server 10.1 SP1 on a Win2008R2 box. I'm trying to root out an issue we're seeing with our JSAPI base map application. The map simply has an Esri basemap and a featurelayer from our server.  The featurelayer does not load every time.  Using Firebug and IE's f12 tools I can see the response from the Query op issued when the layer is added to the map as {"error":{"code":400,"message":"Unable to complete operation.","details":[]}} It happens when I issue query requests to the service without a map too.  If I put the following simple query in my browser (happens in IE, FF, Chrome) it works every other time - http://servername:6080/arcgis/rest/services/folder/service/MapServer/0/query?where=1=1&f=pjson 1st, 3rd, 5th, etc... GET requests yield valid results { "displayFieldName": "Name", "fieldAliases": {   "Name": "Name" }, "geometryType": "esriGeometryPolygon", "spatialReference": {   "wkid": 4326,   "latestWkid": 4326 }, "fields": [   {    "name": "Name",    "type": "esriFieldTypeString",    "alias": "Name",    "length": 50   } ], "features": [   {    "attributes": {     "Name": "ALC2"    },    "geometry": {     "rings": [      [       [        -107.0837499999999,        38.841250000000059       ],       [        -107.0837499999999,        38.841250000000059       ],       .... and so on alternating requests return the same error shown above. There are no errors shown in the server logs in Manager.  I have logging set to verbose and I can see to requests/response (below, the failure has the smaller response size) FINE Aug 29, 2013 10:58:22 AM REST request successfully processed.

In ArcCatalog if you open the propreties of a RasterDataset you can edit the value of the NoData value.  On the Edit form, there's a button that says Compute (see attached).  I'm guessing this is based on the raster's pixel type & depth.  Is there a method on one of the many raster interfaces that can determine this value for you or do I need to write my own, e.g. using IRasterInfo::PixelType and switch statement?

I know I can open a GP tool using code like this -             //Opens the Clip Raster GP tool             IGPToolCommandHelper2 gpHelper = new GPToolCommandHelperClass() as IGPToolCommandHelper2;             string toolboxName = extMain.GetArcGISDir() + "ArcToolbox\\Toolboxes\\Data Management Tools.tbx";             gpHelper.SetToolByName(toolboxName, "Clip");             try             {                 gpHelper.Invoke(null);             }             catch (Exception ex)             {                 System.Diagnostics.Debug.WriteLine(ex.Message);             } but is there a way to open a tool in batch mode, similar to when you right click on a system GP tool in the Toolbox and you get 'batch' in the context menu? Thanks!  TG ... View more

I'm trying to follow the asynch pattern described in the SDK sample "Executing geoprocessing tools in the background" (online  here) but keep getting a COMException in my ToolExecuted handler when I try dequeque the next tool call ExecuteAsync. Event handlers are set in the constructor of the class -             _gp = new Geoprocessor();             _gp.ToolExecuted += new EventHandler<ToolExecutedEventArgs>(GPToolExecuted);             _gp.ToolExecuting += new EventHandler<ToolExecutingEventArgs>(GPToolExecuting); The first tool in my Queque is called in this method - internal void RunTool(Queue<GPFunction> GPFuncs)         {             //Runs a TauDEM GP tool.  Input GPFunction queue can also contain conversion & clean up GP tasks             //since TauDEM only reads/write UnCompressed TIFFs             GPFunction gpfunct = null;             try             {                 _gpfunctions = GPFuncs;                 gpfunct = _gpfunctions.Dequeue();                 _gp.OverwriteOutput = true; // gpfunct.OverwriteOutput;                 _gp.AddOutputsToMap = gpfunct.AddtoMap;                 _gp.AddToolbox(_strTauDEM + "TauDEM5Arc\\TauDEM Tools.tbx");                 if (gpfunct.Environments != null)                 {                     foreach (KeyValuePair<string, object> kvp in gpfunct.Environments)                     {                         _gp.SetEnvironmentValue(kvp.Key, kvp.Value);                     }                 }                 _gp.ExecuteAsync(gpfunct.ToolName, gpfunct.ToolParams);                             }             catch (Exception ex)             {                 System.Diagnostics.Debug.WriteLine("Error in RunTool");                 System.Diagnostics.Debug.WriteLine(ex.Message);             } } The first tool (usally CopyRaster to convert to Tif which is the only input a custom tool will take) fires and and when it completes it will go into ToolExecuted but bombs on the ExecuteAsync         private void GPToolExecuted(object sender, ToolExecutedEventArgs e)         {             //Fires when a GP tool completes (fail or success)             IGeoProcessorResult2 result = e.GPResult as IGeoProcessorResult2;             GPFunction gpfunct = null;             if (result.Status == esriJobStatus.esriJobSucceeded)             {                 System.Diagnostics.Debug.WriteLine(result.Process.ToolName.DisplayName + " completed");                 if (_gpfunctions.Count > 0)                 {                     try                     {                         gpfunct = _gpfunctions.Dequeue();                         _gp.OverwriteOutput = true;  //gpfunct.OverwriteOutput;                         _gp.AddOutputsToMap = gpfunct.AddtoMap;                         if (gpfunct.Environments != null)                         {                             foreach (KeyValuePair<string, object> kvp in gpfunct.Environments)                             {                                 _gp.SetEnvironmentValue(kvp.Key, kvp.Value);                             }                         }                         _gp.ExecuteAsync(gpfunct.ToolName, gpfunct.ToolParams);                   //throws exception here                     }                     catch (Exception ex)                     {                         System.Diagnostics.Debug.WriteLine("Error in ToolExecuted");                         System.Diagnostics.Debug.WriteLine(ex.Message);                     }                 }             }             else             {                 System.Diagnostics.Debug.WriteLine(result.Process.ToolName.DisplayName + " did something else");                 IGPMessages msgs = result.GetResultMessages();                 for (int i = 0; i < result.MessageCount; i++)                 {                     IGPMessage msg = (IGPMessage)msgs.GetMessage(i);                     System.Diagnostics.Debug.WriteLine(msg.Description);                 }             }         } If I click on the button on my form after the Exception occurs it will write my debug statements to the Output panel 2x. Anyone have an idea what I'm doing wrong & why it seems to be executing the ToolExecuted handler 2x?? Thanks, Terry ... View more
