Neal, Excellent and thank you for sharing your solution! I would never have thought to use the parse tool. Definitely going to use that trick in future models. Duncan ... View more

Does your dataset have larger holes or are they always .5x.5? Do you want to remove ALL holes or just the small ones? ... View more

Having set the NoData value have you tried to save the raster first using ISaveAs to commit the change?  The help file says These modifications only affect the in-memory raster representation and in no way change any of the raster dataset. You can persist the modifications to a new raster datast using ISaveAs::SaveAs or IRasterBandCollection::SaveAs. Duncan ... View more

Here is some VBA code to show how you would call a model in a toolbox     ' Create workspacefactory     Dim pToolboxWorkspaceFactory As IWorkspaceFactory     Set pToolboxWorkspaceFactory = New esriGeoprocessing.ToolboxWorkspaceFactory         'Open a toolbox workspace - you need to change the path     Dim pToolboxWorkspace As IToolboxWorkspace     Set pToolboxWorkspace = pToolboxWorkspaceFactory.OpenFromFile("c:\temp", 0)         ' Connect to tool - you need to change the toolbox name and model name     Dim pGPToolBox As IGPToolbox     Set pGPToolBox = pToolboxWorkspace.OpenToolbox("myToolbox.tbx")     Dim pGPTool As IGPTool     Set pGPTool = pGPToolBox.OpenTool("mdExplodeToSingleRoutes")     ' Run tool     Dim pGPToolCommandHelper As IGPToolCommandHelper     Set pGPToolCommandHelper = New GPToolCommandHelper     pGPToolCommandHelper.SetTool pGPTool     pGPToolCommandHelper.Invoke Nothing     ' Destroy objects     Set pToolboxWorkspaceFactory = Nothing     Set pToolboxWorkspace = Nothing     Set pGPToolBox = Nothing     Set pGPTool = Nothing     Set pGPToolCommandHelper = Nothing ...

Don't know if this will help but have a look at IGPUtilities.RemoveInternalLayer Method? ... View more

This can be done simply by running the spatial join tool and making sure your join operation is ONE to MANY. No ArcObjects required what so ever. ... View more

I've not tried this, so it may not work as you intend? Why not listen out to the IEditEvents.OnSelectionChanged Event? If the selection exceeds your criteria you set a global boolean to TRUE so when the user attempts to delete the features your IEditEvents.OnDeleteFeature Event tests the boolean? If TRUE then follow some other logic? Duncan ... View more

Is there a specific reason why you are compiling under the .Net Framework 4? If I was developing simple tools I would do it under the 3.5 Framework. Have a look at this page if you want to develop in .Net Framework 4. ... View more

If the error is occurring on the line: lbox_selectedFeature.Items.Add("OID:" + f.OID); Then it may be a type conversion error as OID will return an Integer. SO in VB I would do something like: lbox_selectedFeature.Items.Add("OID:" + f.OID.ToString()) ... View more

Unless I'm missing the point, calling the Summary Statistics tool will do this in one line of code? arcpy.Statistics_analysis("Export_Output","in_memory/x",[["ID","COUNT"]],"ID") This creates a table called X in the in_memory workspace and returns a count on a field called ID. ... View more

Neal, I know exactly the problem you are describing and have never been able to find a satisfactory solution to it, other than exposing the field name you are doing the calculation on and the expression as model parameters. This way you can change then accordingly for each run of your model.  This means you run your model as a normal tool rather than going into model builder to run it. Duncan ... View more

I have never tried to dock toolbar bars in a specific order so this may be a red herring but the ICommandBar.Dock method apparently allows you to specify an optional commandbar "to be used as a location reference". Just an idea? ... View more
