A simple model should suffice as shown below: Use the Iterate Workspace to return File GeoDatabases and tick on recursive if you want drill down into the sub-folders. You would then use inline substitution to ensure a unique file name for the Output file. If you want to do this in just python then look at this function here. ... View more

Hi Samuel, My solution was to give up! I was surprised no one from ESRI offered up an answer even if it was "you are an idiot you are doing it the wrong way" or  "no can't be done" I abandon the Textbox and created a dockable window which was something that I could display a textbox on and hook into. So it was a radical change from the previous interface. I think the AddIn framework is great but I came to the conclusion (which may be completely wrong) that you can't add controls that are not part of the AddIn framework as there seemed to no mechanism to declare them in the Config file.

Can you upload the full code, its difficult to answer this with just 1 line of code which is clearly ok if it ran for 100 times? ... View more

I would image the problem is that in your script tool you are not providing enough information for it to find the layer. The ApplySymbologyFromLayer tool takes a FeatureLayer as input (it says that in the help) but just giving it a name (which you did) could be interpreted as a FeatureClass, an object that does not support symbology. So by using the ListLayers approach you are actually providing the tool with a FeatureLayer object. ... View more

The following VBA code shows you how to get a handle on a raster layers renderer: Public Sub test()     ' Get document     Dim pmxd As IMxDocument     Set pmxd = ThisDocument         ' Get map     Dim pmap As IMap     Set pmap = pmxd.FocusMap         ' Get first layer (assumed to be raster)     Dim pLayer As ILayer     Set pLayer = pmap.Layer(0)         ' QI into rasterlayer     Dim pRasterLayer As IRasterLayer     Set pRasterLayer = pLayer         ' Get renderer     Dim pRasterRenderer As IRasterRenderer     Set pRasterRenderer = pRasterLayer.Renderer         ' Test renderer type and report     If TypeOf pRasterRenderer Is IRasterStretchColorRampRenderer Then        Debug.Print "stretchy!"        Dim pRasterStretchColorRampRenderer As IRasterStretchColorRampRenderer        Set pRasterStretchColorRampRenderer = pRasterRenderer        Debug.Print pRasterStretchColorRampRenderer.LabelHigh     End If End Sub ...

You've not given us much information, so I will make an assumption that because you mention "routes" you are referring to linear referencing? You would be able to snap you bus stops using this tool. ... View more

I suggest some code on the GIS SE website here. There is also a link back to a blog page on Geonet showing an example of using numpy which you could explore as an alternative approach for reordering tables. ... View more

I'm sure I have read in the T&C of the software that it states that subtle changes are made to any tool so as to make unnecessary work for you... It's the standard contractual agreement we all willingly entered into. ... View more

You do not state which version of ArcGIS you are using (you should always do that). If you are using 10.2 then you can use the Add Geometry Attribute tool to at add the centroid XY coordinates. As for the radius you could add a field and calculate it using: radius = sqrt(Area/pi) ... View more

I've just opened a 9.3 mxd in ArcGIS 10.2.2 and was able to copy and paste into a blank MXD, so not sure what your problem is? ... View more

Dan, If you are rebuilding these tools can you make them capable of sending the output to an IN_MEMORY workspace. I find this an extremely useful ability of a geoprocessing tool as I often test output to make sure I'm doing things right or its what I was expecting. Sending output to a place like IN_MEMORY which is destroyed when ArcMap closes is great as then I do not have to worry about cleaning up after myself. Duncan ... View more

What is the biggest number you are using? Data type short covers a range of -32,768 to 32,767 are you exceed this? ... View more

I would probably search with Google using a term like "GIS data Cleaning" or some equivalent. So are you saying that you would be generating 600 cropped images per month which you want someone else to geo-reference? How many months were you thinking? Who ever took on this work would need to have base maps to reference against. What country do you work in, I cannot tell as you have not filled in any of your geonet profile... ... View more
