All, One of the great things about running a geo-processing tool is that it inserts information about the tool run on the dataset into the Geoprocessing history section of the metadata. This is incredibly useful for working out how a dataset was created, especially if the user who created the dataset provided no metadata (which in my experience is just about every major organisation on the planet). Another great thing about the modern ArcGIS is the in_memory workspace, this is great for storing temporary data without clogging up the hard drive and when you close ArcMap it all simply vanishes, love it! But... A FeatureClass stored in the in_memory workspace will not store any subsequent geoprocessing history. I may create a temporary dataset do some extra processing on it using geo-processing tools and then decide that it is indeed worth keeping and save out to a permanent location, but none of the geo-processing history is recorded. It would be an extremely useful improvement to an in_memory dataset to store the metadata. It would ensure a proper "paper trail" exists for a dataset.

Mike, It is not clear which tools you are trying to run. You state "Next I get the polygon.Boundary to get the polyline that encompasses the outer ring of the polygon." but IPolygon has no method Boundary? You refer to "PolylineToRaster" can I assume this is the geo-processing tool and not some function you are attempting to build? If it is then this tool takes as input a FeatureLayer not a single geometry object so a number for a field makes no sense. To use this tool you would need to store your polyline in a FeatureClass and supply the FeatureClass to the tool. Duncan

Ilya, Here is some VBA code I have used that shows a "brute force" refresh of all folder connections in the Catalog Tree. Duncan Public Sub refreshFolders() ' Get ArcCatalog Application Dim pApp As IGxApplication Set pApp = Application ' Get the Catalog Dim pGXCatalog As IGxCatalog Set pGXCatalog = pApp.Catalog ' QI Catalog into GXObject Dim pGXObject As IGxObject Set pGXObject = pGXCatalog ' QI GxObject into GxObjectContainer Dim pGxObjectContainer As IGxObjectContainer Set pGxObjectContainer = pGXObject ' Get Gxobjects as an enumerate Dim pEnumGxObject As IEnumGxObject Set pEnumGxObject = pGxObjectContainer.Children ' Cycle through objects until we find the Folder Connections, then break out of loop Dim pGxObject2 As IGxObject Set pGxObject2 = pEnumGxObject.Next Do While Not pGxObject2 Is Nothing If TypeOf pGxObject2 Is IGxFolderConnections Then Exit Do End If Set pGxObject2 = pEnumGxObject.Next Loop ' Re-point GxObjectContainer to folder connection GxObject and refresh all children GxObjects Set pGxObjectContainer = pGxObject2 Set pEnumGxObject = pGxObjectContainer.Children Set pGxObject2 = pEnumGxObject.Next Do While Not pGxObject2 Is Nothing pGxObject2.Refresh Set pGxObject2 = pEnumGxObject.Next Loop End Sub

OK obvious first question to ask: does the addin extension onLoad run when you open ArcMap and then your MXD?

Have you tried typing the word "AddIn" into the ArcGIS.COM Gallery section? Make sure you set the search box to search for tools.

You can get desktop scanning electron microscopes now. Although I guess one would have to smash the monitor up and place bits of it into the scanner and then you'll be limited to the pixel resolution of the monitor...so.... your electron microscope idea won't work 😉

An alternate approach is to call the existing Select geoprocessing tool, this will honor selections. Search the forum for IGeoProcessor to find out how to call existing geoprocessing tools from within VB .net.

Kevin, You will need to do some pre-processing of the text in the text box. Firstly is stID always going to be part of what is pasted into the text box? If so that needs to be stripped out. I notice that your codes are a constant 11 characters long is this always the case? You would use the following functions to manipulate the text. dim s,r,c as String dim n as Integer Let s = "StIDWC0000-0000WC0000-0001XX0022-0022" [TABLE="class: grid"]Len(string)Gives you the length of the stringlet n = len(s) Right(string,length)Returns the string from the rightlet r = Right(s,n-4)Mid(String,start,length)Returns the string starting at startlet c= Mid(r, 1, 11) [/TABLE] So having stripped off "stid", determined the length of the string, divide that by 11 and this is the number of codes entered. Step through your string returning each code and you can build up your full query string into [StID] IN ('WC0000-0000','WC0001-0001','XX0022-0022') If you are not that familiar with string manipulation in VBA then a quick search of the internet will help.

Kevin, The "updated" code is not VBA it is VB .Net that's why it is rejected. It's to do with the brackets. Your pFeatureSelection is almost certainly failing to select anything due to the where clause of your queryfilter. You declare a string pStID but you use a variable pID, are these meant to be the same thing? A query will change its syntax based upon the source format. Fields in a personal geodatabase are enclosed in [], fields in a shapefile are enclosed in "", a file geodatabase has no delimiters (certainly in 10.2). So... your pID query string is most likely to be in the wrong format. I would go into Arcmap run the select by attribute tool from the menu and try to create a selection then study its format and apply that to your queryfilter. I would put your pActiveView.PartialRefresh... line after your pFeatureSelection.SelectFeatures... line as this would then refresh the map display after the selection so you see it. Duncan

Your comment about the IGeoprocessor2 blowing up every time, what version of ArcGIS are you using and do you have any service packs installed? By the way you need to be mentioning that in any developer based question as this information is critical. For example ESRI introduced a bug with SP1 for 10.1 if you used IDataStatistics...

Dave, If you were able to answer your own question, you should tick it as answered to let others know that a solution was found. This is helpful for the rest of us! Duncan

Caleb & Doug, Many thanks for your help. I inserted the code: import peaktool reload(peaktool) from peaktool import Peak Deleted the pyc file and refreshed the way Doug suggested and this finally allows me to edit the source code and see the changes when I next run the tool. It feels like this should be much easier if ESRI want us to python toolboxes. The good news I have been able to debug the tool too! 😄

Caleb, Thanks, by deleting the pyc file my tweaks to the source code appeared. BUT! Subsequent tweaks to the source code would not be applied. So I went back into file manager, but there was no pyc file to delete! Only when I closed down ArcMap and opened it again would the pyc file appear (which would have my latest changes to it). Surely this is not the development workflow that ESRI intended? Whilst Caleb's solution is an appreciated clunky work around I still would like to know how one reloads a module as indicated in the desktop help? Could someone show how to reload the module that is importing in the format of "from peaktool import Peak"? Duncan

Python Gurus, I have downloaded the Spatial Analyst Supplemental Tools which is a Python Toolbox and there appears to be a bug in the Peak tool. I know a little bit of Python and thought I would have a crack at debugging it, primarily to teach myself how to use a Python toolbox. I am use to creating python script tools but not a Python toolbox. Anyway every time I tweak the code in the Peak tool and try to run it, it's as if the tool has been cached and none of my tweaks run. I looked at help and found this page and in the tip section it talks about imported modules needing reloading. I think this is my problem none of my changes are being refreshed. But the import statement is "from peaktool import Peak". If I type reload(peaktool) it says "name 'peaktool' is not defined". So the help page gives advice but does not explicity show you how to do it! So my question is how do you reload a module when the importing of it is in the format of "from peaktool import Peak" and where would one put the reload statement in the code? Below is the Python toolbox code. import sys import os import arcpy myScripts = os.path.join(os.path.dirname(__file__), "Scripts") sys.path.append(myScripts) from dendrogrampdf import CreateDendrogram from viewshedalongpath import ViewshedAlongPath from maxelevation import MaximumUpstreamElevation from drawsig import DrawSignatures from filledcontours import FilledContours from peaktool import Peak from eraserastervalues import EraseRasterValues from zonalstatisticsastable02 import ZonalStatisticsAsTable02 from tabulatearea02 import TabulateArea02 class Toolbox(object): def __init__(self): """Define the toolbox (the name of the toolbox is the name of the .pyt file).""" self.label = "Spatial Analyst Supplemental Tools" self.alias = "sas" # List of tool classes associated with this toolbox self.tools = [CreateDendrogram, DrawSignatures, ViewshedAlongPath,MaximumUpstreamElevation, FilledContours, Peak, EraseRasterValues,ZonalStatisticsAsTable02,TabulateArea02]‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍‍ Peak is a Class in the peaktools module.
