It's for a script tool. I'm using a string parameter with a value list. Right now the value list is generated in teh script tool but could be created using validation class I guess? I have 6 string values that I'd like to set by default to True or Checked. So when the script tool is opened the multivalue string check boxes are selected. I'm not stuck on string as a type, I could easily select another data type and work with that. Using individual Boolean parameters makes the script tool extend too far (too much screen space), unless there's a way to arrange Boolean within the script tool? Thanks Jon

Hi all, is there a way to set the default values in a multivalue Parameter to True or Selected? Thanks

Setup a python script in a toolbox, then call the script using pythonaddins.GPToolDialog(toolboxname, scriptname)

Working this problem some more this morning, I thought I MUST be passing bad coordinates and pointing to a location where there is indeed have no data. I've tried several ways to manually enter the location points, still no luck though, cellvalue still returns �??noData�?? From a python IDE session rasterLayer = <map layer u'grdn35w121_13'> >>> rasterLayer.isRasterLayer True x = '213860' y = '3835693' >>> place = '%s %s' % (x,y) >>> place '213860 3835693' cellvalue = arcpy.management.GetCellValue(rasterLayer, place) >>> cellvalue <Result 'NoData'> From the screen shot there is data at these x, y points. Not sure where I'm going wrong here, the arcmap �??help�?? doesn't exactly provide much help either. [ATTACH=CONFIG]22174[/ATTACH]

Been struggling with this for a couple of days now and could use a fresh set of eyes on the problem. I'm trying to get an elevation spot value for a DEM file. When I inspect any point with the Information Tool I get a pixel value of elevation. However when I try tp pull the value using arcpy.management.GetCellValue() I always get a NoData. This is pretty generic code that was pulled form Google searches, it reports the X and Y correctly just not the pixel value. Any help would be appreciated Thanks class ToolClass10(object): """Implementation for MapSARElevation_addin.tool_1 (Tool)""" def __init__(self): self.enabled = True self.shape = "NONE" # Can set to "Line", "Circle" or "Rectangle" for interactive shape drawing and to activate the onLine/Polygon/Circle event sinks. def onMouseDown(self, x, y, button, shift): pass def onMouseDownMap(self, x, y, button, shift): mxd = arcpy.mapping.MapDocument("CURRENT") df = arcpy.mapping.ListDataFrames(mxd)[0] layers = arcpy.mapping.ListLayers(mxd, None, df) rasterlayer = None for layer in layers: if layer.isRasterLayer: rasterlayer = layer break if rasterlayer: cellvalue = arcpy.management.GetCellValue(rasterlayer, "{} {}".format(x, y)).getOutput(0) pythonaddins.MessageBox("XY: {}, {}\nCell Value: {}".format(x, y, cellvalue), "Results")

I have written an add-in with the new pythonaddins class, I want code to execute when editing is stopped AND data saved, not when editing is stopped and edits NOT saved. Here's an extract of the code, the script doesn't appear to honor the save_changes option and runs whenever editing has been stopped. Any insights would be appreciated. class ExtensionClass1(object): """Implementation for MakeMaps_addin.extension_1 (Extension)""" def __init__(self): # For performance considerations, please remove all unused methods in this class. self.enabled = True def onStopEditing(self, save_changes): try: # Local variables: Other code to execute goes here

Try looking into attribute assistant, it's part of the GIS for local government.

Perfect Wayne! I'll keep this little function in my toolbox from now on. Thanks again for all your help Jon

I'm getting a syntax error when using arcpy.SelectLayerByAttribute_management but the actual query works perfectly when running from within an attribute table and using Select By Attribute.. Thanks Wayne Jon

Guys, I'm hung up on one more of these, jeeze! querying a text field for fields that are not empty. My search string that works in the attribute table is iField = arcpy.AddFieldDelimiters(fc, "Area_Name") iQuery = iField+ " IS NOT NULL" This doesn't want to work in arcpy.SelectLayerByAttribute_management(lyr, "NEW_SELECTION", iQuery) Killin' me !

Ok I think all this was a corrupt MXD file, interesting.

‎12-19-2012

Update: This is happening with all my scripts so isn't code dependent. I've re installed SP1 for 10.1 Next is to see if the DB or mxd is corrupt

And here's my parameters code in case the bug lies here import arcpy from arcpy import env class ToolValidator(object): """Class for validating a tool's parameter values and controlling the behavior of the tool's dialog.""" def __init__(self): """Setup arcpy and the list of tool parameters.""" self.params = arcpy.GetParameterInfo() def initializeParameters(self): """Refine the properties of a tool's parameters. This method is called when the tool is opened.""" subjects = [] fc = "PLS_Subject_Information" field = "Name" cursor = arcpy.SearchCursor(fc) for i in cursor: sName = i.getValue(field) subjects.append(sName) self.params[6].filter.list = subjects self.params[6].value = subjects[0] return def updateParameters(self): """Modify the values and properties of parameters before internal validation is performed. This method is called whenever a parameter has been changed.""" def updateMessages(self): """Modify the messages created by internal validation for each tool parameter.

Thanks very much! Now I "get it" the arcpy.AddFieldDelimiters and the help from Wayne did the trick. Thanks !!

Not sure how else to say it, but after running the code below, the processing window just flashes continually and the script doesn't ever appear to end. I have to kill ArcMap process to get out of the script. I'm posting my entire code snippet below, hopefully someone can point out my error.
