I was able to get a list of the folders using the below code. You'd need to convert it to VB.net. ... View more

I believe that this can be done in ArcObjects via IAoInitialize, but it isn't possible out-of-the box with Python or ModelBuilder. From ModelBuilder within the UI the license is derived from the ArcGIS application used to open the model (i.e. if you open the model in ArcMap with a Basic license the model will use a Basic license). Within python there was a method in the 9.2 days called SetProduct, which could be used to set the license, but it appears that function has been deprecated by the arcpy site package. With arcpy you'd need to set the license prior to importing the arcpy site package, so it wouldn't allow you to change licenses in the middle of the tool. This is just a guess, but you may be able to get what you need to work in python if you run the various parts of your workflow on separate processes. When the new process starts you'd begin by importing the license level needed (i.e. arcinfo, arceditor, arcview, arcserver, arcenginegeodb, or arcengine) and execute your needed logic. Once the process ends and returns the license you'd begin the next process with the next needed license. This of course would be assuming that you had a concurrent use license that has the different license levels available.

I believe that your problem is a logical error. You're check to see if the value of the parameter is equal to a list instead of a value within the list (i.e. value=["PNR"] vs value = "PNR"). Maybe I can suggest an easier way to execute this. I was able to get it to work with the below logic. You'll see that I'm using a dictionary to host the list of values for each province. import arcpy 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."""     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."""     caDict = {'ATL':['NB', 'NL', 'NS'], 'ON':['ON'], 'PNR':['AB', 'MB', 'NT']}     self.params[0].filter.list = sorted(caDict.keys())     if not self.params[0].hasBeenValidated:       if caDict.has_key(self.params[0].valueAsText):         self.params[1].filter.list = caDict[self.params[0].valueAsText]            return   def updateMessages(self):     """Modify the messages created by internal validation for each tool     parameter.  This method is called after internal validation."""     return ...

Hi Yogi, I looked into this issue and I have been able to replicate it. This issue appears to be a bug because I'm able to create fields in a file geodatabase with 64 characters, as per the documentation, but the Alter Field management tool appears to be restricted to 31 characters. Defining fields in tables http://desktop.arcgis.com/en/desktop/latest/manage-data/geodatabases/design-defining-fields-in-tables.htm If you have an active support account could you send me a private message with your account information so that can attach your information to the bug I'll log for this issue? Workaround At the moment the only workaround I can see for this issue is to use the Add Field tool. Unlike the Alter Field tool, this tool will modify the order of your fields. If field order is important to you I would suggest either using python to create a new template feature class with your updated field and loading your data into this new dataset prior to overwrite the original class or create a fieldmappings object against your data, updating the information for the needed field, and then using the Feature Class to Feature Class to create a new clone of your data prior to overwriting it. ...

With python this would involve post processing (i.e. after you add features you'd need to run a script to update these values). If you wanted to execute this as you create features you would need either an editor extension (Python or ArcObjects) or a feature class extension (ArcObjects). In the editor extension you would need to listen for the on create event. An easier option may be to use the Attribute Assistant to automate this task.  You could leverage the Dynamic Table functionality within it that could automate populating your fields with the needed values.

Hi Brian, As Xander stated these commands should be searchable within our 10.3 documentation. The only thing I want to note is that you're leveraging a "Model Only" tool and exporting the model to a python script. These "Model Only" tools are intended for use in ModelBuilder only, so you will need to leverage the functions available in the python to incorporate your conditional or loop logic. For example, a replacement for the GetFieldValue tool could to utilize a cursor to parse the value from the dataset.
