Is pageNum actually the name of the field you used as the "Name Field" when you set up your DDP? getPageIDFromName (page_name) Parameter Explanation Data Type page_name A value in the index layer that corresponds to the Name field that was used to set up Data Driven Pages String Many of the Data Driven Pages properties and methods use an internal index value rather than the literal names of the pages used to create the index layer. The index values are automatically generated based on the Name and Sort fields. It may not be obvious which index value represents a specific page. The getPageIDFromName method provides a mechanism for this translation. pageID = mxd.dataDrivenPages.getPageIDFromName("HarborView") mxd.dataDrivenPages.currentPageID = pageID R_ [ATTACH=CONFIG]26820[/ATTACH] ...

Well, that definatly gets more complicated, however, if you are using 10.1, here is one way. Open your arcmap document that has the most permeatations. create the symbology you want for the values (if it doesn't exist in that layer/map, you can add value to the list, even if it isn't displayed)   Adams 1900 - red   Bruce 1985  - blue   etc... now, save that as a layer file.  in your map document, legend properties, check the box that says "Only show classes that are visible in the current map extent" and save the mxd. Now, with python, after you have your data genereated, us the updateSymbology to apply that layer file to the FC.  With the "Only show" box checked, you will only see the values/symbology for feature that show in the current layout extent, so, if a particular permeatation doesn't exist in the map, it won't display it on the legend. Of course, now that I think about it some, ESRI has not given python access to the "only show " legend box, so you would have to manually set that on your layer in all your mxd's.   Might be able to utilize a template to set this on all mxd's, would have to look into that a little. I see we can change class values, labels, etc., but I don't see any way to assign a color to a feature using python, other than with a .lyr file. If we could, there might be a way to iterate through all of them and append the classes to a list, then get the unique set, create a dictionary from that and apply it to the layer(s) you want.  however, not sure how you would control the colors anyone know if we have access to the "colors" used for unique symbology? In the first example you provide above, that changes the symbology including the DisplayField, which is not really what I want. In the second, that shows some of the Layer properties exposed in arcpy, but I am not sure how to access colors for a Unique_Value map. symbology_only - A Boolean that determines whether or not to update only the layer's symbology, or all other properties as well. If set to True, only the layer's symbology will be updated. R_ ... View more

It does not run for me at all. In fact, I set root = r'D:' and it gives me .prj files located several folders deep. In no way can I make it report the mxd's in the listed directory. If I start it out like this it will get the list of mxd's: arcpy.env.overwriteOutput = True text_elms = [] the_text_elm = None start = "D:\\" for root, dirs, files in os.walk(start):     for mapDoc in files:         if mapDoc.endswith(".mxd"):             print 'Working on ',mapDoc             path = os.path.abspath(os.path.join(root,mapDoc))             mxd = arcpy.mapping.MapDocument(path)             text_elms = arcpy.mapping.ListLayoutElements(mxd, "TEXT_ELEMENT", "Archit")[0]             the_text_elm = None             the_text_elm = text_elm have you typed print os.listdir(root) and make sure that it only reports mxd files? as mine crashes trying to set the mxd = somefileotherthan mxd (the first file in my directory) the above code "fixes" that. If you are changing for ALL text elements with name = "Archit", you don't need to iterate through the list In fact, you assign it to text_elms, then try to iterate through that as a list. Can't be done as text_elms is a list of TextElement objects, and is not iterable as is not a list (). Then, in this part, do whatever if's you need, but you have assigned the text element to text_elms variable (not the_text_elm), so that is the one you want to update: if the_text_elm:   i = the_text_elm.text.find('Archit')   new_text = the_text_elm.text[:i] + 'Historic Resources'   text_elms.text =  new_text   mxd.save() Here is modified code that is working for me, you should be able to extract what you need: import os import arcpy # Overwrite pre-existing files arcpy.env.overwriteOutput = True # Loop over MXDs folder = r'H:\myDir' arcpy.env.workspace = folder arcpy.env.overwriteOutput = True for root, dirs, files in os.walk(start):     for mapDoc in files:         if mapDoc.endswith(".mxd"):             print 'Working on ',mapDoc             path = os.path.abspath(os.path.join(root,mapDoc))             mxd = arcpy.mapping.MapDocument(path)             if arcpy.mapping.ListLayoutElements(mxd, "TEXT_ELEMENT", "Archit"):   # this keeps it from erroring out if the text element "Archit" doesn't exist...                text_elms = arcpy.mapping.ListLayoutElements(mxd, "TEXT_ELEMENT", "Archit")[0]                new_text = "test"  + ' Historic Resources'                text_elms.text =  new_text             mxd.save() Keep in mind this will walk through all sub-folders as well. Hope this gets you on the right track, R_ ... View more

Well, if value A and B are the same in all the maps, the easiest way would be to open ArcMap, load your feature class and symbolize as desired.  then, right click on the FC and save as layer file. Then, you can use UpdateLayer in python to update the symbology using the layer file you created http://resources.arcgis.com/en/help/main/10.1/index.html#/UpdateLayer/00s30000003p000000/ . If the values for A and B can differ, you can set up and create the layer file in python http://resources.arcgis.com/en/help/main/10.1/index.html#/Layer/00s300000008000000/ , then use that one to update the layer(s).

Geoff, Originally I was expecting the definition queries of the point layer would control which points were being labelled. I didn't know what the python script would disregard that control. You can set the same definition query in the SQLclause portion of the labelClass if you only want it to label features that are valid in the layer definition query. http://resources.arcgis.com/en/help/main/10.1/index.html#/LabelClass/00s30000002t000000/ R_ ...

I can't seem to be able to make it work either.  Must be related to the table view, as if I join directly to a table, it works as in my previous post. I did notice that if I copyRows to an in_memory table, then join to that it works as expected, just not with the table view. R_ ... View more

Glad it worked for you. Also, I see you gave me a point with the up arrow, would you might selecting the checkbox as answered also? Will give me credit for it and also mark it answered for people searching similar issues in the future. Thanks, R_ ... View more

This is working just fine for me.     <fields>         <field name="Shape_Area" alias="Area of Feature" visible="true">              <format precision="2" usethousandsseparator="true"/>         </field>             </fields>    Of course, if I set it to "-1" I get the default, which is a whole ton of zeros. so, with it set to -1      37,441.89976562478 Set to "2":      37,441.90 R_ Works with my other numeric fields also.  Just figured everyone can come up with a Shape_Area field to test. Though, I'm not using the description tag, so have not tested that part. Ok, just tested using the description tag.  still working as expected. ... View more

Could also just check to see if file exists, and size: import os, stat if os.path.isfile(infile):          # checks if exists, otherwise get error if checking size on non-exist file os.stat(infile)[stat.ST_SIZE]   ##  returns size of file  0L if empty else: print "file not exist" This is done pretty much instantly..

Sorry Michael, it seems I confused myself a bit. It was with indexes that I had this issue and had to work around it. For the joins, you just have to know what the name that was assigned to the join is, then it can be removed without error (just tested again in 10.1). â? If the join table was a dBASE file named MyTable.dbf, the join name would be "MyTable"; so to remove it, specify "MyTable".  â? If the join table was an INFO or Geodatabase Table named MyTable2, the Join Name would be "MyTable2"; so to remove it, specify "MyTable2".  â? The join name will not reflect the name of the table view itself, but rather the source of the table view. Therefore, if a table view is named TableView1 and points at mytable.dbf, the name of the join will be "mytable".  My joins are to table(s) in FGDB so something like: summary = "\\\\mcflight01\\MCFlightData\\rzworking\\script_baks\\wc98116\\update\\data_4_temp_services.gdb\\summary" wids_full_buffer2 = "\\\\mcflight01\\MCFlightData\\rzworking\\script_baks\\wc98116\\update\\temp.gdb\\wids_full_buffer" wastebuffers3 = "\\\\mcflight01\\MCFlightData\\rzworking\\script_baks\\wc98116\\update\\temp.gdb\\wastebuffers3" arcpy.MakeFeatureLayer_management(wids_full_buffer2, wids_buffer_Layer, "", "", "") arcpy.AddJoin_management(wids_buffer_Layer, "SITECODE", summary, "SITE_CODE", "KEEP_COMMON") arcpy.AddJoin_management(wids_buffer_Layer, "SITECODE", wastebuffers3, "wids_full_buffer_SITECODE", "KEEP_COMMON") arcpy.RemoveJoin_management(wids_buffer_Layer, "summary") arcpy.RemoveJoin_management(wids_buffer_Layer, "wastebuffers3") I can use either or both of the removes to remove thier respective joins (need to specify layer and join name).

I had a similar issue with joins that were set up on the data or mxd itself. All the joins that I added with python, I was able to remove individually by name. So, my workaround was to not have any initial joins, and create them all in the python script, then I can add/remove at will. R_ ... View more
