Do you have a date/time field? You will want to first make an event layer, then export that to feature class. Then, if you have your time field, you could use the time slider to show the data at whatever interval you want. ... View more

Annotation feature classes can be described, but it is that default subclass that is messing you up. I would try something like this instead: for lyr in arcpy.mapping.ListLayers(mxd):     if lyr.isFeatureLayer:         x = arcpy.Describe(lyr) It talks about this in the third paragraph under the Discussion section in the Layer (arcpy.mapping) help page. ...

Michael- If you run it in task scheduler, it will open with whatever the file association is, so it is possible that it is opening with the 64 bit version of Python. Just to be safe, it is a good idea to write a batch file that points to the 32 bit version of Python and then runs your script in that version. -Luke ... View more

Unfortunately, if you are talking about NIM006938 (which is referenced in that KB), then it is not fixed. The reason being is that it is a limitation of the Windows GDI graphics engine we use. ... View more

Out of curiosity, if you put the add in in C:\Program Files (x86)\ArcGIS\Desktop10.1\bin\Addins and install it from there, does it work? I recently saw a case where this worked but haven't been able to come up with a reason yet. ... View more

The reason it worked when I had it in a function is because the variables were automatically deleted once the code in the function completed successfully. Since I was able to reproduce the issue, I logged the following bug for this: NIM089529: The data access arcpy cursors do not release locks when using with statement. -Luke ... View more

Interesting. So here is what I found. The IDE does not make a difference. When I run it and it gets rid of the locks, I use the following syntax: import arcpy def main():     fc = r"C:\TestData\500ft_Grid.shp"     fields = ["*"]     with arcpy.da.SearchCursor(fc, fields) as cursor:         for row in cursor:             print(row) if __name__ == '__main__':     main() When I take it out of a function and just do the following, the sr lock remains: fc = r"C:\TestData\500ft_Grid.shp" fields = ["*"] with arcpy.da.SearchCursor(fc, fields) as cursor:     for row in cursor:         print(row) I'll have to get back to you with more information.

Yes, I was viewing the locks through Windows Explorer as well... I am at 10.1 SP1 with Windows 7 64 bit as well. I ran it through PyScipter, so I will test it in PythonWin and let you know. ... View more

Oh, sorry I didn't understand correctly. Something like this should do the trick: def count(a,b,c,d,e):     x = 0     if len(str(a)) != 0 and str(a) != "None":         x +=1     if len(str(b)) != 0 and str(b) != "None":         x +=1     if len(str(c)) != 0 and str(c) != "None":         x += 1     if len(str(d)) != 0 and str(d) != "None":         x += 1     if len(str(e)) != 0 and str(e) != "None":         x += 1     return str(x) And the bottom should be: count( !field1!, !field2!, !field3!, !field4!, !field5!) ...

If it is showing up as undefined and you know the correct coordinate system, use the Define Projection tool to set the correct cs. ... View more

I tested this with a few shapefiles and it releases all of the locks for me. I am at 10.1 Service Pack 1, Windows 7 64 bit. What is your set up? Perhaps the issue is specific to a different configuration. Otherwise, could you try this on a co-worker's machine and have another user log into your machine to see if the issue persists? ...

I would use the Calculate Field tool. Use Python as the parser, and set the pre-logic script code to something like: [PHP]def count(a, b, c, d):     e= str(a) + str(b) + str(c) + str(d)     return len(e)[/PHP] The bottom should just be: [PHP]count(!Field1!, !Field2!, !Field3!, !Field4!)[/PHP] This will feed in these 4 fields to the function, concatenate all of the strings together, then grab the length of the string. ...

I think these might be guides in your layout. The page layout help talks about them a bit. Try right clicking on the ruler on the left side of your layout and selecting Clear All Guides. Not positive, but would be worth a try. ... View more
