comment How to do Math within ArcMap Dynamic Text?
You can just create a field in the attribute table and use the field calculator. ESRI Help Files

comment Extracting polygons along a border
You'd run in in the Python window of ArcMap, but as I said it's not a complete solution. It's highly likely you'd need to have some scripting knowledge to debug / manipulate the script to do exactly what you're looking for. I didn't supply the field name that contains the state, nor did I include the path to your counties shapefile / feature class.

Haven't tested it, but it gives you the major jist.

comment Extracting polygons along a border
What's your means of measurement tho? As the crow flies, or travel based on actual roads?

comment Extracting polygons along a border
Is there a reason you're isolating line segments or is that just a means of knowing which counties share a border?

comment Which topics are fundamental for ArcGIS?
+1 - I understand the necessity to learn a piece of software, but it essentially boils down to pushing buttons. What you really need to know are the geographic concepts behind the buttons so you know which ones to push.

comment Why would a perfectly usable raster mosaic produce an unusable clipped raster?
That could be the issue that's a heck of a lot of data.

comment Why would a perfectly usable raster mosaic produce an unusable clipped raster?
Just to clarify -- you're using 2 DEM tiles? I was using quite a few, which led me to believe it may be a memory issue. That's not something I'd expect with 2 tiles tho.

comment How do I use python to batch process the reprojection of a group of shapefiles?
Just a note: most geoprocessing tasks in the gp toolbox offer a 'batch' mode if you right click them. In this instance there is already a script tool included for batch reproject.

comment Maps API that look “fancy”
There are a lot of great OSM tiles out there, don't feel you have to get bogged down with Google's offerings.

comment How to programmatically work with featureclasses from multiple geodatabases?
You could create a python list with the pathname for each gdb (workspaceList = ["C:/xxx", "C:/yyy", "C:/zzz"]). When you loop through the features within a gdb you could add an identifier to the filename that references the current workspace.

comment How to remove decimal places from currency formatting in ArcGIS?
+1 it seems like all you're after is the dollar sign -- a Label Expression is the way to go.

comment Assign symbology to multiple layers in one operation?
You could make a really simple script tool using applySymbologyFromLayer. All you'd have to do is drag and drop the layers into the dialog box.

comment How can I use a variable to specify which field to update with arcpy.UpdateCursor?
I would try debugging by printing your variable out. Since the variable only stores the string row.FieldName I can't imagine why it wouldn't work -- maybe there's a simple error that you didn't catch? In any case go with what works!

comment Why do i get an input error no module named arcpy when i try and import it into pythonwin?
Sounds like the arcpy module isn't saved to your PYTHONPATH or sys.path. Does it work within ArcMap's Python Window?

comment Using newly created features in the next part of a python script
Just a suggestion, it's generally good practice to avoid spaces and special characters with naming conventions (your gdb name).

comment How to iterate throught fields names in a table and change row values?
Why not just do this in field calculator? You could use the same snippet in each field and skip modelbuilder all together.

comment How do I format SQL queries for use in Arcpy?
I find it helpful to build the query step by step; this is especially useful when you're dealing with values stored as variables. It looks confusing at first, but you can always use a print statement to see how it turns out: whereClause = '"' + fieldName + '" = ' + "'" + fieldValue + "'"

comment Need a spatial database that can be used by QGIS and R
Spatialite = No server configuration! You can copy your database and send it to someone without having to connect anyone to a server.

comment How to connect a dbo database through the add database server in ArcCatalog?
All things considered, I think it's more likely that the configuration is wrong. I'm not sure the full extent of the differences between the full version and express, but I was under the impression it had to do with data storage capacity (Express is limited to 10GB).
