comment How to convert from UTM Zone 36N Mercator to WGS 84 degrees of lat and long?
The second part of my answer provides a method for getting decimal degrees in ArcMap. Once you add the two fields, you can calculate the LatLong for all 4000 points in one-feld-swoop using the Calculate Geometry method.

Geographic coordinate systems use lat long (decimal degrees, degree minutes seconds, etc.) Which is why you need to change from projected (feet, meters, etc.) to geographic, but you know all of this.

Make sure field type is DOUBLE if you go with the second route.

Do you have the data in ArcMap?

comment Programatically write values to ArcPad Form control box
Limit to list doesn't appear to be an option in version 10.0.3 -- when you say boiler plate code generated by ArcPad, is ArcPad composing code for you? The code you have written for "Use like this," is that the function call (I'm much more comfortable with Python compared to VBS).

comment Programatically write values to ArcPad Form control box
It's a text field, but it has a domain (there is a preset list of names contained in a drop-down menu). I figured that I wouldn't be able to insert a NEW value, but one within the domain should work. I suppose that's a good question for the script's author.

comment Store global variables in ArcPad that store user information
Have you had any luck implementing the log-in form? I've gotten to the point where I can 'Alert' the user name back in a message box, but all my attempts to write the name in a control box have failed.

comment Adding a boolean yes/no field in Arcgis
Using the attribute domain will restrict user input to what you define ahead of time (in a handy pull-down menu). If you ever need to access it in code, you don't have to account for Y vs. Yes vs. yes vs. y.

comment Select Layer by Location Produces Empty Output in Python
I'm not sure if this would do anything either but the from arcpy import env statement might only allow you to access env settings. Try getting rid of that statement and changing your workspace to arcpy.env.workspace = "C:\\location". Are you getting any error message?

comment Select Layer by Location Produces Empty Output in Python
When you call arcpy.SelectLayerByLocation() you left in selection_type= too.

Please be more descriptive -- I don't follow the "at each change in county I need the column to start from 1 and progress..."

comment Add feature layer to display with in a script tool for desktop mapping 'App'
@MLowry Is that a separate call from the RefreshActiveView, which is meant to refresh both the TOC and the Map?

comment fail to create relationship class
I've done a Many-to-Many relationship, which uses a 'junction table' that links keys from tables on either end, but it only works in one direction. It seems like table-to-table may be possible, but you should expect some 'Weird' things to happen as a result.

comment Add feature layer to display with in a script tool for desktop mapping 'App'
The reason I opted for a feature layer is because you can run a SelectLayerByAttributes(inLayer, SelectionType, whereClause) followed by zoomToSelectedFeatures(). This technique is not available to .lyr files, only feature layers.

comment Best example of a GIS project gone wrong
I saw at the ESRI Fed UC that they're adding support for this sort of analysis (basing buffers on projected data) -- cool stuff.

@Dan A derived parameter will not OR cannot be added? The other types are Required and Optional. The direction is, as you can see "Output".

comment Add feature layer to display with in a script tool for desktop mapping 'App'
@blah238 I've used both the arcpy.mapping.MapDocument("CURRENT") and the arcpy.mapping.MapDocument(r'pathName') methods with the same result.

@blah238 df = arcpy.mapping.ListDataFrames(mxd, "Layers")[0]; Run Python script in process IS checked.
