comment MapInfo Calculating the number of Points that Fall within a Boundary
This is not an answer and so I will convert it to a comment on the answer to which I think it relates. You make no mention of KML in your original question so if you have a new one please post it instead of changing the scope of your question after it has been answered. The Tour should make our protocols a little clearer.

comment Computing distance from points to coastline
Would you be able to edit your question to include a picture of what you have tried to describe in words, please? The first two answers have interpreted what you wrote differently, and I am far from certain that I have interpreted it correctly.

comment Words from ArcPy Scripts Appear in Map Document?
By "place a text box" I think you are describing dragging a selection rectangle. That would make sense because it may not be easy to always see precisely the extent of the text box the text is in.

comment Creating layers using definition query for each field in ArcPy?
You have shown some code but have not told us precisely where you are stuck i.e. what happens when you run it? If it throws an error then always include that along with the code that produced it. It may be worth reviewing meta.gis.stackexchange.com/questions/3703/… to try and keep your question from being considered too broad.

You refer to a previous "thread" but supply no link to it. Can you edit that in, please?

comment Merge layer files in folders and subfolders with arcpy
I'm happy to answer specific questions, like what might be causing the error in a code snippet (and here I have gone a little beyond that), but am not keen to facilitate GIS SE being used as a code writing service. There are existing Q&As here and information in the ArcGIS Help that would provide answers to the second and third questions within your question.

If your original question needs clarification please do that via the edit button beneath it because comments may not always be read by potential answerers.

comment Writing SOAP returned values to table in file geodatabase
At the moment your question consists purely of statements. Can you place a question mark somewhere to clarify what you are asking, please? Also, you have an ArcPy tag but do not appear to be using that site-package.

Would you be able to edit your question to provide more details of what you do to see the message, and also what the precise error message you see is, please?

comment Arcmap record value is not displaying entirely
Sorry, I thought you were saying that the field values were written there via Python but I think you are saying that they are of unknown origin and first showed up when you tried to process them using Python. It may be worth editing your question to try and make that clearer.

comment Creating Stream Order
What have you tried? Where are you stuck? Please edit your question to provide more details as advised when you initially posted this as an answer to another question.

comment How to break polylines within a network by overlapping polygon at edges of polygons
I am marking this as a duplicate of that question. Something to note is that the use of the Identity tool is advocated and that needs an Advanced level license. There is no need to use that - use Intersect instead because it only needs Basic. If you are still having trouble doing this and you think the answer may be in error or inadequately described then provide a substantial edit here to let us know precisely what you have tried and where you are stuck, and it may be possible to re-open if it then appears to be a distinct question.

comment Arcmap record value is not displaying entirely
Why don't you just type 101 or 101RADIAT into that field and see if it overwrites the unwanted value? I've not tested but your co-worker's theory about a \n sounds reasonable to me. Without your question including a Python code snippet that shows how your field was populated it is hard to provide more advice than that.

comment how to download the map of some cities and use it in GeoMoose?
Italy is a country, not a city. You do not mention what you have found out from your research on GeoMOOSE and offline maps so far. I suspect that Google will be the best place to do that but we do have a few GeoMOOSE Q&As here.

comment ArcSDE Compress Issue
Welcome to GIS SE! As a new user I recommend that you take the Tour where you will see that our focussed Q&A format works best with one question per question, and you have three questions in yours. Consequently, I will place your question On Hold to give you a chance to decide which is the most important question for you to have answered first. You can then use the edit button to revise your question to focus on that.

comment getting to grips with raster data: Tutorial needed!
Unfortunately, I think this question is in the category of "Your questions should be reasonably scoped. If you can imagine an entire book that answers your question, you’re asking too much." (see help center). As a result I am going to put it On Hold as being too broad. To get it re-opened please edit it so that it perhaps focuses on a specific place where you are stuck when trying to work with raster data showing your research into that specific topic so far.

comment Remove a layer from TOC in my printed PDF?
This "answer" seems to be related to the "question" but it appears that asker Monty and answerer user45498 may be the same person. Unfortunately, I am unable to append the answer into the question. To avoid further confusion please ask to have your user accounts merged by using these instructions.

comment python application extension onCreateFeature
Would you be able to use the content of your comment to expand upon your answer that the system has flagged as being of low quality due to its brevity, please? I recommend always treating "about a paragraph" being a minimum length answer (or question).

comment Why can't I use AddField_management in ArcPy?
Please always copy code and errors in as text rather than pictures so that they can be searched for. Having a picture as well sometimes helps but when it is only a picture an opportunity for additional learnings by future visitors is lost.

comment Google Maps API v2 and Maps engine
Please be aware that you posted this to Meta GIS SE rather than the main site. I will close it here and migrate it there.
