comment Add grid reference from excel to arcmap 10.1
In addition to what Martin suggested, you can also convert your Excel table to another format such as dbf, csv, txt. The Add X/Y Table tool supports numerous formats other than Excel. Just make sure to double check your table formatting. ArcGIS can be picky about that.

I would say you have something wrong with your install, or settings somewhere. What you are experiencing sounds like a bug. If you have the driver installed or Microsoft Office 2007+, ArcGIS should have no problems seeing Excel files.

Convert your excel table to csv or some other text file. Also, are you saying you can't even see Excel tables in ArcCatalog?

comment Add grid reference from excel to arcmap 10.1
Are you just trying to add the Excel spreadsheet as a table in ArcMap? Or do you want to create points, based on coordinates that you have in your Excel spreadsheet? ArcMap supports both xls and xlsx extensions, since at least version 9.3.1.

comment How to create tile images for tiled maps using ArcGIS Online?
Generally, map tiling is done with ArcGIS Server and your own server machine to hold all the cached images. Having Esri's ArcGIS Online cloud storage hold your cached images could be prohibitive if your rasters are fairly large. That being said, after you have created a feature service in ArcGIS Online, you can publish it as a tiled service later.

comment Mirror two data frames
One method that isn't fully dynamic, is to use a Viewer Window. You could open a viewer on one data frame and zoom around. Then just choose zoom map to viewer to get the other data frame at the same extent. This works alright if the viewer window data frame is only being used for a reference. It also works handy if you have multiple monitors because you can place your viewer window on another screen.

comment Mirror two data frames
Based on the question, and the possible duplicate Dan C mentioned, I would say you are stuck with only matching extents and only being able to change the extent in the parent data frame. What's your use case for needing to be able to pan/zoom in both data frames?

Are you looking for this to work dynamically, or is the end result a printed/exported map?

comment Remove duplicated items in Arc attribute table?
If you don't have an Advanced license, you can play around with the Summarize tool to find duplicates. It does require some scripting or manual work to remove them however.

comment Displaying Trees in Arc Scene
So, when you put this shapefile in ArcScene, does it automatically use the elevations in the Z column for initial placement? After that, you want all points raised 20 ft?

comment How to get Listfields from Autocad DWG?
I think you may have to convert your DWG to a Feature Class in order to access that information. ArcMap has limited functionality with DWGs.

comment How to cartographically represent water flow?
The Stream Order tool in ArcGIS allows you to choose the Strahler or Shreve method for calculating order. I tend to agree for this particular case that the Shreve method may produce better results.

comment Exporting .jpg files from data driven pages in Arcmap
It is generally considered good practice to delete variables at the end of a script, so they aren't left floating around during that Python instance. One situation where it might matter is if you use the same variable (e.g. mxd) later in the same script, or in another script in the same Python instance.

comment How to copy layers between MXD's with arcpy?
If you already have the mxds open in ArcMap, it may work just as well to just drag and drop layers among the mxds. With Python, you don't even have to have them all open. Just a thought.

Are you wanting to setup user logins or app logins for your application? Also, does your application use OAuth 2-based APIs? Discussion Link: resources.arcgis.com/en/help/arcgis-rest-api/index.html#//…

comment Stereo Analyst & ArcGIS 10.1 - volume calculation
Do you have the 3D Analyst Extension for ArcGIS? You can create a TIN from your polygon layer to calculate volumes. Your polygon needs to be in a projected coordinate system though.

comment Use updatcursor to replace values in multiple fields
So, what is the script doing? What errors does it throw? Do you run it outside of ArcMap, or in the Python window?
