I like this solution but checking the number of paramters from arcpy would be good too since it might be invoked incorrectly from command line without the arguments, the absence of args could be either user error or toolbox... ... View more

Thanks James,  This solution is pretty elegant but I gave the answer to Shaun because although satisfies the initial requirements doesn't account for the possibility that the script could be called by other esri applications such as ArcCatalog, etc.  It is possible to trap for each one but then esri can come out with new applications such pro... ...

I will be praying that it uses ArcObjects and not some new set of Objects.  But if not, it won't be the first or second or third time ESRI said "Let's make our  client developers do it all again". I suggest voicing you concern to esri.  Personally I think getting away from COM is a very good thing but esri can provide a similar API in .net with most of the same objects. ... View more

0.07 acres off sound like a rounding error.  I don't think it is the same problem. Shape.Area is usually almost meaningless.  It is the cartesian area calculated in the coordinates of the dataset as if the the world was flat.   If your dataset's spatial reference is not defined to start with, the shape.area is of unknown units, so potentially doubly meaningless.  Just think, what does the shape.area mean if the polygons are in geographic coordinates (latitude/longitude)?  It means pretty much nothing at all. If your dataset is projected with non-angular units (metres, feet, etc.) then it represents the area within the tolerance of the distortion factor (scale factor) of the projection system if your projection system is appropriate for the data and area measurements.  In that case you may end up with 0.07 discrepancies due to projection distortion. ...

This is an interesting problem but you actually have two questions, it seems to me. 1. how to determine if the high point between two point is smooth or sharp(?)  Which really depends on how you distinguish either in terms of your wave diffraction equation.  Seems like a directional slope change problem, 2nd polynomial or running slope tool twice. 2. how to do this in ArcObjects.  You really can't tackle this until you'v answered question 1. ...

A file gdb will almost always outperform an entreprise gdb.  The model is much, much simpler, you are just writing to a file on your hard drive.  As long as on-access scanner isn't killing the performance it will be much faster. For the code side, I would consider not using an edit session or at least not use an edit operation if you can get away with it.  The option to turn off the undo/redo doesn't always work (Note that the supression of undo/redo logging is not supported for remote database workspaces.)  I would consider using an insert cursor and calling flush every so many records (100? something to experiment with.)  CreateFeature for sure will create an objectId for each call when it is called so, right there sql statements are being generated one at the time... I suggest you look at the following link and avoid creating the features one by one.  There are more direct ways of doing this.  If you need to process the data, you can do that in the fgdb and then load. http://help.arcgis.com/en/sdk/10.0/arcobjects_net/conceptualhelp/index.html#//0001000003rp000000 From the database side, a lot can be done tweak the performance.  The trick is to know what is holding you up.  Do you have versioning?  How big is the user temp space?  What is going on with the roll back log?  Do you have replication?  These are some of the  many things you need to master to get performance out of your database. A good orace DBA can be invaluable in figuring out performance on the Oracle side.  You can also consider using spatial SQL to insert the features directly through the SQL geodatabase API http://resources.arcgis.com/en/help/main/10.1/index.html#//006z00000008000000 I have also dabbled in exporting recordsets into XML and importing them as a new featureclass in Oracle, maybe that can work for you.  Variable size sample sets, some good metrics and some experimentation, I think you will find an efficient way of doing this. ...

In the debugging options, you can try removing the "Require source files to exactly match the original version"  I have found that in some cases vs recognizes the code as different even when it is not. ... View more

I have never user VS2012 but I certainly have encountered this.  Make sure you have don't have some other version of the code kicking around.  In debug, you should be able to open the "modules" window.  This shows all the dlls loaded by ArcMap, including your own and the path to the dll.  Make sure you have the right one. ...

ArcGIS engine is 32 bit only. http://support.esri.com/en/knowledgebase/techarticles/detail/40729 It says 10.1 but the article is referenced in 10.2 documentation also http://resources.arcgis.com/en/help/system-requirements/10.2/index.html#//015100000068000000 ... View more

even if the data link is broken you can still access many properties of the featureclass if you need.  The IDataLayer interface of FeatureLayer has DataSourceName which will be a featureclassName object which has the name and path of the featureclass among other things. ... View more
