I guess if we are not creating online apps or mobile apps we are not really relevant anymore...  There used to be ArcScripts where users contributed tons of developer material http://arcscripts.esri.com/ They merged that in with EDN then resources, then when esri merged that with arcgis online, I guess that got left behind.  You can search for desktop addins (no COM extensions from what I see.) ...

ArcMap keeps some COM objects alive after the edit session that have the locks.  When ArcMap is shutdown, the objects are destroyed which removes the locks.  ESRI's locking and especially failure to release locks has driven me crazy for years.  If you keep a reference to the featureclasses, workspace and any other objects accessed in your code and explicitly call marshal.ReleaseCOmObject (or even a finalRelease) after the layers have been removed, you may be able to release the locks.  Beware if you use the undo function after removing the layer to get it back, you might get unexpected results. ...

This might be in violation of your RDBMS license also if you user a commercial database such as oracle or sql server.  ArcGIS server allows you to expose Geoprocessing services that could publish your arcpy script to a web service...  Seems like a lot of licensing costs and/or liability to do probably something very simple. ...

Looks to me like you are trying to add a path geometry into a polyline feature when you specify the item 0 of the collection...  If you add the geometry collection (polylineclass object) instead of the first element of the collection, do you get the same problem? ... View more

First of all without exception handlers, it will be next to impossible to debug the code.  Any method called by external code (oncreate, onclick, event handlers...) should always have exception handlers.  Should be the first lines of code any programmer writes.  Secondly the array is declared empty and then never populated.  Checking for is nothing will not work because the array being declared is not nothing, it is however of zero length.  So if you attempt to get element length -1, you are passing in -1 as an index which will cause an error.  You need to check if the length of the array.  The exception being raised, if handled, would tell you so, if indeed that is the problem. ...

Maybe FullName property is nothing...  I don't see the code that declares the IName variable, nor does it have the part that got the dataset enumeration.  Are you getting it from the document, the workspace, a featuredataset?  Do you have layers with broken paths, etc. ... View more

I gave this a try on ArcGIS 10 SP5 and it worked ok...  The table was an Oracle table accessed through SDE.  In the original code, I noticed a space between the "DS" and ".FullName", probably just a copy/paste issue...  When converting VBA code from 9.3 mxds to 10, originally, I noticed that many of my references where pooched.  I had to go to tools, references and remove the missing ones, then it worked ok.  It seems VBA stops loading references as soon a it gets to a missing one, so if the one you need is after that in the list, it doesn't work. Dim mxd As IMxDocument Set mxd = ThisDocument Dim map As IMap Set map = mxd.FocusMap Dim tabcoll As ITableCollection Set tabcoll = map Dim tabl As ITable Set tabl = tabcoll.Table(0) Dim DS As IDataset Set DS = tabl Dim TableName As IName Set TableName = DS.FullName Dim dsName As IDatasetName Set dsName = TableName Debug.Print dsName.Name ...

Looks like you are trying to open the workspace twice.  Open from file with the sde connection opens the workspace, there is no need to retrieve the property set to try to open it again, it will just return the same workspace. Running in debug you may be using a different user (run as...) which has access to the network resource where the sde file is located.  You may also have sharing problems with multiple users accessing the same sde file...  You may want to check if the file exists and its' properties through standard .net methods before trying to open it. ...

Buttons can be moved from one toolbar to another very easily, go into customize mode, move the button to another toolbar.  Having the enabled property on the toolbar level wouldn't make sense for that reason.  The property is on the command. ... View more

If your button is a straight Command, you could have multiple instances of it.  So maintaining a reference to the command on an extension would not work.  The extension will always be a unique instance (by definition), so you can keep a reference to the extension on your two controls and use it to pass values back and forth (this is a model I use a lot.)  You can also place a button on your toolcontrol along side of your combobox, that works nicely some times. ...

IGxApplicationEvents_Event won't show up in intellisense, or any where else but it should still compile and work.  Some quirk of outbound interfaces I have been told. ... View more
