Well got this script to work, but it wasnt using the tips from above... One of error messages related to 'Layer 0', and I noticed that the problem seemed to occur (in this particular isntance) to a shapefile I had half way down in my TOC, so I dragged the shapefile to the top of my TOC, and ran the macro again, and it worked. I have tested this with another project, and it only seems to work when the shapefile is first in the TOC. It's not something we will use everyday, so this solution will do for now! Dan That's because your code is written to operate on the first layer in the TOC. Set pGeoLayer = pMap.Layer(0) ... View more

The way that will always work is to query for all of the features, loop through them and look for the min and max values.  You can also use IDatastatistics.  Depending on the datasource, you could use a standard SQL query to get the min and max.  Keep in mind though that the OIDs may not be sequential.  There could be gaps caused by deleting features and other operations. A feature class could have a feature with OID 1 and another feature with OID 1000 and only have 2 features in it. ... View more

You could call Remove or RemoveAt to remove the item from the list then call Insert to add it back at the desired index position. ... View more

You would need to stop the feedback and get the polyline object it returns.  Restart the feedback, QI over to IPointCollection and add all of the points except for the last one back to it.  After that, call MoveTo and pass in the current mouse location to connect the feedback back to the mouse cursor. ...

The Using statement scopes the resource (the variable you declare) to the block of code between the Using and End Using statements.  The purpose of the Using statement is to limit the scope of a resource within a larger block of code and to guarantee that it is disposed as soon as the End Using statement is executed.  So, is it ok to nest Using statements?  Yes.  It's really no different than nesting loops or If/End If blocks.  In your case, you're using a cursor within a loop.  Each loop iteration opens a new cursor.  That cursor needs to be released with each loop iteration.  Each time a cursor is created, a table in the database is opened.  It will not be closed until the cursor is released, so if you don't release the cursor within each loop iteration it will keep opening tables and not closing them.  Eventually, you'll hit the max. number of open tables and an exception will be thrown.  So, that cursor needs to be managed by its own ComReleaser object declared within the loop.  If you use the ComRelease declared outside of the loop then the cursors created inside the loop will not be released until after the loop is exited. ...

IMO, the best practice is not to use ESRI's ComReleaser class at all.  The best way to manage your COM objects is to do it yourself so that you know what's going on and have full control over it.  When looping through a cursor, you should also be releasing the row/feature objects within the loop before assigning the reference to the next item in the cursor. Dim featureCursor As IFeatureCursor = featureClass.Search(Nothing, False) Dim feature As IFeature = featureCursor.NextFeature Do While feature IsNot Nothing   ' do something with the feature   Marshal.ReleaseComObject(feature)   feature = featureCursor.NextFeature Loop Marshal.ReleaseComObject(featureCursor) ...

Have you tried modifying the geometry used by the text path (ITextPath.Geometry)? ... View more

Sorry, I was thinking the map title was a type of text element but it isn't.  You might try using a standard text element instead of a map title. ... View more

Try positioning the element with a point geometry instead of an envelope.  You can set the horizontal and vertical alignment properties on the element so that it aligns itself on the point the way you want it to. ... View more

I don't know how to explain it other than to repeat what I've already said.  The OpenDocument event fires when a document is opened.  Inside this event, you are calling your form.  You cannot close ArcMap or load another document from this form because ArcMap is already in the process of opening a document.  I have tested this and each time I try it I get an Access Denied error.  If you want to close ArcMap or load another document then you will have to do it from somewhere other than the OpenDocument event. Also, ArcObjects is not a language.  The language you are using is VBA.  It's important to tell others this when asking a question because the vast majority of the people on this forum do not use VBA.  They use a .NET language, C++ or Java.  How you do things can vary greatly depending on your programming environment so telling people what environment you're using will get you a correct answer much faster. ...

No, that is not correct.  First, you should have stated that you're using VBA to begin with so that someone trying to answer your question would know what environment you're working in.  As I said in my last post, VBA has a built-in shortcut named Application.  So the code would be: Application.Shutdown() However, since you're calling your form from ArcMap's OpenDocument event you will not be able to close ArcMap or load another document because ArcMap is already in the process of opening a document.  You can only do these kind of things after the document has been loaded. ...

You always have a way to get a reference to the ArcMap application.  If you're implementing an extension then it's passed into the Startup method.  If you're implementing a command or tool then it's passed into the Create method.  Addins have something similar but I don't work with them so I don't know it off the top of my head.  In VBA, it's a built-in environment shortcut named Application. ...
