Are you sure you've added your layer extension to a layer via ILayerExtensions.AddExtension? ... View more

Perhaps use the RecordSet class.  It implements IXmlSerialize, but I've never tried it.  Create a new empty recordset, then use IRecordSetInit.Insert to insert features. ... View more

I would add an arcmap (or editor) extension (IExtension) and have all toolcontrols set a reference to the extension when OnCreate is called. Each toolcontrol would change a property exposed by the extension.  If a toolcontrol needs to know when a property has changed, then it will need to subscribe to an event on the extension, and you'll need to raise an event when the setter of the property is called. ...

Using IDisplayTable for any featurelayer (regardless of whether it was created as a selection layer) should return the rows that you see when you display the layer attribute window in arcmap. ... View more

If you implement ILayerExtensionDraw, the parent layer gets passed as an arg, in either of the two methods. I found it unstable to keep a (strong) reference member varialbe to the parent layer, maybe some sort of weak reference strategy could be used though - I've never tried. ... View more

How are you populating your attribute window? You should cast the featurelayer to an IDisplayTable, then load rows into your datagrid (or whatever) by looping through rows returned by the ICursor returned from IDisplayTable.SearchDisplayTable. ... View more

When I run the code above with a path to the data in the attached file gdb, and open the attribute window, I only see one row. Right clicking on the layer and choosing zoom to extent will zoom to whatever features are present in the layer (created using code posted previously). However, I see that IGeoDataset.Extent for the layer is still the full extent of the layer, so  I guess zoom to layer uses some other method.  I wouldn't think it would loop through each feature to build an envelope, but I don't see what else it would use.  Setting ILayer2.AreaOfInterest doesn't change the behavior of zoom to extent. 9.3.1 sp 1 Vista64 ...

Just implement IExtension like you normally would, but instead of implementing IExtensionConfig - which would make it show up in the Extensions window - write a static method called Enabled.  It would follow the singleton pattern, with a static member variable reference to to m_MyExtension.  If the m_MyExtension == null, Enabled would return false, otherwise it would use another boolean member variable m_Enabled. You'll need to write a command to toggle it for you, since it won't appear in the Extensions window. ... View more

If you don't implement IExtensionConfig, then I don't think it will show up in the Extension Manager window. Any tools/commands etc. that need to see if the extension is toggled on, should first check to see if it is loaded using IJITExtensionManager.IsLoaded, if it is not loaded I guess that means it isn't "on" - otherwise access access an Enabled method.  This could be done as a static method on your extension. ...

Are they exact intersections?  If not you'll need to buffer them into polygons first. Otherwise,  maybe try using a multipoint instead of a geometrybag. You probably should explicitly set the spatialreference of the multipoint to that of the points you are adding to it.  Performance might be improved using ISpatialIndex.Invalidate on the multipoint before assigning it to the spatialfilter. ...
