Using Spy++, find out if its the parent, grandparent, or greatgrandparent ... that is getting the Enter key press message. Once you know that, write a class that uses IToolControl.hwnd to find the ancestor and subclass it to capture the  message before it has a chance to block it. http://support.microsoft.com/kb/815775 ...

Hey James, thanks for the quick response. Would you see any problems in having an architecture where a Data Access Layer (DAL) that returns a BindingList of Business Objects (BO's) such that: the BO maintains a strong reference to a IObject (passed as constructor arg) each field in IObject.Fields maps to a BO getter/setter that calls IObject.get_Value/set_Value. BO implements IDisposable, and calls ReleaseCOMObject on the contained IRow in Dispose() DAL calls ReleaseCOMObject on ICursor after returning BindingList<BO>. Thanks again, ... View more

Likewise, since you're using a non-recycling cursor, every row retrieved from the cursor is a new object, which means every row should be managed as well. I've never noticed any ill side effects in apps (or extensions) that do not call ReleaseCOMObject on IFeature/IRow references - has anyone else? For example if I have methods that return generic lists of IFeatures  (List<IFeature>) and releases the cursor when its done, do I really need to call ReleaseCOMObject on each feature when they are no longer in use? Can anyone show me code where failing to call ReleaseCOMObject on an IFeature/IRow causes an exception? Thanks! ... View more

does somePathName refer to a file that exists? If not, maybe try ILayer.SaveAs(somePathName) instead. ... View more

You might try calling IGeometry.SnapToSpatialReference before simplifying. Also, intersect can flake out with nonlinear segments, so maybe call IPolyCurve.Densify before Intersect. ... View more

 I think a combination of: ICharactermarkerSymbol Environment.SpecialFolder.Fonts HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Fonts can accomplish this. ... View more

I recall that workstation ARC/INFO made it possible to centrally manage symbology by editing symbolset files.  However, there is no easy way to do this with ArcGIS.  There really needs to be a way to do this. Maybe something like IGeoFeatureLayer2 could be provided that allows ways to configure how all the properties exposed by IGeoFeatureLayer get initialized before the layer is drawn the first time. ...

Where/when are you wiring the OnChangeFeature event? It sounds to me like you may be wiring it multiple times, which would cause your handler to get called multiple times. ... View more

I think "loaded" means IExtension.Startup has been called.  Of course the dll containing the extension will be loaded into memory before that.  If you have a DLL that is expensive to load (e.g. big) then maybe you could have a small light-weight DLL containing the class that implements IExtension, and have it load the large DLL when Startup is called. ...

Try returning the listview via IDockableWindowDef.UserData.  In your custom tool, you should be able to access the listview by casting IDockableWindow.UserData. ... View more

Hi Jim - Thanks for posting these links. Yesterday I see a total of 10 posts to the new ArcObjects forum. This level of activity is way below what it was on the older forums. Just wondering, with fewer people seeking help for problems on the new forums - does ESRI consider this an indication that people are experiencing fewer problems? Kirk ... View more

oops, sorry, I didn't notice you're talking about arcengine. When your main form starts up, set IToolBarControl.CustomProperty to your main form. Expose a getter on your main form that allows access to the form you want your tool to work with. Add a member variable to your tool that references your main form. Cast the hook passed to your tool in OnCreate  to IToolBarControl and set the member variable main form reference to the IToolBarControl.CustomProperty.  In the MouseDown (or whatever) access your form via m_MyMainForm.MyOtherForm.SomeProperty. ...

You might want to have a dockablewindow instead of a form, in which case you'd use IDockableWindowManager.GetDockablewindow, then access the datagrid or whatever via IDockableWindow.UserData. Or, you could have an IExtension maintain a reference to your form and have your tool find the Extension in the OnCreate, and access the form via methods exposed by the extension. ... View more
