The Intersect method returns a point collection when called using the 0-dimension flag.  Your code should check that this point collection is not null as well as check to make sure the point collection contains at least one point. ... View more

The problem is that you're casting from IFeature to IPolyline.  This is an invalid cast.  You need to be getting the Shape of the feature and casting that to IPolyline, not the feature object itself. ... View more

The ideal way to do this would be to install your gis.dll separately and register it in the GAC.  However, this would require that each new version of your dll be installed with policy files to point applications using an older version to the newer version.  This isn't hard to do, it just requires more work.  You can also install the gis.dll file with each extension and put it in the same directory as your extension's assemblies.  If you go this route then you have to make sure that you change the version number on the gis.dll file each and every time you make a change and recompile.  If you don't then your extensions will use whichever file is loaded first.  When the first extension loads, the .NET runtime loads any dependencies that it needs, which will include your gis.dll.  When your other extension loads, the gis.dll that sits alongside the extension assembly will NOT be loaded because it has the same version number as the file previously loaded.  The .NET runtime can't tell that the gis.dll is different from the one already loaded because it is only looking at the version number.  This is why it is important to change the version numbers.  Since you're extensions are not using the correct gis.dll, I'm guessing you didn't increment the version number when you made changes to the dll. ...

Which versions are you talking about?  ESRI's position is that you recompile your application for each version you want to support and my experience is that this is the best way to do it.  Backwards compatibility is not supported, so you can't deploy your application to computers with an earlier version of the software (including service packs) unless you recompile against that version.  You may be able to deploy to computers with a newer version, but again, recompiling is recommended.  You cannot deploy an application compiled against 9.x to a computer with 10.x installed.  You will have to recompile as well as follow ESRI's instructions on how to upgrade your application from 9.x to 10. ...

The first thing I would check is your project's Target Platform setting.  It needs to be set to x86.  By default, it's set to AnyCPU which will cause problems when you try to run your app on a 64-bit system. ... View more

When you call DoModalOpen, the selected item(s) are returned in the IEnumGxObject reference that you pass into the method.  However, since you are using the dialog to browse to a Save location then you should be calling DoModalSave instead of DoModalOpen.  It's been a while since I've used this dialog for saving things but if I remember right, you have to build the full path by combining the FinalLocation property and the Name property.  I could be wrong on that though. ...

It's been a while since I've worked with data graphs but I seem to remember that there are some things that are not exposed through ArcObjects.  One thing you can try is to create the graph in ArcMap with all of the properties set like you want then and save it out as a template, which you can then load when you create the graph through code. ...

You should have changed this line: IActiveView activeView = ArcMap.Document.ActiveView; To this: IActiveView activeView = ArcMap.Document.FocusMap As IActiveView; ... View more

The active view of a document can be either the map or the page layout depending on which view the document is in.  If you want your tool to only work on the map then get your active view reference from the document's focus map reference instead of its active view reference. IActiveView activeView = ArcMap.Document.ActiveView; Change the line above to get the focus map instead of the active view.  When the document is in layout view then your tool will only respond to clicks on the map and will ignore clicks on the layout. ...

Is the XP machine 32 bit and are you using Visual Studio .NET?  If so, then check your target platform setting in Visual Studio to make sure it's set to x86 for all configurations. ... View more

No, ArcObjects are 32-bit so you'll have to set the target platform of your project to x86.  If you do not, then your code will not run as expected. ... View more
