Okay - I brought in the project into VS2008 and tried to build it but received 29 errors and many more warnings.
The problem is that VS2008 is on a computer with only ArcGIS 9.3.1. I believe that is why it won't build. But then again, I use VS2008 for other purposes (and not often) and have not even looked at customizing ArcGIS with .net. So, it may be that I just don't know what I am doing!
We cannot load VS2008 onto the PC with ArcGIS 10. Jeff had offered to install ArcGIS 10 on his PC to test it with all of our editing procedures before we started a mass installation city-wide. The first thing he wanted was the zipper tool. He's our guinea pig (I am sure he will appreciate that).
Is there any way to build this project in VS2008 on a PC with ArcGIS 9.3.1 installed or from Jeff's PC with ArcGIS 10 but no Visual Studio? I could have sworn I thought this tool was going to be made a standard out of the box tool.
