In ArcMAp 9.3.2, I am trying to bring in an acreage calculator .dll buttom that I have used on previous versions. The .dll doesn't show up on the list of available custom addons. Is this a registration problem? I'm at a loss of what could be causing the .dll to not be available on the list.
If your dll is registered correctly, make sure your control is part of the "MxCommands" component category
Heres how it goes if i remember correctly: Right click on an empty space where the toolbars are located, select Customize, go to Commands tab and choose Add from file. Then you select your plugin dll.
Hope this helps
