Using Visual Basic in Arc8 Raster Processing Form Example
This is a VERY simplistic introduction to customizing Arc8 with VB (or VBA) partly because I don’t fully understand what’s going on and partly because it seems like it’s going to be a steep learning curve if you’re not used to VB or COM programming.
