VBA Coding for Selected features

AdamOller

I've developed the following form and it has all of the possible field attributes that could be selected to identify one single unique attribute. I want to be able to select all three and choose "calculate" to provide a message box that will give the unique attribute. My coding abilities are limited to the Getting to Know ArcObjects book which has helped me greatly in creating this form and adding all of the items in the drop down menus.

Thanks!

Yes, there are four different species and there is a fourth field that has total number of species that has a particular year, route, and species ID associated with it in the row itself.

Oh, I see, you're not actually calculating the value -- you just need to return it from a single field.

One way to do that would be to use either an IFeatureClass.Search or an IFeatureLayer.Search, and pass in an IQueryFilter with its WhereClause set to the fields and values for your three parameters. From the cursor returned from that, get the value of your fourth field.

Here's the WhereClause reference to get you started.
