I got the multi-file names from box and loaded into the box.
But it doesn't seem that your code will work for me. Yes, trying to morph it to fit my scenario.
My "DataFileBox" is defined as a ListBox. ListBox does not have a ListCount. It seems you are referring to the Item() which is an ObjectCollection, which has a Count(). But then you check to see if the same indexed value is turned on in the Selected list. But the Selected list is a subset of the real list, and the indexes into to that should be the actual index into THAT list, not the matching index in the total list.
Am I using the wrong collection to start off with?
