it turns out you need the ptr. to GetParent() because the "CFileDialog is actually a child of the real dialog"

1. You need to do whatever you need to do with the lat/longitudes stored
2. You would use the ReadFile() function (documentation here).

data = (char **)realloc (data, (datacount +1)*size of (char*));
