Here is the standard pattern that I use for dealing with dialog buttons:

dlg = Dialog( ..... );
If ( dlg["Button"]==-1,
    Throw()
);

I feel completely sure that there's no way to get a column listing without first opening the data table.

And David: I think you've got the best way of detecting the OK button. There's no specific routine to do this. It all comes down to the fact that the dialog returns a list, aht you've got to use generic list processing thingees to examine it.

I don't know of any direct way to open only selected columns via scripting (though it may be possible) but it may be of interest to note that if your file is stored as an Excel file or an Access database or any other kind of file that has an ODBC driver installed, then you could use the Open Database command with SQL to select and load only the desired columns.
