Make your second form modal. In the Unload() event, return the selected code (RETURN Thisform.SelectedCode). In the command button Click() event, put this:

DO FORM SelectACode TO lcSelectedCode

IF NOT Empty(lcSelectedCode) && SelectACode should return "" if no selection made
   Thisform.MyTextBox.Value = lcSelectedCode
ENDIF
