In order to give the focus to the automation created text box, a dialog function is added in Scripter. To do this, the first line of the creation of the dialog will need to be changed slightly and a function should be added after the End Sub line in the script. The first line will need to reference the dialog function:

        Begin Dialog UserDialog 550,112,"Enter Run Date",.DialogFunc

After the End Sub line, add this dialog function:

       Function DialogFunc%(DlgItem$, Action%, SuppValue%)
              DlgFocus "Text1"
       End Function

See attached user dialog example -- text box focus for and example script that uses this dialog box function
