Auto Seek Question from Xdemo

[GeneB]

In the example from Xdemo, Sample Group 2, "Auto Seek 1":
I would like the item in the browse that is highlighted to appear in the Get when "Enter" is pressed, and have the buttons "Yes/No" then receive focus.

What change/addition, please. Thank you.

Code: Select all

FUNCTION XSample_43

/*
Browse with AUTOSEEK (DataBase)

This sample demonstrates a single @ DCSAY..GET and a Browse.  The
GET is used to enter a string to seek.
*/

LOCAL GetList := {}, cSeek := Space(20), oBrowse

IF !File('..\XDOC\EXPRESS.DBF')
  DC_MsgBox({'Sorry.  The database required to show this feature',;
             'is not included in the demonstration version', ;
             'or the ..\XDOC\EXPRESS.DBF file does not exist'})
  RETURN nil
