In this exercise, let's delete the selected record in the E3Browser. To remove a table's record, use the Delete command.

1.Insert on the Screen a Query object and name it as "DeleteQuery".

2.On the SQL tab, edit the command to the next code.

DELETE FROM ConfigDevice
  WHERE Device = '<%Device%>'

3.In the Remove button, insert the next script.

'Device name
plc = Screen.Item("spDevice").Value
'User confirmation
If MsgBox("Are you sure you want to remove the device '" & _
  plc & "'?", vbYesNo + vbQuestion) = vbYes Then
  Set delQuery = Screen.Item("DeleteQuery")
  delQuery.SetVariableValue "Device", Screen.Item("spDevice").Value
  delQuery.Execute()
End If

4.Execute the application and test this new functionality.
