is called, as follows:

        If Command1.Value = False Then
           Command1.SetFocus      ' Set focus to Command1.
           Command1.Value = False ' Set the Value property back to False.
           MsgBox "Command1.Value = " & Command1.Value
        Else
           Command1.SetFocus   'Set focus to Command1.
        End If
     End Sub

1. Create a new Windows CE project in either Visual Basic or eMbedded Visual
  Basic. Form1 is created by default.

2. Add two CommandButtons to Form1.

3. Add the following code to Form1:

        Private Sub Form_Load()
            Command1.Value = False
            MsgBox "Command1.Value = " & Command1.Value
        End Sub

        Private Sub Command2_Click()
            Command1.SetFocus
            MsgBox "Command1.Value = " & Command1.Value
        End Sub

4. Press the F5 key to run the project.

5. Click Command2 and note that a message box appears that indicates that the
  Value property of Command1 has been set to True.
