'الاستخدام
Dim instance As Shape
Dim value As Boolean

Property Value

Type: System.Boolean
true if the control can receive focus; otherwise, false. The default is true.

Remarks

In order for a control to receive input focus, the Visible and Enabled properties must both be set to true for the control and all its parent controls.

To prevent an individual control from receiving focus, set its Enabled property to false.

Examples

The following example sets the focus to the specified Shape, if it can receive focus.

Public Sub ShapeSetFocus(ByVal shape As Microsoft.VisualBasic.PowerPacks.Shape)
    ' Set focus to the control, if it can receive focus.
    If shape.CanFocus Then
        shape.Focus()
    End If
End Sub

public void ShapeSetFocus(Microsoft.VisualBasic.PowerPacks.Shape shape)
{
    // Set focus to the control, if it can receive focus.
    if (shape.CanFocus)
    {
        shape.Focus();
    }
}
