MessageReflect

Returns whether the container reflects window messages back to the control, as a Boolean. Read-only.

Syntax: object.MessageReflect

object

required An object expression that evaluates to an AmbientProperties object.

Some Windows notification messages --- such as WM_COMMAND, WM_NOTIFY, and the WM_CTLCOLOR* family --- are by default delivered to the parent window of the control that produced them. When MessageReflect is True, the container reflects those notifications back to the control's own window procedure as OCM_* messages, so the control can handle them itself; when False, the container handles them and the control will not see them.

Example

This example caches the ambient MessageReflect flag so the control knows whether to handle reflected messages.

Private mMessageReflect As Boolean

Private Sub UserControl_AmbientChanged(PropertyName As String)
    Select Case PropertyName
        Case "MessageReflect"
            mMessageReflect = Ambient.MessageReflect
    End Select
End Sub
