屬性值

Control

主控的 Windows Forms 控制項。The hosted Windows Forms control.

例外狀況

已嘗試指派最上層表單做為裝載的控制項。An attempt was made to assign a top-level form as the hosted control.

範例

下列程式碼範例示範如何使用 Child 屬性將裝載的控制項加入至專案 WindowsFormsHostThe following code example demonstrates how to use the Child property to add the hosted control to the WindowsFormsHost element. 如需詳細資訊,請參閱 逐步解說:在 WPF 中裝載 ActiveX 控制項For more information, see Walkthrough: Hosting an ActiveX Control in WPF.

private void Window_Loaded(object sender, RoutedEventArgs e) 
{
    // Create the interop host control.
    System.Windows.Forms.Integration.WindowsFormsHost host =
        new System.Windows.Forms.Integration.WindowsFormsHost();

    // Create the ActiveX control.
    WmpAxLib.AxWindowsMediaPlayer axWmp = new WmpAxLib.AxWindowsMediaPlayer();

    // Assign the ActiveX control as the host control's child.
    host.Child = axWmp;

    // Add the interop host control to the Grid
    // control's collection of child controls.
    this.grid1.Children.Add(host);

    // Play a .wav file with the ActiveX control.
    axWmp.URL = @"C:\Windows\Media\tada.wav";
}
Private Sub Window_Loaded(ByVal sender As Object, ByVal e As RoutedEventArgs)

    ' Create the interop host control.
    Dim host As New System.Windows.Forms.Integration.WindowsFormsHost()

    ' Create the ActiveX control.
    Dim axWmp As New AxWMPLib.AxWindowsMediaPlayer()

    ' Assign the ActiveX control as the host control's child.
    host.Child = axWmp

    ' Add the interop host control to the Grid
    ' control's collection of child controls.
    Me.grid1.Children.Add(host)

    ' Play a .wav file with the ActiveX control.
    axWmp.URL = "C:\Windows\Media\tada.wav"

End Sub

備註

只能主控一個子控制項,但 Child 可以有任意數目的子系。Only one child control can be hosted, but Child can have any number of children.

子控制項不可以是最上層的表單。The child control cannot be a top-level form.

如果 ChildForm ,則表單的 ControlBox 屬性會設定為 falseIf Child is a Form, the form's ControlBox property is set to false.
