Examples

The following code example overrides the constructor and the SetAboutBoxDelegate and AttachInterfaces methods of an AxHost-derived class that wraps the Microsoft Masked Edit ActiveX Control. This code requires that you've generated the source code by running the AxImp.exe tool on the MSMask32.ocx file with the /source switch. This code is only shown in C# syntax because that's the only language output by the AxImp.exe tool.

public AxMaskEdBox()
    :
  base("c932ba85-4374-101b-a56c-00aa003668dc") // The ActiveX control's class identifier.
{
    // Make the AboutBox method the about box delegate.
    this.SetAboutBoxDelegate(new AboutBoxDelegate(AboutBox));
}

public virtual void AboutBox()
{
    // If the instance of the ActiveX control is null when the AboutBox method
    // is called, raise an InvalidActiveXStateException exception.
    if ((this.ocx == null))
    {
        throw new System.Windows.Forms.AxHost.InvalidActiveXStateException(
          "AboutBox", System.Windows.Forms.AxHost.ActiveXInvokeKind.MethodInvoke);
    }
    // Show the about box if the ActiveX control has one.
    if (this.HasAboutBox)
    {
        this.ocx.AboutBox();
    }
}

protected override void AttachInterfaces()
{
    try
    {
        // Attach the IMSMask interface to the ActiveX control.
        this.ocx = ((MSMask.IMSMask)(this.GetOcx()));
    }
    catch (System.Exception ex)
    {
        System.Console.WriteLine(ex.Message);
    }
}

Remarks

You typically do not use the AxHost class directly. You can use the Aximp.exe (Windows Forms ActiveX Control Importer) to generate the wrappers that extend AxHost.

The ActiveX Control Importer generates a class that is derived from the AxHost class, and compiles it into a library file (DLL) that can be added as a reference to your application. Alternatively, you can use the /source switch with the ActiveX Control Importer and a C# file is generated for your AxHost derived class. You can then make changes to the code and recompile it into a library file.

Note

If the name of a member of the ActiveX control matches a name defined in the .NET Framework, then the ActiveX Control Importer will prefix the member name with "Ctl" when it creates the AxHost derived class. For example, if your ActiveX control has a member named "Layout", it is renamed "CtlLayout" in the AxHost derived class because the Layout event is defined within the .NET Framework.

Most of the common properties of the AxHost class are only valid and used if the underlying ActiveX control exposes those properties. A few examples of the common properties are BackColor, Cursor, Font, and Text.

Note

If you're using Visual Studio as your Windows Forms design environment, you can make an ActiveX control available to your application by adding the ActiveX control to your Toolbox. To accomplish this, right-click the Toolbox, select Customize Toolbox, then browse to the ActiveX control's .ocx file. For more information, see How to: Add ActiveX Controls to Windows Forms.
