Hosting Out-of-process ActiveX control in WPF

Question

Hi to all!

Can anybody help me?

I have an out-of process third-party ActiveX control. I just need to host it in the WPF Application. What should I do for it? I have not seen any examples of doing this in the internet.

Thanks

P.S. This third-party out-of-process ActiveX Control was created in C++/Qt using ActiveQt

Hi,

 

Here is an useful document with a ready-to-run example of hosting ActiveX controls in your WPF based application, you can follow it step by step.

 

Link: http://msdn.microsoft.com/en-us/library/ms742735.aspx

Some code snippets are shown in the following:

XAML code:

 <Window x:Class="HostingActiveX.Window1"

    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    Title="Hosting the Terminal Services ActiveX Control">

      <DockPanel Name="panel" Margin="10">

        <StackPanel Margin="0,0,0,10" DockPanel.Dock="Top" Orientation="Horizontal">

          <TextBox x:Name="serverBox" Width="200" Margin="0,0,10,0"/>

          <Button x:Name="connectButton" Click="connectButton_Click">Connect</Button>

        </StackPanel>

      </DockPanel>

</Window>

 

In the code behind:

 

using System.Windows;

using System.Windows.Forms.Integration;

using System;

 

namespace HostingActiveX

{

    public partial class Window1 : Window

    {

        AxMSTSCLib.AxMsTscAxNotSafeForScripting termServ;

 

        public Window1()

        {

            InitializeComponent();

 

            // Create the host and the ActiveX control

            WindowsFormsHost host = new WindowsFormsHost();

            termServ = new AxMSTSCLib.AxMsTscAxNotSafeForScripting();

 

            // Add the ActiveX control to the host, and the host to the WPF panel

            host.Child = termServ;

            panel.Children.Add(host);

        }

 

        void connectButton_Click(object sender, RoutedEventArgs e)

        {

            termServ.Server = serverBox.Text;

            termServ.Connect();

        }

    }

}

 

Hope this helps.

Thanks.

This one works but I cannot click on the program opened  in the remote machines. I cannot start new program from the remote desktop session launched through this.
