No because the clicks are sent to the active window. However if you look at using Windows Hooks (Google will find information) it may be possible to do what you want.

How can I open a System.Windows.Forms.Form with its own message pump from a WPF application?

Re: How can I open a System.Windows.Forms.Form with its own message pump from a WPF application?

4-May-20 5:29

I have a "parent" form in WPF and I would like to add a "child" form of type System.Windows.Forms.Form, which should have its own message pump. I tried the following, but it doesn't compile:

new System.Threading.Thread(delegate ()
{
    System.Windows.Forms.Form childFormWithItsOwnMsgPump = new System.Windows.Forms.Form();
    System.Windows.Application.Run((System.Windows.Window)childFormWithItsOwnMsgPump);
}).Start();

Does anybody know how to solve it?

What exactly are you trying to do? The question does not make a lot of sense.

The parent WPF Window is the main applicaition. The WinForm child form is a high-tech communications bus traffic monitor. Both are big and too much work to re-write in the other way.

Sorry but that does not really tell us anything.

When a communications packet is transmitted/received in the parent application, it queues it to the child application and then the child application decodes it and formats it into a user friendly format and displays it.

First you referred to them as main window and child window.

Now you refer to the child as a child application.

There's a difference. Which is it?

Main application = main window = parent = WPF
Child applicaion = child window = child form = child = WinForm

Re: How can I open a System.Windows.Forms.Form with its own message pump from a WPF application?

4-May-20 10:20

Okay. Why can't you just do the following:

ChildForm F = new ChildForm();
F.Show();

I tried it and I could see the form flashing for a fraction of a second and then it was gone.

Do I have to go in and make changes in the code that looks like some kind of XML or is there a way to accomplish this in the .cs-file alone?

Richard Andrew x644-May-20 11:48

Re: How can I open a System.Windows.Forms.Form with its own message pump from a WPF application?

There is no way to run a Windows Forms form inside a WPF application.

That would be like the USS Enterprise from Star Trek suddenly appearing next to the Millennium Falcon from Star Wars. It would break the space-time continuum.

Re: How can I open a System.Windows.Forms.Form with its own message pump from a WPF application?

4-May-20 21:12

Is it possible to make them "siblings" instead of parent-child? As long the WPS-application can call delegates inside the WinForm-application it should still be useful to me.

Or could I perhaps start a new WPF-windows ( System.Windows.Application.Run(System.Windows.Window) ) that in turn contains the WinForm form (basically, make a WPF window wrap around the WinForm form)?

I just tried the following, but I got a runtime exception (System.InvalidOperationException: 'Cannot create more than one System.Windows.Application instance in the same AppDomain.')

System.Threading.Thread myThread = new System.Threading.Thread(delegate ()
{
    System.Windows.Forms.Form childFormWithItsOwnMsgPump = new System.Windows.Forms.Form();
    childFormWithItsOwnMsgPump.TopLevel = false;
    System.Windows.Forms.Integration.WindowsFormsHost host =
        new System.Windows.Forms.Integration.WindowsFormsHost();
    host.Child = childFormWithItsOwnMsgPump;
    System.Windows.Window WPFwindow = new System.Windows.Window();
    System.Windows.Application app = new System.Windows.Application();
    app.Run(WPFwindow);
});
myThread.SetApartmentState(System.Threading.ApartmentState.STA);
myThread.Start();

Suggestions are still welcome and very much appreciated.

The message is clearly telling you that what you are trying to do is not allowed. You should use a communications link between the two applications to pass the information between them: see WinForms communicate between forms (C#) - TechNet Articles - United States (English) - TechNet Wiki[^]

Richard Andrew x645-May-20 13:31

Re: How can I open a System.Windows.Forms.Form with its own message pump from a WPF application?

5-May-20 13:31

Afraid not. What you're trying to do is not possible.

WPF cannot host a WinForms window, nor vice versa.
