I'm looking for any resources on hosting a WPF form within an existing MFC application. Can anyone point me in the right direction on how to do this?
From what I understand (haven't tried myself), it's almost as simple as just giving the WPF control the parent's handle. Here's a Walkthrough: Hosting WPF Content in Win32.

I have a GLFW3 OpenGL project written in C++. I was looking to create a modern GUI to go with it. I have limited experience with XAML and windows WPF but it is intuitive to work with so I really want this to work.
I found 'WpfUnmanagedOpenGL' template from Github https://github.com/kopaka1822/WpfUnmanagedOpenGL and it runs great with a C++ DLL communicating with the Csharp OpenGL host window that is already working within the form using GLAD, not GLFW.
I managed to create a GLFW window with my existing code and it displays as a second popup window when the WPF form is compiled and run. See:
How can I embed this correctly?
I found this question on StackOverflow: embed window(glfwCreateWindow) as child to C++ MFC parent form .
Essentially it says I can set the GLFW window to be a child window of the WPF form. However I cannot get the WPF parent window handle to set it all up.
PLEASE help.
Thanks,
You may want to try to do the opposite. Rather than embedding your Win32 app inside your WPF form, embed your WPF form within your Win32 app instead.

A really neat tutorial:

This is for the legacy .NET Framework though. I have no clue if the same technique can be applied in the new .NET Core framework though.
I host a WPF application in my winforms application via the ElementHost control. I've implemented a logic which listens to unhandled exceptions on WPF side. If an exception is catched, the ElementHost control should be disposed and all related WPF windows should be closed.
This works quite fine, if there is only one WPF window. Since that WPF application can open up more sub windows (which are undocked windows) those windows are not closed when I dispose the ElementHost control.
Is there an easy way to close that WPF window and all child windows from winforms side?
I have tried Application.OpenForms but the sub WPF windows do not show up (makes sense somehow ;-)).
One remark: I do own the WPF code so I could implement something on the WPF side, but I really would like to stick on the win forms side.
Also I would like to consider situations where the WPF window code might be "stuck" and is not able to react and close it self. That's why I'd like to kill the windows from "outside"
So I made up my mind and followed cdkMoose recommendation to let this be handled by the WPF part. It's probably a good idea to let the clean up be done by the one who has the knowledge about what has to be done. Thanks though!
I am looking at the possibility to host a WPF control inside a Winforms application. The reason for this is some animations inside the WinForms application. WPF should be able to support this way better because it (mostly) uses the graphic card to render instead of the CPU.
Now my question:
Are there any cons of hosting a WPF Control inside a Winforms application? Does the WPF Control still use the graphic card for the rendering or does it loose some of its advantages?
Thanks for your help. If you have any inputs or tips feel free to tell me.
EDIT
I found a similar question (but maybe that one is a bit more general, I focus more on the rendering):
Any disadvantage to using an ElementHost to host a WPF UserControl in a Winform application?
Mainly it behaves very like in a normal WPF Application.
But sometimes there are little unexpected behaviors. And it should use the hardware rendering if it would be using in normal wpf applications (depending on your configuration)
Sometimes i had problems with correctly recevien some keyboard keys in events. but there are a lot of artikels descriping the problems and solutions.
For example with some controls you could have problems catching keys. So you should have a look at System.Windows.Forms.Integration.ElementHost.EnableModelessKeyboardInterop

I am new in wpf application..
I am working on window application.it has many module.its one of module is in wpf which is seperate from project.so I want to integrate wpf application into window application project.
Your question is unclear. However, if you are trying to host a WPF object inside of a WinForms application, then yes, that is possible.
A good tutorial can be found here.
Assuming you mean MDI Winform for "windows Application". Here are the steps:
Create a new child Winform.
Add "WPF Interoperability" Element
Add your WPF pages to the WPF interop element
These steps only work in .NET Framework 3.0 or above, where WPF is supported.
You need to add an interop layer between the MDI application and the WPF component that you want to host. This is non-trivial.
1) Determine where the border between your managed and native code will lie. Ensure that you clearly define, delineate, and respect this border, or you will weep tears of pain. This will require use of C++/CLI in any real-world scenario.
I suggest creating a C++/CLI ref class called something like "Launcher" to act as a springboard. It exposes a native API that your native application can consume. The native application provides a pointer to your MDI window and any other req'd information.
2) Use the MDI child pointer and an HwndSource on the WPF component to drop your WPF into the native window.
3) Supply appropriate manual forwarding of window messages from MDI-land to WPF-land via a MessageHook in the HwndSource. Note that you'll manually be handling everything from WM_WINDOWPOSCHANGED to ID_HELP.
Good luck!
You can use ElementHost to add your wpf controls to windows forms. Add ElementHost control to windows form and set your wpf control as ElementHost Child property.
You can find more details here

I am developing WPF windows application using VS 2008 and .NET 3.5. I am trying to use Mozilla Web browser activeX control in my application. I have added it to my tool box. The control is visible in tool box but it is disabled state. I am not able to use it during design time. This does not happen with normal Windows Form Application, I am able to use same control during design time.
Can anybody help me to understand this strange behavior?
Thanks,
Omkar
WPF doesn't directly support ActiveX controls. You'll need Winforms to give it a hospitable runtime environment and leverage the auto-generated AxHost wrapper. The WindowsFormHost control is available to embed winforms controls in a WPF window. The walkthrough that shows the technique is available here.
