I'm investigating if it's possible to host any type of window in WPF by handle. I've been exploring the HwndHost class, although all the examples I've come across is using a Win32 handle. Is it possible to host any window type by handle?
Yes, it is possible. Here is a quick link from MSFT on hosting Win32 controls:
https://msdn.microsoft.com/en-us/library/aa970061.aspx
I've actually worked on a project where we hosted a Java client application (don't ask why) inside a WPF control where we grabbed the Win32 handle from the Java application. Eventing can be tricky, but it can be done.

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.
is it possible to add an instance of a java application as a child form a .NET Form?
Thanks
I don't think it is. A Java program will have to run in its own process. A window from one process cannot be the child of a window of another process.
EDIT: Apparently I was wrong, it is possible to have a window from one process be a child of a window from another process, for example here
It might work with Java, depending on how the Java GUI framework the application uses works with Windows controls. The Windows Spy can help you figure out a little more about your Java application.
There is no easy and straightforward way todo that, at least that I'm aware of. One of possible solutions could be to make from your Java application an Applet and recall it inside embedded in Windows Form WebBrowser control. After you need to care about communication between your application and applet.
Some hints can find here
Hope this helps.
I am developing an application that needs to a host native Win32 window and somehow i have no clues how to do that.
I need to create a WPF dialog window that could display native Win32 control on it. This dialog window will have WPF controls on it as well, so i am looking for some sort of Grid that i could take HWND of and send it to the unmanaged C++ control, so it could draw on it.
Is that possible ?
I don't need to know what happens within that surface, just need to let C++ dll to draw on it and all i need to do is to pass HWND that has proper size (which i know).
I am kinda new to WPF (used to do win32 programming) and quite lost (but i now how to interface it to C# .NET etc)
Would be great if you could send me any hints :)
you can start by following the instructions/steps here: Hosting Win32 Content in WPF
from the article introduction:
A Walkthrough of Win32 Inside Windows Presentation Framework (HwndHost)
To reuse Win32 content inside WPF applications, use HwndHost, which is
a control that makes HWNDs look like WPF content. Like HwndSource,
HwndHost is straightforward to use: derive from HwndHost and implement
BuildWindowCore and DestroyWindowCore methods, then instantiate your
HwndHost derived class and place it inside your WPF application.
If your Win32 logic is already packaged as a control, then your
BuildWindowCore implementation is little more than a call to
CreateWindow.
then if you have a specific issue ask here in SO and people will help you on specific points.
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.

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.
