Enable visual styles in WPF application

EUREKA!

Steps:
1) I made a Windows form (HostWPF namespace, Form1 is the form).
2) I added a reference => System.Windows.Forms.Integration which contains classes that enable interoperation between the Windows Forms and WPF technologies. When you use System.Windows.Forms.Integration classes, you can host Windows Forms controls on WPF pages, and WPF elements in Windows Forms-based applications.
3) Then added a control (damn Vi$ual $tudio 2010 does not allow to add a WPF window) but after adding I edited the XMAL code in the way I want *Wink
4) The next steps are simple. Download the first attachment. But => see the photo.
It crashes!!!!!
5) Finally???
We must use System.Windows.Forms.Application.Exit(); command because the WPF window behaves like a classical Windows Form.
Download the second attachment. Note that the Windows form's name is Initial.
Enjoy!

 

Terminate WPF/Windows forms applications....

WPF has no concept of MDI applications. In fact Microsoft is trying to discourage any one using that form of application. I'm new to WPF and I really like MDI applications. It allows me to move quickly between windows and compare the content of different windows. Furthermore, sometime the content of one window is useful for another so I can copy and paste. I think it's a great user experience for working mode.
To continue, download the attachment!
It includes two folders, they are very simple code.
The point is how you can terminate an application (Windows Form and WPF).

 

Terminate WPF/Windows forms applications....

Application.Shutdown Method (System.Windows)

Application.Current.Shutdown()


WPF is just a displayer of data. If you want to "compare the content" then you should compare the underlying, databound collections. Copying and pasting is also performed via the databound collections.


Edit: Technically the correct method to terminate an application is to end all threads...

In console programs, the thread that runs the console is the main thread. Close the application by making sure nothing is keeping the main thread open (e.g. Console.ReadKey() or close all worker threads).

In WinForms and WPF programs, the thread that runs the main form is the main thread. Call this.Close() from within the form to gracefully terminate the application. If there are worker threads that are busy, make sure to close them before calling this.Close().

All applications gracefully terminate when all their threads are closed. The only scenario where Shutdown(), Exit(), or similar should be called is in the case of major, unrecoverable error.
