Assists interoperation between Windows Presentation Foundation (WPF) and Win32 code.
Assembly: PresentationFramework (in PresentationFramework.dll)
Thetype exposes the following members.
|EnsureHandle||Creates the HWND of the window if the HWND has not been created yet.|
|Equals(Object)||Determines whether the specified Object is equal to the current Object. (Inherited from Object.)|
|Finalize||Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)|
|GetHashCode||Serves as a hash function for a particular type. (Inherited from Object.)|
|GetType||Gets the Type of the current instance. (Inherited from Object.)|
|MemberwiseClone||Creates a shallow copy of the current Object. (Inherited from Object.)|
|ToString||Returns a string that represents the current object. (Inherited from Object.)|
Members of this class allows the caller to have internal access to the Win32 HWND and the parent HWND of a WPF Window. The proper security checks are performed by those members.
Use this class whenever you need a more specific object based on its HWND.
An example scenario is if you need to host a WPF dialog box in a Win32 application. Initialize the with a WPF window object for the dialog box. You can then get the WPF window's handle (HWND) from the Handle property and specify the owner for the WPF window with the Owner property. The following code example shows how to use when hosting a WPF dialog box in a Win32 application.
Another scenario supported by this class is to obtain a HwndSource object from a WPF Window object. The HwndSource enables direct processing of Win32 messages through the AddHook method. By using HwndSource and AddHook in place of a Window you can still handle messages that have no equivalent or handling in WPF. Create a with the Window source, then call Handle on the to get from HWND to HwndSource.
