 `wParam` is the event ID. For different events, `lParam` has different meanings. Currently, two events are supported:
-   * 0: Scaling has ended. `lParam` is not used.

 ### Notes
 
-If your process has a higher integrity level than Magpie, you won't receive messages broadcasted by Magpie due to User Interface Privilege Isolation (UIPI). In such cases, call ChangeWindowMessageFilter to allow receiving the MagpieScalingChanged message.

 ## How to Obtain Scaling Information
 
 Scaling information is stored in the [window properties](https://learn.microsoft.com/en-us/windows/win32/winmsg/about-window-properties) of the scaling window. Currently available properties include:
+
 * `Magpie.SrcHWND`: Handle of the source window
 * `Magpie.SrcLeft`、`Magpie.SrcTop`、`Magpie.SrcRight`、`Magpie.SrcBottom`: Source region of scaling
 * `Magpie.DestLeft`、`Magpie.DestTop`、`Magpie.DestRight`、`Magpie.DestBottom`: Destination region of scaling

 Magpie stops scaling when the foreground window changes, with some system windows being exceptions. By setting the `Magpie.ToolWindow` property, you can include your window and all its owned windows in the exceptions list.
 
 ```c++
-SetProp(hWnd, L"Magpie.ToolWindow", (HANDLE)TRUE);
+SetProp(hYourWindow, L"Magpie.ToolWindow", (HANDLE)TRUE);
