ShowWindow method parameter collation in the User32.dll in the Win32 API

When using the ShowWindow method to set the state of the form, because you do not know the parameter value, it is very easy to use confusion, so the following parameters of the enumeration values, convenient for later use.

Call the ShowWindow method in WPF:

User32api.showwindow (new System.Windows.Interop.WindowInteropHelper (this). Handle.toint32 (), user32api.sw_hide)

The "This" here refers to the current window.
