1.0.5000.0 2.0.0.0 Method System.IntPtr A hook procedure is a mechanism by which a function can intercept events before they reach an application. When you override the method for a class, the operating system invokes your override of the function to post operating system messages to the window. By default, the hook procedure centers the dialog box on the screen in response to a WM_INITDIALOG message. This method uses to prevent it from being called from untrusted code; only the immediate caller is required to have permission. If your code can be called from partially trusted code, do not pass user input to class methods without validation. For important limitations on using the LinkDemand member, see [<topic://cpcondemandvslinkdemand>]. This property also uses the security attribute; to override this member, the derived class must have the CustomPermission permission.
