Interrupt an active screensaver programmatically?

问题 REASON: I'm working on an emergency alert application that needs to display information on a desktop. When the client receives an alert, it pops up a window. If a screensaver is active or the monitor is in standby the alert will not be visible. I'm wondering if it's possible to wake the computer up via some sort of programatic mouse move or system call so that the alert would be visible. I think the reason a mouse move or keypress wakes it up is because of a hardware interrupt so it may not

How can I detect if the screen is locked or screensaver is active from the Terminal in OS X 10.6?

问题 Due to the new limitations of Kerberos in OS X 10.6, I'm working on a script that offers similar functionality to what used to be available in 10.5. Essentially it parses the klist output to see if your ticket is expiring and displays how long until it expires. If we hit the 10 minute mark, it calls kinit to do a GUI password prompt to ask for your kerberos password. If the ticket is expired it does the same thing. The script makes sure that kinit is not running before calling it again so we

How to show a preview of screen saver inside WPF window

由 て烟熏妆下的殇ゞ 提交于 2019-12-06 05:01:25
I want to be able to show a preview of a screen saver inside WPF window. (using a container or control or ...) I know that Windows itself passes "/p" argument to the screen saver to get a preview. But how can I show that preview inside my WPF application? Should I get a handle of it and change its parent to my container o control? How? You need to use Windows.Forms interop, because screen savers expect windows handles (HWND) and in WPF, only top-level windows have them. MainWindow.xaml <Window x:Class="So18547663WpfScreenSaverPreview.MainWindow" xmlns="http://schemas.microsoft.com/winfx/2006
