. Net support for multiple monitors

Posted on impermanence reading (1733) Comments (0) EDIT favorites category: dot net Nowadays, many video cards are equipped with S terminals and can be directly connected to TVs or projectors (of course, dual-head graphics cards or dual graphics cards can also be used ).
WINXP has built-in support for dual-display. After a dual-output video card is installed, two monitor icons are displayed in the display properties.
Select "extend window desktop to this monitor" on the second monitor to use the second monitor as an extension of the first monitor.
For example, if the resolution of the two monitors is 1280*1024, the two monitors will have a desktop of 2560*1024.
It is easy to use, as long as you drag the window to another monitor.
In this way, you can enable vs2005 on one monitor and enable msdn on another monitor, or write on one monitor.ProgramAnother monitor uses PPLIVE to watch the World Cup.

. Net2.0 in system. windows. forms. the screen class provides support for multiple monitors (see ms-help: // Ms. msdnqtr. v80.chs/MS. msdn. v80/MS. netdevfx. v20.chs/cpref17/html/t_system_windows_forms_screen.htm ).

With this class, it is easy to control the use of dual-monitor in the program. You only need to move the form to the coordinate range of the corresponding monitor.
For example, I use two 17-inch LCD, the resolution of the main monitor is 1280*1024, and the secondary monitor is placed on the right, the resolution is reduced by 1024*768 because the distance is too long.

To move the form to the secondary display, you only need one line of code:This. Publish toplocation=Screen. allscreens [1]. Bounds. location;

To enable full screen display on the secondary monitor:This. Formborderstyle=Formborderstyle. None;
This. Topics topbounds=Screen. allscreens [1]. Bounds;

In the system developed by the author, there is a subsystem that needs to perform operations on the main monitor after entering the system and play video in full screen on the secondary monitor.
The original solution was to use a commercial software, which could implement two sets of mouse and keyboard in WINXP. After two users log on, they work on two monitors separately without interfering with each other. After each restart, I used another user to log on to play the video. Later I thought it was too troublesome. I wrote a simple player after finding the information. After the system starts, the video is automatically played in full screen on the secondary monitor. Saving the trouble of logging on to two users at a time.
