Delphi7: Get attached monitor properties

由 旧巷老猫 提交于 2019-12-10 16:37:51
问题 How do I get my monitor's properties? I'm mostly interested in the manufacturer name and model type. I also don't want to get it from the registry. (Some PC's like my work PC has restricted access to the property key so I'd rather want to scan a system bus or something other than the reg.) Any ideas? Thanks SoulBlade 回答1: try using the Win32_DesktopMonitor WMI Class. this class have all the information wich you are looking. check this sample code. program GetWMI_MonitorInfo; {$APPTYPE CONSOLE

问题 I want to get the display dimensions of my monitor. Is it possible to do with JavaScript or Flash? I tried the following function: var dpi_x = document.getElementById('testdiv').offsetWidth; var dpi_y = document.getElementById('testdiv').offsetHeight; var width_in = screen.width / dpi_x; var height_in = screen.height / dpi_y; var diagonal_in = Math.round(10 * Math.sqrt(width_in * width_in + height_in * height_in)) / 10; but it doesn't show the fixed diagonal value... because when I change the

问题 I would like to use a monitor which is actually marked "disconnected" in the windows control panel under "Change display settings". (I do NOT mean a physically disconnected monitor.) I know how to add a second monitor in Windows and make it part of desktop. I also know how to make my application run on a primary or on secondary monitor when they are part of desktop. I have a piece of equipment attached to the PC which has a touch screen on it. The touchscreen is connected to the PC over USB

问题 Have a look at this API documentation page... Can anyone explain to me the difference between the rcMonitor and rcWork components of the MONITORINFO structure? Although I'm happy with the idea that a window has areas you can't work with (like the caption for instance), I don't really see how this applies to monitors... All contributions gratefully received... Martin 回答1: rcMonitor is the total resolution of the display rcWork is the max area you can use,eg if you went fullscreen maximized a

Detecting if the monitor is powered off

问题 I have a kiosk type application and I need to be notified if the LCD TV is powered off so I can chastise someone. I'm running Ubuntu 10.10 with nVidia video cards and the nVidia drivers. The TVs are plugged in via HDMI. I've taken a look at nvidia-settings -q ConnectedDisplays and nvidia-settings -q EnabledDisplays , but both always report the monitor is connected. I'm guessing that this value is only set once when the monitor is first powered on? I've also looked at xrandr --properties and

问题 Is there a way to discover what thread currently owns a lock? Specifically I am looking for some code to print out the thread that is preventing a lock from being taken. I want to try to lock for a given timeout, then report which thread is blocking the lock from being taken. 回答1: No. Just write the code: private int lockOwner; private object lockObject = new object(); ... void foo() { lock(lockObject) { lockOwner = Thread.CurrentThread.ManagedThreadId; // etc.. } } There an otherwise
