Turning of the monitors
-
Is there a way to make a program that turns of the monitors. In Power Option Properties, you kan set the time from 1 minute to 5 hours, but I would like a program that could turn of my monitors right away, just clicking on an icon - is't for using when i watch films on a projektor, so only monitor 1 an 2 shold be turnd of, not monitor 3 (the projektor).
Usually monitors have a "Power" button... :rolleyes: Yes, even I am blogging now!

Use WMI to call the SetPowerState function on an instance of the CIM_DesktopMonitor class and pass 6 as the new power state. Yes, even I am blogging now!

By reading about the System.Management[^] classes and their examples in the .NET Framework SDK. It's the only way to learn. You can also download the Management Extensions for Visual Studio .NET from the links below, which installs extensions into VS.NET's Server Explorer. You can find the class you want and drag and drop it to your project ot create a typed
ManagementObject(supported properties and methods are reflected on the created type), but all this does is provide a wrapper for callingManagementObject.InvokeMethod,ManagementObject.Get, andManagementObject.Put.- Management (WMI) Extensions for Visual Studio .NET 2002 Server Explorer (RTM)[^]

Wow, I thought there would be something easy as just function.TurnOffMonitor(x) ... :sigh:
Its funny how some think someone else should write their code. Is the monitor power button looking like a more feasible implementation for you? :-) This is easily a case where one can overuse technology. By the time it takes you to figure out how to use the objects in
Managementyou could have just shut off your monitor. -

private void Form1_Load(object sender, System.EventArgs e) { this.Location = new Point(0,0); this.BackColor = Color.Black; this.Size = new Size(1280*2, 1024); }all through it doesn't turn off the monitors (since my monitors are backlighted), but at least it dims the light. Thank you guys X| -

My Blog | My ArticlesBut the factory pattern used in the "new APIs" is from .NET 2.0 Beta. You don't want beta developers, do you? :-D I guess maybe I should just be a park ranger out in Washington now that Redmond has decided us programmers are absolete. :(( :-D

Ok, would this be the way to go?
object [] arg = {6}; ManagementClass mc = new ManagementClass("Win32_DesktopMonitor"); mc.InvokeMethod("SetPowerState", arg);problem is that I get the an exception: An unhandled exception of type 'System.Management.ManagementException' occurred in system.management.dll Additional information: This method is not implemented in any class -

Hmm... changing the line now gives this execption: An unhandled exception of type 'System.Management.ManagementException' occurred in system.management.dll Additional information: Type mismatch I'm not sure if I understood your direction 100%. After having installed the WMI extensions, I opened the Server Explore and browsed to Servers|MyComputerName|Management Clas|Desktop Settings and then I right clicked and chose "Generate Managed Class"

That's not the right class. You have to right-click on "Management Classes" and add a new class: root\CIMv2\Win32_DesktopMonitor. Generate a new class from that. Try
object[] arg = new object[] {(ushort)6, DateTime.Now};. It really shouldn't matter since non-decimal numeric types are implicitly convertible, but it's worth a try. This could present a problem since the method is discovered by the types of parameters, and since just6would actually be anint(System.Int32), that could be the source of the problem.Microsoft MVP, Visual C# My Articles

I can't find any Win32_xxxxx in root\CIMv2\ Here is a screenshot of what is see: www.klokmose.dk/images/screen1.jpg[^] Anyway the (ushort)6 didn't help anything
Since the dialog is showing the friendly names, the logical conclusion would be to find something that resembles "Win32_DesktopMonitor", like "Monitors". Add that and generate a class for your project.
