Display device list

[ThunderMusic]

Hi,
I want to have a list of the display devices available on the computer, just
like the Settings tab do in the desktop properties... What I need is the
DeviceID, it's rectangle(left, top, width, height) and if it's active or
not.

Is there a built-in function to get these informations in c# using framework
2.0 or must I still use APIs?

thanks

I think you are looking for "System.Windows.Forms.Screen.AllScreens" which
gives you a list of screens on the computer. You can then look at each of
the screens <Screenon the list for attributes. There is an example in
BOL.

Regard,
John

Hello ThunderMusic,

why not to enumerate manually?

right, but it only displays screens attached to the desktop and I want
inactive ones too, so I can't use this solution... it would have been great
tought if it had everything...

thanks

way too complicated and not even sure i'll retrieve the good information, I
prefer using PInvoke...

Waw... considering PInvoke and and saying System.Management is too
complicated, you have no idea how many Win32 API calls you'll need and how
many unmanaged structures you will have to convert to managed
representation, quite an error prone taks (unless you are just here to ask
for the code).

A simple call to Win32_DesktopMonitor will return all (and precise) info
you like, following is a complete sample which might change your mind

using System;
using System.Management;

public class Program {
public static void Main() {
SelectQuery query = new SelectQuery("SELECT Availability, DeviceID,
ScreenHeight , ScreenWidth FROM Win32_DesktopMonitor");
using(ManagementObjectSearcher searcher = new
ManagementObjectSearcher(query))
{
foreach(ManagementObject mo in searcher.Get())
{
Console.WriteLine("{0}, {1}, {2} - {3}",
mo.Properties["DeviceID"].Value.ToString(),
mo.Properties["Availability"].Value.ToString(), // WMI docs for
possible values 3 is running full power
mo.Properties["ScreenHeight"].Value.ToString(),
mo.Properties["ScreenWidth"].Value.ToString());
}
}
}

Willy.
