Use the <a href="http://msdn.microsoft.com/en-us/magazine/cc164123.aspx" rel="nofollow noreferrer">GetSystemMetrics()</a> function in the user32.dll. Use <a href="http://ttp://msdn.microsoft.com/en-us/library/ms724385.aspx" rel="nofollow noreferrer">PInvoke</a> to call it. The following is sample code provided by the first link. The second link tells you how to invoke it in .NET.

<pre><code> BOOL IsRemoteSession(void){
 return GetSystemMetrics( SM_REMOTESESSION );
 }
</code></pre>

Complete code:

<pre><code>[DllImport("User32.dll")]
static extern Boolean IsRemoteSession()
{
 return GetSystemMetrics ( SM_REMOTESESSION);
}
</code></pre>

There's also the <code>SystemInformation.TerminalServerSession</code> Property, which determines whether or not the client is connected to a Terminal Server session. The <a href="http://msdn.microsoft.com/en-us/library/system.windows.forms.systeminformation.terminalserversession(VS.80).aspx" rel="nofollow noreferrer">code provided</a> by MSDN is extensive, so I won't duplicate it here.

Assuming you're at least on .NET Framework 2.0, there's no need to use P/Invoke: just check the value of <code>System.Windows.Forms.SystemInformation.TerminalServerSession</code> (<a href="http://msdn.microsoft.com/en-us/library/system.windows.forms.systeminformation.terminalserversession(VS.80).aspx" rel="noreferrer">MSDN</a>).

In addition to making the initial check to see if your desktop is running in a RDP session, you may also want to handle the situation where the remote session is connected or disconnected while your ap is running. You could have an app running on the console session and then someone could initiate a RDP connection to the console. Unless your application is periodically making the call to GetSystemMetrics, it's going to assume that it's not running as a terminal services session. 

You would have your app register for session update notificiations through WTSRegisterSessionNotification. That will allow your applicaiton to be immediately notified is a remote connection has been opened or closed to the desktop session that your application is running under. See <a href="http://pinvoke.net/default.aspx/wtsapi32.WTSRegisterSessionNotification" rel="nofollow noreferrer" title="pinvoke.net: WTSRegisterSessionNotification (wtsapi32)">here</a> for some sample C# code.

For a some good Delphi Win32 exampale code for using WTSRegisterSessionNotification, see this <a href="http://www.swissdelphicenter.ch/torry/showcode.php?id=1109" rel="nofollow noreferrer">page</a>.

I have a .net winforms app which has a few animation effects, fade ins and scroll animations etc. These work fine however if I'm in a Remote Desktop Protocol session the animations start to grate.

Can someone suggest a way of determining whether or not an app is running across an RDP session so I can turn the effects off in this case?

How do I tell if my application is running in an RDP session

服务器

Windows

我有一个.net winforms应用程序，它有一些动画效果，淡入和滚动动画等。这些工作很好，但如果我在一个远程桌面协议会话，动画开始格栅。有人能建议一种方法来确定应用程序是否正在RDP会话中运行，这样我就可以在这种情况下关闭效果吗？
