How can I check if a process with a given name is running?

It seems I have to use GetProcessesByName:

http://msdn.microsoft.com/en-us/library/system.diagnostics.process.getprocessesb
yname(VS.71).aspx

unfortunately, "No example is available for JScript".

What would an example look like if I wanted to check if notepad.exe is
running?

The C# example is going to be the closest. Slap that into JScript.NET and
see what breaks. I suspect you'll only need to tidy up a few syntatical
things and you'll be there.

If you mean JScript in the standard scripty sense then whilst a port may be
possible that make use of the System.Diagnostics.Process object there will
be ugly hoops to jump through.

In this case you'll be better off finding a VBScript example of doing this
with WMI or ADSI then porting to JScript.

Here is one which enumerates all processes in JScript - as found on
Microsoft Platform SDK for Windows Server 2003 R2
(5.2.3790.2075.51.PlatformSDK_Svr2003R2_rtm.img) in Process.Js:

try
{
var e = new Enumerator
(GetObject("winmgmts:").InstancesOf("Win32_process"));

for (;!e.atEnd();e.moveNext())
{
var p = e.item ();
WScript.Echo (p.Name, p.Handle);
}
}
catch (e)
{
WScript.Echo ("Error in script: " + e);
}

And for the reference, here is a sample script I wrote which checks if
any given processes are running:
