Is there any event when a new process is created. I'm writing a c# application that checks for certain processes, but I don't want to write an infinite loop to iterate through all known processes continuously. Instead, I rather check each process that is created or iterate through all current processes triggered by an event. Any suggestions?
Process[] pArray;
while (true)
{
pArray = Process.GetProcesses();
foreach (Process p in pArray)
{
foreach (String pName in listOfProcesses) //just a list of process names to search for
{
if (pName.Equals(p.ProcessName, StringComparison.CurrentCultureIgnoreCase))
{
//do some stuff
}
}
}
Thread.Sleep(refreshRate * 1000);
}
WMI gives you a means to listen for process creation (and about a million other things). See my answer here.
void WaitForProcess()
{
ManagementEventWatcher startWatch = new ManagementEventWatcher(
new WqlEventQuery("SELECT * FROM Win32_ProcessStartTrace"));
startWatch.EventArrived
+= new EventArrivedEventHandler(startWatch_EventArrived);
startWatch.Start();
}
static void startWatch_EventArrived(object sender, EventArrivedEventArgs e)
{
Console.WriteLine("Process started: {0}"
, e.NewEvent.Properties["ProcessName"].Value);
if (this is the process I'm interested in)
{
startWatch.Stop();
}
}
