Start a Process from a Windows Service

[123qweasdzc]

Hello .

I want to start a process from a Windows Service. To do that I have the following code:

private System.Timers.Timer timer;
private Process process;
private bool isProcessRunning = false;

protected override void OnStart(string[] args)
{
timer = new System.Timers.Timer();
timer.Interval = 5000;
timer.AutoReset = true;
timer.Elapsed += new System.Timers.ElapsedEventHandler(startProcess);
timer.Start();
}

private void startProcess(object sender, System.Timers.ElapsedEventArgs e)
{
if(!isProcessRunning)
{
EventLog.WriteEntry("Process will start...");
isProcessRunning = true;
process = new Process();
process.StartInfo.FileName = @"C:\Program Files\AllMyMovies\allmymovies.exe";
process.Start();
}
}

I cannot understant why the process do not start because the entry "Process will start" is written in the event viewer log. Can someone say what's wrong? I hope so .

Thanks in advance,

Ricardo

Problem solved. The problem is that running a process from a windows service, it will not launch an user interface. All the processes run in backround.

For me there is no problem because the real process I want to start do not have a user interface.

you can check to see if you are able to launch an app with an interface by checking the state of this boolean:

System.Windows.Forms.SystemInformation.UserInteractive

Its saved me aon a few occasions
