Problem executing a command line command from C# - Need to press Ctrl+C

Yes JF2015. That helped to display data directly to console. Now I got to return the funtion when I read "Initialization Completed". In the delegate(), I might write :
<pre>
string d = e.Data;
Console.WriteLine("LINE = " + d);
if (d != null && d.IndexOf("Initialization Sequence Completed") > 0)
{
connected = true;
Console.WriteLine("********* Connected = " + connected);
}

AND IN ExecuteCommand CODE :
process = Process.Start(ProcessInfo);
process.BeginOutputReadLine();
process.OutputDataReceived += new DataReceivedEventHandler(Process_OutputDataReceived);

if (connected)
return 1;

</pre>
iN MY OUTPUT I GET :
LINE = Tue Feb 01 17:01:27 2011 Initialization Sequence Completed
********* Connected = True

But the if(connected) is not executed to return. I want to keep the process live and return. How to return from ExecuteCommand.

I guess i got to create a seperate class for this where Process is a member and can keep it ailve and kill when am done.

What do you say ?
How to return form the delegate() ?

Thanks

Tried to implement in a new class :
<pre>
public class OpenConnect
{
private Process process;
private ProcessStartInfo processInfo;
private bool connected;
private string command;
private int timeOut, ExitCode = -1;
private StringBuilder sb;

public OpenConnect(string Command, int timeOut)
{
this.command = Command;
this.timeOut = timeOut;
init();
}

private void init()
{
processInfo = new ProcessStartInfo("cmd.exe", "/C " + command);
sb = new StringBuilder();
processInfo.UseShellExecute = false;
processInfo.RedirectStandardOutput = true;
processInfo.CreateNoWindow = false;
}

public int ConnectToServer()
{
try
{
process = Process.Start(processInfo);
process.BeginOutputReadLine();
process.OutputDataReceived += new DataReceivedEventHandler(Process_OutputDataReceived);

if (connected)
return 1;
/*

// Get the results
string result = process.StandardOutput.ReadToEnd();


Console.WriteLine("Process Result = " + result);
//Process.WaitForExit(30000);

ExitCode = process.ExitCode;
Console.WriteLine("%%%%%%%%%%% EXIT CODE = " + ExitCode);
process.Close();*/
}
catch (Exception e)
{
Console.WriteLine("Error Processing ConnectToServer : " + e.Message);
}
finally
{
//Process = null;
//ProcessInfo = null;
}
return ExitCode;
}

private void Process_OutputDataReceived(object sender, DataReceivedEventArgs e)
{
string d = e.Data;
Console.WriteLine("LINE = " + d);
if (d != null && d.IndexOf("Initialization Sequence Completed") > 0)
{
connected = true;
Console.WriteLine("********* Connected = " + connected);
}
}

public void DisconnectServer()
{
processInfo = null;
if (process != null)
{
process.Close();

}
}


}
}

</pre>

How to check the state of connected over here ?
If I return from this class, I believe the process will be working on background and I will be able to call Disconnect and it will perform as expected. Please correct me If i got to improve something here.
And for the state of connected ?

Thanks

I am not getting your point. Can you show a code or sample on other url. According to you, it should be something like this :
<pre>
process.OutputDataReceived += new DataReceivedEventHandler(Process_OutputDataReceived);
while(connected) {
}
</pre>

I feel am wrong somewhere but don't get where. With this the process will also be live and the stringBuffer will also be filled continously, right !

I will Accept your ans and also vote 5, but once my point is suceeded. Have faith.


Thanks

How do you get the timepassed ? I lloked at Thread, Timer(s), DateTime but couldn't find anything that can tell me how much time has passed. Well in DateTime can get the milisecond but of the current time and not timer wise.
For implementation I came to :
<pre>
Thread conThread = new Thread(new ThreadStart(StartConnect));
conThread.Start();

private void StartConnect()
{
int timeout = 30000, timepassed = 0;

OpenConnect oc = new OpenConnect(cmd, timeout);
int retVal = oc.ConnectToServer();
while (!oc.Connected)
{
if (timepassed > timeout)
throw new Exception("NotConnectedException");
Thread.Sleep(100);
}

if (retVal == 1)
Console.WriteLine("YES CONNECTED AND RETURNED");
}
</pre>

This would be more safe , if I am not wrong.
Please guide me.

Thanks a lot. I guess last query reg the topic :
Am not ablt to stop the thread. Thread still seems to be alive/active. My code:
<pre>
try
{
conThread = new Thread(new ThreadStart(StartConnect));
conThread.Start();
//conThread.Abort(); // SEEMS NOT TO EXECUTE
}
catch (ThreadAbortException te)
{
Console.WriteLine("Abort Exception CAUGHT");
}
catch (Exception ex)
{
if (ex.Message.Equals("NotConnectedException"))
MessageBox.Show("Unable to connect to the Server", "Time Out", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
else
MessageBox.Show("Error connecting to the Server : " + ex.Message, "Failed to Connect", MessageBoxButtons.OK, MessageBoxIcon.Exclamation);
}
finally
{
conThread.Abort(); // SEEMS NOT TO EXECUTE
Console.WriteLine("Thread ISAlive = " + conThread.IsAlive); // Shows TRUE
}
MessageBox.Show("***************** Connected To VPN Server - " + connectedTosERVER); // DISPLAYS

Console.WriteLine("Execution Completed "); // DISPLAYS
</pre>

aFTER starting the thread and once the StartConnect()is executed, i should stop/suspend the thread in any way. Calling Abort() after start() or in finally block seeems to have no response. And IsAlive still shows true only. I want ot stop the thread and I belive isalive should show false as the thread is no more active. The MessageBox and "Execution Completed" is also shown. But what about stopping - i mean closing the thread from scratch as the same thread wont be used anywhere in the app except again in the same method.

I looked alot on various sites and tutorials, but couldn't find the solution. Thread.Suspend does, but it is deprecated so don't want to use that one.

What can be the best solution or am I misunderstanding anything here ?

Thanks a lot.
