public void NetSend(string mname,string strMessage)

{

/* This method is created by Anton Zamov. web site: http://zamov.online.fr Feel free to use and redistribute this method in condition that you keep this message intact. */ this.sysname=mname;

this.strMessage = strMessage;

ThreadStart tStart = new ThreadStart(this.SendMessageThread);

Thread senderThread = new Thread(tStart);

senderThread.Start();

}

public void SendMessageThread()

{

/* This method is created by Anton Zamov. web site: http://zamov.online.fr Feel free to use and redistribute this method in condition that you keep this message intact. */

try

{

string strLine = "net send " + sysname + " " + this.strMessage + " > C:netsend.log";

FileStream fs = new FileStream("c:netsend.bat" , FileMode.Create, FileAccess.Write);

StreamWriter streamWriter = new StreamWriter(fs); streamWriter.BaseStream.Seek(0, SeekOrigin.End); streamWriter.Write(strLine);

streamWriter.Flush();

streamWriter.Close();

fs.Close();

Process p = new Process();

p.StartInfo.FileName = "C:netsend.bat";

p.StartInfo.WindowStyle = ProcessWindowStyle.Hidden;

p.Start();

p.WaitForExit();

p.Close();

FileStream fsOutput = new FileStream("C:netsend.log", FileMode.Open , FileAccess.Read);

StreamReader reader = new StreamReader(fsOutput); reader.BaseStream.Seek(0,SeekOrigin.Begin);

string strOut = reader.ReadLine();

reader.Close();

fsOutput.Close();

}

catch(Exception)
