using System;
using System.Collections;
public class LaunchExe
{
public static void Main()
{
string strCmdLine;
strCmdLine ="/C notepad.exe myfile.txt";
System.Diagnostics.Process.Start("CMD.exe",strCmdLine);
}
}
The "/C" tells the program to launch the program and then terminate. Any arguments can be added one space after the executable name. In this case notepad will open and look for myfile.txt.

Yes. You can run (launch) any number of programs residing in the same directory as in which your C# program resides or anywhere else! (as long as you have the privilege to run).
You can pass parameters to external programs, too. But will your other program recognize those parameters? If yes, then you are in luck.
Here is a sample code that you can use to launch your external program.
System.Diagnostics.Process objProcess = System.Diagnostics.Process.Start(@"C:\otherprogram.exe", strParameters);
while (objProcess.HasExited == false)
System.Threading.Thread.Sleep(1000);
retVal = objProcess.ExitCode;
if (retVal == 0)
// You have executed the command okay
else
// the program returned with a code found in retVal.
objProcess = null;
Hope this answered your question.

It has thanks to both of you!
also is it possible to make the window that the application running on minimized when it runs?
Thanks!

Instead of passing the filename and arguments, try passing a ProcessStartInfo object.
System.Diagnostics.ProcessStartInfo objPSI = new System.Diagnostics.ProcessStartInfo();
objPSI.Arguments = "arg1 arg2 arg3 etc.,";
objPSI.FileName = @"C:\YourProgram.exe";
objPSI.WindowStyle = System.Diagnostics.ProcessWindowStyle.Minimized; // or Hidden, Maximized or Normal
pass this object to the Process like so,
System.Diagnostics.Process objProcess = System.Diagnostics.Process.Start(objPSI);
while (objProcess.HasExited == false)
System.Threading.Thread.Sleep(1000);
int retVal = objProcess.ExitCode;
..........

Once again thanks!
