Given an array S of n integers, are there elements x, y, z in S such that x + y + z = 0? Find all unique triplets in the array which gives the sum of zero.
Note:
- Elements in a triplet (a,b,c) must be in non-descending order. (ie, a ≤ b ≤ c)
- The solution set must not contain duplicate triplets.

This post applies to Visual C# .NET 2002/2003
Suppose you want to run a command line application, open up another Windows program, or even bring up the default web browser or email program... how can you do this from your C# code?
The answer for all of these examples is the same, you can use the classes and methods in System.Diagnostics.Process to accomplish these tasks and more.
Example 1. Running a command line application, without concern for the results:
private void simpleRun_Click(object sender, System.EventArgs e){
System.Diagnostics.Process.Start(@"C:\listfiles.bat");
}
Example 2. Retrieving the results and waiting until the process stops (running the process synchronously):
private void runSyncAndGetResults_Click(object sender, System.EventArgs e){
System.Diagnostics.ProcessStartInfo psi =
new System.Diagnostics.ProcessStartInfo(@"C:\listfiles.bat");
psi.RedirectStandardOutput = true;
psi.WindowStyle = System.Diagnostics.ProcessWindowStyle.Hidden;
psi.UseShellExecute = false;
System.Diagnostics.Process listFiles;
listFiles = System.Diagnostics.Process.Start(psi);
System.IO.StreamReader myOutput = listFiles.StandardOutput;
listFiles.WaitForExit(2000);
if (listFiles.HasExited)
{
string output = myOutput.ReadToEnd();
this.processResults.Text = output;
}
}
Example 3. Displaying a URL using the default browser on the user's machine:
private void launchURL_Click(object sender, System.EventArgs e){
string targetURL = @http://www.duncanmackenzie.net;
System.Diagnostics.Process.Start(targetURL);
}
In my opinion, you are much better off following the third example for URLs, as opposed to executing IE with the URL as an argument. The code shown for Example 3 will launch the user's default browser, which may or may not be IE; you are more likely to provide the user with the experience they want and you will be taking advantage of the browser that is most likely to have up-to-date connection information.
C# code download available from http://www.duncanmackenzie.net/Samples/default.aspx
By the way, this post is a simple port of an earlier VB FAQ post... just in case you thought you had seen it already in your feeds...
