@MMK I was thinking that as well, but what happens if the user closes the browser and wants to re-launch from the OP's app? — Jay

Why don't you disable the button just after you click on it ? — Jomy John

if (Process.GetProcessesByName("iexplore").Length == 0) System.Diagnostics.Process.Start("IExplore.exe", @"C:\Help.html");

Disable button.
Control clicking by a flag

ie ; on_btn_clkd()
{
if(!previouslyClickd)
{
(Click functionalities)
previouslyClicked = false;
}
else
return ;

Try to use this piece of code:

bool ProcessIsRunning(string process) { return (System.Diagnostics.Process.GetProcessesByName(process).Length != 0); }

Usage:

if (!ProcessIsRunning("IExplore.exe")) System.Diagnostics.Process.Start("IExplore.exe",@"C:\Help.html");

You can do like this

private void Form1_Load(object sender, EventArgs e) { IeProcess = new Process(); startInfo = new ProcessStartInfo("IExplore.exe"); startInfo.WindowStyle = ProcessWindowStyle.Maximized; } private void buttonStackoverflow_Click(object sender, EventArgs e) { startInfo.FileName = "www.Stackoverflow.com"; IeProcess.StartInfo = startInfo; IeProcess.Start(); } private void buttongoogle_Click(object sender, EventArgs e) { startInfo.FileName = "www.google.com"; IeProcess.Start(); }

Make use of ShDocVw.dll..
declare in instance of Internet explorer in your class

InternetExplorer wBrowser;

and in your button click add

if (wBrowser==null) { wBrowser = new InternetExplorer(); wBrowser.Visible = true; wBrowser.Navigate(@"C:\Help.html"); }

you need to add reference to ShDocVw which you will find in System32 in your project and import namespace using SHDocVw;
