How do I open a HTML page from a windows program?

[cheryl]

i mean i need to include a user guide in my program..i know there is a helpProvider which allows user to press F1 to open this help.htm file..but can i use a menu click or toolbar button event click instead of pressing F1?

If you just want to launch a web browser window and display an htm file in it, you can use the System.Diagnostics.Process class.

private void button1_Click(object sender, System.EventArgs e)
{

	System.Diagnostics.Process proc = new System.Diagnostics.Process();
 	
	proc.StartInfo.FileName = @"iexplore.exe"; 
	proc.StartInfo.Arguments = @"C:\ColorPicker.htm";
	proc.Start(); 
}
