How to get back the focus of already opened window in C# Windows forms
I have a windows application. When I click on a button another process starts which pops up the help window. I only want to open 1 window. So if I click on the button I am checking if the process is already started. The problem I am facing is how get the focus of the window that I opened.  
if (processes.Length == 0)
{
      Process.Start();
}
else
{
  // Need to focus on the window already opened. 
}

Cheers
