If notepad is already started, you should write:
If you want to start
The only situation in which the code may not work is when
// import the function in your class
[DllImport ("User32.dll")]
static extern int SetForegroundWindow(IntPtr point);
//...
Process p = Process.GetProcessesByName("notepad").FirstOrDefault();
if( p != null)
{
IntPtr h = p.MainWindowHandle;
SetForegroundWindow(h);
SendKeys.SendWait("k");
}GetProcessesByNamereturns an array of processes, so you should get the first one (or find the one you want).
If you want to start
notepadand send the key, you should write:
Process p = Process.Start("notepad.exe");
p.WaitForInputIdle();
IntPtr h = p.MainWindowHandle;
SetForegroundWindow(h);
SendKeys.SendWait("k");The only situation in which the code may not work is when
notepadis started as Administrator and your application is not.
