Check this code: From MSDN
// Get a handle to an application window.
[DllImport("USER32.DLL", CharSet = CharSet.Unicode)]
public static extern IntPtr FindWindow(string lpClassName,
string lpWindowName);
// Activate an application window.
[DllImport("USER32.DLL")]
public static extern bool SetForegroundWindow(IntPtr hWnd);
// Send a series of key presses to the Calculator application.
private void button1_Click(object sender, EventArgs e)
{
// Get a handle to the Calculator application. The window class
// and window name were obtained using the Spy++ tool.
IntPtr calculatorHandle = FindWindow("SciCalc", "Calculator");
// Verify that Calculator is a running process.
if (calculatorHandle == IntPtr.Zero)
{
MessageBox.Show("Calculator is not running.");
return;
}
// Make Calculator the foreground application and send it
// a set of calculations.
SetForegroundWindow(calculatorHandle);
SendKeys.SendWait("111");
SendKeys.SendWait("*");
SendKeys.SendWait("11");
SendKeys.SendWait("=");
}
