vérifierons ce code: De 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("="); 
}
