Sending commands to another app

[JumpyNET]

I need to launch another app and command it to start a certain function. The function can be started by pressing F4. I have accomplished that with the code below. But I'd like to replace the EmulateKeyPress() with something that works better.

 

Private Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)

#Region "Emulate KeyPress"
   Const KEYEVENTF_EXTENDEDKEY = &H1
   Const KEYEVENTF_KEYUP = &H2
   Private Declare Sub keybd_event Lib "user32.dll" (ByVal bVk As Byte, ByVal bScan As Byte, ByVal dwFlags As Long, ByVal dwExtraInfo As Long)
   Private Function EmulateKeyPress(ByVal KeyCode As System.Windows.Forms.Keys)
       keybd_event(KeyCode, 0, 0, 0)  ' Press
       keybd_event(KeyCode, 0, KEYEVENTF_KEYUP, 0)  ' Release
   End Function
#End Region

Private Sub Button_ProcessFiles_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button_ProcessFiles.Click
       Process.Start("TheOtherApp.exe")
       Sleep(500)
       EmulateKeyPress(Keys.F4)
End Sub
