how do I start my application automatically at logon, programatically?

Add a new string value to the registry key:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\Curr entVersion\Run

The value name should be your programs description and the value data should be the full path to your executable.

You could also place a shortcut to your app in the start-up folder of the start menu (this can be done through the file system).

you can use Scheduled Task
