How to add program to startup

Do u need to put it in "start" or only make it run at startup ?
puting it in "start" menu is very classic .. and easy too , just you need to get the start menu location , and put a shortcut of your exe file in the startup folder ..
but if you need the better method to make programme run at startup then u have to put a registry key in this location :
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run //(for the whole machine)
or
HKEY_CURRENT_USER\SOFTWARE\Microsoft\Windows\CurrentVersion\Run //(for the current user only)

the key name isn't important but the value must contains the location of the exe file .

Sure you must know the location of your programme or u need that windows guess it every time it strartup ?
the location of your application could be retrived by "app.path" an it's name by "app.exename" : you need both of them ; [ app.path & "\" & app.exename ]
this is the value of the key you will creat in the regesitry in the specified location .
