Hi,

now you have a MathLink program. You could use it either by:

- starting it as you did. the window pops up, asking you for a name for
your link. My favorite one is "blub". So type in a name and klick ok.

- go in a Mathematia-notebook and call

lnk=Install[LinkConnect["blub"]]

and you get a LinkObject. You can look what  functions are provided by
the link with

LinkPatterns[lnk]

you should now be able to call

AddTwo[1,2]

and to uninstall the link with

Uninstall[lnk]

The other possibility (which you should use when your program is bugfree
and finished) is to Install the link directly with

lnk=Install["full\path\to\link\addtwo.exe"]

Thats it. Please check in the documentation-center the doc for

Install
Uninstall
LinkConnect

Cheers
Patrick
