Infra red remote controll?

[Ultimasnake]

How can i use my infrared remote controll in my application?

my infra red device is not connected to a com-port but to my Medion Tv-Radio card (a MD2819 TV-card equipted with a phillips 7134 chipset (or so))

You are going to have to get with the manufacturer and get an API for your hardware, or instructions from them on how to integrate with the hardware.

well there seems to be an public api for this or so.. this C code can read button presses (i guess not sure though) but its written in c(++) can somebody convert this to vb? :S
