Point to Poin WiFi radio singal match. To match LOS VB6 is most preferred

I need a basic software written in VISUAL BASIC 6. I am not interested in dot net or any other. Very small program. The main problem of matching LINE OF SIGHT of Poin to Point WiFi long range radios is, when you are trying to find the signal coming from miles away, you need to pin point the LOS, the second you receive the signal. So, it is most important and comforting if I get a alarm or some sort of signal on my computer the second it received the signal. Mostly the problem is even after receiving the signal, it takes time for handshake or authenticate. We don't want that. It can be a single form project in VB6. The second it received the signal, just make beep or some sort of symbol on a form. That's it. (You may use UDP.) We are trying use normat TP LINK POIN TO POIINT RADIOS. Most available in the market. If you want to use some thing else fine with us. Let us know the model number and brand if it available in my country. But it has to long range poin to point radio. Not point to multipoint Radio or Router. For a special reason we have to have this project in VB6. If it too much problem in VB6, Let us know.
