I dont have multiple touch devices (had to buy this one in order to be able to test). Maybe i will have to test the parameters of the RegisterTouch...() method, although I am sure it wont make a difference. Its good to know that those messages will be translated to normal mouse messages. Thanks for your support so far!

Look at the Accord.Net framework. César des Souza described many functions in his articles on CP, start e.g. with Handwriting Recognition Revisited: Kernel Support Vector Machines[^]. The problem of hand writing recognition may seem unrelated, but I am sure that many aspects are shared with your tasks.

anyone?

I believe you to change the Setup/Initialization of the Port. Compare every single value. There are some samples at CP try different to get it work. Have you tried to write in loops??? //Meta-Code while( DataToSend() ) { Send16Bytes(); } GetLastError() is also your friend!!!:mad: Serial Port is a legacy problem so not so many know how to handle.

Glad to help. Cheers Steen. "To claim that computer games influence children is ridiculous. If Pacman had influenced children born in the 80'ies we would see a lot of youngsters running around in dark rooms eating pills while listening to monotonous music"

If this is true for vectors, then i will give it a try with vectors! I hope this will work better. Thank you. DKT

Yeah sure. I did that, and got it to work. I am having other problems with the trayicon, which caused the problem! I have an MFC app, where I wanna handle Messages, eg. a Buttonclick on the icon. I dunno how to do that. Who can tell me just the base. I can learn myself, but I need to know the base. For a normal app you make an endless loop checking for messages. But here? DKT
