Hello ah_jiang_9 wrote: how can i possibly display graphics object? There is a Paint event -or a similar event- that you have to handle in your control to draw whatever you want. In it's PaintEventArg.Graphics you can draw your image as you like. Some controls don't fire this event as they draw there own interface. Yet you can inherit from them or customly draw them. This depends on where you want to draw your graphics object ah_jiang_9 wrote: i created it from a picturebox and i added something to the picture but i have no idea on how to display it Why? It's as simple as these three lines: pictureBox1.Image = new Bitmap(pictureBox1.Width, pictureBox1.Height); //Make a new image in the box Graphics g = Graphics.FromImage(pictureBox1.Image); //Make graphics g.DrawLine(Pens.Black, new Point(5, 5), new Point(30, 30)); //Draw Regards:rose:

Have a look at 32feet.net Peter Foot has spent alot of time getting the windows bluetooth api into an friendly dll. Have a look, it also has lots of examples. Only drawback is that you have to have XP Service Pack 1 (or any operating system that comes with the Microsoft Bluetooth Stack) and that you have to uninstall your current drivers if they are not Microsoft. It also has all the support for the MS Stack enabled pda's and smart phones that run the compact framework. Gav

AFAIK, Bluetooth devices can be used pretty much as serial ports. You should see in your system properties if your bluetooth device, once installed, creates something like a virtual COM port, which you can use with the class SerialPort in .NET framework 2.0. ~~~ From Milano to The Hague, easy as it goes ~~~
