another posibility would be that he has a usb2 hub plugged into a usb1 port on his mobo.

True. Maybe even the other way around too.

Hi,
I bought a COM port programming book I understood some lessons and others I couldn't.I bought also a USB programming book.But I don't know how to get use of it.I mean what is the next step after buying the book to make usefull projects especially for business(gain money for a project you made).May any one explain to me how to make these books useful?.I made a project using the parallel port before but it was not usefull enough to make a business project and it was not complex like the com port and USB port programming.
I am too late but i will never give up

 You have to understand the material to make any use of the information in the books!
If you don't understand the material, you've got some more research to do, don't you?

I think it will be better to determine a goal for reading the book before reading it.At least what kind of projects I could make after reading these books?Then there will be a reason and a desire to finish the book.

You bought the bloody things, didn't you?? Or are you in the habit of spending money on books and just putting them on the shelf, never cracking the covers?

That depends on what's in the books!!

You are right...it depends on what's in the book.I only wanted to ask about the projects that could be made depending on the USB and COM ports programming books in general  .Thank you for responding to my questions .

Basically you need an external piece of hardware to talk to to use either of those. Unless you're working for a hardware company you're unlikely to need to talk directly to the device instead of using a defined API that does the lowest level for you. Going forward RS232 support on mobos in on life support and fading fast, any new development is almost certain to be USB. That said, last summer, I did write a com port program to talk to a blackbox that the vendor wanted an exorbitant amount of money for a very badly behaving control app. In that specific instance, in house turned out cheaper and better, but that's not a very common situation to be in.

First,
I am happy to find some one who have experience in this field.
Second,
Even Iam not working in a hardware company I hope to work in that field.May be because I was studing a bit about this field in the university.Can you tell me about a device which I can start building a USB program on?
You have mentioned 'Going forward RS232 support on mobos' .May you tell me what do you mean by mobos?

Find a USB device that has low level documentation on how it is controlled and write a program to implement the interface. I've no idea where/how to do this, I'd suggest checking the websites of manufactures of USB devices you already have. IIRC most MP3 players have a standard interface this might be a good place to start.

motherboards. Most newer desktop boards don't have RS232, parallel, or Game/Midi ports any longer. I wouldn't be surprised if PS2 mouse/keyboard ports stare disappearing from desktops soon as well.

I also want to learn more about USB programming of devices and found a good training tool in the Velleman USB-kit. It comes with drivers and sample programm and has a dll for programming in Visual Basic.
website is Velleman.be, its a belgian company with distributors abroad.

Hi..
I like to ask you if you know any place(Training center,University) to learn Hardware programming so I could work for one of the Hardware companies or at least make a project for a small organization that sales devices(like GPS Tracking systems devices).

As others have mentioned in this thread, serial ports are fading fast. I can state however, that they are still very prevalent in the Printing Press Industry and when you get down to chip level programming, serial ports are still around there (they are easier to implement in limited memory space than a TCP/IP stack).
As for projects, you will have to look at this from a device point of view. Ask you're self "What type of device do I want to be able to control or communicate with? And what does that device do?".
Example project: Connect your phonograph to your computer through a USB port.

Hi,
I'm looking for a new keyboard and mouse for my computer.
It needs to be wireless - does anyone have any suggestions?
These are the programs I use the most (just in case it matters):
- Visual Studio
- Outlook
- Word
- Internet Explorer
- Excel
Regards,
Kenneth

The only way your going to find the "best" keyboard is to go and see what your hands feel like. There are people who swear by those split keyboards that are supposed to be ergonomic and easier on your hands. Then there are those who think they're crap. I'm a member of the latter camp. You might not be. Just go and try 'em.
I use a Logitech G15 myself. Those extra buttons and the center display can be used for more than just games!

I second dave, its a quite personal thing. I dont think the split ones are good, cause when switching keyboards it takes a few mins to adjust. I use a saitek eclipse (the first one) it has nice soft quiet keys, and one of them adjustable wrist rest things,

(they keys shine a nice blue, the new ecplipse II can switch between three colors)

You're right - there no such thing as a "best" keyboard that fits everyone!
However - I was really looking for some information on the keyboards that other programmers are using... That probably wasn't clear in my post - my bad!
I've been looking into getting a Logitech Cordless Desktop MX - I've had it before and it was great. But unfortunately Logitech ain't making it anymore - so I might very well be giving the Logitech G11 a try... It should be like the G15, but without the LCD-display. Are the keys "soft" on the G15 can you use the extra buttons for macro's in e.g. Visual Studio and other programs that I might like - or are they locked to a fixed number og programs?

Kenneth

The keys are programmable! You can create keyboard macros with teh Logitech software and play them back at any time.

So I went with the G11 and have had it for a little over a week now - and so far it's been great.
I was wondering if you have some great tips on which kind of keystrokes/functions you have "macro'ed"? I'm especially interessed in those you're using in Visual Studio...

Oh, just stuff I use alot. A few things I use frequently would be a template for adding SqlParameter objects, class templates, some methods I use pretty fequently, ... Basically, anything you would use a code snippet for that you use frequently.

is it posible running windows XP to detect if the screen monitor (any type, size, brand) is connected to the ac power line and for how long it had it been in that state (and keep a log file of all changes of ON-OFF state)
|
|
|
|
|
Yes, but the monitor would need to have a usb port, and you'd have to know how to detect the monitor via usb, blah blah blah.
No, I don't know specifics, but the method I described so poorly seems viable to me.
