a heck of a lot of code is copied off the Microsfdt samples. Why? Because the documentation is so bad for a lot of stuff you have no choice.
So jut copy it, change the code structure a bit, and no court in the world could say it is the same, and therefore protected.

Well, can't argue with that.... 
Good point, thanks.

smart card drivers are a classic example. hardly any documentation and one code example in the DDK, which BSODs on 64 bit because of a difference in the 64 bit smart card system.

Hi All, Please tell me about the sockets. Is it a hardware or an virtual thing which we can open or close programatically.
A socket must be an hardware?

Hi
Iam working in OPOS PosPrinter with VB.NET(using VB code). I am generating a print i.e. a Sale Receipt issued to a customer. The bill is generated OK but the alignment is wrong. The first line is printed OK but from the second line onwards the variables are printed in wrong alignment, which makes the bill look ugly. I used "vbTab" for correction but with no result. Iam sending the code :
Dim srl As Integer = 0
Dim strProduct As String
Dim Product, Qty, Rate, Amount As String
While (sDataReader.Read)
Product = sDataReader("Product")
Qty = Format(sDataReader("Qty"), "#")
Rate = sDataReader("Rate")
Amount = sDataReader("Amount")
srl = srl + 1
iprn.PrintNormal(CurrentStation, "" & srl & "" + vbTab + ESC + "|rA" + " " & Product & "" + " " & Qty & " " + " " & Rate & " " + " " & Amount & "" + vbCrLf)
End While
**DEFINED IN A SEPARATE MODULE****
Public CurrentStation As PrinterStation = PrinterStation.Receipt
It will be of immense help if somebody points out the changes to be made in the code.
Best Wishes ....... ARIJIT

My guess is that you are using a proportional font in the printer when you print the data.
Try a monospaced font instead, such as Courier New.

How do I switch to a monospaced font? Where do I change, in the program or in the printer? Please give a step by step guideline.

My computer is festooned with USB ports and I thought they must all be 2.0 devices, but every time I plug in a new (for example) external hard drive I get a message to the effect of, "Errr, Dave, you know you could get a whole lot more performance if you plugged this device into a USB 2.0 port". It then displays a list of potential ports I could use.
The problem I have six ports coming off the MB, which I assumed were USB 2.0, two on front and four on the back, plus a four-port PCI USB card that I could have sworn was a USB 2.0 (the packaging was disposed of immediately after installation), but I can't tell which device in the list is running on which hardware port, much less if any of them are actually USB 2.0.
Is there any way to determine the capabilities of these ports? I can't seem to find anything useful from Device Manager.
Thanks for any advice.

It's a bit of a dirty approach, but here goes:
In USB 1.x, the programming interface from the PC to the USB controller wasn't standardised. Intel came up with one solution they called 'Universal Host Controller Interface' (UHCI) but there's a second solution defined by Compaq, Microsoft and National Semiconductor called 'Open Host Controller Interface', OHCI. I think this was partly a technology issue - OHCI reportedly requires less software and generally lower CPU usage - but also a licensing one.
For USB 2.0, the software people put their collective feet down and insisted on a common controller interface, which is called Enhanced Host Controller (EHCI). In Device Manager, you'll typically see USB 2.0 controllers listed as USB2 Enhanced Host Controller.
You can always find how a device is connecting to the system by selecting View, Devices by Connection from the menu. By expanding the tree, you can see whether a USB Hi-Speed device (connected to each port in turn) is connected to an EHCI or to a UCHI or OHCI controller.
This is further complicated because physical ports can be 'connected' to both an EHC and a UHC/OHC. The system works out whether the device is requesting Hi-Speed (480Mbps) and if so, 'connects' it logically to the EHC. If not, it connects it logically to the UHC or OHC. That's why I suggest using a Hi-Speed device. Most modern integrated USB controllers actually do both in one chip or subsystem of the chip and the UHC or OHC presented to the OS is generally referred to as a virtual device.

Hey, thanks very much for all the information Mike! I can see clearly now that the computer I was wondering about doesn't have any USB 2.0 ports at all. Armed with the info you gave me, I checked another computer and found that it has a bunch of USB 1.x ports, but it also has one EHC controller. So now my only other problem is to figure out which hardware jacks are fed by which controller. The one USB 2.0 controller says it has 8 ports, but there aren't that many USB jacks on the computer, so I'm assuming that not all of the hardware ports are actually coming out of the controller chip to jacks.
At least this gives me more insight into identifiying what hardware I've got. Thanks again!

As I remember there is an option to enable USB 2.0 configuration in BIOS setup.
Maybe you have 2.0 ports but they are not enabled, that's why when you plug your usb device you are getting that pop-up message.
Regards.

Use usbview.exe. It will show you all the ports, decvices and capabilities on your machine.

Little off the subject - I am looking for a easy way to convince windows that USB drive is a dynamic drive.
In past I plugged the drive intenally and mark it dynamic than moved it onto USB hardware. But since my current external drive is "sealed" I cannot do that without voiding the warranty.
Anyway, even when the USB drive is dynamic windows will regenerate it every time you turn the power on - no good.
Looking for a real dynamic USB hard drive "fdisk" program.

What I have:
- An external hard drive (2.5 inch 30gb from an old laptop in an external USB case).
- A laptop (three months old with single 200gb hard drive) running XP Pro that's fully updated.
- A desktop machine (2 years old with 2 IDE drives and 2 SATA drives) that is also running XP Pro that's fully updated.
Problem Description:
When I connect the external drive to my laptop, it works fine, in that Explorer sees it, and I can even change the drive letter.
When I connect it to my desktop system, it's seen by the device manager, and it shows up in the list of USB devices that can be disconnected (in the system tray), but it doesn't show up in Explorer, nor does it appear in the Disk Manager.<br />
Other Notes:
Jump drives work fine (I have three ranging from 512mb to 4gb) in both machines.
SOLUTION:
On my desktop machine, I don't have a front-mounted USB connector, so I have a USB cable that hangs off the front so I can plug in my jump drives. HOWEVER, I have a cable on the external hard drive, and I was just plugging that into the extension cable. This made the cable *TOO LONG* - the signal isn't strong enough to go 12 feet (beyond device recognition, anyway). Plugging the hard drive's cable into another USB port solved the issue.

I use a three footer for that, but I'll have to keep this in mind.

wow bad luck. the cable would have been the last thing i would have checked if the device was showing up 
i dread to think how much hair was lost/ money was deposited into the swear jar from this little experience

What threw me was that it would show up on the laptop and work fine. When I realized that I was using a longer overall cable length, I kinda figured that would be the problem.
