Google for online discount codes. I saved 20%+ on my Lenovo laptop doing that 2 years ago. As long as you don't care about "voiding the warranty", you should upgrade memory and the hard drive yourself. Many manufacturers charge 100+% of the new part price to upgrade a component that might be a 10 minute install.

I lost track of the original driver discs for my machine. After I reloaded XP I only have USB 1.1. When went to Microsoft update site to update it to USB 2.0 (successfully). The Microsoft site did this by scanning my system and did the update automatically. There seems to have no way for me to install that driver manually.
I want to archive the USB 2.0 driver for XP on my machine, say save it to a CD. However, I don't know how I can download it from Microsoft site. Any ideas?
Thanks!

USB2 drivers are included with WinXP Sp2. So there are basically no manufacturer that bothers with making special drivers for USB2.

What I don't understand is I reinstalled XP, then put SP2 and SP3 on it. Both SP2 and SP3 were downloaded from microsoft.com. After that when I plugged a flash drive to the USB port I got the message:
This USB device can perform faster if you connect it to a Hi-Speed USB 2.0 port. For a list of available ports, click here.
This message appeared in a ballon box popped up from the system tray area.
After I put the update from Microsoft on, the message no longer appears. Why the SP2 that I installed does not contain the USB 2.0 driver?

Just a hunch: maybe the updater told you you had to reboot the system and you didn't?

You don't need to install SP2 if you're going to install SP3. Microsoft servicepacks are incremental.
Other than that I really don't have an answer. Sorry.

Regarding SP2 and SP3: I did install SP3 first, believing that it contains SP2. However, for some reason SP3 could not be successfully installed. The error message told me that SP2 had to be installed first (which is contrary to what I thought). That's why I installed SP2, then SP3.
I have USB2 working. I just wanted to save a copy of the driver so later if it happens again, I just need to pull out the archive to install the driver, instead of relying on a network connection and the availability of the driver somewhere in Microsoft's web site. Not a big deal. Thanks for your help.

I would call that cumulative.
incremental to me means you have to do them in sequence.

That means that the driver is installed and working. USB may be optimized for quick removal (in which case Windows doesn't cache much) or optimized for performance (and then Windows will cache some, but corrupts your drive if you yank it out while reading).
Default setting is "quick removal". You're getting a hint from Windows that the current setting is not ideal. Your USB device can perform faster - just as it says in the balloon.

Hello guys,
I jsut recently baught a Asus 23" Monitor and its working great, but my problem is that it is currently only working with the VGA port. The wirte is connected to the VGA port on the monitor and to a DVI on the Graphics card via an adapter from VGA to DVI.
Now i wanted to connect the monitor to the graphics card via a DVI to HDMI cable and when I tried this the monitor isn't displaying any picture it just says no signal. I tried DVI-I to HDMI and DVI-D to HDMI cables and still no difference. The only difference is that when i use the DVI-I to HDMI cable the monitor said no signal found and when i used the other one the monitor didn't even display a message.
My Graphics card is BFG Nvidia 9800 GTX if that makes any difference.
Can anyone please help me with the problem your help is greatly appreciated. Thank you from adavance.
Regards,
Christian Pace

Have you tried the button on the monitor to switch the input it's looking for a signal on? If it's looking on the VGA input you can send all the HDMI you want and it won't do a lick of good.

Yes OFC im not that stupid. When i change it to HDMI it says no signal found.

Hi...
we are used dongle in our application.. if once the dongle was safe remove .. that must be unplug and plug is manually .... i need first of all is possible to activate problematically not like unplug method... if is any command prompt, please share with me....
Thankyou

Please reply.
I have the source for This, but it is in Delphi 3, and too old for C# or C++
Can anyone convert/rewrite the source to C++ or C#?

Thanks, but i did get the LED's working, It is just the servo app sending the pulses that has a problem, the sevos are a bit shakey and moves a little every few seconds by itself. I got the Delphy 3 source, but cannot find delphy 3 anymore, and would love to get my hands on C# or C++ code that would move the sevo's.
Please if there is anyone out there that can help i would really appreciate this.

What I meant was, you could modify the code from the articles to suit your purposes. It shouldn't be hard if you know what kind of signal is required to drive the motor. I'm assuming you already have the interfacing hardware.

Please help with this
The problem is that there are no pic or basic stamp controller, it connects directly on the parallel port with only a resistor on all 8 data pins, and i do not have any experience with PWM (Pulse Width Modulator-or someting like this) pulse code, or to be honnest not much experience with Visual Studio 2008 at all, or hardware programming.
If someone will be so kind to help me just with some code to control 2 servo motors by sending a pulse to the servo motors, and make them move, even beter if you can use a up and down left & right arrow to control them , up & down for (servo 1) & left & right for (servo 2). I will then have an idea how to add more servo's for future use.
Please guys help me with this.
I am sure there are guys out there that will be able to do this in a few minutes, without even breaking a sweat.
Thank you.

Unless you are using an old operating system (DOS, Win98), I believe it is next to impossible to get the kind of timing that is required for driving a servo.
A servo needs a pulse between 1 and 2 ms long, repeated every 20 ms or so. There are some servo's that are outside this timing, but that's pretty general. At 1 ms, the servo will be fully counter clockwise - left, and at 2 ms will be fully clockwise -right. The control is getting the time somewhere in the middle and being able to repeat it accurately every 20 ms or so, until you want it somewhere else.
So....the problem is the newer operating system control the hardware through an abstraction layer, such that you no longer have machine level interface (i.e. direct access to the parallel port) or the IRQ's and interrupts, and therefore cannot guarantee when things happen. LED's are one thing since if they are on 20 - 30 ms longer than desired, who cares, but with a servo, it will be jumping all over the place.
Now, if you are running an old system, that is different, and it is possible in C or assembler, if you hook the interrupts and do the pin toggling yourself, and some of that information will be available out there. Otherwise, you will need an interface chip like the PIC or ATMEL, etc. That code isn't exactly trivial but is easier than using a PC as a PIC.
Not exactly the answer you were looking for, but you should clarify your hardware platform (hint, VS-2008 indicates XP or Vista), and understand the complexities of the hardware abstraction layers put in place to protect us from ourselves.

I think you can get hard millisecond level control in some realtime linux versions, if you're really determined not to do it the smart way.

Good day
Thank you very much for your posts.
I have managed to get my hands on a 4 servo app, i am sure it will work properly if it could be tweaked a bit, but i do not have the experience or Delphy 3. Please fillow this link to see the app that i am using.
It works fine & smooth, except for every few seconds there is a little shake. see: http://users.swing.be/philippe.jadin/servoen.htm[^] for how it was done, I am also using an app called porttalk to access the port directly in XP see here: http://www.beyondlogic.org/porttalk/porttalk.htm[^] . if anyone can help, let me know.
Thank you

I want to develop a dongle for my software. but I dont know anything about writing code to any pendrive's boot sector or making pendrive as dongle.
I also want to get some help about how to read the data from the prepapred dongle from my software,that is i want to know how to link the dongle with my software.
The s/w I have developed is a windows application in .net with C#
please help if anyone can.
Thanks in advance.

I don't know how you intended to make a dongle out of a pendrive.
Very simplified, a dongle is a piece of hardware that your software sends a serialnumber to. this serialnumber is compared to a value stored in a PROM in the dongle. The result is then sent to the program which is compared with the expected result. This whole process is done with hashing and encryption/decryption in both directions so that you can't find out the stored value in any easy way.
On a pendrive you can easily copy all of the content and thereby duplicate as many "dongles" as you need.
