Re: connecting LED to parallel port's input data pin Muammar©11-Nov-06 21:29 Muammar© 11-Nov-06 21:29  hi, 1. connect a light cell to the input port and the ground 2. face it with the led powered from an output pin or you can connect the output pins to a relay "coil" and the relay "switch" back to the input ports but be carefull. or you can skip all the hardware parts and do it programatically Device Driver articles regarding. 1-Aug-05 4:31 1-Aug-05 4:31  Hi, If any one backed up device driver articles material published in codeproject, can you please mail them to jagadeeshrpind@yahoo.com Thanks in advance. jagadeesh Re: Device Driver articles regarding.

I want to test the RAM present in any system. I need to test it considering the paging system present. Thanks, -Tom Re: RAM tetsing Alexander M.,1-Aug-05 1:24 Alexander M., 1-Aug-05 1:24  Use memtest86 or any other of these memory testing programs. Coding one yourself doesn't make sense if you don't know how hardware programming for x86 protected mode works. When you check for memory errors in windows you won't be able to check the whole physical memory because of paging! Don't try it, just do it! Re: RAM tetsing Anonymous3-Aug-05 1:55 Anonymous 3-Aug-05 1:55  Ya, I do have memtest86. But how do I verfy about the test result. Whether its proper or not?. Please point me some link so that I can cross verify it. -Thanks in advance -Tom Re: RAM tetsing Alexander M.,3-Aug-05 8:05 Alexander M., 3-Aug-05 8:05  When memtest86 displays errors then there are errors, what is the problem with it?

Once I added the NNTP and SMTP components, the install proceeded almost smoothly, except for the Information Store service which failed. Anyone has any idea how to get that up and running on a new install? Google failed me for the first time ever.

What kind of a virtual Server do you use? I think there´s a problem with hardware device drivers. Many (cheap) Virtual Servers simulates a new system in a running system in that way, that hardware was simulated too. -> e.g. if your real systems uses a radeon 9000 graphic card, the virtual system uses a (very old) standard graphic card. I think that´s the same with your network, sound and other components. The virtual system only maps the input to output of your real system and across. So I think there are many problems to use specific applications like ExchangeServer etc. Very good (and expensive) virtual systems will solve this problems, but not in 100% Ciao Norman-Timo Re: Windows 2003 Exchange Server Bassam Abdul-Baki5-Aug-05 1:51 Bassam Abdul-Baki 5-Aug-05 1:51  Microsoft Virtual Server 2005 for testing and development. We have SharePoint, IIS and other servers set up this way. Exchange was the first to give us problems.

How I can manage standart DV device from my programs? For example: send "record" command to videorecorder (i etc. To simplify task: I don't need transmit/receive video and audio data, only commands. Re: Managing DV device (IEEE 1394) Alexander M.,28-Jul-05 9:17 Alexander M., 28-Jul-05 9:17  Have a look at the DirectShow SDK. Microsoft does provide information about how to use the DV driver.

Can someone please tutor me on how to do the calculation: Take for example: p=7, q=11 and a proper value of e to encode text "OLAJIDE", I translate each letter to be: O=15 L=12 A=1 J=10 I=9 D=4 E=5 How do I apply the decrption/encryption to recover the original plaintext?

Re: Implementation of RSA Mike Dimmick26-Jul-05 8:08 Mike Dimmick 26-Jul-05 8:08  Details of the RSA algorithm[^]. If you're interested for theoretical reasons, go ahead. If you're trying to implement it yourself, don't bother: use a tested, FIPS-approved implementation. On Windows, from C++, use the Cryptography API[^]. From Visual Basic or a scripting language, use CAPICOM[^], the COM wrapper around the Cryptography API. From the .NET Framework, use System.Security.Cryptography.RSACryptoServiceProvider[^].

The very good tech support guy Tony did the trick by installing the generic intel sound card drivers. If your Thinkcenter has intel sound card try installing generic drivers, you'll get the most basic sound I/O. Farhan Noor Qureshi Re: Windows 2003 sound card drivers Alexander M.,25-Jul-05 9:03 Alexander M., 25-Jul-05 9:03  Google for it. Maybe there are different versions of that driver on the net.

When i installed WindowsXP, it set the drive letter of my primary hard drive to I: That kinda sucks, and 4 cardreader drives are C:, D:, E: and F: And i have Zip-drive with G:, and a DVD-writer with H: Does anyone know how to change all these drive letters Any help is appreciated! Re: How to change drive letters? Dan Neely22-Jul-05 9:24 Dan Neely 22-Jul-05 9:24  I'm not sure offhand, but would advise against doing it until you've got time to reinstall all of your software, and possibly your OS as well. When you rename your HD you'll hose a mess of shortcuts and saved paths. You can fix the start menu without too much pain, but hunting down all the entries in the registry and ini files would be a nightmare. In addition some apps with more paranoid security settings will asume they're not on the same system anymore and demand you provide thier serials again, so have those ready as well. Re: How to change drive letters? [Marc]22-Jul-05 9:49 [Marc] 22-Jul-05 9:49  Well, nothing is installed yet (only windows and some drivers). I once got a program with the installation-cd from the zipdrive, that could change all drive letters. But i lost it If i reinstall the OS, don't you think windows will make the hard drive I: again? I got some articles from support.microsoft.com, but i also read some stories that the system became unbootable. I keep my fingers crossed... Re: How to change drive letters? Dan Neely22-Jul-05 10:10 Dan Neely 22-Jul-05 10:10  Windows should fix it's own things when changed (I hope) but I remember doing a drive letter change once not sure if ut was under 98 or 2k, and practically ending up doing a full reinstall afterwards. You might be able to specify drive letters at OS install time, I don't know. I'm assuming you've got a real OS disk. If you're limited to an oem reformat+install factory image abomination all bets are off. Re: How to change drive letters?
