    Either amplify the file ("make the file louder") or try to find out which volume-setting the modem-output uses and increase that programatically. For example: you can set different volumes for files played from CD, files played via line-out, etc. I guess (and thats just a guess) that your speakers have a built-in amplifier (e.g., the speakers have a power-cord and an internal or external transformer) and thus what you hear on the speaker is amplified by the speakers. Thats why it sounds too weak when played unamplified (as it probably is on the phone line). Cheers, Sebastian -- Contra vim mortem non est medicamen in hortem.

    Unless you need some of the specific features it has, no. At the same time, the $50 difference between an entrylevel board from asus/abit/etc and a similar looking board from someone like pcchips is primarily in the quality of components used, so you're trading away stability and hardware life expectancy. Unless your budget is badly strained this isn't a good idea.

    TVM. I managed to find a PDF on MSDN which details various chipsets and the feature support for DX9, which told me that yes, it will work. It's not the fastest card, and turning on all the game video features does slow it down, even on a P4 2.xGHz 1.5GB RAM system, but it's playable, which was the main thing. Steve S Developer for hire

    I dint get ur question.We can create symbolic link only inside the driver code.In our AddDevice Routine normally we do that using IOCreateSymbolicLink.To know more about this see DDK documentation. But for viewing the symbolic links available in ur system u can use tools Like WinObj,DevView or ObjView.This u can get from sysinternals.com or oneysoft.com. If u can give some more explanation on ur need i can try more. regards Vairavan System software Engineer TCS

    You can ask Windows to check all protected system files using sfc /scannow. Have your Windows CD ready. To extract a single file from the OS CD, use the extract tool. If you have disk corruption it's usually a sign that the drive or memory in your system is faulty. Use the Windows Memory Diagnostic[^] or MemTest86 (original[^], revised[^]) tools to check that there are no memory faults. If nothing shows up, replace the drive. Stability. What an interesting concept. -- Chris Maunder

    Yes, you can install a driver programatically. You can use setupcopyoeminf() or you can create the service key entry directly, and set the driver to autostart. Truth is the subjection of reality to an individuals perception

    DosDevices was the name of the user-mode-accessible namespace in NT4. In later versions of the OS this changed. From user-mode, replace \DosDevices with \\.. In C or C++ you will have to escape the backslashes, so use "\\\\.\\TestIOCTL". Source[^]. Stability. What an interesting concept. -- Chris Maunder

    steve, Thanks a lot for your reply. Yes, Maplin does operate in Ireland. A Cash drawer is electronically a simple but crude device. it consists of a solenoide to release the catch so that it opens, and a microswitches, which tells if it is open closed, or "No Cash Insert Present", i.e. the replacable plastic innards with pigeon holes for the Notes and coin is physically missing. Microswitches and Solenoides typically operate at power levels far greater than provided by PC in and out ports. Most microswitches in my experience need to operate at at least 24 Volt 5 mA, to avoid long term degradation such as Dirt and Corrosion. The sparking at these lpower levels helps to keep things clean. Most solenoides for Mechanical action in this type of application take at least 24V and 50 mA . This is dictated by the scale of mechanical rigidity required to deter casual vandalism. Again, Many thanks for your help. Regards BramVanKampen@aol.com LateNightsInNewry

    Actually, this also happens with capacitors manufactured by well-known companies with an intact QA-department. You can call this a case of capacitor plague ONLY if the capacitors fail spectacularly and prematurely. Since the capacitors contain an electrolyte and are rated for a specific MTBF at a given temperature, they can break if they are used outside their specified temperature window. If the capacitor is rated for 10 years at 30°C, it might well fail after 5 years in 35° or 2 years in 40°, depending on the specifications used by the manufacturer. The drop in lifespan is quite dramatic for a small increase in temperature, and the result can also involve ruptures at the predetermined breaking point when all the electrolyte is gone. This does not necessarily mean that the capacitor was badly made, but just that it was not designed to operate under this conditions. -- modified at 6:50 Thursday 17th August, 2006 Cheers, Sebastian -- Contra vim mortem non est medicamen in hortem.

    The Switching between User and Kernal mode, happens in the background, and is an issue that User Mode programmers(as opposed to System Mose Programmers, which are mostly those working for Microsoft, writing the Next version of Windows), should have NO Concern about! There are ways of putting the system in Kernal Mode, but, I'm Not going to tell you, because you sound like someone who has not a notion about how windows works. believe me, I am saving yourself, and the friends to whom you propose to pass your software on, from a lot of hassle which would ensue if you went that way! Go the Windows Way, and use the WIN32 Api. Excepting special programs (e.g. Specialist Debuggers) Kernal Mode switching IS Not Needed!!! LateNightsInNewry
