SCSI devices compatibility with my server Joan M16-Sep-09 3:36 Joan M 16-Sep-09 3:36  Hello all, INTRODUCTION/SUMMARY: the backup tape device on my server has died... Now I must buy a new one, and I was having space problems in my ULTRIUM 448 tape I was thinking on replacing it for a newer one. The problem here is that the people from HP don't want to ensure me that the newer devices will work on my server. QUESTION: The device that I own seems to use "SCSI Ultra160 LVD". Can I replace it by another device that uses "SCSI Ultra320 LVD"? As always, thank you in advance.

But the HP people can't tell you that, in case you would belong to the five percent of the people that it doesn't work for. And make sure that you have the right cabling and that the connector on the new device is the same type as on the old device. Personally I always buy a dedicated controller (and cable) for the backup device to make sure there are no problems with neither the backup nor the harddrives. Ask HP for recommendations. UPS turn on computer Mekong River15-Sep-09 21:55 Mekong River 15-Sep-09 21:55  Hi, does anyone know any UPS which could turn on the computer automatically when the electricity is available? Thank in advacne!!! Re: UPS turn on computer Dave Kreskowiak16-Sep-09 6:13 Dave Kreskowiak 16-Sep-09 6:13  Any modern BIOS on your motherboard should be able to do that by itself. I don't know of a UPS that will. All it can do is supply the power and inform any connected device about the state of the UPS. It's up to the machine to maintain it's power state. Every ASUS motherboard I've had has a "Power State" setting with an option of "Last AC state". If the power on the machine was on, when power came back, it would turn itself back on.

Re: UPS turn on computer Mekong River16-Sep-09 16:53 Mekong River 16-Sep-09 16:53  Dear Dav, Thank you very much for your answer. I will try to check my computer BIOS setting. But I think it won't work because this computer is a little bit old (one purchase in 2003 and another one is purchase in 2007). Thank for your answer!!!

I am attempting to add USB support to a custom board. I have written a simple console test program that Uses WinUsb_WritePipe, Read Pipe. All is fine. When I incorporate the headers and calls into my legacy app I can;t get it to link. I either get duplicate symbol defined _WINUSB_TEST or unable to find uuid.lib, or a few others depending the order of the includes. I should note I am statically linking MFC, building a debug build, and the wrapper USB class is usigng overlapped IO and is Multi Threaded (a seperate thread handles the IO with Thread Safe Queues buffering the data. My gut tells me this is an incompatability with the libraries. Microsoft stopped supporting the SDK for VS6 in 2003. The DDK is 6001.1802. I see a couple of options... Seperate the WinUsb code into a dll and hope the lib generated will link in with the main program. Recompile everything using VS2008. I have been avoiding this for 2 reasons. 1. I have experimented with VS.net, 2003, 2005 and MFC support seemed to get worse as did the GUI's. 2. The real reason. THe programs combined have nearly 500KLocs of code. There are a lot of CStrings and the scope of x in for(int x=0; x < y; x++) statetents. All of which are problematic with the new compilers. Any suggestions or help where I may be missing the boat would be greatly appreciated Re: WinUsb VS6 C++ Compatability bolivar12310-Sep-09 9:03 bolivar123 10-Sep-09 9:03  Some suggestions if you decide to build it all in VS2008..... The VS2008 CString class has a few quirks that were not there in VC6. The new MFC CString class is a lot more strict about index parameters going into functions like Mid, Left, Right, etc. What I ended up doing is derive my own subclass from CString and implement my own Left, Right, Mid, etc. handlers where my handlers would validate the index parameter(s) before calling the base class CString functions. I also did a little compiler gymnastics in redefining CString to CMyCString so as to not need to change every reference to CString in my project. As for the for scope problem, there is a compiler switch that overrides the for scope compliance rule. Use the /Zc:forScope- compiler switch to turn off the for scope checking. Out of curiosity, why are you statically linking MFC in a debug build? Re: WinUsb VS6 C++ Compatability Parker M cCauley10-Sep-09 13:11 Parker M cCauley 10-Sep-09 13:11  I statically link the MFC DLL in release mode because I have found it makes deployment more robust. This program started with VS 1.52 if you can believe that, and has morphed and been factored, etc. Major Requirements creep. Over the years the differences in mfc dlls that were on win 95, 98, 98se, etc caused support issues. I am not really sure why I an doing it in the debug version to be honest other than for consistency. I have tried it both ways and it doesn't seem to make a difference. Is there a reason not to statically link the MFC DLL in debug mode? Back to the original question, I am thinking that using a dynamically linked (loaded) dll might get around the issue? Your thoughts? Computer still prompt to set date and time Mekong River9-Sep-09 17:40 Mekong River 9-Sep-09 17:40  Hi, my computer is running out of CMOS battery while its first use around 4 years. Then I bough the new battery around 4 month ago. Last week when i turn on my computer, i found that the date and time is not set. I think the battery is running out so I purchase the new battery. But after I replace to the new battery and set the date and time after I turn off and turn on again its still ask me to set the date again. So I think this is not relate to battery. Could anyone let me know what is the cause of the problem that cause my computer to prompt for date and time setting everytime that I start up my desktop computer? Thank in advance!!!

Connecting to a wireless router which is not connected to any pc it directly connected to the outer unit which is getting signal , does this router would have any ip address if yes then how can i get /ping well i tired ipconfig and stats are dhcp enabled : Yes autoconfig. Enables : Yes IP Address : 192.168.0.6 and it has DHCP Address and DNS Address but this is my pc config. how can i get to know abt the ip address of router Best Of Regards, SOFTDEV Sad like books with torn pages, sad like unfinished stories ... Re: wireless router ip address Richard MacCutchan8-Sep-09 12:21 Richard MacCutchan 8-Sep-09 12:21  The IP addresses listed under DHCP/DNS should be the addresses of the router. Assuming you are on Windows you can find this by viewing the properties of the wireless network connection for your system.

What's a device driver. _80865-Sep-09 2:56 _8086 5-Sep-09 2:56  Ok I googled the basics. Don't worry. But still I'm not getting it. That's the problem. Please see if I'm getting it right. First let me explain a situation without Device Driver: ANY device that wants to be controlled through PC has a firmware written on top of it(On the device side itself). The devices gives us the option to control through PORTS. like serial/USB. We can control these devices by knowing the f/w spec. If we know the firmware spec, we can send direct commands through a port application and communicate with device. For example, I create a RS232 application and ask the printer to do any job I want assuming I know it's firmware spec. Here no drivers are needed. With Driver: When do we need a driver? If we want any application to talk to the device. Right? So we get the firmware spec and implement all I/O in a common driver dll and we keep this port I/O implementation functions into the driver and the OS maps the application calls through this driver right? How does this work? Can I write my own device driver to control the mouse? Can you explain/give link to know the sequence? Please Don't give examples with driver frameworks. I want to know the underlying basics. Thanks in advance. ---------------------------- 286? WOWW! Re: What's a device driver. Luc Pattyn5-Sep-09 3:48 Luc Pattyn 5-Sep-09 3:48  without a specific driver your app might be able to interact with a peripheral, provided the peripheral uses a hardware interface that is supported by some general-purpose driver (e.g. for serial ports), and you implement all the peripheral-specific stuff yourself inside your app. That may solve the problem for one app using a (simple) peripheral one at a time. with a driver you can use peripherals that could be shared (e.g. your LAN) and where incoming data gets to the interested party, you can apply protocols that need to be implemented only once (e.g. TCP/IP), and you can easily isolate your apps' problems from the drivers' problems. Would you like to have each and every app on your system to fiddle with the sectors of your disk?
