Re: Almost hardware Anonymous14-Sep-05 19:29 Anonymous 14-Sep-05 19:29  It probably wouldn't be a bad idea to find information on the internet or in books that would help you get a better grasp of electrical circuits. As for implementing ground, the power of electricity needs somewhere to flow to. That would be ground. When you connect a positive or negative voltage to ground the power will flow. Between these you have your circuit or load. Re: Almost hardware Niklas Ulvinge15-Sep-05 2:08 Niklas Ulvinge 15-Sep-05 2:08  That problem was that one ground couldn't know about the other, and then how would the ground be able to know when to flow? I solved the proplem by 'cheating', as the ground I'm going to use don't have to be that specific. Now my system is really good, I'm going to implement kirchkorvs rule or something, can't remember the name... Niklas Ulvinge aka IDK hard drive serial number rolati6-Sep-05 0:06 rolati 6-Sep-05 0:06  i have heard that not all hard drives have a serial number. they all have a volume serial number, which changes with every format, but not a hard disk serial number. different articles say different things about this issue and i'm confused. so my question is: do all hard drives have a unique unchanging serial number or not?

Niklas Ulvinge aka IDK Re: How to write driver on Windows? fat_boy6-Sep-05 5:43 fat_boy 6-Sep-05 5:43  How much pain can you take? Do you have 6 months to spend (waste) doing this and still not get it right? If so, get the windows 2003 server DDK. Then buy Walter Oneys book, Programming the Microsoft Windows Driver Model. Then post loads of qestions to the relevant Google forums. BTW, what sort of wirless is it? GPRS, UMTS? or WLAN (802.11) ? Nunc est bibendum!

What kind of hardware is it and whet kind of network driver do you want it to look like to the system? Nunc est bibendum!

Roger Alsing31-Aug-05 1:45 Roger Alsing 31-Aug-05 1:45  anyone got experience with dialogics telephonycards? we have a problem where the card will get a "connect" event when we make a call even if the calee is not responding. i guess its because the card thinks that the swedish bussy/not answering tones are something else (?) any help would be very welcome Re: dialogics telephony card and sweden? Ray Cassick6-Sep-05 7:36 Ray Cassick 6-Sep-05 7:36  Try running through the PBXpert process to learn the tones in the area you are in then enable the resulting TSF file in the DCM for that board.

You are forwarding only the control connection but not the data connection. Easiest solution is just forget FTP and use HTTP for data transfers.

I will get the driveletter of the thumbdrive, say "J" but not able to assoiciate the PnP ID of the USB device in that particular drive (ie J), instead the code given below is giving PnP ID of all the mounted thumbdrives I will be very thankful if someone can get me the solution code: Dim obj, objs, buf Set objs = GetObject("winmgmts:").InstancesOf("Win32_DiskDrive") Set objFSO = CreateObject("Scripting.FileSystemObject") Set colDrives = objFSO.Drives Dim drv As String drv = "J" For Each obj In objs For Each objDrive In colDrives buf = IIf((obj.InterfaceType = "USB") And (objDrive.DriveLetter = "J"), _ obj.PNPDeviceID, "") buf = "Model: " & obj.Model & vbCrLf buf = buf & "PnP Device ID: " & obj.PNPDeviceID & vbCrLf msgbox buf Next Next End Sub thank you Dinakara K CAIR Bangalore Dinakara K CAIR, Bangalore Re: Get the PnP ID of USB thumdrive quacks_a_lot4-Sep-05 9:40 quacks_a_lot 4-Sep-05 9:40  Dinakara K wrote: buf = IIf((obj.InterfaceType = "USB") And (objDrive.DriveLetter = "J"), _ obj.PNPDeviceID, "") buf = "Model: " & obj.Model & vbCrLf buf = buf & "PnP Device ID: " & obj.PNPDeviceID & vbCrLf msgbox buf Try replacing the immediate If statement with a regular If statement.

Flat Panel LCD and KVM Jon Sagara26-Aug-05 12:11 Jon Sagara 26-Aug-05 12:11  I just got my new Dell 2001FP flat panel, but I didn't think about hooking it up to my KVM. Yes, I have to use the analog output, but that's okay. My question is, is it okay to switch between resolutions on an LCD monitor using a KVM just like I currently do with my old CRT? Two of my machines run at 1600x1200, while the other two run at 1280x1024. Are there any adverse effects from switching around like that? Is it just as safe as doing it with the CRT? Dumb question, sure, but it's a nice new monitor and I don't want to ruin it. Thanks, Jon Sagara As you may presently yourself be fully made aware of, my grammar sucks. Sagara.org | Blog | My Articles Re: Flat Panel LCD and KVM Mike Dimmick26-Aug-05 12:58 Mike Dimmick 26-Aug-05 12:58  I shouldn't think there'll be a problem. Your flat panel can only do one resolution anyway - in your case 1600x1200. All other resolutions are resampled up to 1600x1200 by the monitor itself. Your picture quality will be best if you use the native resolution. Presumably your older machines can't actually do this resolution? Stability. What an interesting concept. -- Chris Maunder
