Hello,
I was looking for way to enumarate applications systemwide that currently using serial ports, let's say to get PID of who currenly has open COM1 or COM2... Actually I'm interested in the ports that are in use: "Port Settings->Advanced->Com Port Number" from "(in use)".
Thanks

Dear all,
I have a problem on how to get the PnP ID of a USB Thumbdrive. 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

Try replacing the immediate If statement with a regular If statement. Every time you go through your For...Next loop its adding

to your buf variable no matter what is returned by the IIF statement. Besides, buf = "Model: " & obj.Model & vbcrlf is replacing whatever you had you IIF statement return.

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.

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?

Hi ! I am looking for an example (sample code) about how to write a PC104 (ISA bus with new hardware form factor for embedded system) for Windows OS. Any windows can do the work. Windows XP Embedded, Windows CE or Windows 98.
I am new in driver design. I understand the WDM model but I saw that we cannot (or is very difficult) to design a driver (based on WDM) for ISA bus (or PC104) because it is not PNP. Some site suggest NT4 kernel mode driver.
What to do ??? Another thing, I know that writting driver for WinCE is different than other Windows Driver.
Thanks a lot.

The NT4 kernel contained most of what is known as WDM (win2k is just NT5 and XP is NT5.1). Almost everything except the plug and play stuff in fact. You can still use the old NT4 API, it is still there, your driver might fail WHQL though as some of these calls are 'disallowed' these days.
The cals in question are the ones that access the hardware, these days it is supposed to be done through one of the system bus drivers. However, you can still wirte your own bus driver, we do, and still pass WHQL, so it is a little murky in this respect.
Also, 2k and XP (NT 5 and 5.1) still run NT4 drivers, so you will have no problem if you use the NT4 DDK to write the driver.
If the device is a network device, and you just stick to using the NDIS api, then it will run on CE (and linux too as there is an NDIS wrapper for linux). If you need to call any of the standard API funcs though your driver will not run on CE.
Windows 98 supports a subset of WDM.
What sort of device is it, because it is fairly straight forward to write a monolithic (hardware to IO manager) driver of the ISA bus on NT4.
Nunc est bibendum!

HI
If anybody knows forums on networks,hardware which we can get solution immediately to our pbm. Bec' i am looking urgently like forums
thanks

hey dude,
firstly, if you want to get fast answers, start asking good questions...
moreover, you're looking for a HW forum, but did you ever seen that you were posting on it ?
at last, what do you want to know exactly ?

Hi all
I have Samsung CD-Rom SC 148A ,win 2K, my CD drive is sometime working and sometime notworking. recently i have downgraded my OS from Win Xp home sp2 to win 2k (due to install .Net).
After this degrading its works fine. from the last week itself only it makes trouble. When i saw device manager it shows the device is working properly.
My Internet connection is also breeze for sometimes.
Any body can help me to find out my pbm

Does it sound like it's spinning up, reading a little, stopping, then spinning up again?
I once had a Creative drive which was actually a rebadged Samsung. The disc is held onto the drive spindle by a metal spring clip. Over time this spring weakens causing the disc to fly up off the spindle as it speeds up (the spinning disc acts something like an aircraft wing). A temporary cure for this problem is to take the drive apart and bend the clip back into shape, but I found that it wouldn't last long like this. The permanent cure was to replace the drive with a Toshiba. The new drive has lasted five years in my possession and I've now sold the system on.

cd-drives hmmm... mine is not even spinning up some times, the cd can't be ejected anymore, the hdd light is on, and after some seconds, the cursor doesn't move anymore.
Don't try it, just do it!

Is USB 1.0 forward-compatible with USB 2.0?
I've read a lot of contradictory opinions on some other websites' forums.

Hope I have understood your question correctly. I haven't used USB 1.0 (I think) as even my oldest board had USB 1.1 on it.
If your question is asking if a USB 2.0 device can be used on a USB 1.1 port, the answer is yes, though of course it will only work at 12Mb/s and not USB 2.0's 480Mb/s.
The same if you meant plugging a USB 1.1 device into a USB 2.0 port.
Windows XP will even tell you when you have a 2.0 device plugged into a 1.1 port. It suggests using a 2.0 port to get maximum speed.

Thank you for the replay.
I need a memory stick for an old laptop which runs Win98, it would be good for backup and transfer of data. Unfortunately i cannot figure out what version the USB port is, so i have to think about 1.0 too.

The forward compatibility 1.1 has towards 2.0 is certain but i know nothing about the relation between 1.0 and 2.0 - in this order.

1. How can one find out, from which drive the actual program has been loaded from?
2. How can one find out, what kind of drive that is (floppy disk, RAMdisk, fixed volume, CDROM, etc.)? I found something re Stylebit of Removable Volume, but I did not find how to get it in C++.
Thanks

1) Parse the result from GetModuleFileName
2) Pass the result of 1) into GetDriveType

How do I erase or reset my virtual memory paging file? It would really improve my computer performance but I just simply do not know how. 
If you can help email me at lilbadboy52004@yahoo.com , or reply to the thread.
