Well, thank you for noticing! 
As this is a searchable forum, this is how I think it should be done. Otherwise there wouldn't be any benefit for others.
Just following my own guidelines...

I attempt to use the kmdf to write a DFU(Device Firmware upgrade) driver and need to open/read an upgrade image (an normal file on disk) in the driver (maybe in the callback EvtDOEntry()). Is this possible to do this? Any suggestion would be appreciated.

It can be done (Using files in a driver[^]) but it must run at passive level. Also, if your driver is boot load, be careful that the storage stack and file system has been loaded before you.

Hi
I am working on OPOS with VS2005(coding in VB). Iam trying to connect driver through PosPrinter. I have a OPOS manual but I cannot get help as how to synchronize the .NET commands and OPOS commands. MSDN sites also did not help in this matter.
I require help as to :
(i) How will I include OPOS commands while coding in .NET ?
(ii) What VS2005 notations will eb required ?
(iii) Finally what are the advtgs. of using OPOS ?
Could somebody help me with the code ?

Dear friends,
I have a query. And I hope you can solve it.
You are heartily requested to help me.
I have to make an application for employee attendance recorder using THUMB (Finger Print) scanner (Biometrics). using VB.NET
I dont have idea about that hardware and how to relate with our application.
First of all I system will keep Database of thumb impressions of all employees.
Then employees will note their attendance by their thumb on scanner. System will identify and match the thumb print.
If it is matched then corresponding employees record will be updated for (As he/she is present for that date) otherwise it will give an alert that invalid employee,
I think you got my theme. You have solved such problem. and I hope you will cooperate me this case.
You are kindly requested to guide in this.
Thanks.... I am waiting for your reply.
Thanks,

Hi,
I have a Intel Core 2 Duo Machine that keeps on resetting at irregular intervals. I have reloaded the OS but to no avail. Then I loaded the Intel Hardware Monitor and see that I may have two problems:
1. The CPU is a bit Hot (57 Deg Celcius - according to the Monitor this is yellow alert)
2. CPU I/O Voltage is a bit Low at 1.26V (Should Be 1.5V)
It Would seem that I need to replace one or more fans in my box and also replace my Power Supply (500W).
Is my deductions corrent and is there maybe anything else that I should look at?
|

Sounds good to me. Although I think its more likely to be the overheating thats causing your problems. I would replace the fans first, and if that doesn't help then go ahead and replace the power supply.

If you have a homebuilt/small shop built box you might have an option to adjust the voltage in the BIOS. If only one voltage is off significantly it's your mobo's power modules that're bad not the PSU. The PSU only provides +3.3v, +/-5, and +/-12V to the board. The various lower voltages that the chips require are produced by the the mobo itself using DC-DC convertors.
You know, every time I tried to win a bar-bet about being able to count to 1000 using my fingers I always got punched out when I reached 4....

First you should check you power supply. I recently had a similar case with some weird values at voltages.

How can I connect to a scanner from my application and scan and save file in .jpg format? Can any 1 help? I am trying ti do this using C#.
|
|
|
|

If you want, I'll show you how to do this using VB.NET and one DLL.
And if you good at C#, it is not difficult to convert VB.NET to C#.

Please sir show me the way. It would be very kind of u.

Are devices (storage devices) that have multiple path I/O avialable for Home use What I mean is in price etc.....

I try to get them use WMI, but in WMI the Win32_TemperatureProbe's CurrentreadingThe property's presence is reserved for future use.
I find somebody get the cpu and mainboard’temperature us acpi.
how to get the temperature?
|
|
|
|

Never use WMI!!! For work with hardware or other devices that are always different on different computers, you need knowledge in Assembler and C++. To get information from sensors you should at first: determine physical address of sensors, then use I\O to read information, this is formula of universal programm that read CPU and mainboard temperature on any computer where sensors installed of course!!!. For me it is impossible to reach how to do it. I know how to do this by theory, I have much search in google and MSDN but my results aren't good.
If somebody knows how to do it, please write some examples.

I've been working on a microcontroller project that routinely dumps status and debug information out its serial port. It always does this, regardless of whether or not anything is listening or even connected to the port.
If I boot my PC while it's connected to this thing, Windows XP often interprets the status and debug messages as mousespeak, installs a serial mouse driver, and then tries to interpret subsequent messages as if they were coming from a mouse. This results in occasional wild cursor movements and random mouse click events, as though some spastic ghost was trying to operate the mouse.
I can effectively kill the spastic ghost by uninstalling the serial mouse driver after XP has booted, but the problem comes back the next time I boot the machine.
If I disable the serial mouse driver instead of uninstalling it, the problem goes away and stays away, even after I boot again. This would be a fine solution if it was for just me, but I want to deploy this system to customers, and it would not look good at all to try to explain all this to them and to have them dinking around with mouse drivers.
I discovered (by Googling) that Windows supports a /NOSERIALMICE option within the BOOT.INI file that's supposed to prevent it from automatically detecting serial mice. I tried this option and it didn't work.
A second round of Googling revealed that /NOSERIALMICE was for Windows NT and that it's been replaced in Windows XP with the /FASTDETECT option. Unfortunately, /FASTDETECT didn't work for me, either. (In fact, it was already present in the BOOT.INI file when I started all this.)
Apparently this is not an uncommon problem. For example, quite a few links from Google described similar behavior when booting a Windows computer while it's connected to a talkative GPS device. These same links recommended /NOSERIALMICE or /FASTDETECT as the solution, but they don't seem to have any effect for me.
Can anyone suggest a different way to solve this problem? Or perhaps a hint about what I might be doing wrong with /NOSERIALMICE or /FASTDETECT?
Thanks,
rmac
