Thank you all!
it worked.
I knew that there is an option to reset but I was afraid to do that because I thought that there is a risk to lose the configuration and the passwort will not be change...
So another time-Thank you!

Hi all,
I have created a device independent driver. For which i want a application launcher. My drivers name is "TestIOCTL" and its symbollic link is "\Device\TestIOCTL ". I now want to open this driver file for which i have used the following code segment.
hDevice = CreateFile ("\\DosDevices\\TestIOCTL",
0,
FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL,
OPEN_EXISTING,
FILE_ATTRIBUTE_NORMAL,
NULL
);
The hDevice returns 3 thro GetError() Method meaning File not found. Can anyone tell me how to open this driver file.
Thanks In advance.
Regards
Kenny.

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".

I was given an application that calls a driver which also calls interrupts at H/W level in order to update that BIOS of a ceratin laptop. However, I was asked to develop the application in such a way that I won't have to install the driver manually anymore just to activate the interrupts for the BIOS update. Is it possible to do so and if yes, how can I proceed. The application by the way was made in Visual C++ ver. 6.0. Thanks.

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.

I need help transfering files between Windows(NTFS) and Linux(ext2)! I need a program or method for doing it.

If transfer of files is not too frequent then a FAT partition could help b/c both NTFS and ext2 can read/write to FAT.

Hi,
Can anyone tell if there is any software to create symbolic link for driver files in windows.
Thanks in Advance
Kenny
|
|

|

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.

Hi,
I have created a Device Independent Driver Code. It is working perfectly. All i need is a Application Launcher program. And that is where my problem starts. I am trying to create the file using the CreateFile Command. And it is always returning false. I have attached the code snippet below. Anyone who knows how to solve the problem please help me.
HANDLE OpenDeviceDriver(LPCTSTR szDriverName)
{
HANDLE hDevice;
TCHAR szFullName[200];
wsprintf(szFullName, "\\\\.\\%s", szDriverName);
hDevice = CreateFile (szFullName,
0,
FILE_SHARE_READ | FILE_SHARE_WRITE,
NULL,
OPEN_EXISTING,
FILE_ATTRIBUTE_NORMAL,
NULL
);
if(hDevice == INVALID_HANDLE_VALUE)
{
hDevice = 0;
printf("%x Error %ld\n",hDevice,GetLastError());
}
return hDevice;
}
With Warm Regards
Kenny

What's the return value from GetLastError() ?

The result of GetLastError() is 2

Means The file is not there in the specified path.I want to know what u or passing to szDriverName.

Which port? 
(In case you didn't realise the sarcasm, what type of port? I'm assuming TCP/IP here)

my machine (2.6 GHz celeron on an asus m/b) has just started locking up. after a few fruitless reboots i thought that the cpu might be overheating despite the lack of warning beeps and such like. i went into the hardware monitoring part of the bios and found that the all except the 12V rail were operating at about a volt too high. ie the 3.3V rail was at 4.3V and so on. and the fan RPM was not being displayed or the CPU/case temperatures. but if i moved the selection up and down, sometimes the voltages would right themselves and all the other settings would then display correctly. for a while, and then it would jump up again.
i figure that either it's a power supply problem or a m/b problem :->. but before i start trying to locate (or have to buy) a replacement power supply, has anyone else experienced this and what was the solution? ps. i'm not made of money

As for the Power Supply:
You can test the PS, but the results might not be the same as if the PS was under load:
Remove the PS from your computer. Disconnect all cables. Take the Mainboard-Connector. It should have 20 pins in total (if it does not, you will have to check the manual for the pin layout). Short Pin 4 to Ground with a piece of wire.
How to find pin 4: the pins are numbered from top to bottom in a row-first manner. The top is the part with the plastic hook. Example:
[code]
|-----|
1 2 3 4 5 6 7 8 9 10
11 12 13 14 15 16 17 18 19 20
[/code]
If shorted this way, the PS should start running.
Then try an measure the voltages (try formfactor or wikipedia for the appropiate pins).
IMPORTANT:
This is just my experience. I do take any responsibility for any damages caused to you or your equipment when following these instructions. If you do not know how to behave around electricity, DO NOT TRY THIS.
As for the MB:
Visually check the capacitors on your MB. They have a (usually) cross-shaped predetermined breaking point on their cap. The top of the cap should be flat. If it is deformed or broken, it is likely that they reached the end of their lifespan. In that case, you could either try and replace them with new ones (see IMPORTANT note above) or buy a new MB.
Cheers,
Sebastian

This is called Capacitor Plague and is NOT normal. See this[^] for more info. It's quite the interesting read and why I'm replacing about 1 motherboard a week where I work.

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.

I want to use Visual C++ for control hardware via RS232 or USB port.
Anyone know what is the good book or website which I can get the infomation about this issue.

Max++ wrote: website which I can get the infomation about this issue.
Google, AFAIK there are not many dedicated sites. The MSDN Library has a good article on reading and writing data to and from the COM ports (sorry can't remember the title). Most USB drivers come with something that will allow the USB port to look like an RS232 port with a higher baud rate. So generally all you need to know is how to read and write data to and from RS232 ports.
Regarding actually controlling the hardware you'll have to provide more information.

Can u give some more info reg ur requirements?.If u want to control ur hardware with RS232/USB u need to create handle to ur device then u can do read/write to ur device.For that u should know the command formats supported by ur device.Is it a printer/storage/camera or any thing else?.
If u give give more details i will be able to provide more info.
