Is it any good?

As a reference book, it's pretty good. The driver team at MS always seems to produce much better stuff than the usual MS drek. I've put off buying it for my personal library since I was waiting for the OSR KMDF book to come out. However, that STILL isn't out yet, so I think I'm going to have to bite the bullet and get it. I'm tired of borrowing a friend's copy.

See my reply to fat_boy for a WDF book. There is no "one" book or a "starter" book for drivers. It's a complex subject and the best way to start is to learn how the OS operates internally.

I have "Linux Device drivers" ( Alessandro Rubini published by O'Reilly) but I have not opened it so I am of no help here.
Maybe someone else can comment on this book.

how can i check whether the audio driver installed or not(in pc) for my vc++ application?
Thnx,

Take a look at setupdi functions. You can enumerate all the audio devices on the system , check their names, their status, and so on.

Hi all
I need to create a virtual drive with a fixed drive letter then I want to mount my external hard disk to this location of virtual drive. This drive letter should not change irrespective of reboot or changing the volume name of external hard disk also. I would like to write it in C or C++.
Thanks in advance.

Hello all,
I would like to have one PC running a mouse/keyboard simulation program that generates *real* mouse/keyboard input data on the USB port of another PC, effectively controlling the mouse and keyboard on the other PC without having to install any specific driver or application on the destination PC - it should just think it is controlled by a normal mouse / keyboard.
I already searched the web for quite some time on how to write such a simulation program, and either I do not search for the right key words, or it just is not possible (as u might see I do not have any clue of mouse/keyboard signals on the USB port up to now ...).
Does anybody have any clue on how to do this or where to look, or whether it is possible at all?
Many thanks in advance,
Das Ich

There is one problem: Just like using a VM, you'd have to lock keyboard and mouse usage to one specific computer, which probably isn't what is desired. You are much better off using a "desktop extender" like synergy, which allows you to span your desktop over multiple PCs with multiple operating systems:
http://synergy2.sourceforge.net/[^]
However, you are basically looking for a custom mouse / USB HID driver, which should be possible to implement. Even if it isnt the most sensible way to go.
Cheers,
Sebastian

Das Ich,
I'm looking into a similar problem right now. A hardware USB injector might help you (ellisys.com offer one, I think, and I've seen some others).
I tried to generate a keystroke inside the machine's driver, to affect a USB device between the machine and a keyboard (that device normally responds to keystrokes). However, it looks like I was stopped by the lower-layer drivers.
Please tell me if you find anything useful.
Regards,
brut.

So, I've managed to put my UMDF driver together and it actually works like a charm.
Now I'm wondering about the legal issues and the copyright for the source code.
The UMDF Skeleton sample is supposed to be some kind of a boiler plate for writing new UMDF drivers.
I haven't found any advise on how the files are supposed to be treated regarding copyright issues in the documentation/help.
My customer naturally wants to put their copyright notice in all files, but nearly all source files for the driver contains the Microsoft copyright notice.
Someone been there before?
Any ideas?

re-write the microsft source files so they are sufficiently different.

No prior post on CodeProject has made me laugh spontaneously such as this one!
Seriously, I was hoping you would answer my post, but I was also hoping somebody had stumbled on some kind of Microsoft statement that explicitly granted the use of those source files and how the copyright issues should be handled. I mean, the documentation clearly says the Skeleton sample should be used as starting point when developing new drivers and that can be interpreted as we are free to use these files. It is also described step by step how the source of the Skeleton sample should be modified in order to created a new driver.
Any other idea, beside writing to "the author"?

a heck of a lot of code is copied off the Microsfdt samples. Why? Because the documentation is so bad for a lot of stuff you have no choice.
So jut copy it, change the code structure a bit, and no court in the world could say it is the same, and therefore protected.

Well, can't argue with that.... 
Good point, thanks.

smart card drivers are a classic example. hardly any documentation and one code example in the DDK, which BSODs on 64 bit because of a difference in the 64 bit smart card system.

Hi All, Please tell me about the sockets. Is it a hardware or an virtual thing which we can open or close programatically.
A socket must be an hardware?

Hi
Iam working in OPOS PosPrinter with VB.NET(using VB code). I am generating a print i.e. a Sale Receipt issued to a customer. The bill is generated OK but the alignment is wrong. The first line is printed OK but from the second line onwards the variables are printed in wrong alignment, which makes the bill look ugly. I used "vbTab" for correction but with no result. Iam sending the code :
Dim srl As Integer = 0
Dim strProduct As String
Dim Product, Qty, Rate, Amount As String
While (sDataReader.Read)
Product = sDataReader("Product")
Qty = Format(sDataReader("Qty"), "#")
Rate = sDataReader("Rate")
Amount = sDataReader("Amount")
srl = srl + 1
iprn.PrintNormal(CurrentStation, "" & srl & "" + vbTab + ESC + "|rA" + " " & Product & "" + " " & Qty & " " + " " & Rate & " " + " " & Amount & "" + vbCrLf)
End While
**DEFINED IN A SEPARATE MODULE****
Public CurrentStation As PrinterStation = PrinterStation.Receipt
It will be of immense help if somebody points out the changes to be made in the code.
Best Wishes ....... ARIJIT

My guess is that you are using a proportional font in the printer when you print the data.
Try a monospaced font instead, such as Courier New.
