I'll deliver an updated library/driver with new samples

It sounds wonderful. Will it be a dll, which can be used from AHK, or from pure C programs?

Couple of days ago,
I tried following C Codes;
But, it made Error messages, such as
""...bufferoverflowk.lib(gs_support.obj) : error LNK2019: unresolved external symbol [email protected] referenced in function [email protected]""

VOID
KbFilter_ServiceCallback(
    IN PDEVICE_OBJECT DeviceObject,
    IN PKEYBOARD_INPUT_DATA InputDataStart,
    IN PKEYBOARD_INPUT_DATA InputDataEnd,
    IN OUT PULONG InputDataConsumed
    )
{
	PDEVICE_EXTENSION   devExt;

	switch (InputDataStart->MakeCode)	
		{
		   case 0x01C:   						//	Return 		Keypad Enter

}

Unfortunately I am not at all expert in this area.
So, for the first time in my life time I downloaded WDK and tried to 'build -ceZ' stuffs..

The result is disastrous..

My intention was like this.

To Use additional PS/2 keyboard with full scan code under my control.
Which means that any of the keyboard scan codes should not the same one with main keyboard scan codes.

The final goal is to use additional USB keyboard with the same purpose.

Yorick, Maybe the best use of AHK was to write a prototype of a functional part of a large program, test it, tune its user interface, and then re-write it in a compiled language, like C. This does not work with static libraries, only with dll's. Also, if your really nice library was going to be used as part of another program, the need for installing low-level drivers in the client machine not pleasant. Is there any chance to do similar things without messing with the setup of the PC's of the users?

Dear, Yorick !
Can you help me out ? I am a prince in distress.

I know the codes above are silly one, but it was what I can do best.
I used all the same file in C:\WinDDK\6001.18002\src\input\kbfiltr except the .c file (it is just patch work of others).

I posted this agony to some expert group websites in my country, nooobody was interested in.
Is it too hard to get there ? or they thought it is just waste of time to play with beginner ? I do not know.

Can you please make .sys file for me ? I guess that is all I need.
Many thanks.

[Hamlet]

Dear king's jester.

As far as I know, I need 6 files to complete building process.
kbfiltr.c (the only file I modified, I already posted in this article.)
kbfiltr.h
kbfiltr.inf
kbfiltr.rc
makefile
sources
Last 5 files are the same original ones in C:\WinDDK\6001.18002\src\input\kbfiltr directory.

I had error messages while "build"ing the kbfiltr.c file with WDK program-->
...\bufferoverflowk.lib(gs_support.obj) : error LNK2019: unresolved external symbol [email protected] referenced in function [email protected]
...\objchk_wlh_x86\i386\kbfiltr.sys : error LNK1120: 1 unresolved externals

I am sorry, but I think there is nothing I can do any farther.

Pls help me. I feel like bounded in a nut shell.

Thanks.

[Hamlet]

I got it. I got it.
Your advice was great one. Thanks Yorick !

I should have used all the contents in original kbfiltr.c file.
I used very small portion of that file and modified it and deleted all the rests. I was wrong.

As soon as I saw Your advice, I made new one.
Which has all the original contents and some of my own codes too.

Build it nicely.
It worked perfectly !!

Thanks again Yorick, I am pretty sure, you are born again !!!


And I have to try it out with two USB keyboards.
Umm......

Bye..

[Hamlet]

Thanks, Nyo !! (for USB hints)
Thanks, Yorick !! (for Building process)
Thanks, joelhewitt !! (for DVORAK codes)
Thanks, GeomanNL !! (for Extention scan codes and this posting itself)

It works with USB Keyboards too.
And you do not have to re-boot your computer,
if you want original one, you just roll-back or update it.
(with PS/2, you have to re-boot.)
It looks like it distinguish every USB port.

I am using 32bit Vista, so someone who read this post have to make codes for 64bit version.. Sorry, It is out of my ability. hahaha....

Bye, guys...
