Replace the keys on the keyboard

Hi

Can anyone help. I would like to replace the keys on the PC keyboard. For
example, when I press Q button it displays A on the screen in any programs
(MS Words, Note, Lotus....). And also when I press Ctrl + W button, it
displays G on the screen. I would like to make the keyboards configurable.

Should I write a Windows Service? Any suggestions would really appreciate.

Please help. Thanks.
Regards

Three suggestions for you to look at:

(1) SetWindowsHookE x() with WH_KEYBOARD_LL for a low-level keyboard hook
(this requires an application with a message loop running on the desktop
of the user it affects).

(2) Write a Windows keyboard layout with the MS Keyboard Layout Creator
(http://www.microsoft.com/globaldev/tools/msklc.mspx).

(3) Install a keyboard filter driver into the kernel, and have your
configuration program communicate with it somehow. Check out
http://www.sysinternals.com/Utilities/Ctrl2Cap.html for techniques for
this (source is on the site, DDK needed IIRC). I wouldn't recommend this
method, since it could compromise the stability of the system.

I personally use (1), an application I wrote to simulate the Dvorak
keyboard layout for use with public PCs which don't allow permission to
change the keyboard layout. The catch with (1) is that some of the key
information you get depends on the current keyboard layout.

If you are only building a simple project using a winform. I would suggest
you to use the MenuStrip control with the ShortcutKeys preperty. Somehow
hide the menu if you want.

You can use a global keyboard hook WH_KEYBOARD_LL to monitor for keyboard
input across all applications. When you receive a specific key event in
which you are interested, you can suppress that event, then send your own
keyboard event.

We offer a .NET component FREE for non-commercial use that will handle all
of this for you:

When I was in boy scouts, as part of learning Morse code, I was told that the inventor of the typewriter originally put the letter 'e' under the left middle finger, just below its present position.

This led me to wonder if 't' might have been moved from the home row for the same reason. 'E is dit and T is dash, under middle...

Well, it seems that Microsoft, or whatever powers that be have decided it's time for us to have yet another standard keyboard layout change. I think I see that the point of this one was to reduce the space occupied by the keys on the right, so the reach to the mouse is not so bad, but the way they chose to do it? Ah - I see. Since most of what we type will simply be deleted at some point, let's make sure the Delete key is big and easy...

I've got a very large C# forms app and now that its being used in bigger environments we're getting a steady stream of "why does it do this?" problems.

From searching online, this is apparently by design(for whom, I don't know, why its not optional, I _really_ don't know). This...
