How to make the computer think that a key has been pressed?

2007-02-15T13:44:25-05:00

You can OUT a key value using &H60 on 98 and older machines. XP will not allow changes to settings in the BIOS keyboard including lites.

Try the following to get the key press and release codes.

Do: press$ = INKEY$
code = INP(&H60)
locate 20, 20: PRINT press$; code
LOOP UNTIL press$ = CHR$(27)

The release code is 128 more than the press code. Numbers Lock may mess up the shift and arrow key codes returned however. If both shift keys = 170 then change the numbers lock mode. I have a list of many DOS BIOS routines. Just email me with DOS BIOS in message!

Well, as I wouldn't use this as a keylogger or whatever, I am still curious as to what you would have to do. I want to make a "virtual keyboard" program for my TUI.

Hey Patz, not sure if I can be of any help but pm me about this. We'll see what's possible!

Yes but when you have big brothers that do not like you on the computer it?s really fun to see them try and figure-out why the screen saver is not on.
But now I made a program that keeps a user off a program without a password.

Oh really???

What about your keylogger post?

You know... You can set the screen saver to NONE.....

Sorry, that should have been directed towards Evan. Although I think we all know his true intentions...

What might help is if you state your true intentions rather than dancing around the mulberry bush, know what I mean?

I'm not actually going to try this, if that's what you mean. I'm busy with my own projects as well as school. I was just suggesting a method that might work.

Is it possible to use Windows API calls in QB?

No, it's not.

I'm thinking that maybe writing something in C that can be called with SHELL or piped through the QB program might work for that.

You would need to use the GetAsyncKeyState API call, it picks up keystates whether the parent application has focus or not. But I don't think that that's what he's looking for...it looks more like what he wants is a program that enters keystrokes by itself, in which case, SendKeys will do the job.

Maybe I'm wrong, but I don't think the keys would register if the program was running in the background, even if it's reading them directly from the keyboard port, at least in WinXP or something. It might work in a dos based os like Win95, but I'm still not sure.

Maybe QB isn't the right tool for the job.

How can you make the computer think that a key has been pressed?
You can do this in QB by using INKEY$ or ON KEY.

But you should expalin in more detail what you need or want to do.

He made a post about a keylogger before... So I'm guessing he wants to make a program that gets a key (before the OS does), record it, and then pass it to the OS. That way, you have a "keylogger". Records every key pressed, without the knowledge of a more advanced user.

Is that right...?

That shneakyshneaky Evan.

I was wondering the same thing: I've been developing a virtual keyboard program, and was wondering how to do this in QB. What ABSOLUTE calls would you have to make?
