When I press keys, do a certain job

[DragonBall]

I am trying to do the following:

When I type 0~9 or a~z or A~Z ( in fact more, like space, backspace...) in an editor ( for example : Notepad), then it will send "Ctrl + s " to save the file.

I have found a solution on internet as following:

While 1

sleep(100)

For $i = 32 to 127

if ( _IsPressed(Hex(8)) OR _IsPressed(Hex($i)) ) Then

Send("{F9}")

EndIf

Next

WEnd

But I don't like it, because each time when I type a letter, it will try to test the for loop i = 32 ~ 127. But I don't care which letter I typed, I just need to send "Ctrl + s" each time I type a letter, no matter which one. But I didn't find a way to do this.

It would be much better if it doesn't need to do sleep(100) during the while loop, instead it waits me to press the next key and send "Ctrl+S".

This sounds like a keylogger and is not a subject that the AutoIt forums like to answer.

Please read the rules about posting these types of posts.

Also, I hope this script works only when I type in Notepad. I tried the following script, but it doesn't work:

While WinActive("Untitled - Notepad")

sleep(100)

For $i = 32 to 127

if ( _IsPressed(Hex(8)) OR _IsPressed(Hex($i)) ) Then

Send("^s")

EndIf

Next

WEnd

This is not a keylogger because I don't want to know which key I typed.

Then - why not write to the editor and when finished save it. Why would you want to save the file after each letter/char is entered?

[DragonBall]

Ok, the reason is : I use WinEdt as latex editor, but I like the "continuous preview" feature, see "Bakoma" for what this feature means. So I tried to make WinEdt has this feature. I use sumatraPDF as pdf viewer and set F9 as shortcut for compile by pdflatex.

Finally, I use autoit to send F9 when each letter is entered. Now, everything is very good. I just hope I could make it a little bit fast and fewer cpu resource consummation by improving the above script.

If you want it faster, why dont you remove "sleep(100)" or reduce the time? the number is miliseconds.

[DragonBall]

Sure, but it will use more cpu resource.....

Your script closes by itself, dont you want to keep it running until you close it?

Edit: all you need is your script to simulate ctrl+s in each key you press right? and now it is simulating that when you press F9.

Check this one out, it checks for the notepad process instead of window, because the caption changes depending on the file that is open,

and when you press F9, it saves, meaning it presses Ctrl+S. It stays on tray, until you close it.

See how it works for you

#requireadmin
#Include <WinAPI.au3>

Local $save
$save = 0
HotKeySet ("{F9}", "save")

Func save()
    If ProcessExists ("Notepad.exe") then
    Send("^s")
    _WinAPI_Beep(1500, 100)
    EndIf
EndFunc

Do
sleep(100)
Until $save = 1

EDIT: oh, and the beep thingy is so that you know that the hotkey was pressed, otherwise you might not be sure, anyhow, if you dont want that, just delete it.
