Using HotKeySet

14 posts in this topic

Hello All,

I am trying to use Hotkeyset to detect when a user presses ALT + SHIFT + Backspace + DEL

When this key combination is pressed simultaneously I will call my function. Here is what I have so far:

;This calls my function as soon as ALT + SHIFT + DEL is pressed (doesn't wait for backspace)

HotKeySet("!+{DEL}{BS}", "Escape")

Can anyone tell me what i am doing wrong?

Re-read the HotKeySet page in the help file, specifically those keys that cannot be set.

I read it and I see (it appears to me) no reason why you can't do it. This is what is said on it (from the help file)

Ctrl+Alt+Delete

It is reserved by Windows

F12

It is also reserved by Windows, according to its API.

NumPad's Enter Key

Instead, use {Enter} which captures both Enter keys on the keyboard.

Win+B,D,E,F,L,M,R,U; and Win+Shift+M

These are built-in Windows shortcuts. Note: Win+B and Win+L might only be reserved on Windows XP and above.

Alt, Ctrl, Shift, Win

These are the modifier keys themselves!

Other

Any global hotkeys a user has defined using third-party software, any combos of two or more "base keys" such as '{F1}{F2}', and any keys of the form '{LALT}' or '{ALTDOWN}'.

Oh wait -

Is this the reason? I'm not quite understanding it but I think this is what you are getting at.

Its interesting because I do see that it says you can't do Ctrl, Alt and Shift because they are modifiers, but I figure there is still some way to do it because Alt + Shift + Del works fine. So that part about the keys that you can't do does not seem to be completely accurate.

What it's saying is that you can't map a hotkey directly to just the CTRL/ALT/Shift key, you have to use one of them in combination with another key, such as CTRL-C. Other than that, I don't know what he's referring you to in the help file.


If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I have always taken it, as Yogi pointed out, that two or more base keys would not work - sorry if I was being vague. I know that you can set a hotkey for "!s", for example. But setting it for "!+" would not, or at least has never done so for me. I'm happy to be proven wrong though :) Perhaps it is simply a limit of the number of inputs it will take.

Example, this works fine:

HotKeySet("!s", "test")

While 1
Sleep(1000)
WEnd

Func test()
MsgBox(0, "", "Entered Test")
EndFunc

Whereas this does not:

HotKeySet("{DEL}{BS}", "test")
While 1
Sleep(1000)
WEnd

Func test()
MsgBox(0, "", "Entered Test")
EndFunc

Edit: horrible spelling

Edit2: Realized my non-working example was done wrong, sorry for the confusion.

OK then, How would I do what I said above? Alt + Shift + DEL + Backspace ?

This works for me:(Alt +Shift+DEL)

HotKeySet("!+{DEL}")

But not when you combine "base" keys, those surrounded by {}. Try this out, it should enter the test function as soon as you it Del.

HotKeySet("{DEL}{BS}", "test")
While 1
Sleep(1000)
WEnd

Func test()
MsgBox(0, "", "Entered Test")
EndFunc

Not sure what you are getting at?

That code doesn't have any of the base keys or the modifier keys. From what it says I think the base keys are the F1 - F12.

But yes this code enters the function as soon as you hit DEL.

I want to enter after hitting ALT + SHIFT + DEL + Backspace

Matter of fact the help file uses two modifier keys in the example

HotKeySet("+!d", "ShowMessage") ;Shift-Alt-d

Ok, I think this is partly my fault for a poor explanation, and for that I apologize. The help file states that you cannot use two "base keys" - which would be any key you surround with {}. Any time you use two base keys, AutoIt will ignore the second one completely. For example:

{DEL}{BS} will react as soon as you hit {DEL}

{F1}{F2} will react as soon as you hit {F1}

{BS}{HOME} will react as soon as you hit {BS}

You can do a combination of base keys and normal modifiers, such as:

!{DEL}

+{BS}

^{HOME}

Thus, having {DEL}{BS} in your code is not going to work. Hope this clears things up for you.
