_IsPressed and HotKeySet

[Baritonomarchetto]

Hi,

toying with "button pressing" I run into the different handling of inputs of this 2 functions: "IsPressed" rely on Hex values, "HotKeySet", instead, on "actual" keys (with some known ecception). This makes, i.e., difficult to set a variable in a .ini file and use it with both the functions.

Is there a solution to this?

Thanks

Would _HexToString help?

[Baritonomarchetto]

Surely helps, thanks

but what about the use of lowercase letters? Why capital letters are used (in hex format) in _IsPressed and not lowercase? Just asking because with "Send" and "HotKeySet" is better to use lowercase ...

EDIT: Hmm, I had no success trying to use both _IsPressed and HotKeySet with the same variable, even converting string to hex (_StringToHex). Any solution to this?

Thanks

If you post an example script, we could be more helpful. I don't know exactly what your problem is.

[Baritonomarchetto]

Let me explain: the function "IsPressed" accepts only a little (predefinite?) group of hex values. You can notice that letters are uppercase. While dealing with Send or HotKeyset, instead, it's generally good rule to use lower case letters. Than, if i define a variable and its hex

Local $var = i ;just an example: "i" could be a value loaded from an ini file
Local $hexvar = _StringToHex($var)

it's not handled correctly by IsPressed because it's not recognized

HotKeySet("$var", "myfunction")
...
...
myfunction()
...
If _IsPressed($hexvar, $hDLL) Then
...
...

Tell me if i was not clear (veeery probable )

Baritonomarchetto,

Why are you using HotKeySet and _IsPressed on the same key in the same script? Why not just use one or the other?

If caps/uppercase is the problem, you can use StringLower or StringUpper to give a consistent upper or lowercase value.

_IsPressed will only accept the hex value of the uppercase letter, in other words, if your ini file has "i" in it, use StringUpper("i") to make it uppercase. Also, do not put the variable $var in quotes inside the hotkeyset, because it's not going to work that way.

Baritonomarchetto,

I wrote a little script that uses _IsPressed, but i am not able to avoid that the key that trigger the script is sent. With HotKeySet the "key" is completely "hidden"... not sent

Baritonomarchetto,

Could you let us see an example of this "little script", because I am having trouble understanding what you mean. From your explanation above it sounds as if using only one of the two (HotKeySet) is exactly what you need. So why the two together?

Thanks: i wrote those strings by heart, so it's very likely that contain errors

Could it be a solution to write something like:

Local $var = i 
Local $hexvar = _StringToHex(StringUpper($var))

Will the pressure of lowercase "i" on the keyboard ("captured" by HotKeySet) be seen by also by _IsPressed when uppercased?

[Baritonomarchetto]

Sure: i will show you something tomorrow (i have it in another PC and diggin it up to my mind is difficult for a newbie like me )

Ok, here we are: take a look at this (reduced) script please

#include <Misc.au3>

Local $hDLL = DllOpen("user32.dll")

Local $keypressed = IniRead(".prog.ini", "key_assign", "key", 41) ;"A" in hex format
Local $otherkey = IniRead(".prog.ini", "otherkey_assign", "otherkey", "i") ; "i" in dec format

While 1
If WinActive("[CLASS:XLMAIN]") Then
bpress()
EndIf
Sleep(50)
WEnd

func bpress()
If _IsPressed($keypressed, $hDLL) Then
Send($otherkey)
While _IsPressed($keypressed, $hDLL)
         Sleep(5)
WEnd
EndIf
EndFunc

DllClose($hDLL)

This allows you to send a "i" when "a" key is pressed. The problem is that also "a" is sent then you will write "ai". Notice also on the iniread that the format of the button pressed is hex ("_IsPressed" function deals with this) and the format of the "other key" is dec (to deal with send function).

To obtain a sort of uniformation of formats for the key pressed and the other key sent, i thought to start dealing with HotKeySet. This solves the problem of the "ai" sending instaed of only "i" and uses dec format for keys BUT doesn't allow you to use i.e. parts like

While _IsPressed($keypressed, $hDLL)
         Sleep(5)
WEnd

wich is usefull if you wanna stop a ciclying.

Writing something like:

While HotKeySet($keypresed)
         Sleep(5)
WEnd

doesn't stop the key being sent if the button is kept pressed

This is essentially why i want to use both the functions ...

So the questions are:

1) how can modify the script to avoid the send of the key (i.e. "a") that pressed triggers the "otherkey" (i.e. "i")?

2) Couldn't the formats be uniformed (dec hex) with some trick or, eventually, lower case letters be introduced in _IsPressed ?

Thanks for the support
