_ispressed problem when using a letter in the hexkey

[computergroove]

https://www.autoitscript.com/autoit3/docs/libfunctions/_IsPressed.htm

If I try to run a script with the following I get an error:

If _IsPressed(6F) Then;hex key for "/"
        msgbox(0,"","/")
    EndIf

It works when I am using a hexkey that doesn't have a letter in the character code. For instance:

If _IsPressed(55) Then;hex key for "u"
        msgbox(0,"","u")
    EndIf

This works. Can I use the ascii dec character code instead of the hex code?

"6F", not 6F

You could also use the $VK_* constants in the WinAPIvkeysConstants.au3 file if you want to keep track of what keys you're looking for. This way, 6 months down the road, you won't have to open the help file just to remember what "6F" stands for.

Would that be:

#include <WinAPIvkeysConstants.au3>
#include <MsgBoxConstants.au3>

While 1
    Sleep(100)
WEND

If _IsPressed($VK_*u) Then
    msgbox(0,"","u")
EndIf

 

[jdelaney]

No, an asterisk symbolizes that there are multiple defined variables with the prefix of $vk_...go find them.

Not sure about your version, but mine are all defined in apiconstants.au3.

Seriously? You're going to post that? Did you even LOOK in the file WinAPIvkeysConstants.au3?

Instead of asking the question, wouldn't it have been MUCH faster to TEST it? Then you would have known that wasn't what I suggested at all.

Maybe I'm looking at the wrong thing. I opened the WinApivkeysConstants.au3 and I see Global Const $VK_U = 0x55 but is that just for an upper case U? There is no second entry for a lower case u. Is there a page that demonstrates the usage?

[BrewManNH]

No there is no constant for upper/lower case keys, they're all the same. If you want to use shift with the U key, you'll have to use _IsPressed to look for each individually. _IsPressed (and by extension the function GetAsyncKeyState in user32.dll) doesn't care if the caps lock is on or not, it's just looking for the key scancode. So you can't test for upper or lower case letters being pressed.

The usage page you're looking for is called the help file, look under _IsPressed for an example script.
