I am using delphi (but could be done in any other langage) to develop a simple keylogger using GetAsyncKeyState
I can capture the key code, but this is not related to my local keyboard mapping
ex: when I press the "2" key (which on a french keyboard should write the "é", it shows me "2" (VK_2)
My quetsion is : how do I map the GetAsyncKeyState keypressed to the local keyboard ?
You can use MapVirtualKey function with MAPVK_VK_TO_CHAR flag:

Check function MapVirtualKeyEx also, it has locale identifier as input.

The "delete" key on my Macbook is broken. I am attempting to use the hidutil command to remap F1 as my new delete key. The command isn't performing as expected.
The command requires the hex ID's for the keys whose values I'd like to interchange. I've located a resource that provides these hex ID's as well as an overview of how to perform the remapping (https://developer.apple.com/library/archive/technotes/tn2450/_index.html).
I've posted my specific code below. It adheres to the suggested format, but my OS doesn't seem to register any change. Can someone help me identify the issue? I suspect my Hex ID's are wrong, but it may very well be another issue.
Input :
hidutil property --set '{"UserKeyMapping":[{"HIDKeyboardModifierMappingSrc":0x2a,"HIDKeyboardModifierMappingDst":0x3a}, {"HIDKeyboardModifierMappingSrc":0x3a,"HIDKeyboardModifierMappingDst":0x2a}]}'
Output :
UserKeyMapping:(
{
HIDKeyboardModifierMappingDst = 58;
HIDKeyboardModifierMappingSrc = 42;
},
{
HIDKeyboardModifierMappingDst = 42;
HIDKeyboardModifierMappingSrc = 58;
})
There are no error objects. And judging by the output after the command is run some key remapping has occurred. However, my F1 key still retains functionality as F1 and doesn't delete I'd expected.
Your referenced link on apple.com says "The keys take a hexadecimal value that consists of 0x700000000 or’d with the desired keyboard usage value." So I think you should try e. g. HIDKeyboardModifierMappingSrc":0x70000002a ...
Thanks for the above information, I was able to remap the right Ctrl key to be the Command key on the mac with the following command.
% hidutil property --set '{"UserKeyMapping":[{"HIDKeyboardModifierMappingSrc":0x7000000e4,"HIDKeyboardModifierMappingDst":0x7000000e3}]}'
This is because I am using a very old IBM original keyboard that does not have a windows key, just an empty space between the Ctrl and Alt keys on the left and right of the Space bar.
I'm currently sshing from my mac to a CentOS box, where I run emacs. For whatever reason, the shift key doesn't seem to work when issuing a keyboard sequence. I suspect the wrong key code is being sent.
For example, I've remapped my help command to the following:
(global-set-key (kbd "C-?") 'help-command)
Executing this keyboard sequence in a typescript file reveals that it's invoking the delete-backward-char command, which is a compiled Lisp function from simple.el. (In order to even check what command the keyboard sequence was executing, I had to temporarily remap help to C-o.)
Similarly, I have the following key binding set up for typescript mode
(setq tss-popup-help-key "C-:")
Likewise, it looks like the SHIFT key hasn't registered because I get the following definition in the help manual when I reverse lookup the sequence:
; runs the command typescript-insert-and-indent, which is an
interactive compiled Lisp function in `typescript.el'.
It is bound to ,, ;, ), (, }, {.
(typescript-insert-and-indent KEY)
In other words, emacs registers the colon as a semi-colon.
This is a recurring problem with keyboard sequences that require me to use a SHIFT key. How do I get the SHIFT key to work properly when working on emacs through a mac?
For the record, when I use Emacs for OSX, the shift key works great.
Can you remap the CapsLock key in Keymando?
CapsLock is listed as an available key but when I try a test like:
map "<CapsLock-j>" { alert("CapsLock-j") }
... and hit Reload Config in the Keymando menu, I get an error dialog that says:
Error Parsing Keymando Config File
undefined method `ctrl' for nil:NilClass
Is there perhaps an abbreviation of CapsLock? For example, in the available keys, the Control key is just listed as Control but in the example code it is ctrl. Is there a similar abbreviation for CapsLock?
If possible, I would like to use the CapsLock key as a mode key to implement logic like:
if <CapsLock>
map <j>, <Down>
map <k>, <Up>
# ...etc
end
Sorry, that's a mistake on our part listing Capslock on the website. Currently it can only be remapped to Control, Option, or Command via the Keyboard.prefPane under "Modifer Keys.." and there's no way for us right now to detect if it's been pressed.
We'll keep our eyes open for a solution but as of right now it's not going to do what you're wanting. Sorry.
The website has been fixed to avoid any more confusion, as well.
While you can't remap capslock, you can achieve almost the same functionality by adding some basic state to your keymandorc file. I couldn't figure out how to map something to the option key alone, but apart from that, this should do what you are aiming for:
At the top of your keymandorc put:
#caps = false
Then down wherever you define your bindings put something like the following
map "j" do
if #caps then
send("<Down>")
else
send("j")
end
end
map "<Option-v>" do
#caps = !#caps;
alert("Vim Mode: " + #caps.to_s)
end
You could then also bind escape to exit the mode if #caps is true, and so forth.
I tried to use the virtual key code provided by wParam, however that didn't work very well:
multiple keys mapped to the same key code
some keys were not recognized at all
virtual keys seemed to be adapted to the keyboard layout (which i don't want/need)
Then i saw that the lParam will give me a scancode along with an "extended" flag, which seem to produce a different value for every single key on the keyboard when calculated like this:
value = (lParam & 0x01FF0000) >> 16;
Will this value always be identical for the same key on the keyboard, even across various keyboards/systems?
Scancodes can be different for different keyboards. Best to use virtual key codes. From http://msdn.microsoft.com/en-us/library/ms646267(v=vs.85).aspx:
Assigned to each key on a keyboard is a unique value called a scan
code, a device-dependent identifier for the key on the keyboard. A
keyboard generates two scan codes when the user types a key—one when
the user presses the key and another when the user releases the key.
The keyboard device driver interprets a scan code and translates
(maps) it to a virtual-key code, a device-independent value defined by
the system that identifies the purpose of a key.
How do I programmatically trigger Flip 3D on Windows Vista and 7?
Is there an API for this and if so, what is it called and where can I find the relevant functions? (I need a specific answer, eg a web link to the actual functions, not something generic like "Oh, it's in DirectX.")
On a related node, I have a Logitech mouse that has a "Document Flip" button that invokes Flip 3D (and then I can press up/down keys to page through the results.) I am curious if they are using an official Windows API or if there is some low level hackery going on.
you need to run a function from dwmapi
Sadly there is no proper funktion name only the ord-number 105
You can try this by executing %WinDir%\System32\rundll32.exe dwmapi #105 from Run-dialog or cmd.
edit
ive found out the Windows' API GetProcAddress Function accepts ord-numbers (the 105) as second parameter as well as proper name
lpProcName [in]
The function or variable name, or the function's ordinal value. If this parameter is an ordinal value, it must be in the low-order word; the high-order word must be zero.
so use this code
typedef vois (__cdecl *FlipProc)();
HINSTANCE hDwmApi = LoadLibrary(TEXT("dwmapi.dll"));
FlipProcAdd = (FlipProc) GetProcAddress(hDwmApi, (LPCSTR)105);
(FlipProcAdd)();
