Read all assigned keys from Keyboard

Recommended Posts

Hi All,

I've bought a Ergodox EZ programmable keyboard with layers of key maps (eg, layer 0 = dvorak, layer 1 = numberpad & nav, layer 2 = qwerty, etc), I've also got a small USB screen that can pull information from the registry. What I would like to determine is a way to pull the value of each current key from the keyboard, I can then write the values to the registry and pull them into my USB screen so I can see the keyboard key layout.

I'm stuck with retrieving the key values, I've looked at _IsPressed(), _WinAPI_GetKeyState(), _WinAPI_GetKeyboardState(), _WinAPI_GetKeyboardType(), _WinAPI_GetKeyNameText(), but none of them appear to be able to pull the keyboard key values without user interaction.

The idea being, in pseudo code, bear in mind no error checking etc in this code, "GetKeyValue()" is what I'm needing help with and is a made up function, as is "HardwareKey1" etc:

$keyOnePrev = ""
$numOfKeys = 76
While 1
   $keyOneCurrent = GetKeyValue(HardwareKey1)
   If $keyOneCurrent <> $keyOnePrev Then
      For $key = 1 To $numOfKeys
         $keyToWrite = GetKeyValue(HardwareKey & $key)
         RegWrite("HKEY_CURRENT_USER\Software\myKeyboard", "key" & $key, "REG_SZ", $keyToWrite)
      Next
   EndIf
   $keyOnePrev = $keyOneCurrent
   Sleep(5000)
WEnd

Thanks guys!

typos, update $keyOneCurrent script location

what is wrong with the built in registry functions? also, while you are at it, pseudo code the GetValue function too.

My resources are limited. You must ask the right questions

      Hi AutoIt Programmers!, I just looking for a way to change entered keys in English to Russian keys and reverse, i must clear for you to understand. For example:
       
      I write keys on keyboard and i forgot to change input language and then the result will be: Dkflbvbh (Thing we write in fact) ====> Владимир (Thing we want)
       
      And reverse: Владимир  ====> Dkflbvbh

      Is there any solution without writing constant for each words? for example dlls or WinAPIs.

      Greetings,
       
      Someone can help-me to translate this Python's code to AutoIt?
       
      Python (source: https://repl.it/repls/InstructiveDarkslategreyJackrabbit)
      str = 'age=12,name=bob,hobbies="games,reading",phrase="I\'m cool!"' key = "" val = "" dict = {} parse_string = False parse_key = True # parse_val = False for c in str: print(c) if c == '"' and not parse_string: parse_string = True continue elif c == '"' and parse_string: parse_string = False continue if parse_string: val += c continue if c == ',': # terminate entry dict[key] = val #add to dict key = "" val = "" parse_key = True continue elif c == '=' and parse_key: parse_key = False elif parse_key: key += c else: val+=c dict[key] = val print(dict.items()) Python's output:
      [('phrase', "I'm cool!"), ('age', '12'), ('name', 'bob'), ('hobbies', 'games,reading')] AutoIt
      #include-once #include <Array.au3> #include <StringConstants.au3> Global $opt $opt = "estado = """" , cep = """", idade=32, nome = ""Luismar"", campo=""campo = campo""" $opt = "age=12,name=bob,hobbies=""games,reading"",phrase=""I\'m cool!""" ConsoleWrite($opt & @LF) Local $arr = StringSplit($opt, "", $STR_CHRSPLIT) Local $key = "" Local $val = "" Local $dict = ObjCreate("Scripting.Dictionary") Local $parse_string = False Local $parse_key = True Local $c For $ii = 1 To $arr[0] $c = $arr[$ii] If $c == '"' And Not $parse_string Then $parse_string = True ContinueLoop ElseIf $c == """" And $parse_string Then $parse_string = False ContinueLoop EndIf If $parse_string Then $val &= $c ContinueLoop EndIf If $c = "," Then $dict.Add($key, $val) $key = "" $val = "" $parse_key = True ContinueLoop ElseIf $c == "=" And $parse_key Then $parse_key = False ElseIf $parse_key Then $key &= $c Else $val &= $c EndIf Next $dict.Add($key, $val) ; missing this line... For $each In $dict ConsoleWrite($each & " = " & $dict.Item($each) & @LF) Next AutoIt's output
      age=12,name=bob,hobbies="games,reading",phrase="I\'m cool!" age = 12 name = bob hobbies = games,reading  
      Best regards.

      Hello,
      i searched the forum for something near, but with no success...
      I have Combobox control with $CBS_DROPDOWNLIST style with some items (for example (one, two, nine).
      When i want to select the item, using keyboard, the items are selected only on First letter base (for example when i type "on", Nine is selected).
      Is there some trick to force the combobox with $CBS_DROPDOWNLIST style to accept more than the First letter during selecting the items from the list?
      Mi wanted result is the same as for example - when you type "fir" on the desktop, Firefox is automatically selected.
      Thank you so much.

      I have a situation where the desktop is designed in java swings. The nodes JTree is not allowing me to do checkbox selection using "spacebar". I am able to navigate through the nodes using up, down arrow and a tab. When I reach to the desire node selection, mouse left click is not working due a flaw a JTree core. However since it is selected, if mouse cursor auto moved to the position of the selection and send a "click"  then it should be solved. Any ideas much appreciated. 
      the problem with having fixed coordinates are the main windows is divided to 2panels where right panel containing this JTree can be expanded or shrink-ed.
