Change Label if key Is Pressed

Recommended Posts

Hi guys,

I'm learning about GUI's, I'm trying the below code, the idea being if I press the letter "e" while I have the GUI open I want the label color to change to green (I'm using a UDF for label colors). But every time I press "e" on my keyboard I just get a "ding" sound from my speakers and nothing changes with the label.

I've looked at using something like "While GUIGetMsg() <> $GUI_EVENT_CLOSE" as I've seen it in other code instead of "While 1", but I don't think it's relevant.

#include <GUIConstantsEx.au3>; for GUI...
#include <GUIRichLabel.au3>; UDF for rich text label fonts
#include <Misc.au3>; for _IsPressed

$myLetter = "e"

$hGUI = GUICreate("test", 700, 60)

$lbl2 = _GUICtrlRichLabel_Create($hGUI, '<font color="purple">' & $myLetter & '</font>', 10, 10); , 260, 25

GUISetState(@SW_SHOW)


Local $hDLL = DllOpen("user32.dll")
While 1
   if _IsPressed(Hex($myLetter), $hDLL) Then
      While _IsPressed(Hex($myLetter), $hDLL)
         Sleep(250)
      WEnd
      _GUICtrlRichLabel_SetData($lbl2, '<font color="green">' & $myLetter & '</font>')
      Sleep(2000)
      DllClose($hDLL)
      Exit
   EndIf
   Sleep(50)
WEnd
DllClose($hDLL)

I am using an array of letters that I'm wanting to do this for, but as I can't get it to work I've stripped it down to the simplest code I can think of to try and get this working first. Appreciate any help.

Thanks!

I think that this is caused by the GUI that hasn't the focus, and so, that sound indicates an invalid action of the current focussed GUI.

I think that you have to see when you are in your GUI, using WinGetState() to see if you are able to interact with your GUI, and, if it is not, you could use the other Win* functions to make it possible.

Try that and let us know :)

I saw this code which looks interesting

#include <GuiConstants.au3>
#include <windowsconstants.au3>

GUICreate("MyGUI")

GUISetState()
GUIRegisterMsg(0x101,"WM_KEYDOWN")


While 1
    $msg = GUIGetMsg()
    Select
        Case $msg = $GUI_EVENT_CLOSE
            ExitLoop
    EndSelect
WEnd
Func WM_KEYDOWN($hWnd, $msg, $wParam, $lParam)
    ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $wParam = ' & $wParam & @crlf & '>Error code: ' & @error & @crlf) ;### Debug Console
EndFunc

WoodGrain,

The "letter" parameter required for _IsPressed is not Hex("E") but Hex(Asc("E")) - as explained in the Help file. Once you set that parameter correctly, the label colour changes (at least with native labels):

#include <GUIConstantsEx.au3>; for GUI...
#include <Misc.au3>; for _IsPressed

$myLetter = "E" ; This is the letter
$iCode = Hex(Asc($myLetter), 2) ; and this is the code required for _IsPressed

$hGUI = GUICreate("test", 700, 60)
$cLabel = GUICtrlCreateLabel($myLetter, 10, 10, 200, 20)
GUISetState(@SW_SHOW)

Local $hDLL = DllOpen("user32.dll")
While 1
   if _IsPressed($iCode, $hDLL) Then
      While _IsPressed($iCode, $hDLL)
         Sleep(250)
      WEnd
      GUICtrlSetBkColor($cLabel, 0x00FF00)
      Sleep(2000)
      DllClose($hDLL)
      Exit
   EndIf
   Sleep(50)
WEnd
DllClose($hDLL)

Thanks M23, your script works for me too. Would you be so kind to explain to me how you derived the ASC() requirement from the help file? Please be sure I'm not trying to question your comment so much as understand it for myself so I can better understand the doco before posting here next time. I can see the reference to HEX() in that it mentions the 1st parameter as "$sHexKey". Is it just that you already happen to know that those number codes in the list correlate to their ASCII numbers (assuming that's what they are)?

Wow, I also noted in the help file, now that I've tried both lower and upper case letters after noting in your script you used an upper case E, that, as listed in the help file, only upper case letters will work in this scenario! So, after changing my "e" to "E" and adding in the Asc() inside the 2 _IsPressed functions my script worked!

Only remaining question is how do I stop it from making the "ding" noise when I press a key in the GUI lol? That's going to otherwise drive me spare!

Thanks!

A cute workaround (and more selective/secure IMHO) could be to use GUISetAccelerators and a hidden button  :)
Of course it works only if the gui is active...

#include <GUIConstantsEx.au3>

$hGUI = GUICreate("test", 700, 60)
$cLabel = GUICtrlCreateLabel("test", 10, 10, 200, 20)
$fake = GUICtrlCreateButton("", -10, 0, 1, 1)
Local $aAccelKeys[1][2] = [["e", $fake]]
GUISetAccelerators($aAccelKeys)
GUISetState(@SW_SHOW)
Local $n

While 1
      Switch GUIGetMsg()
            Case $GUI_EVENT_CLOSE
                Exit
            Case $fake
                $n = not $n
                GUICtrlSetBkColor($cLabel, ($n? 0x00FF00 : 0xFF0000))
     EndSwitch
WEnd

Thanks Mikell! I can confirm that if I press the correct key ("e" in this example) it doesn't make any sound and does change the color (in fact toggles the color?), however if I press any other key on my keyboard it still makes that awful ding sound. I'll have to spend some time looking at how to get this to work with my array of letters too. Thanks.

Exactly that - knowing how the function works internally helps too.

All good M23, I'm aware of that, I'm writing myself a touch-typing app so I can do dvorak training.

I'm using Klavaro atm to learn dvorak, but it has to be up in the middle of my screen, and I have to type 400+ characters per lesson, I'm writing an app that will just pop-up and hide on hotkey, pull in the current lesson from my lesson plans, and as I type if I press the right key for the letter it will change the color to green, then at the end of the text will load the next random letters from the lesson. "Dinging" every time I make a typo will certainly annoy the staff around me in no time lol.

<offtopic>tbh I've been doing some c++ training on the side and would love to learn to start doing this sort of stuff in c++ instead of AutoIT, but haven't got past console basics with if/loops/etc, wouldn't know where to start with a GUI in c++, from what I can see you need to use 3rd party tools to do this.. so here I am writing it in AutoIT lol.</offtopic>

For C++ GUI Editor, I'd suggest Borland C++ Builder, which is a very complete and powerful tool to build your GUIs, and much more.

But, if you wanna make it easy, why don't you use Koda Form Designer, which comes with AutoIt, and it's a complete and powerful tool too ( which generates .au3 code too )? ;)

Anyone have any thoughts as to how I can stop the noise in my GUI?

Do I need to use an Input Box and have the program read the last letter on input and use that?
Wouldn't look as clean though.

So, after thinking this through it looks like the best method will be to add in an Input Control that I can type into and then use GUIGetMsg to poll it for any changes and then from that run my function to check if the last char they typed in the control is correct compared to the current letter from my array, I've read about $SS_NOTIFY with the control to assist with this.

You can use a WM_COMMAND too :)

#include <Date.au3>

GUICtrlSetFont(-1, 10, 400)
GUISetState(@SW_SHOW, $frmMainForm)
#EndRegion ### END Koda GUI section ###

GUIRegisterMsg($WM_COMMAND, "WM_COMMAND")

    Sleep(100)

    Exit

    $intMessageCode = BitShift($wParam, 16)

    Switch $intControlID_From
        Case $txtInput
            Switch $intMessageCode
                Case $EN_CHANGE
                    ConsoleWrite("[" & _Now() & "] - The text in the $txtInput control has changed! Text = " & GUICtrlRead($txtInput) & @CRLF)
            EndSwitch
    EndSwitch

      Hi guys
      what i am trying to do is have My Gui LIve update Out of focus, so i can have this on a 2nd monitor streaming live updates while i continue to work on other screen, 
      i have been googling and looking at other threads about focus and stuff , but they do not seem to match what I'm after, 

      to be clear - i am not wanting to put focus on the GUI for it to auto update values, 
       
      if you have any positive feed back on the script while you read - i would be more then happy to accept - as im still building my Knowledge of this coding, 
      and stream line is always better Garbage code writing, 
       
      Kind regards 
      Gngnut

      Hi all,
      I've been looking around the forum and testing different ways of getting a 'drop zone' to work in my script, but I can't seem to get any response from the event listener. Code compiles perfectly. Chaning the control from a label to an input- or edit-field doesn't change its behaviour, still no response when a file is dropped on there...
      It might just be that I am overlooking a simple detail, so I'm hoping for an extra pair of eyes here or there who can spot why this isn't working as it should. 
      I have another 3500+ lines script where I have basically the same bit of code, and it seems to work in there without problems.
      So, here it goes:
      Global $DD_GUI = GUICreate("DicomDrop",200,200,-1,-1,BitOR($WS_SYSMENU,$WS_POPUP),$WS_EX_ACCEPTFILES) GUISetBkColor(0x030303,$DD_GUI) $DD_GUI_DRAGLABEL = GUICtrlCreateLabel("",0,0,32,32,-1, $GUI_WS_EX_PARENTDRAG) $DD_GUI_DRAGIMAGE = GUICtrlCreateIcon(@ScriptFullPath,201,0,0,32,32) $DD_GUI_TITLELABEL = GUICtrlCreateLabel("DicomDrop",50,10,100,20,$SS_CENTER) GUICtrlSetFont($DD_GUI_TITLELABEL,8,$FW_SEMIBOLD,$GUI_FONTNORMAL,"Verdana") GUICtrlSetColor($DD_GUI_TITLELABEL,0xFFFFFF) $DD_GUI_CLOSE = GUICtrlCreateButton("X",174,4,24,24,$BS_FLAT) GUICtrlSetBkColor($DD_GUI_CLOSE,0x030303) GUICtrlSetColor($DD_GUI_CLOSE,0xFFFFFF) Global $DD_GUI_DROPZONE = GUICtrlCreateLabel("",10,42,180,148) GUICtrlSetState(-1,8) GUICtrlSetBkColor($DD_GUI_DROPZONE,0x181818) GUISetState(@SW_SHOW,$DD_GUI) Local $DD_MSG = 0 While 1 $DD_MSG = GUIGetMsg() Select Case $DD_MSG = $GUI_EVENT_CLOSE ConsoleWrite(@CRLF & "Debug -- Closed by GUI_EVENT_CLOSE") DD_EXIT() Case $DD_MSG = $GUI_EVENT_DROPPED If @GUI_DropId = $DD_GUI_DROPZONE Then Local $DroppedFile = @GUI_DragFile GUIDelete() ConsoleWrite(@CRLF & "Debug -- Dropped file : " & $DroppedFile) EndIf Case $DD_MSG = $DD_GUI_CLOSE ConsoleWrite(@CRLF & "Debug -- Closed by DD_GUI_CLOSEIMAGE") DD_EXIT() EndSelect WEnd Func DD_EXIT() GUIDelete($DD_GUI) Exit EndFunc If anyone has any idea whatsoever, please let me know 🙂
      Thanks in advance and kind regards,

      Hi AutoIters!
      Here is my new UDF about GUIs: it's an enhanced mixture of Advanced InputBox (deprecated) and KODA Parser (deprecated), with additional functions.
      What you can do with it:
      Parse KODA files and directly create GUIs (_GUIUtils_CreateFromKODA) Parse a simple JSON form definition to simply create advanced InputBoxes with any amount/type of input controls (_GUIUtils_CreateFromJSON) Created GUIs are returned as Scripting.Dictionary objects, and you have helper functions to access GUIs controls by their names (_GUIUtils_HWnd, _GUIUtils_CtrlID, _GUIUtils_HCtrl ...) A function that can make a GUI created from KODA/JSON (defined by it's $oForm object) and make it a modal InputDialogBox (just like InputBox, but returns all entered data as Scripting.Dictionary object) Functions are documented, and there are some examples.
      Consider this UDF as beta, but since I'm currently using it in a small commercial project, it should become production ready in near future.
      To always get the latest code version, get it from Github (more up to date than this topic).
      Update 04/02/2020:
      New simple application example Fixed focused control handling in _GUIUtils_InputDialog Reset input values before returning from _GUIUtils_InputDialog Fixed CloseOnEsc in _GUIUtils_InputDialog Fixed Input not reset Fixed all ListBox items are selected Project now on GitHub https://github.com/matwachich/autoit-guiutils/
      Update 05/02/2020:
      Support for nodate for Date and Time input controls (pass null value) New handling of focused control _GUIUtils_InputDialog: Now, you can specify the focused control in $oInitialData by setting "controlName:focus" = True Updated documentation of _GUIUtils_InputDialog Update 07/02/2020:
      Bug corrected when setting Data input control Added: abillity to read a single input control New functions (_GUIUtils_GetInputs, _GUIUtils_WriteInputs), documentation completion. Readme file and screenshots on Github Page

      I am not able to use the $GUI_READ_EXTENDED with the  Metro UDF,  any work around ?
      Local $aPos[2] = [$Radio1, $Radio2] For $Radio In $aPos If GUICtrlRead($Radio) = $GUI_UNCHECKED Then ContinueLoop IniWrite($sGUIstate_IniFile, "Data", "POS", GUICtrlRead($Radio, $GUI_READ_EXTENDED)) ;; return the text of the menu item ExitLoop Next

      Hello forum,
      I want to create a program with multiple menus and many elements inside. The problem is my way of doing this and below I have an example of how I do these menus.
      I know it's a bad way of doing them as using this method for more elements and menus cause big flickering.
       
      Can someone please help me with some tips of optimizing this or tell me another way of creating that menus with many elements without cause flickering? From a long time ago I still try to solve this but without any results, just small improvements.
      Many thanks for everyone.
