How in GUI to show the text from the file which changes?

Recommended Posts


In the file 1.txt in the first line there is an inscription, and it changes over time. In the GUI, it should also be changed.How to make it not flicker?

Local $Form1 = GUICreate('Form1', 261, 200, 192, 124)
$10 = FileReadLine ( "1.txt",  1);
Local $spic = $10, $Pic1
While 1
    $Pic1 = GUICtrlCreateLabel($10, 10, 70, 235, 50)
    Switch FileExists($spic)
        Case 0
            If $Pic1 Then
                $Pic1 = 0
        Case 1
            If Not $Pic1 Then $Pic1 = GUICtrlCreateLabel($spic, 16, 24, 212, 124)

Why not use GuiCtrlSetData and/or GuiCtrlSetState?  The flicker is because you keep creating the label over and over again in the loop.

Also if you want the label to resize according to length etc.. see Melba23 excellent StringSize udf.

To prevent flickering, you should also only update the label if the contents change/need to change. This will keep flickering to a minimum by only changing it when needed, not every time through the loop.

If I posted any code, assume that code was written using the latest release version unless stated otherwise. Also, if it doesn't work on XP I can't help with that because I don't have access to XP, and I'm not going to.

I hereby grant any person the right to use any code I post, that I am the original author of, on the autoitscript.com forums, unless I've specifically stated otherwise in the code or the thread post. If you do use my code all I ask, as a courtesy, is to make note of where you got it from.

      I have a python script automate.py and I wanna run it via CMD.
      As I know to execute python via CMD is something like this
      $CMD = "Something python here" Run(@ComSpec & " /c " & $CMD) But how can I just open the 1 CMD and send multiple commands to the CMD based on the function called?
      For instance like:

      Launch CMD and send python then send import automate If google() function is called - send automate.google() to the CMD If yahoo() function is called - send automate.yahoo() to the CMD  I don't want to execute multiple CMD to call the automate functions. This is due to inside the python script have global variable to handle duplicate flag.
      So if I execute multiple CMD to call the functions, the global variable will be keep new as NULL. Which is not my expectation.

      I only found that AutoIt can actually execute the entire python script or execute the .exe (converted to .exe from .py)
      But what if I just want call the particular function? If that possible to do so?
      This is because python can't create fancy GUI like AutoIT does. So my plan is use AutoIT to have fancy GUI.
      Then each buttons will trigger specific function in the python script or .exe file.
      For instances:
      btnSum - trigger function in python script or .exe file (funcSum)
      btnMinus - trigger function in python script or .exe file (funcMinus)
      Thanks for advance information.

      _Metro_SplashTextScreen(1, "", $iMsg) AdlibRegister("_Metro_LoopInProgress") DirRemove($DIR_WA_FOLDER, 1) Local $iCopy = _WinAPI_ShellFileOperation($CUR_WA_FOLDER, $DIR_WA_FOLDER, $FO_COPY, BitOr($FOF_SIMPLEPROGRESS, $FOF_NOCONFIRMMKDIR)) AdlibUnRegister("_Metro_LoopInProgress") _Metro_SplashTextScree If @error Then _Metro_MsgBox(0, "", $iCopy) _FileWriteLog($LOG_INSTALLATION, "Error: " & $iCopy) Else _Metro_MsgBox(0, "", "Application is up to date!") _FileWriteLog($LOG_INSTALLATION, "Debug: Application is up to date.") EndIf According to the help file of _WinAPI_ShellFileOperation there are a lot of failure and error code. But how can I handle all of them and display corresponding error message based on the help file?
      The incident is like this:
      I'll lock the folder with permission, so when I execute the _WinAPI_ShellFileOperation to copy and overwrite the folder contents, it popped me an error message saying that permission issue to caused I can't access the folder and overwrite the contents.

      Then I clicked Cancel button, and my AutoIT application exit immediately and it's not execute the function _Metro_MsgBox(0, "", $iCopy) to display the message.
      Anyway, I did also tried the code below, the it still display "Application is up to date!"
      According to the help file, 120 - Security settings denied access to the source.
      If @error = 120 Then _Metro_MsgBox(0, "", $iCopy) _FileWriteLog($LOG_INSTALLATION, "Error: " & $iCopy) Else _Metro_MsgBox(0, "", "Application is up to date!") _FileWriteLog($LOG_INSTALLATION, "Debug: Application is up to date.") EndIf

      I have a application that have a function is to create a shortcut to desktop, lets say is ChromePortable.lnk.
      $iCreate = FileCreateShortcut($DIR_WA_FOLDER & '\GoogleChromePortable.exe', $DIR_SHORTCUT, $DIR_WA_FOLDER, '--kiosk "https://example.com/"') So the shortcut will be launch as kiosk mode and force to enter the specific website. However, the user is still able to right-click on the shortcut and modify the target value to remove the kiosk mode. What can I do to disable the user to editing the target value?
      So far, I had asked and tried from SuperUser for advises Disable Shortcut Target Field
      icacls "ChromePortable.lnk" /GRANT EVERYONE:RX So this will set the permission of this shortcut file to only Read & Execute only! But after I set it, the user is still can modify.
      Please kindly advise.
      Please note and assume that user don't have Administration account or etc, that should be only have 1 account to logon to the computer.
      I must disable inheritance to remove all others permissions like SYSTEM, ADMINISTRATORS, etc. Then only GRANT everyone for READ & EXECUTE only.
      But still the user can go to edit the permissions tho. Any advise?
