Function Question

Recommended Posts

Maybe I am trying this all wrong, but hope someone can help. I have a GUI and want to click a button which will start a function to get a folder location. Then I need to pass that location to a variable to use outside the function. Here is a sample of the code;It prompts to choose a file location and the message box displays the choice but that is all inside the function. I need to pass the path selected outside the function. OR need a different way of doing this, maybe my approach is wrong.

$Label_Drive=GUICtrlCreateLabel("Use the select button and choose where profiles will be stored.", 15, 120, 240, 25)
$BTN_Set_BKP_Path = GUICtrlCreateButton("Select Location", 250, 120, 90, 30) ;left,top,width,heigth
GUICtrlSetOnEvent($BTN_Set_BKP_Path, "Location")

 

Func Location()
$BKP_Path = FileSelectFolder("Select a folder where profiles will be stored.", "c:\")
MsgBox(0,"Select Path", "You set the path as " & $BKP_Path)
EndFunc

 

$Label_BKP_Path=GUICtrlCreateLabel("Current path is " & $BKP_Path & ".", 15, 150, 300, 25)

Have a look at Return or make $BKP_Path a Global variable (outside the function) then it will retain its value for example:

;Example1
Global $sExample1 = Example1()
    MsgBox(0,"Select Path", "You set the path as " & $sExample1)

Func Example1()
    Local $BKP_Path = FileSelectFolder("Select a folder where profiles will be stored.", "c:\")
    If @error Then Return "Nothing selected"
    Return $BKP_Path
EndFunc

;~ Example2
Global $sExample2
    Example2()
    MsgBox(0,"Select Path", "You set the path as " & $sExample2)

Func Example2()
    $sExample2 = FileSelectFolder("Select a folder where profiles will be stored.", "c:\")
    If @error Then $sExample2 = "Nothing selected"
EndFunc

      Hi guys!, recently i needed to measure two functions and detect fastest one then i decided to write and share this tiny script for compare, measure and detect fastest functions easily.

      It's such as snippets, i hope you find it useful :)❤

      Hi All,

      MAIN QUESTION:
      Is it possible to Call specific function within a GUI

      So I have a script with multiple functions although I don't want to use every function every time.
      My Idea is to create a simple GUI which allows me to select what functions I want to use then run the funtions by clicking a button.
      I have already made a GUI which allows me to select specific .exe's I would like to run after selection it runs the .exe one by one.
      This script is on my work laptops and cannot access it right now.
       
      Who can help me with this?
      GUIcreate
      Func1 
      Func2
      Func3
      Then have a boxes which allows me to select the specif Func.(I used GUIChecked and Unchecked in my other script)
      Then a button which executes/calls the selected functions

      I got a question:  i am trying to run different functions based upon what i select in these radio buttons.(code below)
      it needs to check server 1. then run function 1 or function 2 after what i selected in the checkbox.
      once that function is done it moves to the next one, until it has been trough all 5 
       
      iv'e tried using while loops with different while $i equals to something but then i manualy need to go in and edit the script every time.
      #include <ButtonConstants.au3> #include <GUIConstantsEx.au3> #include <StaticConstants.au3> #include <WindowsConstants.au3> #Region ### START Koda GUI section ### Form= $Form1 = GUICreate("Form1", 615, 437, 192, 124) $Server2 = GUICtrlCreateLabel("Server2", 216, 95, 41, 17) $server1 = GUICtrlCreateLabel("Server1", 216, 72, 41, 17) $server4 = GUICtrlCreateLabel("Server4", 216, 144, 41, 17) $server3 = GUICtrlCreateLabel("Server3", 216, 119, 41, 17) $server5 = GUICtrlCreateLabel("Server5", 216, 170, 41, 17) $Start = GUICtrlCreateButton("Start", 240, 248, 147, 25) $Checkbox1 = GUICtrlCreateCheckbox("function1", 288, 72, 97, 17) $Checkbox2 = GUICtrlCreateCheckbox("function2", 392, 72, 97, 17) $Checkbox3 = GUICtrlCreateCheckbox("function1", 288, 96, 97, 17) $Checkbox4 = GUICtrlCreateCheckbox("function2", 392, 96, 97, 17) $Checkbox5 = GUICtrlCreateCheckbox("function1", 288, 120, 97, 17) $Checkbox6 = GUICtrlCreateCheckbox("function2", 392, 120, 97, 17) $Checkbox7 = GUICtrlCreateCheckbox("function1", 288, 144, 97, 17) $Checkbox8 = GUICtrlCreateCheckbox("function2", 392, 144, 97, 17) $Checkbox9 = GUICtrlCreateCheckbox("function1", 288, 170, 97, 17) $Checkbox10 = GUICtrlCreateCheckbox("function2", 392, 170, 97, 17) GUISetState(@SW_SHOW) #EndRegion ### END Koda GUI section ### While 1 $nMsg = GUIGetMsg() Switch $nMsg Case $GUI_EVENT_CLOSE Exit EndSwitch WEnd

      As with a lot of programming, the less manual repetition done to achieve the same outcome...the better.
      I package programs for network deployment at the organization I work for. Sometimes these applications require verbose messaging to the user, and sometimes by special request we have to turn that off and deploy silently.
      The way I currently handle these 2 scenarios is this.
      I have a function that builds the splashwin display screen to variable size depending on message length, and displays the desired message to the end user.
      Then at each point throughout my script as I need to make the user aware of what is currently happening, I inject a splashwin function call with the unique message pertaining to that specific event. ie. "Installing Microsoft Office, please wait..."
      In effort to build a more universal script to handle any type of request submitted. I've incorporated a switch command of '/silent'
      If cmdlineraw detects the usage of that switch when the script is triggered it sets a variable flag, ie. $silent = "on"
      Then at every splashwin call I make, I'm prefixing it with an IF statement that checks for the flag, and then does NOT display the message if that flag is "on". Or does display it if its not. Has worked for me just fine. But while I grow my programming skills and look for more streamlined ways of handling areas I find myself creating repetition. I'm curious if I can relocate that flag check. Taking it out of every single splashwin call, and injecting it into the function itself.
      Example of how I currently display or hide the splashwin based on command line...
      If StringInStr($cmdlineraw, "/silent", 0) Then
          $SilentSwitch = "ON"
      EndIf
      If $SilentSwitch = "OFF" Then SplashWin($Uninstalling & $ProductInfo[1][0])
      Some scripts have dozens of those splashwin calls littered throughout, so Is this the best approach I can take already? Or as stated earlier, can I pull the IF statement away from the splashwin call. And left the function as a whole either activate or deactivate as a result of the command line check.

      Edit: Just realised this was posted in the wrong forum! I guess the Mods will move it to either "AutoIt General Help and Support" or "AutoIt Technical Discussion".
      Do you use type checking? Or do you choose not to type check?
      I was trying to think of the simplest way to do a type check without typing arguments more than once and I came up with:
      Func displayPerson($firstName, $lastName, $age) ; -- TYPE CHECK -- Local $typeCheck = ("" _ & IsString($firstName) _ & IsString($lastName) _ & IsNumber($age) _ ) If (StringInStr($typeCheck, "0")) Then MsgBox(16, "Type Error: displayPerson()", $typeCheck) ; -- FUNCTION -- MsgBox(0, "", $firstName & " " & $lastName & " (" & $age & ")") EndFunc The only catch with this method is that it produces a very simplistic error message. Even still, the fact that you only have to type out arguments once makes it a reasonable approach, in my opinion. The same logic can also be used for making function contracts (for example: $firstName mustn't be an empty string etc...).
      What do you think? How do you go about such things?
