A better way of Randomising.


Recommended Posts

Hey Guys.

Happy Christmas and Merry new Year and all that..

I'm currently automating our entire system for end-2-end testing. I have about 12 Complex scripts all joined together in a GUI and it all works.

But I want to bring down the amount of lines of code that I used (I Started coding these script without any knowledge of coding/scripting so bear with me..)

Currently, I am generating a random number with the following code..

IniWrite(@ScriptDir & "\Iteration.ini ", "Boat Details", "Engine" , Random(111, 999, 1) & Chr(Random(Asc("A"), _
Asc("Z"), 1)) & Chr(Random(Asc("A"), Asc("Z"), 1)) & Random(111, 999, 1) & Chr(Random(Asc("A"), Asc("Z"), 1)) & _
Chr(Random(Asc("A"), Asc("Z"), 1)) & Chr(Random(Asc("A"), Asc("Z"), 1)) & Chr(Random(Asc("A"), Asc("Z"), 1)) & _
Random(111, 999, 1) & Chr(Random(Asc("A"), Asc("Z"), 1)) & Chr(Random(Asc("A"), Asc("Z"), 1)))

Please note that the amount of characters is critical for my tests.

Now the question, Is there a better way of doing this?

Thanx for the assist.

Kamakazy,

If I was going to do something like that I would structure it like this

IniWrite( @ScriptDir & "\Iteration.ini ", "Boat Details", "Engine" , _num() & _
                                                                     _chr() & _
                                                                     _chr() & _
                                                                     _num() )   ; etc for as long as you require


func _chr()
    return Chr(Random(Asc("A"), Asc("Z"), 1))
EndFunc

func _num()
    Random(111, 999, 1)
endfunc

just for readability.

edit: it does NOT bring down the # of lines of code but it's a hell of a lot easier to read. The # of lines of source should be considered only after readability and maintainability, if at all.

func _num()
Return Random(111, 999, 1)
endfunc

will work even better ;-)

This is a pretty easy error to make and AutoIt won't bark:

Local $a = fct()

Func fct()
Random(0, 9, 1) ; or whatever without Return
EndFunc

      Hi guys!
       
      I need some help here, is there a way to use Random with While? 
      I need this script to run in between 1 and 4 times but I dont know how to do it, can you please help me?
       
      dim $i=1
      While $i<=4
      Sleep(3000)
      Send("{LWINDOWN}r{LWINUP}")
      Sleep(3000)
      Send("C:\Users\123\Catalogos\tags.txt{ENTER}")
      Sleep(3000)
      WinActivate("tags: Bloc de notas","")
      Sleep(3000)
      Send("{SHIFTDOWN}{END}{SHIFTUP}{CTRLDOWN}c{CTRLUP}{DEL}{DEL}")
      Sleep(3000)
      Send("{CTRLDOWN}g{CTRLUP}{ALTDOWN}{F4}{ALTUP}")
      Sleep(3000)
      Send("{CTRLDOWN}v{CTRLUP}{SPACE}")
      $i=$i+1

      I need a random string generator which creates 15 letters/numbers.
      How can I make that?
    • By Anas
      Hi,
      I've this script (removed unrelated parts) that generate a set of random chars for a password. It gets launched from a network share by Task Scheduler at a specific time for all PC's, then it relaunches itself from the local drive.
       
      Global $LocalToolsDir = @ProgramFilesDir & '\Tools' Start() Func Start() If Not StringInStr(@ScriptFullPath, $LocalToolsDir, 2) Then Exit RunLocaly() Sleep(Random(1, 1800, 1) * 1000) $NewPass = GeneratePass() EndFunc Func GeneratePass() Local $Pass For $i = 1 to 8 $R = Random(0,1.5) If $R > 1 Then $Chr = Random(0,9,1) ElseIf $R < 0.5 Then $Chr = Chr(Random(Asc("A"), Asc("Z"), 1)) Else $Chr = Chr(Random(Asc("a"), Asc("z"), 1)) Endif $Pass &= $Chr Next Return $Pass EndFunc Func RunLocaly() Local $Run = 1, $LocalApp = $LocalToolsDir & '\' & @ScriptName If Not FileExists($LocalApp) Then $Run = FileCopy(@ScriptFullPath, $LocalToolsDir, 1 + 8) If $Run Then Run($LocalApp, $LocalToolsDir) EndFunc  
      The problem is that many PC's ends up with the same password(s).
      e.g. 10 PC's have (abc123) as a Password, and another 10 have this (def456)
      Any idea why?

      Got a simple question is it possible to have lets say 10 functions and use the random function to randomly pick one of them? If so could anyone please make a tiny example?
       
      Tyvm in advance
