If statement detecting a string

6 posts in this topic

Hi guys, I have a box that decides the number of runs my script will make. Since I'm trying to make my GUI Idiot-proof, I want to prevent them from putting anything stupid like 1a into the the trials column.

My current code:

$numTrials = GUICtrlRead($Edit_1)



If $numTrials<> "" AND $numTrials<> 0 AND $numTrials<>String Then



For $i=1 to $numTrials Step 1

RunScript()

Next



Exit

Else

MsgBox(64, "Error","Please Enter All Fields")

EndIf

The problem is that my script gives me an error for when $numTrials is a string like 1a23sd.

Is there a way I can avoid this error?

Thanks,

Athos

If you're using an Input control then you can do it this way.

GUICtrlCreateInput("", 10, 5, 300, 20, BitOr($ES_LEFT, $ES_AUTOHSCROLL, $ES_NUMBER))

The style setting $ES_NUMBER will let it only accept numbers in the control.


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.

Hi, Athos. If I am understanding you correctly, you're wanting the Edit1 control to only accept numbers? If so, look at the 6th option in GuiCtrlCreateEdit (style). You can set this to $ES_NUMBER like so.

#include <GUIConstantsEx.au3>
#include <EditConstants.au3>

Local $myedit, $msg
GUICreate("Test") ; will create a dialog box that when displayed is centered
$myedit = GUICtrlCreateEdit("", 8, 48, 425, 385, $ES_NUMBER)
    GUISetState()
    While 1
        $msg = GUIGetMsg()
        If $msg = $GUI_EVENT_CLOSE Then
   ExitLoop
  EndIf
    WEnd
    GUIDelete()

√-1 2^3 ∑ π, and it was delicious!

Hey that's a pretty good solution, Thanks Brewman :) Edit, you too JLogan

Still, I wonder what would have worked as an if statement solution. Is String not the correct way of handling strings?

String converts things INTO strings, it doesn't tell you if they are strings or not, IsString will tell you if it's a string.

You can also use regex to validate answers.

for example

;enter a 2-4 digit number

$sNotNumber = 'abracadabr'

$iTooBig = 32151235

$iTooSmall = 1

$iOkeyDokey1 = 12

$iOkeyDokey2 = 1234

_test($sNotNumber)

_test($iTooBig)

_test($iTooSmall)

_test($iOkeyDokey1)

_test($iOkeyDokey2)

Func _test($value)

If StringRegExp($value, '^(?:[0-9]{2,4})$') Then

MsgBox(0, $value, "Valid")

Else

MsgBox(0, $value, "InValid")

EndIf
EndFunc

      Hi all,
      I got this code and would like to be able to change Baud Rate and instead of sending character by character i would like to be able (if possible) to send whole string. But i don't know how to change it.
      I am taking input from file and processing whole line (this is done in FilesHandling.au3).
      To execute this i am just calling SendData("FileName", int) in "main" script.
      Any help very appreciated.
      #include <WinAPI.au3> #include <Array.au3> #include "FilesHandling.au3" ;init DLL function, we need handle to call the function $h = DllCall("Kernel32.dll", "hwnd", "CreateFile", "str", "\\.\COM19", "int", BitOR($GENERIC_READ,$GENERIC_WRITE), "int", 0, "ptr", 0, "int", $OPEN_EXISTING, "int", $FILE_ATTRIBUTE_NORMAL, "int", 0) $handle=$h[0] Func SendData($FileName, $LineNumber) ;string to be send $c = readFile($FileName, $LineNumber) $cLenght = StringLen($c) $aArray = StringSplit($c, "") ;_ArrayDisplay($aArray, "", Default, 64) For $i = 1 To $cLenght writeChar($handle, $aArray[$i], $cLenght) Next ;move to next line writeChar($handle, @CR,1) EndFunc ;write a single char func writeChar($handle,$c,) $stString = DLLStructCreate("char str") $lpNumberOfBytesWritten = 0 DllStructSetData($stString, 1, $c) $res = _WinAPI_WriteFile($handle, DllStructGetPtr($stString, "str"), 1,$lpNumberOfBytesWritten) if ($res<>true) then ConsoleWrite ( _WinAPI_GetLastErrorMessage() & @LF) EndIf EndFunc

      I need a random string generator which creates 15 letters/numbers.
      How can I make that?

      Hi guys,
      I am pretty bad with regex, and am having some trouble trying to come up with an expression for a certain type of string. Basically I want to be able to tell if a string is of the format:
      AA#####A
      Where the A's are any letter from A-Z and the #'s are any digit from 0-9.
      I've been playing around with a regex tester online for a while but I can't really seem to grasp the concept very well. Could anyone give me any tips?
      This isn't exactly an AutoIt specific question which is why I didn't post it in General Help & Support.

      Hi everybody,
      i have a question related to strings items in an Array and sorting. Maybe someone can advice me how to solve the issue.
      I have an Array of strings, every item of the Array is as following:
      INFO [13.06.2017 11:48:01] [Thread-13] [ConGenImpUsb -> waitForConnection]  INFO [07.06.2017 08:55:44] [main] MDU5 - Ver 5.1x I want to sort the item in the array by date and time, is there any function which allows me to sort by date/time?
      Thanks in advance
