Variable Verification

7 posts in this topic

So I have been in and out of AutoIt for a few years now and I've never come across a situration where I'd need to verify if an a variable is an array or not.

So here's the deal - I have a database that contains 1 table with a few different columns. When a user initially opens the script, it will see if their "username" pulled from @UserName is stored in the database (which is always unique).

If their username is not in the database, it inserts a record (using EzMySql) including their username, full name (pulled from ->

_AD_Open()

Global $adFullName = _AD_GetObjectAttribute(@UserName, "DisplayName")

Global $uSName = @UserName

_AD_Close()

<-), Time Stamp, Accept Flag (0/1) and Deny Flag (0/1).

This is all irrelevant at this point but I just wanted you to understand what I am doing here.

Anyways, I am getting to the point to where I am storing specific values from the table into variables. EzMySql will store the data in an array (IF the query finds results) however if it does not, then the variable will not be an array.

The problem is, when I run my "If statements" - if I check the variable, there is no way for me to know if the results are stored in array format or not.

Here's an example, read the comment above $LookupUser.

Func _CheckDatabase()
; Obtain user's Full Name and store as variable.

If Not _EzMySql_Startup() Then
    MsgBox(0, "Error Starting MySql", "Error: "& @error & @CR & "Error string: " & _EzMySql_ErrMsg())
    Exit
EndIf

$Pass = "D@#!$dD(#d0939kd(#Dk3093d)(#D039039ddk39dkd"

If Not _EzMySql_Open("10.3.3.11", "rug_user", $Pass, "rug", "3306") Then
    MsgBox(0, "Error opening Database", "Error: "& @error & @CR & "Error string: " & _EzMySql_ErrMsg())
    Exit
EndIf

If Not _EzMYSql_Query("SELECT * FROM accept_list WHERE Username = '" & @UserName & "';") Then
MsgBox(0, "Query Error", "Error: "& @error & @CR & "Error string: " & _EzMySql_ErrMsg())
    Exit
EndIf

If Not _EzMySql_SelectDB("rug") Then
    MsgBox(0, "Error setting Database to use", "Error: "& @error & @CR & "Error string: " & _EzMySql_ErrMsg())
    Exit
EndIf

$LookupUser = _EzMySql_FetchData()


;This is the problem - if there is no data found, $LookupUser[1] for example will not work returning an error. This function currently works but I need more functionality.

If $LookupUser == 0 Then
$sMySqlStatement = "INSERT INTO accept_list (Username,FullName) VALUES (" & "'" & $uSName & "'," & "'" & $adFullName & "');"
    If Not _EzMySql_Exec($sMySqlStatement) Then
        MsgBox(0, "Error inserting data to Table", "Error: "& @error & @CR & "Error string: " & _EzMySql_ErrMsg())
    Exit
EndIf
ElseIf $LookupUser <> 0 Then
    _CheckFlags()
    ;Call function to verify if user has accepted or not.
EndIf
_EzMySql_Close()
_EzMySql_ShutDown()
Return
EndFunc

Did you check the IsArray() function?

If you learn from It, it's not a mistake

Did you check the IsArray() function?

And also UBound() will help verifying arrays size.

Thank you both - this solved my issue entirely! I tested it using the following and ensured that I had "
#include <Array.au3>
" included.:

If IsArray($LookupUser) Then
MsgBox(0, "Variable Array Check", "Your variable is an array - hurray!")
Else
MsgBox(0, "Variable Array Check", "Your variable is not an array - awww.")
EndIf

Thanks again guys!

#include <Array.au3>
is not needed to use function "IsArray". IsArray is part of AutoIt itself.

      Howdy, this is my first post, massive fan of autoit. 
      I've searched and tried and I would just like people who are better at this than me to let me know if this is even a thing.

      I'd like to perform just a variable. For example, it would be. *see inserted code*
      So what i'm wanting is, create the constant $test, and that variable would be what is followed after the = . Then perform the _FileCreate. Then perform the variable.  Logically or in my head rather.. That variable is declared and is equal to what it is set to above, therefore just placing the variable plainly in the script, it should be equal to what it was declared as.  So what am I doing wrong, and or how can I have autoit just perform the variable.  

       
      #include <File.au3> Const $test = FileWriteLine(@DesktopDir & "\Log.txt", @CRLF ) _FileCreate(@DesktopDir & "\Log.txt") $test

      I have a script , during compilation and test execution, it worked perfectly but sometimes I am getting error as "Variable used without being declared."
       
      I understood somewhere in the branching logic this is happening.
       
      But not able to find it exactly.
       
      As I am using multiple include statements.the line number is also not giving accurately.
       

       
      Can anyone suggest what is the approach to resolve this?

      Haven't had much time to code recently. However the following thread inspired me.
      The debate about linear, parallel and binary search methods was rather interesting and, in an attempt to be diplomatic, I decided to combine @jchd's suggestion with @LarsJ's binary search example. I decided that the binary search algorithm required modification to make it more linear. As usual, 'if you invent something, it probably already exists and if it already exists, it exists for a reason'. My first attempt was not all that good. The code worked but was really a mess. I blame peer pressure (to post an example of a parallel search method).  I will delete that old code in due course.
      With a little memory jogging and a glance at the help file, the solution turned out to be quite easy: I just needed a better understanding of Euler. Further modification will be needed to work with more complicated unicode strings. The output could be returned as an array or a delimitered string. I'm not so interested in those details. I'm just going to post the algorithm for now and anyone, who wants to, can modify it to suit their needs. Both arrays must contain at least 1 element.
      Local $aFoo = [0,1,2,3,4,5,6,7,9,10,11,12,13,14,15,16,19,20,23,24,26,30,35,39,40,41] Local $aBar = [0,1,5,6,7,8,9,10,11,12,13,14,17,18,19,21,24,25,26,27,34,35,38,40] ParallelExponetialSearch($aFoo, $aBar) ; Compares two lists - returning positive matches. Each input array must be unique (individually) and in alphabetical order. Func ParallelExponetialSearch($aFoo, $aBar) Local $sFind, _ $iMin_F = -1, $iMax_F = UBound($aFoo) -1, $Lo_F = $iMin_F, $Hi_F, _ $iMin_B = -1, $iMax_B = UBound($aBar) -1, $Lo_B = $iMin_B, $Hi_B While $iMin_F < $iMax_F And $iMin_B < $iMax_B ; Toggle Arrays - Which array has most untested elements? This is the one we want to search next, ; so we can bypass more comparisons because (in theory) mismatches have a greater chance of being skipped. If $iMax_F - $iMin_F >= $iMax_B - $iMin_B Then ; $aFoo has more (or an equal number of) untested elements $Hi_F = $iMax_F $iMin_B += 1 $sFind = $aBar[$iMin_B] While $Lo_F < $Hi_F ; search $aFoo For $i = 0 To Floor(Log($Hi_F - $Lo_F) / Log(2)) $Lo_F = $iMin_F + 2^$i If $aFoo[$Lo_F] = $sFind Then $iMin_F = $Lo_F ; each match should be added to the output [perhaps an array] ConsoleWrite($sFind & " found at $aFoo[" & $Lo_F & "] = $aBar[" & $iMin_B & "]" & @LF) ExitLoop 2 ElseIf $aFoo[$Lo_F] > $sFind Then $Hi_F = $Lo_F -1 $iMin_F += Floor(2^($i -1)) $Lo_F = $iMin_F ContinueLoop 2 EndIf Next $iMin_F = $Lo_F ; minimum increment is one WEnd Else ; $aBar has more untested elements $Hi_B = $iMax_B $iMin_F += 1 $sFind = $aFoo[$iMin_F] While $Lo_B < $Hi_B ; search $aBar For $i = 0 To Floor(Log($Hi_B - $Lo_B) / Log(2)) $Lo_B = $iMin_B + 2^$i If $aBar[$Lo_B] = $sFind Then $iMin_B = $Lo_B ; each match should be added to the output [perhaps an array] ConsoleWrite($sFind & " found at $aFoo[" & $iMin_F & "] = $aBar[" & $Lo_B & "]" & @LF) ExitLoop 2 ElseIf $aBar[$Lo_B] > $sFind Then $Hi_B = $Lo_B -1 $iMin_B += Floor(2^($i -1)) $Lo_B = $iMin_B ContinueLoop 2 EndIf Next $iMin_B = $Lo_B ; minimum increment is one WEnd EndIf WEnd EndFunc ;==> ParallelExponetialSearch I hope this will be useful to someone. I believe it deserved a thread of its own!

      Afternoon!
      I have a requirement to return both a string and an array from a function so as a result I put them both into an array and returned that.  I can access them in their entirety after returning them but then I can't seem to access the array elements after this.  Should I be able to or is there a prettier way?
      #include <Array.au3> ;Memory info returned as a string and an array $memoryInfo = _getMemoryInfo() msgbox(0,"Memory Info",$memoryInfo[0]) _ArrayDisplay($memoryInfo[1],"Memory as an Array") Local $newArray[7] $memoryInfo[1] = $newArray msgbox(0,"Test element",$newArray[0]) _ArrayDisplay($newArray) Func _getMemoryInfo() Local $newArray[7] Local $array = MemGetStats() $newArray[0] = $array[0] ;% of memory in use $newArray[1] = Round($array[1]/1024 * 0.001,2) ;Total physical RAM $newArray[2] = Round($array[2]/1024 * 0.001,2) ;Availaible physical RAM $newArray[3] = Round($array[3]/1024 * 0.001,2) ;Total pagefile $newArray[4] = Round($array[4]/1024 * 0.001,2) ;Available pagefile $newArray[5] = Round($array[5]/1024 * 0.001,2) ;Total virtual $newArray[6] = Round($array[6]/1024 * 0.001,2) ;Available virtual $memoryUsage = $newArray[1] - $newarray[2] $pagefileUsage = $newArray[3] - $newarray[4] ;Output/Return Local $returnArray[2] $returnArray[0] = "Memory: " & $memoryUsage & " GB/" & $newArray[1] & " GB " & @CRLF & "Pagefile: " & $pagefileUsage & " GB/" & $newArray[3] & " GB " $returnArray[1] = $newArray return $returnArray EndFunc A bit messy but hopefully it's understandable what I'm trying to achieve.
      Thanks!

      I am having difficulties getting updated results from GUICtrlCreateInput. I wrote a small script to demonstrate what I am trying to do.
      This script reads a text file into an array and displays the Name and Number from the text file.
      The user can check a name and change the number, and the results are displayed in _ArrayDisplay.
      Only the Checked names are displayed in their original position. This is necessary for future
      plumbing.
      The problem with this script is the original number is returned, not the changed number. I cannot
      figure out how to get the updated number to be displayed.
