Automatic Firmware Updates - SQLite & WMI

Author:

Script Function:
Query local device WMI info and perform a SQL lookup to check for firmware updates. The SQL database contains
device models, current firmware version, and the path to the update package. This script looks for the firmware
version based on the device model, and then copies the installer to the host drive. The script then performs a
silent install of the firmware update all the while preventing an accidental shutdown. This script has a verbose
log which gets copied to a network location if there's a problem. If it's successful the log writes a single
line to a master log in the same network location reporting it's success. Once the update is complete, the
installer file is deleted, as well as the local log file.
Version Notes:
1.0.03 - Adjusted final write to local log so that the $FirmwareDBResult is written in the log.
1.0.02 - Added processwait() to script to prevent premature script completion
1.0.01 - Added values to BIOSString dump in addition to names
1.0.00 - Initial complete version

      How do I work with 2D arrays.  I've tried this but get errors.
      Local $aTest[4][4] = [[1,2,3,4],[5,6,7,8],[9,10,11,12],[13,14,15,16]]
      ;$aTest[0][] = [10,11,12]  ; Error at []
      Local $sTest = ""
      For $i = 0 To UBound($aTest)-1
        Local $aExtract = _ArrayExtract($aTest,$i,$i)
        $sTest = $sTest & MyTest($aExtract)
      Next
      Func MyTest($aTemp)
        _ArrayDisplay($aTemp)
        ; Error at    v $aTemp
        Return String($aTemp[0]) & " - " & String($aTemp[1]) & " - " & String($aTemp[2]) & @CRLF
      EndFunc

      I have been testing AutoIt 3.3.14.3 with SQLite, and the Help File examples.  The examples that I have tested are throwing errors or not doing anything.  I have sqlite3.dll, sqlite3_x64.dll, and sqlite3.exe in the directories with the testing script.  I am copying the examples directly from the help file into a test script for testing with no edits.  The _SQLite_GetTable2d example is returning an error ("Library used incorrectly") with each _SQLite_Exec command.  The _SQLite_FastEncode example returns an empty dialog box.  The _SQLite_Exec example only prints out the SQLite version, and nothing else in the SciTE console.  Currently, I'm still searching for what is causing this issue.  I'm on Windows 7 Enterprise 64-bit.  Is anyone else having this issue?

      Greetings,
        I have SQLite setup within my AutoIT program...I'm trying to accomplish what should be a relatively simple task.  I want to be able to return an array of 'table' names for an established database...I believe this might be possible using the '_SQLite_SQLiteExe' command...since it seems to be able to access SQLite schemas...?  The ".tables" command is one of them...if I am not mistaken that command returns a list of all table names in the active database.
        I am attempting the following:
      #include <SQLite.au3> #include <SQLite.dll.au3> Global $hDb, $sIn, $sOut ... $sIn = ".tables" & @CRLF _SQLite_SQLiteExe($hDb, $sIn, $sOut) if @error == 0 Then ;Show Table (using SQLite3.dll) Else if @error == 2 Then ConsoleWrite("ERROR: Sqlite3.exe file not found" & @CRLF) Else ConsoleWrite("ERROR: @error=" & @error & " when calling _SQLite_SQLiteExe" & @CRLF) EndIf ;@error is "2"...OR NOT... EndIf ;@error is "0"...OR NOT... ...   The error being thrown is "ERROR: Sqlite3.exe file not found" ...
        Am I required to have the Sqlite3.exe installed in my directory (i.e. @ScriptsDir)...???  I do not have it in there at present because I did not believe it was necessary with the 'include' calls to "SQLite.au3" and "SQLite.dll.au3"...any advice appreciated.  Thanks in advance. 
      Regards

      Hi all,
      I have a bit of code that works on my old Win10 PC, that fails on my new Win10 PC, and I think the only significant difference is the version of Autoit - old PC has 3.3.12, new has 3.3.14.
      I couldn't find anything mentioned in the change logs though, so perhaps I'm wrong.
      Anyway, the code to replicate my issue is:
      Test('username', 'DOMAIN') ; THIS ERRORS: ;Test('localun', 'DOMAIN') ; THIS ERRORS: ;Test(' ', ' ') ; THIS ERRORS: ;Test('', '') ; THIS ERRORS: ;Test('localun', '') ; THIS ERRORS: ;Test('', 'DOMAIN') Func Test($un, $dom) $compName = 'PCNAME' $FullName = '.' $Description = '.' ; get the WIM object $objWMIService = ObjGet("winmgmts:\\" & $compName & "\root\cimv2") ; get default user full name and description $objAccount = $objWMIService.Get("Win32_UserAccount.Name='" & $un & "',Domain='" & $dom & "'") If IsObj($objAccount) Then $FullName = $objAccount.FullName $Description = $objAccount.Description EndIf ConsoleWrite($FullName & @CRLF) ConsoleWrite($Description & @CRLF) Return EndFunc  
      On my old PC this code will output just . and . for each of those line currently commented out. Which is fine.
      On my new PC any of those commented out lines of code cause an error, and the script won't even compile.
      $objAccount = $objWMIService.Get("Win32_UserAccount.Name='" & $un & "',Domain='" & $dom & "'") $objAccount = $objWMIService^ ERROR I'm very much a newb with the WMI stuff and objects, but it looks like the .Get property is failing when either $un or $dom aren't valid in v3.3.14, whereas in 3.3.12 the .Get would fail to return an object, which is then caught by the If statement.
      Am I on track with this? Is there some new/better way to code the example so that 3.3.14 will compile it?

      My esteemed Autoits I need your help once again.
      I'm trying to figure out how to create a loop that gets 1 value from an array and repeats until each value from the array has been used. I have never used arrays before and I know once I learn more things should get easier for me. 
      Here is what Im trying to do:
      -Have an array of values that determine what application i log into. ex: app1, app2, app3, app4 etc.
      -Have a loop that repeats a process sequentially using each value in the array to finish the process for each app1, app2, app 3 and so forth. I have 30 apps that I need to update on a regular basis and getting this sorted out is what I perceive to be the best way to do it.
      Here is my feeble attempt that obviously fails:
      #include <msgboxconstants.au3>
      #include <Constants.au3>
      #include <array.au3>
      Login()
      Func Login()
          local $array[30] = ["10", "11", "12",etc etc]
          ;;Local $site = InputBox("ERx Site","What site do you want to login as?","","")
          Local $userid = InputBox("ERx Login", "What is your username?", "", "")
          Local $Passwd = InputBox("Security Check", "Enter your UAT password.", "", "*")
      for $1 = 1 to 30(I need to do the same steps in 30 different apps)
      run("Z:launch.exe")
      WinWaitActive("Input")
      Send (Sequential ARRAY VALUE HERE)
      Send("{ENTER}")
      WinWaitActive("window")
      Send($userid)
      Send("{TAB}")
      send($Passwd)
      Send("{ENTER}")
      WinWaitActive("[CLASS:SunAwtDialog]")
      Sleep(500)
      WinClose("Home Page")
      Next
      EndFunc
       
      your help is greatly appreciated.
      Thanks for your time
