Automatic creation of GUI Radio Buttons based on input from a file

I am automating the testing of a video player. I search a file for ".mp4" and want to create a GUI with radio buttons to select what video to play. The number of videos can change based on the user's library so this must be created automatically.  I have searched for how to accomplish this and there are several posts out there that help a little but I can't figure out the solution. I pulled the offending code from my main script and created the file below to make this easier to read. I am sure one of our experts here can help!

#include <MsgBoxConstants.au3>
#include <StringConstants.au3>
#include <array.au3>
#include <File.au3>
#include <GUIConstantsEx.au3>

Local $sMediaFile = "D:\MediaFiles\MediaFiles.txt"
Local $iStrReturn = 0
Local $aText
Local $aArrayFile
Local $iMax = 6 ;Default number of Videos - 1 for the array counter
Local $aVideoName[$iMax] = [0]
Local $sCheckBox1
Local $iT = 0, $iVideoCount = 0, $iCount
Local $ix = 0
Local $iy = 0
Local $idClose1
Const $iL = 10  ; Count from Left for GUI so all buttons line up

;   Read a list of video file names and create a GUI with Radio Buttons to select a single video.
;   Problem: We don't know how many video names will be in the text file, so we can't hard code Case Statements & their variables

; Put the Video File Names into an Array
_FileReadToArray($sMediaFile, $aArrayFile)
For $a = 1 To $aArrayFile[0]    ; Step through the array looking for .mp4
    If StringInStr($aArrayFile[$a], ".mp4") Then
        $iVideoCount = $iVideoCount + 1
        $aText = StringSplit($aArrayFile[$a],"\\")  ; This video player reads double backslashes
        For $a1 = 1 to $aText[0]
        ; Check that the array is big enough
            If StringInStr($aText[$a1], ".mp4") Then
                ;MsgBox(0,"","Video is " & $aText[$a1])
                If UBound($aVideoName) = $iVideoCount Then
                    ; Resize the array when $iCount is equal to the element count in the array to prevent subscript error
                    ReDim $aVideoName[$aVideoName[0] + $iMax]

                $aVideoName[$iVideoCount] = $aText[$a1]; add data to new index element

                $aVideoName[0] = $a1 ; update the index count for future reference

                ;   The idea is to create a GUI width to accommodate long video file names
                $it = StringLen($aVideoName[$iVideoCount])
                If $iT > $ix Then
                    $ix = $iT
; Move backwards through the array deleting blank rows
For $iCount = UBound($aVideoName) - 1 To 0 Step -1
    If $aVideoName[$iCount] = "" Then
        _ArrayDelete($aVideoName, $iCount)
;   Create the GUI - Names and Radio Button counts will vary - How do I do this?
;Local $aVarName[$aVideoName[0]]
Local $iRows = UBound($aVideoName, $UBOUND_ROWS)
$iRows = $iRows -1
$aVideoName[0] = $iRows
; Prep the GUI to display the FileNames with Radio Buttons - Can only select one at a time.
$a = 0
$ix = $ix + 200
$iy = ($aVideoName[0] * 30) + 60
$hGUI = GUICreate("Videos", $ix, $iy)
;$iT = $iT+30

;   Create the variable names for the Case statement - Video count may change so Video Names displayed and GUICtrlCreateRadio count may change.

;~ For $a = 1 to $aVarName[0]
;~  If UBound($aVarName) = $aVarName Then
;~      ; Resize the array when $iCount is equal to the element count in the array to prevent subscript error
;~      ReDim $aVarName[$aVarName[0] + $iMax]
;~  EndIf

;~  Assign("$bVideoName" & $a, $a)
;~  Local $aVarName[$a] = Eval($bVideoName[$a])
;~ ;    $aVarName[$a] = GUICtrlCreateRadio($aVarName[$a], $iL, $iT)
;~ Next
$iCount = 1
;MsgBox(0,"","VideoName[0] is "&$aVideoName[0])
Local $bVideoName1
If $iCount < $aVideoName[0] Then
    $bVideoName1 = GUICtrlCreateRadio($aVideoName[$iCount], $iL, $iT)
    GUICtrlSetState($bVideoName1, $GUI_CHECKED)
    $iT = $iT+30
$iCount = $iCount + 1
If $iCount <= ($aVideoName[0]) Then

        ;Case $bVideoName6 <- Fails because there are only 5 videos - Need variable $bVideoNames

        ;Case $bVideoName7 <- Fails because there are only 5 videos

        Case $idClose1
            $bVideoName1 = GUICtrlRead($bVideoName1)
            $bVideoName2 = GUICtrlRead($bVideoName2)
            $bVideoName3 = GUICtrlRead($bVideoName3)
            $bVideoName4 = GUICtrlRead($bVideoName4)
            $bVideoName5 = GUICtrlRead($bVideoName5)
            ;$bVideoName6 = GUICtrlRead($bVideoName6)
            ;$bVideoName7 = GUICtrlRead($bVideoName7)
MsgBox(0,"","Case " & $nMsg & " was selected.") ;   Always returns 8. ???

This is the "MediaFiles.txt" file I am reading:


I'm sure I have several mistakes (or poor coding methods) in my AutoIt file.

Thanks Water. I am reviewing your code to try to understand it!

Of course I am reading a .json file and not a .ini file so I will have to replace the IniReadSection lines...

      MS Splash Screens
      The office 2016/17 office suite has made many people turn heads with its functions and especially their splash screen.
      I now present to you, the MS Style Splash Screen. For Rookies, Novices and anyone who wants a ready made splash screen for your gui application.

      You can now download it and also try it out yourself.
      You have three colors to choose from:
      All three colours are from the famous programs.
      I also included the KODA form to you can have freedom with this splash screen.
      Note: the KODA form does not have the three colours as well as the correct blue. 

      Have fun and enjoy.
      I will update the splash to add the automated 3 dots animation at a later stage.

      A gui splash screen. Themed after the famous MS Office Suite.
      Three colours to choose from, Red, Blue and Green.
      You can change the labels to your own application.

      Also bundled with this is the KODA form. So you can open up and see the basic structure of this splash screen.

      Hello all,
      I've been trying to figure out how to launch Google Chrome in the background (hidden) but it doesn't seem possible. I've tried the following methods:
      ShellExecute("C:\Program Files (x86)\Google\Chrome\Application\chrome.exe", "", "", "", @SW_HIDE) Also I've tried:
      ShellExecute(@ComSpec, "/c start chrome.exe","","",@SW_HIDE) Lastly I tried:
      RunWait('"'&@ProgramFilesDir&'\Google\Chrome\Application\chrome.exe" --silent-launch',@ScriptDir)  
      But all of them launch my chrome browser without hiding it. Does anyone know a workaround for this or if AutoIT just can't Chrome? 
      Bonus points if you know how to make it launch chrome hidden and make it go to https://www.autoitscript.com
      Thank you,

      I have a working program currently driven largely through menu selections. I would like to add a toolbar where most of the tollbar button actions are basically the same as menu items, but quicker to access. I have been wading around in toolbar examples, MSDN pages etc, it's clearly going to be a bit of a slog to get everything right, including tooltips etc. I thought I would start with something simple to prove the principle.
      Using bits from the help file examples I have a small program that successfully displays a toolbar. However, what seemed like the most elegant way to deal with the button commands does not seem to work. My understanding was that a toolbar button fires a WM_COMMAND message, with the command Id set by the second parameter in the call to
      _GUICtrlToolbar_AddButton ( $hWnd, $iID, $iImage)
      so I though it would be a good idea to set this Id to the same value as my menu item Id; then it would run the same task which is what I wanted. This did not work. I am using message loop mode and would like to stick with this because some of my scripts run hardware at the same time as the gui; it is easier if I don't have to worry about code being interrupted with the hardware in an unknown state . So I added a handler for WM_COMMAND, with some cribbed display code to try and see why. The toolbar button defintely fired a WM_COMMAND message and the Id looked the same, so no explanation there.
      I guess the issue is with GUIGetMsg() which may be constructed to ignore all but a limited number of control handles, i.e. those made with the GuiCtrlCreate... commands; this is speculation.
      I would dearly love to find a tidy way to get around this. Having some controls handled in the message loop and some in a WM_COMMAND handler, performing the same task, feels ugly. I would be very grateful for further insight from someone experienced with handling a toolbar. Perhaps I should be trying to fire the menu item. I have attached a code snippet to try and illustrate the issue.

      Hello all,
      I've been working on 4 standalone scripts. They each have their own GUI and are now independent .exe's. But instead of having 4 separate icons on my computer, is it possible to put them all together into one .exe?
      What I want is one interface with tabs. Each script's GUI would be on their own respective tab. Is this possible?
      The different scripts don't need to communicate with one another. I just want them all in one .exe.
      I can't find this anywhere... Any help would be greatly appreciated. Thank you!
