Set association for multiple extensions using a foreach loop/my own variable: NO WAY!

[Kenafri]

I'm tryin' to modify multiple files associations in one go like below (NOTA : VLC is already installed):

sl "I:\PS-SFTA-master"

. .\SFTA.ps1

$MediaExtensions = @(".3g2", ".3gp", ".3gp2")

foreach ($MediaExtension in $MediaExtensions){
    if((Get-FTA $MediaExtension) -ne 'VLC$MediaExtension.Document)'){ Set-FTA 'VLC$MediaExtension.Document' '$MediaExtension' -Verbose }

    Write-Host "=========================================="
    Get-FTA $MediaExtension -Verbose
    Write-Host ""
}

VERBOSE: ProgId: VLC$MediaExtension.Document
VERBOSE: Extension/Protocol: $MediaExtension
VERBOSE: Write Registry Protocol: $MediaExtension
VERBOSE: Remove Protocol UserChoice Key If Exist: HKCU:\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\$MediaExtension\UserChoice
VERBOSE: Write Reg Protocol UserChoice OK
==========================================
VERBOSE: Get File Type Association for .3g2
WMP11.AssocFile.3G2

VERBOSE: ProgId: VLC$MediaExtension.Document
VERBOSE: Extension/Protocol: $MediaExtension
VERBOSE: Write Registry Protocol: $MediaExtension
VERBOSE: Remove Protocol UserChoice Key If Exist: HKCU:\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\$MediaExtension\UserChoice
VERBOSE: Write Reg Protocol UserChoice OK
==========================================
VERBOSE: Get File Type Association for .3gp
WMP11.AssocFile.3GP

VERBOSE: ProgId: VLC$MediaExtension.Document
VERBOSE: Extension/Protocol: $MediaExtension
VERBOSE: Write Registry Protocol: $MediaExtension
VERBOSE: Remove Protocol UserChoice Key If Exist: HKCU:\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\$MediaExtension\UserChoice
VERBOSE: Write Reg Protocol UserChoice OK
==========================================
VERBOSE: Get File Type Association for .3gp2
WMP11.AssocFile.3G2

$MediaExtension = ".3g2"

if((Get-FTA $MediaExtension) -ne 'VLC$MediaExtension.Document'){ Set-FTA 'VLC$MediaExtension.Document' '$MediaExtension' -Verbose }
Write-Host "=========================================="
Get-FTA $MediaExtension -Verbose

VERBOSE: ProgId: VLC$MediaExtension.Document
VERBOSE: Extension/Protocol: $MediaExtension
VERBOSE: Write Registry Protocol: $MediaExtension
VERBOSE: Remove Protocol UserChoice Key If Exist: HKCU:\Software\Microsoft\Windows\Shell\Associations\UrlAssociations\$MediaExtension\UserChoice
VERBOSE: Write Reg Protocol UserChoice OK
==========================================
VERBOSE: Get File Type Association for .3g2
WMP11.AssocFile.3G2

Function Set-FTA seems to not read/convert my custom variable ($MediaExtension) correctly

================================================================

But all things go well with one extension at the time :

Set-FTA 'VLC.3g2.Document' '.3g2' -Verbose

VERBOSE: ProgId: VLC.3g2.Document
VERBOSE: Extension/Protocol: .3g2
VERBOSE: Write Registry Extension: .3g2
VERBOSE: Remove Extension UserChoice Key If Exist: Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.3g2\UserChoice
VERBOSE: Write Reg Extension UserChoice OK

Your help will be appreciated. Thanx

PS : Unecessary verbose output have been removed

Hello. Use doble quotes. You're using single quotes which does not allow PowerShell to get the variable value, instead it's passing a literal string.

Hello ! You kidding me : works like a charm !

$MediaExtensions = @(".3ga", ".3gp", ".3gp2")

foreach ($MediaExtension in $MediaExtensions){
    # if ((Get-FTA .mp3) -ne 'VLC.mp3.Document'){ Set-FTA 'VLC.mp3.Document' '.mp3' | Out-Null }
    Write-Host "Définition de l'association du fichier $MediaExtension (VLC$MediaExtension.Document)"
    if ((Get-FTA "$MediaExtension") -ne "VLC$MediaExtension.Document"){ Set-FTA "VLC$MediaExtension.Document" "$MediaExtension" -Verbose }

    Write-Host "=========================================="
    Get-FTA $MediaExtension -Verbose
    Write-Host ""
}
