Powershell редактирование нескольких защищенных паролем файлов Word

Question

Я нашел приведенный ниже код Powershell, который отлично работает для редактирования нескольких документов Word, однако, когда документы защищены паролем, это не удается.

1. Я знаю пароль (который одинаков для всех файлов).

2. Я изменил строку 86 для передачи переменной пароля (запрошено пользователем ранее в сценарии).

   086 Функция processDoc ($ pass) {

3. Строка 87 затем использует переменную в том, что я понимаю (я могу ошибаться), чтобы иметь правильный формат .

   087 $ doc = $ word.Documents.Open ($ _. FullName, $ null, $ false, $ null, $ pass, $ null, $ null, $ pass)

4. Я вызываю строку 96, передавая переменную пароля.

   096 $ countr = processDoc ($ passwd)

Это не работает, и я не знаю почему. Я не программист по профессии, поэтому, скорее всего, делаю глупости.

Может кто-нибудь посоветовать, пожалуйста? С нетерпением жду снисходительных комментариев: -)

Это было решение ...

Function processDoc {
$doc = $word.Documents.Open($_.FullName)

# I added this bit
# https://msdn.microsoft.com/en-us/vba/word-vba/articles/document-unprotect-method-word
# Check for file protection
If ($doc.ProtectionType -and ($doc.ProtectionType -ne 'wdNoProtection') ) {
    # Unprotect file with password
    if ($doc.Unprotect) {
        $doc.Unprotect($FilePassword)
    } 
} 

$count = findAndReplaceWholeDoc $doc $textToReplace

# I added this bit
# Reprotect file with 'wdAllowOnlyReading'
# https://msdn.microsoft.com/en-us/vba/word-vba/articles/wdprotectiontype-enumeration-word
$doc.Protect(3, $null, $FilePassword)

$doc.Close([ref]$true)
return $count

}
