Da ich nicht in Powershell-Erfahrung habe ich nicht verstehen, die Metod rufen sie am Skript an.

Answer 1

Ich bin noch neu in Powershell selbst, so kann nicht speziell beantworten, was den Fehler verursacht hat, aber ich denke, ich habe die Lösung gefunden. Es schien nur mit der Excel-Konvertierung zu sein. Die Word- und PPT-Conversions funktionierten einwandfrei. Ich habe den Code für diesen Teil geändert und es scheint jetzt zu funktionieren:

$folderpath = $(get-location) 
Add-type -AssemblyName office 
#Convert Word formats to pdf 
$wdFormatPDF = 17 
$word = New-Object -ComObject word.application 
$word.visible = $false 
$fileTypes = "*.docx","*doc" 
$wordFiles = Get-ChildItem -path $folderpath -include $fileTypes -Recurse 
foreach ($d in $wordFiles) { 
$path = ($d.fullname).substring(0,($d.FullName).lastindexOf(".")) 
"Converting $path to pdf ..." 
$doc = $word.documents.open($d.fullname) 
$doc.saveas([ref] $path, [ref]$wdFormatPDF) 
$doc.close() 
} 
$word.Quit() 
#Convert Excel formats to pdf 
$xlFixedFormat = "Microsoft.Office.Interop.Excel.xlFixedFormatType" -as [type] 
$excelFiles = Get-ChildItem -Path $folderpath -include *.xls, *.xlsx -recurse 
$objExcel = New-Object -ComObject excel.application 
$objExcel.visible = $false 
foreach($wb in $excelFiles) 
{ 
$filepath = Join-Path -Path $folderpath -ChildPath ($wb.BaseName + ".pdf") 
$workbook = $objExcel.workbooks.open($wb.fullname, 3) 
$workbook.ActiveSheet.PageSetup.Orientation = 2 
$objExcel.PrintCommunication = $false 
$workbook.ActiveSheet.PageSetup.FitToPagesTall = $false 
$workbook.ActiveSheet.PageSetup.FitToPagesWide = 1 
$objExcel.PrintCommunication = $true 
$workbook.Saved = $true 
"saving $filepath" 
$workbook.ExportAsFixedFormat($xlFixedFormat::xlTypePDF, $filepath) 
$objExcel.Workbooks.close() 
} 
$objExcel.Quit() 
#Convert Powerpoint formats to pdf 
$ppFormatPDF = 2 
$ppQualityStandard = 0 
$p = new-object -comobject powerpoint.application 
$p.visible = [Microsoft.Office.Core.MsoTriState]::msoTrue 
$ppFiletypes = "*.pptx","*ppt" 
$ppFiles = Get-ChildItem -path $folderpath -include $ppFiletypes -Recurse 
foreach ($s in $ppFiles) { 
$pppath = ($s.fullname).substring(0,($s.FullName).lastindexOf(".")) 
"Converting $pppath to pdf ..." 
$ppt = $p.presentations.open($s.fullname) 
$ppt.SavecopyAs($pppath, 32) # 32 is for PDF 
$ppt.close() 
} 
$p.Quit() 
$p = $null
