怎么给文件设置密码:如何为PDF文件导出设置密码(vba save as pdf with pword)-边看边学

我需要添加提取 PDF 的密码。

Dim FileName As String
Dim FilePath As String
FileName = Me.Full_Name & "_" & Me.ID
FilePath = "C:\Users\Desktop\" & FileName & ".Pdf"
DoCmd.OutputTo acOutputReport, "Report", acFormatPDF, FilePath
MsgBox "Exported Successfully"

这里有一个使用 Ghostscript 的解决方案。首先像你已经做的那样打印你的 pdf,然后调用下面的函数。Ghostscript 在许可协议下是免费的,afaik

Public Function fctPDO_Print_pdf_GhostScript(strFile_for_pdf As String, Optional strUserPword As String = "", Optional strOwnerPword As String = "") As String
        ' http://www.herber.de/forum/archiv/1164to1168/1165503_Zusammenfuehren_von_PDF_Files.html#1165503
        ' https://stackoverflow.com/questions/49953421/ghostscript-with-aes-256-pword-protection-for-pdf-2-0-documents
        ' PDO: Prints a pdf (originally multi-pdf). Requires Ghostscript, and read/write rights.
        '      Existing files are overwritten without asking.
        '      Provide both pwords to lock. Ghostscript does rc4 , being comparatively unsafe.
        '
