    Opening PDFs linked in Access database on an SQL Server


    I have an Access database on an Microsoft SQL Server. The database has fields that contain PDFs. A form in the database has a button to PDFs that are linked to the database. When clicking on the button the selected PDF opens with Acrobat Reader DC. When the viewed PDF is closed you are returned to the Access Form
    There are 5 different logins to the SQL Server. These are set up to segment the users by geographical location.
    On two of the five logins the viewing of the PDFs work automatically. On the other three logins when you click the button to view the PDF you must then use a Ctrl+Alt to view the PDFS.
    Does anyone know why the programs works well on two of the server logins, and not on the other three logins?
    Thank you in advance for any help you could give me.

    I extract the pdf from the table to c:\temp\File.pdf
    then open it with the code below:
    const kPDFfile = "c:\temp\File.pdf"
    'ExtractPdfFile code here
    OpenNativeApp kPDFfile


    Paste this code into a module, and it will open ANY file in its native application.
    In a form put the field and a button to open it.


    if the file is myFile.pdf, will open it in acrobat
    if the file is myFile.doc, it will open the doc in Word
    if its just a file path, it will open in file explorer.
    etc..


    paste this code into a module
    Code:
    'Attribute VB_Name = "modNativeApp"
    'Option Compare Database
    Option Explicit
    Code:
    Private Declare Function ShellExecute Lib "shell32.dll" Alias "ShellExecuteA" (ByVal hwnd As Long, ByVal lpszOp As String, ByVal lpszFile As String, ByVal lpszParams As String, ByVal lpszDir As String, ByVal FsShowCmd As Long) As Long
    Private Declare Function GetDesktopWindow Lib "user32" () As Long
    Const SW_SHOWNORMAL = 1
    Const SE_ERR_FNF = 2&
    Const SE_ERR_PNF = 3&
    Const SE_ERR_ACCESSDENIED = 5&
    Const SE_ERR_OOM = 8&
    Const SE_ERR_DLLNOTFOUND = 32&
    Const SE_ERR_SHARE = 26&
    Const SE_ERR_ASSOCINCOMPLETE = 27&
    Const SE_ERR_DDETIMEOUT = 28&
    Const SE_ERR_DDEFAIL = 29&
    Const SE_ERR_DDEBUSY = 30&
    Const SE_ERR_NOASSOC = 31&
    Const ERROR_BAD_FORMAT = 11&
    
    Public Sub OpenNativeApp(ByVal psDocName As String)
    Dim r As Long, msg As String
    r = StartDoc(psDocName)
    If r <= 32 Then
        'There was an error
        Select Case r
            Case SE_ERR_FNF
                msg = "File not found"
            Case SE_ERR_PNF
                msg = "Path not found"

            Case SE_ERR_OOM
                msg = "Out of memory"
            Case SE_ERR_DLLNOTFOUND
                msg = "DLL not found"
            Case SE_ERR_SHARE
                msg = "A sharing violation occurred"

                msg = "Incomplete or invalid file association"
            Case SE_ERR_DDETIMEOUT
                msg = "DDE Time out"
            Case SE_ERR_DDEFAIL
                msg = "DDE transaction failed"
            Case SE_ERR_DDEBUSY
                msg = "DDE busy"
            Case SE_ERR_NOASSOC
                msg = "No association for file extension"
            Case ERROR_BAD_FORMAT
                msg = "Invalid EXE file or error in EXE image"
            Case Else
                msg = "Unknown error"
        End Select
    '    MsgBox msg
    End If
    End Sub
    
    Private Function StartDoc(psDocName As String) As Long
    Dim Scr_hDC As Long
    Scr_hDC = GetDesktopWindow()
    StartDoc = ShellExecute(Scr_hDC, "Open", psDocName, "", "C:\", SW_SHOWNORMAL)
    End Function
