Do you want this to update user's copy of frontend of split database? I do it with:
Code:
If Me.tbxVersion <> Me.lblVersion.Caption Then
If DLookup("Permissions", "Users", "UserNetworkID='" & Environ("UserName") & "'") <> "admin" Then
'copy Access file
CreateObject("Scripting.FileSystemObject").CopyFile _
gstrBasePath & "Program\Install\MaterialsDatabase.accdb", "c:\", True
'allow enough time for file to completely copy before opening
Dim Start As Double
Start = Timer
While Timer < Start + 3
DoEvents
Wend
'load new version - SysCmd function gets the Access executable file path
'Shell function requires literal quote marks in the target filename string argument, hence the quadrupled quote marks
Shell SysCmd(acSysCmdAccessDir) & "MSAccess.exe " & """" & CurrentProject.FullName & """", vbNormalFocus
'close current file
DoCmd.Quit
End If
End If
This code is in Load event of form that opens on default when the db opens.
