For a client I am currently doing work for, we have a mixture of Access versions. Both versions are Access 2016, but one version is 32 bit, and the other is 64 bit (Office 365 version).
Whenever a new version of the database is released, the users can click a button to upgrade the database they are using to the most recent version.
The .accdb file is pulled down from the server and is loaded on the user’s machine, without user or admin intervention.
That’s great, empower the users.
Here is the code that works great for the 32 bit users:
'*******************************************************
'IN A BASIC MODULE:
'*******************************************************
'this is an windows api call (put PtrSafe with 64 bit versions, this works with 32 bit)
Public Declare PtrSafe Function SHFileOperation Lib "shell32.dll" _
Alias "SHFileOperationA" (lpFileOp As SHFILEOPSTRUCT) As Long
Public Type SHFILEOPSTRUCT
hWnd As Long
wFunc As Long
pFrom As String
pTo As String
fFlags As Long
fAnyOperationsAborted As Long
hNameMappings As Long
lpszProgressTitle As Long
End Type
Public Function VBCopyFolder(ByRef strSource As String, ByRef strTarget As String)
Dim op As SHFILEOPSTRUCT
Dim i As Long
With op
.wFunc = FO_COPY '(2 is the numerical value for FO_COPY)
.pTo = strTarget
.pFrom = strSource
.fFlags = False
End With
'~~> Perform operation
'success = 0
'not successful = 87
i = SHFileOperation(op)
End Function
Function FileOrDirExists(PathName As String) As Boolean
'Purpose: Function returns TRUE if the specified file
' or folder exists, false if not.
Dim intTemp As Integer
'Ignore errors to allow for error evaluation
On Error Resume Next
intTemp = GetAttr(PathName)
'Check if error exists and set response appropriately when it does
Select Case Err.Number
Case Is = 0
FileOrDirExists = True
Case Else
FileOrDirExists = False
End Select
'Resume error checking
On Error GoTo 0
End Function
'*******************************************************
'after clicking on form button:
'*******************************************************
Private Sub btnDBUpdate_Click()
Dim strSourcePath As String
Dim strDestPath As String
'network drive
strSourcePath = "R:\DatabaseFiles"
'local drive
strDestPath = "C:\DatabaseFolder"
'delete old existing database
If FileOrDirExists(strDestPath & "\Interface.accdb") Then
'if the old existing database file exists, delete it
Kill strDestPath & "\Interface.accdb"
End If
'copy newly updated database
Call VBCopyFolder(strSourcePath & "Interface.accdb", strDestPath & "\Interface.accdb")
'copy all the contents of a folder
Call VBCopyFolder(strSourcePath & "ImageFiles", strDestPath & "\ImageFiles")
End Sub
This code will show you the professional copying files image like this:
…of course it will be customized with your information.
but for 64 bit Access users …
…you will need to add some extra text to the “Long” datatypes.
THAT’S ALL YOU HAVE TO DO! (not real complex…just trying to find out the solution is a pain in the hind quarters )
Here’s the code (all the same, but change Long to LongPtr)
'*******************************************************
'IN A BASIC MODULE:
'*******************************************************
'this is an windows api call (put PtrSafe with 64 bit versions, this works with 32 bit)
Public Declare PtrSafe Function SHFileOperation Lib "shell32.dll" _
Alias "SHFileOperationA" (lpFileOp As SHFILEOPSTRUCT) As Long
Public Type SHFILEOPSTRUCT
hWnd As LongPtr
wFunc As LongPtr
pFrom As String
pTo As String
fFlags As LongPtr
fAnyOperationsAborted As LongPtr
hNameMappings As LongPtr
lpszProgressTitle As LongPtr
End Type
Public Function VBCopyFolder(ByRef strSource As String, ByRef strTarget As String)
Dim op As SHFILEOPSTRUCT
Dim i As Long
With op
.wFunc = FO_COPY '(2 is the numerical value for FO_COPY)
.pTo = strTarget
.pFrom = strSource
.fFlags = False
End With
'~~> Perform operation
'success = 0
'not successful = 87
i = SHFileOperation(op)
End Function
Function FileOrDirExists(PathName As String) As Boolean
'Purpose: Function returns TRUE if the specified file
' or folder exists, false if not.
Dim intTemp As Integer
'Ignore errors to allow for error evaluation
On Error Resume Next
intTemp = GetAttr(PathName)
'Check if error exists and set response appropriately when it does
Select Case Err.Number
Case Is = 0
FileOrDirExists = True
Case Else
FileOrDirExists = False
End Select
'Resume error checking
On Error GoTo 0
End Function
'*******************************************************
'after clicking on form button:
'*******************************************************
Private Sub btnDBUpdate_Click()
Dim strSourcePath As String
Dim strDestPath As String
'network drive
strSourcePath = "R:\DatabaseFiles"
'local drive
strDestPath = "C:\DatabaseFolder"
'delete old existing database
If FileOrDirExists(strDestPath & "\Interface.accdb") Then
'if the old existing database file exists, delete it
Kill strDestPath & "\Interface.accdb"
End If
'copy newly updated database
Call VBCopyFolder(strSourcePath & "Interface.accdb", strDestPath & "\Interface.accdb")
'copy all the contents of a folder
Call VBCopyFolder(strSourcePath & "ImageFiles", strDestPath & "\ImageFiles")
End Sub
Hope it works for you, and let me know if you have any questions.
