Hi,

I have a table with an attchment and made a form to visualise it. Now I would like to open it as if I double clicked it and pressed open but with a macro on the click event? Any idea how to do that? (It is a Microsoft PowerBI desktop file)

Hi. Welcome to AWF!

Not sure if this is the best approach, but one way is to save the attachment to the disk and then open it from there.

Save, or open an attachment that's in a table? I think the latter?
See if this helps (specifically the Display Functionality). You might decide it's easier to just go with the Access dialog.

In the database a devlopper stored an excel as an attachment in a single record table. It is being used to export data for the user and what is perfect is that the user can mess with the exported file, the next user who will want to export will have something working from the orginial "template". My issue if I give a link to a stored pbix is that there is no way to make it read-only (if somebody delete something, it is not working for the next one) so I would prefer the user to open a stored template by clicking a button if possible. My issue with the dialog, user can delete it, save another one, etc....and it is quite heavy to click, to open a window to select a file and click open.

Then you probably want to look into saving it to disk, then opening it from there (a copy)

Disk solution is bad in my case, I would need to overwrite the copy that has to be accessible to an entire corporation with a master each time someone uses it (don't know how to that either)...and worst of all it can't be used by multiple people at the same time. Isn't there a way to easily open an attachment? If we ask a user to attach a contract or an invoice, can't we get other users to just open them by clicking a button without giving them the opportunity to modify, delete or overwrite the attachment?

I guess I'm confused. I thought what you WANTED was to have them mess with a copy, not the original.
I'm pretty sure you won't be successful having "multiple people" editing an Access table attachment at the same time ... (why would you want that?)

The idea is to have a master file in the database (a report). When a user click a button, he opens the file but he can't save it back in the database...therefore the original file is still in the database, user has a temporary file that he can save on his hard disk if he wants to. When next user opens the file from the database on his computer, same thing, they have no way to overwrite the attachment (especially if they got the file through a button). As an example this how to open an excel an excel file stored in an attachment and whatever the user do then with the file in excel, it won't affect next one
Code:
Dim strFileName                 As String
    Dim xlApp                       As Object
    Dim xlWkBook                    As Object
    Dim xlWkSheet                   As Object
    Dim strID                       As String
    Dim qry                         As DAO.QueryDef
    Dim rec                         As DAO.Recordset
    Dim fField                      As DAO.Field
    Dim j                           As Long
    
    strID = Nz(Me!pr_ID, -1)
    If strID = -1 Then Exit Sub
    
    strFileName = Environ("USERPROFILE") & "\" & Format(Now, "yymmddhhnnss") & " - Planning.xlsm"
    'MsgBox strFileName & vbCrLf & ExistFile(Environ("USERPROFILE") & "\", , , False)
    If bSavePJ(strFileName, "1") Then
            
        Set xlApp = Nothing
        On Error Resume Next
        Set xlApp = GetObject(, "Excel.Application")
        On Error GoTo 0
        
        If xlApp Is Nothing Then Set xlApp = CreateObject("Excel.Application")
        
        If xlApp Is Nothing = False Then
        
            xlApp.Visible = True
            
            Set xlWkBook = xlApp.workbooks.Open(strFileName)

Hi. I could be off, but I thought that's what I suggested earlier. The user clicks a button, you save a copy of the attachment on their computer and then open it. That keeps the original attachment untouched. No?

Sorry I did not understand "programatically"...I thought you meant I had to take the file and copy the file on their laptops. So if I have an attachment in table 'T_Reporting' as first and only record called 'Report.pbix', how can I get the user an dialogbox to save it where he wants?

Alright...then it's like I already said ... Save a copy to disk, and open the copy for them...

I try but I can't get the dialog box to open for a user nor the file to be saved if I try to save it on my disk. Can you spot anything wrong? (Note that there is only one record, I loop only because I don't know how to go to the first record)
Code:
Private Sub BI_Attachment_Click()
Dim dbs As DAO.Database
Dim rst As DAO.Recordset2
Dim rsA As DAO.Recordset2
Dim fld As DAO.Field2
Dim strFullPath As String
'Dim fpath As String
        'Get the database, recordset, and attachment field
        Set dbs = CurrentDb
        Set rst = dbs.OpenRecordset("T_Reporting")
        Set fld = rst("BI_Attachment")
       
        'Get the recordset for the Attachments field
         Set rsA = fld.Value
       
        'Navigate through the table
        Do While Not rst.EOF
       
'Let user chose path

fpath = Application.FileDialog(msoFileDialogFolderPicker)
         
  strFullPath = fpath & "\Reporting PMO.pbix"

'Save file
rsA("Reporting PMO.pbix").SaveToFile strFullPath
Loop
'Open the file

End Sub

Hi. You can use the FileDialog object for that. However, I wonder why you would care where the user wants to store the file, or even let them. If you were to allow users to double click on the attachment to open it normally, users won't need to select a location where to save it (hint, Access saves it in a default location). So, you can also give them the same experience. When they click on your button, simply save the file "somewhere," they don't need to know where it is. In fact, you may have to delete it anyway afterwards to avoid any potential copy conflicts.

Well, I for one thought the idea was to store a "master" in the table and force users to save any changes to it wherever they wanted if they chose to do so. This means no file dialog code is really needed when you have the Save As feature in the native application. I figured the link I provided would be OK for that but I guess not - and only 19 lines of code.

Hi. That's a nice approach. But if the Attachment Control is locked, how did you save the attachment in the first place?

Hi,

Thanks to all for your help. I opted for the save a copy as where the user wanted, that allows him to set filters for his department in the file without having to go through Access and having to set them back every time.
