I want to open and work (read only) with an Access database from another computer. How can I do this?
You have a number of options depending on how you want to handle it.
1. you can open the database in access and then save a table or query as a spreadsheet
2. In Excel use Data ... Get External Data .. New Database Query ... Microft Access database. If you use the record new macro feature this will give you enough to understand most of the VBA.
3. You can create a reference (in VBA tools ... references) to either a DAO or ActiveX Data Object library which will then give you access to the programming objects to open and select data. A useful method in this is the "copyfromrecordset" method. You may get more help on this from an Access site than from this Excel site
Hope this points you in the right direction. When you know which you want to do then update this and I will find some code.

I need to use the third option. Can you give me some code example?
This code opens the database gets the data and pastes it onto the spreadsheet. It is referencing the Microsoft DAO 3.6 Object Library although others will work and you may prefer to use ActiveX Data Objects.
Sub a()
Dim db As DAO.Database
Dim rst As Recordset
Dim strSQL As String
Dim rng As Range
Set db = DAO.OpenDatabase("C:\_pms\dbforum.mdb")
strSQL = "select CLNAM1,CLNAM2 from _client where CLSORC<>"""";"
Set rst = db.OpenRecordset(strSQL)
Set rng = ThisWorkbook.Worksheets(1).Range("A1")
rng.CopyFromRecordset rst
Set rst = Nothing
db.Close
Set db = Nothing
MsgBox "done : " & strSQL
End Sub
Sorry forgot to add that you can use the query builder in access to model the SQL or set up queries in the access database to simplify the code
Have fun
And if BD has a password?
Set db = DAO.OpenDatabase(Name:="C:\_pms\dbforum.mdb", _
Connect:="MS Access;PWD=mypassword")
Actually I think you may need to list the other "optional" parameters as in :
Set db = DAO.OpenDatabase("C:\_pms\dbforum.mdb", false,true,"MS Access;PWD=mypassword")
Sorry havn't got time to test it. I seem to remember that the optional parameters become mandatory when using connect.
Well that's what keeps life interesting.
Before passwording the database I need to declare a function connect() that opens the database and than db will be recognized outside the function. I want to use the function in every commandbutton code or just once, when opening the workbook that contains those buttons. But I don't know exactly how to do that. Can you help me?
If the buttons are on a userform then declaring the db outside the main structure should keep the object persistant.
If the buttons are on a worksheet then when the code execution stops persistance will be lost.
There is a way to get apparant persistance and that is to declare a global class module using "as new". This means that any reference to the class module will create an instance if one does not already exist.
Then you open the database in the intiialise event and return a reference to the database object. This also gives a rather nice feature that you can close the database in the terminate event thus ensuring references to the database are tidied up in the event of unexpected code ending.
I will post some code later.
AS with all these sort of things Error handling is necessary and should be used.
PART1====================== goes in a standard module
Option Explicit
Public glb As New myGlobalsClass
==========================
PART2 ============ this can go anywhere ==========
Sub a()
Dim DB As DAO.Database
Dim rst As Recordset
Dim strSQL As String
Dim rng As Range
'Set db = DAO.OpenDatabase("C:\_pms\dbforum.mdb")
Set DB = glb.DB
strSQL = "select CLNAM1,CLNAM2 from _client where CLSORC<>"""""
Set rst = DB.OpenRecordset(strSQL)
Set rng = ThisWorkbook.Worksheets(1).Range("A1")
rng.CopyFromRecordset rst
Set rst = Nothing
''' DB.Close
''' Set DB = Nothing
MsgBox "done : " & strSQL
End Sub
PART3 ============= This as a Class module called myGlobalClass
Option Explicit
Dim DB1 As DAO.Database
Private Sub Class_Initialize()
Set DB1 = DAO.OpenDatabase("C:\_pms\dbforum.mdb")
End Sub
Public Function DB() As Database
Set DB = DB1
End Function
Private Sub Class_Terminate()
DB1.Close
Set DB1 = Nothing
End Sub
It works. Thanks a lot.
Now I will test to password the data base.
