I am trying to connect Visual Basic to MS Access using ADODB. But as I execute my code, it prompts: "Provider cannot be found.It may not be installed properly." But when I check on my directory I've got my "msjetoledb40.dll" installed.
Here is my code:
Dim conn As ADODB.Connection, rec As ADODB.Recordset
Sub sample()
Set conn = New ADODB.Connection
conn.Open ("Provider=Microsoft.Jet.OLEDB 4.0;Data Source=C:\sample.mdb;Persist Security Info=false;")
End Sub
This would be better:
Sub sample()
Dim conn As ADODB.Connection, rec As ADODB.Recordset
Set conn = New ADODB.Connection
conn.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=C:\sample.mdb;"
conn.Open
End Sub
You missed a point.
Microsoft.Jet.OLEDB 4.0 => Microsoft.Jet.OLEDB.4.0
Ref: http://www.connectionstrings.com/.
Confirming the version of your MS Office on which the script is running. If you have installed MS Office 2013 or later, you should revise the connection string from:
Provider=Microsoft.Jet.OLEDB 4.0;Data Source=C:\sample.mdb;Persist Security Info=false;
to:
Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\sample.mdb;Persist Security Info=false;
At least, this sovled my problem.
My solution:
Error 3706
cs = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & sPath & ";Persist Security Info=False;"
Just Change 12.0 for 15.0
cs = "Provider=Microsoft.ACE.OLEDB.15.0;Data Source=" & sPath & ";Persist Security Info=False;"
and works, always you must to try change the version of the controller!.

There is an excel macro which uses oledb 12.0, worked fine but now some users experiencing issues. It turned out they don't have version 12.0 anymore, only 16.0. Upon changing the code from 12.0 to 16.0 there is a new error message popping up: "Could not find installable ISAM"
This is the original piece of code:
Dim connection As Object 'New ADODB.connection
Dim rs As Object 'New ADODB.Recordset
Dim query As String '
Dim where_filter As String
Dim counter As Integer
Set connection = CreateObject("ADODB.Connection")
Set rs = CreateObject("ADODB.RecordSet")
connection.Open "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & fullpath & _
";Extended Properties=""Excel 12.0;HDR=Yes;"";"
query = "SELECT * FROM [Sheet1$]"
Upon changing to:
connection.Open "Provider=Microsoft.ACE.OLEDB.16.0;Data Source=" & fullpath & _
";Extended Properties=""Excel 16.0;HDR=Yes;"";"
we face the "could not find installable isam" error message.
For the users who has version 12.0 the original code works and the connection string at the locals looks like this:
ConnectionString : "Provider=Microsoft.ACE.OLEDB.12.0;User ID=Admin;Data Source=C:\Folder\excelfile.xlsx;Mode=Share Deny None;Jet OLEDB:System database="""
But for the users who have only 16.0 the revised code gives the following connection string at the Locals:
ConnectionString : "Provider=Microsoft.ACE.OLEDB.16.0;Data Source=C:\Folder\excelfile.xlsx;" : String
How I should revise the code to work with version 16?
Thank you!
This is my first question so constructive criticism is welcome! I am attempting to query an access database from excel vba and place the return information into an Excel range. I get this error:
Error Message: "Run-time error '3709' The connection cannot be used to
perform this operation. It is either closed or invalid in this
context."
Code:
Sub Importfromaccess()
Path = "C:\Users\myUser\Desktop\Database1.accdb"
Set cn = CreateObject("ADODB.connection")
cn.Open "Provider=Microsoft.ACE.OLEDB.12.0; Data Source=" & Path & ";"
Set rs1 = CreateObject("ADODB.recordset")
rs1.activeconnection = cn
Dim strSQL As New ADODB.Command
strSQL.CommandText = "SELECT * FROM Tooling WHERE TID=BD0001"
strSQL.CommandType = adCmdText
Set rs1 = strSQL.Execute ' This is the line the error occurs on
Sheets("Calc").Range("K1").CopyFromRecordset rs1
End Sub
I have enabled the following references:
Visual Basic For Applications,
Microsoft Excel 16.0 Object Library,
OLE Automation,
Microsoft Office 16.0 Object Library,
Microsoft Access 16.0 Object Library,
Microsoft ActiveX Data Objects 2.0 Library,
I tried placing the line:
cn.Open "Provider=Microsoft.ACE.OLEDB.12.0; Data Source=" & Path & ";"
right before the error line and received this error:
Run-time error '3705': Operation is not allowed when the object is
open.
Anybody know what my problem might be?
First (and unrelated to your error), unless you need to support clients using Windows 2000 or earlier, you should reference the highest Microsoft ActiveX Data Objects version instead of 2.0. If you're only using ADODB to interact with the database, you don't need the Microsoft Access 16.0 Object Library at all.
Second, if you already have a reference, don't create late bound objects like this:
Set cn = CreateObject("ADODB.connection")
Adding the reference early binds the type, so explicitly declare them and instantiate them using New:
Dim cn As ADODB.Connection
Set cn = New ADODB.Connection
Your connection string should be fine - where you run into problems are these 2 lines:
Set rs1 = CreateObject("ADODB.recordset")
rs1.activeconnection = cn
Executing an ADODB.Command will return the Recordset, not the other way around. Remove those 2 lines entirely. Instead of attaching the connection to the Recordset, you need to use it when you're building your ADODB.Command:
Dim strSQL As New ADODB.Command
strSQL.ActiveConnection = cn '<---Insert this.
strSQL.CommandText = "SELECT * FROM Table1"
strSQL.CommandType = adCmdText
Also, get rid of the Hungarian notation there - it's confusing as hell. An ADODB command isn't a String, so why should it be named strFoo?
You also need to clean up after yourself - don't leave your recordset and connection just hanging open when you're done with them. Call .Close when you're finished.
Finally, your SQL statement is most likely incorrect - you probably need to enclose your TID in single quotes('):
"SELECT * FROM Tooling WHERE TID='BD0001'"
It should look closer to this:
Sub Importfromaccess()
Dim Path As String
Path = "C:\Users\myUser\Desktop\Database1.accdb"
Dim cn As ADODB.Connection
Set cn = New ADODB.Connection
cn.Open "Provider=Microsoft.ACE.OLEDB.12.0; Data Source=" & Path & ";"
Dim query As New ADODB.Command
query.ActiveConnection = cn
query.CommandText = "SELECT * FROM Tooling WHERE TID='BD0001'"
query.CommandType = adCmdText
Dim rs1 As ADODB.Recordset
Set rs1 = query.Execute ' This is the line the error occurs on
Sheets("Calc").Range("K1").CopyFromRecordset rs1
'CLEAN UP AFTER YOURSELF:
rs1.Close
cn.Close
End Sub
You already Set rs1
How about trying something more like:
Sub Importfromaccess()
Dim strSQL As String, strPath as String
Dim cn as Object, rs1 as Object
strPath = "C:\Users\myUser\Desktop\Database1.accdb"
Set cn = CreateObject("ADODB.connection")
cn.Open "Provider=Microsoft.ACE.OLEDB.12.0; Data Source=" & Path & ";"
Set rs1 = CreateObject("ADODB.Recordset")
strSQL = "SELECT * FROM Tooling WHERE TID='BD0001'"
rs1.Open strSQL, cn
Sheets("Calc").Range("K1").CopyFromRecordset rs1
End Sub
After some thorough rearranging I think I figured it out. I'm surprised at what changes fixed the problem but the following code works:
Dim con As New ADODB.Connection
Dim rs As ADODB.Recordset
Dim cmd As New ADODB.Command
cmd.CommandText = "SELECT * FROM Tooling WHERE TID='BD0001'"
con.Open "Provider=Microsoft.ACE.OLEDB.12.0; Data Source=C:\Users\myUser\Desktop\Database1.accdb;"
cmd.ActiveConnection = con
Set rs = cmd.Execute
Sheets("Calc").Range("K1").CopyFromRecordset rs
rs.Close
con.Close
The final error was fixed with:
cmd.CommandText = "SELECT * FROM Tooling WHERE TID='BD0001'"
this line previously did not include single quotes around BD0001.
I also added an ActiveConnection to the Command object.
Edit: This is the simplest working version of this I could manage courtesy of all you helpful people!
While opening database connection I get an error
User defined type not defined
I am able to create connection in same macro, but I have to create function for connection to use any were in project.
Option Explicit
Public CN As ADODB.Connection
Public Function Connection() As ADODB.Connection
If CN Is Nothing Then
Set CN = New ADODB.Connection
Dim Con_str As String
Con_str = "Provider=SQLOLEDB;Persist Security Info=True;User ID=" & getvalue("User_id") & _
";Password=" & getvalue("Password") & _
";Initial Catalog=" & getvalue("Database_Name") & _
";Data Source=" & getvalue("Server_Name") & ";"
Debug.Print Con_str
CN.Open Con_str
End
Set Connection = CN
End Function
Sub teting()
Dim rs As ADODB.Recordset
rs.Open connetion(), adOpenStatic 'CreateObject("ADODB.Connection")
ActiveSheet.range("A10").CopyFromRecordset rs
End Sub
What is the actual cause of this issue?
Thanks,

You need to enable Microsoft ActiveX Data Objects x.x Library, where x.x is replaced by the version number that you have available.
You'll find it under tools --> references in the VBA editor.
I intended to write a macro to query both csv and xml files using Access vba. I do not want to parse csv or xml to a temp table in Access.
Dim dbConnection As ADODB.Connection
Dim rs As ADODB.Recordset
Dim dbConnectionString As String
dbConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & _
sourcefilepath & ";Extended Properties=""csv;HDR=Yes;FMT=Delimited"""
Set dbConnection = New ADODB.Connection
dbConnection.Open dbConnectionString
Set rs = New ADODB.Recordset
strSQL = "SELECT * FROM " & sourceFileName
rs.Open strSQL, dbConnection, 3, 3
rs.Close
dbConnection.Close
I tried the code above and kept getting "could not find installable ISAM" error message.
I also tried:
dbConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" & _
sourcefilefolder & ";Extended Properties=""txt;HDR=Yes;FMT=Delimited"""
It didn't work, either.
Any advice would be appreciated. Thanks in advance.
Click on Tools > References and scroll down to:
Microsoft ? (The question is to select which connection you decide to use.)
And select:
Microsoft ADO (version you want)
and
Microsoft OLE (version you want)
I have found it also helps to select: Microsoft DAO Jet 3.6 even when I don't plan to use it as it supports several older utilties I often call on.
I get a "User-defined type not defined" error when I execute the below code, and the
"objCon As ADODB.Connection"
is highlighted on the first line.
I am trying to set a connection from Excel to Access via VBA code. Thank you for any advice!
Private objCon As ADODB.Connection
Private rstRec As ADODB.Recordset
Private strQry
Sub Connect()
Dim strConn As String
Set objCon = New ADODB.Connection
objCon.Mode = adModeReadWrite
If objCon.State = adStateClosed Then
strConn = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & "C:\DB\Db.accdb;Persist Security Info=False;"
objCon.ConnectionString = strConn
objCon.Open
End If
End Sub
You can do one of the following
set objCon = CreateObject("ADODB.Connection")
set rstRec = CreateObject("ADODB.Recordset")
Or in VBA Editor
