Environment is : Window 7, Visual studio 2010 Frame work 3.5, ArcObject 10.0 .net sdk.


I have used the below code in arcobject. BaseCommand implementation  (see the full code in the attached doc) to access the value from the given .accdb file. The code successfully ran and displayed the expected result, when click the command button in ArcMap  - ArcGIS Desktop 10.0. , after 10 or 20 seconds ArcMap shows the attached error message.   


Public Overrides Sub OnClick()       

Dim sAccdbPath As String = "" ' "C:\ProgramData\MapManager\Resources\Project\MapManagerProject.accdb"       

Dim pFileOpen As New System.Windows.Forms.OpenFileDialog       


If pFileOpen.ShowDialog() = Windows.Forms.DialogResult.OK Then sAccdbPath = pFileOpen.FileName       

If Not String.IsNullOrEmpty(sAccdbPath) AndAlso System.IO.File.Exists(sAccdbPath) Then           


Dim sConnString As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=" & sAccdbPath & ";Persist Security Info=False;"          

Dim sSQL As String = "" '"SELECT * FROM MgrVersion"           

sSQL = InputBox("Enter simple select query : ", "Read .accdb database")       


Using connection As New OleDb.OleDbConnection(sConnString)               

Dim pCmd As New OleDb.OleDbCommand(sSQL, connection)              

Dim pRdr As OleDb.OleDbDataReader = Nothing               



pRdr = pCmd.ExecuteReader()                   

If pRdr.HasRows Then                       



End If               

Catch ex As Exception                   


End Try           

End Using       


MsgBox("Invalid file")     


End If   

End Sub


PS: Arcobject 10.0 alos crash after connect the .accdb file using oledb connection.

what's the version of Windows 32 or 64 bit?

If you have 64bit: what's the version installed driver Access 32bit or 64bit ?

Have you compiled your dll with the ANY CPU ?

It appears that you are using pure Microsoft .NET libraries to open your OleDB connection.

Try to use the ESRI libraries and see if you still get the error. Documentation on how to use OleDB connections with ArcObjects is below:
