My connection String in a separate class called(Classes.vb)

'for my pc
Public cs As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=\\KMA18214\Share\Stock.accdb;Persist Security Info=True;jet oledb:database password=*******"

'Public cs As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=\\KMA18214\Share\Stock.accdb;jet oledb:database password=*****"

'For build the project on client pc
'Public cs As String = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=\\192.168.1.5\Share\Stock.accdb;jet oledb:database password=*****"

End Module

I think the Connection String makes this error message occurs but my Application is already running well all the time , But suddenly this message appears i don't know why ?

any suggestions

Thanks in advance ..........................
