VS 2010, VB.NET, WINFORMS. In my app i have a need to import foxpro database tables and exclude the deleted records. The problem is that FOXPRO tables keep deleted items inside the same table. I have tried using DELETED=NO in the connection string but vb throws
"Format of the initialization string does not conform to the OLE DB specification."
My function is as follows:
Dim _DBConn1 As String = "provider=vfpoledb.1; Data Source = " & file1 & ";DELETED=NO"
Dim _DBConn2 As String = "provider=vfpoledb.1; Data Source = " & file2 & ";DELETED=NO"
Dim _DBConn3 As String = "provider=vfpoledb.1; Data Source = " & file3 & ";DELETED=NO"
Dim _DBConn4 As String = "provider=vfpoledb.1; Data Source = " & file4 & ";DELETED=NO"
Using _connection As New OleDbConnection(_DBConn1)
Dim _savedId As String = String.Empty
_connection.Open()
Using _command As New OleDbCommand("SELECT * FROM " & _fileName1 & "", _connection)
Using _reader2 As OleDbDataReader = _command.ExecuteReader
While _reader2.Read
counter += 1
End While
y = 100 / counter
Dim x As String = String.Empty
End Using
Using _reader As OleDbDataReader = _command.ExecuteReader
While _reader.Read
Dim _letter As Integer = Nothing
Dim _name As String = String.Empty
Dim _content As String = String.Empty
Dim _copies As Integer = Nothing
Dim _type As Integer = Nothing
Dim _fee As Decimal = Nothing
_letter = _reader.Item(0)
_name = _reader.Item(1)
_content = _reader.Item(2)
_copies = _reader.Item(3)
_type = _reader.Item(4)
_fee = _reader.Item(5)
_UpdateLetters(_letter, _name, _content, _copies, _type, _fee)
_progress += y
Dim d As Integer = Convert.ToInt16((Convert.ToString(y).Split(".")(0)))
ProgressBar1.Increment(d)

Any ideas how my Connection string is wrong? Google results pointed me in the direction of DELETED=NO but its throwing that exception error now that I have added it..
The VfpOleDb provider excludes deleted records by default. So your connection string doesn’t need to include the deleted setting. If you wanted to include delete records… you would include “deleted=false” in the connection string.
