I am working to develop an app that will import two CSV files. During the import I need the single quotation marks removed from a couple of the fields. Then I need the data imported into a local SQLCE database. Once the user makes their changes I need to then take the two tables, group the data into three queries that then Union merge into one query that I can export as a CSV.

I have the forms completed. I need help with the easy part :) the code to make it all work.

Here is the code I currently have for importing it. It worked once, then I switched PCs and it stopped working. I get an error that too many connections are open. The code is...

Public Function SaveHoursToDB(ByVal FileName As String) As Boolean
        Dim DBName As String = "DataControl.sdf"
        'Dim password As String = ""
        Dim connectionString = String.Format("Data Source=""{0}"";", DBName)
        'connectionString = String.Format("Data Source=""{0}""; Password=’{1}’", DbName, password)
        Dim cn1 As New SqlCeConnection(connectionString)
        If Not System.IO.File.Exists(DBName) Then
            Dim eng As SqlCeEngine = New SqlCeEngine(connectionString)
            eng.CreateDatabase()
            Dim sqlString As String = "create table hours (" +
                "EmployeeID nvarchar (15) null, " +
                "Reg numeric (5,2) null, " +
                "OT numeric (5,2) null, " +
                "FromDate nvarchar (100) null, " +
                "ToDate nvarchar (100) null, " +
                "Position nvarchar(20) null) "
            Dim cmd = New SqlCeCommand(sqlString, cn1)
            cmd.ExecuteNonQuery()
        End If
        Using sr As New FileIO.TextFieldParser(FileName) With {.HasFieldsEnclosedInQuotes = True, .Delimiters = {","}}
            While Not sr.EndOfData
                Dim cmd1 As SqlCeCommand = cn1.CreateCommand()
                cmd1.CommandText = "SELECT * FROM hours"
                If cn1.State = ConnectionState.Closed Then
                    cn1.Open()
                End If
                Dim Line = sr.ReadFields()
                Dim rs As SqlCeResultSet = cmd1.ExecuteResultSet(ResultSetOptions.Updatable Or ResultSetOptions.Scrollable)
                Dim rec As SqlCeUpdatableRecord = rs.CreateRecord()
                rec.SetString(0, Line(0))
                rec.SetDecimal(1, Line(1))
                rec.SetDecimal(2, Line(2))
                rec.SetString(3, Line(3))
                rec.SetString(4, Line(4))
                rec.SetString(5, Line(5))
                rs.Insert(rec)
            End While
        End Using
        Return True
