I am doing a visual basic applications that is point of sale. It runs off a Access database to do the inserting
Every time my program compiles, it wipes my Inventory Database clean. What is wrong?

Private Sub buttonadd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles buttonadd.Click
        Dim connectionString As String = _
       "Provider=Microsoft.Jet.OLEDB.4.0;" & _
       "Data Source=" & Application.StartupPath & "\Inventory.mdb;" & _
       "User ID=Admin;" & _
       "Password="

        Dim logInOleDbConnection As New OleDbConnection(connectionString)

        ' Create a ADO.NET OleDbCommand.


        Dim sqlInventoryString As String = "INSERT INTO Inventory ([First Name],[Last Name],[Description],[Order Placed],[Order Shipped],[Order Recived],[Comments],[Shipping])  values('" & txtfirstname.Text & "','" & txtlastname.Text & "','" & txtdescription.Text & "', " & checkboxorderplaced.Checked & "," & checkboxordershipped.Checked & "," & checkboxorderreceived.Checked & ",'" & richtxtcomments.Text & "');"
        Dim sqlCommand As New OleDb.OleDbCommand(sqlInventoryString, logInOleDbConnection)
        ' Open the database connection.

        logInOleDbConnection.Open()

        ' Run the sqlCommand.
        Dim countFound As Integer = CType(sqlCommand.ExecuteScalar, Integer)

        ' Close the database connection.

        logInOleDbConnection.Close()

        ' If countFound = 1 a record with a matching UserName and Password
        ' was found..

        If countFound = 1 Then
            Label13.Text = "Insert Unsuccessful please try again"
        Else

            Label13.Text = "Insert Successful"
            txtfirstname.Clear()
            txtlastname.Clear()
            txtdescription.Clear()
            richtxtcomments.Clear()


        End If

Hi

>Every time it COMPILES it wipes the database clean????

As dqmq asked, are you sure? I would think its more likely that the database could be wiped clean if you are reinstalling a new version every time. If your setup program has a clean version of the database that usually gets installed with the software and you are running this setup program, it could overwrite your existing database.

i am sorry i guess i did not make my question clear. Their is an existing access database (Inventory.mdb)each time i run my point of sell software the existing entries that are in the Inventory.mdb (YES i checked to see if they actualy got inserted) from the previous time I ran the program are missing. I hope that made a little more sense. Its not litterly wiping my access program just the entries in the database
