SQL CE .ExecuteNonQuery Help

Hi All -
I am rather new to vb.net using SQL CE. This is using 3.5 framework
I am trying to use a button to insert records into a table in a SQL CE database.
rowsaffected returns a value of 1, but when I preview the data, the row is never inserted.

As I am new at this, I am pretty much lost in what needs to be changed. The sql statement I am using uses hardcoded values only because I am trying to get this to intially work. Once I can get the insert statement to work, it will use variables based on user input.

Here is my code that I am using:
-----------------------------------------------------------------------
Private Sub cmdInsert_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdInsert.Click
Dim connstr As String
Dim rowsaffected As Integer

connstr = ("Data Source =" _
+ (System.IO.Path.GetDirectoryName(System.Reflection .Assembly.GetExecutingAssembly.GetName.CodeBase) _
+ ("\jhepfner.sdf;")))

Dim myconn = New System.Data.SqlServerCe.SqlCeConnection(connstr)

Dim stringAdd As String = "Insert into t_acct_Taps (acct_num,acct_Tap_key) values (9999,4948)"
Dim objcommand As New Data.SqlServerCe.SqlCeCommand(stringAdd, myconn)

Try
objcommand.Connection.Open()
rowsaffected = (objcommand.ExecuteNonQuery())
MsgBox(rowsaffected)
objcommand.Connection.Close()
objcommand.Connection.Dispose()
objcommand = Nothing
Catch ex As Exception
MsgBox(ex.ToString)

End Try
End Sub
-----------------------------------------------------------------------
The original database that I am using is c:\jhepfner.sdf

When I run this, connstr shows:
Data Source =\Program Files\jhepfner\jhepfner.sdf;

In server explorer, it shows the connection string as:
Data Source=C:\Documents and Settings\Compaq_Owner\Local Settings\Application Data\Temporary Projects\jhepfner\jhepfner.sdf

Please help, and thank you,
Jeff
