ASP.NET Need Help With WEB MATRIX Insert

P

Polyhedron_12

I am having problems calling functions in general in VB. I keep
getting alot of errors. Can anybody help me out with this? I put the
error message on the same line that it says it is at. I believe that I
am not calling the function correctly.

The MyInsertMethod function is the function that comes in the Web
Matrix Toolbox


<%@ Page Language="VB" %>
<script runat="server">

' Insert page code here


Function MyInsertMethod(ByVal tier1Name As String) As Integer
Dim connectionString As String = "server='(local)'; user
id='sa'; password='ladiedah'; database='accessory'"
Dim dbConnection As System.Data.IDbConnection = New
System.Data.SqlClient.SqlConnection(connectionString)

Dim queryString As String = "INSERT INTO [Tier1]
([tier1Name]) VALUES (@tier1Name)"
Dim dbCommand As System.Data.IDbCommand = New
System.Data.SqlClient.SqlCommand
dbCommand.CommandText = queryString
dbCommand.Connection = dbConnection

Dim dbParam_tier1Name As System.Data.IDataParameter = New
System.Data.SqlClient.SqlParameter
dbParam_tier1Name.ParameterName = "@tier1Name"
dbParam_tier1Name.Value = tier1Name
dbParam_tier1Name.DbType =
System.Data.DbType.StringFixedLength
dbCommand.Parameters.Add(dbParam_tier1Name)

Dim rowsAffected As Integer = 0
dbConnection.Open
Try
rowsAffected = dbCommand.ExecuteNonQuery
Finally
dbConnection.Close
End Try

Return rowsAffected
Label1.Text = "Hello2"
End Function

Sub Page_Load
Label1.Text = "Hello"
End Sub

Matt,
The following sample is a good source of
understanding functionality of event handling on the buttons in web form.
