My ASP label not displaying
Hello,
Please have a look at my VB/ASP code and tell me if you can see what's wrong (I have bolded the important segments):
Code:
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01//EN"
"http://www.w3.org/TR/html4/strict.dtd">
<%@Page Explicit="true" Language="VB" Debug="true"

<html>
<head>
<title>Autobody</title>
</head>
<script runat="server">
Dim Connection As MySqlConnection
Dim MDA As MySqlDataAdapter
Dim DS As DataSet
Sub Page_Load(sender As Object, e As EventArgs)
username_textbox.Text = String.Empty
password_textbox.Text = String.Empty
feedback_label.Text = "feedback"
End Sub
Function Connect() As String
Dim ConStr As String = "server=localhost; user id=gib;
password=gibpw; database=autobody;"
Connection = New MySqlConnection(ConStr)
MDA = new MySqlDataAdapter()
DS = new DataSet()
Connection.open()
Return "OK"
End Function
Function Disconnect() As String
Connection.close()
Return "OK"
End Function
Sub SubmitButton_Clicked(Sender As Object, E As EventArgs)
If Not (Connect() = "OK") Then
feedback_label.Text = "Error connecting"
Return
End If
FillDataSet()
If Not (Disconnect() = "OK") Then
feedback_label.Text = "Error disconnecting"
Return
End If
Authenticate()
End Sub
Sub FillDataSet()
Dim Command As New MySqlCommand
Dim Query As String
Query = "SELECT * FROM CLIENTS;"
Command.Connection = Connection
Command.CommandText = Query
MDA.SelectCommand = Command
MDA.Fill(DS)
MDA.dispose()
Command.dispose()
End Sub
Sub Authenticate()
Dim username As String
Dim password As String
Dim i As Integer
For i = DS.Tables(0).Rows.Count-1 to 0 Step -1
username = DS.Tables(0).Rows(i).Item("username")
If username = username_textbox.Text.Trim() Then
password =
DS.Tables(0).Rows(i).Item("password")
If password = password_textbox.Text Then
Response.Redirect("access_granted.html")
Else Exit For
End If
End If
Next
feedback_label.Text = "Access denied"
End Sub
</script>
<body>
<form runat="server">
<table cellpadding=0 cellspacing=0 border=1>

<tr>

<td style="width: 200px;"><asp:textbox style="width: 200px;"
id="username_textbox" text="" runat="server"/></td>

<tr>

<td style="width: 200px;"><asp:textbox style="width: 200px;"

runat="server"/></td>
</tr>
<tr><td colspan=2><asp:button id="login_button" text="login"
onclick="SubmitButton_Clicked" runat="server" /></td></tr>
<tr><td colspan=2><asp:label id="feedback_label" ForeColor="red"

</table>
<!-- AutoPostBack=true -->
</form>
</body>
</html>
Basically, I'm trying to get the Page_Load subroutine to execute on the page load, but it doesn't seem to be called. I'm assuming that because I set my feedback label to "feedback" in the Page_Load subroutine, I should see it displayed on the page saying "feedback" on first loading the page and every time I refresh. But this doesn't happen. I'm lead to conclude that the Page_Load subroutine is not being called on the page load.
Can anyone tell why?
