AJAX Timer causes javascript error on page

I have an AJAX asp:Timer that when added to my LogView.aspx page causes a javascript error in the browser:

Expected ';'

Default.aspx Line: 963
Code Blush | :O

First, the page that is being displayed in LogView.aspx and not Default.aspx. Also there is no javascript on my LogView.aspx page:

<form id="form1" runat="server">

<asp:ScriptManager ...>
</asp:ScriptManager>
<asp:UpdatePanel ID="UpdatePanel1" runat="server">
<ContentTemplate>
<asp:Timer ID="Timer1" runat="server" Interval="10000" OnTick="Timer1_Tick" />
<asp:TextBox ID="TextBox1" runat="server" Text="" />
</ContentTemplate>
</asp:UpdatePanel>

The code behind is:

protected void Timer1_Tick(object sender, EventArg e)
{

TextBox1.Text = "Hello";

}

Also, when run the Timer event is never called. I did a view source and the error line shows where the onLoad () System.Application.add.init(function () {$create(Sys.UI._Timer, ...

This is confusing. Any Ideas?

Thanks,

Steve Holdorf

Try using proper closing tags instead of using /> on a single tag.

What language is the ASP page coded with, C#?

I just wonder what's being sent to the browser, like an erroneous block of C#.

It is writen in C#. When the ajax timer is removed from the page no javascript errors occur. The timer event is correct and on compile no build errors.

I am posting this after 100 hours research and no solution.

I have this application written in vb.net / asp.net / Ext.net / ms sql 2008

It was working fine so far, recently i have decided to upgrade my VS to to VS 2012 ( What a mistake...) I installed it and run my application i have started to getting below error message

"
Attempted to read or write protected memory. This is often an indication that other memory is corrupt. "

I have uninstalled everything that comes with VS2012 but still no luck same error....
When i chase this error i saw that i am getting the exception at where i open my connection to my ms sql 2008 database. Here is my connection class

Does that comma between the ip address & port number exist in your code, or is it just a typo when you created the message?

It should be a colon :

embed logo image in email

I am sending emails as HTML using MailMessage in C# and I am showing my website logo at the top of the email message. Currently I am showing my logo as but as you know using such way it will not show the logo when the user is not connected to internet and in addition, most of web based as well as email clients will prompt the user to show or not show the image.

Is there any way, to embed the image in my email so it will force showing it?

You can embed your images to the email.

Example:
Let say you want Image1.jpg to show in you email

Attached the Image1.jpg to you email and your img tag will look as follows:

HTML

<img src="cid:Image1.jpg" width="100" height="100" />

it is better to host your images than embedding it, last time I checked, gmail does not embed the images but it has been a while when I used this way, just test it in web mail clients.

Hi all
I have problem with respons.redirect()?????
I have wrote a website with Asp for authentication users,
in login.aspx file I have wrote a script code witch authenticate user.
I want to load another file after successfull login.
this is my code in login.aspx file:

 btnLogin_Click(object sender AuthenticateEventArgs e)
    {
        Boolean blnresult;
        blnresult = false;

   blnresult = Authentication(Login1.UserName, Login1.Password);
        if (blnresult == true)
        {
 // This is the actual statement which will authenticate the user
    Response.Redirect("~/Welcom.aspx",false);
            Context.ApplicationInstance.CompleteRequest();
            e.Authenticated = true;}

<asp:content ID="Content1" ContentPlaceHolderID="ContentPlaceHolder1" Runat="server">
    <asp:Login ID="Login1" runat="server"   >
</asp:Login>
</asp:content>

but after login the Welcom page doesnt load!!!!
what do you think about this?
why it doesnt work?

If the redirection is to another script on the same server, use Server.Transfer instead.

The code lines following the redirect/transfer don't get executed. Swap around.

Your comment // This is the actual statement which will authenticate the user, is in the wrong place

the line

blnresult = Authentication(Login1.UserName, Login1.Password)

does the authentication, and is very likely that function is where your problem is.

Use Response.Write to find out what blnresult state is after Authentication.

You seem to be confusing the table name (Authenticate) in the database as a function. You need to create a function that will query the database for name and password, returning true/false. (your previous code is expecting a True/False reply from a function named Authenticate)

First, test your redirection works, by creating an empty Authenticate function, returning True. Then you can move on and tackle the database/authentication stuff. Probably best if you post in the database forum for SQL related help.
