Why do people ask this day after day ? How does anyone think it's remotely possible ?

Becaus every secure system (eg, banking websites) log you out if you try to click back.

Obviously this is a much more indepth system than just "avoid user clicking back button", and requires much more work than a simple javascript hack.

Yeah, these folks all ask the wrong question, that's the core problem

Offcourse ..It is a bit of difficult code...than just javascript code
...but We need that code..Can anyone help us?

try putting this in your code

<Script Language="javascript" runat="server">

javascript:window.history.forward(1);

</Script>

That is close to useless.

How come?

*sigh* It's really very trivial. You CANNOT stop the back button. You CAN make every page check if a session variable is set, and if not, redirect to your login page. I use a base class for this.

Hi,

Instead of doing a redirect to next page
do a javascript location.href='next_page'

$herin Iranimose

In the database , i have a varchar type field , it's length is 8000.
i am adding one parameter from the code behind.It's type is string and the length is 5645.
After the execution of insert query in the database , it gives the error

Implicit conversion from data type ntext to varchar is not allowed. Use the CONVERT function to run this query.

If you have an apple & I have an apple and we exchange our apples, then each of us will still have only one apple but if you have an idea & I have an idea and we exchange our ideas, then each of us will have two ideas!

Check that the parameter is

parametername.Parameters.Add(new SqlParameter("@fieldname", SqlDbType.VarChar));
parametername.Parameters["@fieldname"].Value = textbox.Text;

not

parametername.Parameters.Add(new SqlParameter("@fieldname", SqlDbType.Text));
parametername.Parameters["@fieldname"].Value = textbox.NText;

i am using dbtype , and varchar is not available in dbtype.

If you have an apple & I have an apple and we exchange our apples, then each of us will still have only one apple but if you have an idea & I have an idea and we exchange our ideas, then each of us will have two ideas!

try Varnumeric

On my vb.net page has following controls
for example:

Label1

dropdowncontrol1

dropdowncontrol2

link1

i am using flyout on link1 click

<cc1:flyout id="Flyout1" runat="server" attachto="link1">

content..

<cc1:flyout>

so whenever flyout is opened , it will display content of flyout as well as from background dropdowncontrol1 and dropdowncontrol2 also seen in that opened flyout.

So How can i disply only flyout content not that dropdownlist controls?

Well, it's clear to me now that your flyout is a third party user control. Doesn't that mean you should ask the vendor ?

Some controls just appear behind drop boxes. That's because of how they are written. I'm not sure of the details, but if your control shows up that way, you need to find another.

I answered his question below and then he deleted the opening post!! Mad | :mad:

You're right, I noticed that. I dunno why he deleted it, and then reposted, but at least he finally posted some code ( he previously posted in the C# forum before I pointed him here ).
