Each site is different. You can automate some operations on your site, and do comparisons with the debug and release builds.
|
|
|
|
|
The Debug code give ideas as the site behaves... making easy the hacker work.
On performance issue, Debug code, the asp.net engine must to check the error, face the error against the asp.net error code table, and write a possible solution.
Release code just write a default error page. the second is fastest solution, but, its irrelevant over small sites.

Hi,
I am trying to abandon the session which started at Login. When I click on Logout, I am redirected to the Login page, which is fine. The problem is, I can still type in the page address that I want in the address bar OR I can click "Back" on the browser and the pages of the site will load without authentication.
What am I doing wrong? Heres the code I have used:
FRONT END<br />
<br />
<pre><'asp:HyperLink runat="server" cssclass="STlvl2" navigateurl="?Logout=1" id="hlLogout">Logout/></pre><br />
CODE BEHIND<br />
<br />
<pre>If Request.QueryString("Logout") = "1" Then
Session.Abandon()
Response.Redirect("../frmLogin.aspx")
End If</pre><br />
<br />
<br />

It may have been a typo, but why is there a ' in the hyperlink?
Also, why do you have a hyperlink that closes the session. Why not abandon the session in the button click event?
|
|
|
|
|
The ' in the hyperlink is so that the code is displayed on this page lol..
I dont actually have ' in my source code.
Secondly, I think I will try to abandon the session by using the btn.click event as you said through a link button. Maybe that will work.
Thanks for the idea mate.

Hello,
I am calling page2.aspx from Hyperlink field in Grid in page1.aspx and I pass to Page2.aspx 2 parameters. I would like to hide those parameters from the user.
I mean instead of http://MySite.com/page2.aspx?Param1=0&Param2=1
I would like to get http://MySite.com/page2.aspx and also send those 2 parameters to page2.aspx.
I know how to do it if it was not an hyperlink from a grid:
server.transfer "page2.aspx?Param1=0&Param2=1" and it works fine
Thanx

Why not use session vars?
you can also change the hyperlinks to link buttons, then do your server.transfer there.
|
|
|
|
|
The true is that I pass ~20 parameters and I don't think that is a good idea to pass them through session vars.
You suggest to use the linkbutton.
Let me explain and simplify my problem,
I have a gridView with 2 columns: First column is an hyperlink of "item name" and the second column is the string containing "URL" for the first column. The second column is visible=false
The problem is that the URL string is very long and contain ~20 parameters. So when the user click on the link, we can see on the URL a long string, I would like to get the same action than I call to server.transfer.
Perhaps, you have got another idea.
Thanx

You can try something like this:
protected void GridView1_RowCreated(object sender, System.Web.UI.WebControls.GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.Footer)
{
LinkButton lnkbtn = new LinkButton();
lnkbtn.Text = "Add New";
lnkbtn.CommandName = "Add";
e.Row.Cells(0).Controls.Add(lnkbtn);
}
}
and on the aspx page change the gridview declaration to:
< asp:gridview id="GridView1" runat="server" onrowcreated="GridView1_RowCreated" >
</ asp:gridview >
|
|
|
|
|
Thanx I will try this

Sounds like a create permission problem on the server (if server is Win 2003 the user is NETWORK SERVICE by default). You also may want to set it to create one level down from you website's root. Something like "mywebsite/uploads" or something like that.
Right-click a folder where you want the account to have write permission, choose "Properties" and then Security tab, add the account into user account list, and then set proper permissions to the account.
You may also want to look at impersonation.

could i ask you why you do not want to use a session variable ??

When you get mad...THINK twice that the only advice

because many things are related together, if u have read the details you would know ...
In other scenarios i might 
first, it's not in one form, it's 2 forms parent and pop up
second, i want to access if from javascript
third, to get highest performance u need to reduce the sessions in ur app
hope u got me
Best Regards

can u reach the variable from both forms??!
and if u think like this, 2 variable * 1,000 user = 2,000 session opened with the server, that would exhaust the server
so what about 10,000 user
what would happen?
anyway, i implemented it by myself without using sessions
if u need the code tell
Best Regards

Put the values in an array and assign the array to window.returnValue, then close the window. The array becomes the return value of the showModalDialog call.
