Then you screwed it up. This always works for me.

My logout option is available in all the pages. this is a part of the banner as a user control. hence i cant place in the user control.
history.go(1);
if there is a just one Page for signout then this works. otherwise throughout the application it prevents me from going to the previous page using the back button (even though the user is not logged out).
i have even tried this using Javascript code on logout, but this doesnt work.
protected void Logout_Click(object sender, EventArgs e)
{
Session.Abandon();
string sScript = " history.go(1); ";
if (!Page.ClientScript.IsStartupScriptRegistered("privacy"))
Page.ClientScript.RegisterStartupScript(typeof(Page), "privacy", sScript);
Response.Redirect("Login.aspx");
}
Please Help !!

Why dont you try the following
Put Session.Abandon(); in the logout event <b>THEN</b>
on everypage put the following:
if (Session.Count <1)
{
response.redirect("login.aspx")
}

currently i m using asp.net with C# (.net 2005, 2.0 framework).
here i m trying to upload an excel content to my database (sql server 2000).i have achieved it. but my excel sheet (column B) consist of ID's (primary key). there may be a chance to be of, getting the same value in excel sheet (Primary key violation).
I need the help from u pals!
1. how can i intimate the user while he entering a value again in a particular column (say, column B) in excel sheet.
2. or while user trying to upload the content i want to intimate him the values repeated and delete the multipl occurances.
How to proceed this? -KARAN

1 - what do you mean ?
2 - I'm still not sure what you mean, but you can run Excel on the server and control it through C# to examine a spreadsheet and/or change it.

currently i m using asp.net with C# (.net 2005, 2.0 framework).
while i m uploading my excel sheet to sql server database, i consider the "column B" (in excel sheet) values as primary key (in database also i set the primary key constrain. Now if user enter Column B2 as "1336" and column B3 as "1336" then error will occur while uploading(Primary key violation). to avoid this i m trying to follow the below two ways....
1. To intimate the user while he entering a repeatative value in a particular column (say, column B) in excel sheet. (a prompt message should be shown to the user while he entering 1336 value in Column B2 and B3)
2. Or while user trying to upload the I like to prompt him the values repeated and also automatically delete the repeatative occurance (i.e Column B3) by my coding
How to proceed this? -KARAN

I want to generate UserID from the Website when ever new user want to create account that time user have to provide userID its own choice. 
that time userid is to check with sql database if the same userID is already exists then Website Give The choice of 3 Or 4 AutoGenerated UserId which is available.
or which is not provided yet.
so it is available...
i want to Autogenerate that userID which is made by user's other information like Fristname,Lastname,Bithdate etc....

The SQL check is obviously trivial, the main thing is to come up with algorithms such as grabbing the first letter of the first name, appending the surname, and then adding numbers if necessary to create a possible username. The string class has a substring method you can use for this, or you can use myStringt[0] to get just one character ( the first, in this case ).

If you are looking at an old page and then when you try to interact with it, it logs out, then you're looking at a cached page. You can mark your pages not to cache. If you can still interact with the page, then you need to add code to stop that happening. I typically write a base class for all my pages that checks the Session("uid") value and redirects to my login page if it tells me the user is not logged in

Hello,
I have cribbed an HttpHandler class to protect certain files on my website, very much along the lines of this article[^]...
(in fact extended to include Word docs, Zip files etc, but the essential code is the same.)
All works fine but for one thing:
If a logged-in user clicks a link to, say, a Word doc, it will open in a new window, and they can then use "File/Save As.." to download it onto their computer. That's fine. But if they right-click the link and choose "Save target as.." and try to save it like that, they will get an "Access denied" message (or "no.jpg" in the example code I linked to.)
What do I need to alter in the code to allow this, without compromising the rest of it?
Presumably, right-clicking means that context.Request.ServerVariables["HTTP_REFERER"] returns null/Nothing.... what else could I use to check for this?
thanks for any ideas..

How can i develop a product catalog that diplay a large picture of product and put the description with price under the picture? I use DataList, but the pictures don't appear. Is it true, if i use image handler, my data type for image must be in binary? My current data type for image now is varchar.
<asp:DataList
id="dlstImages"
RepeatColumns="3"
runat="server">
<ItemTemplate>
<asp:Image ID="Image1"
ImageUrl='<%# Eval("Name", "~/UploadImages/{0}") %>'
style="width:200px"
Runat="server" />
<br />
<%# Eval("Name") %>
</ItemTemplate>
</asp:DataList>

Varchar will screw up the data, I would guess. You should definitely use binary fields.
However, what you are doing here appears to be linking to an image on the server, not the image in the database; this means that the image name would be in varchar. Is your intention to refer to a folder, or to display the image data directly?
Also, you might want to use <img> tags instead of <asp:Image> controls; most people would consider it better practice to use the simplest control possible unless there's a good reason not to.

I use datatype varchar for image (put image path) and display in gridview, this is fine. But when i use the same datatype and display in datalist, the image didn't appear, but the description and price for the product appear. If i use binary for image, then i need to upload the picture to DB, rite? and also use generic handler. what is the easier way to display image for product and the details from different product categories (it's like e-commerce application)?
|

Displaying binary data directly in ASP is a bit hairy. I'd stick with an <img tag; View Source in IE to see what the path is, and check the data list to see if it's formatting your HTML as text - there should be a property in there somewhere. Again, View Source will help you out. My instinct is that it's some kind of HTML formatting issue.
