Hi Venkatesh and Mark,
Thanks for your help and your priceless time for me.
I just removed the code which was setting up the expiration time for the authentication cookie and it is working alright.
Previously i had code
authCookie.Expires = DateTime.MaxValue;
when creating the authentication ticket.
I removed this code and now the user session is getting logged off once the user closes the application browser window.
Thanks a lot!!

Yeah I have used frames but not in all pages... is it still possible? If so can you explain me how to do it?

While i was experimenting with code i found out that when the browser (IE) is being closed (NOT WHEN BEING REFRESHED) client screen left-top coordinate (window.screenLeft) is returned a strange 10004.
<script>
window.onunload=unloadEvent;
function unloadEvent(){
if(window.screenLeft < 10004){
}
else{
}
}
</script>
This code is tested and works fine in IE 6.0.2 as I have installed. It will fail in Mozilla/Opera (I think).

Sorry, though it sounds like an excuse I can't provide an example as it was done for a client and I don't have the rights to the code. Legalities.
However the basic are as follows. Handle the event, determine if the client is leaving your site, either via closing the broswer or navigating away, then make an out of band call (i.e. AJAX) to a method or web service on your server.

Total .NET novice here- I'm trying to determine the best way to display database content, specifically single records. Coming from an ASP/vbscript/SQL Server background, I use stored procedures for basically everything.
I experimented with the FormView and DetailsView, but they both seemed to add a lot of superfluous HTML. I then downloaded one of the sample projects (ecommerce) from the ASP.NET site which was extremely helpful - showing how database calls could be moved into public classes with values passed to variables on page load (much more familiar territory for me). I was able to modify the code to connect to my own database and display some content, but moving forward I'm curious what the best approaches are for doing this. Is there anything in the VS IDE that expedites this process, or am I going about the whole thing from the wrong perspective?
Any insights would be appreciated.
Using VS2005 / ASP 2.0 / C#, if it matters.

I'm sure you could get a lot of different opinions on this. As for me, I'm finding that I'm building data access tiers more and more, even in simple applications. I might have a class called "Product" with properties that match data fields, then a method like "GetProductById(int id)" in a data access class that returns a Product object. My .aspx page will call this data access method and work with the returned Product object, rather than directly make database calls itself.

You can use a DataSource control to bind the data to the control(s). Using a SqlDataSource you can easily configure it use a stored proc, or sql statement. Likewise, using an ObjectDataSource you can point to an object that exposes methods, such as a data access tier class.

Sounds like you need to brush up on your web design techniques.
You need to put the Page Content part of the master page in an area of the page that won't be used by the master page.
This article[^] explains how to use divs and style sheets to layout your page in a fairly standard manner. Just ensure that your page content is in the main content area, and the menu bar is in the header or sidebar areas.
Hope that helps.

I use the following code to export a page to excel. My problem is that i can't change the sheet name in excel file its always the physical name of the page not even its title!
Response.Clear();
Response.Buffer= true;
Response.ContentType = "application/vnd.ms-excel";
Response.Charset = "";
Response.AddHeader("content-disposition", "inline;filename=MyExcelFile.xls");

I'm getting the error check1 not declared. It is used as a id for my checkbox. I tried delcaring it (don't understand why I should have to), but that didn't work. Any suggestions....code below:

If you create a control in an item template, it's going to be created once per row. As such, those checkboxes can't all have the same name, and so the framework has to generate names for them. You need to handle the check changed event per row, or iterate over all the rows looking for which rows have been changed.

Hi,
As the Check box in the Item Template it is not Declared in the Page Directive.
Not only This any thing that is Nested in the ItemTemplate will not be declared.
For this you Need to Go for an Iteration through the Items.
and in the Item you Find the CheckBox using FindControl and cast the type of it as checkbox.
-- Your Code
Sub Check(ByVal sender As Object, ByVal e As EventArgs)
21
--render through items in for loop
and in loop
and cast the control using type casting to some new checkBox with name NewCheckBox so now
22 If NewCheckBox.checked Then
23 mess.Text += NewCheckBox.Text
24 End If
25
26
27 End Sub

Does anyone have any idea how to separate GUI and business/data logic by placing the GUI on a Web Server and the business/data logic on an App Server?
The only thing I can think of is to place a web service on the App Server which makes it a web server now but on the inside of a firewall and then having it make the calls to the already written DLLs, is there a better way?
-- Update - I just found out about .NET Remoting but that would not work in this case because some pieces of the overall application are VB6.
Thanks!

I think you could still use .NET Remoting, if your VB6 code was compiled as COM objects. You could write a .NET wrapper object that uses P/Invoke to execute the COM code. Then you could use .NET Remoting to communicate among the pieces.

Well in this case there are multiple web sites that interact with each other, an intranet site and an internet site. The intranet site is ASP 1.0 VB6 and the internet site is ASP.NET 2.0 VB.NET. The code that resides on the application server will be invoked by either of the web sites so Im not sure that .NET Remoting is an option in this case without doing excessive work on the VB6 site or am I wrong in assuming that?.

I do think .NET Remoting would be an option in your case. You'll want to look into COM Interop in addition to .NET Remoting; COM Interop allows your .NET code to be executed from a COM object (e.g. VB6). There's lots of articles on this - use Google to look for "COM Interop", "VB6 .NET Remoting", and the like.

Hi all.
I am wondering what you all think about this design issue. I have a page where a few things are static and one part, essentially another page, of it will be inserted when a choice is made in a combo box. The inserted portions contain static controls(text boxs, labels, drop down, etc...). I've seen this done on other websites but can't find any tutorials on how to do this. So I've thought of a couple of ways to go forward. One, I can create a user control for each inserted item, which there could be 10+ of, and register all of them on the page. Two, I can create classes which inherit from Panel for each item, programmatically add in each field into the panel at construction of the class. In either case, it could be pasted/created in when needed (on selection in the combo box).
I would prefer the user control route but I'm not sure about the impact on performance of registering 10+ controls on a page will have. The class route will be more tinkering.
I'd love to hear any kind of input on this. A link to a tutorial on how to do it would be good too.

There isn't a major performance issue with User Controls. If I understand your question, you are talking about dynamically loading UCs.

Ahh yes...it's all about the vocab. *sigh* I'll do some more searching. In fact, I already found some good things...hopefully. Thanks.
