The code behind in .NET doesn't hide anything of the html code, it only separates the html code from the server code. What's sent to the browser is still the same.
You can not hide the applet tag, as the browser has to see it, and if the browser can see it, so can anyone.
You can make it harder to spot the filename, perhaps by using Javascript to write the applet tag to the page, but then the browser needs to have Javascript enabled, or it won't work.

Hi All
I am developing an online shopping web site. The site is similar to any online shopping site where user can select categories from left menu and product will be displayed in middle of page. We had planned to display 6 products per page. As of now we are fine and clear what we need to do.
Main concern is how to bring product data. We are expecting for each category there can be 5000 products and which can grow down the year. Obviously main concern is performance as we are expecting our main users will be dial up users as site will be access from those countries where DSL in not very common. We are in discussion of our product page design and I need your advice which can help me to mitigate any post deployment risks.
I am planning,
1) On Product Page load, I will fetch all the product data (e.g. Product Name, Description, Price, ImagePath, Saleprice, special deals etc…) in DataTable say MyDataTable and cache this DataTable.
2) Now when user clicks on any category from left menus, I will create DataView from cache DataTable by filtering category and bind the DataView with my repeater control.
I believe by this approach I can gain performance hit. For our project performance hit is very critical. Please advice whether I am in correct direction or Not. Please consider this on urgent basis. Thanks in advance for your valuable reply and time

Ïf you really want to cache that amount of data, I would reccomend that you create a class for the product data instead of using a DataTable, to minimize the overhead.
In most cases I would recommend that you just fetch the data from the database, though. Caching all the data uses a lot of memory, and memory is one of the most sensetive resources of the server.
Fetching the data from the database instead of keeping it in memory also scales much better, which is important as you expect the number of products to increase. A database can easily store millions of products, much more than you can hold in memory.
I think that you should start by planning how you should display the products to the user. If you display six products per page from a category with 5000 products, there is more than 800 pages to flip through. Noone will start flipping through all those pages to find a product, so you need a better way to present them to the user.
The weaker link here is not the database, but the user. A database request can easily handle more products than any user can grasp. You just have to find the way to present the products that the user is interrested in.

Thanks for your suggestion. So as per my understanding you are suggesting that
on click of category from LHS menu, i fetch (6) products with pagination logic thru stored procedure. And on click of each pagination i fetch next 6 products and so on.
Please confirm.
Thanks

is there an equivelant to include external files in .js files similar to C/C++
#include?
thanks.

FileName.js is your javascript file within the same directory or provide a relative or absolute path as you wish.
Hope that solve your issues.

Hi.
I hope someone had similar issue and can help me.
I've created a web site and installation set up for the site. I had no problems installing it locally or on a test server but when I tired to install it on LIVE server I've noticed that my files are not installed in the \Inetpub\wwwroot even though the Control Panel->Add Remove Programs showed that the site installed and occupies ##MB. I thought this is strange.  When I found the files installed in a different directory and only because one thing. Beside Default Web Site we have VAM (Visual Asset Manager) site installed on our server, which uses port 80 as well. So every time I run install it uses VAM as a default site and installs my site under it (that's why the directory where files installed is different). I was able to work around that issue by changing VAM port to anything but 80 for a while, installing my site, and then changing VAM port back to 80.
The question is: Is there anyway I can specify in my installation to use Default Web Site instead of VAM site even though they both use port 80? 
Thank you very much.

I need to pass the ID of the control calling a function in javascript function, to the function.
I have a control ie.
where myFunction is the following function in javascript and ??? would be the command used to pass its own id.
function myFunction(controlName)
{
//I need controlName as the id of the control calling this function
//do something...
}
Regards,
Tintin

Never mind, I got it.
1.In the place off ??? you use "this". [without parentheses]
2. in function then say controlName.id [returns string]
works fine now

We use following code to show a download file dialog box:
....
Response.ContentType = cmt
Response.AddHeader "Content-Disposition", "inline; filename=" & fn & ""
Response.BinaryWrite stm.Read
Response.End
If the file name (fn) cotains non-ascii characters, the file name in the download file dialog box will contain garbage words. Actually, the variable fn's value is awalys correct when I was debugging in VS. However, once the dialog box shows, the file name turns into wrong characters.
I have tried to modify Response.ContentType, Response.CharSet and Response.Codepage, but the problem still exists.
Current ASP page file is UTF-8.
BTW, I know little about ASP or web development.
Thanks a lot.

Hi,
I want to AutoSave the Webform Fields in every 10 sec. using Ajax in .Net.
can any one help me to out of this
thanx
|
|
|
|
|
set an interval in the body onload event
setInterval('httprequest_script', 10000)
every 10 seconds the javascript httprequest_script will execute where you can send the form fields (POST or GET) to a server side script which can parse the POST or GET variables [depending on which method you use] and saves the data to a file or database.
I'm on-line therefore I am.

XMLHttpRequest can be sent asynchronously by specifying “true” for the 3rd parameter of the request open.
Request.open("POST", "testit.php", true);
The routines I use are not guaranteed to work 100% of the time on IE with it’s reliance on multiple versions of CaptiveX “technology” as opposed to virtually every other modern browser that processes native XMLHttpRequest commands.
IE7 is supposed to process native XMLHttpRequest commands I am happy to say but the legacy of M$ CaptiveX will live for some time to come.
There are a few things you will need to setup so I’ll email the java script code I use on the client side to you but you will have to modify it for your circumstances. You specify that you want to code the server side in .net. I use PHP scripting on a *NIX server so you are on your own about how to implement the server side. Perhaps some of the .net coders can give you a hand.
Note the request abort prior to setting up and issuing a request. If for some reason the server doesn’t complete processing the previous request in 10 seconds it is canceled prior to issuing the current request. If you have need for multiple request to be processing independently you will have to create multiple request objects and manage them appropriately.
I'm on-line therefore I am.

Hi Guys, i built a site for friends of mine and i want to publish it on the big search engines but i'm not sure how. First of all i'm looking to publish the site on google and then on other sites, so is there anyway to do that?
help would be greatly appreciated
thanx!

Here is a link to the Google page which lets you submit your site.
http://www.google.co.uk/addurl/?continue=/addurl[^]
Most search engines have similar pages if you look for them.
Words fade as the meanings change, but somehow, it don't bother me.

I'm going to describe my propblem the best i can, i dont know how clear it will come out.
I have a page where i want to edit information i have in a data table. however, i first must search for the particular row i want to edit. To do this, i have a textbox where the user can enter "field1" and then click a button called "search" which redirects them to a search page. field1 is passed using response.redirect to a textbox on the search page. a datagrid is generated from the value inside the textbox. to my datagrid, i added a select hyperlink to choose a specific row from the table (for each "field1" there can be multiple rows). when i click the select hyperlink in the datagrid i want it to redirect back to the edit page, but this time with more than just one field. I would like it to redirect back with a value for field1 and field2 where field2 is the primary key of the data table and is used on the edit page to generate a datagrid.
my problem is that i can not get the hyperlink to pass two values. when i add the new column to my datagrid and choose it to be a hyperlink, i tried entering two datafields in the "get url form datafield" option. ex: field2,field1. for the "url format string" i used ~/edit.aspx?field2={0}&field1={0}. i think there is a flaw in my syntax because when this is executed by the page, the value passed for field2 and field1 are the same even though they should be different numbers.
If anyone could understand that, i'd appreciate any info either about my syntax or a better way to go about handleing my problem.
Thanks

"url format string" i used ~/edit.aspx?field2={0}&field1={0}.
I think it should be
String.Format("/edit.aspx?field2={0}&field1={1}", VALUE1, VALUE2)

thanks, that worked perfectly

Hi everyone!
Is there any way to reliably track Mozilla's text zoom?
As a half-measure, I track Ctrl-+ keypress, but it doesn't work (ofcourse...) when user selects Text Zoom from the menu.
Any solution?
Best regards,
Dmitry.
