Hi,
I found this answer helped to solve my problem with image caching. I thought i will share with the group..Thanks to Benjamin..
Previous problem:
I am uploading an image and replacing existing image. I have upload button that I am uploading the image with. How can I write code such that the uploaded image displays immediately.
If I use different file name for the image the file displays by setting up imageurl. However if I want to use the same file name as this image has to be displayed in other web application that runs on asp, the image does not load until I do a manual refresh of the page. It does not load even if I do a response.redirect to the same page. I believe it may be cache problem, if it is how to rectify it?

You can configure this in IIS MMC by navigating to the folder containing the
images and adjusting the HTTP Headers to either "expire immediately" or
"never expire".

Perhaps you could identify what parts you don't understand and what you have tried so far. If you want to learn, then ask. If you want it done, then buy it.

How could i print a web form in ASP.NET on Dotmetrix printer
IE6 takes its default print size A4 and it leaves the page,
what i want is the printer will stop after printing the form and the next job of printing will be print on same page.
|

I don't quite understand what the problem is? It being a dotmatrix printer has nothing to do with it (least no anything you can change). IE6 (or any browser) is pretty rubbish at formating web pages for print. You want to look at creating a CSS print style sheet.

Hi friends,
I have a web form with a ListView bound to a DataView. I need to fire the OnSelectedIndexChanged event to capture the index in the ListView in order to retrieve the data from the DataView.
The problem I have is that this event does not fires when I click on a different item in the LV. It only fires when I change its content by filtering the DV etc...
What is happening here?...Is this event not suppose to fires when a user change their selection in the LV?
Thanks

Now on the click of the SUBMIT button.. i want all these selected items to be stored in a database.. obviously... i want an upper limit for the same.

secondly.. wen these items would be saved.. how would i retrieve their corresponding details from the other table.
thirdly.. any help in javascript to fix the upper limit.. need at client side..

Hi!
Well, you should read these listbox item by item and load the selected items in a array, then send this array element by element to the table in the database using sql statements.
|
|
|
|
|
i tried a lot, but no luck
i initialized a string type array with size 6.
string[] items = new string;
now how should i connect it with the listbox items.

(1) add one column in a user table (IsLocked)
(2) when user submit user name and password maintain a counter in session variable
(3) if counter is 3 then update the table with the IsLocked property true
and then show the message........
cheack each postback with the database if IsLocked propert true then show message and make the control disable.

Here i m just providing logic. I think this may be helpful to you.
Steps :
1. Declare a PWDCheck function which will recive username and pwd as an arguments.
2. Function will check the username and pwd against database userDetails table.
3. You have to declare a static variable, and increment the value of that variable, when pwd is invalid.
4. For locking the users a/c. In database, UserDetails table we should have a status variable for storing locking status.
5. If the value of the variable reaches to 3 then you update userdetails status variable to true.
