I dont Know Much abt servlet context ..!But what are you tring to do ?If you tell what u want to do .Group can help you go in the right direction..!

i apologize; in my asp.net app i have a list of values taken from the db, for ex: list of items, this list
of items will be displayed in several pages in combo boxes. what i want to know is without going to db each time i need to show the items is there a way to take them at first attempt and keep them ,that will be used with in many pages.
what is the standard way ?
this can be done in java using the servlet context.

1.Create a class file for that particular table using GetSet method(Say Calss1)
2. Execute your Query (optional ExecuteReader)
if ExecuteReader
-----------------
SqlDataReader Dreader = thisCommand.ExecuteReader();
List<TblValue> lstTblValue= new List<TblValue>();
while (Dreader .Read())
{
Calss1 objClass= new Calss1();
objClass.TblFiled1= Dreader["TblFld1"];
objClass.TblFiled2= Dreader["TblFld2"];
TblValue.Add(objClass);
}
close the db connection
4. Now this list will have your returned column value, and objClass will have the result from the table for ever ( until next execution hits that class)modified on Wednesday, February 10, 2010 2:32 AM

| If this list is user specific then you can put in Session varialble and if not User specific then you can put it in Application variable or Cache. Cheers!!

Suppose I have a web application which accepts a small amount of data from the client (so the data transfer is not an issue), then performs some very lengthy operation (minutes or tens of minutes) on the server, and returns the result back to the user. My question is - what is the preferred method of dealing with long requests? If I use regular postback, the browser will wait for the response and time out prematurely. Increasing the timeout is not a solution, because I do not want the browser to get stuck and seem unresponsive for so long.
One way I thought of is running the time-consuming operation in another thread. This way the server response is sent immediately, so there is no timeout problem. Then I use periodical page refresh to check if the thread finished its work - it displays either "Please wait" on each negative check or "Finished" with the results. The drawback of this approach is that the time intervals in which I check if the work is done are constant (say 10 secs), so even if the work happened to be very fast (finished immeditely), the user has to wait for at least 10 seconds before the first check requst is sent. Is there any way the server itself can inform when the operation is finished?
Any help regarding this matter is appreciated, I suppose this must be a well-known issue so I'll be happy if you just point me the right way.

This is the type of operation ajax was meant to handle. You can display some type of progress indicator on the page while waiting for the response with no need to continually refresh the page.

| One another way apart from Ajax as suggested by Mark, you can use Asp.Net callback to get the better response time. Cheers!!

Place a application state value at the end of the process(long execution)
check if there is a entry in AppValue, If it is so then the process should be completed. and take the user to corresponding page

Hi all,
1. I have a Virtual Dedicated Server.
2. I am getting "Unable to load DLL 'LCE.dll': Access is denied. (Exception from HRESULT: 0x80070005 (E_ACCESSDENIED))" where LCE.DLL is a C++ dll.
3. I have .NET dll that access the C++ dll.
The error occurs when I try to call a function in the c++ dll.
//__declspec(dllexport) int __stdcall siv(LPWSTR inbuf, int seed, bool div) C++
[DllImport(@"LCE.dll")] //C#
public static extern int siv([MarshalAs(UnmanagedType.LPWStr)]string outbuf, int x, bool b);
I am pretty certain that it is NOT the dll but the permissions on the bin directory of the web site, I have tried a number of things to give the permissions to execute the dll but nothing has worked so far.
Does anyone know or point me in the direction where I can resolve this issue

Hi
I am looking for a solution to a Java Script question. My question is this, I have a gridview, and in this gridview I have a column, which I use as a flag. The gridview itself is dynamically added to a user control and then to the page. What I would like to do is to use Java Script to hide this column, but I do not know how to do this. Unfortunately, I cannot use code behind, because of the gridview being dynamically added.
Also, I have one further question, I already have some Java Script code that can hide some of the rows based upon the values in my column when a button is clicked. What I want to do is when the page is loaded for the first time, to hide some of these rows, and to use the button in reverse to reveal them again. How do I achieve this?
Thanks

Look at the JQuery [^]library, it makes tasks like this very easy.
$("td.flag").hide();
This simple bit will hide any TD element with the class name flag.

I just had a quick look at this, and I am slightly confused as to how I can use JQuery to hide the rows when the page is first loaded; then to use a button show them, or hide them based on a click. Please explain.

Have you read the documentation for JQuery?
$(document).ready(function()
{
$("tr.hidden").hide();
$("button").click(function(){ $("tr.hidden").show(); });
}
This script will run when the page is loaded and hide any TR element with the class hidden. It will also hook up the click event of the button to show all TR elements with the class hidden when clicked.

Hi
Yes, I had a brief look at the article, and I got the general idea. You to excuse my ignorance, but I have never used JQuery before. So, it take me a few days to get use to it.
However, in my current JavaScript, I have a function which I have called ShowAll. This function does the reverse what I really want to do. To get to my gridview, I am using getElementByID to find the div where the gridview I want to use is located, and then childNodes for the gridview I want. To get to the rows, I am using getElementsByTagName to find all the rows, and then a for loop with an if for the logic.
So, my question is whether I can nest the JQuery into the JavaScript to work with the gridview I want. Is this possible?

One, it is an entire website, not an article. Two, take a better look and your question will be answered.
Your JavaScript, as you describe it, is convoluted and unnecessary and shows a lack of understanding about how to use JavaScript.

Hi
I am not sure what has happened here, but I have 3 panels, and these 3 panels are nested inside one large, thus:
<asp:panel id="pnlMain" runat="server" height="60%" width="100%">
<asp:panel id="panel1" runat="server" height="100%" width="100" scrollbars="vertical">
<asp:panel id="panel2" runat="server" height="100%" width="100" scrollbars="vertical">
<asp:panel id="panel3" runat="server" height="100%" width="100" scrollbars="vertical">
What is happening is that when I add my gridviews to these nested panels, the panel is just getting larger, the scroll bars are not scrolling, in other words the panels are stretching rather than their height staying fixed.
How do I fix this?
Thanks

Because you are specifying the heights to be a percentage, not a fixed size. It's doing as you have asked.

Wouldn't setting the size as a pixel stop the panel fitting any browser size resolution?

You can't have it both ways
