hi,
thanks for your reply. i too thought the same that the entire page is rendered and there is no difference between master and content page.
But when i access the values posx and posy in a javascript function from the content page like this,
function fnZoomImage(comment_text)
{
oDiv = document.getElementById('idPOPUP');
if (oDiv != null) window.document.body.removeChild(oDiv);
oDiv = window.document.createElement("DIV");
oDiv.style.position="absolute";
oDiv.style.visibility = "visible";
oDiv.style.padding = "1px";
oDiv.style.width = "0px";
oDiv.style.height = "0px";
oDiv.style.border = "0px";
oDiv.style.left = posx + "px";
oDiv.style.top = posy + "px";
oDiv.id = "idPOPUP";
oDiv.innerHTML = ""+
""+
" "+
""+
""+
" " + comment_text + " |
";
window.document.body.appendChild(oDiv);
}
i get a error saying posx is undefined.
Thanks

Your script is a mess. Variable posx is declared inside a function, and you are accessing that from another function. This is not possible because variable posx scope ends when the first function ends. So how you can access it here ?
Try making posx declare outside the function. But I am not sure that you can access variables declared on different script blocks. If it's not working put a hidden textbox and assign the posx value there. Then read from this hidden textbox in the content page and assign to another variable.

hi,
I have a datagrid that loads data from sql server.
The datagrid is having in main page of the web site.
The problem is each time i refresh the main page, it took at least 10sec or more to load the datagrid due to lack of performance from the server.
Is there any way i can show a loading screen for datagrid so that customer can view the main page 1st??

10 sec ? Is it a long time ? I don't think so. If you are using MSAjax library, you can use a UpdateProgress control which will show update progress. But for using this your Datagrid should be in an UpdatePanel.
You have to optimize your query to get good performance. Usually DataGrid/GridView loads entire records to the grid even though you enabled paging. So if you are displaying large number of data with these controls, use custom paging. This can improve the performance.

actually 10 sec is less, but problem is the db server is slow due to super high traffic.....
so sometimes it goes 10s, 20s or even close to 1 min......
this will make the page so slow in loading becoz of datagrid....
i'm so new to ajax......any sample guidance????

Hi all,
I have been facing a problem for a long time and i am not able to get any flick.
The scenario:
I am running a webservice for entering the data into the my database on a regular interval from a different source.
The solution:
I am using threading model for the same. The threads (4 in no) keeps their job going seperately and then each one of them sleep inside a infinite loop for a predefined period to enter the data again. Even if there is any error i catch it and then start again, like i said the things in seperate threads are in infinite loop.
Consequence:
The service works perfectly fine but then the application stops. I have entered a code at the application stop event in Global.asax which i receive at any time. Sometimes the service runs through hours while at other times it stops at any time like 10 mins, 5 mins....
Problem:
Now i am not able find any appropriate cause of the problem. Why the application is behaving this was why is it stoping when i want that to run for the lifetime?
Any help ....!!!

Hi all,
I've been trying to display binary data from a database and for the most part I was successful. I have found tutorials on how to display images but, it seems there are not too many tutorials out there on displaying such things as word docs. I've been trying for a very long time now and it seems I'm getting nowhere. The two things I am most interested in regarding Binary Data are how to display them and pagination. I've bought and borrowed books for these purposes but they only touched on the subjects a little bit. I'm using ASP.NET 1.1 so many of the ASP.NET 2.0 tutorials out there are at this point of no use to me. If you know of a site that talks about what I'm looking for, please point me to it. Thanking in advance for your help.

Sorry pal as far as doc type is all you required from the data base, i have no clue haven't thought of before.
I think you should have tried the way the image is being displayed but that's image source mmmm.....
....will think over and tell you if there is anything.

What I've been trying to do is create a web app where users can submit their resumes, stories, etc. Then these files will be saved as binary data and stored in a database. They will be displayed when someone wants to see their contents. If there is a better way of doing that than saving them as binary data, I would like to hear about it. Thank you all for responding.

You can store the files in your server disk and keep the file path in database. But since you need to secure those files, it's better to keep them on database and binary.
Retrieving files from database and showing don't have any difference between showing images. First you need to set the content type to doc. Then use BinaryWrite(yourByteArray). See the below code, assume you have taken the file in a byte array say 'b'
Response.ContentType = "application/doc";
Response.BinaryWrite(b);
Hope it helps

Why do you want to store doc file in the database?
I thing it is not a good idea to store doc file or any other file in the database.You can also put it in the folder.Create one folder and put all files in that folder with the userId and that file extention.You can easily read or download that file from the folder and just store that file name in the database

I need to display an operation successful/unsuccessful message client-side, after server-side code determines if the operation was successful or not.. I know how to display javascript alerts on button clicks, but I need an alert determined by server code.. help meee  thanks. (Ps. I'm coding in C#)

On you event code, on completion, register the javascript with the ScriptManager. This can only be done during a postback, as the server can't push data to the client.
<br />
ScriptManager.RegisterClientScriptBlock(this, this.GetType(), "myuniquekey", @"alert('operation is complete');", true);<br />

I've got a custom asp.net 2 login authentication creating a generic principal object and working great except that I can't get the logout to truly abandon/clear. For most of the site, I'm using one master page, but for the secure area, I'm using another master page. The secure master page uses menus, with the logout being a menu item redirect to another page (login.aspx?id=logout) with request parameters to fire. When I click logout, it does indeed take me back to the login page. But, if I manually type in the page where I've just been, it lets me through without a login. I've tried researching the problem and implementing suggestions to others, but nothing has worked. Any help GREATLY appreciated.

Hi,
Can anyone provide me the regular Expression for validating the Person Names. That expression need to handle all types of names in the best way. The name contain alphanumerics and some special characters like _ , . .I don’t know exactly about any other type of special characters in names.

Go download a tool called Expresso. It will help you create RegEx expressions. This tool has many common RegEx expressions included with it, you might get lucky and it is there. If not, this is the tool I use to create my RegEx expressions.
If that tool doesn't help, look up some of the RegEx articles on CodeProject.
