Don't bind so much data to the grid view.

Good day,
I'm doing an ASP.NET web project. One of the site's functionallities is that the user can upload / download files ( the uploaded files are not supposed to be with size ovr 1 MB). Since there are about 10 000 visitors per day and A LOT of people download and upload files a big problem occured. As you know the hhtp web traffic and web space are quite expensive and 1000 people uploading and downloading 1mb files a day costs a lot.
So i decied to buy an FTP space where i'm going to upload and download the files.
Here i'm stuck! What is the best way to upload / download files on anftp server? I'm thinking of two ways:
1) The client anthenticates on the web server and uploads the files. The server uploads the files on the FTP
2) The clients directly authenticates on the ftp server and uploads files withougt the web server.
However the 1) has a disadvantage that the server makes "double traffic" ( one for receiving the file and one of uploading the file on an ftp server)
The 2) is that the password must be stored on the client and there is a serious security risk
Please Help
Best wishes, Hristiyan

To begin with 1MB is not that much of data by today's account

Do you expect all the people to upload 1MB of data? If so 10,000 x 1MB = 10,000MB = 10GB. Do you expect this to be daily uploads and downloads? If so, we have very high traffic.
Hristiyan wrote: So i decied to buy an FTP space where i'm going to upload and download the files.
How do you think FTP will solve you the storage space?
What is the realistic upload do you expect? How about download?
We have an application that can upload upto 700MB and servers thousands concurent users downloading files. I don't see where is your problem.
Now, as for ftp: if you have to do it with option 1, then why don't cut off the ftp and handle it in your own. If you can upload that much data, then you are all set

Maybe i didn't make myself clear. The project that i'm making requires that every day aroung 1000 to 5000 people are gonna upload / download files which are around 1 mb. I'm on a web hosting plan which requires $5 for each 5GB additional traffic. Which means 30x5$ = 150$ per month for additional web traffic and 5$ for each 5$ for each 500MB web space. You can immagine the sum.
Since i ALMOST don't benefit from my web site, thats quite an expense. So some time ago i saw some FTP hostings which are A LOT more affortable ( The FTP traffic is much cheaper, the ftp space is much cheaper). So my main idea is to store those files on an that kind of FTP server. However i need logic so i can upload files on that FTP server. In my oppinion there are two ways to achieve this:
1) The client authenticates to the web server -> Uploads the file on the web server -> The web server uploads the file on the FTP server. However this method has a disadvantage - the web server will have to make twice as much traffic. Once for the client to upload data on the web server and once for the web server to upload data on the ftp server.
2) When the client is uploading the file directly upload it on the FTP server withought the intervention of the web server. However this means that "somewhere on the client side" is supposed to be stored the password of the FTP server ( so the client can upload the file )
However i think that there might be a another way. Like:
The client authenticates to the web server. "Somehow the web server tells the ftp server that the client is gonna upload a file and the ftp server accepts the connection" ( Thats some really newbiesh way to explain it though )
Any suggestions ?
Best wishes, Hristiyan

because you coded it that way. Read your first paragraph. If you don't want to show the popup during development, comment out the code until you complete other sections

What is the value you have given for the 'classid' or else 'progid' property in the tag? If you are using this property give the value in the prescribed format xxxxxxxx-xxxx-xxxx-xxxx-xxxxxxxxxxxx
What is the control you are referencing using the object tag?

Hi friends,
Here i explain the requirments. If a user login he is activated in current members. If he logout using the logout button, he is deactivated. I did it using the database.
But the problem is if the user straightly closes the Browser window, his name was not deactivated in the database.
Can anyone tell how to solve the problem ??
|
|
|
|

Work with timeouts. As every user has its own session, you can catch the session-timeout-event. When this event fires you know that the user didn't take an action during the last xx minutes. Deactivate the user in your database according to this event.
Regards
Sebastian
P.S.: A handler for this event can be found in Global.asax.

Cant understand. Can u explain briefly?

It means you're probably not clever enough to be attempting this task. Which part of the clear explanation you were given used terms you're not able to comprehend ?
There is a better way, but it's also more complex, so there's probably no sense in trying to explain it.

Do the following:
1) Open the Global.asax-file of your ASP.NET project
2) Go to the method void Session_End(object sender, EventArgs e) ...
3) Call the method you are using to deactivate the user (if he clicks at the logout-button) within session_end
@Christian Graus: I'm interested in the better way to do this you mentioned. How does it work?

If the pages are popups, then you can do this using javascript. keep a reference to each open window and focus on it if someone tries to open it when it is already open.

Thanks for replaying
But these pages are not popups these are the master form ,
whats the requirement is that when once the form is open and user agian tries to open it it should not do any thing.
|
|
|
|
|
Keep a list of the open pages in a Session object. For each event that would open a page (clicking a link, clicking a button, etc), check the target page versus the session list and see if it exists. Open the page for the user based on that.
