can you give an example to how to use div tag in regular expressions

DIV tag has no relation with regular expressions. Regular expressions are patterns used to find/replace specific text. It looks like you need a book on regular expressions. Try programs like RegExBuddy/Expresso which will help you to build regular expressions.

any ideas for file upload solution

22-Dec-08 20:43

This question has bugger all to do with ASP.NET. ASP.NET is the one thing you can't possibly use to copy websites.

Hello everyone,

My problem is,

1. I want to let end user to fill-in an Excel file, which contains two columns, file description and file location on client side;

2. I want to let end user to upload the Excel file to my web server, then I want my web server to find the files specified in Excel file and upload them into web server.

Any documents or samples for me to start with?

thanks in advance,
George

Thanks Abhijit,

I read this sample, but I think it is not what I want. I want the end user to submit an Excel file which contains all submit file items, and then the web application could automatically retrieve/upload the file items.

Any comments or ideas for my solution?

regards,
George

This is not possible in ASP.NET. ASP.NET sits on server and can't access any file in the client machine.

Thanks Navaneeth!

My confusion is, I want to provide a convenient user interface to end user. The end user needs to submit a lot of files and related description. I do not want to let them select them one by one and enter description one by one. I want them to submit all at once. So, it is why I want them to submit an Excel file.

Anyway, if you think my idea is not good enough, it is fine. Smile | :)

Then, what is your idea to achieve my goal of imporving user experience to submit a lot of materials?

regards,
George

Since it is a web application, you have lot of restrictions in providing convenient user interface for upload. You have no other option than selecting files one by one. I have seen some flash based uploads which allows to select multiple files at one shot. But don't know how they did it as I don't know flash.

Smile | :)

Thanks Navaneeth,

I am thinking of your solution seriously and finding alternative solutions. My current idea is to let end user submit a zip file which contains all individual files. But my concern is whether subsmit such big zip file will be slow and impact server performance? Any best practices or performance tuning technologies for uploading file to server?

regards,
George

Christian Graus22-Dec-08 22:02

Tell them to zip the materials and send a zip. Seriously, ASP.NET generates HTML, as Navaneeth said, without a java or flash control, there's no way you can do any different.

Thanks Christian,

Will it be slow if they send the zip file altogether to server?

CG was joking, I believe. You can do what he said. But that will be slower than selecting each files and uploading. First of all you have to configure ASP.NET settings to allow large files. When the zip file successfully uploaded, you need to unzip it and place files in right place in the server.

At the end of the day you will notice that uploading files one by one is the most straightforward solution.

Thanks Navaneeth,

1.

I want to confirm with you whether do you think upload one big zip file is better or not, why? Sorry, I am confused.

2.

"First of all you have to configure ASP.NET settings to allow large files." -- do you have any documents about this?

That depends. As christian said, if your users will be uploading only text files or doc files, then zipping the file and uploading at one shot will be better. But if users will be uploading videos or images, no further compression is possible even if they zip it. So you don't find any difference.

It is a configuration entry in web.config file. You need to increase maximum request length allowed. See this[^]

Thanks Navaneeth!

I am thinking seriously about whether writing a client side program to upload file is better. But I do not know whether it is better because of my limited experience. Each time file upload size is big, may be several hundred M bytes, so I suspect the capability of uploading from browser.

What is your idea?

regards,
George

Christian Graus22-Dec-08 23:27

22-Dec-08 23:27

It depends. If it's a bunch of small files, then it will be fine. If they are a fair size, then you'll hit the wall of your page timing out. Either way, it will be faster if the files are text based ( that is, if they will zip to somethig a lot smaller ) and the same time if they are a png or something ( so, the file size is the same ). An advantage of a user sending a zip is, you'll know for sure you got it all, if you didn't, the zip will be invalid.

Requiring your users to make a zip is probably not ideal, but it's not a bad idea to support them.

Thanks Christian,

Compared with uploading one big zip file, do you have any better ideas for browser based solution? (I can not let client install any non-browser software, like FTP client to upload.)

George

This is retarded. The file is stored on your server, therefore, once you deploy this app, the client will not have the web app running on their local machine, and therefore any link you create, will not work, obviously.
