any way can you suggest the uploading large file by streaming with out using database...
You're not getting it. Streaming in this case is the streaming of the file, from the file upload control, on the server, to the database. It has nothing to do with uploading files faster, in fact, it's probably a tiny bit slower. It's for saving memory on the server side.
Accha i have a question.. how rapidshare and other file upload sites manage their uploads..??
Probably by writing a java ( or .NET if it's IE only ) control and embedding it within the page. Then you can do any sort of operation you like, including selecting multiple files, etc. I use Godaddy as a web host, and their FTP client is written in Java, for example.
Ok now i got you.. dont bother about the time... send me some useful syntax of streaming the file from the upload control, to the server ( here i am using my local machine.. so i want to upload file to c:\uploadFiles\ )
I need to extract some of the data from third party website. I know we can retrive data from the div tags. but programatically how can i know the view source of that html page. I explictly know that tag name.
How can i use programatically to retive that one.
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.
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.
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.
Then, what is your idea to achieve my goal of imporving user experience to submit a lot of materials?
I want to provide a convenient user interface to end user
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.
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?
