Webbupload Upload Component
Features
You can configure the Web. config file to set the size of the uploaded file.
It is fully developed Based on. NET and does not require any client configuration.
Provides synchronous upload progress bars to display real-time upload progress information.
Does not break the page logic. It provides usage similar to ASP. NET built-in Upload components.
Server. scripttimeout (request timeout setting) is not affected. You can configure the server processing time.
Development and testing environment
Operating System: Windows XP Professional (en)
Development Tool: Microsoft Visual Studio. NET 2003
Web server: IIS 5.0 &. NET Framework 1.1
Browser: Internet Explorer 6.0/
Update description:
1. modified the error when the object list item is empty during Multifile upload.
2. Updated the file name display method of the progress bar. Only the file name is retained and the path is deleted.

Second update from:
Download: http://files.cnblogs.com/WuCountry/WebbUploadSample.zip
Note:
1. modified the upload progress bar.
2. added several attributes and modified a class name. The original webbuploadhandler was changed to webbuploadstatushandler.
3. You can use the original upload method by calling the method enablewebbupload (false) when calling httpinpufile without interrupting the upload. Webbupload is used by default.
4. the demo is complete in the downloaded file.Source code.
I believe that this modification will make the component more and more stable and will be used in my actual project.

Yesterday, my colleague gave me a tool to reverse the DLL file into a project. Therefore, this Upload Component does not have to protect the source code.
Considering the Business Behavior of aspnetupload, the source code of this component is not disclosed for the time being, but this is meaningless.

Comment # Re: first update webbupload Wu. Country @ Xia yuan
I saw some questions discussed by my friends:
Http://computer.mblogger.cn/wucountry/posts/48947.aspx
The answer is as follows:
1. Technically speaking, when the webbupload component is used, the original upload method (using httppostedfile) cannot be used. The reason is a bit complicated. People who understand the way they work will understand it. Here we will explain: aspnetupload, sunriseupload.0.9.1 and Lion. web. uploadmodule V1.0 is the same, because these are technically the same, and they are nothing more than who wrote the script and who wrote it.AlgorithmThis makes the execution more efficient.
2. M_file.filename is blank? The Upload File class has two names: the client file name and the guid file name uploaded to the server. Check carefully. Check again.
3. The source code issue may not be made public yet, because the above aspnetupload is a commercial component and my component development is based on some of its ideas, so it is not made public for the moment. However, I still want to explain that on my blog, I have downloaded the source code sunriseupload.0.9.1, which is an open source outside China. It is similar to other components, but it is less efficient, you can also modify it. If it is used for learning, this is good. Reply
Your large file upload is very useful, but some of my original file upload processes are not available, including lion. Web. webhtmleditor. Can this problem be solved? Reply
# Re: first update webbupload OznAll your solutions are based on this article

For reference, you can write your own upload form and reply.
Oh, yeah, that's what I said: sunriseupload
However, the upload efficiency is too low. I can only refer to it for working principles, but I still have to write the algorithm myself. Otherwise, the local machine cannot test 1 Mb/s.
The aspnetupload can run 4 Mb/s and 3.5 Mb/s, all of which are tested on my computer.

Oh, it was a coincidence that there was no source code one minute ago. I accidentally flushed the source code out and replied.

There is a small description file in the demonstration document.
After all, it is not a commercial version and there is no user manual. I don't have time to write it either.
The help of aspnetupload is clear. You can refer to it. After all, the working mode is the same.
I have read that 70% of the functions and usage are the same. It should be helpful. Reply
I have a question about the code,
A byte array is created based on contentlength during HTTP request processing.
Does it mean that the size of the uploaded files will occupy the corresponding size in the memory?
If many people upload files to the server at the same time, they cannot crash?
I have never thought about this. Please give me some advice.

We need to fully trust our servers.
Haha, my components have not passed the stress test, so I am not good at answering your questions. It is possible that the components of aspnetupload have undergone stress testing. However, the principle is the same. If the server memory is large enough, it should still work. It is normal during testing on my 100 MB machine, and the memory usage may reach MB during one upload. But I have no better way, and there is always one between speed and memory consumption.

I found a lot about installing Microsoft on the Internet. web. UI. webcontrols articles are also taken according to the steps, but an error is still reported when running your component. I think the Treeview control is not successfully registered! In addition, I found thatProgramThe Microsoft. Web. UI. webcontrols. dll file does not exist in the bin directory.

# Re: Solution for uploading large files under Asp.net and source code of the webbupload component Wu. Country @ Xia yuan
The simplest method is to back up the source file you downloaded first.
Use the new file as the test project file, comment on the 1.1 point or delete the content you do not understand.
Until it can be run, until you fully understand, or only one line of statements is left ....
Then, compare the two projects and add new content to the deleted project in a row until it is exactly the same as the original one ....
This is a method I learned, and I hope it will be useful to the upstairs ....
About Microsoft. web. UI. webcontrols, the original private assembly, and later installed as a public assembly, so you may have a problem with your reference. After you download the latest installation package from the MS website, you just need to install it directly. This file is no longer needed in the local bin directory. However, when the local project is released, copy the file for version reasons. Reply

Grand brother Xia, what is this error after I compile it? Warning cs1607: Assembly generation -- referenced assembly 'webb. Wave. Controls. upload' is a localized satellite assembly
In addition, does the eldest brother Reply via email or QQ?
For some errors in the file, I really say it is very modest. Because this is extracted from my actual project, more or less of the content I failed to remove may cause some errors during compilation and running.
But this does not affect the use of components, because components are completely independent content, you can re-establish a new web project to test this component ........

Webb. Wave. Controls. webbupload has a resource file (unique). This is an HTML-based text file. Modify the English in the file to get the desired progress bar.
The display text of lable1 is dynamically modified, and it is static only to be seen during design. You can learn the basic knowledge of Asp.net. Reply

Check again. Your form must be able to upload files, that is, to add:
Enctype = "multipart/form-Data"
Or there may be other errors. refer to the example below.
Reply
Uploadfile UF = Wu. getuploadfile ("F ");
The getuploadfile method returns a null value,
I also wrote the sentence about form.
The Code is as follows:
Webbupload Wu = new webbupload ();
Uploadfile UF = Wu. getuploadfile ("file1 ");
If (UF! = NULL)
{
String filename = UF. clientfullpathname;
Filename = path. getfilename (filename );
String filepath = fyear + fmonth + fday + FH + FM + FS + filename;
String savepath = server. mappath (request. applicationpath) + "\" + configurationsettings. receivettings ["uppath"];
Savepath = savepath + "\" + filepath;
Uf. saveas (savepath );

Thank you for your help.
Now you can use the Upload Component in our 2005 project.
I want to ask why the file will be uploaded again after I refresh the page? (I deleted the uploaded files in the corresponding directory. After refreshing, the files are uploaded again)
How can this problem be solved?

This problem is simple. You can add your own logic on pageonload or commit events.
Or you can do some redirection and resource cleanup operations after uploading. This has nothing to do with components.
Thank you for your support for the components, and you can use them in 2005. Reply
Hello!
After using your sample and running it on vs2005, you can upload the file and the progressbar appears. But after the upload is complete, the page cannot be found. Is it related to vs2005? Reply
I am sorry for another problem.
If the size of the uploaded file exceeds the max value in Web. config, will it fail to find the leaf surface?
Thank you.
This is mainly because the above is too tight, so I have to ask first.

# Re: Solution for uploading large files under Asp.net and source code of the webbupload component Stupid little new
I took a look at source and found such a sentence.
Long m_requesttotalsize = convert. toint64 (m_workrequest.getknownrequestheader (11 ));
This sentence roughly gets the length of the uploaded file (it seems that it is not absolutely the same length, because it is the header length in principle. God knows what is contained in the HTTP protocol .)
This length seems to be known before the file is uploaded.
So there are two following statements:
Long m_maxsize = This. getuploadfilelength ();
If (m_requesttotalsize> m_maxsize)
{
Return;
}
M_maxsize is the maximum length defined in Web. config,
Therefore, I can write some code in front of the Return Statement to return the error message if it exceeds the predefined maximum length.
Can I understand this?
But the annoying thing is that this is the void function, and the return value cannot be used to reflect the result ....

I just found it under my web directory.

This type of file exists

And more than 900 MB. My original file is a rarfile, but it is only 6 MB.

About the previous issues.
During the test, I also encountered this problem.
This is mainly because resources are not cleared when I/O errors or exceptions are interrupted. Generally, such a file is not larger than a single uploaded file.
If you do not upload a MB file and the file appears, it indicates that your program has a problem and an endless loop may occur somewhere .. Check Carefully ...... Reply
Finally, make sure that you are prepared to modify and write the source code yourself, you may need to find several key bytes in hundreds of MB of data ........

I actually only use your sample. This problem also occurs. It is only used on vs2005.
In addition, this situation often occurs in the module.
Byte [] m_preloadedentitybody = m_workrequest.getpreloadedentitybody ();
M_preloadedentitybody can never get anything. It's so strange ....
I can get two results occasionally, but I cannot figure out how to get them ....
In addition, [you may need to find several key bytes in hundreds of MB of data...] What does this sentence mean? What will happen? I'm a cainiao. Don't scare me .....
Reply
In addition, can I use webbupload_beginrequest,
If the size of the uploaded file is greater than the value set in Web. config, the error page written by myself is directly returned. Can this requirement be met?
I originally wrote response. Redirect in application_beginrequest in global. asax, but it does not seem to work ?? Reply
What is this? After the download is too late, open it directly with vs.net.
Visual Studio. NET cannot create or open an application. The problem is probably because there is no setup required for installation on the Local Web server.
