    Re: Ajax file uploader for large files not working fine

    Suvradeep,
     
    Do you have problems with the small size files?
     
    If not, please check the following article:
     
     

    IIS7 and large files

    By default in IIS 7 requestFiltering  has the MaxAllowedContentLength property enabled. It specifies, in bytes, the maximum length of the content in a request. The default is 30,000,000 (approximately 30 megabytes.) To change this value you must edit the following file:

    %windir%\System32\inetsrv\config\applicationHost.config.

    In the ApplicationHost.config file, locate the <requestLimits> node.

    Modify the following code.

    <requestLimits maxAllowedContentLength ="10000000" />

    Re: Ajax file uploader for large files not working fine

    Hi,
     
    Can you test
     
    e.MoveTo(path + "\\" + e.FileName);
     
    instead of
     
    e.CopyTo(path + "\\" + e.FileName);
     
    ??
     
    copy a large file would spend a lot of time.
     
    Regards,
    Terry

    Re: Ajax file uploader for large files not working fine

    Thanks Adam for replying,
    The files have send me still not works.
    I am summerizing the problems that i am facing,

    1>I cannot save the uploaded file to my desired location,though the file gets saved to a temp folder created by ur tool,i tried with CopyTo() and MoveTo() methods.

    2>If i set a breakpoint on
       void Uploader_FileUploaded(object sender, UploaderEventArgs args)

    the breakpoint is not catching the event so i cannot see the control flow also i cannot view the event working for me

    3>After upload compleates to a temp folder i am getting a weired messege something like "Http error1 1: 12031:Unknown"
    i've googled with this and i found i messege means:
     
    12031       ERROR_INTERNET_CONNECTION_RESET
                   The connection with the server has been reset.
    also found this may an error caused by updatepanel[not sure].

    plz let me know what is happening...

    Thanks

    <html>
    <head>

     </CuteWebUI:Uploader> 
        </form>
    </body>
    </html>
     
    Can you try the following file?
