Question

I am unable to upload large files to Sharepoint 2010. I am using Visual Studio 2010 and Language C#. I have tried multiple ways from content I have found online but nothing has worked. I have changed the settings and config files to the maximum allowed upload limits and still nothing. I am using the copy.asmx for small files which works fine and am trying UploadDataAsync when the file is too large and an exception is thrown but this is not working. Please take a look at the code below…

Any/all assistance is greatly appreciated.
