Hi Experts,

Hi ,
  Thanks for your quick response.

   I have tried with this. but still it is giving the same problem. If you have the sample code can you please share it.


Hi mohan
I never got around using something like this but there were plans.  So i dont have anything like that. Do a google serach for "sharepoint impersonating" or "moss impersonating", you should get a lot of samples. But if i were you i would check that the user that you are traying to impersonate can do this! Also did you check if there are any restrictions on the page ur traying to upload? DId you try and log in as the actual user you are impersonating and upload a file to the same site onto a different library and the same library and see if you get any errors/restrictions?

Thanks for the solution
Your help has saved me hundreds of hours of internet surfing.
