I'm currently working on custom file upload functionality in SPS 2003.

In this feature the user can able to upload any number of files on a single click in to the document library which he/she has access rights.

All the sharepoint services in the development environment are running under one common user (say ABC), the file uploading application uses impersonation option enabled and user name used was 'ABC' in order to get the full access to sharepoint objects. Otherwise I can not use any of the sharepoint objects with out impersonation.

The issue here I'm facing is who ever the uploads the file in to the sharepoint document library it takes the user 'ABC' in 'Last Modified By and Created By' fields in the file properties instead of the user who uploads the document. For example, if X has uploaded some files in to the document library. After uploading the files if he/she checks the file properties of Last Modified By and Created By values which appeared at the bottom of the page showing the impersonated user 'ABC' instead of 'X'.

Can any one help out in order to resolve this issue and update the respective user who uploads the file in to document library instead of impersonate user.
