I need a.dll file called by my ASP.Net app to write files to a sub folder but I am confused about what a User actually is and how I control what User account my app uses by default. I have a folder named Camera and a User named Camera and I have given Read/Write permissions for the Camera folder to the User Camera but my app is unable to write .jpg images into the folder. Where am I going wrong?
It depends on how your application is written but generally, you should allow the anonymous user to have read / write permssion.
Unfortunately the anonymous user does not appear in the dropdown list of users to grant permission to.
permission looks ok to me. i suggest you open a support ticket and provide us with details on how to replicate the problem.
