And creating the page folder and storing files in it is also is tied to the page security.

Create page folder without UnauthorizedAccessException
binär optionen lernen The easiest way to to get the page folder from code is to call CurrentPage.GetPageDirectory(true) but it will only work if the folder already exist or if you are logged in as an editor with the right to create pages. This is how to do it your current user does not have the needed page access:

Change a files meta data using BypassAccessCheck
The method to use BypassAccessCheck can also be used to modify a file or its meta data if your code is running as a anonymous visitor.
//Get the file you want to change
UnifiedFile file = (UnifiedFile)GenericHostingEnvironment.VirtualPathProvider.GetFile(UploadedImage.ImageUrl);
file.BypassAccessCheck = true;
//Modify meta data and save
file.Summary.Title = TitleTextBox.Text;
file.Summary.Author = AuthorTextBox.Text;
file.Summary.Subject = DescriptionTextBox.Text;
file.Summary.Dictionary[IsApproved] = "Y";
God luck with your upload function!
