Hi Jan,

Its when i edit a nforum user and i try to upload an profile image, the line:
User user = new User(0); throw the error...

.......
Member m = Member.GetCurrentMember();
m.getProperty("profileImage").Value = GenerateImage(FileUploadControl).Id;
.......

        private Media GenerateImage(FileUpload ProfileImageUpload)
        {
            User user = new User(0);
         
            Media media = Media.MakeNew(CurrentMember.MemberLoginName, MediaType.GetByAlias("image"), user, MediaParentNodeId);

            string mediaPath = Server.MapPath("/media");
            string filePath = mediaPath + "/" + media.Id + "/" + ProfileImageUpload.PostedFile.FileName;

            Directory.CreateDirectory(mediaPath + "/" + media.Id);

            ProfileImageUpload.PostedFile.SaveAs(filePath);

            System.Drawing.Image.GetThumbnailImageAbort myCallback = new System.Drawing.Image.GetThumbnailImageAbort(ThumbnailCallback);

            Bitmap image = new Bitmap(ProfileImageUpload.PostedFile.InputStream);
            Bitmap thumb = (Bitmap)image.GetThumbnailImage(150, 150, myCallback, IntPtr.Zero);

            thumb.Save(filePath.Replace(".jpg", "_thumb.jpg"));

            media.getProperty("umbracoFile").Value = "/media/" + "/" + media.Id + "/" + ProfileImageUpload.PostedFile.FileName;

            return media;
        }

and i also have the : using umbraco.BusinessLogic; ...

hmmm, i just found out that it works when i haved a normal usercontrol in the umbraco site.
But its not working when i try from the nforum project where the dll is copied to my site...

Hi Jan, it was my "MediaParentNodeId" that caused the problem..

Problem solved.

is working on a reply...
