Cathal,
thanks for your answer, but this did not really work. What I found out was the following:
01.string folder = String.Format("{0}myUploadFolder", base.PortalSettings.HomeDirectoryMapPath);
02.if (!(Directory.Exists(folder)))
03.{
04. FileSystemUtils.AddFolder(base.PortalSettings, base.PortalSettings.HomeDirectoryMapPath, "myUploadFolder", Convert.ToInt32(FolderController.StorageLocationTypes.InsecureFileSystem));
05.}
06.FolderInfo fi = FileSystemUtils.GetFolder(base.PortalId, "myUploadFolder");
07.
08.if (fi == null)
09. FileSystemUtils.SynchronizeFolder(base.PortalId, folder, "myUploadFolder", false, true, true, true);
10.
11.FolderPermissionCollection folderPermissions = fi.FolderPermissions;
12.if (!(FolderPermissionController.HasFolderPermission(folderPermissions, "Write")))
13.{
14. PermissionController permissionController = new PermissionController();
15. ArrayList arr = permissionController.GetPermissionByCodeAndKey("SYSTEM_FOLDER", "WRITE");
16.
17. FolderPermissionInfo folderPermission = new FolderPermissionInfo();
18. folderPermission.RoleID = -1;
19. folderPermission.PermissionID = 6;
20. folderPermission.AllowAccess = true;
21.
22. folderPermissions.Add(folderPermission);
23. FolderPermissionController.SaveFolderPermissions(fi);
24.}
When there is any "WRITE" permission on the folder (allowed or denied) for All Users, an exception is fired that there is already a permission defined.
When no permission is set, the permission will be set, but the file is not uploaded. After I log in as Administrator, I see the permission. I log out and try again - and it works.
Any idea?
Best wishes
Michael
