Set file to 'Hidden' in Windows

Targets Windows
1

Is there a way to set the attribute of a file to ‘hidden’ in code in Windows?
The file attributes are read-only.
I imagine I could shell to attrib.exe with +H parameter but want to avoid the DOS window that would appear briefly.
Cant find anything MBS-wise either at the moment…

2 
Dim x As Folderitem
x.Visible = False
3

The shell window does not appear when using Shell…

However, Christophe posted the best solution for that particular case.

4 
x.Visible = False

The docs do say that, but…

Actually, I marked it as the best solution too soon.
It doesn’t seem to be working (at least on OSX, and yes I know I started talking about Windows, but a simple . sorts it out on a Mac and Im trying to keep as much shared code as I can)

It works just fine here. But in Mac OS X or Linux, you must have write permissions.

This lifts the read only permission before changing visible, then puts it back :

dim f as folderitem = SpecialFolder.desktop.child("Keep it working - Thunderbird - MozillaZine Knowledge Base.webloc") dim previousPermissions as integer = f.Permissions f.visible = not f.visible f.permissions = previousPermissions

You need to use #If not TargetWin32 since Windows does not support permissions.

Not read only, so I don’t need the permissions aspect here… I am creating the file.

Currently I can only get it to work if I save the file, then set the folder item to nil, then get a new reference and set visible = false

   [code]   f2 = GetFolderItem(thepath)
      f2.SaveAsJPEG thepicture
      f2 = nil
      f2 = GetFolderItem(thepath)
      f2.Visible = false[/code]

You do not give enough time for the system to finish closing the file. Set visible in a timer a couple ticks away.
