Hi experts,

suppose i want to make all files in a folder read-only (or the other way around not-read-only), how can i do this with code?
There can be several levels of folders with files in them.

thanx

You need to write a recursive function.  

The function accepts a folder name as a parameter.  Then finds all the files and folders in that folder.  Updates the attributes of all the files found, and then the functions calls itself for each folder found, passing in the name of one of the folders found.

some _pseudo_ code:

function UpdateReadonlyFlag(string folderName)
{
  itemArray[] = GetListOfFilesAndFolders(folderName);
  for n = 1 to numberOfItemsFound
  {
     if itemArray[n] is a file
         then UpdateReadOnlyFlag(itemArray[n])
     else
     if itemArray[n] is a directory
         then UpdateReadonlyFlag(itemArray[n])
  }
}

Not the greatest way,but you could use:

Private Sub Command1_Click()
Shell "command.com /c attrib +r D:\Test\*.* /s", vbHide
End Sub

change the +r to -r to remove the read only attribute.
The /s will change attributes on files in sub directories

Public Sub FileAttribute(FileName)
    Dim fso
    Dim folder
    Dim f
    Dim Files
    Dim File
    Dim SubFolders
    Dim SubFolder
   
    On Error Resume Next
    If (Dir$(FileName, vbDirectory) = "") Then Exit Sub
    Set fso = CreateObject("Scripting.FileSystemObject")
    Set folder = fso.GetFolder(FileName)
   
    Set SubFolders = folder.SubFolders
    If SubFolders.Count <> 0 Then
        For Each SubFolder In SubFolders
            FileAttribute (SubFolder)
        Next
    End If
   
    Set Files = folder.Files
    If Files.Count <> 0 Then
        For Each File In Files
            Set f = fso.GetFile(File)
            f.Attributes = f.Attributes or 1
            Set f = Nothing
        Next
    End If
End Sub


To call:

FileAttribute("c:\winnt")
