Steps to Set a File to Read-Only Using Windows

1. In Microsoft Excel, open up a new workbook and save it to the C:\ folder (directory) with the name "C:\Test.xls."

2. Close Test.xls, and in Windows Explorer (Windows File Manager in versions earlier than Windows 95), select the file you saved in Step 1.

3. On the File menu, click Properties.

4. In the file's Properties box, click to select the Read-only check box, and then click OK.

Steps to Set a File to Read-Only using the Macintosh

1. In Microsoft Excel, open a new workbook and save it as "Test" to the hard disk.

2. Close Test and hide Microsoft Excel. On the desktop, open your hard disk by double-clicking the hard disk icon.

3. Highlight "Test," click the File menu, and then click Get Info.

4. Click on Locked, then click on the close button in the upper-left corner of the Info box.

Sample Visual Basic Procedures

Example 1: A Macro to Determine if File's Read-Only Attribute is Set

The following macro will determine if a file's read-only attribute is set. Open the file you created above, and then type the macros below in a module sheet.

Sub Example1()

    ' Test to see if the Read-only attribute was assigned to the file.

    If GetAttr("c:\test.xls") And vbReadOnly Then
        MsgBox "File is Read-only"
    Else
        MsgBox "File is not read-only"
    End If

End Sub

Note: If you are working on a Macintosh, substitute the harddisk's name and "test" for "c:\test.xls". For example, if your harddisk's name is "HD", you would type GetAttr("HD:test").

Example 2: A Macro to Determine if Active Workbook is Opened as Read-Only

The following macro will determine if the active workbook is opened as read-only.

Sub Example2()

    ' Check to see if the active workbook was
    ' opened as read-only within Microsoft Excel.

    If ActiveWorkbook.ReadOnly Then
        MsgBox "File was opened as read-only"
    Else
        MsgBox "File was not opened as read-only"
    End If

End Sub
