The following code example gets the value of the Protection property to determine whether cell formatting is currently allowed. If cell formatting is not allowed, then the Protect method is called with the AllowFormattingCells parameter set to true so that cells can be formatted.

This example is for a document-level customization.

Private Sub ProtectCellFormatting()

    ' Protect cell contents, but do not change any  
    ' other protection type. This enables the Protection 
    ' property to have effect.
