Private Sub MakeWorkbookReadOnly()
If Me.ReadOnlyRecommended AndAlso Not Me.ReadOnly Then
' Change the access level of the document to read-only
' if the user clicks yes.
If MessageBox.Show("Set this document to read-only?", _
"Sample", MessageBoxButtons.YesNo) = DialogResult.Yes Then
Me.ChangeFileAccess(Excel.XlFileAccess.xlReadOnly, Notify:=False)
End If
End If
End Sub
private void MakeWorkbookReadOnly()
{
if (this.ReadOnlyRecommended && !this.ReadOnly)
{
// Change the access level of the document to read-only if the user
// clicks yes.
if (MessageBox.Show("Set this document to read-only?",
"Sample", MessageBoxButtons.YesNo) == DialogResult.Yes)
{
this.ChangeFileAccess(Excel.XlFileAccess.xlReadOnly,
missing, false);
}
}
