    AddHandler vstoDoc.BeforePrint, AddressOf ThisDocument_BeforePrint
End Sub

Private Sub ThisDocument_BeforePrint(ByVal sender As Object, ByVal e As System. _
    ComponentModel.CancelEventArgs)
    Dim vstoDoc As Document = Globals.Factory.GetVstoObject(Me.Application.ActiveDocument)
    If System.Windows.Forms.MessageBox.Show("Do you want to print the document?", "BeforePrint", _
        System.Windows.Forms.MessageBoxButtons.YesNo) = System.Windows.Forms.DialogResult.No Then
        e.Cancel = True
    End If
End Sub
private void DocumentBeforePrint()
{
    Document vstoDoc = Globals.Factory.GetVstoObject(this.Application.ActiveDocument);
    vstoDoc.BeforePrint += new System.ComponentModel.CancelEventHandler(ThisDocument_BeforePrint);
}

void ThisDocument_BeforePrint(object sender, System.ComponentModel.CancelEventArgs e)
{
    if (System.Windows.Forms.MessageBox.Show("Do you want to print the document?", "BeforePrint",
        System.Windows.Forms.MessageBoxButtons.YesNo) == System.Windows.Forms.DialogResult.No)
    {
        e.Cancel = true;
    }
}
