使用例

PrintDialog コントロールを使用して、AllowSomePages、ShowHelp、および Document の各プロパティを設定するコード例を次に示します。この例を実行するには、PrintDialog1 という名前の PrintDialog コントロールと Button1 という名前のボタンが配置されているフォームに、次のコードを貼り付けます。この例は、ボタンの Click イベントおよび docToPrint の PrintPage イベントが、この例で定義されているイベント処理メソッドに関連付けられていることを前提にしています。

' Declare the PrintDocument object.
Private WithEvents docToPrint As New Printing.PrintDocument

' This method will set properties on the PrintDialog object and
' then display the dialog.
Private Sub Button1_Click(ByVal sender As System.Object, _
    ByVal e As System.EventArgs) Handles Button1.Click

    ' Allow the user to choose the page range he or she would
    ' like to print.
    PrintDialog1.AllowSomePages = True

    ' Show the help button.
    PrintDialog1.ShowHelp = True

    ' Set the Document property to the PrintDocument for 
    ' which the PrintPage Event has been handled. To display the
    ' dialog, either this property or the PrinterSettings property 
    ' must be set 
    PrintDialog1.Document = docToPrint

    Dim result As DialogResult = PrintDialog1.ShowDialog()

    ' If the result is OK then print the document.
    If (result = DialogResult.OK) Then
        docToPrint.Print()
    End If

End Sub

' by handling the document's PrintPage event.

   ByVal e As System.Drawing.Printing.PrintPageEventArgs) _
