Form.SetDesktopLocation メソッド
アセンブリ: System.Windows.Forms (system.windows.forms.dll 内)


デスクトップ座標は、タスクバーを除外した画面の作業領域に基づきます。このメソッドを使用すると、デスクトップ上のフォームの位置を設定できます。デスクトップ座標はフォームの作業領域に基づいているため、このメソッドを使用すると、フォームをデスクトップ上に確実に表示できます。このメソッドは主にトップレベル フォームに対して使用されます。マルチ ドキュメント インターフェイス (MDI) 子フォームを配置する場合は、LayoutMdi メソッドを使用してください。

SetDesktopLocation メンバ、Load メンバ、および Activate メンバの使用方法を示すコード例を次に示します。この例を実行するには、1 つのボタン コントロール (Button1) と 2 つの Label コントロール (Label1 および Label2) が配置された、Form1 という名前のフォームに、次のコードを貼り付けます。
Shared x As Integer = 200 Shared y As Integer = 200 Private Sub Button1_Click(ByVal sender As System.Object, _ ByVal e As System.EventArgs) Handles Button1.Click ' Create a new Form1 and set its Visible property to true. Dim form2 As New Form1 form2.Visible = True ' Set the new form's desktop location so it appears below and ' to the right of the current form. form2.SetDesktopLocation(x, y) x += 30 y += 30 ' Keep the current form active by calling the Activate method. Me.Activate() Me.Button1.Enabled = False End Sub ' Updates the label text to reflect the current values of x and y, ' which was were incremented in the Button1 control's click event.
