Beta Experience セミナー (2006/07/25) デモ サンプルコード

環境：
Office Professional 2007 Beta 2
VSTO v3 JuneCTP

（→ このサンプルの Beta2TR 及び VSTO 2005 SE Beta 版は、ここ を参照してください）

こんにちは、松崎です。

2006/07/25 に実施予定の Beta Experience セミナーでご紹介するサンプルコードを Orland からアップします。
コードの詳細は、Beta Experience セミナーをご覧ください。

=================================================
カスタムタスクペインの表示

/** リボンなどから表示の切り替えをおこなう場合などは、下記の Visible の値を状態に応じて変更してください **/

        public UserControl1 myControl;
        public Microsoft.Office.Tools.CustomTaskPane myTaskpane;

        private void ThisApplication_Startup(object sender, System.EventArgs e)
        {
            myControl = new UserControl1();
            myTaskpane = this.CustomTaskPanes.Add(myControl, "My Test");
            myTaskpane.Visible = false;
        }

=================================================
OpenXML における カスタムXML Part の活用

添付：sample.docx      サンプルの解説で使用している docx ファイル
添付：test1.xsn           item3.xml を作成した InfoPath のフォームテンプレート

=================================================
Word Content Control への カスタムXML Part の XML ノードのバインド追加

<w:dataBinding w:prefixMappings="xmlns:c='http://schemas.microsoft.com/office/infopath/2003/myXSD/2006-07-18T03:20:17'" w:xpath="/c:myFields/c:Name" w:storeItemID="{3CC358D1-412F-459D-86EE-17DDD81CFED8}"/>

OpenXML へのプログラムからのアクセス

            }
            else
            {
                return false;
            }
        }

    }

=================================================
InfoPath VSTA を使った実装

Dim root, id As System.Xml.XPath.XPathNavigator
root = Me.MainDataSource.CreateNavigator()
id = root.SelectSingleNode("/my:myFields/my:field2", Me.NamespaceManager)
If id.Value.Equals("") Then
  id.SetValue(Guid.NewGuid().ToString())
End If

=================================================

以上です
