範例

下列程式碼範例會將新的 BuildingBlockGalleryContentControl 加入至文件的開頭。 BuildingBlockGalleryContentControl 會顯示 Microsoft Office Word 所提供的方程式建置組塊 (Building Block)。 這個範例會將 PlaceholderText 屬性設定為提示使用者選擇方程式的字串。

這是示範文件層級自訂的版本。 若要使用這段程式碼,請將它貼到專案的 ThisDocument 類別中,並從 ThisDocument_Startup 方法呼叫 AddBuildingBlockControlAtSelection 方法。

Dim buildingBlockGalleryControl1 As Microsoft.Office.Tools.Word.BuildingBlockGalleryContentControl

Private Sub AddBuildingBlockGalleryControlAtSelection()
    Me.Paragraphs(1).Range.InsertParagraphBefore()
    Me.Paragraphs(1).Range.Select()
    buildingBlockGalleryControl1 = Me.Controls.AddBuildingBlockGalleryContentControl( _
        "buildingBlockGalleryControl1")
    With buildingBlockGalleryControl1
        .PlaceholderText = "Choose an equation"
        .BuildingBlockCategory = "Built-In"
        .BuildingBlockType = Word.WdBuildingBlockTypes.wdTypeEquations
    End With
End Sub
private Microsoft.Office.Tools.Word.BuildingBlockGalleryContentControl buildingBlockControl1;

private void AddBuildingBlockControlAtSelection()
{
    this.Paragraphs[1].Range.InsertParagraphBefore();
    this.Paragraphs[1].Range.Select();

    buildingBlockControl1 = this.Controls.AddBuildingBlockGalleryContentControl(
        "buildingBlockControl1");
    buildingBlockControl1.PlaceholderText = "Choose an equation";
    buildingBlockControl1.BuildingBlockCategory = "Built-In";
    buildingBlockControl1.BuildingBlockType = Word.WdBuildingBlockTypes.wdTypeEquations;
}

這是示範應用程式層級增益集的版本。 若要使用這段程式碼,請將它貼到專案的 ThisAddIn 類別中,並從 ThisAddIn_Startup 方法呼叫 AddBuildingBlockControlAtSelection 方法。

Dim buildingBlockGalleryControl1 As BuildingBlockGalleryContentControl

Private Sub AddBuildingBlockGalleryControlAtSelection()
    If Me.Application.ActiveDocument Is Nothing Then
        Return
    End If

    Dim vstoDoc As Document = Globals.Factory.GetVstoObject(Me.Application.ActiveDocument)
    vstoDoc.Paragraphs(1).Range.InsertParagraphBefore()
    vstoDoc.Paragraphs(1).Range.Select()
    buildingBlockGalleryControl1 = vstoDoc.Controls.AddBuildingBlockGalleryContentControl( _
        "buildingBlockGalleryControl1")
    With buildingBlockGalleryControl1
        .PlaceholderText = "Choose an equation"
        .BuildingBlockCategory = "Built-In"
        .BuildingBlockType = Word.WdBuildingBlockTypes.wdTypeEquations
    End With
End Sub
private Microsoft.Office.Tools.Word.BuildingBlockGalleryContentControl buildingBlockControl1;

private void AddBuildingBlockControlAtSelection()
{
    if (this.Application.ActiveDocument == null)
        return;

    Document vstoDoc = Globals.Factory.GetVstoObject(this.Application.ActiveDocument);
    vstoDoc.Paragraphs[1].Range.InsertParagraphBefore();
    vstoDoc.Paragraphs[1].Range.Select();

    buildingBlockControl1 = vstoDoc.Controls.AddBuildingBlockGalleryContentControl(
        "buildingBlockControl1");
    buildingBlockControl1.PlaceholderText = "Choose an equation";
    buildingBlockControl1.BuildingBlockCategory = "Built-In";
    buildingBlockControl1.BuildingBlockType = Word.WdBuildingBlockTypes.wdTypeEquations;
}
