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 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()

End With
End Sub
