此版本针对的是文档级自定义项。 若要使用此代码,请将其粘贴到项目内的 ThisDocument 类中,然后从 ThisDocument_Startup 方法中调用 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;
}

此版本针对的是应用程序级外接程序。 若要使用此代码,请将其粘贴到项目内的 ThisAddIn 类中,然后从 ThisAddIn_Startup 方法中调用 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;
}
