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;
}
