1、下載owc11 COM組件
http://www.microsoft.com/downloads/details.aspx?FamilyID=7287252c-402e-4f72-97a5-e0fd290d4b76displaylang=en
2、註冊owc11
在工程中添加 C:\Program Files\Common Files\Microsoft Shared\Web Components\11 文件下的owc11.dll引用 或者按如下圖所以添加com
3、在工程中添加
using OWC11;
4、開始coding 舉例如下：
public class ChartFactory
{
public ChartFactory()
{
