winfrom 通过dsoframer实现读取excel文件报错：
System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation. ---> System.Runtime.InteropServices.COMException (0x80041103): The associated COM server does not support ActiveX Document embedding.
at DSOFramer._FramerControl.Open(Object Document, Object ReadOnly, Object ProgId, Object WebUsername, Object WebPassword)
--- End of inner exception stack trace ---
解决方法：
Open时把第三个progID加上就可以，
2. HRESULT Open([in] VARIANT Document, [in, optional] VARIANT ReadOnly,
[in, optional] VARIANT ProgId, [in, optional] VARIANT WebUsername, [in, optional] VARIANT WebPassword)
打开文档，可以是本地文件或者是服务器文件
参数：
Document 文档路径
ReadOnly 是否已只读模式打开
ProgId OLE类型
WebUsername 用户名（访问网络的文件时候，有可能需要）
WebPassword 密码
例子：
axFramerControl1.Open(sPath, true, "Excel.Sheet", "", "");//
DsoFramer1.Open "C:\TestBook.xls"
DsoFramer1.Open "C:\Plain.txt", , "Word.Document" //用Word来打开c:\plain.txt文件
DsoFramer1.Open "https://secureserver/test/mytest.asp?id=123", True, "Excel.Sheet", "MyUserAccount", "MyPassword"
3.HRESULT Save([in, optional] VARIANT SaveAsDocument, [in, optional] VARIANT OverwriteExisting,
[in, optional] VARIANT WebUsername, [in, optional] VARIANT WebPassword);
保存文件在本地
DsoFramer1.Save "c:\1.doc"
