The associated COM server does not support ActiveX Document embedding

winfrom 通過dsoframer實現讀取excel文件報錯：

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 ---

解決方法：

Open時把第三個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)
    打開文檔，可以是本地文件或者是服務器文件
參數：
Document  文檔路徑
ReadOnly  是否已只讀模式打開
ProgId    OLE類型
WebUsername  用戶名（訪問網絡的文件時候，有可能需要）
WebPassword  密碼
例子：

axFramerControl1.Open(sPath, true, "Excel.Sheet", "", "");//
DsoFramer1.Open "C:\TestBook.xls"
DsoFramer1.Open "C:\Plain.txt", , "Word.Document"  //用Word來打開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"
