請教各位高手～
小毅遇到一個難題，這個問題在目前的討論過的問題中搜尋不到
這個問題就是 我需要在一般Users登入Windows的權限下，模擬Administrator or PowerUser登入Windows，以便執行RegAsm.exe註冊一個元件，否則RegAam.exe總是會Rise一個Access Denied的訊息！
我將MSDN的範例程式碼如下：看起來似乎可以模擬其他使用者的權限，但是在這個模擬之下叫用RegAsm.exe註冊元件依然得到 登錄檔 Access Denied的訊息
程式碼如下，Sorry 很久沒登入忘了貼Source Code的時候是要用什麼標籤包起來才會字鄧排版～容易閱讀

}對了！不知道版主有沒有遇過類似問題，希望能Share一下，先說聲謝謝～萬分的感謝
