**：
使用atl嚮導的話，會在resource中產生乙個rgs的註冊指令碼檔案放在"registry"目錄中用來註冊元件,會在程式中通過函式declare_registry_resourceid(idr_opcserver)使用,idr_opcserver就是嚮導產生的資源檔案的id，當伺服器呼叫ccommodule::registerserver()時，便會使用這些指令碼來載入登錄檔的設定，並在呼叫ccommodule::unregisterserver()時移除它們。所有com的註冊鍵都放在hkey_classes_root中。
例子如下
hkcr 表示登錄檔中com物件的註冊項是hkey_class_root 的縮寫
noremove表示在反註冊過程中不要刪除這層登錄檔項；forceremove表示要要完全刪除後面的項然後重新建立。msdn原文如下
string literal
description
forceremove
completely remove the following key (if it exists) and then recreate it.
noremove
do not remove the following key during unregister.
val
the followingis actually a named value.
delete
delete the following key during register.
s
the following value is a string.
d
the following value is adword.
註冊後的登錄檔主要修改如下

ATL中的RGS檔案介紹
vc的atl嚮導會生成com物件註冊用的rgs檔案。如果程式中有想寫到登錄檔中的地方，可以手工編輯這個指令碼，可以省去呼叫一堆操作登錄檔的api。關於rgs的詳細規則，msdn上面有，搜尋atl registrar這個主題即可以看到，下面只是一點簡單的介紹 hkcr 表示下面的登錄檔項都寫到hkcr...
