使用XPCOM註冊dll文件時，我可以獲取界面，但無法獲得類！

我有成功的安裝我的dll文件雷鳥。但在我XPCOMViewer我只能找到接口而不是類，所以，當我使用的組件，它顯示了我的錯誤：類型錯誤：Components.classes [CID]是不確定的使用XPCOM註冊dll文件時，我可以獲取界面，但無法獲得類！

尊敬的大家，

我已成功安裝我的dll文件到雷鳥。但在我XPCOMViewer我只能找到接口而不是類，所以，當我使用的組件，它顯示了我的錯誤：類型錯誤：Components.classes [CID]是不確定的

你所說的「安裝」是什麼意思？ – Neil 2011-04-05 23:20:28

TypeError: Components.classes[cid] is undefined

這表明你的組件安裝不正確。

這裏的步驟，以在FF 3.6

複製.dll和.xpt文件安裝新的XPCOM組件到<的％ProgramFiles％\ Mozilla Firefox的\組件>目錄
在％ProgramFiles％\ Mozilla Firefox \ components目錄中，有一個名爲「componets.list」的文件。只需在您的DLL文件的添加名稱，這將迫使註冊
現在firefox.exe盯着之前，從您的個人資料目錄中刪除的compreg.dat和xpti.dat文件。

啓動Firefox現在和你的組件必須自動註冊。

這是做的手工方式，這將是更好地包裝在一個XPI文件擴展名和分發，因爲不是每個人都希望有這樣的文件撥弄。 – 2012-01-14 17:36:06

添加到您的install.rdf，根據描述部分：

<em:unpack>true</em:unpack>

如：

<Description about="urn:mozilla:install-manifest"> 
    <em:id>[email protected]</em:id> 
    <em:version>1.0</em:version> 
    <em:type>2</em:type> 
    <em:unpack>true</em:unpack> 
    ...

這是因爲XPCOM的二進制文件要求進行解包是可用見文件： https://developer.mozilla.org/en/Install_Manifests

下解壓。
