如何正確添加文件關聯到Windows註冊表？

Question

我應該將哪些數據添加到Windows註冊表中以正確創建文件關聯？

我問這個問題主要是因爲我幾年前編寫的一些舊應用程序，它們使用Visual Studio .NET的Windows Installer打包程序來創建文件關聯。我安裝的擴展是.whr和.encxml。

現在，在安裝了這些應用程序的計算機上，出現了一個奇怪的問題有時 - 當在谷歌瀏覽器或Internet Explorer（特別是exe，msi或zip文件）中下載文件時，瀏覽器將將文件擴展名更改爲由我的安裝程序安裝的其中一個擴展名。我不知道它是否影響其他瀏覽器 - 這兩個有什麼共同點？所以......如果你下載了，例如，http://example.com/downloads/application.exe，那麼這個文件將被下載爲http://example.com.downloads/application.encxml（或者.whr，無論哪一個選擇哪一個），因爲沒有任何明顯的原因。

我應該注意的是，HKCR\.whr和HCKR\.encxml鍵引用（客戶經理加密的XML文件和工作時間記錄）有空格他們，當我在Visual Studio中創建的協會，我沒加一」的關鍵。 「到前面。也許空格不允許，和/或你應該以「。」作爲前綴？註冊表代碼似乎沒問題，但通過查看註冊表，我發現每個其他應用程序都不會在關聯類中使用空間，也不會在任何已知的計算機上安裝任何應用程序的其他文件擴展名時發生此問題 - 只有由我的應用程序的VS安裝程序創建的。我已經粘貼了相應的註冊表項和與文件擴展名相關的值的註冊表轉儲 - 因爲MSI是專有的，我不知道這是否全是它，但是從我從其他應用程序知道的這應該是一切。多年來，我一直在想這個問題，但永遠不會想出來。我很快就用新產品替換了那些舊應用程序之一，所以這次我想確保沒有像這樣的奇怪的錯誤...

在Windows安裝程序，我們使用RegisterExtensionInfo標準動作：

它使用主要使用擴展和動詞表以及一些連接到COM相關表：
