registry - 如何正确地将文件关联添加到 Windows 注册表？

Question

我应该将哪些数据和位置添加到 Windows 注册表中以正确创建文件关联？

我问这个问题主要是因为我多年前编写的一些旧应用程序使用 Visual Studio .NET 的 Windows Installer 打包程序来创建文件关联。我安装的扩展是 .whr和 .encxml .

现在，在安装了这些应用程序的计算机上，有时会出现一个奇怪的问题——在 Google Chrome 或 Internet Explorer 中下载文件(尤其是 exe、msi 或 zip 文件)时，浏览器会将文件扩展名更改为 1我的安装程序安装的扩展程序。我不知道它是否会影响其他浏览器——这两者有什么共同之处吗？所以...如果你下载，例如，http://example.com/downloads/application.exe ，文件将被下载为 http://example.com.downloads/application.encxml (或 .whr，无论它现在选择哪个)，没有任何明显的原因。

我要注意的是 HKCR\.whr 的键和 HCKR\.encxml key 引用(客户经理加密的 XML 文件和工作时间记录)中有空格，当我在 Visual Studio 中创建关联时，我没有添加“。”到前面。也许不允许使用空格，和/或您应该以“.”为前缀？注册表代码似乎没问题，但我通过查看我的注册表注意到，每个其他应用程序都不会使用关联类中的空格，而且我知道的任何机器上安装的任何应用程序的任何其他文件扩展名也不会发生此问题 - 仅由我的应用程序的 VS 安装程序创建的那些。我已经粘贴了与文件扩展名相关的相应注册表项和值的注册表转储 - 由于 MSI 是专有的，我不知道这是否是全部，但根据我从其他应用程序中了解到的情况，这应该是全部。多年来，我一直想知道这个问题，但一直想不通。我很快就会用更新的产品替换那些旧应用程序之一，所以这次我想确保没有像这样的奇怪错误......

Answer 1

在 Windows Installer 中，我们使用 RegisterExtensionInfo 标准操作:

其中使用主要使用扩展和动词表以及与 COM 相关表的一些连接:
