如何在自己的应用程序中像“探索"中那样创建“打开方式"列表 [英] How can I create a “Open with” list as in Explore in my own application

问题描述

在我的应用程序中，用户可以选择对文件的引用，例如图像文件.我想使用带有箭头的按钮来打开一个列表，其中包含安装在系统上的程序，巫婆可以打开此文件类型.

In my application the user can select reference to file, for example a image file. I would like to make button with a arrow that opens a list with the programs installed on the system witch can open this file type.

我知道我可以从注册表"HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer \ FileExts"中获取程序名称，但是如何过滤出没有意义的条目-"DllHost.exe，miaui.exe等."以及如何使用用户选择的程序打开文件?

I know that I can get the program names from the registry "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts", but how can I filter the entries out that have no meaning - "DllHost.exe, miaui.exe, etc." And how can I open the file with program that the user choose?

@ Lars Tech如果我在注册表"HKEY_CURRENT_USER \ Software \ Microsoft \ Windows \ CurrentVersion \ Explorer \ FileExts \"中查找，然后在扩展名".jpg"中查找"OpenWithList"，则将看到更多条目，如果使用rigt单击jpg文件，然后选择打开方式"(请参阅​​我的第一张图片)，我只想要那些.是的，我已经正确添加了程序的条目，但这些条目对jpg文件没有任何意义.Windows可以将它们过滤掉，我也可以.

@ Lars Tech If I look in registry "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\" and then "OpenWithList" for the extension ".jpg" I see more entries that if if rigt click on jpg file and choose Open With ( see my first images) and I only want those. And yes there is program's entries that I properly self have added, but that have no meaning to a jpg file. And Windows can filter them out so will I.
