问题描述

我有一个MDI应用程序.该MDI应用程序还有许多其他工具，包括编辑器.我想用我的MDI应用程序的编辑器打开所有".txt"文件，从而使我的应用程序成为所有".txt"文件的默认查看器.

I have a MDI application. This MDI application has lots of other tools including an editor as well. I would like to open all the ".txt" files with the editor of my MDI application, thereby making my application as the default viewer of all the ".txt" files.

无论何时用户编辑".txt"文件，MDI应用程序都应启动，并在编辑器窗口中填充所选".txt"文件的内容.

Whenever the user edits a ".txt" File the MDI application should launch and a editor window should be populated with the contents of the chosen ".txt" file .

请问有什么方法可以做到这一点.

Is there a way I can do that please.

谢谢

推荐答案

您需要更改此注册表项:

You need to change this reg key:

HKCR\txtfile\shell\open\command

将默认值更改为您的程序，并在参数末尾添加％1.然后在程序中处理命令行args，以执行所需的操作.

Change the default value to your program with %1 at the end for parameters. Then in your program handle the command line args to do what you want with it.
