将MFC应用程序分段转换为Unicode / MBCS [英] Piecewise conversion of an MFC app to Unicode/MBCS

问题描述

我有一个大的MFC应用程序，我扩展允许多语言输入。目前我需要允许用户在单个对话框中的编辑框中输入Unicode数据。

有一种方法可以不打开UNICODE或MBCS整个应用程序？我只需要转换应用程序的一小部分。

---

澄清：如果是这样，我可以使用:: GetWindowTextW（）获取Unicode信息出窗口。我想弄清楚如何允许用户在窗口中输入Unicode文本。目前，Windows-1252代码页外的字符用户类型显示为？。是否有解决方法？

解决方案

允许 CEdit 显示Unicode字符，您应该使用 CreateWindowW 函数创建它。我已经在ANSI MFC程序中测试了它。

  //允许Unicode字符
 CreateWindowW（LEDIT ，L，WS_CHILD | WS_VISIBLE，10，10，50，20，GetSafeHwnd（），0，0，0）; 
 
 //显示Unicode字符？ 
 CreateWindow（EDIT，，WS_CHILD | WS_VISIBLE，10，10，50，20，GetSafeHwnd（），0，0，0）; 
 

您可以在 OnInitDialog 对话框的功能。然后将其子类化为具有Unicode支持的自定义CMyEdit类。

I have a large MFC application that I am extending to allow for multi-lingual input. At the moment I need to allow the user to enter Unicode data in edit boxes on a single dialog.

Is there a way to do this without turning UNICODE or MBCS on for the entire application? I only need a small part of the application converted at the moment. Is it possible to do this piecewise, and if so, how?

Clarification: I could use ::GetWindowTextW() to get Unicode information out of the window. I am trying to figure out how to allow the user to enter Unicode text in the window. Currently, characters the user types outside of the windows-1252 codepage show up as '?'. Is there a way to fix this?

解决方案

To allow CEdit to show Unicode characters you should create it with CreateWindowW function. I've just tested it in ANSI MFC program.

// allows Unicode characters
CreateWindowW( L"EDIT", L"", WS_CHILD|WS_VISIBLE, 10, 10, 50, 20, GetSafeHwnd(), 0, 0, 0 );

// shows Unicode characters as ?
CreateWindow( "EDIT", "", WS_CHILD|WS_VISIBLE, 10, 10, 50, 20, GetSafeHwnd(), 0, 0, 0 );

You could create all edit boxes manually in OnInitDialog function of dialog box. And later subclass them to custom CMyEdit class with Unicode support.
