问题描述

我怎样才能确保当我转移扫雷时它会是 unicode 而不是被转换为 ASCII?

HWND procHnd;
HWND windowHnd=FindWindow(NULL,"Minesweeper");

进程或窗口表示的名称是否重要?

推荐答案

您可以显式使用 Unicode 版本的 API

You can explicitly use the Unicode version of the API

HWND windowHnd = FindWindowW(NULL, L"Minesweeper");

您目前正在为 ANSI 字符构建应用程序.如果您想在整个过程中使用 Unicode，您应该更改您的项目选项以使用 Unicode.如果你这样做了，你可以简单地把它写成

You are currently building your application for ANSI characters. If you want to use Unicode throughout you should change your project options to use Unicode. If you did that you can simply write it as

HWND windowHnd = FindWindow(NULL, L"Minesweeper");

具有包含文本的参数的 Windows API 函数有两个版本，即 ANSI 版本和 Unicode 版本.例如，user32 DLL 不导出名为FindWindow 的函数.相反，它导出 FindWindowA(ANSI 版本)和 FindWindowW(Unicode 版本).Windows 头文件中的宏将 FindWindow 转换为 FindWindowA 或 FindWindowW，具体取决于您的目标字符集.

Windows API functions that have parameters which contain text are available in two versions, an ANSI version and a Unicode version. For example the user32 DLL does not export a function called FindWindow. Instead it exports FindWindowA, the ANSI version, and FindWindowW, the Unicode version. Macros in the Windows header files convert FindWindow into either FindWindowA or FindWindowW, depending on which character set you target.

在 Visual Studio 中，您可以在 Configuration Properties | 下的项目配置中设置此选项.一般 |字符集.选择使用 Unicode 字符集.

In Visual Studio you can set this option in the project configuration under Configuration Properties | General | Character Set. Select Use Unicode Character Set.
