【中文标题】在井字游戏 C++ 中使用“新游戏”按钮，win32 应用程序初学者【英文标题】：Using a "New Game" button in Tac Tac Toe C++, win32 app beginner 【发布时间】：2013-06-26 19:36:43 【问题描述】：我正在使用 C++ 制作我的第一个 win32 应用程序，一个井字游戏，到目前为止，我已经能够制作一个 3 x 3 的按钮网格，当点击这些按钮时，将根据谁打开它来显示 X 和 O是。我遇到的麻烦是弄清楚如何在游戏结束后清除所有的 X 和 O（我还没有时间让我的程序确定是否有赢家，这将在稍后出现）。
所以我制作了一个“新游戏”按钮，但我不知道如何在单击它时清除所有内容...有什么帮助吗？

很抱歉，我的组织可能很糟糕......但是代码可以编译并执行我到目前为止所解释的内容。另外我应该补充一点，我确实有头文件，我不包括这些头文件定义了您可能在此代码中看到未定义的变量。感谢您在如何使用“新游戏”按钮“重置”所有内容方面给予我任何帮助
【问题讨论】：
担心TCHARs 真的没有意义。只需在周围使用宽字符串。
我从 Visual c++ 2010 中的模板应用程序开始，然后从那里拿走了它，所以我选择不改变他们已经为我做的很多事情。但是，是的，我是全新的，所以谢谢你的建议。
【参考方案1】：
将playerobject 和所有click 全局变量重置为零，并将每个按钮的文本设置为零，例如SetDlgItemText(hWnd, IDM_LOC1, "");.
【讨论】：
谢谢！我什至没有想到这一点，这几乎太容易了....那太好了！作为记录，是否有另一种方法可以做到这一点，而无需亲自更改所有值？ 您可能会考虑使用一些数组和循环来简化编码并消除代码重复，例如int click[9];（不要忘记索引为 0-8 或忽略条目 0 并使用 int click[10];）。此外，如果您的资源标识符是连续的（IDM_LOC1...IDM_LOC9），您可以使用循环来重置文本，（for (UINT i=IDM_LOC1; i<=IDM_LOC9; i++)...）等。您还可以为按钮单击创建通用函数...
非常感谢，我将研究其中的一些想法，以使我的代码不那么混乱。以上是关于在井字游戏 C++ 中使用“新游戏”按钮，win32 应用程序初学者的主要内容，如果未能解决你的问题，请参考以下文章
