如何在MFC中解决未定义的intellisense标识?

我在修复此MFC uArt代码中的错误方面遇到了问题。即使我在程序中包含了一些头文件,三个intellisense也是未定义的。

这是构建和运行程序时的错误代码。

有没有人知道我include遗失了哪些标题文件?因为当我在代码中声明char sUart [60]时出现错误,并且在strcpy方法中,pBuffer LPTSTR中似乎出现错误。请帮忙。

1 个答案:

答案 0 :(得分:1)

这通常表示您正在进行Unicode构建,其中LPTSTR扩展为wchar_t *,并且您尝试将其与非Unicode字符串混合(在你的情况下是一个char数组。

而是将tmpUart定义为:

TCHAR tmpUart[60];

并使用_tcscpy复制字符串。这样,您的代码将以Unicode和非Unicode构建进行编译。
