TEXT（）函数有什么作用？ [英] what does TEXT() function do?

问题描述

大家好。我在我的代码中使用了TEXT（）函数：

hi everybody. i have used TEXT() function in my code in such a way:

TEXT("some text")

将char *转换为wchar_t。

有没有将常量字符串替换为变量的方法？

to convert a char* to wchar_t.
is there any way to replace the constant string to a variable?

char *cAdress=NULL;
cAdress = (char *)alloca(aAdress.size() + 1);
memcpy(cAdress, aAdress.c_str(), aAdress.size() + 1);
TEXT(cAdress);

推荐答案

如果需要将文本从ASCII转换为Unicode（并且反之亦然）在你的程序中你需要使用所描述的适当的转换函数在此MSDN部分 [ ^ ]。

If you need to convert text from ASCII to Unicode (and vice versa) within your program then you need to use the appropriate conversion functions as described in this MSDN section[^].

在编译期间由预处理程序指令定义UNICODE时，将字符串标识为Unicode。否则，宏将字符串标识为ANSI字符串。

请看这里： http://msdn.microsoft.com/en-us/library/windows/desktop/dd374074%28v=vs.85%29.aspx [<一个href =http://msdn.microsoft.com/en-us/library/windows/desktop/dd374074%28v=vs.85%29.aspxtarget =_ blanktitle =New Window> ^ ]



此处讨论了类似的问题：将char *转换为wchar * [ ^ ]

Identifies a string as Unicode when UNICODE is defined by a preprocessor directive during compilation. Otherwise, the macro identifies a string as an ANSI string.

A similar question has been discussed here:Convert char * to wchar*[^]

我认为它是一个MACRO，而不是一个功能。



它如果项目是unicode，将字符串文字转换（识别）为unicode，如果项目不是unicode，字符串将保持不变



看看在MSDN文档中（http：// m sdn.microsoft.com/en-us/library/windows/desktop/dd374074(v=vs.85).aspx)



例如，它会让你将普通的ANSI字符串传递给接收unicode字符串的函数。

I think it is a MACRO, not a function.

It will convert ("identify") a string literal to unicode if the project is unicode, if the project is not unicode, the string will stay the same

Have a look at the MSDN documentation ( http://msdn.microsoft.com/en-us/library/windows/desktop/dd374074(v=vs.85).aspx)

for example, It will let you pass a normal ANSI string to a function that receives a unicode string.
