为什么我的简单 C++ GUI应用程序显示中文消息框?

我已经在 Visual C++ 中实现了如下代码块:

I have implemented this block of code as below in Visual C++:

int nResult=MessageBox(NULL,
                       (LPCWSTR)"An example of Cancel,Retry,Continue",
                       (LPCWSTR)"Message Box!",
                        MB_ICONWARNING|MB_ABORTRETRYIGNORE);

然而，无论我尝试什么，它总是显示一个中文消息框！因此，我只想为我的问题寻求任何解决方案以及为什么这里有中文信息.谢谢！

however, no matter what i tried, it always show a message box in chinese! Therefore, i just want to ask for any solution for my problem and why there is chinese message here. Thanks you!

推荐答案

您忘记在字符串字面量之前放置 'L'.修改如下:

You forgot to place 'L' before the string literal. Modify as follows:

int nResult=MessageBox(NULL,
                   L"An example of Cancel,Retry,Continue",
                   L"Message Box!",
                   MB_ICONWARNING|MB_ABORTRETRYIGNORE);

在 C++ 中，Unicode 字符串文字以 L 为前缀.如果您不添加前缀，则转换为unicode string constant"将无济于事，并会导致对内存位置的错误解释.

In C++ unicode string literals are prefixed with L. If you don't put the prefix, casting to 'unicode string constant' won't help and causes incorrect interpreting of the memory location.
