推荐答案

如果您正在开发MFC应用程序，则必须输入:

If your developing an MFC application then you have to put:

#include "stdafx.h"

在源文件的顶部.

at the top of your source file.

除了您陈述的问题外，这看起来还很可疑:

In addition to your stated problem, this looks suspicious:

new WAVEHDR[ sizeof(WAVEHDR)]

您可能是
之一

You probably mean one of

(WAVEHDR*) new char[ sizeof(WAVEHDR)]

或

or

new WAVEHDR[1]

或

or

new WAVEHDR

DEBUG_NEW [

DEBUG_NEW[^] is used to help find memory allocation problems.

The easiest way to fix this is to ensure that you include afx.h in your file.

Alternatively, you will have to search for the statement #define new DEBUG_NEW in your project and delete it (don''t delete it from any system headers)
