我想使用 TRACE() 宏在 Visual Studio 的调试窗口中获取输出;2005 在一个非MFC C++ 项目中,但附加的头文件或库是需要吗?
I want to use the TRACE() macro to get output in the debug window in Visual Studio 2005 in a non-MFC C++ project, but which additional header or library is needed?
有没有办法在调试输出窗口中放置消息,我该怎么做?
Is there a way of putting messages in the debug output window and how can I do that?
构建您自己的方案.
trace.cpp:
#ifdef _DEBUG
bool _trace(TCHAR *format, ...)
{
TCHAR buffer[1000];
va_list argptr;
va_start(argptr, format);
wvsprintf(buffer, format, argptr);
va_end(argptr);
OutputDebugString(buffer);
return true;
}
#endif
trace.h:
#include <windows.h>
#ifdef _DEBUG
bool _trace(TCHAR *format, ...);
#define TRACE _trace
#else
#define TRACE false && _trace
#endif
然后只需 #include "trace.h" 就可以了.
then just #include "trace.h" and you're all set.
