print message to debug output window (VS)-优快云博客

本文介绍了一种在Visual Studio中调试程序的有效方法。通过使用特定格式输出信息，并调用OutputDebugString()函数，可以在输出窗口中查看并双击定位到源代码。此外，还提供了一个预处理指令示例，用于在编译时输出消息。

Some times we could want to print the debug messages to a window (console or windows) or a file, we debug our programms with these information. There's a better way to debug programm, print the message to output window if you use VS, and you can double click the message to locate the source codes. To achive this, you only need to:

1. sprintf the message to format as: __FILE__(__LINE__):message string

2. Invoke OutputDebugString() to print the message to ouput window.

Note: for c++, OutputDebugString() is for printing message into Output window; for dotnet, Debug.WriteLine() is for the same purpose.

else, you should want to print some messages to output window when compiling, yes you only need to:

1. format the message string

#define Stringize( L ) #L
#define MakeString( M, L ) M(L)
#define $Line MakeString(Stringize, __LINE__)
#define Reminder(_s_) __FILE__"("$Line"):"_s_

2. output

#pragma message(Reminder("aabbccddeeff"))
