visual-studio-2008 - no output tracing appears in Visual studio output window

Question

i have been using several ways to Trace output inside Visual Studio 2008 output window but with no mean, i tried:

   `cout<<"AAAAAAABBBBBBBBBB";

LPCWSTR str=_T("jdhakjsdk");
OutputDebugString(str);

printf("jdhakjshkajshdkjashdk");`

but nothing appears!! is it true that the output window might be locked??

Answer 1

不知道为什么你没有得到调试输出（请记住，它OutputDebugString只能在调试模式下工作，并附有调试器）。但是，在 MFC 中，您通常使用TRACE宏：

TRACE(_T("Data: %s\n"), pszData);
