跟踪到MFC应用程序中的控制台

Question

I am currently tracing my errors in an MFC application to a .log file and to the event viewer, but I would also like to trace to the console. 我目前正在将MFC应用程序中的错误跟踪到.log文件和事件查看器中，但是我也想跟踪到控制台。 A console solution is posted here: http://www.codeproject.com/Articles/612/Creating-a-console-for-your-MFC-app-s-debug-output 控制台解决方案发布在这里： http : //www.codeproject.com/Articles/612/Creating-a-console-for-your-MFC-app-s-debug-output

but I want to be able to turn it on and off easily (Perhaps with a TraceSwitch). 但我希望能够轻松打开和关闭它（也许使用TraceSwitch）。

In addition to the obvious, 除了显而易见的

<add name="LPRConsoleListener" type=System.Diagnostics.ConsoleTraceListener" />

You must put 你必须把

AllocConsole()

in your InitInstance() function before you initialize your MFC Window. 在初始化MFC窗口之前，请在InitInstance（）函数中单击。
