afxDump does anything

[hankgao0703]

When I try to use MFC predefined variable afxDump which is of type CDumpContext, I can not get anything from it, but it supposes to dump output to default debugger, which in VC6.0 environment is the debug window.

Does anybody know the reason?

Thanks

post a sample of your code that does not work. If you get any complile or runtime errors post the error message as well. This should work if _DEBUG is defined:

afxDump << &quot;This is a test\n&quot;;

Thanks for reply.

I just want to test afxDump, so I created a console project with MFC support, in my main function, I just put the following line:
afxDump << &quot;Messages&quot;;
and I can not find the anything in the debug window.

The project was built with Win32 Debug configuration, so _DEBUg should be defined.

By the way, I also tried the following code:
....
CFile fhDump;
fhDump.Open(&quot;c:/dump.txt&quot;,CFile::modeCreate|CFile::modeWrite);
CDumpContext dc(&fhDump);
dc << &quot;What are you doing?\n&quot;;
dc.Flush();
fhDump.Close();
...

After executing the above code, I opened the dump.txt file, and I found nothing in it.

Gao,

I have no idea why afxDump << &quot;Testing\n&quot;; does not work for you I have a MFC console application and in my &quot;main&quot; function it works just as it is supposed to. I can't think of anything else i could suggest to you.
