My program works great with windows xp. I am trying to add some more functionality and using OutputDebugString() to show some debug information. works flawlessly on XP. Now when i want to use the same program on windows 7x64. I dont see any output in DebugView.

h header defines OutputDebugString as an alias which automatically selects the ANSI or Unicode version of this function based on the definition of the UNICODE preprocessor constant.
Sorry for reviving an old question, but we spent a good couple of days searching the internet to answer this one and eventually ended up logging a connect call. I am posting here to help anyone else in the same situation. Our specific problem was getting the output from OutputDebugString, MFC TRACE etc in the debug output window when debugging an x64, mixed mode application.
According to Microsoft, apparently for debugging x64 mixed mode applications the debugger type of 'auto' (set in the Debugging->Debugger Type property page) defaults to managed rather than mixed. This will need to be explicitly set to 'Mixed' for both managed and native debug output to be seen when debugging a 64 bit build.
