Re: [Boost-users] Why can I not put a break in this part of asio sample code?

Thanks, Yes, you are right. I tried to compile in debug mode but I have a problem. What change is needed?

Ensure that the CRT settings are consistent for all *.cpp's. Probably, you ocasionally overriden Code-generation settings for some specific *.cpp in Debug configuration? Check Project->Properties->Configuration properties->C/C++->Code generation->Runtime library, then the same for each *.cpp.
