Hi, I ran into a problem when using the 2010 boost.process library within a Windows GUI application with WinMain() instead of main() without a console. When I construct a context object the std[in|out|err]_behavior members are initialized in the constructor with calls to behavior::inherit::create(GetStdHandle(...)), which calls DuplicateHandle(). DuplicateHandle() fails with error 6 (invalid handle) since the application has no console and an exception is thrown. So currently I don't see how I could use a context object from within a Windows GUI application since its constructor will always throw this exception. What I want to do is start a child process and read its stdout as in the example "Communicating with child processes". Best regards, Wolfgang
