Dear boost experts. We are using boost::exception in a project of ours, and are trying to extract some information from an exception to display to the user. For example, diagnostic_information(e) returns this: d:\projects\<project>\ClassName.cpp(376): Throw in function void __thiscall ClassName::CInetExceptionHandler<struct ClassName::BadLoginException>(class CInternetException *) const Dynamic exception type: class boost::exception_detail::clone_impl<struct ClassName::BadLoginException> std::exception::what: Unknown exception [struct tag_implementation_ClassName_SpecificInfo_errstr *] = Error: 12014 Context: 0 Message: The password was not allowed [struct tag_interface_CDataInterface_errstr *] = ClassName reports: Bad FTP login What I want is to extract "Error: 12014 Context: 0 Message: The password was not allowed" or "ClassName reports: Bad FTP login" from that exception. However, these exceptions may be generated in DLLs that the main program know nothing about. To simplify, here is what I do and want ot be happening: 1. Main program calls method in DLL 2. Main program knows this method can throw expections of type boost::exception 3. Main program catches such exception 4. Main program obtains string that is user-friendly from this exception Has anyone acccomplished this or knows how to extract the information from above (ideally not by parsing the string?) Alternatively, could I somehow fill the std::exception::what and then get that information out of boost::exception somehow? Thanks everyone!
