hresult

I know the VC++6.0 is very old language, but i don't have a choice, i am just maintaining an existing program, and i encounter this error Unhandled exception in Assess.exe (KERNELBASE.DLL): 0xE06D7363: Microsoft C++ Exception And here is my code HRESULT hr = CoInitialize(NULL); // Create the interface pointer. IModulePtr pI(__uuidof(RPTAModuleInterface)); //the error is here After debugging and using f11 the program goes to COMIP.H and here is the code explicit _com_ptr_t(const CLSID& clsid, IUnknown* pOuter = NULL, DWORD dwClsContext = CLSCTX_ALL) throw(_com_error) : m_pInterface(NULL) {

I know the HRESULT_FROM_WIN32 macro to convert a Win32 error code into an HRESULT, is there any way to do the conversion starting from an errno error? In short, no. As of http://msdn.microsoft.com/en-us/library/5814770t%28v=vs.100%29.aspx The errno values are constants assigned to errno in the event of various error conditions. ERRNO.H contains the definitions of the errno values. However, not all the definitions given in ERRNO.H are used in 32-bit Windows operating systems. Some of the values in ERRNO.H are present to maintain compatibility with the UNIX family of operating systems. The errno

I am doing some exception handling for code which is writing to the StandardInput stream of a Process object. The Process is kind of like the unix head command; it reads only part of it's input stream. When the process dies, the writing thread fails with: IOException The pipe has been ended. (Exception from HRESULT: 0x8007006D) I would like to catch this exception and let it fail gracefully, since this is expected behavior. However, it's not obvious to me how this can robustly be distinguished from other IOExceptions. I could use message, but it's my understanding that these are localized and
