std::exception's constructors
I have an exception class to which I added another constructor. These are the existing and the added ones: 1) Existing: Exception::Exception(const std::string& err_msg /* other parameters */); 2) Added: Exception(const std::exception& except /* same other parameters */); The following 'throw' caused am... 1 Sep 2006 13:21

I'm having a hard time distilling out of all this information how to do the following most-basic task: I want to map a file into my process address space and get two unsigned char *, one to the very fi... 1 Sep 2006 00:34

C2124 is most disrespectful of IEEE floating point arithmetic
Since VC++ purports to follow IEC 559, and IEC 559 defines the division of a non-zero by a zero to be a signed infinity, isn't it rather silly that: float inf(1.0f / 0.0f); should result in a compile-time error, C2124? An error may be appropriate for integer arithmetic (as it'll generate a runtime SEH except... 13 Sep 2006 13:13

Using enums from other libraries as defaultvalues
Hello newsgroup, I want to use the enum values of a third-party type library as defaultvalues for my own interface. Unfortunately, this seems not to work. The code for the test looks like this: [ uuid(6A7B3B27-AE89-4255-8BEF-8B937FDD788B), version(1.0) ] library TestBaseLibrary { importlib("stdole3... 21 Aug 2006 06:30
