    You can do a few things:
    1) You can use C++/CLI to integrate in with .NET, thus being able to call the managed code directly from within C++ (though your executable is then tied directly to .NET)...

    Re: istream::getline() and getline()

    You read a blank line... that blank line fills zero characters of the buffer. The get function returns 0 as the # of characters read into the sz buffer. The while loop ends because it thinks it...

    Re: istream::getline() and getline()

    I'm not quite sure what you're trying to accomplish with the first way of reading the data. You're limiting yourself to 100 characters per line, so assuming you want to append the \n character is...

  7. Re: Need a way to store and retrieve 31 Strings in a Property

    A collection of strings, either List(of string) or the likes, should work just fine. You can further restrict it by making your collection string[31] if you want.

    Re: C++ Private Inheritance

    Re: need little help with MSXML

    Look up xpath. Use xpath to search for "item/title" and "item/link" (or "/item/title" or just "title",etc. It really depends what scope you're at.)

    Check out xpath and then get back to us.

    Below is a corrected solution (untested, but I think it'll be fine).
