    Re: XML Parsing

    Who knows what could be "the best" for you? :confused:
    However, it is pretty easy to use. Just try the XmlLite Samples:
    Read an XML Document using XmlLite

    Err...!!!!

    Please, compare your "code" with mine:

    Don't you see a difference?
  18. Re: Using one thread at a time with CSemaphore problem

    It is almost correct.
    Note, however, that PostMessage could fail. In such a case you would have the memory leak.
    To prevent it just write

    CSt!ring * s = new CString("listitem");...
  19. Re: Using one thread at a time with CSemaphore problem

    I already gave you a link in the post#2 (and then I mentioned it again in the post#14) in your another thread.

    Re: MYSQL VC++ Connection Dealy

    (Almost) all is possible.
    Why do you open Dialog 2 immediately? Open it after you have read the password!
