Just what is a regular expression, anyway? Take the tutorial to get the long answer. The short answer is that a regular expression is a compact way of describing complex patterns in texts. You can use them to search for patterns and, once found, to modify the patterns in complex ways. You can also use them to launch programmatic actions that depend on patterns. A tongue-in-cheek comment by programmers is worth thinking about: "Sometimes you have a programming problem and it seems like the best solution is to use regular expressions now you have two problems." Regular expressions are amazingly powerful and deeply expressive. That is the very reason writing them is just as error-prone as writing any other complex programming code. It is always better to solve a genuinely simple problem in a simple way when you go beyond simple, think about regular expressions. Tutorial: Using regular expressions

多项式曲线拟合 任意介数 Purpose - Least-squares curve fit of arbitrary order working in C++ Builder 2007 as a template class, using vector<FloatType> parameters. Added a method to handle some EMathError exceptions. If do NOT want to use this just call PolyFit2 directly. usage: Call PolyFit by something like this. CPolyFit<double> PolyFitObj double correlation_coefficiant = PolyFitObj.PolyFit(X, Y, A) where X and Y are vectors of doubles which must have the same size and A is a vector of doubles which must be the same size as the number of coefficients required. returns: The correlation coefficient or -1 on failure. produces: A vector (A) which holds the coefficients.

Siproxd is a proxy/masquerading daemon for the SIP protocol. It handles registrations of SIP clients on a private IP network and performs rewriting of the SIP message bodies to make SIP connections work via an masquerading firewall (NAT). It allows SIP software clients (like kphone, linphone) or SIP hardware clients (Voice over IP phones which are SIP-compatible, such as those from Cisco, Grandstream or Snom) to work behind an IP masquerading firewall or NAT router

Please unzip the file and make the file under linux with version 2.6 or above. The function is just like the utility traceroute in linux or tracert in windows.

These listed libraries are written in WTL. But it s really hard to mix both MFC & WTL together. Obviously, it s not reasonable to ask a developer or a team to giving up MFC and move to the WTL world just because there were some great controls or visual Frameworks written in WTL (there are many things that should be considered especially in a company with hundreds of developers like the company I work for). Unfortunately, there was no such good and free visual Framework in MFC until now. Whatever difficulties there are, I still desire to be able to use them and now my effort is here to be shared with you. Under the Hood

Expert C Programming: Deep C Secrets By Peter van der Linden. Have you ever noticed that there are plenty of C books with suggestive names like C Traps and Pitfalls, or The C Puzzle Book, or Obfuscated C and Other Mysteries, but other programming languages don t have books like that? There s a very good reason for this!
