I 'd written an article [http://blog.csdn.net/wxqee/article/details/7644831] about this title. Here is the upgrade version
As c ++. It has been tested in Linux, you can just copy & Paste the source codes into your project, then simply use as following to query a text in hex style.
string str, hexstr;str = "dasjfkldjsafl; jkdfdaifeoweqrnealknf1u4908278593721";wx::TraceBin::tracebin (str, hexstr);std::cout << hexstr;
Very simple, right? Here are the source codes.
