最近粗略的看了些移动开发的文章，才恍然大悟这个世界已经变了。当我的了解还仅限于Object-c based iOS开发和Java-based Andriod native app的开发方式时，HTML5原来早就已经入侵移动开发领域了。最近有个叫PhoneGap的东东被Adobe收购了。我研究了一下，最终理解了：PhoneGap是纯用HTML5+CSS3+Javascript来开发的，然后，它很聪明的还是基于native app的SDK的方式（as wrapper）wrap成native app的样子，从而可以在appstore和android market上发布——一份代码，到处运行！Adob 阅读全文

1. 什么是rValue？lValue呢？rValue主要是指没有名字的变量（即临时变量/对象）；lValue主要是指有名字的变量。除了lValue都是rValue（废话）。下面的例子可以比较直观的帮助理解：int&& n = 42; // OK; 42 is an rvalue; n is rvalue reference.int k = n; // OK; n is rValue reference and is lValue.int&& j = k; // Error; k is an lvalueint&& m = k+1; // OK, 阅读全文

0. Stack unwinding.When an exception is thrown and control passes from a try block to a handler, the C++ run time calls destructors for all automatic objects constructed since the beginning of the try block. This process is called stack unwinding.Two notes: 1) local objects will be destructed in re. 阅读全文

根据effective STL的rule，从效率和正确性角度考虑，使用STL的算法要比自己写循环遍历要effective。之前一直没讲究过这个。从现在起，要注意起来了。先学起来下面三个1. find2. find_if 3. for_each它们都会用到mem_fun, mem_fun1(可以接受一个参数),bind2nd(ptr_fun(funcName), argument)。详见下面的例子（来自：http://www.builder.com.cn/2008/0129/723326.shtml） 比如我们有下面的类： classClxECS{public:intDoSomething(). 阅读全文

今天看了一点QT相关的代码，想要弄明白client application中QCanvas的derived class（那里是获取事件信息的源头）是何时被创建并注入到QT中去的。顺便了解了些QT信号和槽的知识。note down:1. 首先，QT signal 和slot都是QT自定义的东西，非C++所有。那么包含有这些玩意的h和cpp文件是如何编译的呢？分下面几步：1）调用QT自家的moc编译工具对这些玩意进行解析进而生成标准c++编译器支持的代码。 （A.h/cpp） -> (A.moc.h/cpp)2）把A.moc.h/cpp交给C++编译器进行编译。More:元对象编译器 moc 阅读全文

In debugging, it's always annoying to step into CString like classes as in most cases we don't need to get into there. There does exist solution to NoStepInto functions/classes you don't intend to step into:1. Ahead of VS20101) Look into this article to add something into Registry: How t 阅读全文

Two ways to make use of it:1) directly declare a function pointer variable at the place where it's required. like below:void (*pFunc)(int); // pFunc is a variable herepFunc = &FuncA;pFunc(2);2) typedef a function poiner type and then use it. like below:typedef void (*pFunc)(int);pFunc pFuncO 阅读全文
