Qing Dujun Address: http://blog.csdn.net/qingdujun/article/details/35263857 In MFC, a class requires a member variable value of another class object, which requires obtaining the pointer of the original class object. In fact, there are several

A question was encountered in a written question: Ask what the output is. Come back to try, but do not know the principle, experts please advise. Packagedemo.test;//Parent ClassclassParentClass { Public inti = 0; Public voidTest ()

After exploring the memory layout of the C-style data structure, the memory layout of C + + style data structure is explored.Although the simplest class does not have any member variables and member functions, it is not worth exploring because it

Summary of the use of C + + static member variables and static member functions: one. Static member Variable:A data member in a class body is preceded by a static keyword, and the data member becomes a statically data member of the class. As with

Because you want to use the modeless dialog box to do the tool panel, you need the child box to call the parent box member variables and member functions.Previously used to send a message scheme, the same time trial parent pointer method was not

Local variables: 1. Local variables defined in local scope 2. Local variables are defined on the stack 3. Local variables have default values 4. Local variables exist with the zone in which they belong and disappear when the zone is closed.
