In. NET 1.0 and 1.1, there are two simple methods to implement interoperability between parent and child windows.First, define a static member in the main form class to save the current main form object, for example:
Public
Static
Base:It is used to implement access to the public or protected members of the base class in a derived class, but is limited to constructors, instance methods, and instance attribute accessors.The specific features summarized in msdn include:(1) Call
Inheritance reflects the relationship between classes.
Many things in the world share commonalities. The common part is abstracted as the base class for deriving other classes, which improvesCodeThe reusability makes the code structure clear and
Definition of virtual functions:
A virtual function must be a non-static member function (and a non-constructor) of the class. Its access permission can be defined as private or proteceted, but it is meaningless for polymorphism .), Define the

I think the reason why many c programmers are reluctant to learn Java is that Java does not support pointers, but now C #, similar to Java, supports pointers, you can use
DLL injection in C #
In fact, DLL injection is very simple. It is nothing more than calling APIs such as virtualallocex, writeprocessmemory, OpenProcess, and createremotethread. Because I learned C #, I also want to take a look at the article C,
I saw a brother's article in the morning. I had a hard time trying to access different types of databases without modifying the code and implement the factory mode on my own. The spirit is commendable, but it is unknown that C # has made a factory
Recently, there have not been many things in the company. We have implemented a simple function, which is a demo. The function is extremely simple and we often encounter it.
A prompt box is displayed in the lower right corner of the gradient, which
1. Standard input/output stream of C ++
C ++ provides a set of input and output stream objects, which are Cin, cout, and cerr. They correspond to three file pointers in C language, stdin, stdout, and stderr, respectively pointing to terminal input,
I took the free time to read the course "C #2.0 sharp experience-Miscellaneous technology, and future development of C # Language" taught by Li Jianzhong. Some small knowledge points are reviewed and summarized. Here are the key points.

Bubble Sorting [bubblesort]
I. Basic Ideas
Compare the size of the elements to be sorted. If the two data elements are in the opposite order, they are exchanged until there is no reverse order of the data elements.
II. Sorting Process
Imagine the

Each language system provides a class library for Io operations to perform input and output operations on predefined types of data. The same is true for C ++, which is implemented in the form of byte streams. During the input operation, the byte

Take C ++ as a new language learning (it has nothing to do with C! True .);
Read thinking in C ++ and do not read c ++ as a dead object.
Read "the C ++ Programming Language" and "inside the C ++ object
