How to share a data layer interface in COM +: Delphi/Windows SDK/API
Http://www.delphi2007.net/DelphiNetwork/html/delphi_20061216191901110.html
In COM + development, I want to build a common data service layer component consisting of a data access control such as mtsdatamodule and ADO. Each Business Object interacts with the database through it. However, when a business object accesses this data access component, an mtsdatamodule object instance is created. In this way, multiple mtsdatamodule

--- [[Basic -- simple C ++ program] ------------------------------------------
I don't want to waste time explaining the basics of C ++. If you have no idea about C ++ or object-oriented programming technology, read this book first. Before proceeding, check whether you have mastered or understood the following C ++ terms: 1. Class)2. Object)3. Method)4. Virtual)5. inherit (inheritance)6. Derivative (derived)
Next, read the following two programs and confirm that you understand the me
It is actually a very simple problem, but it is ignored in a small place.
Java does not need to overload operators, so it will automatically mount to = when equal is written.
C # needs to display overload =
Instead of override Equals, You have to wipe your ass.

In addition, the function is called in a standard C program, and A should be added before the argument.The statement called Destroytriplet () in Main1-1.cpp is1 destroytriplet (T);The corresponding standard C program main1-1.c calls the Destroytriplet () statement as1 destroytriplet (t);Where the two arguments of the Destroytriplet () are the same, the two argument T types are the same.In addition, in the conversion process, encountered * or * can be "offset", will be *t convert

simulation of the circular chain, which is accessed to the last node, the manual jump to the first node. The same is the case before accessing the first node. This can also achieve the function of the circular chain list, in the direct use of the cycle linked list is more troublesome or may have problems when you can use.

Structure Initialization Method
1. You can define and create structural variables at the same time.
struct perks{ int key_number; char car[12];}mr_smith, ms_jones;
2. You can even initialize variables created in this way.

need to start from the first node and access the next node, all the time, to the desired location. But you can also save the location of a node in advance and then access it directly. Of course, if only access to the data is not necessary, as well as the list to store pointers to the actual data. This is typically done to access the next or previous node in the linked list.Relative to the doubly linked list, this ordinary, each node has only one pointer to the linked list is also called one-way

First, I recommend that you read the difference between Equals and = before proceeding to this article (although some explanations in this article are still a bit difficult ), I wrote this article only because of the issues that have arisen in my article @ Yimu sunshine. Of course, you can also read this article directly, because I have not forcibly linked this article with it.
Let's take a look at the following code:
