I. Conversion of reference parameters and pointersStandard C does not support reference parameters, which need to be converted. The following is an example of the Destroytriplet () function in Bo1-1.cpp and bo1-1.c to illustrate this conversion.The functions that contain reference parameters in Bo1-1.cpp are as follows:1 Status destroytriplet (Triplet T) {2 /
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
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 =

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:

However, when the CPU starts working, power and clock would already be stabilized.4.Execute memory initialization sequence.5.Program memc_cmd to ' 3 ' b000 which makes DRAM Controller enter "Ready" state.6.Check Memory Status field in Memc_stat until memory status becomes ' 2 ' bo1, which means ' ready '.From the above

Null and undefined
Null indicates a "null" value. It is different from 0 and null String ''. 0 is a value,'' indicates a string with a length of 0, and null indicates "null ".

2. If there are no instances of the constructor object, go to its prototype object and find it, if any, return it;
Although we can access the values stored in the prototype through an object instance, we cannot access the values in the prototype by overriding the object instance;
