A summary of COM + for VB programmers

Overview: COM + and Windows SQL Server provide a complex infrastructure for developing distributed applications. This article explains and helps you identify the key technologies you need to master to build a large-scale information system for Windows Server.

In this way, a millennium is over, and another millennium is just beginning. How much impact does this change have on your life as a career developer? Of course, when all the alarms are pointing to zero, there are always some temporary twists and turns here and there. Some antiquated systems have to be sent to where they should eventually rest. However, our industry as a whole does not experience the so-called apocalyptic scene as some media predicts. This is especially true for those of us who want to develop applications based on the operating systems and development tools that have been developed in recent decades. When you look back on all this, you will find it very funny. All the rumors that your company's information system is going to crash are obviously a big exaggeration.

So, again, do the news media really know what's going on in the industrial world? They have mistaken the fact that this is only a century-old problem, not really a millennium bug. The problem stems from the fact that we use only two characters to represent a date instead of four characters. If humans had the same technology 100 years ago, we would face the same problem on the 1899 New Year's Eve. However, the millennium bug sounds more Lshun, so more newspapers and magazines are sold.

Remember that a few years ago, the press predicted that everything would be rewritten in Java, including the American constitution and Magna Carta? Now that the buzz about Java has subsided, we look at Java as a young and promising language with its pros and cons. It did not sweep across the industry. It's just a language that works in some environments but doesn't work in other contexts.

Now, everyone is talking about XML as a technology that can save everything. I know that when XML matures, we find it more useful. It will solve many very difficult and also very realistic problems. However, XML will never replace other technologies, such as COM, Corba, and Java, as well as other technologies known to people. It is important that we hold a long-term view of all these emerging technologies. It is harmful to be overly optimistic about a new technology that can solve the problems that will be encountered in the coming years.
