ActiveX networked multimedia object technology advocated by Microsoft
First, the origin of ActiveX
ActiveX was originally a brand name, and the technologies it covers are not isolated. it
Most of them are related to the Internet and the Web. More importantly, the whole technology of ActiveX is composed of
Microsoft's COM (Component Object Model). But don't get me wrong.
For ActiveX, all technologies including COM are defined. COM and Microsoft Office and Windows
And everything that Microsoft is doing now, but obviously these products are not in the ActiveX family.
Members of.
ActiveX is developed from compound document technology of Microsoft-OLE. Original released version of OLE
, only for compound document, but in the later version of OLE2, COM was imported. COM is for the needs of OLE designers.
Began to be born. Its basic starting point is to let one software pass through the common mechanism of another software.
Provide services. So the first user of COM is OLE2. Actually, there is no communication between COM and compound document.
How important it is. Later, COM, as a technology completely unrelated to compound document, began to be widely used. such
As soon as it came, Microsoft began to "get its hands on" common platform technology. But COM is not a product, it needs a trademark.
Name. Unfortunately, market experts chose "OLE" as the brand name. Therefore, all technologies that use COM are open.
At first, it was marked as OLE. Of course, most of these technologies have nothing to do with compound document.
Microsoft wants to explain to people: "OLE is not just compound document!" This requires considerable energy and effort.
Time.
So, in the spring of 1996, Microsoft changed its mind and chose ActiveX as its new brand name.
ActiveX refers to a loosely defined collection of technologies based on COM, while OLE still refers only to compound document. of course，
The most important core is COM.
It is a very novel idea to make the object model completely independent of the programming language. Objects from C++ and Java
In fact, we can learn something about it. But what is the so-called COM object? To make it easier to understand, you can put COM
Think of it as some kind of packaging technology, that is, think of it as different parts of manufacturing software. According to some aspects,
Object, combined into an interactive process and a set of supporting libraries. COM objects can be written in C++, Java and
VB and other languages, and can be realized in the form of DLL, can also be used as the execution file of different processes.
Now Clients using COM objects do not need to care about what language the object is written in, nor do they need to care about what language the object is written in.
DLL, or executed in another process. From the client side, there is no difference.
This general processing technique is very useful. For example, two applications run by users in coordination can
Their * * *, like the job part, is realized as the interaction between COM objects (of course, so is the current OLE compound document.
Can do it). The code downloaded from the Web server and executed in the browser can be regarded as COM by the browser.
Object. In other words, COM technology is also a standard way to encapsulate downloadable code (ActiveX controls do this).
A function).
Even the method for an application to interact with the native operating system can be specified by COM (Windows and Windows NT).
Most new APIs used are defined as COM objects). Although COM originated in compound document, it can be found.
Effectively applied to many software problems.
Second, ActiveX kingdom
The active platform is Microsoft's worldview. The basic idea is to build a system using ActiveX controls, including
From transaction monitors that interact with users and adapt to COM to Web servers, all organizations that realize automation.
. Active platform includes two parts: active server and active client.
The active server is actually the middle tier. Use components or dynamic server pages to provide services for enterprises.
A place where logic and main applications are handled. ActiveServer technology, whose core is NT server,
Microsoft trading server, data management service, directory service, Web service and network service.
Transaction server combines traditional TP monitoring functions (such as thread generation and database multiplication) with Microsoft's.
Component-based programming model. Other components of the active platform (such as data management services) use OLE.
DB and ODBC, access DB2 and Oracle.
