Read more books, read more msnd, and read more sample programs. Tired of writing :-( V. Summary Stay tuned to COM Component Design

of the earth? When designing new systems, C ++ did not consider remote implementation. (Of course, it is not necessary to design a computer language ). Therefore, the function of starting components and calling interfaces is implemented by the com system.Figure 1 component call MechanismIt can be seen that when calling a component, the communication between the proxy (running locally) and the stub (running

The most common method to call a COM component is to add a reference to this component, but this will generate an accompanying DLL such as mycom. InterOP. dll in the final executable file. Program And adding references is that we can only reference COM components of a specific version, however, we often cannot determine whether the program runs on the machine wit

In PHP, how does one call the Asscess database and COM program through ADO. Znsoft (www.phpease.comznsoftm@21cn.com) PHP4 already supports Microsoft's COM technology.

I used to know how to use native in Java and implement it through windows DLL, but I have never practiced it. I am busy today, I just tried it. The simplest example is written.The procedure is very simple. Maybe someone may use it in the fu

Then we will display the first three fields of the record set. 　　 　　 $ Dbc = new COM ("ADODB.

Service interfaces are often called across platforms and technologies. When using non-. NET technology (such as ASP and VB6) to call a WCF Service interface, you can only use the com method. There are usually three methods. 1. Use the soap object in the soap SDK 2. Use the httprequest object 3. Use the COM interface of WCF The third method is relatively s
