Would it be correct to say that frontend softwares as well as viruses are connected to backend softwares as well as the O.S. itself through automation and COM...?

What I have tried:

No, it would not be correct. You need to look at each individual application to see how they connect. COM and automation are used in many, but not all applications.

Okay thanks for increasing my knowledge a bit. That means not all but some suppose database sw uses this technique. Sir one thing....Developing Activex objects is a special technique. How C# could help me in this regard...?

This is the Quick Answers forum. If you want to learn about some technique or framework then you should use Google to find white papers and tutorials. BTW, ActiveX is dead.

If ActiveX is dead then how come the softwares connect each other...

Forget ActiveX, it is no longer supported.
If ActiveX is dead then how come the softwares connect each other...
ActiveX is dead and has been for a very long time, because it's a very insecure way to do things.

Modern software uses Sockets to process communications between separate apps.

And not all software is divided into "front end" and "back end": some is, some isn't.

Forget OLE automation: think about your problem from a modern software perspective instead.

Sir I'm now developing a report builder software through which you could view reports generated from several databases. for that i have to connect to databases and the report builder. As we have GUI so a specific table/tables on which report has to be generated. For that reason i was thinking of ole automation

Sir I agree absolutely that activex is dead but there is COM Interop through which I could call external database into my app. If this process is posible then please guide me

Oh...! Another thing i forget to tell; that is my reportbuilder sw could connect to other sw suppose a graph-designer sw and provide oppurtunity to design that graph sw within my sw.
