Hi friends,

I am in need to perform InterProcessCommunication. I have gone thru the PIPES and SOCKETS to do the same but unable to decide which one is the best and efficient.

Could anybody help me out in understanding which one is more efficient and why?

Thanks in advance

There's too many "depends" here for me to work with.

Are the processes on the same PC? In the same building? Is one end an alien spaceship, and you're trying to plant a virus?

Are both the same OS? If yes, might that answer change?

No, that's too much hard work for me, and I'm not getting paid for this.

If you have a scenario in mind, I may be able to help. It also depends on your skills and previous knowledge.

How to convert COM dll to Normal dll

Pipes provide an easier programming interface than sockets.

Depending on the situation, a pipe may use sockets as its underlying transport mechanism,
so in that case, a pipe may be a little less efficient.

Maybe use the one that has the features you need for your application.

Or try both and see which is more efficient for you. I would guess the performance
difference is minimal.

what's the problem you face in registering the DLL, or why you want it to be used without registering.

normally COM dll exports some set of functions that are used by COM library to create the COM instances, then with normal dll what you are expecting to do?

How to install "ttf" file through Program VC++

21-Apr-08 22:27

Go on then.

Oh, you want me to pretend you had a question?

COM dll's *are* normal DLLs. They have two functions exported by definition: One to register interfaces, and one to get an object, given a GUID.

There's nothing stopping you writing another exported function in the same way, and call it:

HRESULT GiveMeAnObjectUsingThisPrivateMethod (IMyObject **ppObject);

And then treat the ppObject in the same way, Release, AddRef, etc, and the COM infrastructure needs to know nothing about you. You can also keep the code for the object you've already written this way.

But only someone who knows about GiveMeAnObjectUsingThisPrivateMethod will be able to use it...

Hello,
Thanks for the Link. I have question regarding the article. I followed the steps dictated in the link. In step 3 (Adding a property to the Control)the article says the prototypes of get & set functions are created int polyCtl.h and empty functions are created in polyCtl.cpp.

But when I tried the same, say added a propery named Sides, the get and set functions did not get created in the .h and .cpp file. But as they said the propget,propput god added in the polygon.idl.

Can you say that this behaviour is common?

LG

Did you recompile the IDL?
This should generate the functions for you

Normally it should,
nevertheless could you try to compile the .IDL yourself?

Hi,
I compiled the .IDL but it did't happen so I added the function declaration on the .h file and the definitions in the .cpp file. And proceeded further, and I got the desired output.
Thanks for the link. Smile | :)
