How to Transfer files from one EXE to Other EXE

I am having two EXE's say EXE1 and EXE2..

I am writing a textfile using EXE1.
As soon as EXE1 writes a file it should send an acknowledgement to EXE2.
So that EXE2 can read that file.

How to do this using TCP or any other IPC.

The main Thing is that EXE2 should not use most of the CPU.
Because I tried the below in EXE2

C#

while(true)
{

    if(File.Exists(Path)
        {
        }
}

It almost use 99 Percentage of CPU Usage.
How to get rid of this.
Can anyone help me with code.

The problem does not have anything to do with TCP. It has to do with sharing data.

In exe1, create a named AutoResetEvent setting the initial state to not signalled.
In exe2, create the same named AutoResetEvent setting the initial state to not signalled and WaitOne ( Timeout.Infinite ).
When exe1 completes writing the file, Set ( ) the event. That will allow exe2 to execute.

Can you answer with a code Sir.

Solution 1

You should use WCF (Windows Communication Foundation) based on NetTcpBinding (net.tcp or other binding) and for doing this you should:

1.You EXE2 should be the WCF server (that expose a WCF service to be used by others applications);

2.You EXE! should be the WCF client.

3.Here are some articles that could be used by you as WCF starting points:

I am using .Net Framework 2.0 So I cant use WCF.
Any alternate idea sir?

In this case you have the next options:
1)Use .NET Remoting:

2)Use .NET Named pipes:

Solution 2

To reduce CPU usage you need to put your thread to sleep.
Or else it will block by constantly loop in your while loop.

like this.

C#

//Add "using System.Threading;"
while(true)
{
    if(File.Exists(Path))
        {
        }
Thread.Sleep(1);
}

For TCP communication you need a server and a client (or multiple clients).
Take a look atTcpListener[^] for server and TcpClient[^] for clients. Good luck.

I don't even want TCP I want to read data only when file is existing.
When we do While(true)
it often loops so taking much process.
I make other EXE slow that's why I want the EXE2 to work only when file is existing that reduces the process

Splitting logic into 2 EXE will make your head spin.
It´s hard work (debugging) and useless if you do it to reduce CPU.
Make sure your thread is not blocking by using Thread.Sleep as i showed, that will be enough to decrease CPU usage.
Also take a look at multithreading if you need to do parallell processing.
Multiple threads are way better then multiple applications (up to a certain point).

Thanks Sir

Your welcome.
By the way, you should not write a question how to use TCP perfectly, if you dont want TCP :).

Can you suggest a question for this existing or can you Edit the question depending upon your Answer

Per Söderlund 20-Aug-14 3:08am

I´m not sure i understand what you mean.
You can edit your question if you want.
Should say "improve question" or "edit" or something by your signature in the question.
