C# :: Communicate Between Two Applications?
Jan 1, 2015
I'm working a personal project where I have two applications namely Server, Client. when Server is started, it continuously transmits data. When Client is opened, it is ready to consume the data and display it.
I will put both .exe files in a shared location (LAN). Therefore Sever and Client will be launched from different machines. When I searched for articles that teach how to establish communication between the two, I was offered with choices like NamedPipes, WCF, Polling etc.. I'm not sure whether they will work in a LAN based environment.Also are there any other means of establishing communication?

I have a device that have some communication protocols and it will respond and send some specific data when somebody communicates with the device. I tried to build a C code that will send those protocols to the device and then store those sending data. Now I don't understand that how to send those commands. Other things than that I can manage with the file handling programming.Is there any predefined function using which it will send some specific data or something like that??

I've coded this client/server application and it works fine becuase a client can send a message to the server, so is the server to the client and mutiple clients can be connected to the server at the same time. But my problem is that I want two client to be able to communication with each other through the server. What I don't know how to do is to relay a message in the server from one client to the other. Is there a way to do this? By the way this is a chat application i'm creating.

Any time I run my program after I make a selection from the menu the output is printed on the console screen then immediately a windows screen comes up saying project.exe has stopped working.
Below is my code, and I suspect the error has something to either
A) due with how I'm calling the method or
B) how I have the method coded.
Main
#include <iostream>
#include <fstream>
#include <string>
#include "telephone.h"
#include "tbook.h"
[Code] .....

I need to write a windows form application that allows the user to enter a credit card number and credit card type and then determines whether it is a valid number using the following rules:
1.) the first number is:
a. 4 for visa
b. 5 for master card
c. 37 for american express
d. 6 for discover
2.) passes the mod 10/ luhn check, which is calculated as:
a. from right to left, multiply every other digit by 2. when doubling a digit results in a two digit number, add the numbers to get
a single digit. ( like 6 * 2 = 12 therefore 1 + 2 = 3).
b. add all the single digits from 2a
c. add all the odd places from right to left in the card number
d. sum the results fro steps 2b and 2c
e. if the resulting number in 2c is divisible by 10, the card number is valid otherwise it is invalid.
The chapter is introducing methods so that is the main thing i will be using for each step.

I want to create an application that automatize different applications in the sense that my application will be able to press automatically different buttons on another application.
For example: my application will start, let's say, Microsoft Office, will press some buttons in MSOffice, and will close MSOffice.

I'm looking for a library which enables me to take screenshots of a all open applications, and store them as .bmp or .jpg .
I've tried to find something but so far no luck
I don't necessarily need code just a library with good understandable documentation (if such a thing exists). Also, is something like this possible for a beginner-intermediate c++ user? If not where should I start?

I have a service that has some settings. As the service is running as a system user, the settings file is located in
C:Windowssystem32configsystemprofileAppDataLocal<PRODUCTNAME><ExecutableName+GUID><VERSION>user.config
Now i want to be able to change some settings at runtime using a normal Winforms App. Is there a good and easy way to change the user.config of a different application directly? I tried with ConfigurationManager but that does not seem to work.

I'm trying figure out how Windows Firewall functions by experimenting with Bittorrent's add exception to windows firewall option, I deleted the entry from the Firewall options and also located that the regkeys are in HKLM/System/CurrentControlSet/Services/SharedAccess/Parameters/FirewwallPolicy but I can't figure out what registries are made when an application is added as an exception in the Windows Registry.

I will sketch the scenario I would like to get working below. I have one main application.
That application, based on user interactions, can load other applications in a secure shell. This means these child applications cannot interact with the OS anymore, nor with each other.
The parent program can at any time call functions of these child programs.
The child program can at any time call functions of these parent programs.
How to implement this in C++? Preferably both parent and child should be written in C++.
The performance of loading the child applications doesn't matter. The only thing that matters is the performance of the communication between child and parent.
