I've made a console application and a windowsforms application. They both work together and i wonder if there's a way to log the console application output to a richtextbox in the other project?
Yes, there is a way. You run the console app from within the forms app and put the output into the text box.
The Process class has methods to start the console app and grab its output, then you stuff that output into the text box. There are plenty of details for you to look over but it's pretty straightforward.

I have created a windows form app that does a few things before having a new application take over from there.
The new application needs to be a separate project within the same solution, using references for the functions to be called from the original app.
The original app will call different functions within the console app and the console app will do some processing and show output based on what has been called. Almost like a log.
The problem I am facing by adding a console app is that the console app closes immediately when the last line in main is run.
So the question is can a separate project be created that prints messages to console with persistence(Continuous running)?
It does not necessarily have to be a console output, but it would be preferred.
Appreciate the help.
I am trying to develope a windows application to display console window as output.
If i changed output type in properties to "console Application" both the console window and form showing. But i need to show only form window first, when i click a button then only the console window need to display the output value.
Please guide me...
Thanks in advance.
Each process can have only at most one console associated with it. There are several paths you can take: either you hide the console window immediately on startup and show it later (via ShowWindow), or you leave the project as a window application, and create the console manually using AllocConsole later.
In the case you wanted multiple consoles, you can e.g. create a dummy process (cmd) and attach your process to its console, using AttachConsole. The managed way would be to use remoting or other techniques to communicate with the dummy process (with your own implementation), and print texts through that.
Use NativeMethods.AllocConsole(); to allocate a console and I/O with it.
Use NativeMethods.FreeConsole(); to close and free this console.
You wanna output the Console.WriteLines of a Windows Forms app inside the form?
In that case just use Console.SetOut(Stream) and pass in something you're wrapping so you can also output it somewhere else.
Another option is to switch all your Console.WriteLines to Trace.WriteLine and add a TraceListener somewhere that does what you want.
I want to be able to display a console window at will in my C# unit tests that I can later address in my code to print statements to. is there a system command to support for this? My intention is debug purposes but I don't want to use log4net or some other text/xml file for accomplishing that.
Just use Console.WriteLine. Every unit test runner that I've used has captured console output automatically - you don't need an actual console window for that.
If i understand your question correctly, follow the steps mentioned below
1- Right click the console project
2- Go to the Application section
3- In the dropdown named "Output Type" select "Console Application".
4- Save and run the application
what this will do is, it will open the console along with the winform. Whereever you will write Console.Writeline, it will show in the console. (Your form will keep on running as it is.)
If you really need a console window, consider access AllocConsole via p/Invoke:

I'm developing an application which acts as a GUI for Minecraft Server (runs as a console Java application).
I have finished it and I also want to add a console inside the Winforms application because I want to give users more control over the program. But using streams (Process.StandardOutput) I can't simulate a console as it sometimes changes the cursor position, clears the console, etc...
So, I want to embed the process into the application somehow. The first solution I tried was removing the borders and positioning it accordingly to the form's position but unfortunately I couldn't do it.
Any working code snippets would be greatly appreciated!
You cannot target both subsystem gui and console in the same module (msdn).
Instead, you could add a separate console application that uses SOAP to communicate with your application. Take a look at WCF to achieve this task.
I am trying to writing a console application. It has its original console, let's name it console A. And I want this application to do the following things via C#:
Open another console B in another thread, then get input from A and output it to B;
type a command in A, such as dir, and show the output in B;
while doing the above things (still not done yet. X_X ), I find myself lack a through understanding of what a console window is, and how it is assigned to a console application, especially the very first console when my console application starts to run. Could some one shed some light on me?
Is console window physically a memory area in the video memory? Or something else?
Could different threads within the same process have different console of its own for its own I/O?
Many thanks.
Now I am using one console application to start another console application in a new process. Thus I can have 2 consoles output at the same time.
My understanding now is that, for Windows OS, a console is a special window, and it's a system resource that OS assigned to the application without-a-UI as a necessary user interface. Windows OS handles the wiring between the system-prepared console window with our UI-less application.
In Windows terms, a Console is a textual GUI window that you see when you run "cmd.exe". It allows you to write text to, and read text from, a window without the window having any other UI chrome such as toolbars, menus, tabs, etc,..
To get started you'll want to load Visual Studio, create a new project and choose "Console Application". Change the boilerplate code that Visual Studio produces to:
using System;
using System.Text;
namespace MyConsoleApp
{
class Program
{
static void Main(string[] args)
{
Console.Write("Hello, world!");
Console.ReadKey();
}
}
}
When you run your application, a console window will open with the text "Hello, world!" and it'll stay open until you press a key. That is a console application.
Is console window physically a memory area in the video memory? Or something else?
It's not physically a memory area in video memory, it's "something else". The Wikipedia Win32 console page gives a fairly robust descrption of the ins and outs.
A console application has only one window. It does not have window management functions in order to spawn child "consoles".
You can start additional console applications, but these are separate entities.
No. It's a windows GUI subsystem. In WinAPI there are functions to work with console: http://msdn.microsoft.com/en-us/library/ms682073%28VS.85%29.aspx
A (OS) console is a process (containg one or more threads of executions, all of them sharing the same memory space), and this process has:
standard input (a stream of input bytes), what you key in
standard output (a stream of output bytes), what the program prints
standard error (a stream of output bytes), what the program prints when it's complaining about something
So if you want to create another console (from .Net) and link the input/outputs I understand you have to create a process (executing "cmd.exe" by example).
I don't know the API of .Net for process manipulation but if it's like Java you can hook up stdin, out and err so you can play with your created process from the original one.
A windows application can have one console, or no console, it can't have more than one. See the documentation for AllocConsole.
The console is basically an emulation of the 'pre-Windows' days when there would literally be a 'control console' i.e. a keyboard and screen attached to a mainframe computer.
To do what you want you could spawn another process with its own console and communicate between the two, or make a GUI application which looks like a console window.
