Console output in a window / text box

Hello,

i've been dealing with this problem whole morning, but havent quite
figured out the solution. The thing is: i have a C# program that calls
a function from a C++ dll. While running, the function uses "cout" a
lot, to print out useful data. Now here is the problem: this data is
being written in an output window and i want to redirect this data to
an application window or a text box. If thats not possible, then the
data should be at least written to a console window, that would come
up, when this function is called.

Any help would be greatly appreciated, thanks

Roosty,

You can create a class that derives from TextWriter, overriding the
Write method (that takes a single character) and then having that fire an
event every time a character is written. Then, you can just call SetOut on
the Console class, passing an instance of your TextWriter.

You would then hook to an event on your text writer, which is fired
every time the character is written.

Overriding the Write method that takes a character is the minimum you
would have to do. However, this would result in a good number of events
being fired.

You could override some of the more specific methods, if you wish, for
the sake of performance.

This should capture the results of writing to cout from your unmanaged
DLL, and then you can display them anyway you wish.

Hope this helps.

Hello Nicholas, thanks for replying so quickly. Well, im quite new to
C# , so would it be too much trouble for you to write the code of
exactly what you mean. I have seen quite a few similar questions, but
none of the answers offered the exact solution code.

Hello, Does anyone know how I can read the ASCII text from a console window (from another application) in WinXP? It doesn't sound like a major operation, but although I can find the window via pywin32, I haven't been able to do anything with it. I'd really just like to get the window text into a string. By "console window", I mean the sort of thing that comes up when you run "command" (although this particular one is for the game...

This is long. Bear with me, as I will really go through all the convoluted stuff that shows there is a problem with streams (at least when used to redirect stdout).

I've written a component for this, and a test application for the component. It allows me to specify a command to execute,...

Hi, I'm programming a WinForm application. I would like to enter commands that will send output that will help me to locate bugs in the future. I know that there is a way to send output by using the Console.Write command. The question is how can I see the outputs in the client machine ? Is there a specific programm to do it or Can I use the prompt window ?

Hi, can I detect whether my class is running within the context of a Console application, vs say a WinForm's application ? also does anyone know whether the compiler or runtime is smart enough to avoid the overhead of writing to the console if it is not visible, eg I am running inside a WinForm application. thanks

Hi. I've got a C++ program written in Visual C++ 2003. The program is trivial, created with the Program-creation wizard: used the .NET "Form" template. The program has a trivial single-pane form GUI. I've got some stdout print statements in the code ... but I cannot find where in the world the output text is appearing. For printing I tried both: printf ("Hello world\n"); and Console::Write ("Hello World\n");

Hi, I'm using Vstudio 2005 and I did a Windows Application project where I also want to read arguments from command line and output some text when appropriate (for example, typing the correct command line sintaxe) Reading command line arguments is very easy : just change the 'static void Main()' in Program.cs to 'static void Main(string args)' and later access them from the string array args.
