Console app

Is it possible to have an app that is both a console app and a windows app?
If there are no command line switches then it will run as a console app, if
there are command line switches then it will be a windows app. If I make it
a windows app then I can't write to the console. If I make it a console app
then it starts a console if the user runs it from the start menu so from
what I see it's not possible.

Thanks in advance,
Michael

See the code below (it is not production grade, but it is a
starting point).

Thanks for the reply. This is a good solution but isn't exactly what I need.
If someone types MyApp.exe Console at the command line then it will create a
new command window instead of using the existing one.
Hm.

I just tried.

On my system it does not create a new console window in that scenario.

Nah. That is with /t:exe, but that gives a console with start run.

Problem is by that time the console has already gone back to the prompt so
the users can type additional commands. I think something is needed to
modify the code that runs before main is called. This is probably possible
somehow but difficult.
You need a new /t: type that neither start a new process
or create a console window.

Then it will have access to the console, and it can refrain from actually
opening any windows if that's what you want.

Thanks for the reply. The problem with this approach is that when the user
starts the exe from say the start menu then a dos box appears. I'm
presuming it's not possible to do what I want because everything is done
by the time main gets called and I have no control over it before then.
The other thing it could do is the Win32 AllocConsole call to get a console.

I tried that and it does work but if you run the app from a console then it
creates a new console to send the text to, when the app closes the new
console disappears. If your app just sends a simple response then you just
get a flicker of this new console on the screen.

Thanks for all the replies. Looks like it is not possible without doing some
sort of low level hacks to modify the compile process. I'd assume this is
possible but could be messy and I generally don't like adding to the
complexity of compiling an app.

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

I am working on a little app which uses colour in the console window. I have created a class to extend the console functionality but the ClearScreen method does not work correctly. I am enclosing a complete project to show what happens. If anybody has an idea of how to fix this, please let me know. Yes I am aware that this is all in .Net 2. Thanks in advance.

Hi I have a really basic question hopefully some can help me with: Can you write a (i.e. one) C# project that works from the cmd line and gui? I seems if i write a GUI app it can't write to console using System.Console.WriteLine if thge project has its "Output Type" to "Windows Application". However I can write to stdio if i set output type to "Console Application". When I do this I unfortunately get a "console box" as well

Hello! When you have windows forms you have the same possibility as when you have a Console application to use Console.Writeln to write whatever on the screen. Now to my question: Is it possible to use Console.Writeln when you have a Webservice. I don't think it's possible but just to be sure I ask you?
