Writing to the console from a GUI application

Re: Writing to the console from a GUI application

Yes, I want to write to the console where the user typed the
application name and parameters.

It doesn't show the usage lines.

I've found some more info about this, and nobody seems to have a
solution.

One solution implies changing the aplication to a console application,
and releasing the console if it should be run in GUI mode, which will
flash a black window. Another implies creating two applications with
the same name, but one with .EXE and one with .COM extensions. Both are
very bad...

It's hard to accept that "computers can't do this", isn't it? It's
something so simple.

Maybe it's a question of getting the handlers for STDIN and STDOUT and
passing them to Console.In and Console.Out?...

Re: Writing to the console from a GUI application

Why would he need to use AllocConsole? He wants to write to the console
from which his application was invoked

Re: Writing to the console from a GUI application

The code looks fine, it doesn't write the usage statement out if you
pass the incorrect parameters?

Re: Writing to the console from a GUI application

Hello eduardorp1@gmai l.com,

You need to use API function AllocConsole
See samlpe of usin it in C# there http://groups.google.com/group/micro...2ca7a3ebfde2df

WBR,

"At times one remains faithful to a cause only because its opponents do not
cease to be insipid." (c) Friedrich Nietzsche

I have a GUI application that needs to be invoked from the command line
as well. It should work both as a GUI and as a console application.

When I invoke it from the command line, it reads all the command line
options perfectly. However, I can't use Console.WriteLi ne to write
messages to the console (the lines don't appear at the console window).

Is it possible? What should I do to "connect" the console?

My Main() is:

static void Main(string[] args)
{
if (args.Length == 0)
{
Application.Run (new WorkspaceForm() );
return;
}
if (args.Length == 2 && args[0].ToLower() == "-mycommand")
{
DoMyCommand(arg s[1]);
return;
}
Console.WriteLi ne("Usage:\n\na pplication_name -mycommand
<file>\n");
Console.WriteLi ne(" Performs mycommand on file.\n");
}


Thanks
Eduardo
