Problem using a ConsoleAppender in a Windows Form application

[Michael SALOMON]

Hi !

I'm using log4net 1.2.10.0 and .NET 2.0

I wrote a Windows Form application and I want to be able to log debug
messages in a ColoredConsoleAppender (or whatever type of Console appender).

If I compile my application as a Console Application, this works fine... If
I compile it as a Windows Forms application, then I understand that no
console is attached to my application, fair enough..

In this case I programmaticaly attach a brand new console by using this
piece of code :

        [DllImport("kernel32.dll", SetLastError = true)]
        [return: MarshalAs(UnmanagedType.Bool)]
        static extern bool AllocConsole();

        [DllImport("kernel32.dll", SetLastError = true)]
        [return: MarshalAs(UnmanagedType.Bool)]
        static extern bool FreeConsole();

        [DllImport("kernel32.dll", SetLastError = true)]
        private static extern bool AttachConsole(int dwProcessId);

        public static void SetConsole()
        {
            foreach (log4net.Appender.IAppender appender in
log4net.LogManager.GetRepository().GetAppenders())
            {
                System.Type type = appender.GetType();

                if ((type ==
typeof(log4net.Appender.ColoredConsoleAppender))
                    || (type == typeof(log4net.Appender.ConsoleAppender)))
                {
                    if (AllocConsole())
                        AttachConsole(-1);

                    return;
                }
            }

So at startup, if any console appender is found, I attach a console...

At this stage, I can do things like : Console.WriteLine() , and it works
very fine, I can see the messages in my new console...

But for some reason, the Console Appenders do not forward their messages to
this console...

Do I miss something or do something wrong ?

I tried to create a custom appender that inherits ConsoleAppender and do
something like:

protected override void Append (LoggingEvent loggingEvent)
{
    Console.WriteLine (RenderLoggingEvent(loggingEvent);
}

This works fine with my attached console, but I loose all the nice colored
features... And fact is I do want them :)

Thanks a lot for your help
