Console with a WinForm

Often, you need a console window together with a WinForm application. It can be very handy for debugging purposes while developping, but also for a (temporary) logging of some data. It is very simple to do. The following program demonstrates it, using P/Invoke.

Start a new Windows application, drop a CheckBox on the form, name it ViewConsole, and copy the following code into it.

using System;
using System.Windows.Forms;
using System.Runtime.InteropServices;    // needed to call external
                                         // application (winAPI dll)

namespace WindowsApplication1
{
   partial class Form1: Form
   {
      public Form1()
      {
         InitializeComponent();
      }

      private void ViewConsole_CheckedChanged(object sender,
                                              EventArgs e)
      {
         if (ViewConsole.Checked)
            Win32.AllocConsole();
         else
            Win32.FreeConsole();
      }
   }

   public class Win32
   {
      [DllImport("kernel32.dll")]
      public static extern Boolean AllocConsole();
      [DllImport("kernel32.dll")]
      public static extern Boolean FreeConsole();
   }
}

  • On-demand Event Event Date: September 10, 2014 Modern mobile applications connect systems-of-engagement (mobile apps) with systems-of-record (traditional IT) to deliver new and innovative business value. But the lifecycle for development of mobile apps is also new and different. Emerging trends in mobile development call for faster delivery of incremental features, coupled with feedback from the users of the app "in the wild." This loop of continuous delivery and continuous feedback is how the best mobile …
