I am trying to learn Visual C++, particularly the GUI components, so I tried to make a simple program where a button is displayed to a frame and when the button is pressed, a cout statement is invoked which displays a message to the console saying that the button has been pressed. I created a new project of type "Windows Forms Application", then dragged a button onto the GUI, brought up the properties and added a "button_1_Click" function. Within that function I added a simple cout statement. The problem is that I see nothing displayed when I click that button. Here is my code (auto-generated except for a couple of lines - cout line is line 89):

#pragma once

#include <iostream>


namespace trialprogram1 
{
    using namespace System;
    using namespace System::ComponentModel;
    using namespace System::Collections;
    using namespace System::Windows::Forms;
    using namespace System::Data;
    using namespace System::Drawing;

    public ref class Form1 : public System::Windows::Forms::Form
    {
    public:
        Form1(void)
        {
            InitializeComponent();
            //
            //TODO: Add the constructor code here
            //

            if (components)
            {
                delete components;
            }
        }
    private: System::Windows::Forms::Button^  button1;
    protected: 

    private:
        /// <summary>

        {
            this->button1 = (gcnew System::Windows::Forms::Button());
            this->SuspendLayout();
            // 
            // button1
            // 
            this->button1->Location = System::Drawing::Point(39, 23);
            this->button1->Name = L"button1";
            this->button1->Size = System::Drawing::Size(75, 23);
            this->button1->TabIndex = 0;
            this->button1->Text = L"button1";
            this->button1->UseVisualStyleBackColor = true;
            this->button1->Click += gcnew System::EventHandler(this, &Form1::button1_Click);
            // 
            // Form1
            // 
            this->AutoScaleDimensions = System::Drawing::SizeF(6, 13);
            this->AutoScaleMode = System::Windows::Forms::AutoScaleMode::Font;
            this->ClientSize = System::Drawing::Size(292, 266);
            this->Controls->Add(this->button1);
            this->Name = L"Form1";
            this->Text = L"Form1";
            this->ResumeLayout(false);

        }
#pragma endregion
    private: System::Void button1_Click(System::Object^  sender, System::EventArgs^  e) 
        {
            std::cout << "button1 has been pushed\n";
        }
    };
}
// trialprogram1.cpp : main project file.

#include "stdafx.h"
#include "Form1.h"

using namespace trialprogram1;

[STAThreadAttribute]
int main(array<System::String ^> ^args)
{
	// Enabling Windows XP visual effects before any controls are created
	Application::EnableVisualStyles();
	Application::SetCompatibleTextRenderingDefault(false); 

	// Create the main window and run it
	Application::Run(gcnew Form1());
	return 0;
}

I put a breakpoint on line 89 to make sure that function is being called when the button is pressed, and it is. However, I see no output when I click this button.

You should have gotten a runtime exception for trying it...

Anyway, Windows apps don't have consoles by default. At the beginning of your program you'll have to AllocConsole(); then... you'll have to hook the standard streams up to the console:

(yoinks!)
Its easier than it looks.

Have fun.

Good link.

All right, that worked! And on the first try for once. It was interesting that this was mostly C code in that link. Basically I cut and pasted guicon.h and guicon.cpp verbatim, then added a call to RedirectToConsole () before any cout statements. I may fiddle with it, but then again, if it ain't broke, don't fix it. Thanks for the link.
