VS C++一つのウィンドウから別のウィンドウを作成する

一、stdafx.hファイルで、追加:
#include "Form2.h"

/ stdafx.h :              ，
//             
//           
#pragma once

// TODO:                
#include "Form2.h"

二、ボタン応答イベントに以下のコードを追加する.
Form2 ^f = gcnew Form2();f->ShowDialog();

#pragma once


namespace mYt {

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

    

    /// <summary>

    ///          “     ”  。  ，
    ///                       
    ///                   。
    /// </summary>

    public ref class Form1 : public System::Windows::Forms::Form
    {
    public:
        Form1(void)
        {
            InitializeComponent();
            //
            //TODO:            
            //
        }

    protected:
        /// <summary>
        ///            。
        /// </summary>
        ~Form1()
        {
            if (components)
            {
                delete components;
            }
        }

    protected: 

    private:

        ///         。

        System::ComponentModel::Container ^components;

#pragma region Windows Form Designer generated code

        void InitializeComponent(void)
        {
            this->button1 = (gcnew System::Windows::Forms::Button());
            this->SuspendLayout();
            // 
            // button1
            // 
            this->button1->Location = System::Drawing::Point(56, 200);
            this->button1->Name = L"button1";
            this->button1->Size = System::Drawing::Size(94, 44);
            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(8, 15);
            this->AutoScaleMode = System::Windows::Forms::AutoScaleMode::Font;
            this->ClientSize = System::Drawing::Size(500, 294);
            this->Controls->Add(this->button1);
            this->Name = L"Form1";
            this->Text = L"Form1";
            this->ResumeLayout(false);

        }
