本文 Visual Studio 2005 Express Edition C++を利用して、あるボタンが押下されたときに新ウィンドウを立ち上げ、新ウィンドウ内のボタンを押したときに新ウィンドウを消去させたいのですが、どういう記述をすればよいのでしょうか？ アドバイスのほど、よろしくお願い致します。m(__)m 以下がソースです。 #pragma once namespace My777 { 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 { private: System::Windows::Forms::Button^ ButtonXXX; public: Form1(void) { InitializeComponent(); } protected: ~Form1() { if (components) { delete components; } } private: System::Windows::Forms::Button^ button1; 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(93, 93); this->button1->Name = L"button1"; this->button1->Size = System::Drawing::Size(102, 45); 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, 12); 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 //button1が押下された private: System::Void button1_Click(System::Object^ sender, System::EventArgs^ e) { System::Windows::Forms::Form^ Form2 = gcnew Form; Form2->Text = L"test"; Form2->Width = 315; Form2->Height = 145; Form2->MinimumSize = System::Drawing::Size(315,145); Form2->MaximumSize = System::Drawing::Size(315,145); Form2->StartPosition = System::Windows::Forms::FormStartPosition::CenterScreen; Form2->Activate(); Form2->Show(); Form2->Refresh(); ButtonXXX = gcnew System::Windows::Forms::Button(); ButtonXXX->Parent = Form2; ButtonXXX->AutoSize = true; ButtonXXX->Width = 250; ButtonXXX->Location = System::Drawing::Point(10,30); ButtonXXX->ForeColor = System::Drawing::Color::Black; ButtonXXX->Name = L"ButtonXXX"; ButtonXXX->Size = System::Drawing::Size(5, 12); ButtonXXX->Text = L"ボタン"; } //ボタンが押下された private: System::Void ButtonXXX_Click(System::Object^ sender, System::EventArgs^ e) { //新ウィンドウを消去する。 } }; }
