推荐答案

我是这样做的：

I did it like this:

MainForm(void)
		{
			InitializeComponent();
			this->pictureBox1->Click += gcnew System::EventHandler(this, &AI_Events::MainForm::OnClick);
			this->rnd = gcnew Random(1234);
			this->imgFile = gcnew String("D:\\Code\\star.png");
			this->Init();
		}


void MainForm::Init()
	{
		this->pictureBox1->SizeMode = PictureBoxSizeMode::Zoom;
		this->pictureBox1->Image = Image::FromFile(this->imgFile);
	}

void MainForm::OnClick(System::Object ^sender, System::EventArgs ^e)
	{
		Rectangle rt = this->panel1->Bounds;
		Rectangle rp = this->pictureBox1->Bounds;
		int xrnd = this->rnd->Next(rt.Left, rt.Right - rp.Width);
		int yrnd = this->rnd->Next(rt.Top, rt.Bottom - rp.Height);
		Point p(xrnd, yrnd);
		this->pictureBox1->Location = p;
		String^ t = xrnd.ToString();
		t += "," + yrnd.ToString();
		this->Msg(t);
	}
