功能：滑動條變化，顯示對應(yīng)的值，同時，使得產(chǎn)生一個顏色，來設(shè)置字體的顏色。
很簡單的。。
貼代碼：
m_slider1.SetRangeMin(0); //初始化設(shè)定滑動條的最小值
m_slider1.SetRangeMax(255); //初始化設(shè)定滑動條的最大值
m_slider1.SetPos(0); //初始化設(shè)定初始位置
m_slider3.SetRangeMin(0);
m_slider2.SetRangeMax(255);
m_slider2.SetPos(0);
m_slider3.SetRangeMin(0);
m_slider3.SetRangeMax(255);
m_slider3.SetPos(0);
m_edit.SetWindowText("Hello,world!");
m_edit2 = 0;
m_edit3 = 0;
m_edit4 = 0;
UpdateData(FALSE);
