显示器测试程序（黑、白、红、绿、蓝）–C++实现
功能实现：自定义不同的参数，屏幕输出黑、白、红、绿、蓝不同的颜色，测试显示器

	//设置窗口全屏int nFullWidth = GetSystemMetrics(SM_CXSCREEN);int nFullHeight = GetSystemMetrics(SM_CYSCREEN);CRect m_FullScreenRect;CRect WindowRect;GetWindowRect(&WindowRect);CRect ClientRect;RepositionBars(0, 0xFFFF, AFX_IDW_PANE_FIRST, CWnd::reposQuery, &ClientRect);ClientToScreen(&ClientRect);m_FullScreenRect.left = WindowRect.left - ClientRect.left;m_FullScreenRect.top = WindowRect.top - ClientRect.top;m_FullScreenRect.right = WindowRect.right - ClientRect.right + nFullWidth;m_FullScreenRect.bottom = WindowRect.bottom - ClientRect.bottom + nFullHeight;WINDOWPLACEMENT wndpl;wndpl.length = sizeof(WINDOWPLACEMENT);wndpl.flags = 0;wndpl.showCmd = SW_SHOWNORMAL;wndpl.rcNormalPosition = m_FullScreenRect;SetWindowPlacement(&wndpl);//设置背景颜色//参数1为黑色if(lstrcmp(__argv[1],"1")==0){CRect   rect; CPaintDC   dc(this); GetClientRect(rect); dc.FillSolidRect(rect,RGB(0,0,0));}//参数2为白色else if(lstrcmp(__argv[1],"2")==0){CRect   rect; CPaintDC   dc(this); GetClientRect(rect); dc.FillSolidRect(rect,RGB(255,255,255));}//参数3为红色else if(lstrcmp(__argv[1],"3")==0){CRect   rect; CPaintDC   dc(this); GetClientRect(rect); dc.FillSolidRect(rect,RGB(255,0,0));}	//参数4为绿色else if(lstrcmp(__argv[1],"4")==0){CRect   rect; CPaintDC   dc(this); GetClientRect(rect); dc.FillSolidRect(rect,RGB(0,255,0));}//参数5为蓝色else if(lstrcmp(__argv[1],"5")==0){CRect   rect; CPaintDC   dc(this); GetClientRect(rect); dc.FillSolidRect(rect,RGB(0,0,255));}// TODO: Add extra initialization hereelse{CRect   rect; CPaintDC   dc(this); GetClientRect(rect); dc.FillSolidRect(rect,RGB(0,0,0));}
