　　代码四

void CQQHideWndDlg::FixMoving(UINT fwSide   LPRECT pRect)POINT curPos;GetCursorPos(&curPos);INT screenHeight = GetSystemMetrics(SM_CYSCREEN);INT screenWidth = GetSystemMetrics(SM_CXSCREEN);INT height = pRect  >bottom    pRect  >top;INT width = pRect  >right    pRect  >left;
if (curPos  y <= INTERVAL) //粘附在上边pRect  >bottom = height    m_edgeHeight;pRect  >top =   m_edgeHeight;m_hideMode = HM_TOP;else if(curPos  y >= (screenHeight    INTERVAL    m_taskBarHeight)) //粘附在下边pRect  >top = screenHeight    m_taskBarHeight    height;pRect  >bottom = screenHeight    m_taskBarHeight;m_hideMode = HM_BOTTOM;else if (curPos  x < INTERVAL) //粘附在左边 if(!m_isSizeChanged)CRect tRect;GetWindowRect(tRect);m_oldWndHeight = tRect  Height(); pRect  >right = width;pRect  >left =   ;pRect  >top =   m_edgeHeight;pRect  >bottom = screenHeight    m_taskBarHeight;m_isSizeChanged = TRUE;m_hideMode = HM_LEFT;else if(curPos  x >= (screenWidth    INTERVAL)) //粘附在右边if(!m_isSizeChanged)CRect tRect;GetWindowRect(tRect);m_oldWndHeight = tRect  Height(); pRect  >left = screenWidth    width;pRect  >right = screenWidth;pRect  >top =   m_edgeHeight;pRect  >bottom = screenHeight    m_taskBarHeight;m_isSizeChanged = TRUE;m_hideMode = HM_RIGHT;else //不粘附if(m_isSizeChanged) //如果收缩到两边  则拖出来后会变回原来大小//在  拖动不显示窗口内容下  只有光栅变回原来大小pRect  >bottom = pRect  >top + m_oldWndHeight;m_isSizeChanged = FALSE;if(m_isSetTimer) //如果Timer开启了  则关闭之if(KillTimer(  ) ==   )m_isSetTimer = FALSE;m_hideMode = HM_NONE;GetDlgItem(IDC_TIMER)  >SetWindowText(  Timer off  );

　　收缩模式和位置决定后剩下的工作就由最后两个核心函数完成了实现收缩的DoHide() 实现伸展的DoShow() 在这两个过程中m_hsFinished m_hiding 这两个变量起到很重要的控制作用由于伸缩过程没完成时 hsFinished始终为FALSE 所以Timer 不会关闭于是在OnTimer中会重复调用这两个函数之一在这两个函数体内窗口位置有规律地递减或递增就可以达到QQ的抽屉效果了有趣的是即使伸缩过程还没完成你也可以在这个过程中改变m_hiding这个值来决定他是伸还是缩正如QQ一样你可以把Timer 的事件间隔调大一点然后在窗口伸缩时鼠标来回地进出窗口就会很容易看到这样有趣的效果（还没缩进去又被拉了出来或者还没拉出来又缩进去了）

　　代码五

void CQQHideWndDlg::DoHide()if(m_hideMode == HM_NONE)return;
CRect tRect;GetWindowRect(tRect);
INT height = tRect  Height();INT width = tRect  Width();
INT steps =   ;
switch(m_hideMode)case HM_TOP:steps = height/HS_STEPS;tRect  bottom   = steps;if(tRect  bottom <= m_edgeWidth) //你可以把下面一句替换上面的       +=|  =steps 达到取消抽屉效果//更好的办法是添加个BOOL值来控制  其他case同样  tRect  bottom = m_edgeWidth;m_hsFinished = TRUE; //完成隐藏过程tRect  top = tRect  bottom    height; break;case HM_BOTTOM:steps = height/HS_STEPS;tRect  top += steps;if(tRect  top >= (GetSystemMetrics(SM_CYSCREEN)    m_edgeWidth))tRect  top = GetSystemMetrics(SM_CYSCREEN)    m_edgeWidth;m_hsFinished = TRUE;tRect  bottom = tRect  top + height;break;case HM_LEFT:steps = width/HS_STEPS;tRect  right   = steps;if(tRect  right <= m_edgeWidth)tRect  right = m_edgeWidth;m_hsFinished = TRUE;tRect  left = tRect  right    width;tRect  top =   m_edgeHeight;tRect  bottom = GetSystemMetrics(SM_CYSCREEN)    m_taskBarHeight;break;case HM_RIGHT:steps = width/HS_STEPS;tRect  left += steps;if(tRect  left >= (GetSystemMetrics(SM_CXSCREEN)    m_edgeWidth))tRect  left = GetSystemMetrics(SM_CXSCREEN)    m_edgeWidth;m_hsFinished = TRUE; tRect  right = tRect  left + width;tRect  top =   m_edgeHeight;tRect  bottom = GetSystemMetrics(SM_CYSCREEN)    m_taskBarHeight;break;default:break;
SetWindowPos(&wndTopMost  tRect);
