获得窗体指针的办法FromHandle,WindowFromPoint

HWND hWnd = GetSafeHwnd();

CWnd* pWnd = FromHandle(hWnd);

CPoint point;

GetCursorPos(&point);

CWnd* pWnd = WindowFromPoint(point);

//设置窗口的层次使其置顶局中显示

SetWindowPos(&wndTopMost, 0, 0, 0, 0, SWP_NOSIZE | SWP_NOMOVE);//static AFX_DATA const CWnd wndTopMost; // SetWindowPos pWndInsertAfter定义在afxwin.h

CenterWindow();

CRect rect;

GetWindowRect(rect);

rect.OffsetRect(0,0);

MoveWindow(rect);

FlashWindow(TRUE/FALSE)可以产生类似QQ的闪烁效果

SetWindowRgn()可以设置窗体区域，从而产生透明窗体的效果

//显示动画窗口

AnimateWindow(1000, AW_BLEND);//可以让窗体渐渐显示出来

//获得桌面窗口

CWnd* pWnd = CWnd::GetDesktopWindow();

//最小化所有桌面窗体

//获得任务栏窗口

CWnd* pWnd = CWnd::FindWindow(_T("Shell_TrayWnd"), NULL);

//发送ID为0x1F5（Win + M）的WM_HOTKEY消息

pWnd->SendMessage(WM_HOTKEY, 0x1F5);
