/// 获取托盘某个图标的坐标区域，如果要隐藏某个图标例如音量的图标，也很方便，改改就可以了
function GetSysTrayIconRect(Text: string): TRect;
{
返回托盘中指定文字的图标的矩形区域。
例如返回音量控制图标的矩形区域：
GetSysTrayIconRect('音量');
}
begin

end;
function GetSysTrayWnd: HWND;
{
返回托盘的句柄，适合于WinXP以上版本

end;
function GetToolBarButtonRect(hWnd: HWND; Title: string): TRect;
{
返回指定工具栏对应的按钮指定文本的矩形区域
hWnd:工具栏句柄，Title：需要返回矩形区域的按钮文字
返回值：指定按钮的边界矩形，屏幕坐标
