wince 隐藏、显示任务栏

　　有时候需要将任务栏隐藏，封装了一个类。在窗口load的时候，先调用hide(),窗口大小设置成屏幕大小就可以了。将windowstate设置成max不起作用，必须将窗口大小设置成屏幕大小

const uint SHFS_HIDESIPBUTTON = 0x0008;
const uint SHFS_SHOWSTARTICON = 0x0010;
const uint SHFS_HIDESTARTICON = 0x0020;
const int SW_HIDE = 0;
const int SW_SHOWNORMAL = 1;

const int SW_SHOWMAXIMIZED = 3;
const int SW_SHOWNOACTIVATE = 4;
const int SW_RESTORE = 9;
const int SW_SHOWDEFAULT = 10;
