Problem: After hiding all icons of the tray, the solution of the tray length is not updated, or other hiding methods

This method can hide all the icons of the tray, but just hide the icons, the tray area will leave a blank length, it is difficult to see, and it also has the feeling of "three hundred and two silver-free here":

HWND hTray = FindWindow (TEXT ("Shell_TrayWnd"), NULL);
if (hTray == NULL)
break;
hTray = FindWindowEx (hTray, NULL, TEXT ("TrayNotifyWnd"), NULL);
if (hTray == NULL)
break;
hTray = FindWindowEx (hTray, NULL, TEXT ("SysPager"), NULL);
if (hTray == NULL)
break;
hTray = FindWindowEx (hTray, NULL, TEXT ("ToolbarWindow32"), NULL);
if (hTray == NULL)
break;
iNum = SendMessage (hTray, TB_BUTTONCOUNT, NULL, NULL); // Get the number of icons on the taskbar
for (i = 0; i <iNum; i ++)
SendMessage (hTray, TB_HIDEBUTTON, i, TRUE);
hTray = NULL;

I tried refreshing the tray but it didn't work:
// refresh the tray
SendMessage (hTray, WM_PAINT, NULL, NULL);
RECT rect;
GetWindowRect (hTray,&rect);
InvalidateRect (hTray, NULL, FALSE);

Seek: After hiding all icons of the tray, the solution of the tray length is not updated, or other hiding methods?

TB_DELETEBUTTON does not work either. And TB_HIDEBUTTON an effect.

try SendMessage (HWND_BROADCAST, WM_SETTINGCHANGE, 0, "Environment") etc.

Under XP
SendMessage(HWND_BROADCAST,WM_SETTINGCHANGE, 0, "Environment");
No effect!
