- 如何隐藏/显示任务栏?

shell db "Shell_TrayWnd",0 ; 任务栏的类名

- 如何禁止/允许/显示/隐藏开始按钮?

.data?
buffer db 127 dup(?)

.code
invoke FindWindow,addr shell,NULL ; 获得状态栏句柄
mov tray, eax
invoke GetWindow,tray, GW_CHILD ; 获得状态栏的子窗口(如果有的话)
mov child, eax
.if child != 0
invoke GetClassName,child,offset buffer, sizeof buffer ;获得子窗口类名
.if eax > 0
invoke lstrlen, offset buffer ;获得类名长度
mov slen,eax
invoke CharUpperBuff,offset buffer,slen ;转为大写
invoke lstrcmp,addr buffer, addr sbar ;将类名与'BUTTON'比较
.if eax == 0
invoke ShowWindow,child,SW_HIDE ; 隐藏开始按钮
; invoke ShowWindow,child,SW_SHOW ; 显示开始按钮
; invoke EnableWindow,child,FALSE ; 禁止开始按钮
; invoke EnableWindow,child,TRUE ; 允许开始按钮
.endif
.endif
