我正在编写批处理文件以自动执行一些故障排除步骤。首先,我想确定用户是否在其Internet Explorer浏览器上启用了“保护模式”。如果他们这样做,我想提示他们关掉它。我通过系统注册表执行此操作。
我确信注册表项是正确的,因为我已将值从0更改为3,并且它的行为符合我的预期,在Internet Explorer中切换Internet区域的“保护模式”设置。
以下是当前代码:
@echo off
Setlocal EnableDelayedExpansion
REM Check protected mode
echo Checking Internet Explorer settings
set "regCmd=reg query "HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Internet Settings\Zones\3" /v 2500"
for /f "usebackq tokens=3* delims= " %%a in (`!regCmd!`) do (
set /a ProtectedMode=%%a
)
if !ProtectedMode! == 0 (
echo Protected mode in Internet Explorer is enabled. It is recommended that protected mode be disabled in Internet Explorer.
echo.
set /P b_disable="Would you like to disable protected mode in Internet Explorer? (y/n)"
)
REM Checking to see that b_disable is set appropriately, it is
echo !b_disable!
REM Update protected mode to turn it off
if !b_disable!=="y" (
echo Protected mode for Internet Explorer disabled.
)
if !b_disable!=="n" (
echo Protected mode for Internet Explorer was NOT disabled.
)
pause
当我启用保护模式时,输出当前是:
检查Internet Explorer设置
启用Internet Explorer中的保护模式。建议 在Internet Explorer中禁用该保护模式。
是否要在Internet Explorer(y / n)y
中禁用保护模式ý
按任意键继续。 。
所以问题是if语句似乎没有被评估。我需要知道如何有条件地执行操作(如果用户按y,我计划实现代码以更新相同密钥的注册表值。)
我了解了SetLocal
和EnableDelayedExpansion
以及使用!variable!
来引用another similar question
这是我的第一个批处理文件,对我来说这一切都很新。当然,简单地告诉用户进入IE并取消选中“启用保护模式”会更容易,但任务是自动执行,同时允许用户进行一些控制(因此提示是y / n)。
答案 0 :(得分:0)
请注意,您要检查的注册表可能不存在。 只有在!ProtectedMode!中才需要检查用户输入! == 0
@echo off
setlocal enabledelayedexpansion

set /a ProtectedMode=%%a

echo ProtectedMode=!ProtectedMode!
if !ProtectedMode! == 0 (

echo.
set /P b_disable="Would you like to disable protected mode in Internet Explorer? (y/n): "
