獲取註冊表項的值

Question

我有一個批處理腳本，用於檢查註冊表項是否存在，如果存在，則打開Internet Explorer。我現在想要做的是獲取該註冊碼的值並將其放入URL中。我怎樣才能做到這一點？

@echo off 
reg query HKLM\Software\Test\Monitor\Settings 
if errorlevel 1 goto not_exist 
goto exist 

:not_exist 

:exist 
start "Test" "%ProgramFiles%\Internet Explorer\iexplore.exe" http://localhost:/dashboard.php 

謝謝大家的幫助。

在這裏，你應該自我解釋和評論。如果您有任何問題，請告訴我。

@echo off 

set THEME_REGKEY=HKLM\Software\Microsoft\Windows\CurrentVersion\Themes 
set THEME_REGVAL=ThemeName 

REM Check for presence of key first. 
reg query %THEME_REGKEY% /v %THEME_REGVAL% 2>nul || (echo No theme name present! & exit /b 1) 

REM query the value. pipe it through findstr in order to find the matching line that has the value. only grab token 3 and the remainder of the line. %%b is what we are interested in here. 
set THEME_NAME= 
for /f "tokens=2,*" %%a in ('reg query %THEME_REGKEY% /v %THEME_REGVAL% ^| findstr %THEME_REGVAL%') do (
    set THEME_NAME=%%b 
) 

REM Possibly no value set 
if not defined THEME_NAME (echo No theme name present! & exit /b 1) 

REM replace any spaces with + 
set THEME_NAME=%THEME_NAME: =+% 

REM open up the default browser, searching google for the theme name 
start http://www.google.com/search?q=%THEME_NAME%
