Adding a registry key in windows with quotes needed in the data using a batch script
提问by Trey
Little Willis here. I am trying to using a batch script to edit an existing registry key that is used when double clicking a .jar file. The issue is that the data that I'm trying to enter contains quotes but I also need quotes for it to be considered a string.
小威利斯来了 我正在尝试使用批处理脚本来编辑双击 .jar 文件时使用的现有注册表项。问题是我尝试输入的数据包含引号，但我也需要引号才能将其视为字符串。
Example:
例子：
reg add "HKEY_LOCAL_MACHINE\Software\Classes\jarfile\shell\open\command" /v "" /t REG_EXPAND_SZ /d "C:\Program Files\Java\jre7\bin\javaw.exe" -jar "%1" %* /f
When I run that in a batch script the cmd window prints out "Error: Too many command line parameters"
当我在批处理脚本中运行它时，cmd 窗口会打印出“错误：命令行参数太多”
So to make this simple. I want to add a registry key with "C:\Program Files\Java\jre7\bin\javaw.exe" -jar "%1" %* as the data including the quotations and the %1 and %* exactly as they are not converted to any actual statement or string.
所以为了让这一切变得简单。我想添加一个带有 "C:\Program Files\Java\jre7\bin\javaw.exe" -jar "%1" %* 的注册表项作为包括引号和 %1 和 %* 的数据未转换为任何实际语句或字符串。
EDIT:
编辑：
The registry is normally added using using this command line string:
通常使用以下命令行字符串添加注册表：
ftype jarfile="C:\Program Files\Java\jre7\bin\javaw.exe" -jar "%1" %*
it works fine in the command line, but just as the code given below when I used this in a batch script the "%1" and %* don't appear.
它在命令行中工作正常，但正如下面给出的代码一样，当我在批处理脚本中使用它时，“%1”和 %* 不会出现。

Use backslashes to escape the inner quotes, i.e.:
使用反斜杠来转义内部引号，即：
reg add "HKEY_LOCAL_MACHINE\Software\Classes\jarfile\shell\open\command" /v "" /t REG_EXPAND_SZ /d "\"C:\Program Files\Java\jre7\bin\javaw.exe\" -jar \"%1\" %*" /f

Percent literals must be doubled in a batch file: \"%%1\" %%*"
百分比文字必须在批处理文件中加倍： \"%%1\" %%*"

as an addition to dbenham's answer, you should use backslaches and quotes for location path !!
(i mean, you should use "\"C:\Program Files.....instead of "C:\Program Files.....)
作为dbenham答案的补充，您应该对位置路径使用 backslaches 和引号！！
（我的意思是，你应该使用"\"C:\Program Files.....而不是"C:\Program Files.....）
so this is the final answer for typical percent sign &adding problem:
所以这是典型百分号&添加问题的最终答案：
reg add "HKEY_LOCAL_MACHINE\Software\Classes\jarfile\shell\open\command" /v "" /t REG_EXPAND_SZ /d "\"C:\Program Files\Java\jre7\bin\javaw.exe\" -jar \"%%1\"" /f
thanks dbenham!
谢谢德本汉姆！

Another alternative is to use single quotes, some applications can read it properly, example:
另一种选择是使用单引号，一些应用程序可以正确读取它，例如：
reg add "HKEY_LOCAL_MACHINE\Software\Classes\jarfile\shell\open\command" /v "" /t REG_EXPAND_SZ /d "'C:\Program Files\Java\jre7\bin\javaw.exe\' -jar '%1' %*" /f
