非管理员模式下的注册表访问 [英] Registry access in non-admin mode

问题描述

我在Delphi中编写了几个长期存在的应用程序，将其设置保存在注册表中。我使用HKEY_LOCAL_MACHINE硬设置，如配置首选项和HKEY_CURRENT_USER软信息，如窗口位置，MRU列表等。

现在我的用户告诉我认为，在非管理员（标准用户）模式下，应用程序不起作用。看，我看到当应用程序处于管理模式时，我无法读取放入HKEY_LOCAL_MACHINE的设置。

我有什么选择？我对标准模式知之甚少，这对于访问注册表的方式有何影响。任何信息赞赏。

解决方案

您可以从HKLM读取为非管理员用户;你不能写信。

在构建它时使用TRegistry.Create（KEY_READ），并将RootKey设置为HKLM。

  var 
注册表：TRegistry; 
 begin 
注意：= TRegistry.Create（KEY_READ）
 try 
 Reg.RootKey：= HKLM; 
 //读取值在这里
 finally 
 Reg.Free; 
结束
结束
  

打开特定注册表项时也可以使用TRegistry.OpenKeyReadOnly（）这有助于非管理员访问注册表的区域。

I've several long-standing apps written in Delphi that persist their settings in the registry. I've used HKEY_LOCAL_MACHINE for 'hard' settings such as configuration preferences and HKEY_CURRENT_USER for 'soft' info such as window positions, MRU lists etc.

Now my users are telling me that in non-admin (standard user) mode the apps dont work. Looking, I see that I'm not able to read a setting put into HKEY_LOCAL_MACHINE when the app was in admin mode.

What are my options for this? I know little about standard mode and how this affects access to the registry at all. Any info appreciated.

解决方案

You can read from HKLM as a non-admin user; you just can't write to it.

Use TRegistry.Create(KEY_READ) when constructing it, and set the RootKey to HKLM.

var
  Reg: TRegistry;
begin
  Reg := TRegistry.Create(KEY_READ)
  try
    Reg.RootKey := HKLM;
    // Read value here
  finally
    Reg.Free;
  end;
end;

You can also use TRegistry.OpenKeyReadOnly() when opening a specific registry key; this helps with non-admin access to areas of the registry as well.
