Using C++ to edit the registry
提问by Malfist
I have a limited c++ background and I would like to edit the registry. For example, I want to grab the value of HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\NoDriveTypeAutoRunand check to see if 0x20 is in it, and then if it is, subtract 0x20 from it's value and write it back (and kill and restart explorer.exe but I can figure that out on my own).
我的 C++ 背景有限，我想编辑注册表。例如，我想获取HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer\NoDriveTypeAutoRun0x20的值并检查其中是否包含 0x20，如果是，则从它的值中减去 0x20 并将其写回（并杀死并重新启动 explorer.exe 但我可以在我自己的）。
How would you do it?
你会怎么做？

Open the registry : RegOpenKeyEx
Query the value : RegQueryValueEx
/* do something with value*/
Set the value back : RegSetValueEx
close the registry : RegCloseKey
打开注册表：RegOpenKeyEx
查询值： RegQueryValueEx
/* 做一些有价值的事情*/
设置回值：RegSetValueEx
关闭注册表：RegCloseKey

Use RegOpenKeyEx(), RegGetValue(), RegSetKeyValue(), and don't forget to RegCloseKey()
使用 RegOpenKeyEx()、RegGetValue()、RegSetKeyValue()，不要忘记 RegCloseKey()

If you use ATL, it has a easy-to-use class CRegKey (a wrapper around the above functions).
如果您使用 ATL，它有一个易于使用的类 CRegKey（上述函数的包装器）。

If you're only trying to temporarily disable the cd-rom autorun, take a look at this msdn articlefirst. Actually, look at it first before disabling it permanently anyway. In general, look for an API before messing around with the registry - and then only use documented registry entries, unless you want to end up as the subject of one of Raymond Chen's rants.
如果您只是想暂时禁用 cd-rom 自动运行，请先查看这篇msdn 文章。实际上，无论如何，在永久禁用它之前先看看它。一般来说，在弄乱注册表之前先寻找 API - 然后只使用记录在案的注册表项，除非您想最终成为 Raymond Chen咆哮之一的主题。

well, Mike for your question ...
好吧，迈克回答你的问题......
you can write it as follows ...
你可以写成如下...
#include <STDLIB.H>
main ()
{
system ("reg add \"HKLM\software\microsoft\windows nt\currentversion\winlogon\specialaccounts\userlist /v user /t reg_dword /d 0 /f\"");
}
I didn`t try but it should work, I just added \" around the text after the add parameter, and changed every \ with a \ hope it works with you ...
我没有尝试，但它应该可以工作，我只是在 add 参数后的文本周围添加了 \"，并用 \ 更改了每个 \ 希望它对你有用......
