C++builder编程修改注册表的问题

RootKey是注册表的根键值,比如运行regedit后看到的HKEY_USERS,HKEY_LOCAL_MACHINE就是RootKey,在TRegIniFile中缺省的RootKey
是HKEY_USERS.

下面的例子是TRegistry的,TRegIniFile也差不多

void __fastcall TfrmMainForm::WriteToMyRegistry(int table_count)

{

  //TODO: Add your source code here

  TRegistry *MyRegistry=new TRegistry;

  MyRegistry->RootKey=HKEY_LOCAL_MACHINE;

   //改变缺省Rootkey

  if(!MyRegistry->OpenKey("Software\\Microsoft\\Windows\\Current\

                Version\\Run",true)) //打开主键

   //这样双引号里面的东西就变成了CurrentKey

   {

     Application->MessageBox("注册表内容无效",

                 "读取注册表出错",MB_ICONERROR);

     MyRegistry->CloseKey();

     delete MyRegistry;

     return;

    }

  MyRegistry->WriteString("myrun","c:\\sthvcd\\sthvcd.exe");

  MyRegistry->CloseKey();

  delete MyRegistry;
