C++builder編程修改註冊表的問題

RootKey是註冊表的根索引值,比如運行regedit後看到的HKEY_USERS,HKEY_LOCAL_MACHINE就是RootKey,在TRegIniFile中預設的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;

   //改變預設Rootkey

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

                Version\\Run",true)) //開啟主鍵

   //這樣雙引號裡面的東西就變成了CurrentKey

   {

     Application->MessageBox("註冊表內容無效",

                 "讀取註冊表出錯",MB_ICONERROR);

     MyRegistry->CloseKey();

     delete MyRegistry;

     return;

    }

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

  MyRegistry->CloseKey();

  delete MyRegistry;
