关于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;
