| 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;
