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;
