关于C++builder编程修改注册表的问题

发布时间:2006-05-03 11:43:30来源:红联作者:爱的边缘
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;
