How can I add this value to the Registry?

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control]
"myMap"=hex:00,00,00,00,5b,e0,00,00,5c


I try this but it won't work
regKey->WriteBinaryData("myMap",(char *)new_binary,sizeof(new_binary));
regKey->CloseKey();
This add a different value

Always provide more information besides "it won't work".  Mention any 
exceptions, compilation errors, etc.

What value does it add?

You need to show more of your code.  Nobody here knows how 'new_binary' has 
been defined.

However, this should work just fine (not tested):

  char new_binary[9] = { 0, 0, 0, 0, 0x5b, 0xe0, 0, 0, 0x5c };

  TRegistry* reg = new TRegistry(KEY_ALL_ACCESS);
  std::auto_ptr<TRegistry> auto_reg(reg); // RAII
  reg->RootKey = HKEY_LOCAL_MACHINE;
  if (reg->OpenKey("SYSTEM\\CurrentControlSet\\Control", true))
  {
    reg->WriteBinaryData("myMap", new_binary, sizeof(new_binary));
  }
