Assuming /node/add/B?mainnode=5, something like this should work.

function B_form(&$node, &$params) {
  $mainnode = $_GET['mainnode'];
  // make sure it's a valid node for the purpose
  if (nid_passes_the_test($mainnode) {
    $node->mainnode = $mainnode;
  }
  else {
    // yell at them for making an error
  }
  ...
}

Earl,
  I tought about that...

  I have a ?q=node/add/B/5 and I changed the hook_form to function B_form(&$node, &$param, $nidA = 0) But I don't get the desired result... The page at drupaldocs http://drupaldocs.org/api/4.6/function/page_example_menu says that the 'extra' parameters will be passed as arguments to the function, but it seems that those don't get to the hook_form function. Is there any way to create a custom function and re-create the form as the node/add/B would do? That way I could create the form and it would work transparently to the user...
  Also, is it that the desired hook_form behavior? Have I found a bug? :-)

Thanks for the help...

You just need to get the nid of the main node into the creation of the subordinate node typoes. How about using a query string to specify the parent, like

node/add/B?mainnode=(nid of A)

or maybe

node/add/B/(nid of A)

Populate the new field in hook_form(). You can even choose to show an input control for the field if it's not specified

Hello, folks,
  I'm in need of a little help...
  I have a module with 3 types of node. Node A, B and C.
  I am trying to do something like A is the main node and B & C references A. So that, when I show the node A (teaser or full node), I get some informations about nodes type B and C that makes reference to A.
  Also, I want to node types B and C have a reference to the parent (A).
  When the user inserts the data, it must be transparent to him as who the parent is (like there is a link on node type A that allows the user to create type B or C and the node creation page will not ask the user who the parent is). The only creation method shoud be like this for nodes B and C (there should not have a link on the node creation list. Just for type A)

  I took a look at the project module, but I couldn't get much out of it...
  Any help is appreciated...

Thanks,
