[omniORB] Looking for examples of sequence manipulation

[Perham, David A. (Mission Systems)]

Thanks for the post. 

I must still be doing something wrong.

This is a sample of the code I am trying to implement:

// IDL

typedef sequence <EntityInventoryType, 10> EntityInventorySequence ;

// Impl

bool ObjectServerImpl::RequestEntityInventory( long EntityId,				                    EntityInventorySequence_out	 EntityInventory ) 
{
	EntityInventorySequence*& ptr =  EntityInventory.ptr() ;
      (*ptr)[0].InventoryCode = 5 ;
}

This builds, however I am not very confident that it is correct, because the .NET intellisensor tool is not filling out the "InventoryCode" when I type "(*ptr)[0].".

Am I still missing something?

Thanks again for the help, I still haven't found any examples on the net.

Take care

(*ptx)[0].x = 29;

for example

and if you want to populate all the sequence

for (CORBA::ULong i = 0; i < ptx->length(); i++) {
	(*ptx)[i].x = ...;
	(*ptx)[i].y = ...;
}

I expect this helps you.

Cheers.
