I don't have any code that does this, but this is how I understand  
one would go about this.  First of all to simplify the task, tag all  
the cells of your notebook that contain expressions you wish to  
evaluate with something unique then:

- From your Mathlink program issue a NotebookOpen 
["YourNotebookFileName",Visible->False] this will return a  
NotebookObject.

- Issue a SetSelectedNotebook[NotebookObject] where NotebookObject is  
the result of the previous expression.

- Issue a NotebookLocate[YourTag] this sets the selection to be all  
the cells of interest.  If you did not tag the cells you will have to  
select each cell of the notebook in turn, examine its contents and  
evaluate it if necessary, the commands to do this are described in  
the Built-in Functions->Notebooks->Notebook Operators and Built-in  
Functions->Notebooks->Notebook Manipulations sections of the Help  
Browser.

- Issue a SelectionEvaluateCreateCell[NotebookObject] where the  
NotebookObject is the result of the first command.

You should now be able to issue commands for the expressions defined  
in your notebook as with any other Mathematica expression.  You can  
issue a NotebookClose when you're done.

Hope this helps,

Ssezi
