title: problem convert idl to tlb
body: <p>i try to get a selected text and the word under mouse in firefox</p>
  
  <p>after a lot of search i get the solution that i must  access a document's HTML in Firefox using IAccessible</p>
  
  <p>i found that solution in c++ in this link 
  <a href="https://stackoverflow.com/questions/542395/how-to-access-a-documents-html-in-firefox-using-iaccessible">How to access a document&#39;s HTML in Firefox using IAccessible</a></p>
  
  <p>the solution use ISimpleDOMNode.idl file so the first step to convert that solution from c++ to c# is convert </p>
  
  <p>ISimpleDOMNode.idl to tlb file and convert tlb to dll fill</p>
  
  <p>i try to use VS Command Prompt with this command to convert to tlb file
  midl ISimpleDOMNode.idl</p>
  
  <p>but That generate ISimpleDOMNode.h and ISimpleDOMDocument.h, which define the interfaces. It also create ISimpleDOMNode_i.c and ISimpleDOMDocument_i.c   but there is no tlb file</p>
  
  <p>what is the wrong ?</p>
