title: MFC Resource ID uniqueness
body: <p>This is basically an extension of the question <a href="https://stackoverflow.com/questions/17428109/mfc-resource-ids-uniqueness">here</a>.</p>
  
  <p>I am working on an old MFC application where it seems the resource.h file has been manually edited and has gone messy. I see that there are conflicting IDs in there.</p>
  
  <p>I just want to confirm if we can have two resources with the same ID of different type. 
  For example, I have something like</p>
  
  <pre><code>IDD_1     101
  IDS_2     101
  </code></pre>
  
  <p>or </p>
  
  <pre><code>IDR_1     102
  IDS_2     102
  </code></pre>
  
  <p>Basically, there are resources defined with the same ID, but of different types.</p>
  
  <p>A comment to the original question says that <code>Resources of the same type don't share identifiers</code>. If that is true, is it also valid for the <code>IDR_xxxx</code>IDs?</p>
  
  <p>I am asking because I am using the <a href="http://www.riverblade.co.uk/products/resorg/index.html" rel="nofollow noreferrer">Resource ID Organiser</a> which seems to think that all IDs must be unique.</p>
