copied!<p><strong>NO.</strong> You can try, you can hope but there is <strong><em>no guarantee</em></strong> in order of calling initialization and finalization. See <a href="http://qc.embarcadero.com/wc/qcmain.aspx?d=72245" rel="nofollow noreferrer">qc72245</a>, <a href="http://qc.embarcadero.com/wc/qcmain.aspx?d=56034" rel="nofollow noreferrer">qc56034</a> and <a href="http://www.google.com/search?q=unit+initialization+order+site%3Aqc.embarcadero.com" rel="nofollow noreferrer">many more</a>.</p> <p><strong>UPDATE:</strong></p> <ol> <li>finalization section is executed in reverse order than initialization. Your example is safe, you don't have dependency on calling initialization sections between units</li> <li>Delphi can mix calling units (point 1 is still valid, both initialization and finalization sections are swapped)</li> </ol> <p>Example:</p> <pre><code>unitA // no dependency on unitB var SomeController; initialization SomeController := TSomeController.Create; finalization SomeController.Free; unitB uses unitA; initialization SomeController.AddComponent(UnitBClass); finalization SomeController.RemoveComponent(UnitBClass); </code></pre> <p>Common (correct) order (99.99%) of calling:</p> <ol> <li>unitA.initialization</li> <li>unitB.initialization</li> <li>run...</li> <li>unitB.finalization</li> <li>unitA.finalization</li> </ol> <p>But <em>sometimes</em> can Delphi compile file wrong:</p> <ol> <li>unitB.initialization - AV here</li> <li>unitA.initialization</li> <li>run...</li> <li>unitA.finalization</li> <li>unitB.finalization - and here too</li> </ol> <p>Little offtopic story:</p> <p>We have quite big project, with Type1 in Unit1, Type2 = class(Type1) in Unit2. Files are ordered in project.dpr and after years and adding Unit200 (<em>no dependency with unit1/2</em>) Delphi starts compiling project with Unit2.Initialization before Unit1.Initialization. Only safe solution is calling your own Init functions from initialization section.</p>
