title: Check Value of .NET Handle ^
body: <p><strong>Here's my situation:</strong></p>
  
  <p>I have .NET wrapper-objects in a C++/CLI layer that hold pointers to unmanaged C++ objects. I've implemented the finalizer so that it deletes the unmanaged memory pointed to by the wrapper-object on garbage-collection and sets the pointer to null.</p>
  
  <p><strong>Here's the problem</strong>:</p>
  
  <p>I'm watching the finalizer for the .NET wrapper-object and it gets called twice and tries to delete the same memory twice, indicating that I have somehow created 2 .NET wrapper objects that go out-of-scope, and are garbage collected while I'm still expecting the wrapper object to be in scope (these wrapper objects are getting passed to a VB.NET application).</p>
  
  <p><strong>Here's my question:</strong></p>
  
  <p>Is there anyway for me to check the handle value so that I can confirm where the wrapper objects are getting created (copied or whatever)? Currently I'm looking at the handle values (EG - 0x0014fe80), but I see 3 different values for when the object is created, added to a collection, and deleted. So I'm not sure if the GC is just moving stuff around and this is the same object, or if I'm actually seeing 3 different objects that reference the same unmanaged memory. I would like to resolve the duplicate object copies if possible, but I understand that I will probably want to implement some sort of smart pointer so that this doesn't happen.</p>
  
  <p>Thanks,
  Ian</p>
