I am trying to use this:
While xxxxxx <> 0
    System.Runtime.InteropServices.Marshal.ReleaseComObject(xxxxxx)

I am trying to execute this statement just before I exit a COM class.  Is xxxxxx the Com class name?  Can I release it when I am still in it?

Can you provide a while loop where xxxxxx = the com clas name and is the only COM component

Unless I am missing something, xxxxxx is a variable holding a reference to your COM object. When in your While loop, you are not "in" the COM. Your COM object exists regardless of your loop. Your loop is saying "keep trying to release (ReleaseComObject) this object until the variable xxxxxx points to 0 and not to a COM object."

I would like to clarify a little

Suppose there is a COM Class in a class library and it has been installed on your pc.  The method called in the class begins

Public Function Broker(ByVal extensionData As thirdparty..IFaExtensionData)

(    all kinds of code)


System.Runtime.InteropServices.Marshal.ReleaseComObject(extensionData)

end Function

My question is:  Is this necessary?  Is this the correct way to use it, if it is necessary?
