I am going to enumerate not installed updates with Windows Update Agent. And I have one question. Is that a way to discard/stop BeginSearch method (searching process). I have tried to stop search process with EndSearch but it does not stop it. Thanks.

  • How do you know EndSearch doesn't stop the search? What happens? What does EndSearch return? – andlabs Sep 01 '16 at 16:25
  • EndSearch does not return. Program just stops on EndSearch and waits until process is completed. Is that correct behavior? – Space Rabbit Sep 01 '16 at 16:31

    Given that you get an ISearchResults out of it, I assume the answer is yes; look into ISearchJob::RequestAbort()? (Call it first, then EndSearch(), then release the ISearchResults as that should just give you a ResultCode of orcAborted... Follow the documentation's hyperlinks =P ) – andlabs Sep 01 '16 at 16:33
  • Thanks man. This is what i need!!! – Space Rabbit Sep 01 '16 at 16:39

IUpdateSearcher::EndSearch() waits for the search to complete first. You can explicitly request the search to stop early by first calling ISearchJob::RequestAbort() on the ISearchJob you get from IUpdateSearcher::BeginSearch(). After doing that, the ISearchResults returned from EndSearch() should have a ResultCode of orcAborted, and you should be safe with just releasing it. (You should still call EndSearch(), because the abort operation is still asynchronous, as hinted by the name "request abort".)
