WUCheck.exe question

[NewsArchive]

Hi Friedrich,

What happens if there is no internet connection available when wucheck.exe
runs? Does it time out immediately or does it wait for some period of time?
Same question regarding if the server is not accessible. I don't see
anything in the help about what happens if it fails...

Best regards,

wupdate.exe would report a Network Communication Error in this case (see
attached screenshot). The last 5 digits represent the received WinSock
error code.

The first four digits represent an internal HTTP component error ID:

Hi Arnór,

BTW, because wucheck.sb7 is based on wupdate.sb7 (source codes located in
the Redist folder), the WUCheck.exe client displays the same error codes.

If your own application "waits" for a return value from WUCheck.exe, it
receives -2 or -4 (depends on the method you uses) if the client is unable
to download the manifest file from the server.

Thanks for the information and the link:) What about the time it takes? Is
it immediate (or relatively immediate) or is there a timeout on this? I
have a customer who is looking to implement wucheck.exe but is concerned
that it may cause delays or even lock up his system if he runs it and lets
his program wait for it.

Best regards,

There is no defined timeout (in the wucheck.exe and/or wupdate.exe clients).
When the Winsock API returns, the client displays the error immediately (or
returns an error code to your application). I have never seen any delay in
all the years on our systems (from Win95 up to Win2008 R2).

Yep, that's what I thought:) I played a bit with wininet tonight and when
trying to access a non-existing (ftp) server it returned in < 1sec with an
error and I'd presume winsock is the same.

Thanks much for the information, I will send this to my customer:)
