VBScript Sleep

I’ve just had a requirement for a sleep command in ASP, apparently there isn’t one (not that I can find). There is a Wscript.Sleep for command line VBS’s but nothing in ASP.

So, I’ve written a really quick simple one that some might find useful –

Sub Sleep(intSecs)
Dim dtStart, boolDone
dtStart = now()
boolDone = False
While Not boolDone
If DateDiff("s",dtStart,now()) >= cint(intSecs) Then
boolDone = True
End If
End Sub

Update: As noted in the comments, this really *shouldn’t* be used as it pins your CPU. If you must use it, please be aware of what it’s doing.

    Thanks for your comment DJ, to be honest I’ve not used this one (or had a need for it) in ages. Do you have a way that doesn’t pin the CPU? I’ll have a think.. (I don’t really do much classic ASP anymore).

    Yeah, I’m sorry, but dj is right. While this technique works in theory, it’s a very bad idea in practice.

    Although it works, it’ll force your CPU (or core) usage up to 99 or 100%, ironically when the code is meant to be doing *nothing*! Very strongly NOT recommended.

    It’s a PITA that classic ASP doesn’t appear to have a proper Sleep command.
