xmlhttprequest async parameter

[Laeg]

So I have a db table with two fields, the first field is filled by a call to an external page via xmlhttprequest object and the second field is filled by a script function.
The problem is that although I have set the open method async parameter to false my script still does not wait until processing is finished on foo() function and executes boo(). How can I get the xmlhttprequest object to wait? Any ideas???

While(some condition)
...
foo(foobarid)
bar(foobarid)
Wend

Function foo(foobarid)
' Fills field A
Set objHTTP = CreateObject("Microsoft.XMLHTTP")
objHTTP.open "POST", "

http://www.foobar.com",

False
objHTTP.setRequestHeader "Content-Type", "application/x-

http://www-form-urlencoded"

objHTTP.send "foobarid=" & server.URLEncode(foobarid)
Set objHTTP = Nothing
End Function

Function bar()
' Fills field B
End Function

That looks more like AVAX code, than AJAX. You might wanna try asking in the VBScript forum.

And why not just add bar() into the callback function ? - then it will only fire when/if the foo() function finishes and responds back to the client. using synchronous requests can freeze up the users browser, async is much kinder to the usability of your site.

in fact.. looking at your code... this is server side isn't it? In which case you want to use the server version of the xmlhttprequest.. not the client version as you have here. >> server.createobject("MSXML2.ServerXMLHTTP.4.0").
