How can I handle this error in vbscript? I want to catch this error and show msgbox with my error, i.e. web page is not available. vbscript xmlhttprequest share|improve this question edited Jul 21 http error codes '14 at 11:29 panther 14.2k71943 asked Jul 21 '14 at 11:28 Michael 6481717 OK, msxml2, not 12 it was just a typo... this script runs OK, when the web page exists –Michael Jul 21 '14 at 12:45 add a comment| 2 Answers 2 active oldest votes up vote 3 down vote accepted There are at least three possible points of failure in your script. CreateObject may fail; e.g. if you use msxml12 (digit 1) instead of msxml2 (letter l). Such blunders should be fixed during development. .Open may fail; e.g. if you use "mysite.com" instead of a syntactically correct URL. If you get the URL at runtime, a 'look before you jump' check is advisable, an OERN can be used to catch bad URLs not found by your validation. .Send may fail; e.g. if the site is down or abandoned. This is a clear case for an OERN. The most important rule wrt OERN: Keep it local and short (Only one risky line between OERN and OEG0). Demo code: Option Explicit Dim sUrl For Each sUrl In Split("http://stackoverflow.com http://pipapo.org mysite.com") Dim oXML, aErr ' Set oXML = CreateObject("msxm12.XMLHTTP") Set oXML = CreateObject("msxml2.XMLHTTP.6.0") On Error Resume Next oXML.Open "GET", sUrl, False aErr = Array(Err.Number, Err.Description)

Scripting > The Official Scripting Guys Forum! Question 0 Sign in to vote We have a small VB6 program that uses XMLHTTP object to send some form data back to the server. In addition, we were attempting to use the 6.0 version of the MSXML routines. It seems that is the version recommended. Everything works fine if we use the "GET" method and add the parameters to http://stackoverflow.com/questions/24863986/vbscript-msxml12-xmlhttp-error-handling the end of the URL. However, when using the "POST" method we keep getting "invalid parameter" when call the "send" method with the parameter list as the message body in the "send". Interestingly if we use the previous versions of XMLHTTP everything works great with either a "POST" or a "GET". What are we missing here? Is there some API change to the https://social.technet.microsoft.com/Forums/scriptcenter/en-US/a2887fc4-90a6-4f27-9678-b76137f3cb22/invalid-parameters-when-using-xmlhttp60-and-post-method?forum=ITCG "send" parameter we are overlooking? For reference the code is quite simple: Dim objXMLRequest As Object Dim BodyOfRequest as String BodyOfRequest = "state=" & URLEncode(State) _ & "&sq=" & URLEncode(SequenceNumber) Set objXMLRequest = CreateObject("MSXML2.XMLHTTP.6.0") Call objXMLRequest.open("POST", BaseURL , False) Call objXMLRequest.setRequestHeader("Content-Type", "application/x-www-form-urlencoded") objXMLRequest.setRequestHeader "User-Agent", "Mozilla/4.0 (compatible; MSIE 7.0; Windows NT 6.0)" call objXMLRequest.send (BodyOfRequest) If we change to "MSXML2.XMLHTTP.3.0" it works. Searches on this problem have come up pretty empty. So hopefully someone has an idea. Thanks in advance for your help. It is appreciated.

Maybe the 3.0 code performs a typecast and the 6.0 does not. Of course, I would have expected that to cause a "type mismatch" error, but ... It wouldn't take much to change the type to Vari
