How to automatically fill in a form in IE?

[Ben Langton]

I think this is an easy question, I just can't get it to work.

I want to fill in a form (It's at this URL)
http://www.paycoinc.com/employee_tc_login.htm

and submit it. I can easily do it with Sendkeys, but that is not
reliable. I want to do it with Internet Explorer OLE Automation. This
is what I have so far, but VBScript throws "Object doesn't support this
property or method". I think it could be done by just posting the data
directly to the server, but I can't seem to get a good example of that in
VBS.

An email reply would be greatly appreciated.
Thank you in advance.

Const USER_NAME = "blahblah"
Const PASSWORD = "blahblah"
Const WEB_PAGE = "http://www.paycoinc.com/employee_tc_login.htm"
Const TITLE = "PayCo Employee Login"

Const READYSTATE_COMPLETE = 4

Dim oIE
Dim WSHShell
Dim boolActivated

'On Error Resume Next
Set WSHShell = CreateObject("WScript.Shell")

'open Internet Explorer and go to the page
Set oIE = CreateObject("InternetExplorer.Application")
oIE.Visible = True
oIE.Navigate WEB_PAGE 'opens the html page

boolActivated = WSHShell.AppActivate(TITLE)

While Not boolActivated
Wscript.Sleep 50
boolActivated = WSHShell.AppActivate(TITLE)
Wend

Do While oIE.ReadyState <> READYSTATE_COMPLETE
Wscript.Sleep 250
Loop

oIE.Document.All.ssn.Value = USER_NAME -----------> here's the error

'oIE.Quit
Set oIE = Nothing
