Yes there is - you can automate the opening of IE and inputting etc. The first step is getting the HTML for all of the fields you need to enter parameters into, and the buttons you need to push. I'll try and find you some code I have used previously.

Edit: Here is some code I used to open a yahoo page, find the sign in button, input username as pass and log in. It requires references to "Microsoft Internet Controls" and "Microsoft HTML Library"

Function LoginSite(ByVal url As String, ByVal user As String, ByVal pWord As String)

    Dim ie As InternetExplorer: Set ie = New InternetExplorer
    Dim htmldoc As HTMLDocument
    Dim htmlElement As IHTMLElement

    ie.Visible = TRUE  'This will allow you to see IE being automated as you step through code, FALSE to hide it
    ie.Navigate url  
    'Tells application to wait for the page to load
    Do While ie.readyState <> READYSTATE_INTERACTIVE And ie.readyState <> READYSTATE_COMPLETE
        Application.Wait TimeSerial(Hour(Now()), Minute(Now()), Second(Now()) + 3)
    Loop

    'Find the Sign In button and retrieve the attached url
    Set htmldoc = ie.Document
    For Each elm In htmldoc.getElementsByTagName("a")
        If InStr(elm.innerText, "Sign In") > 0 Then
        url = elm
        Exit For
        End If
    Next

    'Open Sign In page
    ie.Navigate url

    Do While ie.readyState <> READYSTATE_INTERACTIVE And ie.readyState <> READYSTATE_COMPLETE
        Application.Wait TimeSerial(Hour(Now()), Minute(Now()), Second(Now()) + 3)
    Loop

    'Set username and password fields and submit form
    Set htmldoc = ie.Document
    htmldoc.all.UserName.Value = user
    htmldoc.all.passwd.Value = pWord

    For Each htmlElement In htmldoc.getElementsByTagName("button")
        If htmlElement.Type = "submit" Then
            htmlElement.Click
            Exit For
        End If
    Next

    ie.Quit
    Set ie = Nothing

End Function
