Cannot InvokeMember on HTML Page

[sge]

I have a VB Net application that I have been running for over a year to login to a specific website

Heritage Coins & Currency

The page I'm now unable to loging is --> https://coins.ha.com/c/login.zx

I am setting the text boxes as follows:
WB1.Document.All("emailAddress").SetAttribute("Value", "sge")
WB1.Document.All("password").SetAttribute("Value", "7476")

Even though these values do actually display on the screen when I do GetAttribute I see that I have set the values.
?WB1.Document.All("emailAddress").getAttribute("Value")
"sge"
?WB1.Document.All("password").getAttribute("Value")
"7476"

When i do InvokeMember as follows NOTHING HAPPENS and I receive no msgs
WB1.Document.GetElementById("loginButton").InvokeMember("click")

The HTML code smippet is:
<input id="loginButton" name="loginButton" value="Sign-In" type="submit" tabindex="3">&nbsp;&nbsp;
<input name="source" type="hidden" value="" />
<input name="forceLogin" type="hidden" value="" />

<input name="loginAction" value="log-in" type="hidden">

I am an inexperienced Net programmer and I do not have a clue how to resolve

thanks

WB1.Document.GetElementById("loginButton").InvokeMember("click")

Works perfectly for me. Are you sure that the page is fully loaded when you run the invoke?

Yes the page is fully loaded.

Are you going to the next page where just below the picture at the top to the right of center

it should say "Welcome Sandy (Sign-Out)" This is what I am expecting.

I get Welcome xxxx (Sign-In) which indicates the Login did not work

Seems like it takes a hammer to crack this nut. This is the only reliable method I could find ....

Private Sub Whatever()
        'whatever you do to make sure the page is fully loaded
        Go()
        Timer1.Start() 'tick 2000 possibly adjustable
    End Sub
 
    Private Sub Go()
        SendKeys.Send("sge") ' seems brute force and ignorance is needed!
        SendKeys.Send(Chr(9))
        SendKeys.Send("7476")
        SendKeys.Send(Chr(9))
        WB1.Document.GetElementById("loginButton").InvokeMember("click") 'first time confirms
    End Sub
 
    Private Sub Timer1_Tick(sender As System.Object, e As System.EventArgs) Handles Timer1.Tick
        Timer1.Stop()
        Go() 'second time's the charm
    End Sub
