Vb.net document.getelementbyid() not working with chromium

The new code I tried didn't seem to work so I'm looking for guidance on how my VB code setup for an IE browser can be converted to work in Chromium:

Code:

---

Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
    Value.Text = Value.Text - 1

    If Value.Text = 0 And
        WebBrowser1.DocumentText.Contains(User.Text) Then

        WebBrowser1.Document.GetElementById("msg").InnerText = R1.Text
      WebBrowser1.Document.GetElementById("submit").InvokeMember("Click")
        Value.Text = 240
        LatestActivity.Text = (DateTime.Now.ToString())

    End If
End Sub

---

The new code I've started with is simply:

Code:

---

browser.ExecuteScriptAsync("document.GetElementById('message').InnerText;" = R1.Text)

---

But I unfortunately had no luck with it so any guidance is greatly appreciated.

This code:

vb.net Code:

browser.ExecuteScriptAsync("document.GetElementById('message').InnerText;" = R1.Text)

is equivalent to this:

vb.net Code:

Dim flag As Boolean = ("document.GetElementById('message').InnerText;" = R1.Text)
 
browser.ExecuteScriptAsync(flag)

That's clearly not what you want. I'm guessing that you actually want to execute that script and get the text result, then compare that to R1.Text, so do that. Also, if you're calling ExecuteScriptAsync then that's going to return a Task, so you probably need to await it or get the Result. You ought to look at existing examples of that method and see how they do it.

Thanks for your answer. I had the original code working fine with the built-in IE browser, but that only lasted so long since it's quite outdated by now. Is there a simpler way I can just translate my original code to work with Chromium?

Bump, still looking for assistance. TIA.
