Submit value to html textbox with awesomium - vb.net

am using this code to split text from listbox :

For Each Item As Object In ListBox1.SelectedItems
                TextBox2.AppendText(Item.ToString + Environment.NewLine)
            Next
            Dim str As String = TextBox2.Text
            Dim leftPart As String = str.Split(":")(0)
            Dim test As String = TextBox2.Text
            Dim phrase As String = test.Substring(test.IndexOf(":"c) + 1)

and this code to submit the value to html textbox

WebControl1.ExecuteJavascript("document.getElementById('email').value=""" + leftPart + """;")
                Dim leftpar2 As String
                leftpar2 = phrase
                MsgBox(phrase)
                Try
                    WebControl1.ExecuteJavascript("document.getElementById('pass').value=""" + leftpar2 + """;")
                Catch ex As Exception
                    MsgBox(ex.ToString)
                End Try

The textbox with id (email) work fine
but the other one ( pass ) always get empty , I've tried to popup the value of ( phrase ) it get the correct value

I've tried to assign string to variable ( phrase )

Dim phrase As String = "test"

it work fine , can somebody tell me what am doing wrong ?

Solution

Well, I have download that component and went through your way

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    If (TextBox1.Text.Length < 3 Or TextBox1.Text.IndexOf(":") < 1) Then
        MsgBox("Please type value in format like {email:password}")
        Return
    End If

    ' Get the values and parse it
    Dim sources As String() = TextBox1.Text.Split(":")

    ' Now, we try to set it to page
    ' pay attention at `document.querySelector('#id')` it should be ID of the element
    WebControl1.ExecuteJavascript(String.Format("document.querySelector('#email').value = '{0}'", sources(0)))
    WebControl1.ExecuteJavascript(String.Format("document.querySelector('#password').value = '{0}'", sources(1)))
End Sub

And here's my login page code (the page which loads in WebControl component)

<body>
    <input type="email" id="email" /> 
    <input type="password" id="password" /> 
    <button id="loginButton">Login</button>
</body>

Everything seems to be working

You can run my example: drop textbox, webcontrol and button on form, set WebControl1.Source as 'http://cafe-ht.ml/fake/fake-login.html' and copy handler on button click
