I found a solution:
Code:
Imports System
Imports System.Windows.Forms
Imports System.Security.Permissions
<PermissionSet(SecurityAction.Demand, Name:="FullTrust")> <System.Runtime.InteropServices.ComVisibleAttribute(True)> Public Class Form1
Inherits Form
Private webBrowser1 As New WebBrowser()
Private WithEvents button1 As New Button()
<STAThread()> _
Public Shared Sub Main()
Application.EnableVisualStyles()
Application.Run(New Form1())
End Sub
Public Sub New()
button1.Text = "call script code from client code"
button1.Dock = DockStyle.Top
webBrowser1.Dock = DockStyle.Fill
Controls.Add(webBrowser1)
Controls.Add(button1)
End Sub
Private Sub Form1_Load(ByVal sender As Object, ByVal e As EventArgs) Handles Me.Load
webBrowser1.AllowWebBrowserDrop = False
webBrowser1.IsWebBrowserContextMenuEnabled = False
webBrowser1.WebBrowserShortcutsEnabled = False
webBrowser1.ObjectForScripting = Me
' Uncomment the following line when you are finished debugging.
'webBrowser1.ScriptErrorsSuppressed = True
webBrowser1.DocumentText = _
"<html><head><script>" & _
"function test(message) { alert(message); }" & _
"</script></head><body><button " & _
"onclick=""window.external.Test('called from script code')"" > " & _
"call client code from script code</button>" & _
"</body></html>"
End Sub
Public Sub Test(ByVal message As String)
MessageBox.Show(message, "client code")
End Sub
Private Sub button1_Click(ByVal sender As Object, ByVal e As EventArgs) Handles button1.Click
webBrowser1.Document.InvokeScript("test", New String() {"called from client code"})
End Sub
End Class
Invoke Function or Sub from html button input
