below code works fine if I open one application with eo.webbrowser, but cannot working(cannot get the gethtml) if two applications(as long as they are both use eo.webrowser) opened in the same computer at the same time. Could you please help me to solve it?

Public Function gethtml(url As String) As String
gethtml = ""

Try

Dim options As New EO.WebEngine.WebViewOptions()
options.AllowJavaScript = False
options.LoadImages = False
EO.WebEngine.EngineOptions.Default.SetDefaultWebViewOptions(options)
Catch ex As Exception

End Try

Dim threadRunner As New ThreadRunner()
Dim WebView As WebView = Nothing

Try

WebView = threadRunner.CreateWebView()


AddHandler WebView.CertificateError, Sub(sender As Object, e As CertificateErrorEventArgs)
e.Continue()
End Sub

threadRunner.Send(Sub()
Try
WebView.LoadUrlAndWait(Trim(url))
gethtml = WebView.GetHtml()
Catch ex As Exception

End Try
End Sub)

Catch ex As Exception

Finally

If WebView IsNot Nothing Then
Try : WebView.Dispose() : Catch : End Try
End If

If threadRunner IsNot Nothing Then
Try : threadRunner.Dispose() : Catch : End Try
End If
End Try



End Function

Sorry. I spend 3 hours test my code carefully,there is no problem with your EO.webbrowser or my code, its the web problem,thanks.
