Wait .5 seconds before continuing code VB.net

Question

I have a code and I want it to wait somewhere in the middle before going forward. After the WebBrowser1.Document.Window.DomWindow.execscript("checkPasswordConfirm();","JavaScript") I want it to wait .5 seconds and then do the rest of the code.

    WebBrowser1.Document.Window.DomWindow.execscript("checkPasswordConfirm();","JavaScript")

    Dim allelements As HtmlElementCollection = WebBrowser1.Document.All
    For Each webpageelement As HtmlElement In allelements
        If webpageelement.InnerText = "Sign Up" Then
            webpageelement.InvokeMember("click")
        End If
    Next

Answer 1

You'll need to use System.Threading.Thread.Sleep(number of milliseconds).

WebBrowser1.Document.Window.DomWindow.execscript("checkPasswordConfirm();","JavaScript")

Threading.Thread.Sleep(500) ' 500 milliseconds = 0.5 seconds

Dim allelements As HtmlElementCollection = WebBrowser1.Document.All
For Each webpageelement As HtmlElement In allelements
    If webpageelement.InnerText = "Sign Up" Then
        webpageelement.InvokeMember("click")
    End If
Next
