One way to do this is to dynamically add hidden elements to the form with
the appropriate values and the fire the click event of a button on the
form.  Here is an example...

 Windows Form, trigger on some event:

       With Me.WebBrowser1.Document
           Dim one As HtmlElement = .CreateElement("input")
           one.SetAttribute("type", "hidden")
           one.SetAttribute("name", "one")
           one.Id = "one"
           one.SetAttribute("value", Now.ToString)
           .Forms(0).AppendChild(one)

           Dim two As HtmlElement = .CreateElement("input")
           two.SetAttribute("type", "text")
           two.SetAttribute("name", "two")
           two.Id = "two"
           two.SetAttribute("value", Now.AddDays(1).ToString)
           .Forms(0).AppendChild(two)

           .GetElementById("Button1").InvokeMember("click")
       End With


Web App:

   <form id="form1" runat="server">
   <div>
       <asp:Button ID="Button1" runat="server" Text="Button" /> <br />
       <asp:TextBox ID="TextBox1" runat="server"></asp:TextBox><br />
       <asp:TextBox ID="TextBox2" runat="server"></asp:TextBox>
       <br />
       <asp:Label ID="Label1" runat="server" Text="Label"></asp:Label>
   </div>
   </form>

and

    Protected Sub Button1_Click(ByVal sender As Object, ByVal e As
System.EventArgs) Handles Button1.Click
       If Request("one") IsNot Nothing Then Me.TextBox1.Text =
Request("one")
       If Request("two") IsNot Nothing Then Me.TextBox2.Text =
Request("two")
       Label1.Text = Now.ToString


 End Sub
