VB.NET pas textbox value in windows form to textbox in ASP page

Question

I currently develop a POS system with VB.NET 2017. In the form I work on (called frmProcessCheckOut), I have a textbox where the user enters the amount to charge on Visa. I have an ASP page that has a textfield as well. Is there a way to have a button on the windows form that when I click on it, it puts the value of the textbox in the textfield of the ASP page?

Thank you.

Answer 1

I would do it this way.

1) In Button Click Event , I will trigger the Internet Explorer process as the same time opening my website URL and passing the text value into web parameter, ex. refID

Private Sub Button1_Click(sender As Object, e As EventArgs) Handles Button1.Click
    Process.Start("C:\Program Files\Internet Explorer\iexplore.exe", "http://mywebsite.com?refID=" & TextBox1.Text)
End Sub

2) Inside the ASPX page Load Event , you can read Page Request and do your needed actions to it.

If Request("refID") = Nothing Then
   'You didn't pass any values, or TextBox1.text was empty.
Else
   'TextBox1 has some text, do some actions.
End If
