Hi Mohannad S,

Welcome to ASP.NET forums.

How I can gets value from external URL to display on the home page inside
TextBox?

If you'd like to consume an external service to get the data and display the returned data in a TextBox from you vb.net webform application, you can refer to the following code snippet:

Dim client As HttpClient = New HttpClient()

Dim Response As HttpResponseMessage = client.GetAsync("http://xxxx/api/getdata").Result

If Response.IsSuccessStatusCode Then
    TextBox1.Text = Response.Content.ReadAsStringAsync().Result
End If

Besides, if you'd like to make request from JavaScript client-side to get the data, you can use jQuery.ajax().

You can use the following code to get the QueryString and display it in your TextBox control.

If Request.QueryString.Get("Mobile") IsNot Nothing Then
    TextBox1.Text = Request.QueryString.Get("Mobile").ToString()
End If

Test Result:

Hi Mohannad S,

My need is: get the phone number from this windows service and put this number in textbox in my asp home page.

It seems that you'd like to get the phone number from your windows service and push the phone number to an existing web page that you opened before. If so, you can try to use ASP.NET SignalR to implement this functionality.

1) map browser client to connectionid

2) add queue message after the windows service get a phone number, and specify which client (via connectionid) should receive this number

3) use a queue triggered job to handle queue message, and call hub server method to push the phone number to specific client

4) in web application client side, dynamically assign phone number as value of TextBox control once the client received the pushed message
