I'm trying to read and save a text file from an URL (api.ivao.aero/getdata/whazzup/whazzup.txt) with Visual Basic but I couldn't find the syntax to download it. It even will be enough if I can read this text and write it to a TextBox. (Visual Studio 2015)
Yes it can be done.
Import these :
Imports System.IO
Imports System.Text
Imports System.Net
Then try this:
Dim address As String = "http://api.ivao.aero/getdata/whazzup/whazzup.txt"
Dim client As WebClient = New WebClient()
Dim reader As StreamReader = New StreamReader(client.OpenRead(address))
Textbox2.Text = reader.ReadToEnd
The text from the url will be displayed/read in textbox2. To have better idea/knowledge about using StreamReader to Read Text from Files, you may read this article. Hope it helps.
