My.Computer.FileSystem
New with .net 2.0
Reading from a file:
label1.Text = My.Computer.FileSystem.ReadAllText("Myfile.txt")
Saving a file
My.Computer.FileSystem.WriteAllText(“Myfile.txt”,textbox1.text, true)
Without a path it saves the file in the same directory are the application.
In this case the bin/debug folder of my project
Stream from a network
- Streams can be more than files
- Create a new project
- Add a button and a textbox
- Set the textbox to multiline and the scrollbars to Both
- Add this code to the top of the page:
Imports System.IO
Imports system.net
- Add this code to the button click event:
Dim myRequest As WebRequest
myRequest = WebRequest.Create("http://www.starkstate.edu")
Dim theResponse As WebResponse = myRequest.GetResponse()
Dim responseStream As Stream = theResponse.GetResponseStream()
Dim reader As New StreamReader(responseStream)
The Stringbuilder class provides a more efficient way to concatenate strings. Adding one string to another actually causes a new string to be created.
Add this code to the top of the page:
Imports System.Text
Add this code below your previous code in the button click event:
Dim sb As New StringBuilder
Do
sb.Append(reader.ReadLine)
sb.Append(vbCrLf)
Loop While Not reader.ReadLine Is Nothing
TextBox2.Text = sb.ToString()
