[2008] Download text from internet

Hey, I'm trying to get a line of text from a webpage, and put it in a label. Just some experimenting stuff. I have this to download an image:

Code:

---

PictureBox1.Image = New System.Drawing.Bitmap(New IO.MemoryStream(New System.Net.WebClient().DownloadData(TextBox1.Text)))

---

Just wondering if theres anything I can do from that for this :D

Thanks in advance

To download the text from a document on the internet, use the WebClients DownloadString method.

VB.NET Code:

Dim text As String
        Using client As New System.Net.WebClient
            text = client.DownloadString("http://....")
        End Using

Then you'd have to parse out the part(s) you need from the downloaded string.

Thanks, but it just gives me the script of the website, is there any way that I can get the text from the site?

nevermind, realised that it can read from text files, which is great :D will rate you
while I'm here, is there any way that I can type into the .txt file that's in my ftp? (keep in mind I'm pretty nooby at VB and internet stuff)

You can not directly modify a file on an FTP server. As the name File Transfer Protocol implies, you can only transfer files from and to the server. You will have to download the text file, modify it, and send it back to the server.

and can I do all that in my app?

Sure, take a look at the System.Net.FtpWebRequest class.

looked at it, and have no idea what to do... sort of got a little bit into the create, but I hav no idea how to put in a password, has it got something to do with

Code:

---

New System.Net.NetworkCredential

Ah I seem to have confused myself there for a moment. You can use the WebClient to download/upload files from/to FTP servers

VB.NET Code:

Dim byteData() As Byte
        Using client As New Net.WebClient
            client.Credentials = New System.Net.NetworkCredential("user", "password")
            byteData = client.DownloadData("ftp://....")
            ' Do whatever you want to the byteData array; write it to a file or modify it directly.
        End Using

Uploading is done in a similar fashion.

ok, I have no idea how I'm supposed to do the uploading, so could u get me started?

MSDN again to the rescue. http://msdn2.microsoft.com/en-us/library/tdbbwh0a.aspx

If you're using the WebClient.DownloadFile or DownloadData method to download files or data, what do you suppose you might use to upload files or data?

lol, webclient.uploadfile seemed like a good idea, till the dreaded blue zigzag appears...

Care to share your code?

No errors here:

vb.net Code:

Public Class Form1
    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        Dim wc As New Net.WebClient
        wc.UploadFile("ftp://somewhere.com", "somefile.txt")
    End Sub
End Class

As nmadd suggests, it serves neither us nor you to tell us that you get errors if you don't show us what you're doing and tell us what error messages you get. Ringing the mechanic and telling him that your car won't go doesn't get it fixed.

using nmadd's code I got this error:
An exception occurred during a WebClient request.
Could it have something to do with the ftp I'm trying to access?

any help would be great :D

We already know that an error occurred during the WebClient request. You've still told us nothing. You need to provide us with all the information that the IDE has provided you with. That's why the IDE provides the information: to help diagnose the issue. You have to show us the exact code that you're executing and you have to show us all the details of the exception. Have you actually clicked the View Details link on the Unhandled Exception dialogue? Have you considered actually catching the exception and interrogating it yourself?
