Hi,

Sorry if this seems a bit of a stupid question, I'v not used Visual basic in a long time.

But can somebody help me out, I need to open a text file from the internet into a textbox, however I dont want to download the file, Only open it, Can someone help

Thanks

All things taken from the internet is downloaded first, but the thing you probably want to use is a Net.Webclient and using its DownloadString function. :)

Okay,
But I was thinking more like how it is opened when opening files from your filesystem.

like my.computer.filesystem.filexists("C:\example.txt") and so on.

this:

my.computer.filesystem.filexists("C:\example.txt")

won't open a file, so I don't really get what you mean.
The thing I said before will give you a string containing the source of the page-

Okay, Basically I want to do how you open a picture from the internet like this

picture1.picturelocation = ("http://randomsite.com/randomimage.jpg")

but for a text file, something like this

textbox1.filelocation = ("Http://randomsite.com/randomtext.txt

i think use a textreader
TextReader Class (System.IO)

read the text from the URL , then cast that to a string , then assign it like this

TextBox1.Text = (string) Textreadfrom URL;

For the textbox thing you can just do the thing with the webclient and downloadstring as I said before.
For the image thingy you can use the downloaddata function to get a byte array and then convert it to an image, I found how to do it here(Windows Developer Blog: Convert image to byte array and vice versa) and I've tested it and it works like a charm.

Vswe,

I do not want to download the files, I simply want to access the data without downloading it.

Any way of doing that?

To access data from the internet, on your computer... it HAS to be downloaded. Even webpages, when you view them are technically downloaded, even be it temporarily. So in theory, you need to download the text file, then open and read it.

That's just how it works. But for how your program actually works, you wont tell the difference.
