[RESOLVED] Upload from database! Help!

[Quazaka]

My friend and I are making a program, and we need some help. We need the option to make the program get info from a place that we always can update, so. This is what we want.

We got a program there got a button, called "Get Info". When it is pressed the program recive some info from a place that we can update whenever we want.

Like a database, where people can be updated with data from.

Like this: in the datebase there is typed "I" and "Like" but, after some time we also want to add "cake" but whitout the person using ouer program, have to download the version 2.

Any help will be appreciated. Thank you for spending your time helping us!

Ok, so like I don't know but like you used like to much in your comment.

What I get is that if you retrieve something with the word "cake" (The cake is a lie you know), the program decides to update itself.

You've got the basics down, but you forget a few things:
1. Where can it download the update
2. If its updated, and it reads cake, its going to want to update again, problem!
3. Where's the database stored

Solve/Answer those three problems/questions and you should be good to go.

1. Where can it download the update
2. If its updated, and it reads cake, its going to want to update again, problem!
3. Where's the database stored

1. We don't know how to make this, we dont know anything. right now evrything is beta.
2. why does i wants to update again? the program got a buttom called Get, and when its press a random value from ouer datebase will be showen in a textbox. ?
3. we don't got one.

Presumably you want to update all users?

Are all users on the same physical network, or will you be relying on the internet to retrieve the update?

[Quazaka]

Yes we want to update all the users with new info, if they click the button called "get".

All users are not on the same physical network, therefore we need to rely on the internet.

OK so you need some form of web hosting to store the a file containing the updates, then you can use an httpwebrequest to download it.

You can see an example of downloading a file in this way here.

Okay thank you for the help! I will try it out.

Okay we tried it out and edited a bit in the code.

Imports System.IO
Imports System.Net
Imports System.Text
Class WebRetrieve
    Public Shared Sub Main()
        Dim wr As HttpWebRequest = CType(HttpWebRequest.Create("http:/xxxxx.com/xxx.txt"), HttpWebRequest)
        Dim ws As HttpWebResponse = CType(wr.GetResponse(), HttpWebResponse)
        Dim str As Stream = ws.GetResponseStream()
        Dim inBuf(100000) As Byte
        Dim bytesToRead As Integer = CInt(inBuf.Length)
        Dim bytesRead As Integer = 0
        While bytesToRead > 0
            Dim n As Integer = str.Read(inBuf, bytesRead, bytesToRead)
            If n = 0 Then
                Exit While
            End If
            bytesRead += n
            bytesToRead -= n
        End While
        str.Close()

        Dim fileContent As String = System.Text.ASCIIEncoding.ASCII.GetString(inBuf)
        Dim sReader As New StringReader(fileContent)

        While sReader.Peek() <> -1
            Dim line As String = sReader.ReadLine()
            Dim linecontent() As String = line.Split(CChar(" "))
            Debug.WriteLine(String.Format("Username is {0} and status is {1}", linecontent(0), linecontent(1))
        End While
    End Sub 'Main
End Class 'WebRetrieve

We got that part of the code. The problem is now that we do not know how to read the code that we just got. We would like to read the txt file when we click a button called "get". But! we need to get a random line and add it to txtbox1, which is the user, and txtbox2, which is the status.


xxx.txt:

user1 status1
user2 status2
user3 status3
etc...

So the program needs to read a random line and add it to two textboxes.

Any help will be appriciated
