RE: spremanje u txt ili u nes drugo

Moras prvo smisliti na koji nacin da zapisujes u fajl s tim da pazis da je taj fajl sto lakse ponovo ucitati ja predlazem ovako:

Primjer sadrzaja fajla:

Code:

Coca-Cola;2;3

Cedevita;1.5;5

Znaci:

Code:

naziv_artikla;cijena;kolicina

Tvoj program bi trebao citati liniju po liniju, razbijati stringove pomocu split metode (potrazi na internetu kako). Fajlove citas pomocu IO.StreamReader objekta, a pises pomocu IO.StreamWriter.

RE: spremanje u txt ili u nes drugo

ev napravio sam nes pa cu sad pokazat kako to izgleda :)

ovo sto sam ovdje napravio primjenit cu i u ovom gore primjeru

slika 1
dakle opcija open

Code:

Dim open As New OpenFileDialog

        Dim mystreamreader As System.IO.StreamReader

        open.Filter = "text [*.text*] |*text|All Files [*.*]|*.*"

        open.CheckFileExists = True

        open.Title = "Open File"

        open.ShowDialog(Me)

        Try

            open.OpenFile()

            mystreamreader = System.IO.File.OpenText(open.FileName)

            document.Text = mystreamreader.ReadToEnd

        Catch ex As Exception

onda opcija save

Code:

Dim save As New SaveFileDialog

        Dim mystreamwriter As System.IO.StreamWriter

        save.Filter = "text (*.text)|*.txt| All Files (*.*)|*.*"

        save.CheckPathExists = True

        save.Title = "Save File"

        save.ShowDialog(Me)

        Try

            mystreamwriter = System.IO.File.AppendText(save.FileName)

            mystreamwriter.Write(document.Text)

            mystreamwriter.Flush()

        Catch ex As Exception

onda save as

Code:

Dim saveas As New SaveFileDialog

        Dim mystreamwriter As System.IO.StreamWriter

        saveas.Filter = "text (*.text)|*.txt| All Files (*.*)|*.*"

        saveas.CheckPathExists = True

        saveas.Title = "Save File"

        saveas.ShowDialog(Me)

        Try

            mystreamwriter = System.IO.File.AppendText(saveas.FileName)

            mystreamwriter.Write(document.Text)

            mystreamwriter.Flush()

        Catch ex As Exception

onda undo

Code:

document.Undo()

redo:
