Visual Basic 2010 Express access files during run?

Question

I am trying to make a program for one of my teachers, he asked me to make a program where, while you run it, you can click on a box and it opens up a window that allows you to select a file from your computer and save it in the box. It would be nice, though not necessary, to also have it so that when the program closes, it saves what pictures are there. If someone could give me a step-by-step walkthrough for this I would appreciate it.

Sure sounds more like a homework assignment to me.  Regardless: http://msdn.microsoft.com/en-us/library/dd492135(VS.100).aspx  There.  Picture viewer walk through.  If it is homework I don't advise you doing it this way, you'll probably get caught.

I have done this before but i don't have the code on me so im going to be helping you from my brain. so some of this might not work right away and you are probably going to have to tweak the code.  Also i was programming in C#.Net not VB. 

First you want to look for a menu strip. In the Tools.  listed under Menus & Toolbars. Next you want to add Open file dialog and save file dialog. You can find both of thouse in the Dialogs inside the toolstip. 

This is for the Open File. 

        Dim SpaceHoldingReader As String = ""

        OpenFileDialog1.Title = "Open File"
        OpenFileDialog1.Filter = "txt Files (*.txt)|*.txt|All Files (*.*)|*.*"
        OpenFileDialog1.FileName = ""
        OpenFileDialog1.InitialDirectory = "MyDocuments"
        OpenFileDialog1.ShowDialog()
        SpaceHoldingReader = OpenFileDialog1.FileName
        Dim sr As New StreamReader(SpaceHoldingReader, True)
        RichTextBox1.Text = sr.ReadToEnd

        sr.Dispose()
        sr.Close()


This is for the save

  Dim Savefile As String = ""

        SaveFileDialog1.OverwritePrompt = True
        SaveFileDialog1.FileName = Savefile
        SaveFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*"
        SaveFileDialog1.ShowDialog()

        If SaveFileDialog1.FileName.Length = 0 Then
            MsgBox("Canceled")
        Else
            Dim sw As New StreamWriter(SaveFileDialog1.FileName, True)
            sw.Write(RichTextBox1.Text, True)
            sw.Dispose()
            sw.Close()
        End If


To use images ill let you figer it out. Dont worry ill give you a good hint. 

use Image Files(*.BMP;*.JPG;*.GIF)|*.BMP;*.JPG;*.GIF|All files (*.*)|*.*  where  the code says OpenFileDialog.filter = "txt Files (*.txt)|*.txt|All Files (*.*)|*.*" and add it to the code that is there so that it accepts thoughs types of files as well. 

Its not tuff i think you can do it. 

Good luck and try it out, it only takes a tiny amount of thought to make it work.
