VB 2010 Express saving and opening text file

Hey i have a few fields setup as a form example:
UsernameTextbox.Text
EmailTextbox.Text
CountryComboBox.Text
------
I have a save button on the form screen called Button1.
When this button is pressed, i want the user to be able to save the above data to a file anywhere they want on their harddrive and name it whatever they want.

-------
I also have another button on the screen called Button2.
When this button is pressed, i want the user to be able to load data which was saved before.

If possible the file extension should change to something like .nme rather than .txt this will help error handling as users should only be able to load/save files with that extension.

I really don't understand any of that, how would i use it
        Dim myStream As Stream
        Dim saveFileDialog1 As New SaveFileDialog()

        saveFileDialog1.Filter = "net manager e (*.nme)|*.nme"
        saveFileDialog1.FilterIndex = 2
        saveFileDialog1.RestoreDirectory = True

        If saveFileDialog1.ShowDialog() = DialogResult.OK Then
            myStream = saveFileDialog1.OpenFile()
            If (myStream IsNot Nothing) Then
                ' Code to write the stream goes here.
            End If
        End If

Open in new window


When i click the button it loads up with the save dialog, with a single extension as i set it, how do i write my values into this file?

On another note, i have another label called done1. this labels value is default set to NO this should also be stored on the text/nme file in my case.

But i have another command button called command2 on another form, when clicked it should update the value of done1 to YES, this should update the form aswell as the text/nme file which the user has saved before when first creating the file.

SaveFileDialog is the component that would give you this functionality. It displays a dialog box to the user which allows him to navigate his filesystem and select a location and filename to save a file as. There is a member called Filename which you would pass to some Stream object in order to write the data to be saved to a file.

OpenFileDialog is the component that would give you this functionality. It displays a dialog box to the user which allows him to navigate his filesystem and select a file to open. There is a member called Filename which is what you would pass to some Stream object in order to actually get the data from the file.

Thank you so much i was looking for this all of this time  EmailTextbox.Text = sr.ReadLine() :),
it should help me with this .
"But i have another command button called command2 on another form, when clicked it should update the value of done1 to YES, this should update the form aswell as the text/nme file which the user has saved before when first creating the file."

all i will do is write to a text file,then load a text file, at the time of loading i will get the path to the file, so when it comes to writing the values for done1 that path can be used :) thank you
