Have a look at the SaveFileDialog and OpenFileDialog components:

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

Select allOpen 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.

>>  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.

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.

 

I have already Done that?

"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
