Question Save File Dialogue

[david84]

This save file dialogue works fine except when they click save, the dialogue opens and then they close the dialogue. when they close it, my program crashes, every time. i'm using this to save it

Dim sfd As New SaveFileDialog
        With sfd
            .Filter = "Text Documents (*.txt)|*.txt|PHP (*php.*)|*php.*"
            .FilterIndex = 1
            .Title = "Save File As"
        End With
        sfd.ShowDialog()
        IO.File.WriteAllText(sfd.FileName, Textbox.Text

That's probably because you're not checking for Cancel or anything before writing the text out

If sfd.ShowDialog() <> DialogResult.Cancel Then ... write the text

You are probably right, but just to be sure....

What is the error message you get when it "crashes"?

Ok thanks. this worked. could you please explain the use of "<>" though?

It's the opposite of "=", it means "Equals Not". In c/c++/Java/c# the "equals not" is "!=" and "<>" is vb's syntax for it. vb can also have "Not Something = SomethingElse" to achieve the same result.

I had a feeling it may be. Thanks a lot.
