Aborting a dialog from within the dialog

Question

There are 2 Forms FA and FB.
FA is the initial form and it issues FB.ShowDialog() to launch FB. FB starts well, but then encounters a problem and wishes to abort, returning control to FA.
I thought coding

Me.DialogResult = DialogResult.Cancel
Me.Close()

when FB hits the problem would do the trick. but no - the code rumbles on, and (presumably a logic error on my part) bumps into the same problem again, and again.
I will nail the logic problem, but is there no way of actually stopping the form dead - the equivalent of Me.AbortFormImmediately ?

Answer 1

Both the Comments are great and should help the person asking the question
I am going to expand on this question with the thought that Closing forms happens two ways
Either a BACK button is pressed to go to another form
OR
The TitleBar Close Button (the X) is selected
Because I got tired of writing the code on each form to manage these process
I added a Module to the project and added a Public Sub to do all the work

With a little work this Module Code could be improved upon

Here is the Relevant Code

The Module

Module ModuleOne
Public Sub CloseTheForm()
    Const message As String = "YES Go To Form One" + vbCrLf + vbNewLine + "NO CANCEL"
    Const caption As String = "EXIT"

    Dim result = MessageBox.Show(message, caption, MessageBoxButtons.YesNo, MessageBoxIcon.Question)
    If result = DialogResult.Yes Then
        If frmThree.Visible Then
            frmThree.Hide()
            frmOne.Show()
        End If
        If frmFour.Visible Then
            frmFour.Hide()
            frmOne.Show()
        End If

    ElseIf result = DialogResult.No Then
        If frmThree.Visible Then
            frmThree.tbHaveTwo.Text = "CANCEL"
        End If
        If frmFour.Visible Then
            frmFour.tbFive.Text = "CANCEL"
        End If
    End If
End Sub End Module

Relevant Code for frmThree

    Private Sub btnBack_Click(sender As Object, e As EventArgs) Handles btnBack.Click
    tbHaveOne.Clear()
    CloseTheForm()
End Sub

Public Sub frmThree_FormClosing(sender As Object, e As FormClosingEventArgs) Handles Me.Closing
    CloseTheForm()
    e.Cancel = True
End Sub

Code for frmFour

    Public Sub frmFor_FormClosing(sender As Object, e As FormClosingEventArgs) Handles Me.Closing
    CloseTheForm()
    e.Cancel = True
End Sub

Private Sub btnBack_Click(sender As Object, e As EventArgs) Handles btnBack.Click
    tbFour.Clear()
    CloseTheForm()
End Sub
