Replace your Exit For with Return when you find a "bad value".
After the For ... Next loop, open the new form:

Dim mnf As MyNewForm = New MyNewForm()
mnf.ShowDialog()

Or

Dim mnf As MyNewForm = New MyNewForm()
mnf.Show()

depending on what you need it to do.

BTW: It's a much better idea to check TextBoxes for Double values using TryParse:

Dim d As Double

If Not Double.TryParse(myTextBox.Text, d) Then
    MessageBox.Show("""{0}"" is not a valid number.", myTextBox.Text)
    Return
End If

Solution 2

I think you should remove the Exit For.
To call another Form:

If EmptyTextBoxFound = False Then
    Dim form2 As New Form2()
    form2.Show()
End If

This is a problem, because if all is ok then my code end on first if - If v1 > max_x OrElse v1 < min_x Then

Not when you remove the Exit For !
