VB.NET editing existing that with a form
- by user127147
Hi there,
I have a simple questions that puzzles me. I need a little bit of refreashment with VB as I have been away for a while. I have a form that adds new contacts. New contacts are added by pressing an appropriate button and they appear as an entry in the list on the form. I try now to add an edit button that will edit existing entries. User will select a given entry on the list and press edit button and will be presented with an appropriate form (AddContFrm). Right now it simply adds another entry with the same title. Logic is handled in a class called Contact.vb Here is my code.
Public Class Contact
Public Contact As String
Public Title As String
Public Fname As String
Public Surname As String
Public Address As String
Private myCont As String
Public Property Cont()
Get
Return myCont
End Get
Set(ByVal value)
myCont = Value
End Set
End Property
Public Overrides Function ToString() As String
Return Me.Cont
End Function
Sub NewContact()
FName = frmAddCont.txtFName.ToString
frmStart.lstContact.Items.Add(FName)
frmAddCont.Hide()
End Sub
Public Sub Display()
Dim C As New Contact
'C.Cont = InputBox("Enter a title for this contact.")
C.Cont = frmAddCont.txtTitle.Text
C.Fname = frmAddCont.txtFName.Text
C.Surname = frmAddCont.txtSName.Text
C.Address = frmAddCont.txtAddress.Text
'frmStart.lstContact.Items.Add(C.Cont.ToString)
frmStart.lstContact.Items.Add(C)
End Sub
End Class
AddContFrm
Public Class frmAddCont
Public Class ControlObject
Dim Title As String
Dim FName As String
Dim SName As String
Dim Address As String
Dim TelephoneNumber As Integer
Dim emailAddress As String
Dim Website As String
Dim Photograph As String
End Class
Private Sub btnConfirmAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnConfirmAdd.Click
Dim C As New Contact
C.Display()
Me.Hide()
End Sub
Private Sub frmAddCont_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub
End Class
and frmStart.vb
Public Class frmStart
Private Sub btnAdd_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAdd.Click
frmAddCont.Show()
End Sub
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDel.Click
Dim DelCont As Contact
DelCont = Me.lstContact.SelectedItem()
lstContact.Items.Remove(DelCont)
End Sub
Private Sub lstContact_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles lstContact.SelectedIndexChanged
End Sub
Private Sub btnEdit_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnEdit.Click
Dim C As Contact
If lstContact.SelectedItem IsNot Nothing Then
C = DirectCast(lstContact.SelectedItem, Contact)
C.Display()
End If
End Sub
End Class
