Hey guys Just learning about List Boxes, I have a quick Question Im Creating the Program where I have 3 text boxes and when I hit the add button it adds them to the list box off to the right if they already Exist in the list box then it will bring up a message box saying that it already exists.
I have another button labled Replace button and its suppose to update or replace the string or line if changes are needed to be updated or replaced. How can I creat it to Replace or update the Data in the String or Line?
Here is my Code:
Public Class Form1
Dim ID As Integer
Dim AName As String
Dim ABalance As Double
Private Sub AddButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles AddButton.Click
ID = AccountIDTextBox.Text
AName = AccountNameTextBox.Text
ABalance = BalanceTextBox.Text
If AccountsListBox.Items.Contains(ID & ", " & AName & ", $" & ABalance) = True Then
'Checks to see if the line or String Exists
MessageBox.Show("That Account already Exists!")
'If it does Exist or is already created
Else
AccountsListBox.Items.Add(ID & ", " & AName & ", $" & ABalance)
'If it it dosent exist it inserts or adds the line to the listbox
End If
End Sub
Private Sub ReplaceButton_Click(sender As System.Object, e As System.EventArgs) Handles ReplaceButton.Click
If AccountsListBox.Items.Contains(ID & ", " & AName & ", $" & ABalance) = True Then
'If the Line Does Exist replace or update the String or line
Else
MessageBox.Show("You cant replace that account because the Account dosent Exist!")
'If line does not Exist does not update or add
End If
End Sub
End Class
