Jimcaale · October 3rd, 2010, 02:05 PM

i have a form in my application that calculates the invoice of all the charges of a patients. there is a form that calculates the room charges of the patient but it will no update the previous record.
what i want is the room charges form to calculate and add the room charges of the patient then display the result in listview. if i add a new room charge i want the form to update the total charge in the listview.

thanks

First off why a listview? Why not a label or a textbox?

How many items are in the listview? The items are in a base 0 array so if it's just one item it's index will be 0.

Here is a simple example. (In this sample i use the Button1.Click event. you would obviously use an event that trigers when the calculations are made.)

Code:

    Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
        ListView1.Items.Add("hello")
    End Sub

    Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
        ListView1.Items.Item(0).Text = "good bye"
    End Sub

Finally what does this have to do with Visual Basic .NET list view is a COM control.
