ListView Tally Dollars

I would like to automate this so it will calculate once the list is generated. I don't want the user to have to click on anything, I found this but can't seem to tweak it to be automatic.

Dim indexes As ListView.SelectedIndexCollection = _
        Me.ListView1.SelectedIndices
    Dim index As Integer
    Dim price As Double = 0.0
    For Each index In indexes
        price += Double.Parse(Me.ListView1.Items(index).SubItems(1).Text)
    Next

    ' Output the price to TextBox1.
    TextBox1.Text = CType(price, String)

Open in new window

Would help if I put the code with this :) - need more coffee
' NO TIMER
Private sub ListView_ItemClick()
    Dim indexes As ListView.SelectedIndexCollection = Me.ListView1.SelectedIndices
    Dim index As Integer
    Dim price As Double = 0.0
    For Each index In indexes
        price += Double.Parse(Me.ListView1.Items(index).SubItems(1).Text)
    Next

    ' Output the price to TextBox1.
    TextBox1.Text = CType(price, String)

End Sub

' WITH TIMER
' set timer INTERVAL property to something you can tolerate where 1000 = 1 second
Private Sub tmrCalcME_Timer()
    
    Dim indexes As ListView.SelectedIndexCollection = Me.ListView1.SelectedIndices
    Dim index As Integer
    Dim price As Double = 0.0
    For Each index In indexes
        price += Double.Parse(Me.ListView1.Items(index).SubItems(1).Text)
    Next

    ' Output the price to TextBox1.
    TextBox1.Text = CType(price, String)
End Sub

You could put a timer on your form that will fire when anything in the listview index changes.
Perhaps in a click event or in your item click or itemcheck events.

put about 100 on the timer, disable it when it starts and run your code above in the timer.

The more I look at the solution I gave the more I realize I had not  had coffee when I typed it.
A timer would be useless (unless) it ran on it's own and ran constantly which could cause a drain on you.

If you could put the above code in an event of your listview that fired when a value changed then you would be fine.  Otherwise - if there are no events that would help you like the ones I mentioned then a timer may work instead.

For some reason it just don't generate anything into the textbox, I have the correct sub and listview entered. Just weird, is it possible to just open a file read it all and then calculate the values from it, that would be easier for me lol.

Perhaps the event is not working - did you try the timer method ?
make sure the timer is enabled and an interval entered

well got my cup of joe kicked in, got it to load the timer but only gives a value of 0 as a result, the subitem should be 4 according to the colums that I set in ListView2 box.

So did some tweaking and got it to generate a dollar amount, however I don't want the user to have to click anything to generate the info, is there a small code I can put to tell vb to auto select the first row of data?


The following code works to generate the info, but wanted it to be automated so user don't have to click.
 Dim indexes As ListView.SelectedIndexCollection = Me.ListView2.SelectedIndices
        Dim index As Integer
        Dim price As Double = 0.0
        For Each index In indexes
            price += Double.Parse(Me.ListView2.Items(index:=4).Text)
        Next

        ' Output the price to TextBox1.
        vehrtlprice.Text = CType(price, String)

Have you tried the timer ?

Jack_JonesAuthor Commented:
Yep the timer works, but only when you click an item in the ListView2 control, just want it to auto generate without the user having to click on the listview item.

Finally got it figured out, will give you props for the timer idea that I didn't even thing of.

ListView2.Items(0).Selected = True
        ListView2.Select()
