Getting average from button values??

[jason1987]

im doing a deal or no deal game, i have managed to get the values to randomly appear and be associated with the buttons with duplicates.

my next stage i have got to get the bankers offer, by getting an average to appear from all the buttons currently showing(once they are clicked i need them to hide, and then not be included in the calculation for the offer).

With regards to getting the text on the button into an integer, how do i do this? and once done that, can i make the calculation only include the buttons currently showing??

I thought would be easiest to attach my recent updated code also.

To access only those buttons which are visible, use something like this;

        For Each ctl As Control In Me.Controls
            If ctl.GetType.ToString.ToLower = "system.windows.forms.button" Then
                If ctl.Visible Then
                    'do stuff
                End If
            End If
        Next

To safely get an integer from button text use;

        Dim i As Integer
        If Integer.TryParse(Button1.Text, i) Then
            'Button text is an integer with value i
        End If

thanks I didnt use that exact code, but it inspired me to get some over code.

I currently have:

 Dim J As Integer
        Dim Total As Double
        Dim VisibleCount As Integer
        Dim BankersOffer As String
        Dim Sym As String

        For J = 0 To btn.Count - 1
            If btn(J).Visible = True Then
                Total = Total + CDbl(btn(J).Text)
                VisibleCount = VisibleCount + 1
            End If
        Next

        BankersOffer = (Total / VisibleCount)
        Sym = ("£")
        Dim Offer As String = String.Concat(Sym, BankersOffer)
        Me.lblArv.Text = CStr(Offer)

    End Sub

which works fine, however the final offer im displaying had many decimal places. i need it not to have any, how do i add a formatting bit? im using visual studio, is it in the properties of the label im displaying on, or is this more coding i need to do?

There's a lot of implicit conversions in there. Assuming that you're on a system that has sterling as the default currency format just do this:

Me.lblArv.Text = (Total / VisibleCount).ToString("c0")

That formats the result of the calculation as a currency string (that's the "c") with no decimal places (that's the "0") and assigns the result to the Text property of the Label.

wow, thankyou very much, looks exactly how i want it now, i was never aware of the currency function. thanks

Thanks very much, that has sorted that issue out.

I now need to make a picture box appear with the same tag as the box that is clicked.

for example I have a button with the tag 0.01 and now picturebox1 with the tag 0.01 also.

How will i code this as it will be a different button each time with the 0.01 tag

I have 22 different tagged buttons and 22 different tagged picture boxs which im using to cover up something on my background when the button with the same tag is clicked

the values:

0.01,0.10,0.50,1,5,10,50,100,250,500,750,1000,3000,5000,10000,15000,20000,35000,50000,75000,100000,2 50000


any help given, many thanks
