Using variable in button to give value to label

[violet469]

I have tried this on a MacBook with Parallels running Windows 7, and on a Vaio desktop running Windows 7, but both with Visual Studio 2012:

I am trying to use different buttons to assign different values to a variable.
There are 2 variables using different buttons to assign them.
These variables are being added together to assign value to a label.

I believe my error is in my syntax but I have not found out how to use a button to set the value for a variable.

I get no error codes, I just do not get a result in my final label. It stays blank.


Here is a chunk of my code:

Public Class frmLunchCombos

‘I went ahead and defined my variables
    Dim dblSandwichCost As Double
    Dim dblSoupCost As Double


'Click TomatoBasil
    Private Sub btnTomatoBasil_Click(sender As Object, e As EventArgs) Handles btnTomatoBasil.Click

‘I mean for this to set SoupCost to the value 2.49        
dblSoupCost = 2.49

     End Sub


'Click ClassicTurkeyBreast
    Private Sub btnClassicTurkeyBreast_Click(sender As Object, e As EventArgs) Handles btnClassicTurkeyBreast.Click

‘I mean for this to set SandwichCost to the value 3.49

        dblSandwichCost = 3.49

    End Sub



Private Sub lblCalcSubtotal_Click(sender As Object, e As EventArgs) Handles lblCalcSubtotal.Click

      ‘I made dblValue for easy formatting of the final label

        Dim dblValue As Double

 ‘Value= SoupCost (which would be assigned to 2.49 after clicking Tomato Basil) + SandwichCost (which would be assigned to 3.49 after clicking ClassicTurkeyBreast)

        dblValue = dblSoupCost + dblSandwichCost

 ‘And then convert Value to a currency-formatted string

        lblCalcSubtotal.Text = dblValue.ToString("C")

    End Sub

Many thanks in advance! I really want to understand this and I feel like it's something simple.

Dear Friend,
Your problem invoked a hornets nest in my programming world.I was doing C-Pad programming(cmd & notepad)
and suddenly i found your problem has creeped in to my C-Pad also.No textbox,listbox or label is responding
to button click.It was working easily for me all these days.Microsoft uploaded many updates recently(just 3 days since)
They must have screwed up something.Anywa y,i did your project in visual studio express 2013 and uploaded to
the URL:-(given below)

I used a listbox instead of label.No problem.Even Label and Textbox will work fine.Now i will have to analyse what went
wrong in my C-Pad style.I have uploaded many projects to the following URL:-(It includes VB.Net and WPF-with-VB.Net).

Do
try out those and tell me whether they work in your Computer.I have windows 8.1.

Dear Friend,
I worked further and made your project as per your expectations.I also found out that It is not Microsoft who screwed up,But it is me.
I actually had a simple error which i overlooked.Anyw ay it helps me to blame Microsoft first and then on retrying locate the blame on myself.
(Not surprising considering my age-68+)This project is named Project469 and uploaded to URL:-(It is in C-Pad style)

You have to call the compiler from your cmd window as given below.First place the two .vb files(Violet2.v b and Violet22.vb) in a folder
-New folder(you can name it appropriately).
The compiler calling is:-

path=%path%;c:\ windows\microso ft.net\framewor k\v4.0.30319
VBC /OUT:Violet2 /T:winexe C:\Users\...... .\Desktop\Folde r\Violet2.vb
VBC /OUT:Violet2 /T:winexe C:\Users\...... .\Desktop\Folde r\Violet22.vb C:\Users\VEKATR AMAN\Desktop\Ne w folder\Violet2. vb
Violet2

NOTE:The dotted portion is particular to your computer.Mostly it will be your name.Change the New folder to whatever you want.
This project is exactly what you wanted-with ListBox as a bonus addition.
