Calculate sum of currency textbox values

Hi Experts,

I need help on what is probably a very basic question for someone that knows what they are doing.

Windows Application, VB.net 2005, SQL Server 2005.

TextBoxA = Currency value
TextBoxB = Currency value
TextBoxC = Currency Value
TextBoxD = Currency Value
(Values can be Null)

TextBoxE = Sum of the values above

Thanks in advance for your help.

Dave

Hi

The following code does exactly what you explained (according to how I understood it):

        Dim a(4) As Decimal
        Dim Result As Decimal
        a(0) = System.Convert.ToDecimal(Val(TextBoxA.Text))
        a(1) = System.Convert.ToDecimal(Val(TextBoxB.Text))
        a(2) = System.Convert.ToDecimal(Val(TextBoxC.Text))
        a(3) = System.Convert.ToDecimal(Val(TextBoxD.Text))

        Result = a(0) + a(1) + a(2) + a(3)
        TextBoxE.Text = Result.ToString

Hi,

Thanks for the response.
I used the code on a buttonClick event...
Tried the from load...
 
I can't get the code to work, maybe I wasn't clear on my post.

Using the ButtonClick event, TextBoxes A,B,C,&D show their individual values in TextBoxE but the sum of the TextBoxes are not calculated.

HI,

Let's try this:

All TextBox Null values are $0.00
Properties are set to Currency.

I enter these amounts:
TextBoxA = $10.00
TextBoxB = $10.00
TextBoxC = $10.00
TextBoxD = $0.00

After buttonClick event:
TextBoxE changes from $0.00 to 0 (Should be = $30.00)

I hope this helps.
