VB Calculation code

[mel1]

Hello I am new to VB and am teaching myself. I am wanting to perform a simple calculation. Two text boxes (one for a price and the other for a quantity) which will subsequently display a total price in a third text box. Two activate the total I will press a button called calculate. Can anyone help with this as I have a tried a few codes and am getting a coding error. I am using a dim statement for my variables: Dim price, qty, total As Double (is double the correct data type to use?) Please help Thank you

Show your code.

Code as below:

Private Sub Command10_Click()
Dim price, qty, total As Double
Item_Price.Text = price
Quantity.Text = qty
Text11.Text = total
Text11.Text = Format(price * qty, "0.0")

Try this

Private Sub cmdcalculate_Click()
    Dim price As Double
    Dim qty As Integer
    Dim total As Double
    price = Val(Text1.Text)
    qty = Val(Text2.Text)
    Text3.Text = Format((price * qty), "000.00")
End Sub

Dim price, qty, total As Double

This Dims total as Double, but price and qty as Variants. You have to specify the type for each variable

Dim price As Double, qty As Double, total As Double

Private Sub Command10_Click()
Dim price, qty, total As Double
    [B]Item_Price.Text = price[/B]
    [B]Quantity.Text = qty[/B]
    Text11.Text = total
    Text11.Text = Format(price * qty, "0.0")
End Sub

= moves the value from right to left.

You are putting the values of the variables into the textboxes.
For your calculation you need to do it the other way around.
