Here's a useful little tip for if you have a numeric value and you need to convert it into your local currency.
Let's assume you take in a value as a Double and you want the output to be in the format of currency, with two decimal places (in the case of the UK to represent Pence).
Here's the Double:
Dim TotalCost As Double = 123.4567
To show this formatted, you can use the String.Format method, a placeholder for the variable and the 'c' attribute to ensure the currency format is used:
Label1.Text = String.Format("Total Cost = {0:c}", TotalCost)
The result would look like this:
Notice that it automatically rounds up for you, changing '4567' to '46'.
