Hi Roland,

To round, you use static method System.Math.Round(nNumber, nDigits)

dTotal = System.Math.Round(dPrice * dTaxRate,2)

To work with Textboxes, you need to use the Text property of the Textbox to extract the value entered in the control

dTotal = CDec(cbPrice.Text) * dTaxRate

>Can you set a textbox to a datatype?

Textbox.Text property must always be set to a string. You need to convert it to other data types when you extract it's value.

>Can you set a format to decimal with length 10 with 2 decimals?

To format textboxes, you need to use the techniques shown in message #670154
