Vaildate Currency

Hi,

Sorry for this noob question.

Can I know how can vaildate if the user enter a vaild currency value?

Do I have to vaildate the same way as I vaildate numbers such as check for negative vaule, string etc?

Can I set Minimum or Maximum value or Can i use the textbox property under "Max Length".

Can I set a code that allow the program to accept $0.00 but not 0?

How can I differentiate between the two?

use masked edit control or add a code that validate event of the textbox
