Hi there,

I have three text boxes on the form. First is for the total amount (that is the total due amount for the client), enter by the user. Second text box is for to enter the value (payment) which user pays. In the third text box i want the calculate value (i.e total value - current value entered) on the Lost Focus event of second text box.

Plz guide me in this.

Put this in your LostFocus event for text box 2:

Text3Name.Text = cint(Text1Name.Text)-cint(Text2Name.Text)

Replace the "TextName" with the names of your text boxes. Also, you will probably want to do validation to make sure they are numbers.
