mathematical operations on text boxes

Hello
I have got the following code

Code:

---

CableLos = CableLoss.Text + OTSR_splitterLoss.Text

---

i stick the value 3 in cableloss.text
and 3 in OTSR_splitterloss.text

and i get the value 33 !!

can you guys tell me how to do a sum on these two text boxes.

One of many ways would be to use the Val statement.

VB Code:

CableLos = Val(CableLoss.Text) + Val(OTSR_splitterLoss.Text)

A good thing to remember is that any time that you use math on user input to be sure to convert it to a number. You can use Val() as RobDog suggested or one of the conversion functions.

CByte() - Byte
CInt() - Integer
CLng() - Long
CDbl() - Double
CSng() - Single
CCur() - Currency

thanks dudes
i used the ccur to convert it to currencies

what would the difference between vall and ccur be?

does val return fractional numbers?

Unless it's a date, then use CDate()

Val returns whole numbers. If you did a val on 3.5, it would return 4
