I'm new to vb6.0. And i am having a hard time trying to learn the variables and stuff. I have to code the square root button so it calculates and displays the square root of a whole number. I have to assign the numeric equivalent of the txtNumber.text property to an integer variable. And i have to assign the square root to a single variable. Can you help please?

If the integer variable was called 'i' then you could probably use this code:
| i = Sqr(txtNumber.Text) |
You would have to make sure that the txtNumber.Text had a valid number or you could error handling in the procedure.

What you have Martin is good but it brings possible erros - try this
Dim i as
integer
Dim IsNumber as boolean
IsNumber = isNumeric(txtNumber.text)
if IsNumber = false then
i = msgbox("Please enter a number into the
textbox!",vbokonly,"Number Error")
exit sub
end if
i = txtNumber.text
i = Sqr(i)
lblAnswer.caption = i
'This code is better because is prevents the error by
finding it and telling the user

You are right Chris, but I did suggest this.
