Quote:I need an equation such as a * b = c and a / c = b and b / c = a where the user types in 2 of the variables in text boxes and some proccess (such as a button click) would calculate the result.
first, I know what you mean by circular reference but in the way excel means it is that a circular reference is a feedback loop... and any programming that allows this usualy crashes
So... lets see what you want to perform.
we are creating the value of "C" from both "A" and "B"
we are creating the value of "B" from both "A" and "C"
we are creating the value of "A" from both "B" and "C"
It cant work
you cant create a value from nothing - to make anything you must add something to it to create it
ie. think of it this way - your mum and dad created you, thats an equation
if Mum = A and Dad = B and You are C then
A + B = C
Ok, so... now this is just an equation and dont get all religious on me but lets say you wanted to do the following equation
Mum + Son = Dad
or Son + Dad = Mum
Since Son is a product of Mum and Dad you cant use that product to create its source
Why would you need this equation, im curious?
