: Working on a Delphi Application where I have 5 parameters and 5 Edit boxes. It takes any two parameters to compute the remaining Parameters.

: Example:
: Editbox1 = Angle
: Editbox2 = Radius
: Editbox3 = Tangent
: Editbox4 = Arc
: Editbox5 = Chord

: If I enter (Angle) in Editbox1
: and enter the (Chord) in Editbox5 then I can compute the (Radius), (Tangent), and (Arc).
: I think this requirs a series of IF and ELSE statements but I have not been able to get organized on how to do this. Anyone knowing how this could be setup I would appreciate the help.

If only two of the edit-boxes contain text, then it's not so difficult to find out how to calculate the others. I'll come back to this in a next message tomorrow.

But... what do you want to happen if more then 2 edit boxes contain something? Should the program take the first two edits that contain something? Or should the program say: please, clear 3 boxes?

Another possible solution: put 5 check boxes next to the edit boxes. Now, the user must click 2 check boxes.
- if less than 2 are checked, the program looks if there are only 2 edits that are filled, and calculates the rest;
- in "non defined" states, show an error message (for example: more than 2 edits used and more or than 2 checkboxes checked).

Any other ideas, before we start with ideas for the coding?
