    <p>I have a simple object that allows you to assign three properties (x,y,z) (lets call this object a "point", because that is what it is). I then have a second object with a method that accepts two instances of the first object, and returns the distance between the two "points" in three dimensional space. I also need a method that will accept two "points" and a double, representing distance traveled (from the first "point" parameter used) that returns a "point" object with its x,y,z coordinates.</p> <p>I'm ok with everything except the calculation of the point coordinates that are on the original line between the two points supplied, that is at a certain distance from the first point.</p> <p>"point" object:</p> <pre><code>public class POR { private double PORX; private double PORY; private double PORZ; public double X { get { return PORX; } set { PORX = value; } } public double Y { get { return PORY; } set { PORY = value; } } public double Z { get { return PORZ; } set { PORZ = value; } } public POR(double X, double Y, double Z) { PORX = X; PORY = Y; PORZ = Z; } </code></pre> <p>I'm then using : </p> <pre><code> public double PorDistance(POR por1, POR por2) { return Math.Round(Math.Sqrt( Math.Pow((por1.X - por2.X),2) + Math.Pow((por1.Y - por2.Y),2) + Math.Pow((por1.Z - por2.Z),2)),2); } </code></pre> <p>to return the distance between those two points I need something like</p> <pre><code>public POR IntersectPOR (POR por1, POR por2, double distance) { } </code></pre> <p>where distance is the distance traveled from por1 towards por2.</p>

    1. COCan you post some code to show us what you have so far? This sounds a bit like homework...

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
