    <p>I am trying to make a FNF algorithm for 2d bin packing, and when I call the method I get the wrong results. Please help, I can't find the problem.</p> <pre><code>private void FFF() { int xmax = 0; int movex = 0; int movey = 0; int maxH = RectBin.Height; int maxW = RectBin.Width; List&lt;Rectangle&gt; rectsToDraw = new List&lt;Rectangle&gt;(); for (int i = 0; i &lt; Shapes.Count; i++) { int height = Shapes[i].Height; int width = Shapes[i].Width; if ((movey + height) &lt;= maxH) { rectsToDraw.Add(new Rectangle(movex, movey, width, height)); movey = movey + height; if (xmax &lt; movex + width) { xmax = movex + width; } } else if ((xmax + width) &lt;= maxW) { movex = xmax; rectsToDraw.Add(new Rectangle(movex, 0, width, height)); movey = height; xmax = movex + width; } else { Debug.Write("Message1"); break; } } for (int j = 0; j &lt; rectsToDraw.Count; j++) { Debug.Write(rectsToDraw[0]); } r2d = rectsToDraw; } </code></pre> <p>rectBin is a public rectangle (0,0, 300, 190), and Shapes[] is a public rectangle list. I sort Shapes before using it here by:</p> <pre><code>private void button9_Click(object sender, EventArgs e) { Shapes.Sort((x,y) =&gt; ((y.Width.CompareTo(x.Width)))); } </code></pre> <p>When I start FNF in the debug console I get repeating list items and message1 (first one in shapes, which shouldn't repeat), when i should get 14 items.</p> <p>Just to be clear, I am not looking for an algorithm, just someone to tell me where I made a mistake so that the first item in oblici gets coppyed 4 times into rectsToDraw and the loop ends...</p> <p>Input: {X=0,Y=0,Width=231,Height=66}{X=0,Y=0,Width=167,Height=61}{X=0,Y=0,Width=151,Height=47}{X=0,Y=0,Width=130,Height=40}{X=0,Y=0,Width=119,Height=39}{X=0,Y=0,Width=115,Height=52}{X=0,Y=0,Width=72,Height=53}{X=0,Y=0,Width=58,Height=46}{X=0,Y=0,Width=47,Height=32}{X=0,Y=0,Width=41,Height=47}{X=0,Y=0,Width=38,Height=47}{X=0,Y=0,Width=33,Height=45}{X=0,Y=0,Width=22,Height=39}{X=0,Y=0,Width=0,Height=0}</p> <p>Output: {X=0,Y=0,Width=231,Height=66}{X=0,Y=0,Width=231,Height=66}{X=0,Y=0,Width=167,Height=61}{X=0,Y=0,Width=231,Height=66}{X=0,Y=0,Width=167,Height=61}{X=0,Y=0,Width=151,Height=47}{X=0,Y=0,Width=231,Height=66}{X=0,Y=0,Width=167,Height=61}{X=0,Y=0,Width=151,Height=47}{X=0,Y=0,Width=130,Height=40}{X=0,Y=0,Width=231,Height=66}{X=0,Y=0,Width=167,Height=61}{X=0,Y=0,Width=151,Height=47}{X=0,Y=0,Width=130,Height=40}{X=0,Y=0,Width=119,Height=39}{X=0,Y=0,Width=231,Height=66}{X=0,Y=0,Width=167,Height=61}{X=0,Y=0,Width=151,Height=47}{X=0,Y=0,Width=130,Height=40}{X=0,Y=0,Width=119,Height=39}{X=0,Y=0,Width=115,Height=52}{X=0,Y=0,Width=231,Height=66}{X=0,Y=0,Width=167,Height=61}{X=0,Y=0,Width=151,Height=47}{X=0,Y=0,Width=130,Height=40}{X=0,Y=0,Width=119,Height=39}{X=0,Y=0,Width=115,Height=52}{X=0,Y=0,Width=72,Height=53}{X=0,Y=0,Width=231,Height=66}{X=0,Y=0,Width=167,Height=61}{X=0,Y=0,Width=151,Height=47}{X=0,Y=0,Width=130,Height=40}{X=0,Y=0,Width=119,Height=39}{X=0,Y=0,Width=115,Height=52}{X=0,Y=0,Width=72,Height=53}{X=0,Y=0,Width=58,Height=46}{X=0,Y=0,Width=231,Height=66}{X=0,Y=0,Width=167,Height=61}{X=0,Y=0,Width=151,Height=47}{X=0,Y=0,Width=130,Height=40}{X=0,Y=0,Width=119,Height=39}{X=0,Y=0,Width=115,Height=52}{X=0,Y=0,Width=72,Height=53}{X=0,Y=0,Width=58,Height=46}{X=0,Y=0,Width=47,Height=32}{X=0,Y=0,Width=231,Height=66}{X=0,Y=0,Width=167,Height=61}{X=0,Y=0,Width=151,Height=47}{X=0,Y=0,Width=130,Height=40}{X=0,Y=0,Width=119,Height=39}{X=0,Y=0,Width=115,Height=52}{X=0,Y=0,Width=72,Height=53}{X=0,Y=0,Width=58,Height=46}{X=0,Y=0,Width=47,Height=32}{X=0,Y=0,Width=41,Height=47}{X=0,Y=0,Width=231,Height=66}{X=0,Y=0,Width=167,Height=61}{X=0,Y=0,Width=151,Height=47}{X=0,Y=0,Width=130,Height=40}{X=0,Y=0,Width=119,Height=39}{X=0,Y=0,Width=115,Height=52}{X=0,Y=0,Width=72,Height=53}{X=0,Y=0,Width=58,Height=46}{X=0,Y=0,Width=47,Height=32}{X=0,Y=0,Width=41,Height=47}{X=0,Y=0,Width=38,Height=47}{X=0,Y=0,Width=231,Height=66}{X=0,Y=0,Width=167,Height=61}{X=0,Y=0,Width=151,Height=47}{X=0,Y=0,Width=130,Height=40}{X=0,Y=0,Width=119,Height=39}{X=0,Y=0,Width=115,Height=52}{X=0,Y=0,Width=72,Height=53}{X=0,Y=0,Width=58,Height=46}{X=0,Y=0,Width=47,Height=32}{X=0,Y=0,Width=41,Height=47}{X=0,Y=0,Width=38,Height=47}{X=0,Y=0,Width=33,Height=45}{X=0,Y=0,Width=231,Height=66}{X=0,Y=0,Width=167,Height=61}{X=0,Y=0,Width=151,Height=47}{X=0,Y=0,Width=130,Height=40}{X=0,Y=0,Width=119,Height=39}{X=0,Y=0,Width=115,Height=52}{X=0,Y=0,Width=72,Height=53}{X=0,Y=0,Width=58,Height=46}{X=0,Y=0,Width=47,Height=32}{X=0,Y=0,Width=41,Height=47}{X=0,Y=0,Width=38,Height=47}{X=0,Y=0,Width=33,Height=45}{X=0,Y=0,Width=22,Height=39}{X=0,Y=0,Width=231,Height=66}{X=0,Y=0,Width=167,Height=61}{X=0,Y=0,Width=151,Height=47}{X=0,Y=0,Width=130,Height=40}{X=0,Y=0,Width=119,Height=39}{X=0,Y=0,Width=115,Height=52}{X=0,Y=0,Width=72,Height=53}{X=0,Y=0,Width=58,Height=46}{X=0,Y=0,Width=47,Height=32}{X=0,Y=0,Width=41,Height=47}{X=0,Y=0,Width=38,Height=47}{X=0,Y=0,Width=33,Height=45}{X=0,Y=0,Width=22,Height=39}{X=0,Y=0,Width=0,Height=0}</p>

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.
