You are not allowed to catch a <a href="http://msdn.microsoft.com/en-us/library/system.stackoverflowexception.aspx" rel="nofollow"><code>StackOverflowException</code></a> by design: <blockquote> <blockquote> Starting with the .NET Framework version 2.0, a <code>StackOverflowException</code> object cannot be caught by a try-catch block and the corresponding process is terminated by default. Consequently, users are advised to write their code to detect and prevent a stack overflow. For example, if your application depends on recursion, use a counter or a state condition to terminate the recursive loop. </blockquote> </blockquote> I’m sure there are more efficient ways of achieving this. However, to start you off, you can convert your recursion to an iteration by reifying the call stack as a <code>Stack<T></code>: <pre><code>private void fill(int xInitial, int yInitial, Color border, Color c) { var remaining = new Stack<Tuple<int, int>>(); remaining.Push(Tuple.Create(xInitial, yInitial)); while (remaining.Any()) { var next = remaining.Pop(); int x = next.Item1; int y = next.Item2; Color PointedColor = GetPixel(panel1, x, y); if (PointedColor.R != border.R && PointedColor.G != border.G && PointedColor.B != border.B && PointedColor.R != c.R && PointedColor.G != c.G && PointedColor.B != c.B && x >= 0 && x < panel1.Size.Width && y >= 0 && y < panel1.Size.Height) { SetPixel(panel1, x, y, c); remaining.Push(Tuple.Create(x - 1, y)); remaining.Push(Tuple.Create(x + 1, y)); remaining.Push(Tuple.Create(x, y - 1)); remaining.Push(Tuple.Create(x, y + 1)); } } } </code></pre>

Guidance

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.
