Draw a randomly colored Sierpinski pentagon in C#
The example Draw a colored Sierpinski pentagon in C# lets the user click on the parts of a Sierpinski pentagon to change their colors. Eddie Bole thought it would be interesting to color the larger pentagons in addition to the … Continue reading

Draw a colored Sierpinski pentagon in C#
The example Draw a Sierpinski pentagon in C# shows how to draw a Sierpinski pentagon. This example modifies that one so the user can click on pentagons to change their colors. To do that, this program takes a very different … Continue reading

Draw a Sierpinski pentagon in C#
In a Sierpinski pentagon, larger pentagons are recursively divided into five smaller pentagons with a sixth uncolored pentagon in the center. The following picture shows the first four levels of the resulting fractal. For this example, I decided to think … Continue reading

Enumerate TreeView nodes in C#
The previous two posts show two ways you can enumerate TreeView nodes that are checked. The idea is to recursively crawl over the tree’s nodes and pick out the checked ones. Unfortunately that method isn’t easily extendable. For example, if … Continue reading

Yield checked TreeView nodes in C#
The previous example used recursion to traverse the nodes in a TreeView control and fill a list with the nodes that are checked. This example uses a slightly different approach. It traverses the TreeView control’s nodes and uses the yield … Continue reading
