This should do it for you:

'just a solid brush: Using br = New SolidBrush(Colors.Black) e.Graphics.FillRectangle(br, New Rectangle(50, 50, 10, 10)) End Using 'A red -> orange gradient, at 45 degrees: Using br = New LinearGradientBrush(new Rectangle(50, 50, 10, 10), Color.Red, Color.Orange, 25) e.Graphics.FillRectangle(br, New Rectangle(50, 50, 10, 10)) End Using 

Answer 2

A brush is a fill painting style that includes both color and pattern. The pen is similar to a brush, but defines a line drawing style. To switch from color to brush, you need to create a new brush and give it a color. The Brush class itself is abstract; its child classes define various basic, custom drawing patterns. The handles are similar, but as the lines are drawn as if they were filled with rectangles, a brush may be required to adjust the “fill” of the line. Then the Pen object has additional properties that determine the style characteristic of drawing a line. Take a look at MSDN: http://msdn.microsoft.com/en-us/library/d78x2d7s%28v=VS.71%29.aspx

Answer 4

These are completely different things.

Here is an article entitled "Pens, Brushes, and Colors," http://msdn.microsoft.com/en-us/library/aa983677(v=vs.71).aspx

Pens
The pen is used to draw lines, curves, and contour shapes.

Brushes
Brushes are objects that are used with the Graphics object to create solid shapes and to render text.

Both pens and brushes have a “color” that they use ... but you cannot turn the color into a brush. It is like a car. You cannot turn “Red” into a car, but the car may be red.

Answer 5

a brush is used to fill the inner area of ​​a closed drawing.
Color is color.

The brush and pen may have the same color, but their role is different
