Milan,

From the Window API docs: (search for these defines at bcc55\include)

The CreatePen function creates a logical pen that has the specified style, width, and color. The pen can subsequently be selected into a device context and used to draw lines and curves.

HPEN CreatePen(

int fnPenStyle, // pen style
int nWidth, // pen width
COLORREF crColor // pen color
);

Parameters

fnPenStyle

Specifies the pen style. It can be any one of the following values:

Style Description
PS_SOLID Pen is solid.
PS_DASH Pen is dashed. This style is valid only when the pen width is one or less in device units.
PS_DOT Pen is dotted. This style is valid only when the pen width is one or less in device units.
PS_DASHDOT Pen has alternating dashes and dots. This style is valid only when the pen width is one or less in device units.
PS_DASHDOTDOT Pen has alternating dashes and double dots. This style is valid only when the pen width is one or less in device units.
PS_NULL Pen is invisible.
PS_INSIDEFRAME Pen is solid. When this pen is used in any graphics device interface (GDI) drawing function that takes a bounding rectangle, the dimensions of the figure are shrunk so that it fits entirely in the bounding rectangle, taking into account the width of the pen. This applies only to geometric pens.

nWidth

Specifies the width of the pen, in logical units. If nWidth is zero, the pen is a single pixel wide, regardless of the current transformation.

crColor

Specifies a color reference for the pen color.
