看看你的“自定义函数”

一般可以这样定义你的自绘函数接口
void OnDraw(CDC *pDC, LPRECT rcBound);
然后调用传入CDC指针，及绘图区域

Line-Output Functions
GetCurrentPosition Retrieves the current position of the pen (in logical coordinates).
MoveTo Moves the current position.
LineTo Draws a line from the current position up to, but not including, a point.
Arc Draws an elliptical arc.
ArcTo Draws an elliptical arc. This function is similar to Arc, except that the current position is updated.
AngleArc Draws a line segment and an arc, and moves the current position to the ending point of the arc.
GetArcDirection Returns the current arc direction for the device context.
SetArcDirection Sets the drawing direction to be used for arc and rectangle functions.
PolyDraw Draws a set of line segments and Bézier splines. This function updates the current position.
Polyline Draws a set of line segments connecting the specified points.
PolyPolyline Draws multiple series of connected line segments. The current position is neither used nor updated by this function.
PolylineTo Draws one or more straight lines and moves the current position to the ending point of the last line.
PolyBezier Draws one or more Bézier splines. The current position is neither used nor updated.
PolyBezierTo Draws one or more Bézier splines, and moves the current position to the ending point of the last Bézier spline.
