I used angle arc to divide circle into 8 segments, when i extend an angle of one angle arc then the other dissappears , it does not overwrites what to do? What I have tried: i used the below code MoveToEx(hMemDC,50,50 , (LPPOINT) NULL); AngleArc(hMemDC, 50 , 50 , 47, 0, 45); SetArcDirection(m_hMemDC, AD_CLOCKWISE); LineTo(hMemDC,50,50); EndPath(hMemDC); StrokeAndFillPath(hMemDC); then MoveToEx(hMemDC,50,50 , (LPPOINT) NULL); AngleArc(hMemDC, 50 , 50 , 47, 45, 45); SetArcDirection(m_hMemDC, AD_CLOCKWISE); LineTo(hMemDC,50,50); EndPath(hMemDC); StrokeAndFillPath(hMemDC); and so on.. now if i want to increase the angle of 2nd segment to 55 degrees then the 3rd segment dissappears. how to solve it ?
