Error Message
' function' : recursive on all control paths, function will cause runtime stack overflow

如下面代码：
#include "wingdi.h"

HPEN Graphics::CreatePen( int penStyles /*= PS_SOLID*/, COLORREF penCol /*= RGB(255, 255, 255)*/, int thickness /*= 1*/ )
{
HPEN ahPen = CreatePen(penStyles, thickness, penCol);
return ahPen;
}

这样在编译的时候，编译器会提示 warning C4717: 'GDIEngine::Graphics::CreatePen' : recursive on all control paths, function will cause runtime stack overflow

导致这样问题的原因是：编译器不知道HPEN ahPen = CreatePen(penStyles, thickness, penCol);调用的CreatePen是哪一个。

解决问题：
HPEN Graphics::CreatePen( int penStyles /*= PS_SOLID*/, COLORREF penCol /*= RGB(255, 255, 255)*/, int thickness /*= 1*/ )
{
HPEN ahPen = ::CreatePen(penStyles, thickness, penCol);
return ahPen;
}
