高手，请告诉我这段代码的错误

void CConn::Draw(CDC *pDC)
{
         CPen m_pen
m_pen.CreatePen(m_PenStyle,m_PenWidth,m_PenColor);
CPen* pen=(CPen*)pDC->SelectObject(&m_pen);
int oldDrawingMode=pDC->SetROP2(m_DrawingMode);
COLORREF OldColor=pDC->SetBkColor(m_BackgroundColor);
int OldBkMode=pDC->SetBkMode(m_BkMode);
COLORREF oldPenColor=pDC->SetTextColor(RGB(255,255,255));
Dll_handler=LoadLibrary("F:\\draw");
if(Dll_handler==NULL)
{
AfxMessageBox("qingjiancha"); return;
}

DLLDrawCon=(DLLDRAW)GetProcAddress(Dll_handler,"DrawCon");
DLLDrawCon(pDC,m_o_loc,m_s_color);

FreeLibrary(Dll_handler);
Dll_handler=NULL;
pDC->SetTextColor(oldPenColor); pDC->SelectObject(pen);
pDC->SetROP2(oldDrawingMode);
pDC->SetBkMode(m_BkMode);
}
这是dll的代码：
void CDrawApp::DrawCon(CDC* pDC,CPoint point,CString str)
{
pDC->MoveTo(point);
CPoint a=(100,100);

pDC->LineTo(point+a);
pDC->TextOut(point.x,point.y+10,str);}
