新手的一个简单问题！

[xgp1226]

我想从对话框的点（100，200），到点（300，200）之间画一条实线，请高手帮我写一下代码，谢谢！

在对话框的OnPaint里
dc.MoveTo(100,200);
dc.LineTo(300,200);

void CDlgLineDlg::OnPaint()
{
if (IsIconic())
{
CPaintDC dc(this); // device context for painting

SendMessage(WM_ICONERASEBKGND, (WPARAM) dc.GetSafeHdc(), 0);

// Center icon in client rectangle
int cxIcon = GetSystemMetrics(SM_CXICON);
int cyIcon = GetSystemMetrics(SM_CYICON);
CRect rect;
GetClientRect(&rect);
int x = (rect.Width() - cxIcon + 1) / 2;
int y = (rect.Height() - cyIcon + 1) / 2;

// Draw the icon
dc.DrawIcon(x, y, m_hIcon);
}
else
{
CClientDC pDC(this);

pDC.MoveTo(100,200);
pDC.LineTo(300,200);

CDialog::OnPaint();
}
}
