Question

VC我不会，有人编译了份程序，我想把显示出的点变成一条直线或者用贴图代替，求才哥/才女帮帮小弟！

我第一次用百度，有25分，全给了！！(只是百度只让给20）很需要解决，谢谢大家！！
下面是程序，受字数限制贴了认为可能需要修改的地方，达人们看看怎么改可以实现，还需要在别的方面修改些什么。。

// If you add a minimize button to your dialog, you will need the code below

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

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

// Center icon in client rectangle

}
这里的setpixel就是画点的，lineto是画线的，不过不知道你要画什么样的线
//draw position end ////////////
CDialog::OnPaint();
}
}

// The system calls this to obtain the cursor to display while the user drags
// the minimized window.
HCURSOR CRTISIMMFCDlg::OnQueryDragIcon()
{
return (HCURSOR) m_hIcon;
}
