The code I have written to draw the bargraph does draw the bars properly
when I click OnButton1.
How do I modify the code so that it will draw the bargraph inside a picture
box?
I have added a IDC_PIC1 as a picture box in my dialog.
Thanks.
This is my main code so far:
=========================================================
BOOL CMartin1Dlg::OnInitDialog()
{
CDialog::OnInitDialog();

SetIcon(m_hIcon, TRUE);
SetIcon(m_hIcon, FALSE);

  int i;
  for (i=0; i<33; i++) //initialize bars to zero
    bar[i] = 0;

  return TRUE;
}

void CMartin1Dlg::OnPaint()
{
  CPaintDC dc(this); // device context for
painting

  int SavedDC = dc.SaveDC();

  CRect cr;
  GetClientRect(&cr);

  CBrush GreenBrush(RGB(100,255,100));
  CBrush WhiteBrush(RGB(255,255,255));
  int c=15,b=5,d ; //initialize variables
  dc.SelectObject(WhiteBrush);
  dc.Rectangle(0,0,cr.Width(), cr.Height());

  dc.SelectObject(GreenBrush);
  for (b=0; b<10; b++)
  {
    dc.Rectangle(c, cr.Height()-50, c+10, cr.Height()-50-bar[b]);
    c+=d;
  }
  dc.RestoreDC(SavedDC);
}

HCURSOR CMartin1Dlg::OnQueryDragIcon()
{
return (HCURSOR) m_hIcon;
}

void CMartin1Dlg::OnButton1()
{
  int i;

  for (i=0;i<10;i++)
    bar[i]=i*10;
  Invalidate(false);
}
