Refer back to the original code that I gave you. The drawing of the bar
chart was inside a CStatic derived class (CBarChart) not the dialog box
OnPaint.
So put the code back to that, place a static control or picture box on the
dialog box, then right click on it to add a variable then change the type
from CStatic to CBarChart.

Here is the link to the original post: Look at the last post on the bottom
of the page:

Do you also want to display a bitmap inside the picture box?

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);
}
