That looks fine to me. What sort of project did you create Did you use a template What class is handling your onpaint method If you put in a breakpoint, does it get called

This is wrong!

I guess you created a SDI Doc View program! In this case you placed the paint code in the Main frame window. The main frame window is completely covered by your View window. Place the code into your View!

According to an earlier post, his breakpoint in OnPaint() is not being hit.

If it's taking two days to address a simple issue, I'd start from scratch with a sample (Scribble ) that demonstrates OnPaint and then compare differences.

i changed the code but still same

here is message map:

BEGIN_MESSAGE_MAP(CChildView, CWnd)
ON_WM_PAINT()
END_MESSAGE_MAP()

here is onpaint part:
void CChildView::OnPaint()
{
CPaintDC dc(this);

CRect rect;
GetClientRect (&rect);

dc.DrawText (_T ("Hello, MFC"), -1, &rect,
DT_SINGLELINE | DT_CENTER | DT_VCENTER);

}
Greg Banister
BEGIN_MESSAGE_MAP(CChildView, CWnd)
ON_WM_PAINT()
END_MESSAGE_MAP()

this what u say

Did you update your message map to contain the entry for WM_PAINT

What color are you writing with If you're writing white on white, you won't see anything.
