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.

it is the code frm the book by - jeff porsise

void CMainWindow::OnPaint () { CPaintDC dc (this); CRect rect; GetClientRect (&rect); dc.DrawText (_T ("Hello, MFC"), -1, &rect, DT_SINGLELINE | DT_CENTER | DT_VCENTER); }

this the code i addded to my sdi application

i use visual studio 2005
VisualMaya
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);

}

Where exactly did you put that code
Martin Ennemoser
BEGIN_MESSAGE_MAP(CChildView, CWnd)
ON_WM_PAINT()

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!

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

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.
