CFont problem

[HyperEngineer]

I would like to change the font in a static text box. But I want it to be that size until I change it again. I put the following code in the OnInitDialog() function:

  CWnd* pWndControl = GetDlgItem(IDC_PROGRESS_INDICATOR);
  pWndControl->MoveWindow(((MyRect.right - MyRect.left)/2) - 100/2,
                            MyRect.top + 100/2,
                            100,
                            100,
                            TRUE);

  CFont* pFont;
  pFont->CreatePointFont(360, "Arial", pWndControl->GetWindowDC());
  pWndControl->SetFont(pFont);

This will build fine. However, I get the following error:


The instruction at "0x5f440a1d" referenced memory at 0xccccccd0". The memory could not be "read".

I can put the same three lines of code elsewhere with differing results.

If I put it in a BN_CLICDED() then it will only change the font one time. But I get no errors or warnings at build time and no errors at run time. But, the next time I write to the static control it reverts back to the smaller font.

If I put it in the OnTimer() at build time I get this warning:

warning C4700: local variable 'MyFont' used without having been initialized

And I get the same error as before at run time.

I thought putting it in the OnInitDialog() would set the font for all time or until it was explicitly changed.

If it ain't broke, it probably needs improvement.

I got the answer to this in another forum at another website.

This is the solution FYI.

Add a control variable CStatic (m_ProgressControl) to the control, add a member variable m_pStaticFont to the dialog box.

Then in the OnInitDialog():

  m_pStaticFont.CreatePointFont(360, "Arial", pWndControl->GetDC);
  pWndControl->SetFont(&m_pStaticFont);
