Example #1

File: Hello.cpp Project: jiayuehua/MFCProgramming

void CMainWindow::OnPaint ()
{
	CRect rect;
	GetClientRect(&rect);


    CPaintDC dc (this);
	dc.SetViewportOrg(rect.Width()/2, rect.Height()/2);
	dc.SetBkMode(TRANSPARENT);

	for (int i = 0; i<300; i+=150)
	{
		LOGFONT lf;
		::ZeroMemory(&lf, sizeof(LOGFONT));
		lf.lfHeight = 160;
		lf.lfHeight = FW_BOLD;
		lf.lfEscapement = i;
		lf.lfOrientation = i;
		::lstrcpy(lf.lfFaceName, _T("Arial"));

		CFont font;
		font.CreateFontIndirect(&lf);

		CFont * pOldFont = dc.SelectObject(&font);
		dc.TextOut(0,0, CString(_T("M")));
		dc.SelectObject(pOldFont);
	}
