如何在基于对话框的ActiveX中使用GDI + [英] How to using GDI+ in Dialog-Based ActiveX

问题描述

void CMFC_ActiveXCtrl::OnDraw(
            CDC* pdc, const CRect& rcBounds, const CRect& rcInvalid)
{
    // TODO: Replace the following code with your own drawing code.
//  m_MfcDlg.MoveWindow(rcBounds,TRUE);
//  InvalidateControl(rcBounds,TRUE);
    m_MfcDlg.m_Static.MoveWindow(CRect(rcBounds.left,rcBounds.top,rcBounds.Width()-18,rcBounds.Height()-18),TRUE);
    m_MfcDlg.SetWindowPos(NULL,rcBounds.left,rcBounds.top,rcBounds.Width(),rcBounds.Height(),SWP_NOMOVE);
}

void CMFC_Dialog::OnPaint() 
{
	CPaintDC dc(this); // device context for painting
	
	// TODO: Add your message handler code here
	GetDlgItem(IDC_DISPLAY_IMAGE)->GetClientRect(&m_rectClientRect);

//	CDC *lPdc = GetDlgItem(IDC_DISPLAY_IMAGE)->GetDC();

//	lPdc->Rectangle(m_rectClientRect.left+20,m_rectClientRect.top+20,m_rectClientRect.right-20,m_rectClientRect.bottom-20);

	Graphics lGraphics(GetDlgItem(IDC_DISPLAY_IMAGE)->GetDC()->m_hDC);

	Pen pen(Color(255,255,0));

	lGraphics.DrawRectangle(&pen,Rect(10,10,200,200));


	// Do not call CDialog::OnPaint() for painting messages
}
