Another question: CDC can have multiple GDI objects ?


A device context has a multiple GDI objects associated with it, but only one of each different obejct type. That is, there's one pen, one brush, one font etc. Each time you select a new one, it replaces the one that was previously selected. The return value from SelectObject is a pointer to the object that was previously selected, so you can select it back into the DC when you're finished with the object you selected. Here's an example using your code:

void DrawEllipse( CBitmap& outBitmap, CClientDC& dc, CPoint start, CPoint end, COLORREF color, int lineWidth ) 
{
  CDC memdc;
  memdc.CreateCompatibleDC( &dc );
  outBitmap.CreateCompatibleBitmap( &dc, 500, 500 );

  memdc.SelectObject( &outBitmap );
  memdc.FillSolidRect( CRect( 0, 0, 500, 500 ), RGB( 255, 255, 255 ) );

  CPen pen( PS_SOLID, lineWidth, color );
  CPen* oldPen = memdc.SelectObject( &pen );
  memdc.Ellipse( start.x, start.y, end.x, end.y );
  memdc.SelectObject( oldPen );

  memdc.DeleteDC();
}


Java, Basic, who cares - it's all a bunch of tree-hugging hippy cr*p
