Change background color in CEdit (MFC)

It was a real challenge for me to make a simple change of background color for CEdit. I was suprised to find out that there are no standard function, like CEdit::SetBkColor, to do this.

1. first step is to create class derived from CEdit and declare function CtlColor:

// CustomEdit.h
class CCustomEdit : public CEdit
{
protected:
  HBRUSH CtlColor(CDC *pDC, UINT);
  DECLARE_MESSAGE_MAP()
};

2. handle WM_CTLCOLOR_REFLECT event:

// CustomEdit.cpp
BEGIN_MESSAGE_MAP(CCustomEdit, CEdit)
  ON_WM_CTLCOLOR_REFLECT()
END_MESSAGE_MAP()

HBRUSH CCustomEdit::CtlColor(CDC *pDC, UINT)
{
  COLORREF bkColor = RGB(255, 255, 255);
  pDC->SetBkColor(bkColor);
  return CreateSolidBrush(bkColor);
}
