本文详细介绍了在Microsoft Foundation Classes (MFC)框架下，如何利用CStatic类创建位图静态控件。通过实例展示了从CBitmap和CImage对象加载位图到CStatic控件的过程，包括初始化、显示及后续的销毁操作。

/ Code such as this could be placed in the OnInitDialog callback.
// It creates two bitmap static controls on the heap, using members
// _m_pCStatic_A and _m_pCStatic_B to identify them so that they can
// be destroyed when no longer needed.

  CBitmap CBmp;
  CImage CImg;

  // Create a child bitmap static control and load it from a CBitmap object.
  _m_pCStatic_A = new CStatic;
  _m_pCStatic_A->Create(_T("A bitmap static control (A)"), 
      WS_CHILD|WS_BORDER|WS_VISIBLE|SS_BITMAP|SS_CENTERIMAGE, CRect(16,16,64,64),
      pParentWnd);
  CBmp.LoadOEMBitmap(OBM_CLOSE);  // Loads one of the default Windows bitmaps
  _m_pCStatic_A->SetBitmap( HBITMAP(CBmp) );
  _m_pCStatic_A->ShowWindow( SW_SHOW );

  // Create a child bitmap static control and load it from a CImage object.
  _m_pCStatic_B = new CStatic;
  _m_pCStatic_B->Create(_T("A bitmap static control (B)"), 
      WS_CHILD|WS_BORDER|WS_VISIBLE|SS_BITMAP|SS_CENTERIMAGE, CRect(90,16,138,64),
      pParentWnd);
  CImg.Load( _T("test.png") );
  if( _m_pCStatic_B->GetBitmap( ) == NULL )
    _m_pCStatic_B->SetBitmap( HBITMAP(CImg) );

  /* Then, later: 
   delete( _m_pCStatic_A );
   delete( _m_pCStatic_B );
   */
