 strcat(path,"文件路径");

Answer 1

LoadImage
The LoadImage function loads an icon, cursor, animated cursor, or bitmap.HANDLE LoadImage(
  HINSTANCE hinst,   // handle to instance
  LPCTSTR lpszName,  // image to load
  UINT uType,        // image type
  int cxDesired,     // desired width
  int cyDesired,     // desired height
  UINT fuLoad        // load options
);

Answer 2

我用过,没问提 // TODO: Add your control notification handler code here
HBITMAP hBmp,oldBmp; hBmp=(HBITMAP)LoadImage(::AfxGetInstanceHandle(),"c:\\1.bmp",IMAGE_BITMAP,
0,0,LR_LOADFROMFILE|LR_CREATEDIBSECTION);
CDC memDc,dc; CRect m_rect;
dc.CreateDC("DISPLAY",NULL,NULL,NULL);
memDc.CreateCompatibleDC(&dc);
GetWindowRect(m_rect);
oldBmp=(HBITMAP)memDc.SelectObject(hBmp);
//show
dc.BitBlt(100,100,m_rect.Width()-20,m_rect.Height()-20,
&memDc,0,0,SRCCOPY);

Answer 3

CBitmap bmSplash;
HBITMAP hBitmap = (HBITMAP)LoadImage(NULL,lpPathFile,IMAGE_BITMAP,0,0,LR_CREATEDIBSECTION|LR_DEFAULTSIZE|LR_LOADFROMFILE);
    bmSplash.Attach(hBitmap);

Answer 4

CBitmap bmSplash;
HBITMAP hBitmap = (HBITMAP)LoadImage(NULL,lpPathFile,IMAGE_BITMAP,0,0,LR_CREATEDIBSECTION|LR_DEFAULTSIZE|LR_LOADFROMFILE);
    bmSplash.Attach(hBitmap);
