根据位图数据怎么构造位图句柄呢？

[everbeing]

我有两段数据
LPBITMAPINFOHEADER lpBMIH;
LPBYTE lpImage;
我得到了lpBMIH 和 lpImage的数据，但怎么根据这个来重新构造一个位图句柄呢？
我用
//构造位图句柄
HBITMAP hBitmap=CreateBitmap(lpBMIH->biWidth,lpBMIH->biHeight,lpBMIH->biPlanes,lpBMIH->biClrUsed,lpImage);
CDC* pDC=GetDC();
CDC dc;
BITMAP bmp;
dc.CreateCompatibleDC(pDC); //构建兼容DC
dc.SelectObject(hBitmap); //选入位图
GetObject(hBitmap,sizeof(BITMAP),&bmp); //得到位图信息
pDC->StretchBlt(m_rtClt.left,m_rtClt.top,m_rtClt.Width(),m-rtClt.Height(),&dc,0,0,bmp.bmWidth,bmp.bmHeight);
//绘图（注：m_rtClt是一个CRect指定的客户去)

可是这样以后一点效果也么有，好像什么也没发生一样
哪个数据 我用::StrechDIBits()绘制显示了，所以数据是正确的

呵呵 揭帖了用CreateDIBitmap

typedef struct tagBITMAPINFO              // bmi
        
{
        
           BITMAPINFOHEADER bmiHeader ;      // info-header structure
        
           RGBQUAD                      bmiColors[1] ;  // color table array
        
}
        
BITMAPINFO, * PBITMAPINFO ;

BITMAPINFOHEADER的地址就是BITMAPINFO的地址..

我好像回答得文不对题~~~~
hBitmap = CreateDIBitmap (hdc,lpBMIH,CBM_INIT,lpImage,(BITMAPINFO *)lpBMIH,DIB_RGB_COLORS) ;

The CreateDIBitmap function creates a compatible bitmap (DDB) from a DIB and, optionally, sets the bitmap bits.

HBITMAP CreateDIBitmap(
HDC hdc, // handle to DC
CONST BITMAPINFOHEADER *lpbmih, // bitmap data
DWORD fdwInit, // initialization option
CONST VOID *lpbInit, // initialization data
CONST BITMAPINFO *lpbmi, // color-format data
UINT fuUsage // color-data usage
);
