mfc如何显示raw图像，打算把raw转成bmp的

[gyk2009]

raw数据由单片机通过串口发送到PC上，黑白图像，一个像素用一个字节表示，现在串口采集数据部分都完成了。。。想请教下，接下去的图像显示方法

试下这个，转换成Bitmap的

/************************************************************************* 
* 
*  Function:  ReadRAWFile (CFile&) 
*  
*  Purpose:  Reads in the specified RAW file into a global chunk of 
*     memory. 
*          
*            Returns:  A handle to a dib (hDIB) if successful. 
*            NULL if an error occurs. 
*            
*            Comments:  BITMAPFILEHEADER is stripped off of the DIB. 
*            Everything from the end of the BITMAPFILEHEADER structure 
*            on is returned in the global memory handle. 
*

CRawdlg的类是怎么写的，获得hDIB之后，该怎么操作显示在图像控件里，刚接触这些东西，有些不懂

[傻X]

找个DIB类库，网上很多的
