Type error in argument 1 to `SetDIBitsToDevice';

错误提示：
Type error in argument 1 to `SetDIBitsToDevice'; found 'HWND' expected 'HDC'.

前面声明为：
BITMAPINFO info;
unsigned char *pData;

出错部分函数代码：
memset(&info,0,sizeof(info));
info.bmiHeader.biSize = sizeof(BITMAPINFOHEADER);
info.bmiHeader.biWidth = W;
info.bmiHeader.biHeight = -H;
info.bmiHeader.biPlanes = 1;
info.bmiHeader.biBitCount = 32;
info.bmiHeader.biCompression = BI_RGB;

*pData = NULL ;
if(mIndex >=0 && mIndex <5 || NULL == mImgData)
pData = mImgData + (mIndex-1)*W*H*4 ;
SetDIBitsToDevice((HWND)imghandle,0,0,704,576,0,0,0,576,pData,&info,DIB_RGB_COLORS);//这里出错了。
