yes,the pData should be pData=new unsigned char[768*576*3],but after above update,I am fail to create the DIB bitmap again, I LOVE VC

I got a error that there was a ASSERT error in the line of "CreateDIBitmap()", I am fail to create a DIB bitmap and display it in the monitor. I LOVE VC

you should also delete the cpp&h files in the "FILEVIEW" of workspace view(which containing three view,Class view,resource views,fileview),delete the cpp file in the "Soure Files",and delete the h file int the "Header files".Following above steps, you will not get the compilatin error.
