Answer 1

1、OpenClipboard
2、GetClipboardData
3、WriteToBitmapif(OpenClipboard())
{
// get bmp info 
HANDLE hClipData = ::GetClipboardData(CF_DIB);
if(hClipData)
{
UINT nSize = ::GlobalSize(hClipData);
UINT nFileSize = nSize+14;
BYTE *pBmpBuf = new BYTE[nFileSize];
CopyMemory(pBmpBuf+14,hClipData,nSize);
BITMAPFILEHEADER *pBfh = (BITMAPFILEHEADER *)pBmpBuf;
pBfh->bfReserved1 = 0;
pBfh->bfReserved2 = 0;
pBfh->bfSize = nFileSize;
BYTE *pTemp = pBmpBuf;
*pTemp = 'B';
pTemp++;
*pTemp = 'M'; BITMAPINFOHEADER *pBih = (BITMAPINFOHEADER *)(pBfh+1);
pBfh->bfOffBits = nFileSize - pBih->biSizeImage; WriteToBMPFile("d:\\movie\\bmp_WithClip.bmp",pBmpBuf, nFileSize);
                           delete []pBmpBuf; } CloseClipboard();
}void CJpeg2BmpDlg::WriteToBMPFile(char *pFileName,BYTE *pBmpBuf, UINT nBmplen)
{
// open file
    HANDLE hFile = CreateFile(pFileName,//"d:\\movie\\testJPG_PngLib.bmp",
                              GENERIC_WRITE,
                              0,
                              NULL,
                              CREATE_ALWAYS,
                              0,
                              NULL);    if (hFile == INVALID_HANDLE_VALUE)
    {
        AfxMessageBox ("Could not read file");
        return;
    } DWORD dwBytesRead = 0;
BOOL bRead = WriteFile(hFile,
                          pBmpBuf,
                          nBmplen,
                          &dwBytesRead,
                          NULL);
CloseHandle(hFile);  
}
