用ExTractIconEx() 然后查帮助文件确定参数。

如果没找到API的帮助文件，去BCB的安装盘上把WIN32那个帮助文件弄下来

关于ICO转换(bmp->ico)：

if(hBit == NULL) // hBit is BitMap Handle
return NULL;

CBitmap oBitmap;
oBitmap.Attach(hBit);

CBitmap oBMap;
BITMAP rBitMap;
oBitmap.GetBitmap( &rBitMap );
oBMap.CreateBitmapIndirect( &rBitMap );
BYTE a[4096];
DWORD len = oBitmap.GetBitmapBits (4096,a);
for (UINT i=0; i<len; i++)
{
a[i] ^= a[i];
}
oBMap.SetBitmapBits( len, a);

HICON hIcon;
if (bTheBigIcon)
{
CImageList oImagelist;
oImagelist.Create(32, 32, TRUE, 1, 1);
oImagelist.Add(&oBitmap, &oBMap);

hIcon = oImagelist.ExtractIcon( 0 );
oImagelist.DeleteImageList();
}
else
{
CImageList oImagelist;
oImagelist.Create(16, 16, TRUE, 1, 1);
oImagelist.Add(&oBitmap, &oBMap);

hIcon = oImagelist.ExtractIcon( 0 );
oImagelist.DeleteImageList();
}
m_bIcon = false;
return hIcon;

好象可以用ChangFileExt();
AnsiString __fastcall ChangeFileExt(const AnsiString FileName,const AnsiString Extension);

《程序员》Borland专刊中有提到。----Delphi常见图象格式转换技术。

用ExTractIconEx()
参数index=0
搞定

何苦呢，直接用Imagelist,会帮你把位图分割掉，直接用在程序里。或者用Borland赠送的ImageEditor完全可以了啊

在网上下载Iconcool吧，可以转换，功能强大得很...
