Hi, I am still having no luck with this file. In the Boost Graph Library book (Great book!), Errata web page (http://siek.info/bgl.html) it says... "On the accompanying CD, the file \BGL\VC++ Projects\AllExamples.dsw is missing. You can download the missing file from here BGLVCprojects.tgz." When I download it I get a 454K file. When I open it with WinZip winzip tells me there is a single file BGLVCprojects.tgz in it. when it opens that single file it only finds ONE file in that accum_compile_times.dsw size 4639 bytes. this does not make sense fo r a file that started at 454K but I don't seem able to get any more out of it. I am using WinZip 6.2. Another machine with WinZIP 8.0 reports 'Invalid compressed header after 1 entry'. Is anyone else getting this result. If not could you email me a file that works for you? All the best and thanks - Richard Howells
