Normally we would tell you to post this question in the forum at the bottom of the article: MFC Grid control 2.27[^], but I think it is ok for you to post it here as well. Although Chris is around all the time, he is obviously very busy so there is no guarantee he is able to answer your question. It is a very old project by now (it is article #8 here on CodeProject!), but I see that Chris did update it not too long ago. In your explanation of the problem, you need to include which version of Windows you are running it on an make sure to mention whether it is 32 or 64 bits. Soren Madsen
