Thanks a lot. Your application (project1.bpr that use MMTimer.cpp) seems to be exactly what I want. I have downloaded it but i can't run it because the compiler error "unable to find Webdsnap.bpi" occurs. I have not found this file installed on my hard disk with BCB6, nor in the files you provide. Where can i find it or is it possible not to use it ? Thanks Merci beaucoup. Il est toujours agr�able de rencontrer des francophones sur les newsgroup !!!
