Hello to all! I am new to this mail list, so my question may be answered already and I want to appologize, if it is so. I have an application (http://www.milenix.com - MyInfo 2), which uses BCBZip ver. 1.6. However there is a problem, because a single file could be opened in two instances of the program and then when the user saves the file (which is actually an archive with many files within) in one of the instances and then saves it in the other - there is a mess with the file and sometimes even the all information could be lost. I want to prevent this by gaining exclusive read-write access of the file, so it could be opened only once. There is no such option in BCBZip, but is there some way to workaround it? Thank you very much for your time! Petko Kafedjiski Milenix Software Ltd. http://www.milenix.com
