The Pascal Server Pages project has a unit in it that allows this if you are interested. It is not specific to Pascal Server Pages as far as I know. Basically how it works is a simple time delay is put on the file until it is free again. You can check FileShare.pp if you are intersted in a file locking read/write method. SVN: https://opensvn.csie.org/pspcgi/psp-1.5.x-devel/src/fileshare.pp For documentation on how those units would be used, check: http://z505.com/cgi-bin/psp/docs/1.4.1/psp_doc_i.cgi?p=mod.fileshare.html Again, these units and documentation were written with regards to CGI programming. However, file sharing is not specific to cgi programming of course! _______________________________________________ fpc-pascal maillist - fpc-pascal@lists.freepascal.org http://lists.freepascal.org/mailman/listinfo/fpc-pascal
