delete tmp filesi have use data reports in my program
for each reports, it will generate a .tmp files how can i delete it when i exit the program? i have use Kill App.Path & "\*.tmp" but it say "permission denied" thanks "¢Ù¢×¢Ü¢Õ¢Ò¢Ý¢Û" <ad***@letskick.net> wrote in message You're probably not "cleaning up" properly.

The fact that you get a permission denied error when you try to delete them tells me that *something* still has them open and in use. This could be because there's still a valid reference to some object. I'm not familiar enough with VB's Data Reports to provide much information on it, but it would make sense to me that if a Data Report create a connection and you don't close that connection, you might have temp files that can't get deleted. -- Mike Microsoft MVP Visual Basic MikeD wrote:

Often something your application has NO business messing with. It's really not a good idea to just ASSUME because something is an obvious temp file, that you can delete it. And, for that matter, neither is it necessarily correct to ASSUME, when you can't delete some file in there, that it represents any kind of problem. An app should clean up after ITSELF. Only. Bob -- As I recall, Crystal Reports left a temp file for each report run and
wouldn't clean up after itself. The files for the current session were locked. I'd recommend the OP write a batch file to run at logon to delete those files. -- Show quoteHide quoteRandy Birch MS MVP Visual Basic http://vbnet.mvps.org/ Please reply to the newsgroups so all can participate.

Bob -- i found that the problem only happen on code area, when i pack it and
install the problem do not occur, or the tmp files is in other folders "Bob O`Bob" <filter***@yahoogroups.com> ???????:ud$zGZzQGHA.5***@TK2MSFTNGP14.phx.gbl...Show quoteHide quote > MikeD wrote: >> "¢Ù¢×¢Ü¢Õ¢Ò¢Ý¢Û" <ad***@letskick.net> wrote in message >> news:e8i4GryQGHA.4696@tk2msftngp13.phx.gbl... >>> i have use data reports in my program >>> for each reports, it will generate a .tmp files >>> how can i delete it when i exit the program? >>> i have use >>> Kill App.Path & "\*.tmp" >>> >>> but it say "permission denied" >>> >> >> >> You're probably not "cleaning up" properly.
