ms access - Is there a way for a .mdb file to be emptied by itself -

-

i must read .mdb file on 15 minutes interval. problem file emptied each day @ 15:45 pm. , somehow loose data in interval gap.

i have searched cron jobs/scheduled task on server , found nothing know if there way set .mdb database empty @ specific time?

thanks

there no built-in way configure access database empty itself. has done either vba-code/macros inside database or external application/script accessing database , deleting everything.

if database emptied @ specific time without user interaction, there has kind of scheduled task this.

if absolutely data deleted, might possible whole database overwritten fresh/empty template somewhere. - still has done scheduled task.

if database stored on network share, accessible other computers, task deleting data might run on computer.

Deploying Qt Application on Android is really slow? -

-
as may know there 3 ways deploy qt application on android : use ministro service install qt deploy local qt libraries temporary directory bundle qt libraries in apk the first method takes 30 seconds , needs install apk . ministro . second takes 1 minute me ! , anytime try run program qt creator pushes qt libraries device. third 1 makes .apk file big , again takes 1 minute me. think situation that's not reasonable develop android application using qt. there way make deploying process faster? almost full year since op , things have not changed @ all. deployment of 7 mb apk takes on minute , half project compiles in 5 seconds. reason answering not problem got resolved, offer alternative solution. i've implemented "workaround" consisting of 2 applications work in tandem - 1 on pc , 1 on device - created compile files remotely, turned out faster alternative deployment well. on host create application launches compilation in separate process, when do...
