Hi Guys
OK, got a little issue with a service I've written that watches a folder for inbound text files and imports them into a database.
I use fListFile to get a string from which I build an array of files to process
I use fOpen with foReadWrite + foReadLock + foWriteLock so that theoretically, no other program can access it while I'm reading the data.
When the data is successfully processed, I fClose then use fDelete to temove it.
This code has been running since about WD12
I now have an issue where I am importing 2 copies of the file into the database.
Adding some extra debug code with additional fListFile after processing, the file is initially correctly gone ( and fFileExist is false). However milliseconds later another fListFile finds it again!
I have tried modifying the code to rename and delete the renamed file, which again reports success, but the file(s) still mysteriously appear.
Anyone else have similar issues?
I am about to try deleting via ExeRun or API and see what happens.
Also, I might put a pause in the looping, but would like to avoid this as performance is a factor.
Cheers

Hi Malc,
Try to consider some issues:
1) After executing fDelete, the operative system take some time to delete the file (maybe you need to increase the duration between cals?);
2) Try to use fdir to get the files in the directory. By experince, I know it is a lot faster;

OK, tried ExeRun and fFileExist to check deletion. Still re-appears.
I'm guessing something has changed on the server re caching or file indexing or something which is flushing the file back to disk
Next step is a pause in the loop <img src="/NG2013_WEB/ui/smiley/2.gif" align=absmiddle border=0 alt=":("> |
