Monitoring directory

Hi,

My Navision application must monitoring a directory at regular interval to see if are there files, then must copy the files to another directory.

It' possible in Navision ?

Thanks, Anakin

There are three ways that I know of to accomplish tasks at regular intervals.

1: Scheduler in Service Management
2: OnTimer trigger on a form
3: Using NAS

To check if there are files in a directory you can do

FileRec.SETRANGE("Is a File", TRUE);
FileRec.SETRANGE(Path, somePath);
IF FileRec.FIND('-') THEN REPEAT
...
UNTIL FileRec.NEXT = 0;

When I had to move files around from within Navision I made it output commands to a batch file and then I ran that file from a command prompt using the shell command. Might be a better way to do it, but I don't know of one.

Hello,
take a look at File record (it's not visible in object designer).
Make a new codeunit, create a record variable with a record File, filter there directory you want to watch and run this codeunit on a scheduler.
There is one problem while watching directory - for proper working you must go to another directory and then go back, in this case File table is refreshed. (As I remember it was a problem in 3.7 version)

FileList - File record
  FileList.RESET;
  FileList.SETRANGE(Path,'C:\');
  IF FileList.FIND('-') THEN;
  FileList.RESET;
  FileList.SETRANGE(Path,PathToWatch);
  FileList.SETRANGE(Name,FileName);
  IF FileList.FIND('-') THEN
  BEGIN
  END;

Hope it helps.
