Hi Folks,

Does anyone know how to delete a external file within Navision. Everytime i run a dataport to export records and if the file already exist on my C: drive system gives a message 'File already exist. Do you want to overwrite'. I want to delete the file evertime i run the dataport.

Has anyone done this kind of modification. Any help is really appreciated.

Thanks

Best regards
Suresh.

    IF EXISTS(CurrDataport.FILENAME) THEN
  ERASE(CurrDataport.FILENAME);
    Remark: Erase has an optional return value.

    Create a codeunit
    First step: delete the existing file
    example: ERASE('c:\Testfile.txt');
    Second step: Launch the dataport
    example: dataport.run(50000)

    It's much easier and logical to do: 
    CurrFile.QUERYREPLACE(FALSE);
    in OnInitDataport or OnPreDataport.

    Nice one Nelson!

    This way the user is "notified" of a possible mistake!

    hey nelson,

    really nice code - works well. But it doesn´t work if I call it via Navision batch. At least in my Navision 3.7.
    The batch ist stopped and is waiting for input (overwrite? Y/N). Just like your code ist ignored.
    Any ideas?!
