Copy newly created temp file

(1) ShareShare
ReportReport
Posted on by Morten Steengaard 551

Hi experts,

in NAV 2016 I have made a web service codeunit that creates a pdf file in the temp folder.

After DOWNLOADFROMSTREAM, I try to copy the file to another folder, but I get the error (manually translated): "The user does not have the required permission or the path is write protected".

I guess, I need to close a file or a stream, but cannot find the right one.

It works fine, if I copy any other files to the folder, that gives the error. So it must be something with the temp file.

Here is my code. Hope you can help!

var:

TempBlob: record TempBlob.

InS: Instream

OutS: OutStream

TempFileName: Text

EndingFileName: Text

TempBlob.RESET();
TempBlob.Blob.CREATEOUTSTREAM(OutS);

REPORT.SAVEAS(206, TempText, REPORTFORMAT::Pdf, OutS);
TempBlob.INSERT();
TempBlob.CALCFIELDS(Blob);
TempBlob.Blob.CREATEINSTREAM(InS);

TempFileName := 'Invoice.pdf';

DOWNLOADFROMSTREAM(InS,'','<TEMP>', '', TempFileName);

TempBlob.RESET();  // that did not help
CLEAR(InS);  // that did not help
CLEAR(OutS);  // that did not help

EndingFileName := '\\...\myShare$\' + 'Invoice.pdf';

COPY(TempFileName, EndingFileName);

    Hi Nitin.

    Thank you very much for your answer.

    On another forum, someone told me to write this, and that works:

    DOWNLOADFROMSTREAM(InS,'','<TEMP>', '', TempFileName);

    EndingFileName := '\\...\myShare$\' + 'Invoice.pdf';

    FileManagement.CopyClientFile(TempFileName, EndingFileName, TRUE);

    FileManagement.DeleteClientFile(TempFileName);

    The problem was that COPY is working on the server and the TempFileName is on the client.

    But, thank you for your time!

    Best regards,

    Morten

    First you need to save your file into ServerTemp folder like below

    FileMgt : Codeunit "File Management";

    Pfile : File;

    ltServerFileName := FileMgt.ServerTempFileName('pdf');

    pFile.TEXTMODE := FALSE;

    pFile.WRITEMODE := TRUE;

    pFile.CREATE(ltServerFileName);

    pFile.CREATEOUTSTREAM(loOutStream);

    File.COPY(TempFileName, EndingFileName)
