NAV 2009 Download file

JohnCon

I am trying to use the new Download to move a tempfile created from the servicetier to the users workstation.
But I get "an I/O exception occured during the operation" error message.
The error occurs on the DOWNLOAD Line, the temp file is created succcessfully in the RTC and everything works fine in the classic client.
Can anyone explain the DOWNLOAD more, the help is not too informative.

IF ISSERVICETIER THEN BEGIN
ProfileFile.CREATETEMPFILE;
ExportTxtLines;
DOWNLOAD(ProfileFile.NAME, 'Download File','C:\',Text002,FileName);
END ELSE BEGIN
ProfileFile.CREATE(FileName);
ProfileFile.CLOSE;
ExportTxtLines;
END;

The problem is, that you cannot download an open file...
Your next problem is that you cannot get the filename if the file isn't open.
And I cannot remember when we clean those files up - but the safest way is using the following construct:

// Get Temp FileName
TempFile.CREATETEMPFILE;
FileName := TempFile.NAME;
TempFile.CLOSE;

To get the filename - now create a new file in that filename., write to it, download it and delete it.
You can find more on my blog in the following post:

when i run this report in the RTC an error occured "An I/O Exception occured during the operation". pls help me from this error....

SAVEASPDF actually runs the report. You don't have to call it in the onpost report of the report itself or, guess what? the report will run itself over and over!
try to create a new codeunit and move your code in its onrun trigger. In this way you can familiarize with the saveaspdf function easily.
edit: you have to run the codeunit from the RTC, obviously (under an action in a page for example), because saveaspdf works only for rdlc reports
