Can't create txt file in client

catiamatos1991

HI everyone, I'm trying to create a txt file (nav 2016) with some data and for that I tried the "Hello World" example

So in the page action I added a button called TXT with the following code:

MESSAGE('WORD');

MyFile.CREATE( 'C:\teste.txt');
MyFile.CREATEOUTSTREAM(MyOutStream);

MyOutStream.WRITETEXT('Hello World!');

MyFile.CLOSE; // To end the writing and write out to the file.
MESSAGE('END WORD');

I read that nav stores the file in NAV server instead of client. How to download or save the file in the client ? I read about soem codeunits but I'm using Nav 2016 can i use that code? Below there's a example..

https://docs.microsoft.com/en-us/dynamics-nav/walkthrough--transferring-a-file-from-microsoft-dynamics-nav-server-to-the-client

how to use this in my context? Or are any other solutions ?

Serverfilename Var Text
Archivo Var File
StreamOut Var OutStream
ClientFilePath Var Text
FileManagement Var CU419

ServerFileName:=FileManagement.ServerTempFileName('txt');

ClientFilePath:='C:\asdf.txt';

Archivo.CREATE(ServerFileName);
Archivo.CREATEOUTSTREAM(StreamOut);


StreamOut.WRITETEXT("Sales Shipment Line"."Document No.");

Archivo.CLOSE;
FileManagement.DownloadToFile(ServerFileName,ClientFilePath);

You can use the codeunit 419 (File Management), inside you have this function

DownloadToFile(ServerFileName : Text;ClientFileName : Text)

Serverfilename Var Text
Archivo Var File
StreamOut Var OutStream
ClientFilePath Var Text
FileManagement Var CU419

ServerFileName:=FileManagement.ServerTempFileName('txt');

ClientFilePath:='C:\asdf.txt';

Archivo.CREATE(ServerFileName);
Archivo.CREATEOUTSTREAM(StreamOut);


StreamOut.WRITETEXT("Sales Shipment Line"."Document No.");

Archivo.CLOSE;
FileManagement.DownloadToFile(ServerFileName,ClientFilePath);

Can u activate the debugger in order to see where the problem is?

I got the error "System.IO.File.copy" failed because I don't have access to write in "C:\teste.txt", so I create a new folder and write to "C:\teste\teste.txt" and I could download the file

The access to a root folder on any drive is restricted by default. You need Admin permissions on the system to create files in C:\ - that's why you cannot store anyting directly in C:\ folder.
