Hi guys,
I've been stuck on that for a little while and I hope someone can help me.
I'm using NAV 2009 R2.
I need to read/write notes in a codeunit. This codeunit is then going to be used by a web service.
This is my function to write a note

NotificationText.ADDTEXT(NotificationText2);
RecordLink.INIT;
RecordLink.”Record ID” := RecRef.RECORDID;
RecordLink.URL1 := CreateURL(RecRef,ObjectID);
RecordLink.Description := Caption;
RecordLink.Type := RecordLink.Type::Note;
RecordLink.Created := CURRENTDATETIME;
RecordLink.”User ID” := USERID;
RecordLink.Company := COMPANYNAME;
RecordLink.Notify := TRUE;
RecordLink.”To User ID” := USERID;
RecordLink.INSERT(TRUE);
RecordLink.Note.CREATEOUTSTREAM(OutStream);

Encoding := Encoding.GetEncoding(437);
BinaryWriter := BinaryWriter.BinaryWriter(OutStream,Encoding);
BinaryWriter.Write(FORMAT(NotificationText));
OutStream := BinaryWriter.BaseStream;

RecordLink.MODIFY();

My parameters are
RecRef RecordRef
ObjectID Text 50
NotificationText2 Text 1024
Caption Text 50

and my variables are
OutStream OutStream
BinaryWriter DotNet ‘mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089′.System.IO.BinaryWriter
Encoding DotNet ‘mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089′.System.Text.Encoding
RecordLink Record Record Link
NotificationText BigText

My issue is on this line:
BinaryWriter := BinaryWriter.BinaryWriter(OutStream,Encoding);

I get this error: Unknown Type ''.
Does anyone know what is the issue?
Thanks guys

    We did provide a similar piece of code in NAV2013, codeunit 454 "Job Queue - Send Notification", where the Job Queue sends a notification to the user. The message format is in RTF, which includes one or two leading bytes of information about the message length.

    Sorry for the late answer.
    The code I've posted is working for NAV 2013 but it is not working for NAV 2009.
    So, after spending hours trying to find a solution I actually gave up and used the comments instead of the notes. Much easier to manage.

    Still interested to know if there is a solution though.
    Cheers

    It seems I have the same error, but the line it errors out to is the following: Encoding := Encoding.GetEncoding(437);

    It appears because Encoding doesn't have a constructor, NAV2009 cannot handle it.

    Try

    Encoding := Encoding.Default;

    to construct the Encoding variable.

    While I can't say this is the correct way... I have found a solution. I found the unknown type to be in line "BinaryWriter.BinaryWriter(OutStream,Encoding)", the unknown being the Variable: "Outstream - DataType Outstream". I created another variable, "Outstream1 Datatype DotNet - 'mscorlib, Version=2.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089'.System.IO.Stream" and modified the code as shown:
      Note.CREATEOUTSTREAM(OutStream);
  OutStream1 := OutStream;
  
  Encoding := Encoding.GetEncoding(437);
  BinaryWriter := BinaryWriter.BinaryWriter(OutStream1,Encoding);
  BinaryWriter.Write(FORMAT(Notification));
  OutStream := BinaryWriter.BaseStream;

    Sog, while I didn't get an unknown error in line Encoding := Encoding.GetEncoding(437);, I did receive an error when I originally pasted and copied the dotnet variable. GetEncoding was not an my Encoding C/AL Symbols menu. I entered manually to ensure it was pasted correctly, found what I had pasted was not my Processor Architecture type. Not sure if you reviewed already, but thought I would mention just in case.

    Hope this helps!

    Not entirely related but I got the unknown type '' error when trying to call a function with a string parameter.
    Works in newer version but not 2009. Instead of calling it with a text variable, I made it a big text and assigned the text to it with addText, like this:

    gFolderPath.ADDTEXT(edisetup."XML Source Document Folder");

    After that it was OK to use it without error:

    obj := fold.GetFiles(gFolderPath);
