how to export a long string into txt file?

icapilla · 2012-06-12

Hi,
I'm trying to export a long string into txt file with a report. I declarated the following local variables :
Cadena1, text 1024
Cadena2, text 1024
Cadena3, text 1024

The section of code where i get the error is the following :

OutFile.WRITE(Cadena1+Cadena2+Cadena3);

When i execute the report, it gets the following error:

"there is not sufficient available space in the c/al stack memory to execute this task.
there are too many simultaneous activities,due to the way recursive function call is used in the program. the problem can by solved temporarily by shutting down some of the open activities(but the function still cannot be executed)."

thank you in advance for your suggestions.

Look at the CREATEOUTSTREAM function in NAV. This is what you need.

hi Alex Chow!

I´m a fellow of icapilla.

We have this code...

OutFile.CREATEOUTSTREAM(OStream);
OStream.WRITETEXT(Cadena1+Cadena2+Cadena3);

But the error continue...

If i only write this...
OutFile.CREATEOUTSTREAM(OStream);
OStream.WRITETEXT(Cadena1+Cadena2);

the file can be created but if write OStream.WRITETEXT(Cadena1+Cadena2+Cadena3) the error appears..

The total string is about 2500 characters

We need some help plz... ](*,)

Of course you can not add all texts at the same time. This will exceed the limit of NAV string as well. Try this instead (adding by portions):

MyFile.CREATE('C:\Temp\dump.txt');
MyFile.CREATEOUTSTREAM(outstrm);

YourCondition := ...;

while (YourCondition) do begin
  TextPortion := 'text portion ';
  OutStrm.WRITETEXT(TextPortion);

  YourCondition := ...;
end;

MyFile.CLOSE;

Try this:

OutFile.CREATEOUTSTREAM(OStream);
OStream.WRITETEXT(Cadena1);
OStream.WRITETEXT(Cadena2);
OStream.WRITETEXT(Cadena3);
OutFile.CLOSE();

Or you can write it in Binary mode char by char, in this mode you can write line as long as you want...

Thanks for your suggestions, my problem it's solved,
i solved the problem with this sequence of code:

OutFile.CREATEOUTSTREAM(OStream);
    REPEAT
      CR := 13;
      LF := 10;
      OStream.WRITETEXT(Cadena1);
      OStream.WRITETEXT(Cadena2);
      OStream.WRITETEXT(Cadena3);
      OStream.WRITETEXT(FORMAT(CR) + FORMAT(LF));
    UNTIL VARIABLE.NEXT = 0;
