writeText does not recognize new line character when passing text from database

Hi,

AlivePDF recognizes \n instead of /n.
If you really want to use /n, you can use a little regexp to replace each /n 
with a \n.

let me know ;)

kind regards,

Thibault

Hi,

That was a typo...I am using \n.  Currently I store text in an Oracle database 
and 
read it in using Flex's RPC.  When it's read in from the database, ALIVEPDF 
does not 
recognize \n.  Though, if I hard code text in the writeText() method it works.

Thanks for your help.

Humm interesting, do you receive the data as XML data ? pure text ? AMF packets 
?

let me know ;)

Hi,

I have the same problem...

Hard coding works fine, but when dynamic data is used it falls over.

Is there any fix for this problems?

Im not that good at programing as a whole.. how do i use regular expressions to 
find and replace "/n"? 
i found alot of info on regex in general but not for finding and replacing non 
print chars

I had the same problem writing to a SQL Server database from a Flash multiline 
textbox and then trying to use the writeText() function in AlivePDF. The answer 
is simple once you realise what is going on with the data. Flash sends a new 
line to the database as an ascii char(13) character, which is a carriage 
return. AlivePDF is looking for a char(13) + char(10) (carriage return + 
linefeed). So to fix this problem you'll have to add a function in your 
actionscript file to convert the flash char(13) to either a char(13) + char(10) 
or just use the "\n". I've pasted in the function that I use:
private function convertString(_value:String):String
{
 var returnString:String = "";
 var _chr:String = String.fromCharCode(13);
 var tempArray:Array = _value.split(_chr);
 for(var i:uint = 0; i < tempArray.length; i++)
  {
   returnString += tempArray[i] + "\n";
  }         
  return returnString;
}
Then just call this function from your main program:
myPdf.writeText(2, convertString(textFromDatabase);

Brilliant John! Thanks for that! I was goofing around for quite a while 
replacing different characters without getting it right. How did you figure out 
what was saved in the database and what alive pdf was expecting? Loop over the 
string and somehow printing the ascii representation of each character?

Here is another version of your convertString function, using a regular 
expression rather than splitting the string and looping the array.

private function convertString(value:String):String
{
    return value.replace(/\r/g, "\n"));
}
