Hi,

In our company, we are using a translation DLL in order to get values for different languages. Our latest client is from Finland, so we need to translate the system to finish. 

From the DLL we get a converted string like this "Olet valinnut MRI-haun, mutta et ole määrittänyt hakuehtoja.~n~rVoit etsiä koko tietokannasta..." into a variable, then we assign this variable to the Text property of a multilineedit object. It seems that the control is not able to recognize the "~n~r" in order to add a new line when renderizing. We would like to have the message splited into two different lines.

It's strange, if I direclty assing a string with  "~n~r" then it is correctly shown on the screen.

Is there something I can do to correctly display string recovered from the DLL (or database)?

 

Thanks.

Hi Gaston;

Nothing Chris, still the same error. But now the string looks like this:



"Olet valinnut MRI-haun, mutta et ole määrittänyt hakuehtoja.~r~rVoit etsiä koko tietokannasta, mutta tämän hakeminen voi kestää useita minuutteja. Voit nopeuttaa hakua merkittävästi antamalla osittaisen sukunimen, sukupuolen, yksikön numeron tai osittaisen sukunimen ja syntymäajan.~r~rHaluatko antaa lisätietoja?"

Hi, Gastón -

Have you verified that the DLL is returning a Carriage-Return/New-Line (~r~n) sequence, not simply a New-Line character?

What encoding is used for the string that is returned from the DLL? PB uses Unicode 16LE encoding internally.

Best regards, John

I finally get to a workaround. I just pre-process the string before assign it to the MLE.

 

ls_string = Replace(inv_errorattrib.is_text, pos(inv_errorattrib.is_text, "~~r~~n"), 4, CHAR(13)+CHAR(10))
ls_string = Replace(inv_errorattrib.is_text, pos(inv_errorattrib.is_text, "~~t"), 3, CHAR(9))

That code make the trick.

 

Thanks.

Hi Gastón;

Thanks for providing the solution. I've never seen this requirement before with the double tildes but I wonder if it's because of the language / translation features in effect.

Glad that you found a solution!

Regards ... Chris
