SelectStr usage

ericleung · 2009-06-12

Hi,

I want to use selectstr to get the content of a comma-separated string, but if the content have repeated more than once, the function seems not work:

E.g. if the string is : 'abc,abc'
it prompt: 'STRSET' cannot contain "abc" more than once.

Do anyone know any ways to do with the function or another ways to do this??

Many Many Thanks in advance!

if you hit F1 you'll see that the help online says:

SELECTSTR treats string values as OPTIONS. This means that identical values in different strings are not allowed.

commaposition := strpos(mystring,',');
copystr(mystring,1,commaposition - 1); //copy the first value

this is stupid code, that you should elaborate in with some loops etc. to retrieve the values.
basically, copystr and strpos function will do the trick for you

Hi Eric,

I always use the following function:

SelectStr2(Number : Integer;VAR Options : Text[1024]) ExitValue : Text[1024]
i := 1;
SplitCounter := 1;
WHILE (i <= STRLEN(Options)) AND (SplitCounter <= Number) DO BEGIN
  IF Options[i] = ',' THEN
    SplitCounter += 1
  ELSE
    IF SplitCounter = Number THEN
      ExitValue += FORMAT(Options[i]);
  i += 1;
END;

Regards,

Reijer
