A string of characters

[wateryfield]

Hi, Guys.

I was stuck by a simple VEX question.

How can i get a string attribute, such as "s + @ptnum".

s@name = "s + @ptnum" ;  not working at all.

 

I was lack of VEX expression experience.

: D 

Thanks!

strcat("string", ftoa(@ptnum))

[wateryfield]

strcat("string", ftoa(@ptnum))

Thanks, Rayman.

But s@name = strcat("s", ftoa(@ptnum));  seems not working in point wrangle.

 

AttrubCreate  can built a string attribute just use " s$PT ".

my mistake...

 

s@name = concat("s", itoa(@ptnum));

And one more question.

How can i slice the spring use VEX.

If i have a string attribute "piece88", how can i get the 88 .

 

Is any more comprehensive help page can i get some useful VEX expression.

Sometimes i was clueless when meet new problems.

well.. you can try split function, but i`m not sure it will work:

1. string[] split(string s)

2. string[] split(string s, string separators)

 

 

try something like this(I did not tested it):

string sep = "piece";
string intValue[] = split("piece88",sep);
int id = atoi(intValue[0]);

Just use doc page and use find command on your browser.

For example type "string" to search for string related functions.
