Dear Experts,
one more small query,

i want to convert a delimeter from string to int, how to do,
i am reading the delimeter in the form of string but my other module,
requires it in the form of int how to do that,
means i have

Code:

string delim=",";
but i want
 int delim=',';

how to achieve this please help me.

Code:

string delim_string = ",";
int delim_char_code = delim_string[0];

As to your other problem, can you post a complete and compilable example that gives the same error? It sounds like maybe you're not building correctly or linking to the right libraries, but it would be good to verify that the code itself is correct.
