CString

[raju_shiva]

Hi all, I am trying to trim a string and store the values in some variable. i.e I have

CString str = sample(1,2,3,4,5);

I want to store the values as
x1=1,x2=2,x3=3......so on.

Any idea how can i proceed will be thankful Thanks in advance Raj

I assume you mean

CString str = sample("1,2,3,4,5");

You can use std::stringstream, ::strtok(), CString::Find(), or maybe boost::split(). Try each of them and see how they differ.

Dear, Firstly assign object of CString correctly.

The above instruction is not correct. Supposing it is:

CString str = "sample(1,2,3,4,5)"

I would use CStringT::Tokenize [^], have a look at the sample code provided. :)

Actually i am reading it from edit box as a CString. i.e CString str = "sample(1,2,3,4,5)" I am trying with this code

CString str = "sample(1,2,3,4,5)",str1,str2;

str1 = str .Left(str .Find("("));
str2 = str .Right(str .Find("("));

str.Left is working fine I am getting the result as sample But str.Right i am not getting the required result as 1,2,3,4,5). I am getting 3,4,5 What i am doing wrong Thanks Raj

Change to:

int pos = str.Find("(");
str1 = str.Left(pos);
str2 = str.Right( str.GetLength() - pos - 1);

However, I still would use Tokenize for the overall task. :)

What's wrong with assigning a variable from a function call?

[CPallini]

No problem, that's

CString sample(int a, int b, int c, int d, int e)
{
CString str;
str.Format("%d,%d,%d,%d,%d", a,b,c,d,e);
return str;
}

CString str = sample(1,2,3,4,5);
// now extract the numbers from the string!

just pure humour!

I am giving example as your requirement. eg. CString str = "sample(1,2,3,4,5)",str1,str2; int curPos= 0; str1 = str.Tokenize("()",curPos); Output: str1 = 1,2,3,4,5

Hi, Thank you for your reply. I have used for() loop and find to split the string. As i am not familar with Tokenize,thats why i did not used it. Thanks Raj
