How to replace only first occurrence of character in CString?

Question

I have a CString st= $/Abc/cda/($/dba/abc)/. I want to replace only first occurrence of $ with c:\.

I have tried to replace as

st.Replace("$","c:\");

But it replaced all occurrence of $.

Could you please suggest me any logic to only replace the first occurrence of character.

Answer 1

Since you are replacing a single character by three characters, you can use CString::Find() and then CString::Delete() and CString::Insert(), like

int nInx = st.Find('$');
if (nInx >= 0)
{    st.Delete(nInx, 1);
     st.Insert(nInx, _T("C:\\");
}

Answer 2

Use

find_first_of //returns the iterator to the first occurance of string

and then

replace //to replace the iterator pointing to the first occurance
