Convert MFC CString to integer

Question

How to convert a CString object to integer in MFC.

Answer 1

i've written a function that extract numbers from string:

int SnirElgabsi::GetNumberFromCString(CString src, CString str, int length) {
   // get startIndex
   int startIndex = src.Find(str) + CString(str).GetLength();
   // cut the string
   CString toreturn = src.Mid(startIndex, length);
   // convert to number
   return _wtoi(toreturn); // atoi(toreturn)
}

Usage:

CString str = _T("digit:1, number:102");
int  digit = GetNumberFromCString(str, _T("digit:"), 1);
int number = GetNumberFromCString(str, _T("number:"), 3);
