    Re: Parse CString

    Just use Find in a loop until the end of string

    Re: Number of commas

    Consider:

    Code:
    #include <atlstr.h>
    #include <stdio.h>
    
    int count(const CString& cstr, char ch)
    {
    	int cnt = 0;
    
    	for (int pos = -1; (pos = cstr.Find(ch, pos + 1)) >= 0; ++cnt);
    
    	return cnt;
    }
    
    int main()
    {
    	const CString tst = ",qw,asd,zxc,";
    
    	printf("Number of ',' in '%s' is: %i\n", tst.GetString(), count(tst, ','));
    }
    giving:

    Code:
    Number of ',' in ',qw,asd,zxc,' is: 4

    Just in continuation with this.. how to trim a given cstring by removing all the double quotes " character in it.

    example: "qw"as"dzxc" should become qwasdzxc
