I don't knw which of the parameters the compiler complains about (since all input parameters to 'strstr()' usually are 'const char*'), but maybe a 'const_cast<char*>()' can help, see http://www.cprogramming.com/reference/typecasting/constcast.html

I don't think the problem is with what strstr is expecting, I think the issue is just with the part...

CStr()+uStartIndex

Open in new window


What are you trying to achieve with this? It doesn't really make sense.

Try changing that to :

const char* pszFind = strstr(CStr()+uStartIndex, pSzSearch);

Open in new window

Hi infinity08,

Yes it compiles like you suggested, I just have one question is :

this is the rest of the code , is that safe to convert it to const char* :

 if (pszFind != NULL)
    {
        uIndex = pszFind - CStr();
    }

If uIndex is a const char*, that should be ok, yes.
