First off my email address is [email protected] if you would like me to send the whole project. I am compiling this in a 64 but environment, but i get the same error on my 32bit laptop When compiling my project under debug mode. I get a error C2664: <pre>
'int MbusTcpMasterProtocol::eek:penProtocol(const TCHAR *const )' : cannot convert parameter 1 from 'char *' to 'const TCHAR *const '
1> Types pointed to are unrelated; conversion requires reinterpret_cast, C-style cast or function-style cast</pre>
but when i compile it under release mode i get

I believe i am linking my project properly. I have struggled with this for about a week now so any help that can be provided would be much appreciated.
