I am trying to create my own DLL with DEV-C++ IDE tool and trying to use it inside MT4 script. I tried to study the example file [MT4_HOME]\MQL4\Scripts\Examples\DLL\DLLSample.cpp available in any MT4 installation and I tried to follow the same logic with other script but without sucess. Below I am describing in great details steps i followed just to be clear. I would like to understand why following the described steps my own dll doesn't work.
System configuration
