extern "C" void _declspec(dllexport)OpenFile(char* filename);
The above looks "odd"...
The MT4 sample dll uses:
#define MT4_EXPFUNC __declspec(dllexport)
MT4_EXPFUNC char* __stdcall OpenFile(char *filename)
I have no idea if yours is "correct" or not.

i wrote a simple dll to open an a file
tou.cpp
#include "tou.h"
void OpenFile(char* filename)
{
ShellExecute(NULL, "open", filename, 0, 0, SW_SHOWDEFAULT);
}
tou.h
#include <windows.h>
#include <shellapi.h>
#pragma comment(lib, "shell32.lib")
#ifndef TOU_H
#define TOU_H
extern "C" void _declspec(dllexport)OpenFile(char* filename);
#endif
i have build a dll. but when i use it from indicator it opened the file then mt4 crashed.
the some souce of the test indicator:
#import "tou.dll"
void OpenFile(string filename);
#import
