That's complicated, what would you recommend me to do? I mean I did all that's recommended to do, can you give me some step-by-step tutorial of how to compile the program which will download the data and save it in good way to produce the database? What are .dll files used for?
EDIT: Please.

Ok, I got to this: #include <iostream>
#include <Windows.h>
#include <conio.h>
using namespace std;
typedef int (*MsgFunction)(int);
HINSTANCE hinstDLL ;
int main()
{
MsgFunction MsgBox(0) ;
hinstDLL = LoadLibraryA("FXCM.dll") ;
if(hinstDLL != 0)
{
MsgBox = (MsgFunction)GetProcAddress(hinstDLL, "MsgBox");
}
if(MsgBox == 0)
{
cout << "MsgBox is NULL \n";
}
int x = MsgBox(5);
if(x == 5)
{
cout << "Message Displayed! \n" ;
}
FreeLibrary(hinstDLL) ;
return 0 ;
getch() ;
} Works, how do I call BrokerOpen function, because I get this after I try to run the file

For BrokerOpen you need a different function type: typedef int (*BROKER_OPEN)(char* Name,FARPROC fpError,FARPROC fpProgress); and then
BROKER_OPEN BrokerOpen = (BROKER_OPEN)GetProcAddress(h,"BrokerOpen");
if(BrokerOpen) {
char brokername[50] = "";
long version = (*BrokerOpen)(brokername,NULL,NULL);
}
You can see on the "Broker Plugin" page which functions you have and how they must be typedef'd. For your purpose you only need BrokerLogin, BrokerAsset, and BrokerHistory.

#include <iostream>
#include <Windows.h>
#include <conio.h>
using namespace std;
typedef int (*MsgFunction)(int);
typedef int (*BROKER_OPEN)(char* Name,FARPROC fpError,FARPROC fpProgress);
HINSTANCE hinstDLL ;
int main()
{
MsgFunction MsgBox(0) ;
hinstDLL = LoadLibraryA("FXCM.dll") ;
if(hinstDLL != 0)
{
MsgBox = (MsgFunction)GetProcAddress(hinstDLL, "MsgBox");
}
if(MsgBox == 0)
{
cout << "MsgBox is NULL \n";
}
int x = MsgBox(5);
BROKER_OPEN BrokerOpen = (BROKER_OPEN)GetProcAddress(hinstDLL,"BrokerOpen");
if(BrokerOpen)
{
char brokername[50] = "";
long version = (*BrokerOpen)(brokername,NULL,NULL);
}
if(x == 5)
{
cout << "Message Displayed! \n" ;
}
FreeLibrary(hinstDLL) ;
return 0 ;
getch() ;
} I got problem with higlighted part, you wrote h but it didn't work, I have tried to put it into as a variable-didn't work, so I put hinstDLL and when I try to run it with FXCM.dll it gives me: "Message box is NULL". EDIT: When I keep it this way #include <iostream>
#include <Windows.h>
#include <conio.h>
using namespace std;
typedef int (*MsgFunction)(int);
typedef int (*BROKER_OPEN)(char* Name,FARPROC fpError,FARPROC fpProgress);
HINSTANCE hinstDLL ;
int main()
{
MsgFunction MsgBox(0) ;
hinstDLL = LoadLibraryA("FXCM.dll") ;
if(hinstDLL != 0)
{
MsgBox = (MsgFunction)GetProcAddress(hinstDLL, "MsgBox");
}
if(MsgBox == 0)
{
cout << "MsgBox is NULL \n";
}
int x = MsgBox(5);
if(x == 5)
{
cout << "Message Displayed! \n" ;
}
BROKER_OPEN BrokerOpen = (BROKER_OPEN)GetProcAddress(h,"BrokerOpen");
if(BrokerOpen)
{
char brokername[50] = "";
long version = (*BrokerOpen)(brokername,NULL,NULL);
}
FreeLibrary(hinstDLL) ;
return 0 ;
getch() ;
} I get this: 1>------ Build started: Project: DLLtutApp, Configuration: Debug Win32 ------
1> main.cpp
1>c:\users\master roshi\documents\visual studio 2010\projects\dlltutapp\dlltutapp\main.cpp(34): error C2065: 'h' : undeclared identifier

Okay, sorry, I thought it was ment to be added in. I'll work on it, as you've said, in terms of tutorials provided by website, is there everything I need?
