Overview

--------

Since MT4 build 880 was released, it's no longer easy to programmatically fill

values in Login dialog.

This library hides the complicated stuff and provides

easy to use API to login to any MT4 account from within MQL4 script/expert.

How to use

----------

```c

//+------------------------------------------------------------------+

//|                                                      ProjectName |

//|                                      Copyright 2012, CompanyName |

//|                                       http://www.companyname.net |

//+------------------------------------------------------------------+

#include 

//+------------------------------------------------------------------+

//|                                                                  |

//+------------------------------------------------------------------+

void OnStart()

  {

// Just in case...

   if(loginDialogIsOpen()) closeLoginDialog();

// Let's do it!

   if(auth("ACCOUNT_NUMBER","PASSWORD","SERVER IP/HOSTNAME")) 

     {

      Print("Hooray, I found the login dialog, inserted credentials, now wait until MT4 connects :)");

        } else {

      Print("Sorry, I could not even find the Login dialog... Is your MT4 older than v880 or something?");

     }

  }

//+------------------------------------------------------------------+

```

I think I scrapped half of the Internet while researching the topic related to

WinAPI and sending keyboard input messages programmatically and I was

trying everything I stumbled upon and was closing browser tabs here and there

to keep it clean so I lost some helpful resources but the ones that helped me

significantly and that I could remember are:

- [List of VK_ constants with their human readable meaning which I used in the beginning and it helped me finding the right track](https://msdn.microsoft.com/en-us/library/windows/desktop/dd375731(v=vs.85).aspx)

- [Forum topic with someone suggesting sending WM_CHAR instead of WM_KEYDOWN](https://facepunch.com/showthread.php?t=781744)

Notes

-----

MT4 release 880 made it extremely hard to programmatically authenticate from MQL4.

It was hard before release 880 too, but this time it was even harder.

Metatrader team, please don't make our lives so hard, we have more creative stuff to

concentrate on. Let's build beautiful solutions, not hackish workarounds.
