Compare Exported Marketlogs by Region

Stable version: 1.6.0
Beta version: 1.7.2 - Mirror (thx to Lee Anderson)

Eve Market Scanner (EMS) is a tool to compare regional exports of marketlogs. Developed by Eraggan Sadarr of the Comply Or Die corporation. Any gratuity donations should be sent to this character.

EMS basically loads all your marketlogs (either from the default folder or from a folder you specify). Then you can select two or more regions for comparison of buy and sell orders. You can filter by quantity, system security status and export date. There are shortcuts to finding the cheapest station to buy an item in, among others.

Note: The key thing to understand is that EMS in itself only compares manually exported marketlogs. That is, there is no scraping of the cache or monitoring of the client.
Update: For those who want to run EMS in conjunction with the python cache scraper - reverence, there is an excellent script created by Mazen Alane found here and more details in the following posts. Also summarized here.

I would also be interested in the latest source code =) Thanks~

Hey folks, getting the following error pretty often now with 1.7.2

Appreciate any help or advice on trying to get it fixed

In 1.6.0 EMS i have another error:

System.OverflowException: Value was either too large or too small for an Int32.

The Int32 Bug is caused by a change in the parameters by CCP from 32 bits to 64bits. To fix it is just a matter of changing the variable in the source code to a 64bit integer.

The one about the date String is more complicated. Since Crucible was introduced the date and time has a bug in the way it's formated.

The format was 2011-12-21 but now it shows as 2NULL0NULL1NULL1NULL and so on. Open the TXT market log files and check it.

I've posted here twice about it and reported it as a bug to CCP from within EVE but so far it hasn't be fixed. Maybe if more people complaint about it they will finaly take notice.
