Project Description:
Attached you will find Source Code for a Motorola MT2000 Scanner.

We need to modify the source "VB_MT2000_ScanInventory".

This is what needs to be added:
1) If I change QTY it should change back to 1 after a scan

2) Show the last info that was scanned (QTY, UPC, LOC)

3) Should be able to edit or delete last Scan (Since it gets combined if UPC was already scanned, so remeber to update Qty after edit/remove)

4) make a config file that I should be able to set:
4-a) setting for "Location" (whatever location is set in this file should be set when program is opened) if setting is empty leave empty.
4-b) setting if Location is editable
4-c) setting if Location should be visible

We need all other options that is already in the source to continue to work.

There is also a problem with the code that if for any reason the unit freezes because it is full or the battery power is goes dead some scans get lost this needs to be fixed
