The EdgeExpressPCIntegrationSample solution is to demonstrate how to build a VB6 project referecing XpressLink2.dll using COM to invoke transactions.  The sample code shows how to execute a PinPad Setup, Prompt for Signature, and a Credit Sales transaction, using the reference to XpressLink2.

To intergate with XpressLink2,
	With reference:
		- Add a reference to XpressLink2.  (From the VB6 Menu, Project -> References-> Check XpressLink2)
		- Create an instance of XCharge.XpressLink2.XLEmv.  (Set variable = New XpressLink2.XLEmv)
	Without reference:
		- Create a variable as an Object type.  (Dim variable as Object)
		- Set variable to instance of XCharge.XpressLink2.XLEmv.  (Set variable = CreateObject("XCharge.XpressLink2.XLEmv"))

	- Build a XML parameter string for the transaction to execute.  See XL2 Interface Guide for supported transactions and how to build this parameter string.
	- Call the Execute method on the instance of the XLEmv object, passing in the parameter string to execute, as well as a string param to be populated with the results for the transaction.
