*  This example requires the Chilkat API to have been previously unlocked.
*  See Global Unlock Sample for sample code.

*  First, Chilkat recommends downloading the MGTEK Smartcard Minidriver Tool to get information 
*  about your smartcard. 

*  The tool can be downloaded from https://www.mgtek.com/smartcard

*  --------------------------------------------------------------------------------------------------------
*  1. Select the smartcard as shown below and send Chilkat a screenshot of the basic smartcard information.
*  --------------------------------------------------------------------------------------------------------
*

*  
*  --------------------------------------------------------------------------------------------------------
*  2. Select the cmapfile (if present) as shown below and send Chilkat a screenshot of the CSP container map
*  --------------------------------------------------------------------------------------------------------

*  ---------------------------------------------------------
*  Chilkat provides functions to get information about the smartcard, and what it contains.
*  Send Chilkat the output of the following source code:

loScmd = CreateObject('Chilkat.ScMinidriver')

*  Reader names (smart card readers or USB tokens) can be discovered
*  via PCSC List Readers or PCSC Find Smart Cards
lcReaderName = "Alcor Micro USB Smart Card Reader 0"
lnSuccess = loScmd.AcquireContext(lcReaderName)
IF (lnSuccess = 0) THEN
    ? loScmd.LastErrorText
    RELEASE loScmd
    CANCEL
ENDIF

loJson = CreateObject('Chilkat.JsonObject')
loJson.EmitCompact = 0

*  ------------------------------------------------------
*  3. Send Chilkat the JSON returned by GetCardProperties
*  ------------------------------------------------------
lnSuccess = loScmd.GetCardProperties(loJson)
IF (lnSuccess = 0) THEN
    ? loScmd.LastErrorText
    RELEASE loScmd
    RELEASE loJson
    CANCEL
ENDIF

? loJson.Emit()

*  ------------------------------------------------------
*  4. Send Chilkat the JSON returned by GetCspContainerMap
*  ------------------------------------------------------
loJson.Clear()
lnSuccess = loScmd.GetCspContainerMap(loJson)
IF (lnSuccess = 0) THEN
    ? loScmd.LastErrorText
    RELEASE loScmd
    RELEASE loJson
    CANCEL
ENDIF

? loJson.Emit()

RELEASE loScmd
