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

    ; Chilkat recommends the following free tool for interactively examining the contents of your smart card
    ; through the ScMinidriver interface:  MGTEK Tool for Minidriver enabled Smart Cards

    ; Let's first look at our smart card..
    ; Here's the view of the card we happen to be using: a Gemalto (Thales) IDPrime MD T=0 smart card.

    

    scmd.i = CkScMinidriver::ckCreate()
    If scmd.i = 0
        Debug "Failed to create object."
        ProcedureReturn
    EndIf

    ; First we need to acquire a context to the smart card in the reader where it is inserted.
    ; Reader names (smart card readers or USB tokens) can be discovered
    ; via List Readers or Find Smart Cards
    readerName.s = "Alcor Micro USB Smart Card Reader 0"
    success.i = CkScMinidriver::ckAcquireContext(scmd,readerName)
    If success = 0
        Debug CkScMinidriver::ckLastErrorText(scmd)
        CkScMinidriver::ckDispose(scmd)
        ProcedureReturn
    EndIf

    ; If successful, the name of the currently inserted smart card is available:
    Debug "Card name: " + CkScMinidriver::ckCardName(scmd)

    ; To delete the contents of a key container, we'll need to be PIN authenticated..

    ; For more details about smart card PIN authentication, see the Smart Card PIN Authentication Example
    pinId.s = "user"
    retval.i = CkScMinidriver::ckPinAuthenticate(scmd,pinId,"0000")
    If retval <> 0
        Debug "PIN Authentication failed."

        CkScMinidriver::ckDispose(scmd)
        ProcedureReturn
    EndIf

    ; Let's delete the contents of key container #7
    ; This deletes both keys (signature key and "key exchange" key) that might be present in the key container.
    ; (It is not possible to delete just one or the other.)
    success = CkScMinidriver::ckDeleteKeyContainer(scmd,7)
    If success = 0
        Debug CkScMinidriver::ckLastErrorText(scmd)
