Entry::GetPrevTickInfo

Gets the previous tick information.

VARIANT_BOOL GetPrevTickInfo (
    VARIANT* pvSession,
    VARIANT* pvSequence,
    VARIANT* pvTickDate,
    VARIANT* pvTickUser,
    VARIANT* pvAmountDetC,
    VARIANT* pvAmountDosC,
    VARIANT* pvTickSysNums
)

Parameters

pvSession

[in,out] The session of which you want to get the previous tick information.

In: A LONG containing the tick session number of the tick session returned by GetLastTickInfo.

Out: Returns a VARIANT, subtype LONG, containing the tick session number of the previous tick session.

pvSequence

[out] Returns a VARIANT, subtype LONG, containing the sequence number within the tick session (0 based).

pvTickDate

[out] Returns a VARIANT, subtype DATE, containing the tick date.

pvTickUser

[out] Returns a VARIANT, subtype BSTR, containing the user initials of the tick session.

pvAmountDetC

[out] Returns a VARIANT, subtype DOUBLE, containing the tick amount in detail currency.

pvAmountDosC

[out] Returns a VARIANT, subtype DOUBLE, containing the tick amount in dossier currency.

pvTickSysNums

[out] Returns a VARIANT, subtype array of LONG, containing a list of entry system numbers involved in the tick session.

Return value

True if the previous tick info record of the current entry record was found, otherwise false.

Remarks

Use GetLastTickInfo to establish a 'starting point' and retrieve a tick session number, which can be used in subsequent calls to GetPrevTickInfo.
