Customer.UnlockRecNum(hRecNumCurrent)
Syntax
<Result> = <Source>.UnlockRecNum([<Record number>])
<Result>: Boolean
  • True if the record was unlocked,

<Source>: Type corresponding to the specified source
Name of the data file used.
<Record number>: Optional integer
Number of the record to unlock.
If this number is not specified (or is equal to 0 or to the hCurrentRecNum constant), <Source>.UnlockRecNum will read the current record.
Native Connectors (Native Accesses) <Source>.UnlockRecNum unlocks the current record only. You cannot specify a record number other than the current one (to specify the current record number, use the hRecNumCurrent constant).
Remarks
<Source>.UnlockRecNum has no effect if:
  • The data file is in single-user mode (see <Source>.Mode).
  • The record is not locked.
