Dim seedDt As New Chilkat.CkDateTime

// You can set the seed time to any desired value.
// In this example, the seed time is set to the current system date/time.
Dim success As Boolean
success = seedDt.SetFromCurrentSystemTime()

// Generate the 1st ULID in the series.
// (i.e. the current UTC UNIX-time)
Dim utc As Boolean
utc = True
Dim ulid As String
ulid = seedDt.UlidGenerate(utc)
System.DebugLog(ulid)

// Store the ULID in a Chilkat StringBuilder to generate the series.
Dim sbUlid As New Chilkat.StringBuilder
success = sbUlid.Append(ulid)

Dim i As Int32
i = 0
While i < 50
    success = seedDt.UlidIncrement(sbUlid)
    System.DebugLog(sbUlid.GetAsString())
    i = i + 1
