Example

The following example demonstrates how to add stress definitions to an ALTADataSet object.

VBA

 'Declare a new ALTADataSet object.  
  Dim ADS As New ALTADataSet
 
 'Define 2 stress types with use stress levels = 10 and 25. 
  Call ADS.AddStressDefinition("Stress1",,10)
  Call ADS.AddStressDefinition("Stress2",,25)
 
 'Add failure times for Stress1 = 190 and Stress2 = 235. 
  Call ADS.AddFailure_3(100, 1, 190, 235)
  Call ADS.AddFailure_3(120, 1, 190, 235)
  Call ADS.AddFailure_3(130, 1, 190, 235)

VB.NET
 
 'Declare a new ALTADataSet object.  
  Dim ADS As New ALTADataSet
 
 'Define 2 stress types with use stress levels = 10 and 25. 
  ADS.AddStressDefinition("Stress1",,10)
  ADS.AddStressDefinition("Stress2",,25)

 'Add failure times for Stress1 = 190 and Stress2 = 235. 
  ADS.AddFailure(100, 1, 190, 235)
  ADS.AddFailure(120, 1, 190, 235)
  ADS.AddFailure(130, 1, 190, 235)
