What is the ndx in COM Collections

[potapczuk]

The index to access objects in COM collections, like InwClashTestsColl, is a variable called ndx. I could not find a reference for this index, tried 0, 1, 2... and also the nwID of the objects, but none worked.

Hi potapczuk,

ndx is just a long for index in a collection. I tried with the code snippet below based on SDK sample AUTO_04, it works well.It means the collection is 1 based.

   ' Run all stored clash test
    m_clash.RunAllTests
   
    Dim oMyTest As InwOclClashTest
    Set oMyTest = m_clash.Tests(1)

Best regards,
