VB API Examples / models / ReplaceInstance.asm

hi all

      i'm trying to learn vb api ,but the solid function 'replace' can not work, not only the mechanism ,but also the models.

      the model 'ReplaceInstance.asm' can not find component '#5 (PHILLIPS7_8<BOLT>)', but when i retrieve it, only the part 'bolt.prt' can be selected and when i click OK, it shows that this part is unfit.

      if anyone has an corrected 'ReplaceInstance.asm', inform me pleace.

      Or if anyone could teach me how to use 'pfcAssembliesExamples.replaceInstance(asyncConnection.Session, txtModel.Text, txtOld.Text, txtNew.Text)', please ...

      i have no idea about the three arguements of modle name or instance name, which component that the arguments stand for?

     and  my email:   jeremy.quaintor@gmail.com
