User defined types,refnums,and program autoupdating

[mishklyar]

Hello all the Masters,

   I am working now on a large program.And tried to do the next thing: to put  controls and indicators at the cluster,

make it "strict type definition",and pass a reference to this cluster to the sub vi's.The main point is,that the sub vi's update

the values of this cluster too.Here I come to the point : I wanted that if would be easy to add/remove controls to/from the cluster.

   The solution that I "wired" is attached.It uses  .xml file for indication,if the datatype was updated,and if yes,promts user to choose

which variable he wants to update.

  I would like to know your opinion about this "trick".

 Thanks,

Michael .

I read your post and looked at your VIs, but I can't quite figure out what you're trying to do. Are you trying to add/remove items to a cluster at run-time? Why? You also said "to put  controls and indicators at the cluster," - you can't mix controls and indicators in the same cluster. Please provide a better explanation of what you're trying to accomplish.

Sorry about been not clear: no indicators,just controls at cluster.

The main goal was to do the whole program easy to make changes,such as changing datatypes.Now,the vi's that posted performs a check,

if there were a change at the datatype,if yes,the vi promts the programmer what variables he wants to pass now to be updated and saves the selection.

      I am shure that I am not the first one who thinked about it,just wanted to hear opnion of people who more experienced than me.

  Thanks for reply.
