HiI have one project where one Vi (launcher) launch dynamically another vi(Slave). I want to know if there is scripting way to permit Slave to know who launch it.The simplest way, than i have found, is to pass the Launcher reference to the Slave, by one "Define command value" invoke. But my wish, is to avoid this way.

The synchronous Call By Ref treats the invoked VI as a subVI and so the subVI can get caller info from the Call Chain. The Asynchronous Call By Ref treats the invoked VI as a subVI ONLY IF YOU DO FIRE & WAIT. If you do fire & forget, then it is treated as a top-level launch, same as calling the Run VI method.

Solved!

So the answer is no - VI Type Specifiers can't be created dynamically for this purpose - you have to know the connector pane in advance. Correct?

Correct.
