Remarks
This Node provides a powerful way to engage with existing or legacy systems and supports tasks ranging from opening documents, executing simple commands (eg. document print) and engagement with Windows console applications (eg. via StdIn/StdOut and command-line arguments).
Ensure that the appropriate DropPoint is used. It may be necessary to use a 32bit DropPoint to launch and engage with 32bit processes.
There are two basic techniques. When UseShellExecute is set to true, the process is launched and the Node returns asynchronously (ie. fire and forget). When UseShellExecute is set to false with WaitForExit set to true, a process can be engaged via StdIn and StdOut.
