I am trying to use a synchronous application (dll) to launch an asyncronous application within Creo 2.0. I want to pass the connection ID to the second application but I am hung up on using the ProEngineerConnectIdGet() and ProEngineerConnectIdExtract() to get the connection id as a string. It is explained in Document - CS129952 but does not go in detail on these two functions. They are breifly mentioned in the user guide (tkuse). When I try to use them in my program, they expect arguements and return either proerror or boolean results. Can anyone give me an example using these functions?
