Greetings, Due to limited licenses, I cannot install Labview on all the machines I would like. Consequently, the development and deploying are often on separate computers. Does anyone know of a viewer which would open a vi and allowing browsing of the front panel and code? The viewer would be like a '3-d model' viewer where you can only view the model and manipulate it, but not alter. If no, does Labview support introspection and reflection like java -> build Labview exe that encapsulates the vi? Thanks for your time. JMA

Greetings, The MIXED SIGNAL PLOT has a property node which can control the height and width of the plot area. How do you specify the plot area (size) of each plot within the mixed signal plot? Any thoughts would be appreciated. LV 8.0 Cheers, JMA

A few approaches come to mind on how to accomplish sending a signal from java to trigger a DAQmx device: 1) Create an executable of your Labview code. Use a system call from your java code (assuming it's an not an applet) to launch the executable (trivial). This is the simplest, but is limited by your task (passing data, etc.). 2) Wrap your java code using the JNI interface. Have your Labview code make a call to your java application and check if the task should trigger (CIN node? dll, or similar). If you like puzzles, this is a fun one to try. If you are comfortable using java and C/C++, this would work. 3) If you are deploying this to a desktop, does the computer have multiple serial ports, parallel ports, or USB ports? If yes, perhaps you can use the javax.comm package and loop two ports together. Setup your Labview code to listen for a specific message and then trigger the event. If this works, it would be trivial to pass data back and forth between java and Labview. This is by no means an elegant solution, but it will work reliably and is fairly trivial. I've used the javax.comm package with 115200 baud with good success. Without more specific data on your particular application, these are all the suggestions I have. Cheers JMA
