I was looking for a way to simply pass status messages from anywhere in my application to a log file and/or a status message box on my user interface without having to pass a queue reference or event reference everywhere. I wanted something like the good old printf() command that I could litter throughout my application. I also wanted something that didn't take much place on the block diagram. This is what I came up with. This VI sends the message string along with a time stamp and the call-chain to listeners of the "stdout" event (only if the specified verbose level less than or equal to the globally set verbose level). The message received by the stdout event handler is an instance of the "LV_Printf Msg" class. The data is available though property nodes or it can be flattened to a string through the dynamically dispatched "Receive Message" method. You can create a child of this class and override the "Receive Message" method to format the message differently. Please try it out and let me know your thoughts.
