Yen, hey thanks for the lead, looks promising actually...I'll try it on Monday indeed. I didn't think about searching NI's website...doh! Yes also "real" was intended to imply low level network programming. There is no question LabVIEW rocks for high level automation/command/control/etc Rolls Royce style as you say...I just need a unicycle to get a simple packet or 2 out

I'm attempting to test a network protocol analyzer and need to build an app that sends formed and malformed XXX/IP over Ethernet packets. Has anyone generated a generic Layer 1/2 packet using LabVIEW exclusively such that specific values for the Ethernet MAC header and IP header, etc can be all dynamically set or written a LV wrapper around say Winpcap functions? All I see in LabVIEW is the lame Layer 4 TCP/UDP functions. My collegues are attempting to push me away from LabVIEW saying it is too high level of a language for "real" programming. Please help me prove them wrong... Thanks, Billy T

Yup, I'm currently using the picture functions for manipulation just as suggested. Just thought there might be something else I didn't think about. Thanks guys. Billy T :thumbup:

Suppose there is a simple 2-D string array with 2 columns. Column A has values that have an "arrow" pointing to values in column B such that if A = {a, b, a} and B = {b, a, g} then the topology diagram should be displayed below. To make things simpler I am only interested in using "a" as the center such that there will not be values in the columns that don't subscribe to this scheme. Please also notice that a is pointing to g but g is not pointing back to a because there is no pair match (only 1-way). I only want to make custom controls visible/not visible as a complete last resort since the columns can get large. The position of a, b, g and the text inside a string can be visible/not visible however if need be. If anybody has any ideas, you would be my hero. I don't believe LabVIEW is the right tool for this, but please prove me wrong. I am using LabVIEW 7.1 g ^ | | a <--> b Thanks in advance, Billy T
