Thanks for the info...I have a better understanding on how to proceed!!!!

Hello All - I am using LV8.6 I am new to LVOOP and I am stuck in a rut trying to solve the following problem. Prelim: Class_A has an instance of Class_X and three instances of Class_B. (Would it be correct to say that Class_A inherits from Class_X and Class_B?) Class_B has an instance of Class_C. (Again...inherits from Class_C?) Problem: 1) When I have to "INIT" Class_B from within Class_A:Init how does each instance of Class_B get its own unique parameters? 2) How does Class_B:Init know to initialize Class_B.lvclass different from Class_B.lvclass 2 different from Class_B.lvclass 3? 3) Can the input lines (blue arrows below) be used to tell the method which parameters to initialize the calling instance?Screen shot of block diagram of Class_A:Init: Thanks for your help.

Thank you Rolf....both for the library and giving me a heads up on the info returned! David

A co-worker found some code on the NI forums site that helps with the problem... Linkup / Linkdown detection; Network cable plugged or unplugged The LLB that is referenced (iptools.llb) ties into a DLL that gives an immediate response to the connection status.

We reset the VME backplane and our XP machine returns that the network connection was lost but the test program continues to report a "56". (We placed a conditional probe to pause for any error greater than "56" and it never stopped.) We then opened the box and yanked the ethernet cable and it took about 10 seconds for the test program to report the "66". It seems the problem is hardware. (Geez I love saying that!) The reset does not necessarily close/destroy the network connection and in the meantime it continues to report the "56". Got to figure out what the difference is between a hardware reset and yanking the ethernet cable.

Hello - Does anyone know of a way to reset a USB device in LV 7.1? Thanks D

THanks Michael...my bad....i don't have a very good understanding of DB's Again Thank You, David

My 'misteak'....I guess it would be a ?foreign key?. I ran into a problem with the method mentioned above last night while trying to create the tables with the DB toolkit. Unfortunately MS Access does not allow tables with more than 255 fields and one of my tables would have 1024 fields. I am looking at different DB's but everyone here has Access...ugh! Can LV DB toolkit tie into other DB's like PostGRE or MySQL? It would be great to be able to search on individual elements of that 1024 table! THanks David

So Data5 from above would become its own table something like this........ Thanks David

howdy - I am using LV7.1 DB tools and I am trying to build a DB of different types of data. Example data format I have no idea how to insert the arrays into their respective field in the table. Would I decompose each 1D array into one long binary value and insert that into the field? Thanks David

Hello - I am setting up an application on a system that will not have a keyboard or mouse. The application will run on its own with minimal user intervention. The user will be able to press a few buttons on the touch screen for limited control. What I need to do is get the application to run immediately when windows starts up...preferably the user will not see any of the Windows screens (ex desktop, task bar, Start button, etc.) When the user presses exit, the app will again shut down and exit windows without the user seeing any of the typical screens. My question: Is there a way to do this? Is what I need to do primarily in Windows or can the LV app do what I need it to do? Does anyone have or know of any examples that I can see/use? Thank You
