Chris It is very obvious by your posting prowess on LAVA and the NI Dev Zone that you are a committed (or should you be committed ) member of the LabVIEW community. I doubt there are very many individuals that haven't taken something away from at least a few of your postings..... Congrats , you deserve it :worship: Dan

Jimi That is the general direction I was thinking of going , but , I wasnt too sure how I was going to do it .... I think I will follow your guidelines and see where I end up... thanks Dan

Jimi Well this is something i have been thinking about for a week or so , i have to interface to several types of temperature controllers and i have been thinking about abstracting the HW as you mention , all i have to do is indicate which controller i want and use dynamic dispatching etc... this would make things a little easier for a couple of other people in the lab who are beginning to do some LV programming , but , have limited or no experience with these controllers and serial communication etc... Dan

Well I am looking into writing an instrument driver using OOP , does anyone have any suggestions as to what type of architecture/pattern would work the best. I think my biggest problem is that in addition to figuring out which design pattern to use as a guide (after looking at it for awhile longer I am currently leaning towards the Specification Pattern along with the Factory Pattern) I also have to figure out how I am going to use the implementation in the real world , any thoughts ???? i know this OOP stuff is new to most everyone , at least in its LV incarnation.... Thanks Dan

I just opned this mess up and the very first thing i said was Holy Crap (actually it wasnt crap i said ) i wouldnt even want to try to take that apart , let alone have a beginner try it.....

I have been sort of following along with this thread and i envy anyone who DID NOT have to live through (read endure) the Disco Era !!!!! very few of the 70's rock bands actually made it through those few years , mainly just the super groups (that were still alive) , since then i can really only think of one band that came out of the post Disco era that i would classify in the same catagory as the 70's super groups and that would be U2.... Dan

Stephen One thing I would like to see is when you right click a class New -> VI that the vi would have the class controls and error clusters already on the FP. Dan

Ok.... attached is my first try at using this OOP stuff.... can some of you look at it and tell me what i am doing wrong , this is based on hardware so you really wont be able to run it , but , you should get the idea.... it still needs lots of work , but , i figured i better stop now before i get too far into it and figure out that its all wrong... dont be too harsh Dan Download File:post-114-1163087862.zip

Past the learning curve , hell i am still stumbling around tryng to FIND the curve

Yes but when you crash do you call the Coast Guard or the Highway Patrol

Bryan i would have to agree with what Ben mentioned about looking at the smaller companies who dont have so many "filters" between you and the job you are after... Dan p.s. i am in the same boat that you are in , my title is Test Enginner and like you i don't have a degree... i have kicked around looking for a new job , but , as of yet i havent been to serious about it , i may be in the spring though... Good Luck

Dont woory in time you WILL be assimilated :-) they even got Picard and Data

Does anyone have a simple OOP implementation they could send me to take a look at .... i have gone through the examples etc... and for whatever reason i dont think i am "getting it".... thanks Dan

in 8.2 it doesnt give you the no can do circle when you drag and drop the decorations from the FP Pallete to the BD , at least it doesnt for me on XP. Dan

No Problem.... glad i could help... Dan

Ok here is everything i have to work with the ROBO's , you will need to change some of the defaults since you have a different lead length. the first 3 things you need to do is INIT, POWER ON, HOME after that you can do whatever you need. these VI's still need some work , but, they got me through what i needed , i actually want to try to re-write them using LabVOOP. if you have any questions feel free to ask. good luck Dan Here are the the protocol manuals that i have in case you or anyone else needs them ....

What version of LV are you using ?? i will send you what i threw together to talk to these things.... Dan

THese cyclinder are really easy to deal with ONCE you figure a few things out , do you have the ROBO Cylinder Serial Communications Protocol document ?? if not i can scan it and send it to you.... Dan

Try something like this Dan Download File:post-114-1161366024.vi

i dont want top resort to that , but , i may have no choice...

Chris yeah i know , it just seems to be getting worse , i try to make my programs as flexible as possible so i dont have to keep editing etc... but it also tends to come back and bite me i the A** at times ah well jus a couple more hours then it's :beer: time.... i think it may be a Guinness night after the past couple of days. Dan

I thought about using the registry but i really dont want to get into that whole mess... i am going to try the checksum for now and TRY to force the burden back onto them.... maybe , just maybe , they will learn if they get burned a few times... luckily these guys dont fit into this category "Nothing is fool-proof for a clever fool." , but , i wish they would jsut stick to letting the program do what it is desinged to do , everything that needs to be done can be done from within the program i wrote.... oh well i guess it could be worse.............

ARRRRRRGHHHHHHHHHHHHHH..... i had a long talk to the techs about modifying these files etc.... and explained to them that it messes things up when these files are played around with , and , guess what , you got it , they still messed around with them... rather than go through all the hassles of changing everything over to hidden and encrypted files i have decided to play games with the techs and put the burden back on them... i am simply going to add a checksum to the end of each file and check it when the file is loaded , if they dont match they will gete a message that the file has been changed and is now corrupt and a new file must be created etc... that way THEY have to go through tthe hoops and not me.... Dan

Ideally i would like to monitor various parameters of the vehicle , at the moment all i need is RPM , but , as soon as we start this i know what will happen and they will want to monitor everything , i have run across this device http://www.drewtech.com/products/cardaqplus.html which looks interesting. it actually will do everything i need i believe , especially with its 6 general purpose analog inputs...
