I did indeed mean a chart. I don't want to always log the data because the defined user has a .01% likely hood of wanting the information saved to a CSV. It's a "i might want to some day" feature.

I'm currently doing a VI for a Leak Test machine that may run up to 24 hours. In this time period I'm graphing the collected pressure traces, and that's it. Is there a way to dump the history of the graph to a CSV file? Rather than collecting the data into another array, and then either trashing the array once they start a new test, or saving it to a file if it's involked. It just seems like better memory managment to use the history feature... i guess. Thanks! Jason

Thanks everyone. I'm seeing more and more practical usage for the LabView dev platform. I wish on a previous job I did at the end of last year I would have used it now. For the simple fact it would have saved me a lot of weekends of work trying to get vb 6.0 to interface with a daq to do simple things. We'll see if i can get the company on board for using this platform more often. Now that With our latest project I can prove it's effectiveness, even with my limited skillsets. Thanks everyone!

Thank you, I wasn't able to get back online after i posted the question last night. I did see that it went away after i was able to run it. I really appreciate everyone

Oh.. My.. God. Perfect. No Code = Good Code! So, I've done what you said... i haven't tested much with it, but the first thing I see is an ugly drop shadow... how do i get rid of that business? Thanks!

Hi Everyone. I'm finally just about finished with my labview program. It's been a fun ride. I have a few little user interface things to clean up. Currently my VI has a Tab on it, with 2 Tabs ... Tab 1 is for the "Testing" mode... has the graph and user selects which part to load etc etc... Tab 2 deals with setting up the test conditions, and the general system parameters... both have a ring menu drop down that the user can select which part they want to either (On tab 1) Run, OR (On tab 2) Edit. I would like these two to be linked. It would be nicer if they were the identical control mirrored but what can ya do... for example, if the user is testing part "Part 1" and switches to tab 2 i want it to be part 1, but then decieds to edit part 99, i want part 99 to be selected on the front tab as well.. Make sense?? Thanks for any help you can give. Jason I think I figured it out. I knew i shouldn't be so quick to post this question. It seems like the value property forces the text change as well... So i can just watch each of the rings and if they aren't equal and i can figure out which changed, i can change the other.... Poof!

ah! I was just thinking about it a little too hard I guess... I never really thought about the "first call" control. I am thinking like a c# programmer still where i'm thinking "what code launches first"... where... in this case it doesn't really matter. for a file logistics, I'm probably just going to go to a default.ini file that will hold last part "selected" and a few other details about the software, which will have to load after i load the ring control will all the part names. Then I can use the default file to select the proper 'part' and load the controls with the approperate data. Thanks! Makes more sense now

Thats about what I was thinking, now the trickery... How do i automatically have one of those items selected when the VI loads? Say for example i create a "default" file... this file just keeps track of the last information that the user selected, say "Tiny Part 5". When they reload the VI i want to make sure that Tiny Part 5 is loaded... and all the appropreate things that normally selecting that "Tiny Part 5" from the ring menu would load... I can explain it better though some psuedo code if firstload = true then open default.prt load defaults to controls ring.text = part name end if thanks!

Hi. I just joined! I'm a software engineer up in michigan. We build test equment for mostly the auto/heavy industrial industry. Most of our software is done in C#, or VB. We have been branching out doing LabView Development for some customers as needed. I find it hard to program in labview because i'm not used to it yet, but, i think in general it's making me a better programmer. I'm also heavily interested in automation of anything hacking of anything with batteries or motors, and I love hot rods. So, that's me! Hi

I have finally written my first app in labview. I'm tired, sleepy, hungry, kinda stinky too... but all that aside, i'm almost done, i'm under budget, i'm under in time, and everyone is happy... Almost. there's 1 thing I have left to do, reading though code, i have yet to figure out how. here's the principal idea... i'm open to suggestions. I have a "Front Page" VI were 'everything happens' (Test is prefomed, etc etc.) On another tab I would like to create a area to "create a part". The idea is each part has different parameters. So i need an "Edit" type screen so that a user can create a new part, edit a part, or delete a part. This, isn't too terrible. I can handle most of these operations.. but now what i DO need is on the front panel... I would like to use a Combo Box/ Ring Menu selector, or something to allow the user to select a "part". but, i need to populate this ring menu by the list of file names in a directory (Parts that were created by the user). So, say for example bobby makes 5 parts, which in turn created 5 files. Part_Test1.prt Part_Test2.prt Big_Part3.prt Huge_Part4.prt Tiny_Part5.prt I would like the VI to show in the ring menu selector or combo box "Part Test 1" ... "Tiny Part 5"... just trying to figure out how to envolk something like this to happen when the VI loads. <breath> Thanks!!!!!
