You can also change the visibility of a control or an indicator depending upon other button or knob. One can change the color of a slide bar depending upon its present value using property nodes. What does the word programmatically means here? This means changing the properties of the objects present on the front panel using the objects already present on the front panel as you will see in detail in the example provide in the explanation section. With the help of property nodes you are allowed to programmatically change the color position visibility and display of almost all the controls and indicators on front panel during runtime. You can change or control the properties of front panel objects programmatically by using property nodes. In LabView property nodes are used to make your program powerful and fun to work with.

You hit a nerve: this is one standing issue I have no patience for and I am a very patient man. To be fair, they have made fantastic advances, and it's not like other IDEs/languages are all rainbows and such.Īnyways, sorry for the rant. It's the development environment I care more and more about, and I'm not sure NI is winning that battle. I may be more proficient in LabVIEW now, but that's just because it's been the tool du jour for the last few years. I'm at the point in my career where a language is frankly just the grammar I use to get my ideas down. I'm a firm believer in LabVIEW for large application development, but shenanigans like this make it a hard sell at times. I have big projects which are fine in LabVIEW, but I also have ones like this. I *hate* this solution but I've literally invested hundreds of hours into trying to make LabVIEW work right and have frankly given up.
#Labview 2013 changes code
Major libraries are pushed not through source code control but VIPM repository updates. To allow multiple developers each library is "owned" by a person and never worked on in tandem. I've lost the ability to develop on multiple machines for that project because it's just impossible to untangle the legitimate changes from the the other ones.
#Labview 2013 changes update
Commit the changes though and update your source on another machine and you're SOL: dozens of VIs (not ctl or lvclass files) give the dreaded and oh-so-helpful "Type definition modified" message.
#Labview 2013 changes full
Only difference with my problem is once saved on a computer it is good- the full project can be opened/closed as many times as you like without anything appearing dirty. The project has seen major development bouts in versions 2009, 2011, and now 2013, but also went through the intermediate versions and some of the code is legacy which pre-dates 2009. I've been dealing with this for years on one of our projects. Oh, and 'mass compile' did not fix this issue. I have all code set to "separate compiled code from source file". By editing them I forced something to permanently alter them into LV2013 type defs and that fixed the issue.Īnyone else see something similar to this? So, my theory is when LabVIEW converts from LV2012 to LV2013, it changes the type def files and triggers the need to save the calling VIs but for some reason that change is not saved in the type defs so each time I open them, they again convert from LV2012 to LV2013 and re-trigger the change. I then repeated this process with every type def in the project and saved (individually) each calling VI.įinally, now when I open the project there are no VIs that want to be saved. I closed and reopened the project and now the number of VIs wanting to be saved was smaller (and the one I 'fixed' was not among them). I nudged the control by one pixel and saved the type def. (Oh, and of course it never says WHICH type def changed!)Īfter fighting this for weeks I finally opened the project and then opened one of the types defs used in one of the files wanting to be saved. There seems to be no way to get them to save the change once and for all. I go ahead and save them then close the project and reopen it. Now every time I open the project, a bunch of VIs want to be saved because they claim a type def was updated. In a large project built in LV2012 and then loaded into LV2013, I recompiled and saved all files. I am not sure I can totally prove this but here is what I have seen:
