  1. Pulling the VIs out of an EXE isn't the hard part. In relatively recent versions of LabVIEW you can pull out VIs from an EXE. I think the last version I did this on was 2015. But the VIs are a binary blob with no block diagram, generally no front panel, but can be called as a subVI in the IDE. And with the forward compatible run-time engine that means any LabVIEW 2017 EXE can have its VIs pulled out and ran in 2017 or newer. I haven't tested this but I think it should work. But as others have said, getting the source code out of an EXE is considered impossible.
  2. I don't think making an XControl transparent is difficult. NI recommends setting the Facade VI to be "Window Runs Transparent". Then you can color the 2D picture control to be transparent. If the user chooses a background color other than transparent, then set the background color of the front panel, and set the Facade to not run transparent. If that doesn't work you should be able to draw a rectangle behind the chart the color the user wants. In any case congratulations, it looks like you put a lot of work into this, and I hope the market finds this valuable. I've never tried to se
  3. Wow yeah whole crap congratulations. Everything appears to be native G. It always feels like cheating when I see stuff like this that just is some .Net wrapper under the hood but this is an XControl which I would guess is a 2D picture control. I also like that you can see the settings update as you change them. That being said there are a few things I wish worked better. XControl resizing is one that would be nice so things like Fit to Pane worked. That Circular Chart Designer dialog can't be resized and it is actually too tall for my main monitor. Even the Circular Chart Example VI
  4. Okay for the heck of it here is my interpretation. I read that as OP trying to remove the last few characters from each string in an array. (also I read "few" as 3). Also snippets might not be working so attached is a VI in 2018. Remove Strings Test.vi
  5. Yeah these controllers are quite limited on space. I have a 9132 running wes7 and I was able to install LabVIEW 2018 SP1 development, XNet, DAQmx, and VISA support. After that the drive has very little space left, like 1GB. If possible a better option is like what JKSH said and to create an EXE and an installer, then just install that on the device instead of the full IDE. However debugging things wrong with your application is harder when you don't have a VI to just open and debug. So either option should be possible for you. If you are generating large logs you can put in an SD card, o
  6. There doesn't appear to be a native way to do this, but if you write a VIM for this then you should be able to reuse that on any map type.
  7. LAVA has been known to strip out that meta data in the past. I remember one instance where it was seen when the image wouldn't fully fit on the post and it would do some scaling on the server side. I'll ping Michael but until then I'd recommend attaching the VI.
  8. I'm not a HID device expert (Rolfk maybe?), but there seems to be several DLL wrappers to talk to HID devices, but the best solution is to use NI-VISA and talk to it over USB Raw. For this you'll need to make your own INF driver using the NI-VISA Driver Wizard (should be installed with NI-VISA). Then install that driver for your device instead of the one from Microsoft (Device Manager). For this in Windows 8 and newer you'll need to disable driver verification. Then the device shows up in MAX, and the Help >> Find Examples and searching VISA Raw will show some examples. http://w
  9. It is open source. It is licensed under BSD, which in layman's terms means you can use it for personal or commercial use, and various attributes must remain in the source, and you can't sue the author (I am not a lawyer). I think the installed location is <user.lib>\_LAVA\VariantProbe
  10. Here is a quick and dirty edit. It allows for column separators to be moved, but I noticed that on resize it will set the column widths. So this means if you manually move the columns, and then resize the control it may change the columns in an unexpected way. But at that point you can manually move the separators again. I only have 2017 and 2018 so this is for 2017 and newer now. Variant_Probe-2.4.3-0.ogp
  11. There's a little bit of Rube Goldberg action going on here, but I think I follow what you are trying to do. I'd suggest precalculating what all the values are and put that in a subVI. Then call that subVI and index out the current step that you are on keeping track of it in something like a while loop and a shift register. Attached is a simple example. Have you taken any free LabVIEW training online? Here is some on the LabVIEW Wiki. Ramp Pattern.zip
  12. Oh and lets not forget that some cRIOs now support DAQmx so programming the FPGA part is even more optional. https://knowledge.ni.com/KnowledgeArticleDetails?id=kA00Z0000019PUNSA2&l=en-US Some times I find myself changing what things I want to be done where. I might start with an idea that certain tasks will be on RT and others on the Windows host, but as time goes on I realize my decision might not have been ideal. I guess what I'm saying is whatever you do, make sure you let your design be flexible enough, that a total rewrite isn't needed if some part of your software needs
  13. Oh yeah I forgot I used to do this. I'd download things and just throw them into a sandbox folder where I could play around with stuff people posted and see if I can mine any reuse nuggets out of. I'd try to make a text file with a link to where I found it online, but searching the name of the VI in google was usually enough to find where it was being discussed. Still this is less about what OP is asking, and more just myself trying to find and use useful tools.
  14. We generally don't close threads on LAVA, even things like this can be useful to others...assuming you have a solution that is worth sharing so someone in a similar situation can find what you did.
  15. For the most part I just use Google, and the fragments of memory I have. Someone will post something and I'll be like "That sounds familiar, did I help answer a similar question once?" and I'll search "(topic idea) hooovahh site:lavag.org". Beyond that I do have a list of commonly asked questions that I bookmark. Chrome settings are synced if you are logged in so I have a few folders with common links to various threads that I add to from time to time. Sorry I don't have some super magical RSS tool.
  16. I think this is exposing one of the issues NI had with XNodes. One reason I was told by R&D that XNode development had slowed and halted, was due to the fact that XNodes don't work well inside classes, or more specifically they don't work well in libraries. I couldn't pin point the issue exactly, but it seemed that opening a library would lock the XNode, and opening the XNode would lock the library. I found some working solutions that were all terrible but I just couldn't get the IDE to work nicely and I suspect an XNode in an XNode has the same issue and I think name space was partly t
  17. That's good to hear, I guess I don't need to use this meme.
  18. Thanks for the update. There's lots of reasons to see less activity on the forums. Life happens, people get stretched, people get bored, people change careers, etc. I personally try not to take your activity, or others like you, for granted. And any contribution you make to the community is always appreciated.
  19. You've probably already seen it, but there was an announcement made.
  20. That is odd. I've been getting the same warnings for a long time now but my EXEs are build just fine and work as expected after hitting Ignore a few times.
  21. I'd disable PC sleeping and hibernation, disable power management, or set it to performance, and make sure USB ports aren't being put to sleep for whatever reason. Does this happen on all USB ports? Is this through a hub? Beyond that do you have any odd software running that might be scanning for USB devices? Some employers install software to lock down the PC and it could be interacting with it in a weird way.
  22. I'm pretty sure the item selection in that tree means nothing, and setting it to -1 and disabling it might be the best option so not to confuse the user. All that matters is what items are selected with the checkbox. And even the checkbox acts like a radio button where only one item can be selected at a time. You can of course have multiple controls in a QControl, but it will only inherit from one class.
  23. As far as I know it is still happening. As usual we are a bit behind in the planning but as of right now it is still on, details to be posted when we have them.
  24. I asked a similar question a while ago and Dr. Powell chimed in with what he believes it means. EDIT: Oh and a thread where AQ explains that having a clone reference doesn't keep the main VI from leaving memory. If it does it will close the clone references that you still have a handle on and can cause crashy.
  25. I just tried with another command that is in the system folder which is "dir" here is the command line string value I used: cmd /c dir "C:\Example Project" /w This was with the Working Directory being empty.
