    [CR] SQLite Library

    I want to clarify that as far as I know there's no standard way to store an image in a SQLite database. That is, @Gepponline, your question has nothing to do with SQLite much less this toolkit. As far as we know, SQLite Administrator uses a proprietary binary format for storing the images as blobs. You should really go to that community to determine what that format is. Unfortunately, that project looks like it was abandoned with no source code available so you might just be out of luck.

    X-Control : Data Changed? Event not happening

    The "Data Changed?" property of the action output doesn't trigger the data change event. You have to do that manually. The data change event is triggered when the control is accessed as an indicator, property node, local, etc.

    LabVIEW snippet PNGs are being sanitized

    I can't get snippets working. Did they die in the recent site update? Example: I use the editor that shows up at the bottom of the thread and the "choose files" link. Using Chrome.

    [CR] SQLite Library

    I suggest you break your question down into parts as different threads and forums will be able to answer each part better. It looks like your SQLite stuff is correct and your issue is just flattening and unflattening so the machine vision forum might be a better place to ask for help. In the interim, here's one way to do your flatten unflatten using the IMAQ toolkit.

    [CR] SQLite Library

    The attached code shows how SQLite will interpret various types into an integer. It makes me a little nervous that there's no warnings or other way to determine that a value might not match what was requested. I guess I could check every value for its column type. Is there an easier way that I'm missing?
  6. I believe they are in the reference array according to the tab order You either have to know the names in advance or carry their names with their values.

    Making Coerce To Type a little safer

    No, it will break if you try and convert a U8 into U16 so it's a little conservative in that manner. The programmer would be expected to do the U8 to U16 upstream to "get rid of the broken arrow". It would be really cool if there was a way to allow all the "safe cooerces".

    Making Coerce To Type a little safer

    Coerce to type is useful for getting nontypedeffed data into a typedef form but there's a small problem of type safety. For example, if you try and coerce an I32 to a U8, the value will silently wrap without even so much as a coercion dot. But in recent versions of LV, we have something to ensure a little safety— "Assert Structural Type Match" And fortunately, for this use case, it's not so sensitive as to disallow typedeffed data from matching it's plain counterpart so we can use it to enforce a runtime error if someone wires an I32 up. And, to make this new function more convenient, you can wrap it up in a VIM.

    cRIO voltage from NI 9264 is wrong

    No, by current spec I mean: By "how are you connecting", I meant connecting to the analog side of the module. For example do you have one of these: http://sine.ni.com/nips/cds/view/p/lang/en/nid/210164 I see that you have the module setup for differential, that's a little more tricky right? Can you try single ended? maybe with a battery or a potentiometer. Otherwise you have to watch out for things like common mode voltages and such.

    Tree Data Structures In LabVIEW

    Many people use variant attributes for trees. I'm a little curious about your time sensitive use cases, it almost sounds like you want a sorted list instead of a tree which, I think there are some examples of using maleables in 2018. I think being able to use variants in the in place structure may have opened some doors: This is pre 2012 but it's a implementation of some data structures using DVRs and OOP

    cRIO voltage from NI 9264 is wrong

    I assume you've configured the 9205 for single ended vs differential correctly? Are you within the current spec of the 9264? How are you connecting the modules? A cable or one of NI's breakout boards? Try and simplify things as much as possible. For example, use a battery as a voltage source directly to the input and disconnect the outputs to rule out loading issues.

    NI Driver Critical Vunerablity

    Does this only affect users that get updates from the repositories? because that seems like a fairly small minority.
