  1. I never use the wizard. I used the online documentation and wrote VIs by hand.
  2. The "pretty print" includes a length check, and keeps small objects compact. You can see it in the code; it's 40 characters or less, I think. This was added to improve the readability of arrays of small objects. Unfortunately, "pretty" is subjective, and it is hard to come up with simple rules that work for all possible input JSON.
  3. I haven't (yet) implemented an "any depth" wildcard character, but if you know how many levels down the item is, you can use wildcards for each level: $.*.*.*.*.NID_PACKET
  4. Did you try a non-Messenger Library TCP example to see if it has the same issue? Another test would be to launch a basic actor (not the TCP communication ones) and see if that causes the same disconnect (if so it could by the ACBR stuff). Unfortunately I'm not on 2019 yet, so can't look into it.
  5. That node starts the TCP Listener; can you try some simple example code that creates a TCP listener and see if it has the same issue? Note: if you change the "TCP Listener" Actor to non-reentrant and to open front panel, I think you can debug it on RT.
  6. Ah, so you need to get DLLs compiled for ARM. I think I just got those DLLs from the postgres install. If you have postgres on the ARM, look for those DLLs and replace the current versions with them.
  7. Try your exe on a regular Windows 10 computer that does NOT have Postgres installed. This is to tell if it is a missing dll in the build, or something about Windows IoT that is the problem.
  8. If those DLLs are there then my only idea is that perhaps there is an additional dll that is needed, one installed on your Dev machine but missing on the deployed machine. What is the exact error message?
  9. If this is an EXE, see if libpq.dll and other dlls are included with the EXE, in its "data" folder. This should happen automatically (because the dlls are part of the PQ class), but I've seen this fail before. If they aren't there try using "Always Include" to include them. The data folder should look like this:
  10. I'll have a look when I get a chance. You might just need to install 32bit postgres, just to get the pq dll from it.
  11. Sure. I suspect smithd already has a backsaved version, so you might ask him.
  12. Substitute more intuitive terms then. My point is that the OP is criticising "aggressively promoted frameworks", DQMH I guess, as if the point of such things is raw indicator update speed.
  13. A note on "Messaging": A Messaging system is one where different bits of information "messages" come through and are handled one-by-one at the same point. Because different messages are mixed together, the communication cannot be lossy. Even if you have no messages that represent must-not-be-missed commands, you will still have the problem of missing the latest update of an indicator, because of an update to a different indicator. This is different from the case of using multiple separate (possibly lossy) communication methods to update independant indicators (often, this kind of system uses the terminology of "tags"). Because they are separate, the latest value of each "tag" is never lost. But this is not "messaging". Considerations of whether to use "messaging" or "tags" is another conversation.
