Im getting Error 1055 after trying to fix a memory leak

[JSMitchell]

Hi all,

I was trying to fix the obvious memory leak from figure one which came from creating objects in the while loop however when I tried the fix in figure two I am now getting error 1055 object reference is invalid... can anyone point out what could fix this? I've also tried using shift registers as shown in figure three but this gave the same error 1055 as figure two. Any help would be massively appreciated.

figure one: memory leak creating infinite objects

 figure two: error 1055figure three: shift registers

show your code, especially subvI in loop.
In figure 2 you've closed all references. Why?
I think you do the same in your subVI

Couple things, first off the sequence structure is unnecessary- think dataflow.

Second, Artem is right, the object reference is invalid because you close the object reference after its first use. Without code to test it's hard to say but putting Close Reference outside of the while loop, only used after you're done, might fix things.

Hi,

I tried the close reference as an attempt to a solution which I found after some Googling.

I didn't get the 1055 error before trying to move the create object parts outside the loop.

Honestly, I'm not really sure at this point as I'm new to using objects in LabVIEW.

The subVI. the other SubVI in this one is just the rotate and translation included in LabVIEW Robotics

Again, we cannot debug pictures. please attach the actual VI.

(Also be careful with naming. You are talking about "3D objects". The term "object" is typically used for something else)

Sorry, this folder has the entire project - "3D picture test" is the current trial solution and backup five is the version with the memory leak.

I didn't get error/memory leak in 3D picture test.
You only need timeout in loop.

What would be the logic behind this? What is a "timeout" and where?

(A delay would simply push a memory leak to a later time, without fixing the underlying issue.)
