executable not working

[User555]

Support website doesn't allow me to fill in support ticket because it gets stuck half way trough so we are forced to open up a forum topic.

Executable is not working on a computer that is not the development computer.

The issue is a not enough memory to complete this operation error.

Development computer labview 2020 professional windows 10.

Target computer labview runtime 2020 windows 10.

The application consists of a single VI wich reads an external sensor via visa to a graph.

Also it would be handy if somebody could tell wat this error code exactly means, because

this vi is so simple it could run on a commodore 64.

Hi 555,

mind to attach that simple VI? (I don't think the C64 will handle the whole VISA stack.)

Are you building an unbounded array in your VI? Are there unhandled VISA errors so that array is growing much faster than usual?

[stevem181]

Did you create an installer that includes the VISA drivers?

See attachement

No, i installed the drivers manually on the target device.

Hi 555,

on your VI:

You should implement a proper statemachine. Much cleaner implementation than stacking loops inside each other…

Do you really need to configure the serial port with each iteration of the inner while loop? I don't think so…

Do you really need to use a polling wait? Would a simple non-polling wait reduce CPU usage?

There are unbounded arrays in the inner loop…

Do you get a "COM port Error" indicated by that LED indicator?

What happens when the FOR does NOT find a suitable COM port? There is no error handling for this case…

Using the WriteMeasurementData ExpressVI, especially when creating an Excel XLSX file, is quite CPU-hogging and slow. Writing to a CSV file would be much easier and faster.

Recommendations:

Improve error handling, additional to the points listed above. You should also show errors in case you want to debug your EXE (right now you set the only error handler to "no dialog")!

Create an installer for your EXE to be sure you include ALL needed drivers.

I've used a proper installer to load all the libraries this did not resolve the issue.

While the VI is poorly "coded", this is only a snipet from a much larger program with state machines,error handling,file i/o etc... This larger program however displays the same error insufficient memory to handle this operation.

The need to write to excel is defined by the customer so using csv is out of the question.

This made me suspect the issue was with the computer itself as it has only 4GB of ram memory. However the application runs without this error on another laptop which is also limited to 4GB ram.

You could try running Windows Task Manager on working and non-working systems.

This would tell you how much memory the program uses (working) and how much is available

on the non-working PC.

In Windows 10 - turn off Background Apps - they can use a lot of resources.
