create file in dll (LV version conflict)

[mitulatbati]

Hey all,

I want to do a very simple thing in a VI, which is build in a dll. The VI should create a file.

It works if I compile the dll in LV7.1, and then call the dll in LV7.1. If I call it from LV8.6, a fatal error is generated, and LV dies. If I compile the dll in LV8.6, the same happens if I call the function in LV7.1.

Where is the failure? The atttached screenshot is the VI in LV8.6.

Hi,

is there an error message or an error code?

If I understand you right, the situation is as follows:

DLL built with LV 7.1 ---> it works on LV 7.1

DLL built with LV 7.1 ---> it doesn't work on LV 8.6

DLL built with LV 8.6 ---> it works on LV 8.6

Is that right?

Hi Raphi,

yes, it's right. As an example I attach a screenshot of the error, when I call the 8.6 dll in 7.1. It's in German, but MemoryManager.ccp Line 437 should be undersotood 🙂

Hi,

thanks for the error message.

I got the information that you are already in contact with the National-Instruments Support. They will find a solution for that problem.
