TestStand 4.0 custom step type, NI example error

[CarloGu]

Hi, I am evaluating TestStand 4.0.  

Trying to run the step type example supplied by NI, but I have found an error, unfortunately I am not able to understand and fix.

Running the example all TS_ExprCtrl_Create(..) functions called by CreateExpressionControls(..) return errors. Here below a fragment of the CVI 8.0 Debug Output Window

May anyone help me ?

NON-FATAL RUN-TIME ERROR:   "c:\...\StepTypes\CVI\HP34401a\HP34401aStepType.c", line 356, col 5, thread id 0x00000B98:   Library function error (return value == -143 [0xffffff71]). ActiveX control error

Hi,

Have you rebuilt the step type within CVI 8.0 or are you running the example sequence file from TestStand as supplied by the installation of TestStand. If the later you my need to get a compatible RTE for CVI.

Hi Ray,

What I have described happens in both cases. with  the  original files  supplied by NI and with recompiled CVI 8.0.

Notice: In the recompiled version I had a work around to exclude the instrument see HP34401a_xxxx(..) functions, as you can see in the HP34401aStepType.c attached file.

Hi,

I have tried the example in TS4.0. I initially had to download and install the HP34401a driver from the NI website.

After that the example run fine. I don't have any instrument attached so it was running in simulation mode for the IVI driver.

Also, I can open the edit panels as well.
