System Exec Problems


Recommended Posts

All,

I have a couple of VIs that I have converted into executables. These executables I am attempting to call from another VI using the System Exec.vi. Unfortunately, the calls work only some of the time on my XP machine.

I get the following error (Error code 2):

Possible reason(s):

LabVIEW: Memory is full.

---

NI-488: Write detected no listeners.

Moreoever, here's a twist. I can place a File Dialog VI on the block diagram and feed the path it produces after I select my executable into the System Exec.vi and it seems to always work. Below I have an example of the two setups I use (the top setup, the File Dialog created path, always works; the bottom setup, constant path, sometimes works):

So I'm left wondering, is there something about the path that I'm feeding System Exec that may cause it some problems?? I really have no idea and would appreciate any help. :headbang:

Thanks.
