Error 42 occurred at ni_tagger_lv_Write

[thorholiday]

I am trying to output an IMAQ Image to a network variable. However, when I run the VI I receive the error message "Error 42 occurred at ni_tagger_lv_Write", "Possible reason(s): LabVIEW: Generic error."

Is there some kind of setup I need to perform to get network variables working? All I did was add one to the project and configure it as a variant. As a side note, the program works fine using "single-process" variables as opposed to "network-published" variables.

edit: I am using LabVIEW 8.2.1

Does the error happen as the variable is being deployed or later in your program?

Also, can you create even a simple project that uses network published variables?  Try running the shared variable client -server project found in example finder.  If not, it may be that something (like a firewall) is blocking communication.

I think SV is not very stable in LabVIEW 8.2.1

There is a problem sending certain datatypes to network published Variant Shared Variables.  This problem (Error 42) still exists as of LV 8.6.1.  See my post here:
