Hello, I've just upgraded twice, from LabVIEW 7.0 to 8.0 and finally
to 8.2.1, installing the PDA module for 8.2.1 as well (I didn't use
the PDA before), so I have two fairly basic questions regarding
programming for the PDA.
My PDA is an HP iPAQ HX2790 running Pocket PC 2003.
I have written a C program in LabWindows/CVI that writes graph data to
a text file, and I call this via DLL (created in eVC++) from LabVIEW,
with which I've also written a VI that reads the graph data from the
file.
Both of these VIs work separately (I can write to the text file in one
VI and read in the other), but when I try to combine their
functionality by placing the ReadFromTextFile VI's graph data as an
output on the connector pane and including it as a SubVI within
WriteToTextFile, I get the following error: "App failed. Error code
501103025. Event queue dealocked"
What is it about the subVI that might cause the execution to lock
up?
My second question is simpler, although it has more to do with PDA
interface than LabVIEW. The text files to which I write on the PDA
appear in the My Device folder (the highest level, default folder). I
would like my C program to write to the My Documents folder instead,
but adding "\\My Documents\\" to the C string for file path doesn't
work (it still puts everything in the My Device folder (labeled as
seen from file Explorer). Single backslashes yields the same result.
What is the syntax for PDA folder pathnames?
