I ran into an interesting situation while attempting to
debug my software. I have written a simple test VI included as “example.vi”
that uses a timed loop and “example 2.vi” which uses a while loop.
I am using LabVIEW 2010 Professional Development System.
I had both the front panel and the block diagram open for
“example.vi”. See “screen 1.jpg”.
I execute”example.vi”. I pressed the calendar icon part
of the time stamp control. The “Set Time and Date” window appeared. I could
select a date without issue. I stopped execution. See “screen 2.jpg”.
I turned on “Highlight Execution” to follow the flow of
the program. I executed”example.vi”. I pressed the calendar icon part of the time
stamp control. The “Set Time and Date” window appeared. When I attempted to
select a date, the “Set Time and Date” window went into the background and I
could not do anything with any of the windows. I did discover that once I
clicked on the windows blue background or opened another program, then I could
go back to the VI and control the VI. See “screen 3.jpg”
I tried this with a while loop, see “example 2.vi” and
the same behavior occurred. See “screen 4.jpg”
