A picture would be very helpful in demonstrating what you are having
trouble with.
Lacking that, I will guess.
VI Properties >>> Windows Size
lets you define the minimum size of a FP window.
Well that's my guess!

hysical memory is called for.
So...
Start by using "Task Manager >>> Performance" to see what your memory
usage is durring run time. If possible, upgrade your memory so you are
using physical memory only.
Well I realize that I have been rambling a bit so I should stop here.
So...
You probably need more physical memory.

Yes sir!
>From what I have read about LV 7.X and hyperthreading, two of these
re-entrant sub-VI's can be executing simultaneously without having to
resort to dual-proccessors.
Ben
If the sub-VI is CPU intensive,
and
you do not want one call of the sub-VI to delay another call to the
sub-VI
Then re-entrancy is very useful.
Ben
each occurence of the sub-VI in a diagram.
Also, if your sub-VI use larege amounts of memory the use will be
duplicated between each instance.
Ben
And yet another idea
Use a tab control or a set of tab controls.
You can drive a single tab control with 20 tabs for 20 views,
or
use 20 single page tab controls.
Ben

OK.
One more wild guess.
This application does not use VISA by any chances, does it? I have
seen lock issues when opening FP that have a VISA resource control on
the FP. Just a guess.
I will watch for your post in the AM.

Could you post the "stripped down" version?
Maybe I or others can spot something.

Another approach would use normal constants on the diagram that feed

If you liked his answer, give him some stars!

Not bad for a "first Project" type question.
There is always the option of wrapping all of the init code in a
single frame seq structure "out front" that uses data flow to force it
to execute first.
Ben
Like " I said some of our "best". "

l work provided your sub-VI's do
not have any trouble being called by different "main" VI's.
If the simple "re-naming" works for you good!
If not, I suggest you post a new question and include a copy of your

it as "My app.ini" (where "My app.exe" is the name of your exe),
LV will serve the configured pages.
If memory serves me correctly, you also have to make sure the web
functions are included in the exe when you do your build.

Good job!

There is another example near that one that shows how to draw a
pie-chart.
Parts of that example can be used to add your over-lay yur grid (i.e.
do not fill).

On this web-site under examples there is an example that demonstrates
how to rotate an image in a picture control.
Throw some grid line on top of that and you are there.

The small while loop allows each state to have a unique set of
transitions. If it was outside the individual states (as you
suggested) the transition would have to be shared.
I hope this answer along with Sacha's answer is valualbe to someone.

latest and greatest screen drivers or by changing the hardware
acceleration settings for the display. In my experience LV has always
played the "graphic update game" correctly. It the hardware/drivers
that are not keeping up.

Is there any possibility to get this app loaded and saved as at least
LV 6.0?
At the current rate, I am running the risk of wasting alot of your
time before I can be sure if I can even help!
Short of that, I am concerned about race conditions due the extensive
use of globals.
Ben
Instead of clciking once to make the FP active and then clicking the
second time to actuate the switch, one click makes the FP active AND
actautes the switch.
Add
DropThroughClicks=True
to the ini file.

Thank you Robert!

Hi Bill,
Have you concidered using the microphone input?
That will let you do analog in on most PCs.
Still trying to help you get started.
Ben
Then review all of the code and start enclosing code inside single
frame seq structures. Make sure data flow dicates order.
Of particular concern is WHEN the stop global is written. Make sure it
does not get read to early!
Ben
"I didn't write it...just trying to fix it. ;)"

Not the globals themselves but how they are used.
I never use globals I devlop myself.
I have worked with them in others code.
I suspect a race condition that is a result of over using globals.
If I could look at the entire app, I may be able to spot the race
condition.

Setting

OK,
How about an image of how these sub-VI are being called.
The extensive use of Globals makes me nervous but I can not spot
anything solid that would cause me to suspect a race condition.
Images of these VI's being called will shut me up.

this time is to check the length of
the string in the accumulator when it is in the hang condition.
This would also mean that you could "un-hang" the loop by pulling the
cable while hung.
