The software Icon is still on taskbar , after I close the software in 64-bit Windows 7.

I suspect the CD would perform a bit better in a benchmark, Especially if the UI thread is heavilly loaded.  Although, most UI activity should be done after cleanup Might make an interesting diversion and a good use for Precision Timer.vi

You must be pretty bored for the end of the day on a Friday.  I would almost guarantee that the CD will perform better because it makes the decision at compile time instead of run time.

Oh I agree.... Just sometimes.... "unexpected results" can occur so, I'm not putting money down without checking it out. 

almost guarantee reminds me of "a little bit pregnant"

Yes, I build an exe file.

[StevenInToronto]

Please help me to check if it is correct. I never user APP.Kind before.

Thanks a lot.

<NOTE>Should have updated web page before posting...</NOTE>

There are quite a few possibilities.  Your code has many race conditions since it uses local variables to pass data around between loops.  This is always a bad idea.  Local variables should only be used to update or initialize UI values.  Values used to control the program should be in wires (preferred), data value references, or  functional global variables (also called shift register or LabVIEW 2 globals).

Your program is overly complex.  For example:

1. The second loop from the top is unnecessary.  You could remove the queue and simply write the local directly from the event structure (assuming you kept the local variables - don't).
2. The delay in the event structure loop does nothing, since the event structure is already slowing down the loop.
3. Unless you want a current time display, the top loop is unecessary.  You would be better off creating a subVI which generated your time/date strings and calling it when needed.
4. Your bottom loop lacks a shift register with wire which holds state information (e.g. "event element").  This results in your passing a lot of info on local variables.

To do the fastest fix for this code, I would add a shift register to the bottom loop which includes all your state information and use this to replace all the calls to local variables.  Change the bottom loop from a simple state machine to a queue driven task handler.  Use the event structure to send messages to the bottom loop using the queue.  Delete the other two loops - their functionality can be folded into the new bottom loop.

If you are unfamiliar with this master/slave architecture, check out the examples that ship with LabVIEW and that exist on the NI website.

When you posted your code, you did not post the subVIs.  In the future do a save with dependencies and zip the entire set of VIs to post.

Good luck!

Like I said... refactor the code..  😉

To learn more about LabVIEW, I suggest you try looking at some of these tutorials.

[StevenInToronto]

Thanks. I will refactor the code.

But right now, I need to know how to use app.kind to close me application and/or front panel. Please take a look the attachments. Is it correct?

Thanks.

Steven

[Ray.R]

No.. in your case, you are simply closing the reference to the application.

I'll draw an example.
