LabVIEW prompts to save the vi when closing the reference

In our application, we - Open vi reference - finding its execution state - closing the vi reference. While closing, LV prompts to save the vi, how to avoid it. I can see option to enable LV prompt, but no option to skip it. We use 0x20 for now to avoid the loading dialog.
We appreciate your input
Thanks

Solved!
Go to Solution.

I have seen this in the past with scripting VIs and I tried to resolve it but couldn't. So my solution was just to supress the dialog temporarily. Darren posted over on LAVA a VI that does this.

I lose the connection when closing the CMD

Hi guys,
I have configured a standalone listener as following:
C:\Program Files (x86)\Java\jre6\bin> java -Dapex.home=D:\list -Dapex.images=C:\images -jar D:\apex.war
Afterward,
If I close the CMD, I will lose the connection, and I have to reconfigure it again.
If I open APEX locally , I mean by using the shortcut "Get Started With Oracle Database 11g Express Edition" , Then I will lose the connection that uses the default port of the listener, that is 8080.
After I configured the listener I got this message on the CMD

Hi,
I'm not sure I got your question right, but I'll try to find some solution anyway.
If I close the CMD, I will lose the connection, and I have to reconfigure it again.That's what happens when a shell is terminated - all associated processes will stop as well. However, if you have a apex-config.xml in your apex.home you shouldn't need to configure your APEX Listener each time your start it, but it would reuse an existing configuration.
If I open APEX locally , I mean by using the shortcut "Get Started With Oracle Database 11g Express Edition" , Then I will lose the connection that uses the default port of the listener, that is 8080.Now, if you have XE running on the same (local) machine as you have your APEX Listener running in standalone mode, you probably have a port conflict: By default, both APEX Listener in standalone mode and the Embedded PL/SQL Gateway (EPG) use port 8080. The EPG is activated as web server for APEX in XE after a fresh installation, the APEX Listener would be an alternative in that case. You can either stop the EPG, or reconfigure any of the two web servers to use a different port, if you want to run them parallel.
To change the port used by the APEX Listener in standalone mode, you simply add another parameter to the startup: -Dapex.port=8888 and you're done.
To change the port used by the EPG, connect as sys and run the following
EXEC DBMS_XDB.SETHTTPPORT(8888);
COMMIT;If you want to disable the EPG, simply set the port to *0* .
After I configured the listener I got this message on the CMDThat's what it should look like.
No, since your topic is "lose the connection when closing the CMD", I assume you search for an alternative. You could run the APEX Listener as a Windows service, even in standalone mode. To do this, you create a batch file, e.g.
%JAVA_HOME%\java -Dapex.home=D:\oracle\APEX_Listener\_home -Dapex.images=D:\oracle\apex_4_0_2\images -Dapex.port=8888 -jar D:\oracle\APEX_Listener\apex_listener.1.1.2.131.15.23\apex.war >>D:\oracle\APEX_Listener\apex_listener.1.1.2.131.15.23\my_apex_listener.log 2>&1Note that you have to set JAVA_HOME as system property or replace the call with the absolute path to your JDK or make sure the JDK is in your PATH variable.
Of course, you can and should change the other directories as well to fit to your system.
Next, create a Windows service, e.g. using [url https://iain.cx/src/nssm/]NSSM (free) or [url http://support.microsoft.com/kb/137890]SRVANY (MS, non-free), that starts your batch as a windows service.
The command for creating that service using NSSM could look as follows
nssm install APEX_Listener D:\oracle\APEX_Listener\apex_listener.1.1.2.131.15.23\startup.cmdYou can edit the service properties afterwards, e.g. change the start mode from "Automatic" to "On Demand".
I hope this answers your question. If not, please point me into the right direction.

How do I configure Firefox 4.01 to save all tabs when closing the browser?

In the previous version 3.x.y of Firefox, when I closed the browser, it asked me if I wanted to save my open pages / tabs before closing. When I subsequently opened the browser again, it reloaded all the previously open tabs / pages. In version 4.01, before closing the browser warns me that I am closing multiple tabs but when I restart the browser again, it does not load the previously open tabs. How do I configure the browser to behave like the old 3.x.y version, i.e. neatly saving all the open tabs and loading these again when opening restarting the browser?

Hi TonyE, this was a very useful reply. The first part of your answer had already been posted by someone else. Your answer in particular shows the nitty gritty detail of how to automate it. I had searched in the options already but had not found step 3 above yet. But I have found it now and have changed it from "Home page" to "Show my windows and tabs from last time".
Thanks a lot for letting me know this solution and making me aware of the drop down list.

Tecra M7 : new bios shutdowns the digitizer when closing the lid.

it took me a moment to find the problem : power saving ? attacking wacom ? no. some very stupid "feature" in the new bios from Toshiba.
quote from the toshiba download site:
*Version 1.70 - 2006-10-24*
*Incorporated Intel requirements for improved stability.*
**Made changes to ensure that the digitizer is not activated when the LCD is closed.**
*Version 1.60 - 2006-09-21*
*Changed the temperature parameters.*
i have no idea what they were thinking but since when i move i often close the lid, it's very, very annoying because i need to reboot in order to get my tablet working again. the more recent features are not a matter, i'll keep xp pro.
now give me a download link to get the version 1.6 of the tecra M7 bios. thanks in advance, i count on you.

Hello
Fact is that Toshiba offers all tablet PCs with WXP tablet edition and many additional software that offer full functionality when you use this tablet PC in tablet or normal mode.
So, in my opinion you should use tablet edition and install all available Toshiba tools and utilities.
I dont have much experience with tablet PCs but if you check Toshiba Europe support and download page under http://eu.computers.toshiba-europe.com > Support & Download you will see that your Tecra is fully supported for WXP tablet edition and you can download all necessary stuff.
Interesting is that there is also ready for download Installation instruction document with exact installation order.
You can also visit Canadian download page under http://209.167.114.38/support/Download/ln_bymodel.asp and see what is available there.
I really think you need to install all Toshiba specific tools and utilities to have full control and possibility to use it in both modes.
Sorry I cannot tell you more about all this.

Close the session when closing the opendoc link

HI,
Environment: BOXIR3.1 SP3 FP 3.6
When the user logging into infoview/CMC that time one session is creating , once logged off session also automatically closing. But when we using the open doc link, we dont have option to sign out the application. At that time we wanted to close the browser. But in CMC still we could see the users session in active. Could you please help us to kill the session when the browser is closed .
is there any possible to kill such kind if session in BOXIr3.1
Thanks
N/A

Hi,
You can only kill sessions using the SDK and it's not recommended.
Sessions should be automatically cleaned from the CMS after the timeout period. If it is not your case, follow the steps indicated in this KBA:

Prompt user to save change before abnormally closing the application

Hi,
I've some trouble prompting user to save change before abnormally closing the application (logging off, shutdownding machine...). I tried to use Runtime.getRuntime().addShutdownHook() and it doesn't seem to work. Here's part of my code. Help please!!!
program print out "1" and stays in a "dead-lock" mode...
private void shutdown() {
boolean saveConfig = true;
if (saveConfig) {
System.out.println("1 ");
int answer = JOptionPane.showConfirmDialog(null,
"Configuration has been changed. Do you want to save
configuration before exit?",
"Save Config"
JOptionPane.
YES_NO_CANCEL_OPTION);
JOptionPane.showMessageDialog(this, "Can't connect to unit. Error in Heal unit!", "Error", JOptionPane.INFORMATION_MESSAGE);
System.out.println("2 ");
if (answer == 0) {
savefileButton_actionPerformed();
jMenuFileExit_actionPerformed();
else if (answer == 1) {
jMenuFileExit_actionPerformed();
else {
return;
else {
int answer = JOptionPane.showConfirmDialog(itself,
"Are you sure you want to exit? ",
"Exit",
JOptionPane.YES_NO_OPTION);
if (answer == 0) {
jMenuFileExit_actionPerformed();
else {
return;
private class MyShutdownHook extends Thread {
public void run() {
shutdown();
// add shutdown hook
MyShutdownHook shutdownHook = new MyShutdownHook();
Runtime.getRuntime().addShutdownHook(shutdownHook);

doesn't much matter. shutdown hooks are not guaranteed to run or be able to finish.

Who knows how to make Word the default when closing Apple Works documents?

step by step if you don't mind? i've never used Apple Script. is this the solution?
thanks and Happy New Year

Your question about making Word "the default when closing AW documents" is a bit unclear.
An AppleWorks document is an AppleWorks document. If you want it in Word format, you must explicitly save a copy of it as such (and also append the .doc suffix to the proposed file name).

Cannot save opened tabs before closing the browser

Cannot save opened tabs before closing the browser. I do not know if there is such a feature (should be), and how to activate it.
It was very useful with previous version.

One change in Firefox 4 is to by default stop Firefox displaying the warning message, but it can be turned back on by changing some preferences.
# Type '''about:config''' into the location bar and press enter
# Accept the warning message that appears, you will be taken to a list of preferences
# Locate the preference '''browser.tabs.warnOnClose''', if its value is set to '''false''', double-click on it to change its value to '''true'''
# Repeat this for these 3 preferences '''browser.warnOnQuit''', '''browser.warnOnRestart''' and '''browser.showQuitWarning'''
If you always open the last set of tabs an alternative approach is this:
# Click the orange Firefox button, then select options to open the options window
# Go to the General panel
# Change the setting "When Firefox starts" to "Show my windows and tabs from last time"

T530 multiple display configuration lead to errors when closing the laptop

Hello,
I have a Lenovo T530 2429CTT and I am having some trouble when trying to set up my multiple display configuration with a Lenovo ThinkPad Mini Dock Plus Series 3.
I have an external Samsung LCD monitor which is connected to the Mini Dock via DisplayPort.
I am running Win 7 Prof.
The problem I see is with an application which uses DirectX. The display looks fine in the following configuration:
- Laptop open
- External Samsung LCD Monitor on
- Display cloned so that both devices show my desktop
The issues appear when I close the laptop. I do this because in my office I only work with the external monitor so I don't need the internal display of the laptop at that moment.
When I close the laptop the following happens:
The external display gets dark for some seconds. It comes up again, gets dark and after a while (maybe 10 sec) it stays active. Sometimes I see a notification that the color scheme has changed to Win 7 basic.
Everything seems to be fine now but when looking at the DirectX based display of my application I have some problems for example with the refresh (the display looks very weird).
BTW: The laptop has an internal and an external graphic card (Internal: Intel HD 4000, External: NVIDIA NVS 5400M).
So it seems as when the laptop gets closed, the internal graphics will be turned off. Due to this the display on the external monitor also changes the settings of the graphhic card (maybe it gets turned in an energy saver state).
I was looking at many of the NVIDIA settings without any success so hopefully somebody in this forum has an idea what is happening there.
Thanks,
Andreas

Hi,
I'm trying to buy the exact same configuration.
although i cannot find this 2429CTT on lenovo site anywhere, is available for selling on a known european supplier.
and my propose is to have 2 Monitors connected, so I'll follow this inquire very closely and hold my order until then.
do you have any update on it?
just by curiosity, what about the rest? how does the PC feels to you? everything else is working?
thanks

I want to save multable tabs when closing so when i restart i can resume previous sessions

before the last update..
i was able to save multable tabs before turning off my computer.
when i restarted my computer i would see the same tabs as i did before i turned off my computer.
i want this feature again please
i cannot find it anymore

Firefox now automatically saves open tabs when closing. When you re-start Firefox, do one of these:
#Restore from History:
#*click ''Firefox button> History > Restore Previous Session''
#*click ''History > Restore Previous Session'', if using the Menu Bar
#Restore from the about:home page:
#*type '''''about:home''''' in the Location/URL bar and choose "Restore Previous Session"
#*See https://support.mozilla.com/en-US/kb/common-questions-after-updating-firefox#w_why-werent-my-tabs-and-windows-restored
#Change your home page setting:
#*Change Options > General tab, change "When Firefox starts:" to "Show my windows and tabs from last time"
#*See [https://support.mozilla.com/en-US/kb/Options%20window%20-%20General%20panel Options window-General Options]
IMPORTANT:
*You must close Firefox using ''Firefox button > Exit/Close'' (or ''File > Exit/Close'' if using the Menu Bar) for this to work properly
*You must have "Remember my browsing history" selected; click ''Firrefox button > Options > Privacy'' (or ''Tools > Options > Privacy,'' if using the Menu Bar'')
**See [https://support.mozilla.com/en-US/kb/Options%20window%20-%20Privacy%20panel Options window-Privacy panel]

Then why are the guides unlocked when I reopen a document that I saved with the guides locked ?

The scroll function on my mousepad is disabled when viewing a pdf file in firefox version 5.0. The scroll works on the pdf, but not on the other tabs. When the pdf is closed, the scroll function returns to normal. Any ideas?!

Hey thanx for the help, it worked like a charm.
I think firefox changed the application lay out, as I used to be able to choose my PDF opener from the list at " Adobe Acrobat Forms Document' where I could choose Nitro-PDF reader, but it has now moved all the way to the bottom like you suggested to the obvious place of "Portable Document Format" section.
If someone didn't tell me , I wouldn't have scrolled all the way down to be able to find it... it really should be with all its cousins up the top...
Cheers again..

"...handle is invalid" : Error only when closing the Application, at RunTime everything seems fine...

HI,
first of all: I'm relatively new to LabWindows, working on it during some practical work as a Student
(yeah, and sorry for the bad english, I'm from Germany)
To the Problem:
The first important Information:
After having searched for a solution, I just don't know, what to do,
My Project consists of ONE Main.uir-File with a Tab, a "Main.c" that basically handles the main .uir-Stuff and some Initiating-Stuff and in addition to that Several Sub-Sourc-Files, one for each Tab-Panel of the Main.uir-Tab.
To use the UI-Items on the Main-Tab with the Sub-Sources, I am initiating Tab-Handles at startup, that can be used by the SubSource-Files, like:
GetPanelHandleFromTabPage (PANEL, PANEL_TAB, 2, &BALU);
With this Handle, I can identify every UI-Items, when working with the SubSources
The second important information:
In some of the TabPages of the .uir there are several ControlArrays. To use them I create a ControlArrayHandle, like:
MWSAverageHandle = GetCtrlArrayFromResourceID (BALU, MWSAverageArray);
No, I am able to identify specific elements of the Arrays, like:
SetCtrlVal (BALU, GetCtrlArrayItem (MWSProgressHandle, ActiveBalun), ProgressString);
Now there is a Problem, I am not able to solve:
During runtime, everything works out fine, I can use every element of a ControlArray with this ControlArrayHandle ("MWSProgressHandle"), everything works perfect, no errors at all. BUT, when closing the programm, I get the following error-message:
NON-FATAL RUN-TIME ERROR: "Baluns.c", line 313, col 16, thread id 0x00000AB8:
Library function error (return value == -4 [0xfffffffc]). Panel, menu bar, or control array handle is invalid
But this seems somehow ridiulous to me, because at runtime every single line works perfect, every Array-Item can be used without Problems...
Is there anything I am just not able to see???
Thanks a lot for your help.
Greeting from Lübeck, Germany!
Mathias
Solved!
Go to Solution.

Maybe I just figured something out:
First of all, most of the Functions, that cause the Error, are in Timer-Callbacks (at this state of development, ALL of them)
So I just added a Test-Function in a normal Button-Callback, which contains a "GetCtrlArrayItem"-Function, and this specific Line does NOT cause an Error... (Or at least it does not occur in the Error-List, when clicking "continue" in debugging-mode). Somehow the Timer-Callbacks seem to be called, when closing the Application...
BUT: this happens when I don't do anything in the Application, and the all Timers are Disabled, until some Buttons are pushed (so when I close the application right after opening it, they still should be disabled)
@ Wolfgang:
After discarding I do not want to use one of the handles, or at least I'm not doing that purposely
@ Roberto:
Actually I am only discaring the MainPanel-Handle in the Main.uir (and one other Panel, but the error occurred before implementing that other panel). Do all Handles (PanelHandles as well as ControlArrayHandles, TabPageHandles and so on) need to be discarded?
And no, I did not check the Variable Window, I was not aware of this possibility, I will try to figure that out.

Want my JFrame to be the *only* one that can end the program when closed

Hi all,
I have an application that is essentially a launcher for other applications -- it's a holder to allow us to demo our work and other Java examples (not necessarily our work). The launcher will either run methods to launch an application or will find a class's main method and invoke that.
In all cases, the other applications open up their own JFrames, separate from my launcher (this is a good thing). The problem is that, in general, the other JFrames are set to EXIT_ON_CLOSE. This means that if the user closes the second window, everything will close.
Is there anyway to prevent this from happening? I'd like either a way to say that my JFrame is the only one that can exit the program when closed, or to say globally that JFrames can't exit on close, and then re-work my initial frame so that it is still able to exit.
Note that changing all the other applications so that they do not include the EXIT_ON_CLOSE line is not an option (several of the applications we have the right to use, but not the right to modify, for instance).
Any thoughts?
Thanks,
Sam

I have a similar launcher application and this is how I tackled the issue....
Window[] windows = Window.getWindows();
This seems like a great work-around. The only problem is that Window.getWindows() is only 6.0, and unfortunately I can only assume 5.0. I can't see another method in the Window class that will return unowned windows -- is there another method that you know of?
Edit: I found I can use Frame.getFrames() instead, but unfortunately I've discovered this doesn't solve my problem. One of the applications is listening to window closing and is calling System.exit(0) itself, and is not using EXIT_ON_CLOSE as I previously thought. So I think that launching a new JVM may be the only option.... Any advice on how to do this? I'm a little stuck with the ProcessBuilder stuff above.

edit In future (not this time), Swing related questions should be posted in the [Swing forum|http://forums.sun.com/forum.jspa?forumID=57]
I guess I was thinking this as a process-oriented question (I had already been thinking of the "different JVM" tactic), but the other option was to think of it as a pure-swing problem, like your solution above. Guess I should have just cross-posted -- everyone loves that! ;-)
