• Catch the event close application?

  How can I catch the close application event? Can someone tell me the api to use? Thanks in advance.

  Create your own features to clean up when the application is going to come out.

  Do not call System.exit (0) directly in your application.

  Implement a method that makes all cleaning operations and calls System.exit (0) after all.

  And only call this method when you want to leave.

• How to create a "band of the art" in LabWindows/CVI

  Hello

  I am well aware of how it is easy to do in LabView, but I can't seem to find all the information on how to do this in Labwindows. There are other ways I can close a fall tips, but I really like what the end of the strips do for me.

  The CVI equivalent is called "tooltip" and is defined by program based on SetCtrlToolTipAttribute (): with the attribute CTRL_TOOLTIP_ATTR_ENABLE you decide whether to show the ToolTip or not, whereas with CTRL_TOOLTIP_ATTR_TEXT , you set the text to display. The links are using CVI 2009. There are a few caveats when using ToolTips: here a case where balloons are carried forward off.

• catch the event of closure of the main window (air)

  Hi flex community.

  My question is how can I manipulate it as the user closes the application (in my case a windowed application: air) that a warning message asks the user if he really wants to exit the application.

  I would be happy for any helpful answer.

  Greetings

• Catch the event Web Service Session Timeout

  Hi all

  I have a LV Web Service communicate to a web client (Chrome, IE, FF, etc.).  The user connects to the server and create a new session for him to help create Session VI.  One of the entrances to this function is a timeout value (default 60000ms).  The sessions behavior is such that if the user does not activate an application for web service (GET/POST/PUT/etc) within the time limit, then the session is automatically destroyed by the web service.  That's what I want, it's fantastic.

  My question is How can I detect when the session timeout happens? Another way to say, How can I detect when the user session is automatically destroyed?

  What I tried:

  • Of course, I can provide a "logout" link to the user calling ultimately "Destroy Session" VI, but I can't count on the user actually click this link (e.g. you really explicitly sign out of gmail or simply close your web browser?)
  • I thought that the only way to proceed would be to save the cookie of session ID returned by create Session VI and then query this ID to see if the session still exists (check if Session exists VI).  If the session does not exist, well, I know it has expired or the user manually destroyed it.  However, even if I save the cookie ID, I don't see where I can actually use it any where (especially not check if Session is VI). It just seems no value given to the range of sessions.

  Is this possible?

  Thank you

  Rory

  Sorry, Thomas, but that isn't going to work.  Think about it - you do not request a web service during the time-out period. You get ONLY a web service request when the client actually asked something.  The customer does not have during a timeout; It's just times out... so, there is no node on the block diagram to check because there is no block diagram... get it?

  No worries, however, I found the solution [read: workaround], even if the LV can do it (from 2013sp1).

  The best way to detect if a user session times out / out times would be for LV to this exhibit as an event in the web service. The following approach would be for LV accepts a cookie as an entry ID and then provides information on this session (i.e. the session exists).  I have a smell of two feature requests...

  But because BT cannot do these things (or not exposed to the developer), you will need to get creative on the client side.  Since I'm on Javascript/jQuery/AJAX on my front end, then it is possible for me to detect when the customer leaves the page or close the browser.  It comes to $(window) .unload () in jQuery.  Then, I can take this event and an asynchronous AJAX command of fire to one of my web service VI that will eventually call the "destroy Session" VI.

• How to force the compilation released executable before running the distribution of LabWindows/CVI kit?

  I am new in 2015 of the CVI. I used CVI 7 and when I chose "Create the Kit of Distribution", when I was still in debug mode, Labwindows asked me to build the executable of setting before creating the Distribution Kit. This does not happen to CVI2015, and the Distribution Kit is created with the latest built executable version, although I made a few changes in my code! This is a problem since I work in debug mode and I usually forget to build the executable of liberation before calling the distribution kit, so I need CVI to do it automatically like CVI 7 did. I suppose that there is an option to do this, but I can't find. Can someone tell me please how to resolve this problem and force CVI to build the exe version before building the distribution kit? Thank you.

  Today, I've solved quite simply create a new distribution. The previous like unsing was automatically imported by CVI7 project. By creating a new distribution, now when I change something, CVI ask me if I want to build the release. So I did not understand the problem but I solved it by editing a new distribution kit.

• How can a separator or the second column in the combobox with Labwindows/CVI?

  How can I make custom editable as attached file (Example.jpg) using the ICB library?

  The ComboBox to the figure of capture via MS tool.

  I am a novice in programming as well as the CVI. Please explain in detail if anyone knows.

  You can do this, but it will shows. You can add columns in the control ring menu, so you'll have to create your own popup with a tree control that replaces the menu ring. I have attached a sample program as proof of concept and you get started.

  Hope this helps,

• How to catch the event up, down, left, right button. Help me!!!

  I want to catch even down, left, right, I coded like this:

  {} public boolean keyChar (key char, int status, int time)
    
  If ((key==Characters.CONTROL_UP) |) (key == Characters.CONTROL_DOWN) | (key == Characters.CONTROL_LEFT) | (key is Characters.CONTROL_RIGHT)) {

  Returns true;
  }

  If {(key is Characters.ENTER)
  Dialog.Alert ("Enter");
  Returns true;
  }

  Return super.keyChar (key, status, time);
  }

  But only Characters.Enter can be caught, but Character.CONTROL_LEFT, on the RIGHT, upwards, downwards cannot be caught. I work with BlackBerry 8820 Simulator. Please help me. Thank you

• CAObjHandle handle ActiveX object to the NI LabWindows/CVI 2009 Server

  Is there a way to create a CAObjHandle on the ActiveX of LabWindows/CVI server without opening a new application of CVI?

  A bit of history, I am trying to automate the creation of files in HTML help by function panels. Thanks (http://forums.ni.com/t5/LabWindows-CVI/Is-there-a-way-to-automate-generating-the-documentation-from-... I have found that there is a function that exist to achieve this.

  CVI_AppGenHtmlHelpFromFPFile is the function that I need to call, but I got a handle created.

  I can get a handle to it using the CVI_NewApp function, but the problem is that it opens a new application of the CVI (which is certainly not favorable). At a very high level I need this feature to treat more than 100 panels of function in order to see how this can become a bit extensive and involved to open CVI every time. It should be a relatively small appilcation of command line that basically takes the path of the file and go to CVI_AppGenHtmlHelpFromFPFile and it does its magic.

  Any help on this would be greatly appreciated.

  Thank you

  Do you need to treat each Panel function in separate your program calls? If so, is it possible that you could treat several panels by invocation?

  If you're really stuck to running a separate process each time, can you pass some indicator of command line to your program to tell him to close CVI or not? If you don't stop it, then your program can always use CVI_ActiveApp and it would keep reusing the same instance of the CVI over and over again. Then when you call your program for the last Panel of the function in your loop you might pass a command line flag saying it close CVI before leaving.

• difference of initial value of string between the steps in the process and an external instance of LabWindows/CVI

  Hello

  I'm curious to know what I see using TestStand, LabWindows/2013 2013 with regard to initial in TestStand string values when you perform the steps in the process or an external instance of LabWindows/CVI.

  I have a step (CVI) string value that is used to check an array of characters stored in an EEPROM to test.  I pass on the Step.Result.String in the CVI by reference.  I then read the table charater of the EEPROM in the chain (Step.Result.String).  The string is then compared against the limit as specified in the test step breast.

  When I run this test step to perform the steps in the process selected in the popup Configuration of the adapter of LabWindows/CVI, it seems that the memory allocated for the string is filled with null characters.  Which is what I expected.

  When I run this test step to execute the steps in an external instance of LabWindows/CVI iselected of the Configuration of the adapter of LabWindows/CVI popup, it seems that the memory allocated for the string is filled with something else.  That is not what I expected.  For example what I see in the memory, it's the first characher is one byte NULL but the remaining bytes are some other values, as shown below:

  F0 00 AD BA 0D F0 AD BA 0D F0 AD BA 0D AD BA 0D AD BA 0D BA 0D AD F0 F0 F0
  F0 AD BA 0D F0 AD BA 0D F0 AD BA 0D F0 AD 0D AD BA 0D AD BA 0D F0 F0 F0 BA...

  In my code I make sure to write a null character in the following location table charater I just write in the chain so I have no problem with the test is working properly.  I have remove the writing from my code null character and was able to verity that the test passes when executing the steps in the process and fails during execution of the steps in an external instance of LabWindows/CVI.

  The returned string contains what I wrote for her, and then the rest of the string is filled with the values that are in the memory allocated for the string.

  Here's my Question: is this the expected behavior for the original string values in TestStand between both types of stage performances?

  Thank you

  Chris Young

  In general teststand not Initializes the unused portion of the string buffer, so it is expected that the values of the memory after character no endpoint will be different, or even to each call. If you happen to be get zeros after the null terminator which was probably due to random character (i.e. the memory allocated just arrived already having zeros in there) or perhaps a debug setting you use perhaps in the Visual C runtime (if you are debugging the process in visual studio or modify visual C runtime heap parameter). TestStand is not initializaing memory after the null terminator character in both cases (I checked the code).

• LabWindows CVI and debugging dll MSVC ++

  We use a written LabWindows/CVI DLLS in the code for Teststand module. This DLL calls a DLL written in MSVC ++.  Is it possible to use the debugger of Labwindows/CVI debug this DLL MSVC ++ (if this DLL MSVC ++ is built with 'good' options)?  Or is possible only using the environment of development MSVC ++?

  Hello mkossmann,

  The CVI compiler generates different types of than MSVC debugging information.

  The debugger CVI doen't understand the debugging information generated by MSVC, so you cannot debug the dll compiled in MSVC.
