Detect the first application running

I create an application with a SQLlite database in the SD card. The application is already installed in the device and the database has already been created on the SD card.

However, I have a newer version of the application and a newer database structure for it. I want to change the database table when the user launches the application newer version for the first time.

The problem is: how to detect that the application is running for the first time?

You have many options to do so, but according to my suggestion, you can have an object stored in the persistent store to indicate the version of the app and start can check if the application has the same version number as the stored object.

  • I'm not able to install both on the same PC LabVIEW applications. I have uninstall the first application in order to install the second. Is there a way to avoid this?

    I wrote two LabVIEW applications. The first acquires data from three different devices, displays the data and writes it to a file. The second application reads the data and displays it on the screen.

    Can I install the first application and run it, but I can only install the second application if I uninstall the first application.

    Any ideas as to why this is happening?

    You install applications by using a Setup program created with the application builder to LV?

    What LV version do you use?

    You have a dedicated for each installer build script, or do you still want to change the settings of a single build script (which would be a reason for this behavior!)?

    hope this helps,

  • How to detect the first keypress entry in VI reloaded

    Hello.

    I use VI popup information in TestStand that I want the user to be able to output/confirm using Enter/Return, and I use a key event down in a structure of the event to detect they keypress.

    But the problem is that when the VI is already loaded in TestStand, the structure of the event does not detect the first keypress enter/return.  If I detect the space bar, it works fine.  But enter/return still need first press key before be detected as a key event down.

    Anyone know why this is?

  • The Linux Application running on vmware license validation

    Hi all

    We sell our software based on linux on our custom server hardware platform. We intend to make the vmware as a platform officially supported. We will distribute only computer image virtual and clients will have to arrange their own ESX VM server.

    License of our application is generated using eth0 MAC from our server unit. So the license of the application generated for a mac address, on the device only one server (i.e. a license is linked to a server machine). Same license does not work on any other device server due to the mac address verification.

    In ESX VM, mac address can be automatically or manually assigned to a VM vNIC:

    1 auto generated MAC:

    ===================

    We leave the ESX Server to assign an automatically generated mac address to our VM.

    Limits:

    License currently applied to our application will not work in the following cases, which are very likely to occur in the field:

    a. If the virtual computer is moved to another ESX Server, automatically generated the MAC address for this virtual machine will change.

    b. conflict of MAC address of is not guaranteed.

    If a virtual computer is stopped, the same generative MAC may be assigned to another VM that happens while the virtual machine is broken.

    Later when this virtual machine is displayed, it will get a few other self-generated Mac.

    2. manually configured MAC address:

    =============================

    Disadvantages: Possibility of piracy, because the user can specify the same MAC to several virtual machines of our application that runs on different ESX servers and apply the unique license.

    How about the other applications that run on vmware, handle request license validation?

    Is there any "unique globally identify" for each VM instance that can be used to generate and validate the license of the application?

    Kind regards

    Manish

    Licensing could be a problem if based on the MAC address.

    As you wrote if you use a MAC address manually it can also be defined by the user.

    If you use the automatic type, there is another problem.

    And anyway Linux is fairly simple spoof the MAC address...

    Using the properties of the drive, as UUID or special block could simple derivation by cloning the entire disk with JJ.

    CPUID properties can not be used...

    Have you considered using a solution based on the license server?

  • Detect the first and last spark of list items

    Hello

    I have a converter item personalized with a background image for each item in a list. the thing is I'm trying to have a different background for the first and last elements (curved respectively) and I don't know how to do this.

    Any help will be appreciated.

    not sure it's the best solution, but:

    You can override the method to data defined in your itemRenderer. Compare the new data for the first and last items in your list. And you set the background depending on the result.

  • Detect the hardware to run VI

    I'll preface this by saying: I'm in the early stages of learning about Labview, if it's probably obvious by my question.

    I want to just run my VI if a specific device - a NI USB-6229 (Dev1) case is detected, both at the start of the program at any time during the execution of the program I'm only using this device and my program is not intended to be used on any computer other than mine, so I don't think I need a table of product names or device types as I've seen in other posts and examples of programs. I don't want to add anything to the façade. I just want to stop running my VI if data acquisition is not connected or becomes disconnected at any time. Below is what I want to do, if I understand is not the right way to code.

    Any help would be appreciated!

    That's how you get the type of device.  Maybe this will help you get started.

    Thank you
    Arun

    Fixed it :)
    I had to put the following parameter: IntradocServerPort = 4444

    When I ran my program I saw results in my table. Also, I do not see the warning...

    I used the search instead of getItems operation.
    I need to set the path to "/" and recursive to true in order to see the results in my table.

    When I use the getItems operation and set the path to "/" and run the file, I get a single record with the record of the contribution.

    I notice in your links, you use links to set the path, so I think you want the user to go through the files and update the list when the user selects a folder, correct?

    To test your connection, set the path in your links to the getItems operation to / instead to your EL expression.
    If you have a result, that there is something wrong with your logic. If you do not see a result, there is something else wrong.

    For example, here are my links:

  • [JS] [CS4] Search pages to find the first application of a master spread?

    I'm working on a script that search masters spreads for specific text. Once it is found, the master spread name is returned. Now I'm stuck looking for pages to find where this master spread is applied first. Any help?

    var doc = app.activeDocument;
    
    app.findTextPreferences = app.changeTextPreferences = NothingEnum.NOTHING;
    app.findChangeTextOptions.includeMasterPages = true;
    app.findTextPreferences.findWhat = "custom text";

    if (finds.length > 0) {
        
              var mspage = finds[0].parentTextFrames[0].parent.name;
              var dpage = doc.pages[0].appliedMaster.name; //This of course is not right, it's returning the name of the master spread for whatever page is currently selected. So how do I set the current page to the page that first uses the found master spread (mspage)?
    

    You will have to look for him.

    var i, dpage;
    for (i=0; i<=doc.pages.length; i++) {
      if (doc.pages[i].appliedMaster == mspage) {
        dpage=doc.pages[i];

  • Read a string and detect the first group of 8 numbers

    I want to take an information from the string within a string (file name or folder name)

    The string I want to take is a number of 8 digits (side by side) and it may be somewhere in the middle of the chain.

    For example:

    Large chain A:

    Great channel B:

    I want to always read the 10097822

    How can I do that with the code in a function that returns the number I want to?

    You can try this...

    var numberFromString = getNumbers("_v_nkld3sgrf10097822-YVES.SAINT.LAURENT.273456YOD02.4176.Silk.15113");

  • Application runs slow after deployment

    With the help of JDev 11.1.1.6

    I have developed a fairly broad application using business components based on tables of Oracle database and it works very well in the IDE.

    The application has many pages.  Each page queries the database when the page is loaded.  The deployed application runs very slowly when you query the database for the first time.

    I checked the database session and it's not slow it down.

    Are there things I can do to improve performance?

    Are there available diagnistic tools that can pin-point where the downturn occurs?

    Thank you

    Raymond

    Additional information: the application is using page fragments and dynamic flow for navigation task.  Most of the time is between the time you click on the link and the time that the page is traversed.

    It is a normal behavior. By default, Weblogic compiles JSPs on their first use, which takes a while. If you want to precompile JSP pages to deploy in time, you must add the following to weblogic.xml application descriptor:

    ...

     

        true

  • IMAQ edge tool 2 'first + last edge' - returns the position of the first border

    Note: it detects the edges along the long green horizontal line, so there's at least 2 edges definitevely.

    Hey Martin,

    This may sound silly, but what happens if you scroll down to the following entry in your cluster? Currently, you can view information for your benefit '0' on the front panel. What happens if you are indexing at the edge '1' of your cluster and therefore see the information on the second edge. Is the cluster of empty when you look at the 'zero' edge? If it is, perhaps, the parameters of your step edge find are too strict and the step does not come back on a second advantage.

    If the problem persists, maybe post your vi sample and a sample picture will help clear things upward.

    I hope this helps!
