  • How can I find which applications are using the most power?

    I have recently noticed a full charge of power doesn't last as long as it used to on my iPad 2.  Is there some way to determine which applications are using the most power?
    I have been monitoring my home network router accesses and have noticed the iPad logs accesses every 15 seconds.  This only happened recently.  It had been well behaved and only accessing once or twice a day before.  I installed the most recent iTunes upgrade, per suggestions during a Sync.  The problems seemed to occur after this update.  I have gone through all the settings and have minimized the applications requiring higher power (I switch off the location services unless I'm away from home.  Likewise, I turn off my cellular carrier unless I'm away from home, etc.)
    In short, how can I maximize my power usage (aside from turning it off)?
    Thanks.
    Dave

    Thanks for responding so quickly.
    I'm really trying to find out why the battery is depleting much faster than it used to all of a sudden.  I used to be able to put a full charge on it and it would last about 5 to 6 days with normal use (normal for me).  Now that battery only lasts about 2 to 3 days with the same use.
    I DO recharge it when it needs to be charged but this is indicating there is something else (new) that is causing the power drain.

  • How can I allow other applications to use vector image data in Flash CS5?

    Specific to Flash Professional CS5. With its export options greatly reduced, there seems to be no way to make Flash graphics accessible by other programs. Is there any workaround?
    Currently, Flash can output two kinds of vector images: SWF and FXG, neither of which seem to be importable by most applications, including Fireworks and Illustrator (which write to FXG but not read from it), and Catalyst doesn't seem to write to anything other than what Builder uses. In other words, I know no way to export Flash files to vector formats (besides using Flash CS4).

    Hello
    http://cps-internal.corp.adobe.com/cps/150/tn_15022.html
    It says :
    Director supports a wide variety of graphic formats. Vector  graphics are supported as native vector shapes (#vectorShape) or as  Flash SWF files. Vector shapes are created in Director using the Vector  tool. Often, developers need to import art created in an illustration  application such as Macromedia FreeHand, Adobe Illustrator or CorelDRAW.  However, EPS, AI, FH9 and CDR file formats are not natively supported  in Director and cannot be imported without the use of an Xtra or  plug-in.
    It is possible to save artwork created in Macromedia FreeHand as a  SWF file, which can then be imported into Director. For Adobe  Illustrator and CorelDRAW users this can also be accomplished using the  Macromedia FlashWriter plug-in for Adobe Illustrator or the CorelDRAW  Exporter. These plug-ins are available for free download at the Flash Download Center for registered users of Illustrator and CorelDRAW.
    EPS files may also be imported into Director using a third-party  Xtra. The PS2VS Xtra from Moshofsky/Plant Creative Services for Director  7 and 8 works on both Macintosh and Windows operating systems. The Xtra  can be downloaded from the Moshofsky/Plant PS2VS Web page.  The current version converts Adobe Illustrator (EPS and AI files) and  Macromedia FreeHand EPS files to Director 8 #vectorShapes.
    Note:The PS2VS Xtra is a third-party product and is NOT supported by Macromedia or Macromedia Technical Support.
    Will this work ?

  • How can we develop flex application as 64 bit application?

    I develop a 32 bit application through flex and i want to convert as a 64 bit application.
    Is there any way to develop?

    I may be wrong, but isn't the architecture ( x86 , 64bit ) the concern of the VM. That is one of the motivations for having a vm, you don't have to worry about the architecture your application runs on ( for the most part).

  • How can a Visual Basic Application be used to read a Netscape LDAP server?

    I would Like to know if Visual Basic (ON AN NT WORKSTATION) can be used to access a Netscape LDAP Server (ON UNIX). And If so, will any API calls be necessary? Is there any documentation on using Visual Basic with LDAP?

    Hi Ryan,
    yes you can use VB with the nsldap32v30.dll or nsldap32v30.dll. You can get this from the iplanet page . The dll is inside the LDAP C SDK. Then, there's a 3 or 4 year old vb sdk with the declarations of the LDAP functions; but this seems not to be available in the web.
    Please send me a mail, I'll send you the doc and a sample vb prog.
    remove the nospam.

  • How can I develop EJBs using JDeveloper?

    Hi all.
    How can I develop EJBs (entity beans) using JDeveloper and deploying them on WebLogic6x
    server?
    Oracle says that JDeveloper enables to build and deploy applications to the WebLogic
    6x, but I can't do that with Entity Beans(CMP).
    I established the connection to the WebLogic and to the DataBase and they work.
    JDeveloper generate ejb-jar.xml and weblogic-ejb-jar.xml but not weblogic-cmp-rdbms-jar.xml.
    How can I build all the necessary xml's files? What I have to do? Exist a pluging
    to integrate JDeveloper with WebLogic?
    Thanks, and I hope your answers.

    hello,
    in reports 6i the charts are created using oracle graphics which stores the chart definitions in a separate file (.OGD). there is not XML interface for graphics.
    with reports 9i and the introduction of the BIgraphBean the definition of the chart-properties is also done in XML.
    reports 9i will be available with iAS Release 2.
    regards,
    the oracle reports team

  • How can i run Webdynpro application

    How can i run Webdynpro application without using Developer Studio? Where should i put a whole project and how shoud i start it.
    Thanks!
    Maciek

    Hi Maciej
    You wouldnt require a Developer Studio to run you
    application.But you would require it to deploy (if are
    using the JDI ,atleast to perform an Activation).
    However you can launch the application once deployed
    through the Web Dynpro Content Administrator
    http://<servername>:50000/webdynpro/welcome/
    The deployed applications are present on the
    lefthandside. They can be expanded to drill down to the
    Application and the press Run

  • How can one develop "view only" client applications in Lookout?This is to develop remote monitoring without control functionality.

    How can one develop "view only" client applications in Lookout?This is to develop remote monitoring without control functionality.
    We have 10 Client Nodes in the field and we need two "View Only" functionality in Client machines located on Supervisory Desks.

    I have done this. There are many ways to approach this but I will offer what I think is the easiest. This will work ONLY if you have been assigning security levels to your objects (objects that actually control devices in the field) greater than zero AND allowing a security level of zero to view all panels. When I develop interfaces I do this just for creating a non control client.
    Basically, you remove all users from the Lookout client in the user manager. You will not be able to remove the built-ins, "Guest" and "Administrator". Now when the end users tries to login using his normal login he will be denied. Consequently, he will not be able to control. But, he will still be able to view all the information since a no login can view a panel with a viewing se
    curity level of zero. You must ensure any pushbuttons that are used to open panels have a security level of zero.
    Now you can copy this security profile by finding the lookout.sec file and copying it to another non-control client computer. In Windows NT this file is located in the system32 directory.
    There are many other ways but I find this the easiest.
    Regards,
    Tommy Scharmann
