Socket with graphics

hi folk
i have project to create client server program with multiuser
i know how to deal with threading server by bassing messages
but what about if all client will share the same board ( applet with graphics ) how can i deal with that ??

You have to express what the "board" means in a manner that can be passed over the socket.
For example...if you're writing a shared whiteboard type applet...then you could express the image or changes to the image on the whiteboard as lists of pixels, and then send those lists over the socket.
I guess you could also serialize the image and share that, but that sounds to me like it would be harder to synchronize between clients.

  • How do I use Automator to duplicate a folder with graphics on my desktop and erase their Resource forks?

    How do I use Automator to duplicate a folder with graphics on my desktop and erase their Resource forks?
    I do not use command line and tried to use ZapResourceForksAMAub_1.2 which I downloadedand instaled the Zap Resource Forks.action. Next I tried to use their sample copy-zap-rsrc.workflow in Snow Leopardon my Mac Pro. The 3 different steps are displayed in Automator but there is no place to put in which folder (on my deskto) to copy, and remove the resource forks from the graphic files.
    Can sombody please step me through this please please.

  • Black screen after login while on battery with graphics switching enabled

    Getting a black screen after entering my password while logging into my account while on battery with graphics switching enabled. Everything is up and running, I just can't see it.
    I can log into the guest account on battery
    I can log into my account while plugged into power
    I can log into my account on battery if graphics switching is disabled
    I believe something that is starting up in my account is causing the system to switch from integrated to discrete graphics on login, and that switch isn't working correctly on battery power.
    As a work around for now, I can run with graphics switching disabled, but I'd like to solve this so I get longer battery life.
    MacBook Pro Retina 15"
    Mountain Lion
    All updates applied

    I had the same issue and managed to reslove it.
    Shut down your machine.
    Power it back on while holding the 'shift' key (left or right, doesn't matter)
    You will see a greay progress bar go across the screen while you boot in to 'safe boot'
    Once booted, login, and go to Energy Saver and turn on 'Automatic Graphics Switching'.
    Reboot back in to normal mode, and you should be able to log back in and see again.
    I did this without being plugged into AC power.
    Hope it helps!
    Cheers!

  • Issue with graphics tearing on thumb scroll in Flex 3

    We are seeing some off issues with graphics (one using the charting package and the other using degrafa) tearing on thumb scrolling in a large Flex 3 app.  It's very hard to reproduce on OSX with the latest versions of Safari and Firefox, but it shows almost immediately when you run the app on Windows or Linux (regardless of the browser).  I took one of the pieces out of the app and put it into a very simple testbed app and can't get the problem to show on Windows (i was hoping to isolate the issue in a smaller test case, but no such luck).
    So, ii've got a few idea's on how to work around the issue, but i was wondering if anyone else has seen this type of problem before?
    Problem:   
         - graphics tear on thumb scroll
         - doesn't happen if you click in the track or use the arrows
         - one view is using the charting package, the other view is using degrafa
    Thanks for any comments or suggestions...

  • Batch create Multiple files in Acrobat X and X1 cannot convert Word 2010 with graphics

    I work for an exams board where hundreds of exam papers are produced. Once approved, these exams are converted to PDF and sent to print.  Using the Batch Create Multiple Files option is therefore essential to getting these papers print ready on time.  We have found that using this function to convert multiple Word 2010 files with graphics will not render it properly.  It deconstructs the graphics which loses the integrity of the exam paper. 
    I have trialled the same group of files on Acrobat X1 with the same result.
    Have other Acrobat Pro Users experienced the same problem?  Is there a fix? 

    I have uploaded the files and shared them.  These are the links

  • Indesign CS5 crash during startup - problem with Graphics.rpln

    I work in an architectural company and already several of our computers have experienced this very rare and unusual behaviour. During start up of Indesign (not clicking on any file but just launching Indesign) it crashes with the following error:
    "Adobe Indesign CS5 has stopped working"
    We use Windows 7 64bit, so the first step I did - I went into Application Log which says, so appears to be a problem with Graphics.rpln.

    I have tried everything I could think of - removed and reinstalled Adobe CS5, manually removed Adobe folders under %Appdata%\Local and %Appdata%\Remote folders (why can't Adobe delete those things during uninstallation is always a total mystery), changed video adapter drivers, cleaned Temp folders, everything I knew...
    None of the other apps like Photoshop or Illustrator CS5 malfunction - only Indesign. What is going on?
    Can it conflict with other software we use? We have Bentley Microstation, 3D Max, Office 2010, Kaspersky Antivirus and LOGMEIN installed on this computer...Any clues, guys?

    Looks to me like you've never installed any of the patches. Last patch for CS5 was 7.0.4, so I'd start with that and see if ti helps.

  • MSWORD templates with graphics look pixelated

    When converting Word templates to PDFs with both text and graphics, the text renders fine in the PDF, but the graphics look very pixelated and fuzzy and ragged.  Have tried both .doc and .docx files, and with graphics as JPG and EPS files.  Same results. 
    Any ideas here?

    They do print pixelated.  All content looks crisp in the word template, but any graphics still show as pixelated and ragged when PDF-ed. Smoothing is turned on.
    Thanks for the tip - any other suggestions?

  • Pdf (with graphics and text) in the email body

    When I place an pdf (with graphics and text) in the body of my email using Mac Mail my recipient sees them as attachments only. I am trying to find a way of presenting a formatted email with graphics that will appear the same way to all recipients, but a pdf frequently ends up being an attachment instead of staying in the body. The pdf  file doesn’t seem to always show up in the body as created. Is there a better way to accomplish this?

    You have no control over how your email maybe rendered by other email servers and client side software.
    Attachment Tamer may give you a few more options but it does not guaranty the end result.

  • How do I save emails with graphics into documents appear as broken page tried saving as html and all files

    I am using Windows 7, and ISP provider is AOL 9.5 dialup.
    When I attempt to save emails with graphics to My Documents,
    any graphics, usually in body of email as a bitmap or jpeg file, when I reopen email from My Documents, the graphics appear blank, as if a broken/torn page. Is there some settings I need to adjust on Firefox to be able to save complete files.

    I'm not a Mac user, that's my caveat, however there is a button on the ribbon for SharePoint Document Libraries on the Library Tab called Connect To Office.
    If that works with Office 2011 you'll start seeing your SharePoint site as a place where you can store documents in Office.
    Otherwise, you need to click "New" in teh library itself and have SharePoint open Office for you.

  • Problem running reports with graphics in 11i

    Hi,
    I have developed some custom reports (using
    Reports 6i) with graphics charts embedded within them. I would like to display the output from within Oracle Applications 11i.
    There seem to be two approaches:
    1. Invoke the report from Oracle Self-Service using OracleOasis.runReport
    2. Register the report as a concurrent request (with HTML/PDF output) and run it using the concurrent manager
    Approach 1 requires the reports server cgi which I start using adrepctl.sh. Approach 2 requires the concurrent manager which I start using adcmctl.sh.
    The problems start to occur depending on how and from where I start these scripts. The exact problem occurs in both cases.
    If these scripts are started:
    1. From a regular telnet window from a windows NT box
    The reports error out with a REP-3000 internal toolkit error
    2. From an Exceed xterm session and I keep the Exceed session alive (I tried both TrueColors and PseudoColors settings)
    The reports work but there are problems with the output - pie colors do not appear (everything is white, for e.g.), etc.
    3. From the Sun Solaris console
    The reports work fine.
    The problem is that method 3 is not very convenient since every time I bring down the concurrent manager or reports cgi server, I need to walk to a different building (where the Sun boxes are) to start it.
    Method 2 above isn't particularly great either (even assuming I can get it to work) since I need to have an exceed session running all the time.
    Can some one offer suggestions to solve the problem I'm having? Even clues on why method 2 above is not working as expected would be greatly appreciated.
    Thanks,
    - NR

    Problem solved! As long as the xhost + is set on the host machine and some one is logged in, it appears that one can simply set the DISPLAY environment variable to point to the host (even from a simple telnet window) and start the reports server or concurrent manager. Looks like you also have to have REPORTS60_NO_DUMMY_PRINTER set to "YES".

  • Frame in frame with graphics problem-or maybe not

    Hi from Croatia.
    Well I have and extremely demanding costumer that wants to control every single bit of the project.
    The problem is as follows.
    I have a book that every once in a wile has annotation which above and bellow has a graphic line (not simple line but complex graphic imported from illustrator.)
    I tried to anchor one object above and another bellow this text which lets say stands in the middle of text frame and for me everything works ok.
    But this demanding customer wants that those annotations are in separate frame so that he can have full control over them(?).
    So I made frame in frame-put wrapping around this smaller frame.
    The problem is- is it possible to put those graphics in this smaller frame, create text object and add it to library so that i can use it multiple times. I have more than hundred of those annotations.
    And is it possible when i cut the text from this main frame to paste it in this smaller one and that this small frame automatically fills with text so that frame expands vertically according with amount of text. I am not placing text but pasting. I hope you have understood but in every case here is an example.
    Main text frame(text fills full width of page)
    sadbhjasdsdab
    sagsafgsfgafsd
    agsfgfasg
    (Now smaller frame with graphic fills full width of main frame)
    ewfewtf
    agasg
    sdagasdga
    (text fom main frame continues)
    fasdfs
    dsgasgasg
    dfgdfsg
    dfsgsd
    Uf this was exhausting even for me.
    THX for any help.

    I tried to use 3 row table with header and footer, but the problem is that indesign does not allow tables to break when the part of table goes to another page.
    And THX for in for on those plugins.

  • Copy of source message to an element with graphical mapping

    Hi all,
    Is there a way to copy the complete source message of a mapping to an element of the destination message (with CDATA) with the graphical mapping (or UDF, but I want to avoid XSL) ?
    For example, from this message:
    <source>
      <element>test</element>
      <element2>test2</element2>
    </source>
    I expect the following result:
    <dest>
      <data><![CDATA[<source><element>test</element><element2>test2</element2></source>]]>
      </data>
    </dest>
    Thanks for your help.

  • Oracle support and compatibility with graphics cards

    I have been going through 2 weeks of hell getting any kind of meaningful information on Oracle linux 6.2 support for various graphics cards. I started with an ATI FireGl card that would not work with OEL 6.2. I am swapping that out in the seemingly futile hope that I can get an Nvidia GEFORCE 8800 to work. Either I am conducting my search using the wrong verbage(hard to imagine, but possible) or totally incompetant! I am here in one last desperate gamble that SOMEONE has gone through this pain before me. Maybe I am asking too much to be able to install 11GR2 on my server and still be able to use a Gnome desktop. Linux Mint worked perfectly with the ATI card, but alas, I could not install Oracle.
    Thank you in advance
    Dean

    From what I understand, the error means that the X Window server cannot find a display attached to your DVI output, which actually means it does not support the DVI port where your display has been attached to. This is a problem of the video driver that simply lacks support for your graphics adapter.
    I suggest to start by connecting only one display and verify it is connected to the DVI-1 port of the adapter. Support for DVI-2 requires support by the video driver.
    Enterprise Linux should work with graphics adapters that are standard with server hardware sold by HP and Dell. Graphics adapters you can buy over the desk from ATI and NVIDIA are usually designed for the end-user desktop/game market and are all difficult to get fully working under Enterprise Linux. You can check the vendor support page to see if they provide driver support for SUSE and RHEL, but I doubt that it will work with the Oracle Linux UEK kernel. Driver software from these vendors are not open source and require a specific Linux kernel. Alternative drivers exist for http://nouveau.freedesktop.org/wiki/ for NVIDIA, but your success will vary, in particular if you need to support 2 monitors, which is not a typical server system setup.
    You might have more luck using a Linux distribution for desktop systems, such as Fedora or Ubuntu. What you are planning to install from Oracle? It is easier to get Oracle Database working on unsupported Linux than trying to hack a video driver to support advanced features on an unsupported operating system. Or try a complete different approach and install Windows and use virtualization, like Oracle VirtualBox to run Oracle Linux out of the box. I would prefer to use virtualization even if my desktop computer would run Linux. There are just too many advantages I would not want to miss anymore.

  • EP6.0.2 Create new workflow template with graphical editor

    Hi!
    In the EP6 Content (Administration -> Workflow Content -> Workflow Templates) you can find an iview to generate templates for ad-hoc (java-) workflows.
    After installation the button "Create New Template" is disabled.
    How can I configure the EP to create new template with graphical editor? Or should I wait till SP4 is rleased?

    Hi Henric,
    We have had to develop our own way of creating templates.   This area seems to be very underdeveloped at the moment.

    Hi,
    have a look at the pdf that comes with the download package. It describes how to structure your data (depending on the chart type).
    Use the Chart Designer to create your customizing settings (chart type, colors etc) and save them as a customizing XML file.
    Finally have a look at report GRAPHICS_IGS* that shows how to use the XML in your own report and send them to the IGS (by using the class CL_IGS_CHART_ENGINE).
