Lag when you draw a square by using the property plotimages.back on XY graph

Hello

I'm developing a simple program where you enter 2 vertical sliders on a XY chart by selecting coordinates X and then it should highlight in yellow the area between the two mentioned sliders.

The issue I'm having, is that even if the program is inspired by the square on the graph, there is a shift, which I can't get rid. I checked the input coordinates to draw the square and they seem correct, however, the gap is still there...

Please find attached my program, thank you very much for your help!

Well, I found the reason. To eliminate the offset, you must get the graph XY plot area limits and subtract 'top' and 'left' your coordinate of the cursor values

  • I have a problem when you try to receive data using the socket connection.

    Hello

    I created a socket connection between a pc (sever, win32) and a blackberry (client) and I have only two questions:

    -When I send a string to the sever I get the unexpected result, I doubt if it's a problem of encoding between platforms.

    -When I try to receive data, (an array of char as a string object), the customer demand freeze (drawing and management of events, so basically the main UI thread), even if I did all the stuff of connection in a separate thread, until I have shut down the server and also no data is received.

    You treat on the thread of events.

    You have the following code:

    UiApplication.getUiApplication () .invokeLater (new Runnable() {}

    public void run() {}

    try {

    open_connection();

    .....

    Now invokeLater essentially tells the operating system that the associated executable must be run on the event Thread.  You need start a separate Thread.  Extend this Thread, add your code in the run() method, and then start the Thread with start(). (not run()).  Then you must run the networking of processing on a separate Thread.

    This will cause you problems updating the user interface.  Take a look at this help:

  • RDSH Lag when you browse the gateway SSL Secure-IT

    Hello

    I have a ticket open with support Dell/Quest, but thought I'd post here this ongoing problem where someone can help you.

    Question:

    I'm on version 8 vWorkspace and all servers are virtual Win2008R2 on ESXi 5.  When clients Web Connector (Windows or Mac) connects to RDSH gateway SSL Secure-IT, there is a noticeable lag when you type, hanging out windows, move the slider mouse around the start menu, etc.  All of our users to put to test is complained about this, because it affects their normal daily work.

    It is compared to customer standard RDP Windows, as well as bypassing the Secure-IT.  Bypassing the Secure-IT, the LAG disappeared completely.  The offset is also noticeable when comparing in the unique environment of LAN.

    EOP all off except for the extreme EOP EOP Flash and EOP printer.  I also tested with EOP all features are disabled, but it made no difference.

    All features of Windows disabled (smoothing of the fonts, background, etc.)

    My infrastructure:

    Internet (users)--> firewall SonicWall--> LAN (Secure-IT, Web - IT, connection broker, RDSH servers)

    The virtual machine of the LATTER was in the demilitarized zone, but to help out, I moved it inside the LAN which made no difference.

    The machine virtual Secure-IT has a lot of resources I can see that the CPU and the RAM hardly moved.  And I'm testing only with one or two connections in all cases.

    I tried to appoint the former Secure-IT version 7.5 executable, which further aggravates the offset.

    At this point, it is a show-stopper for us.  I hope that this can be resolved as vWorkspace is the best solution for us in terms of ease of use/connection for our non-techie users.

    Help!

    I discovered what the problem was.  I disabled the journaling on the IT security and the offset is now completely gone.  I found out about it on a post on the forum of Quest vWorkspace in 2010.  http://en.community.Dell.com/TechCenter/virtualization/vWorkspace/f/4827/t/19551509#1880

    So, I think Dell/Quest should document this, put in a basis of knowledge, or difficulty Secure-IT (pnsslsvc.exe) service, because it would help a lot of people.

  • When you send an e-mail using Outlook Express, I immediately get this message; "Some errors occurred while processing the requested tasks. Please see the list of errors below for more details"

    When you send an e-mail using Outlook Express, I immediately get this message; "Some errors occurred while processing the requested tasks. Please see the list of errors below for more details". Unfortunately, there are no errors listed below and the green bar is frozen on the screen. The message remains in my Outbox and repeated again and again sending. There is absolutely no record and file sent in my sent box. TIA - Ernie

    You have apparent dbx file corruption. A common problem.
     
    Spend most of your messages out of the Inbox and then create new folders to send and sent items box after having moved the messages you want to save to a local folder that you create.
     
    Tools | Options | Maintenance | Store folder will reveal the location of your Outlook Express files. Note the location and navigate on it in Explorer Windows or, copy and paste in start | Run.
     
    In Windows XP, Win2K & Win2K3 the OE user files (DBX and WAB) are by default marked as hidden. To view these files in Windows Explorer, you must enable Show hidden files and folders under start | Control Panel | Folder Options icon | Opinion, or in Windows Explorer. Tools | Folder options | View.
     
    With OE closed, find the DBX files for the items in the Outbox and sent and delete them.  New ones will be created automatically when you open OE.
     
    After you're done, followed by compacting your folders manually while working * off * and do it often.
     
    Click Outlook Express at the top of the the folder tree so no folders are open. Then: File | Work offline (or double-click on work online in the status bar). File | Folder | Compact all folders. Don't touch anything until the compacting is completed.
     
    General precautions for Outlook Express:
     
    Do not archive mail in the receipt or sent items box. Create your own user-defined folders and move messages you want to put in them. Empty the deleted items folder daily. Although the dbx files have a theoretical capacity of 2 GB, I recommend all a 300 MB max for less risk of corruption.
     
    Information on the maximum size of the .dbx files that are used by Outlook Express:
    http://support.Microsoft.com/?kbid=903095
     
    Disable analysis in your e-mail anti-virus program. It is a redundant layer of protection that devours the CPUs, slows down sending and receiving and causes a multitude of problems such as time-outs, account setting changes and has even been responsible for the loss of messages. Your up-to-date A / V program will continue to protect you sufficiently. For more information, see:

    Note that for some AV programs, it may be necessary to uninstall the program and reinstall in custom Mode and uncheck analysis when the option is the result of e-mail messages.
     
    Compact often as specified above.
     
    And backup often.

    I get an error 0 x 80070570 when you access my flash drive using windows 7, but the same flash drive works perfectly on two other PC's with Windows XP. It's frustrating because I need to backup and transfer files.

    Hello
     
    1 you get an error message with this error code?
    2. is it a problem with this particular flash drive only or all flash drives?

    Let us run the check disk utility.
    Here's how:
    a. open the computer by clicking the Start button, click computer.
    b. click the drive you want to check, and then click Properties.
    c. click on the Tools tab and then, under error-checking, click Find now. If you are prompted for an administrator password or a confirmation, type the password or provide confirmation.
    To automatically repair problems with files and folders that the scan detects, select automatically fix file system errors. Otherwise, the disk check will be a problem, but not to fix them.
    To check for errors file and the physical errors, select both automatically fix errors in file system and search for and attempt recovery of bad sectors.
    d. Click Start.
     
    Depending on the size of your drive, it may take several minutes. For best results, do not use your computer for any other tasks while it checks errors.
     
    Important: Running chkdsk on the drive if bad sectors are found on the disk hard when chkdsk attempts to repair this area if all available on which data can be lost.

Then after a few hours it seems to lose the mapping on the drive. There are two mapping drives and he loses a. It will show in my computer as being mapped, but you cannot access it. You can connect to the mapped drive on bringing the command run and typing in the UNC path in.

    Hi all

    When you create a new DP, use sizes offered by InDesign or the size of the unit?  I fell on this question when I was looking for the sizes of the various devices and found that the iPhone 5 s, iPhone5c and iPhone4s sizes differ the defauly dimensions offered by InDesign.

    Also, should I worry about the DPI of resolution?  With the iPhone, they all seem to be 326ppi, but when it comes to other devices it's something I should consider?  Ideally, I could create DPS apps for all devices offered in digital publishing in InDesign (iPhone, iPad, Kindle Fire/Nook and Android).

  • funny things happening when you draw a line

    We're talking Ai CS5.

    I have a work plan with a mixture between 2 wavy paths, the kind of thing that you hope that the customer will not ask new :-)

    A path is in line with a horizontal guide at the top on the artboard and down by another.

    I draw a line between the two guides and nowhere segment near the mixture and expect to get just a boring straight line. Instead I'm out a lengthened version of the plantings, starting at the top with the first path and passing all stages of mixing arriving downstairs with the second path.

    Sorry, I have to describe it that way, but when I tried again once it no longer works, so I can't show you the result. Can someone explain what's happened here?

    TIA

    Steven

    Looks like you were in the Mode of insulation of the Blend object - you could accidentally entered this mode without realizing it by double-clicking on the object of the mixture. Now when you draw a simple line, the mixture is getting redesigned because now he sees 3 trails blend instead of the 2 paths.

    I hope this helps.
