Datasocket bug in Win2K - constantly updated

= OVERVIEW =.

I have a simple Datasocket system which produces a very strange problem on Win2K

After a variable duration (from 30 seconds to 30 minutes), the player datasocket simply stop receiving updates of the writer.

The system features a base Writer DS and DS player that communicate over the DS server localhost. I've included the reader and the writer screws for your tests. In addition, it seems to be easier to reproduce if the screws are compiled into executable files. I've included the executables for the tests. The problem is reproducible when the 'reader' is actually a C++ (using Measurement Studio) program which is integrated into an OCX component (not included).

NOTE: This bug doesn't seem to be reproducible under WinNT.

I spent a lot of time this system... with no luck debugging. I've narrowed it down so that it is very reproducible. Just run the Datasocket server and the two clips EXEs on Win2K (Professional) and wait a while... eventually, you will see the Player stops to get updates.

= DESCRIPTION OF THE SYSTEM =.

The writer of the DS to connect to the DS server in 'write' mode and sends an array of doubles. An "attribute" property is specified as another array of doubles. The writer then updates the connection. The two paintings are supposed to represent the values and timestamps.

The DS drive connects in mode 'reading-auto-update. He is waiting for an update and then reads the table and its "table of attributes.

Take a look at the examples attached... they are very simple.

= PROBLEM =.

The problem is reproducible on Win2K machines.

After a variable period of time (usually no more than 10 minutes) the single drive ceases to receive updates. The DS connection is reported as "Active: connected" and the status is 'ConnectionActive '.

= NOTE =.

I use LV6.02 and the latest version of Datasockets 4.0 (370).

2 screws are in the same delivery system: the User Interface.

On the PC power management is set to "always on" and the power to save them all, functions of sleep, screensavers, etc are disabled.

I use the 'old' datasockets screw (open connection. read/write double vector, close, etc.). I realize that the "bug" I'm reports could in fact be fixed if I used the new Datasocket screws that come with LV6i, but we really don't want to use these screws we find the old screws better because:

1. the older screws seem to be faster to the writing of the major vectors. We discovered this through tests.

2. reliability of maintaining connections. The older screw seem to be more to the maintenance of the connections.

3. the new screws have difficulties getting the items appear (and with the appropriate icon) in the window "Browse measurement data.

No other significant network activity is seen when this bug occurs. It seems to happen randomly.

  • MSU files are constantly updated

    Since may, on a PC with Vista and one with Windows 7, Windows Update is not updated even after 24 hours to research.

    My update agent has the latest version 7.6.7600.256. The necessary dll files have been re-recorded with an appropriate script. Removal of C:\Windows\SoftwareDistribution\Download etc did not help.

    There are various recommendations to install a couple of individuals updated system preparation tool, or manually before running automatic wu again. But on the PC, the msu files are constantly updated .

    How to get out of the trap?

    Finally I did the job.

    1 free up memory extra RAM by temporarily closing Sophos SAVservice

    2 stop wuauserv every time before you begin the next msu file

    3. install manually:

    • Windows6. 0-KB3140410-x 86.msu
    • Windows6. 0-KB3153199-x 86.msu
    • Windows6. 0-KB3161949-x 86.msu
    • Windows6. 0-KB3164033-x 86.msu
    • Windows6. 0-KB3139852-x 86.msu

    4. Subsequently, normal search updates brought upward within 45 minutes.

  • Constantly update screen

    I have a game that I'm writing and I want to make the screen constantly updated. I tried to use a while loop and call invalidate on the screen, but it does not draw anything. I can do if I call the invalidate to a key event to draw. I use the Simulator IDE and storm 4.7. Any help is appreciated.

    @RexDoug - probably applicable in this case, but can clarify you your message please.

    In the first paragraph, you say that the invalidate() is called with the event Thread because it is part of a key event, but on the second, you say that it should be queued to get in an event Thread process?

    Also, I don't think invalidate() has the thread of events - I think I have the code that invokes it directly (for a form) to a background Thread.  In my view, there is no treatment, it initiates just repainted at a later stage.  But that's just my experience and I could be wrong.

  • The Mediam player constantly updated from Windows: unnecessary files, creating unnecessary playlists and double and no way to stop the updates.

    Upgrading to windows 7 and unfortunately found with the latest version of media player. Here is a short list of what I need fixed (because I can't come back until I have decide of windows 7 is just as useless):

    1 player constantly updates whenever the program is opened (not even try to play a song or whatever it is, it starts). This creates files garbage off all, I mean ALL media files in all my shows. the first open I found myself with 2 700 new titles prior to this, all were games or software sound effects. I tried all the options of the user for what this is about updating and stop anything that even resembled an auto-update feature (although nothing seemed really appropriate).

    2. the update also adds auto-playlists, but also of new playlists 'trash' to my normal playlist section who have no related audio files or some effects files above game/software.

    3. it adds not only my multimedia player, but apparently my global media 'profile,' like the first time I went to update my itunes started all these files garbage pulling himself into thinking they were WMA to convert.

    4. the mini player mode needs an option "opacity" so it doesn't go away in circles when I don't have my mouse hovering over him.

    5. attach your download links for skins/visualizations, etc. I used the direct link for something that might not have the opacity of the skin problems regular mini Player and ended up with a file that has frozen on the media player. After using System Restore, I tried another skin on the direct link is a media player and got the same result. I gave a third try (after restoring again) and got the same result. Nice link/beta test...

    Moreover, to use this computer to the direct sound, so I need a little my files, clean, organized, and without all the garbage you are dull upgtade is cramming my complete with hard drive. Thank you...

    Thank you for visiting the Microsoft answers Site.

    When you start Windows Media Player for the first time, it automatically searches certain default folders in the library music, pictures, videos and recorded TV.  If you add or remove files from these libraries, the Player automatically updates its available media files.

  • Space to work constantly updated, nested scenario & MergeWorkspace

    Hello

    I use Oracle WorkspaceManager oracle version: Oracle Database 10g Enterprise Edition Release 10.2.0.4.0 - 64 bit

    1 / I creates a workspace with the isRefreshed flag is set to true.
    2 / I immediately create a backup point A.
    3 / I insert a row into a table with version.
    4 / create savepoint B.
    4 / exec dbms_wm.setdiffversions ('workspace', 'A', 'space', 'B')
    5 / querying the view of diff should show me 3 rows.
    DiffBase and workspace, a lines would have wmDiffCode: NO (not existing)
    workspace, row B would be wmDiffCode: I (insert)

    All is well until now.

    5 / I merge the LIVE workspace
    6. / I query the view of diff again:
    DiffBase and workspace, a lines would have wmDiffCode: NC (not changed)
    workspace, row B would be wmDiffCode: I (insert)

    I confirm that the step 6. / wmDiffCode Watch: DON'T, if I disable continuous update.

    Can someone tell me why the wmDiffCode change in NC in this scenario? I thought that creating a backup point records a snapshot of the workspace (including display Different States) which are not editable by the refresh operations on the workspace, it seems that this statement is false.

    Any ideas appreciated.

    Thank you

    Hello

    What is expected. The code indicates that the line does not currently exist from this version/point of backup. However, when the line is merged in the DIRECT workspace and due to the fact that the child workspace is being constantly updated, this new line will become visible A backup point. Any change in the LIVE will automatically update workspaces child (including points of previous backup) up to the point where each line is changed. Given that the line is now visible from the backup point A, code has changed since the NO and NC.

    When the workspace is not be continuously updated and fusion in the DIRECT workspace doesn't cause any changes at the point of a record, so the line is non-existent.

    Kind regards
    Ben

  • Why don't we not constantly update?

    We run a business on the internet very nice and let 5 computers work hard however we continue to be updated almost every week. It became a chore to use Firefox. When we started to use Firefox, years ago, that we could get an update 2 times a year, now it seems that 2 times a month. Please let us know why and if there is something we can do to change that. Update and unnecessary changes is very costly for our business and if she continues to make us perhaps change browsers. We love Firefox but updates must stop be so frequent. We do not have the time to update or do we not want any computer update unless someone watching him. We don't want automated updates. Update was the worst when you have made all of the unnecessary changes. It took me all day to all 5 computers to look alike so everyone can use anywhere they work. Please consider yourself a browser at the top of the page and not a fly by night. It is a professional company, so please act like him, walk like and this u-turn. I wonder if someone from Microsoft has begun to help you?

    New versions are released every 6 weeks for over 3 years now. There are several versions of "chemspill" both Firefox 32 and 33, since early September, to address the issues of security or because of the accident of bugs to a small part of the base installation.

    I have not tried running your code, but here are some possible solutions:

    1. There is a primitive to write the value of a control by index (added in ~ 2013). This is designed to be used others live too and should work like a local.
    2. You can send data using another way (like a queue, etc.).
    3. Use the Ctl Val.Set method.
    4. Do not use a chart. Use a chart and manage the buffer yourself. You can find some examples if you're looking for graph XY.
