Synopsis:
Sometimes (not everytime!) when I wakeup my PC from hibernation and MediaPortal is started (after automatically entering hibernation mode via PowerScheduler) I only get a Windows error message after the booting/wakeup sequence:

MP-Bug.png


On the second system using the MCE skin it's the file "fontSVT_12.png.xml" in folder "C:\Program Files\Team MediaPortal\MediaPortal\skin\mce\fonts".

MediaPortal IS started in the background, however - while only this message window is visible in front of a black screen, MediaPortal can invisibly start XMLTV or record TV shows, it even goes into hibernation again after 10 minutes (that's my PowerScheduler setting). The log doesn't show any problem as well (see below), MP seems to load normally.
But when I press "OK", MediaPortal (still invisible) quits and the Windows desktop appears.
It's a clean Windows and MP installation with no other programs running in the background.

The MediaPortal log shows these entries [with my comments in brackets]:

    Hi Waltz,

    this bug still exists on my system (I upgraded to 0.1.0.7), but it seems that we are the only users with this problem. Does it still exist on your system, too?

    ciao,

    Yes, still the same problem :(
    I've updated to version 0.1.0.7 as well, and I've reinstalled Windows XP - didn't help at all :(

    Hi Waltz, hi eepunk,

    as everybody else seems to completely ignore our problem, I developed a workaround that seems to work...

    I think the problem is on the one hand that the files that cause the exception are deleted while there is still another open file handle for read access (possibly somewhere in GUIFont.cs).

    But on the other hand those files are newly created by mediaportal if they are deleted... So I did the following:

    I take care for the deletion of those files myself. To achieve this I need two steps:

    I start mediaportal after a fresh boot with a batch file. The first action in this batch file is to delete all files in c:\program files\team mediaportal\mediaportal\skin\mce\fonts
    The second action is to start mediaportal.exe

    But unfortunately the programs in the startup folder are not executed when windows wakes up from hibernation. So I had to install another program called StartOnWake (cf. http://www.showshifter.com/cgi-bin/ultimatebb.cgi?ubb=get_topic;f=2;t=003059)
    that provides startup functionality after a resume from hibernation. So I created a second batch file that deletes the content of the aforementioned folder and is started by StartOnWake.exe. You only have to make sure that StartOnWake calls the batch file before mediaportal accesses the files in this folder.

    I'm not sure if this solution is complete bullshit and works only by incident but what can I say ... At least it seems to work reliably this way... :wink:

    Maybe one of the developers can make a statement about my guesses and my workaround...

    Ciao,
    BartManson

    Hi BartManson,

    sorry, I have not checked this thread for a while since I had lost hope... I still cannot find this bug in the Mantis Bug Tracker; what do I have to do to get some developer's attention...?

    Have you tested 0.1.0.9? Did not have the time for an update.

    But I'm glad you have found a solution! :) Thank you very much, I'll test this workaround immediately.

    - Waltz

    I have tested this today - I cannot duplicate it after 10x Hibernations.
    Can you please detail the steps to duplicate this step by step for what you do to receive this error?
    Be very very specific about your configuration settings and the process you do to get this problem.

    Cheers

    DMAN

    Hi everybody,

    dman_lfc: The problem is that this error does IMHO not occur in a deterministic manner. Sometimes it occurs, sometimes not. The only thing I can say is that in most cases it does not occur. I think it is some kind of timing problem. As I mentioned in another post, I guess that a file handle to the XML file is still open (OS-wise) although it has already been closed by mp with the Close method. So, if mp tries to delete the file an exception is thrown. But that is just a guess.

    Nevertheless, here is my config:
    XP SP2
    NVIDIA GeForce 3 Ti 200 (latest drivers. Have to check the version number home ... ;-)
    PVR350 (latest drivers. Have to check the version number home ... ;-)
    WinTV PCI (for Nxtvepg) w/ BTWinCap driver
    .NET 1.1
    No virus scan software
    PIII 900
    TVTool 9.7 (no black border on GeForce3 tv-out)
    384MB RAM
    VIA APOLLO133 Chipset
    Medion MoBo MD3000 (not quite sure)
    Hauppauge IR-Remote tool
    MP 0.1.0.8 (error occured with previous versions, too)

    Is this sufficient?

    Waltz: The workaround from my last post didn't work reliably. In the meantime I wrote a small script in VBScript that is executed by startonwake.exe. It executes the following commands:
    1. Kill Mediaportal (tskill mediaportal.exe)
    2. Close TVTool (not relevant if you don't have tvtool. TVtools doesn't work properly after hibernate)
    3. Start TVTool (-> black border disappears :))
    4. Start Mediaportal

    Since I changed this everything works like a charm ...

    I can post the .vbs file and the corresponding startonwake.txt file from home if you are interested.

    Ciao,
    BartManson

    dman_lfc:
    Well, I think I've already covered everything in my bug description. I don't do anything very special for causing this error to appear: I just let MP/Powerscheduler hibernate the system automatically (does so after 10 minutes) and let it wake up again (via task scheduler or manually). That's all. The error does not occur everytime I do this, but in the majority of cases it does. :(

    I've tried many different versions of MediaPortal and use only standard plugins (Powerscheduler, MyTetris, MyPrograms...) and skins (BlueTwo, MCE). It's a fresh Windows XP installation with newest drivers and there's absolutely nothing running in the background (not even a firewall or virus scanner). I don't use exotic hardware (Athlon XP, GeForce FX 5200, SoundBlaster Live! and WinTV PVR-150 MCE - not that special I think) and everything else works like a charm.

    My MP settings are mostly default. I add my TV card, configure XMLTV, add some games to "MyPrograms" - nothing special here as well. Using VMR9, fullscreen @ 800x600 - well, what do you have to know? :)

    We'd be thankful for any kind of help.

    Thanks BartManson, I'll do this by myself with the tool pskill.exe (for killing the MP process), a simple batch file is enough for this.

    I've tried deleting the .xml files causing the error, but MP would not start without these; well, I'll make a clean installation of the newest MP version next week and use your new workaround then. This will make the startup process much slower, though...

    Yes, I think you are right about this possibly being a Windows 10 problem. Mostly because I didn't touch MP or it's settings, it just got broken while I was away. I read somewhere (unfortunately I don't have a link to it right now) that the latest major update to Windows 10, Creators Update, removed some parts of windows file sharing...
