Blank display panel problem

I have an application which collects data from several sources, displays the data on multiple panels, and writes the data to disk. This program also uses the CIVIC Web Server. The program has run correctly for days and even weeks.  Eventually the display panels all go blank.  The panels are still there but contain only white space.  The collection and writing of data to disk, however, continues.  When the program is stopped (from the task bar or task manager) and restarted, it performs normally again.
Has anyone else seen this kind of behavior?  I suspect that it might have something to do with the web server, but I have another very similar program running on a different PC also using the web server.  This program does not have the blank screen problem.  
Thanjs for any light you can shed on this.

Hello Judy -
I recently saw this in a CVI program I had written, and in my case, the cause was a memory leak in my program.  If you open task manager when you see this white screen, how much memory is the CVI application using?? 
I would also make sure you've enabled extended debugging on your development machine in debug mode, which should show you any memory leaks you may have.  Just enable extended debugging through the Options»Build Options dialog, and then run your program under the debugger.  You should allow the program to exit normally.  If the Resource Tracking window then displays, it is an indication of resources that need to be cleaned up.  For more information, refer to this document.

  • Font Display Panel Problems

    I was reading an online article about using iWeb
    http://www.mymac.com/showarticle.php?id=3047
    and there is a screen shot of the font display panel
    This is the panel many applications use to allow the user to adjust the fonts. If you open TextEdit and go to Format/Font/Show Font the Font Panel will appear.
    As you can see in the iWeb article the screen shot shows recently used fonts. The fonts show how they actually appear or they are preview. When I bring up iWeb o TextEdit I don't see that preview. If I select the Gear icon in the lower left corner I can turn on Show Preview but this just brings up a header show what a selected font looks like. The fonts in the list don't change.
    There seems to be a problem with my Recently Used and Favorite lists. There are a few fonts in my list but they are not grouped together. There are blank rows listed between the shown fonts. However if I click in the blank area a font is selected and if you have any text selected in the document it will change that text.
    If I choose a new font for a TextEdit document that font never shows up in the Recently Used list.
    Is there a preference file for this panel? It appears my font display panel is not working correctly.
    Are others having these issues?
    Thanks

    I have an iBook running 10.4.11 and the recently used collections gets updated correctly. However when adding a font to the the Favorites collection there are blank rows between the fonts I've added. Also if you select the font type and not the specific font such as the bold, or regular it doesn't copy all of them.
    Also, unlike in Leopard when you select the Recently Used collection you see what the font looks like show in the list irrespective if the preview panel is activated. Looks like for Leopard the font display panel was changed or not tested thoroughly.

  • Display Panel problem

    I have just finished installing the ENVY 5530 printer, and have successfully managed to print documents, but the display screen shows nothing but the language information. No other icons are showing according to the panel parts description. How do I enable the display screen to show all the icons?

  • E71x blank display, backlight keeps blinking on an...

    I've had my E71x for a week and have not had any problems until now.  While trying to power the phone on, all I get is a blank display and then the backlight just blinks on and off. 
    The battery was fully charged when I turned the phone off.  I've tried removing the battery and putting it back in.  I've also tried the reset by holding the green call button and 3*.  Nothing has worked. 
    Thanks in advance

  • HP laserjet 4200 - display panel is off

    After changing the printer cartidge, the error 49 FF01 continued to appear on the display panel so, as suggested on the internet, I turned the power off and then turned it on again. The problem was, after turning the power back on, the display panel is completly off and now the printer appears as offline on my computer. Can anyone help me please? Thanks.

    So what is the average expected wait time for a response here?  My printer has been sitting in pieces on the floor for 12 days now, with no response with even a hint of a suggestion from anyone.  I'm guessing at this point I should just write this website off as a loss and try and find some other help forum?

  • HP Photosmart c309 display panel

    My HP Photosmart c309 printer display panel does not show the menu it only shows the hpwith a circle around it and the power button blinks on and off.  I can't do anything using the menu display on the printer.  I have tried uninstall and reinstall, turning the printer on and off, new ink but nothing works.

    Please try to unplug all the connection to the printers such as power adapter, USB cable.
    Let the printer stand alone about 10 minutes without any connection.
    After 10 minutes, connect with the power and switch on the unit.

  • Can I place a 13" retina display panel into my 2011 MBP?

    I was wondering (moreso wishing and hoping) if it's possible to have my 2011 MBP display panel replaced with the recent 13" retina display panel. My 2011 MBP is just out of warranty and its display panel has developed a green line issue that seems too common among MBP displays.
    Thanks!

    The best option would be to take this to Apple and pay for it to be fixed. The display will be expensive to fix, so if you feel you can, purchasing a replacement from eBay or somewhere online would be possible. You can not fit a Retina display on as the hings and connectors are different, and even if they were not, the firmware and drivers your Mac will have (and continue to have as the model number tells the system you should have a standard display) can not drive the higher resolution efficiently. This would lead to performance and battery issues.
    Consider buying a desktop stand and display for your Mac as well and use the built in display only when necessary. Small problems with LCDs usually develop into worse situations quickly.
    Good luck!

  • Facing "Display Flickering" problem with my 15" macbook pro(A1286)while swapping the desktops and closing the tabs.....need help...reply soon

    Suggest Solution for this Display Flickering problem ....

    Hi, I read the post about calibration and I probably do that a little too often TBH! As I get so little time out the battery and mainly use my MBP on my lap, usually with the power supply near by, it gets charged to full, run to empty to the point of sleep, or sometimes it even cuts out and then is recharged to full again, so I really think it's new battery time. I've seen non Apple Official ones for between £35 and £65 that have 3 year warranties and state they are around 5200mh but am unsure due to reviews.
    Later...
    Anyway's I have now ordered a non Apple replacement from Amazon for about £35 and it has several good reviews and 4.5 out of 5 stars so I'll see if it works and report back. If it doesn't I'll send it back and get the Official Apple one.

    Pictures would help. A good way to do this is to post them to a free photo sharing site like Flickr and then post a link.
    Also, you are in the original MBP section, and I think you need to post your question in the newer MBP section:

  • Retina display wakes in high resolution / breaks Displays panel

    Hi all,
    Yesterday I used my new retina MBP with an Apple TV, mirroring its screen up on the AppleTV for a presentation. Since then, whenever I wake the MBP (I have its Energy Saver settings set to sleep the display but not the computer after a time), it wakes in super high res with tiny tiny tiny text (this may be 2880 x 1800 but I can't tell, but it's higher res than the highest setting the Display panel offers you). 
    Then, because I want to reset it to something readable, I open the Displays panel, and click Best for Retina or such, and it doesn't change. None of the resolution settings do anything. The Display panel is not entirely broken, because the GUI functions, as in, highlighting different options I choose, but there's no reaction.
    To fix it, I've found I can go into the menu bar icon (rectangle with triangle under it, the AirPlay icon), set the MBP to Airplay mirror to itself (which strikes me as an odd option to have available).  This changes the screen to something pretty low res with letterboxing at top and bottom, and asks me for a Airplay password for my own system. I say Cancel, and then my Displays panel works again, and I can select Best for Retina.
    Any tips? Seems like a bug.

  • ADF/Swing: changing iterator in runtime before displaying panel

    Is it possible ,before displaying panel, to change iterator name that was specified in design time and is placed in panel.pageDef xml file and this way display panel with different iterator than is in panel.pageDef file? If yes, is it posible display this way many panels in the same time?

    Hi,
    the iterator is referenced by the attribute binding. If you look at the Swing code then you see that the Swing widgets reference a named attribute binding in their model binding. To change the iterator you would need to access the ADF binding layer and change it there. which I haven't tried.
    The attribute binding references an iterator as a named reference, which means that changing the physical implementation - in theory - works if the same set of attributes are available.

  • ADF Swing - what happened to 'Display panel.java'

    When editing a for with embedded panels, in Jdev 10, when you right-click on the panel there is an option 'Display panel.java', that opens embedded panel for edit. I don't see this option in 11gTP3

    Sorry, wrong forum, this was supposed to be on 11g forum.
