Problems with GUI under Windows-NT

Hi friends,
I've created a Java-Application which works fine under Windows 2000, Windows XP, Linux and Solaris.
The only problem I have is with Windows NT.
When the application starts, the window will open but doesn't display any content. The application is
working (as I can use keybord-input, keybord-shortcuts and so on), but no display besides an empty
window...
I tried different Look&Feels, but no change....
Do you have any ideas what could be wrong?
Thanks a lot,
Chris
P.S.: JDK is 1.4.2_04

Try adding the argument -Dsun.java2d.noddraw=true on the launcher.

Is there a problem with JFrame and window listeners?

As the subject implies, i'm having a problem with my JFrame window and the window listeners. I believe i have implemented it properly (i copied it from another class that works). Anyway, none of the events are caught and i'm not sure why. Here's the code

}anyone know whats wrong?

It turned out that my ide was running the old jar and not updating it, so no matter what code i added, it wasn't being seen. Everything should be fine now.

Problems with ViaVoice under Leopard, especially key mapping problems

ViaVoice's behavior has changed considerably under Leopard. First I will discuss the key mapping problem, since I'm eagerly looking for an answer to this problem. At the end of this post, I will voice some of the other problems I've experienced for those who may be interested. The key mapping problem may be specific to the fact that I use a foreign keyboard with a US version of ViaVoice.
INTRO:
I have used ViaVoice on my Mac for years, more or less without problems (ViaVoice's bugginess is notorious).
Those who know ViaVoice will know that one has two general options for dictation. One can dictate into ViaVoice's so-called SpeakPad, which allows special formatting, editing and dictation error correction within the dictated text, or one can dictate into "external" software such as Microsoft Word, in which case ViaVoice just sends a string of characters to that software. SpeakPad appears to make strong use of the operating system's built-in functionality for character formatting, document formatting, etc.
*MY PROBLEM*
I have a German keyboard on my PowerBook, yet dictate in US English. When I dictated into SpeakPad under Tiger, all characters appeared correctly. However, when I dictated into Microsoft Word using Tiger, I had to switch the keyboard mapping from German to US to get all characters (that means including the characters that are located at different positions on a German keyboard than they are on a US keyboard such as y, z, apostrophes and parentheses) to appear correctly.
Under Leopard, things have changed. Now it doesn't matter whether I dictate into SpeakPad or Word; the results are the same and many characters do not appear correctly.
If set to a German keyboard, y and z appear as expected. To name a few irregularities:
"(" appears as ")"
")" appears as "="
apostrophes appear as "#" and
";" appears as ","
If set to a US keyboard, y and z are interchanged. "(" and ")" appear as expected. Apostrophes appear as "\" and ";" appears as ","
By comparison, if typed (as opposed to dictated, as in the examples above) "correctly" (i.e. based on the letters printed on the keyboard) on a German keyboard set to imitate a US keyboard:
y and z are interchanged
apostrophes appear as "|"
"(" appears as "*"
")" appears as "(" and
";" appears as the symbol for "less than"
Since I don't have a US keyboard, I can't say how it would behave if set to imitate a German keyboard, i.e. if there's a correlation to the results I get when I dictate.
Since I was previously able to dictate correctly into SpeakPad by setting the keyboard to "German" and into Word by setting the keyboard to "US," I presume that this is a problem in Leopard, not ViaVoice.
*OTHER PROBLEMS WITH VIAVOICE UNDER LEOPARD*
In addition to the aforementioned key mapping problems (that may be specific to those of us with foreign keyboards), ViaVoice appears to have lost considerable functionality in Leopard. I cannot access SpeakPad's Preferences and the correction window. Moreover, the traffic-light like window buttons have disappeared from the VoiceCenter (although they work if you click where they should be). SetupAssistent appears to function.
I've written to Nuance about these problems, but have little hope that they will invest the time in producing a patch since they haven't released any updates since 2003.

Thrums1,
I've never had to "register" ViaVoice after updating the system. I thus suspect you haven't fully followed my above, three-step advice (particularly step 3).
1) Reinstall ViaVoice from CD.
2) Update to the latest version (using the patch downloadable from Nuance's website).
3) Replace the “temp” and “users” folders (in the "ViaVoice" folder at the upper level of your home directory) by a previous copy thereof. When I say previous copy, I mean a copy from when ViaVoice was still working properly, e.g. a copy from when it was running under Tiger.
As I said, I've gotten ViaVoice to survive several system updates by following the above steps. To my knowledge, the last step is critical since it saves you from having to reconfigure ViaVoice under the new operating system (in this case Leopard). I suspect that ViaVoice is crashing on your system because it's trying to start some module of the SetUpAssistant that is incompatible with Leopard (as many are). If you instead use old copies of the "temp" and "users" folders (from the previous system), then ViaVoice doesn't have to go through the initial "registration" process; ViaVoice doesn't need the SetUpAssistant; and all is (more or less) fine.
Good luck!
BTW, to my knowledge, Dictate only runs on Intel Macs. It thus won't run on a G4 iBook, just as it won't run on my PowerBook G4.

Problem with clob_write under client 9.2.0.6: UnsatisfiedLinkError

Hi all,
I'm running Oracle client 9.2.0.4 on Windows XP and Java 1.4.1_3.
Writing or reading clob's works pretty well.
As i tried to update to Oracle client 9.2.0.6, i got the error
Communication failed: java.lang.UnsatisfiedLinkError: clob_write when i tried to write a clob. The same error appears when i tried to read a clob.
Is there a specific problem with clobs under this client?
All other JDBC operations work as good as before.
Thanks.

Here is another hint.
In your classpath, use the jdbc driver that's under your oracle installation to which you are trying to connect to (ie, <ORACLE_HOME>\ora92\jdbc\lib\ojdbc14.jar).
I had the same problem in 9.2.0.6 and its gone when I replaced the ojdbc14.jar. I copied the ..\ora92\jdbc\lib\ojdbc14.jar to my java client program's classpath, and ran the java client without getting the UnsatisfiedLinkError.
It looks like the ocijdbc9.dll under ora92\bin has to match correctly with the jdbc drivers you would be using. I got this idea from this link:
http://episteme.arstechnica.com/groupee/forums/a/tpc/f/6330927813/m/705001068631/inc/-1
Hope this helps.

Problem with shares on Windows 2003R2 server from a Windows 8.1 PC

I'm having problem with shares on Windows 2003R2 server from a Windows 8.1 PC. It times out when I try to copy a file from my PC to the server and I get an error message saying "There is a problem accessing network drive W:\. Make sure you are
connected to the network and try again."
I have no problem copying files from the server to the PC.
Any ideas?

Hi,
How about your problem now? Have you test other machine also installed Windows 8.1? Did they have this problem?
To diagnose this problem, firstly, please check Windows 2003R2 firewall settings, also can disable firewall temporarilly for test.
Secondly, try to use Network Monitor to capture network communication package for test.

Problem with touchpad and Windows 8.1. Acer Aspire E5-511

I bought an Acer Aspire E5-511, but I have problem with touchpad and Windows 8.1.The touchpad (Synaptics) is not working with Windows 8.1 x64, but it works fine with Windows 7 x64 and Windows 8 x64.When I install Windows 8.1 and have to choose” language to install” I can’t choose anything with the touchpad. I should plug in my mouse to continue. I doesn’t work even when it’s fully installed and with latest driver (available only for win 8.1 x64) from Acer’s website. I tried with an older driver, but had no success. I updated BIOS, but it doesn’t work again. In hardware IDS in device manager it shows HID\… not ACPI\… (like win 7/8). Fn+F7 doesn’t help.When I try to install Windows7/8 the touchpad is working properly at the beginning (I can choose ”language to install”, “Time and currency format”… and the touchpad works after install even without driver).

SOLUTION So guys after deep research and troubleshooting I found that you need to keep notice of a few things at time of installation: Installation Mode: UEFI (only)- LEGACY would create touchpad issues. after installation of windows just follow the driver installation hierarchy 1.Intel NB_Chipset_M Baytrail-M 2.Intel I/O Driver then rest of the crap. Note:After doing all this make sure your touchpad is active >> Fn+F7 Just wished if this solution came from an acer executive , the world would have been a better place , but anyways this is what community is for. Enjoy everyone

Windows 8.1 Problem with games from windows store.

I've got a problem with games from windows store. The installation is going well without any problems, however when I try to open it it's loading and then it turns off. The same problem happens when I try to use Games for Windows. I've use a sfc scan and
it shows some errors but unfortunately it cannot fix them. Should I share the CBS log or find the solution somewhere else? I hope you help, best regards.

Hi,
According to my experience, the problem like store game app open failed probably caused by hardware driver. such as Audio and Graphic driver. So, first of all, please try to reinstall these two driver to fix this problem for test.
In addition, for SFC scan failed problem, it can be caused by many reasons, I would suggest you use another command to fix your system for test.
Dism /Online /Cleanup-Image /ScanHealth
Also you can test SFC command in Windows 8.1 safe mode.
Thirdly, if problem persists, please check Event Viewer, generally speaking, it would record the app open failed events.

Problem with the Finder window in Chrome

Hello,
I have a problem with my finder window in Chrome.
Since the window isn't a separate window anymore, but stuck to the top of the webpage, my finder window is too big. I can't read the "Cancel" or "Send" (I have no idea what's supposed to be there in English but I assume it's something like "send" and "cancel") buttons. I have provided some images of the problem, even if I make the Chrome window as small as possible, the finder window still is too big for my screen. I can resize the finder window from lest to right, but not up or down, which is extremely irritating for me.
If anyone can help me how I can solve this problem.
Thanks!

I found the solution on another thread...Here it is.
"I was having the same problem. I found a way to make it smaller. First, I opened chrome and clicked the green button on the window to make chrome go into full screen. Then I tried to save a file to make the finder window open in chrome. When it opened in full screen I could see the bottom of the window so I resized it to make it a little smaller. Once I did this it remembered the size so now I can access the bottom buttons when I take it out of full screen mode. Hope this helps."
Worked like a charm!

Problems with over/under absorption on production cost centers - GBB AUI

Hi,
I have a problem with over/under absorption on production cost centers after month end closing.
We are using material ledger CKMLCP and actual activity rates from direct cost centers are settled directly to products using GBB AUI account determination.
Unfortunately from time to time there appears a significant balance on production cost centers after running CKMLCP. What might be the reason? I have analysed line items on cost centers but cannot find any answers.
We are using assignment of cost elements to particular activity types (function splitting), and I have checked that all cost elements are assigned to proper activity types.
Best regards,
Karol

Hi,
DP90 is used for Resource related billing, is broad term basically when you performing service that time you have to raise billing on the basis of resources which you had spend for perticular service
DP90 is run on the basis of DYNAMIC ITEM PROCESSOR,
http://help.sap.com/saphelp_di471/helpdata/en/59/54fc37004d0a1ee10000009b38f8cf/frameset.htm
I will tell you one process from the prspective of CS module
Create notification >> Create service order >> Confirm service order >> Resource releted billing (genrates sales document) >> Invoice to customer with refrance to sales document.
Now here DP90 is used to determine material,IN SALES DOCUMENT because CS module don't have billing feature as like SD Billing.
In CS module activities/Operation,but in SD module we speciefy material codes
So DIP determines XYZ activity/operation is ABC material in SD

Adobe reader XI: doule sided print problem with network printer (windows 8 pro)

Hi, I'm facing a problem with my old printer, the xerox phaser 3160n. It was connected to my notebook through network connection, and everything works well with Adobe X /Win 7 OS (including the double side print, of course) last month, I have upgraded my NB to windows 8 with clean install
clean install my printer driver for windows 8 too, and Adobe reader XI was also downloaded through official website.
However, since I was about to use double sided print in Adobe reader XI (11.00.02) it couldn't obey the order, but just print one side as usual
I have checked the "option" of my printer, and it was correctly set to "double-sided print". I have tried word 2013 to open the same pdf, and choose the same "double-sided print" and it works perfectly.
Is this problem a bug? and would it be corrected in the next update version??
(I remeber I've saw a similar issue too, with network printer, but I couldn't find it)
Thanks!!!

Hi,
Meanwhile, after insatlling the latest driver for printer from the manufacture website, restart the spooler service as a test.
Start > Run > cmd and type "net stop spooler" after that "net start spooler" or start > run > service.msc and restart it over the GUI.
Run Printer Troubleshootor under Action Center\Troubleshooting\Programs\Printer, and check if it helps.
And yes, the manufacture should have more sence about the printer, it's recommended to contact them.

Design Problem with GUI sub vi

in general, I would like to separate the GUI from the data, but I get
a problem with this design approach in LabView:
I often have sub VIs that are supposed to control something.
Therefore, these VIs consist of a control loop. A GUI window should
show the regulation process (showing how the tracking error is
hopefully approaching zero etc.). As I said, this GUI should be a
separate VI (separate from the control loop VI). Since the GUI has to
be updated on each sample, it is clear that the GUI VI should be
inside the control loop, and therefore, it should be a sub VI of the
control loop VI.
Now, the problem is that the control loop VI itsself is a sub VI
because the whole regulation is just a subsystem of the whole program
(The main VI doesn't have a GUI, but first starts a (GUI) input mask
for the same reason: separate the GUI from the rest).
But back to the GUI VI inside the control loop. I must check the 'Show
Front Panel When Called' option. But I can't check the 'Close
Afterwards if Originally Closed' option since the GUI VI would appear
and disappear in the control loop - according to the loop's sample
rate. However, if I don't check the 'Close Afterwards if Originally
Closed' option then the GUI VI will continue to show, even after the
control process is finished.
So in other words: I need the possiblity to close the GUI VI
programatically, after the control process is finished.
Any ideas?

Hi tmh,
thanks for your answer

I try to avoid globals. Now, suppose I had multiple unrelated control
loops. I had to suppose a global variable for each of these
subsystems. I already use globals for the GPIB device IDs. I wouldn't
like more.

But if I split the GUI: How can I view them simultaneously? The user
must see input and output simultaneously, in one window.

Your approach sounds interesting. Is there a sample for this
architecture in the examples?
Anyway, I have to point out that I have several unrelated GUI windows
in my application. There is no notion of a main GUI in my application.
The control loop is just one feature of my application, so it doesn't
make sense to use the control GUI as the top-level VI. At application
startup a user input form is displayed (it also has some sort of menu
selection). But even this window can't be toplevel since it provides
an Option radio button (that shows and hides controls, accordingly) a
CONTINUE button, and a STOP button which implies that the input
form.vi must be
in a loop.
The problem is that I can't send messages to windows in LabView as I
am used to in Win32/VC++.

Problem with Java and Windows (Mainly Vista and UAC)

Hi all,
I am having a problem with a program that I've devoloped. The program itself is packaged as a jar and I plan to deploy it across multiple platforms eventually however right now i am only concerned about windows based systems. I have made an installer for a windows baised systems using NSIS to install the software files. I made the installer as I need several java packages to be installed so the program would work (JAI, J3D, JAI ImageIO) and I also require the program to have fileassociations on windows.
I know that this is not what java is about, however the majority of the users will be on windows baised systems so I've decided that OS specific installers is the best option.
During the process I have noticed that there are several key problem with java for this type of application!
The first issue that I have come across is getting file associations to work on java. As a .jar is not an excutable it is not possible to directly associate a filetype with it in java so to overcome this I currently run the program from a .bat files and also the program requires large memory so this also allows me to run the program with -xmx. The batch file that I use is :
<code>
cd PATH TO PROGRAM
start javaw -Dsun.java2d.noddraw=true -Xmn100M -Xms500M -Xmx1000M -jar "PATH TO PROGRAM\program.jar" %1 -vram 134217728
pause;
</code>
Ok so all this appears to work fine and allows windows to have file associations and start the program and thats all works perfectly but this is a non-ideal solution. Has anyone got any advice on improving this?
The next problem that I have appears to be a problem with Vista and UAC (user access control). When a user installs the program and installs the program into the program files directory I found that the program did not work and kept saying that I did not have access to the files in the current directory. This is a problem as I read and write settings files during program execution.
On a Vista system UAC prevents file write operations into the Program Files directory unless the program has requested elevated status even if the user is a full administrator. The probem is that there appears to be no real way to achieve this under java that I'm aware of...
Has anyone else had this probem and has a suitable solution?
Any advice on these issues would realy be appricated.
Regards
Joey

Ok so i've kinda found a solution, its not ideal but its very good. I found this program called Elevate
A link to the site I got it was
http://www.wintellect.com/cs/blogs/jrobbins/archive/2007/03/27/elevate-a-process-at-the-command-line-in-vista.aspx
This program allows you start java with a UAC dialog for high access using
Elevate java -jar myjar.jar
This then allows you to have full access using java... I guess it could be dangerous but it does the job.

Acrobat reader X with thunderbird under windows 2008 server

Hi,
i use acrobat reader X under windows 2008 R2 . My Mailclient is thunderbird.
I get an error when trying to send an E-Mail. "Acrobat could not get a connection to your e-mail programm".
I defined thunderbrid as the standard mailprogramm under START->CONTROLPANEL->STANDARD-PROGRAMMS
I already tried to google the solution, but the only one i found was for Windows VISTA and Windows 7. There, you have not only to define the STANDARDPROGRAMM, you either need to make a change on "default programms and computerstandards" which is missing in windows 2008 R2
Can anyone please tell me how to use acrobat with thunderbrid in a windows 2008 environment????
Thank you

Hi Michael,
sorry for using the wrong forum. I'll post my question to the Reader board ...
To answer your question. That was my idea too, but it is not possible to copy a whole profile. They are a lot of other problems if you do that. I didn't find the settings only. may it would be enough to copy the settings for the reader.
Best Regards,
Markus
