Error control problem?

hey everyone, i wont lie this is a school lab, but for the lab i have all the prerequisits complete, this is more a question i was wondering about because i was trying to add a little extra to it. Well i want to add a while loop saying while the answer isn't this or this or this or this then say its an error and repeat the input, but instead every time i add something i get an error and it just doesn't seem to work? I've tryed a few different ways to do this, and it all works fine with out the while loop , and if i put just one condition into the while loop, but if i put more than one condition it doesn't seem to like it? Any help would be great, thank you all in advance
import java.lang.*;
import java.util.Scanner;
public class whats_the_math {
     public static void main (String args[])
          Scanner in = new Scanner (System.in);
          String mathNumS;
          char mathNum;
               System.out.println("\nEnter one of these to see what does what!\n+, -, *, /, %\n\nEnter Exit to Finish =]");
               mathNumS = in.nextLine();
               mathNum = mathNumS.charAt(0);
//This is what im having problems with gettnig to work, the multiple conditions in the While loop. With just one condition it works fine but i cant seem to ge tit to work
// With multiple loops, if anyone could point me to some info or lend a hand that would be great because all the stuff ive foudn for while loops include just one condition
               while(mathNum != '+' || mathNum != '-' || mathNum != '*' || mathNum != '/' || mathNum != '%')
                    System.out.println("Error");
                    mathNumS = in.nextLine();
                    mathNum = mathNumS.charAt(0);
// This is where my problem stops, because with out it everything seems to work fine, so im guessing its seomthing to do with just this while loop i have because it doesnt
// seem to acknowledge the right answers and just gets stuck in the loop i guess?
                    switch(mathNum)
                         case '+':
                              System.out.println("This is Addition!\n");
                              break;
                         case '-':
                              System.out.println("This is Subtraction!\n");     
                              break;
                         case '*': case 'X':
                              System.out.println("This is multiplication!\n");
                              break;
                         case '/':
                              System.out.println("This is Division!\n");
                              break;
                         case '%':
                              System.out.println("This is modulus operation!\n");
                              break;
}

sorry the specific problem is, when i add the while loop, and when i add more conditions into it with the || operator, it doesnt work for me, say i put while(mathNum != '+' || mathNum != '-') and i use the switch statement afterwards like in my code i have posted, then it ignores even the right answer i put in, so its always giving me the error in the loop i added and not carrying on with the rest of the program. ill repost my code using the code button( sorry im new to the forum and didnt see it before) i commented around the part thats not working right aswell, thanks again

  • Error out problems with measuring frequency VI

    I am having some error out problems with measure frequency VI. The instructions is change error out from indicator to control but does not work. Anyone can help? The VI is attached
    Attachments:
    Measure Frequency VI error.vi ‏27 KB

    This VI does not have an error out. Obviously, you replaced a subVI that did have an error out with this one, otherwise you would not have been able to create this wire.
    Simply remove the wire or save the subVI with another name then modify it to have the error out that you are looking for.
    Hope that this helps,

  • User Account Control Problems with Premier Elements 7 32 bit in 64 Bit Windows 7

    I found User Account Control Problems in other forums but didn't see much in Premiere Elements, so I hope this helps others who may be having problems with 32 bit programs in a 64 bit computor. When I first got my 64 bit I didn't have problems.
    Back in February I bought a Quad Core Desktop with Windows 7 64 bit. Haven't been on the forum for 7 months since I wrote in regarding importing video with the Pyro AV Link (Premiere Elements Tips and Tricks). I was having problems importing video which started after March 28 sometime, as that was the last time I didn't have a problem importing VHS. Took me a few months off and on to find out what worked.
    I started uninstalling Windows updates and any programs I had installed back to that point in time. Checked after uninstalling each item. The capture screen would come up on a delayed basis but clicking on capture did nothing. Although no driver is required for IE1394 (so they say) I read where some people using the Legacy driver had fixed some problems, so I switched to the Legacy. Seemed to work great (for a few minutes).
    I had even uninstalled and reinstalled PE7 but no difference. Finally I noticed a shield in the PE7 Desktop icon. Thats weird. Never had that before. Just decided to show up after I had done all of the stuff I mentioned. Turns out at some point in time since I've had the computor Windows 7 decided to flag my 32 bit program as misusing the 64 bit system. User Account Control. I never bothered too much with UAC and just clicked on the yes box wen it popped up asking if I wanted this or that to take control of my computor. I tried using the minimum setting for safety reasons, and then finally turned User Account Control off. Bingo! PE7 capture works again and still working.
    While I am not recommending that people arbitrarily turn UAC off, this appeared to be my problem. I would recommed that they try turning it off before uninstallin a bunch of stuff. Having a restore point may or may not have been a fix for me. I think one of the Windows Updates caused the problem but I am not going to uninstall any more stuff at this point, I have not been back on the internet or installed any more updates in my desktop. I am going to use my laptop for internet and used the desktop for video.
    I am guessing this could be a problem for any 64 bit systems trying to use 32 bit programs. IE: XP,Vista,Windows 7 64 bit. In Vista there is also Data Execution Prevention (DEP) which you can turn on or off, supposedly to prevent misuse of memory (as I understand it), but Win7 either doesn't have it or I haven't found where it's located.
    Maybe this has been covered in the forum somewhere and I missed reading it. Hope I am not too confusing. Anyway, whatever feedback you guys have would be great.  

    John,
        Thanks for your answer, and I did check out the link you suggested. However, I have Windows 7 Home Premium as most people have I think, and the XP program was not available. I started with Vista and now have Win 7. I never could navigate around in XP anyway so am content to just leave User Account Control off.
        Interesting side note to turning UAC off is that my desktop seemed to be using more of the CPUs, where half of them were "Parked" as I wrote in also about 7 months ago when I 1st got my desktop. I am pleased to say that video processing seems to go quicker with UAC off. Have to observe things some more to confirm.
        I just thought if others were having problems after installing Windows Updates and leaving UAC off worked then they could possibly pinpoint a problem.

  • OWA error: A problem occurred while you were trying to use your mailbox (Exchannge 2010 SP3)

    Hi!
    I have several mailboxes that are was moved from Exchange 2007 to Exchange 2010.
    Sometimes occurs a problem: in OWA may appears error "A problem occurred while you were trying to use your mailbox" when selecting interface elements (such as "Options", "Public Folders",
    "Reminders"). After this error user cannot access to mailbox through OWA during 10 minutes. The error "A problem occurred while you were trying to use your mailbox" appears in top of browser window on any computers. This behavior is manifested
    in any browser, but it can not be associated with any particular event.
    Access to mailbox through Outlook or through mobile devices (ActiveSync) continues to work fine in this time.
    The errors in Application log on Client Access Server is absent (including error with EventID 9646). ExBPA is not showing anything specific to that error message. Test of OWA connectivity working successfully.
    In the logs of IIS finded records:
    2014-08-26 09:23:01 172.16.0.31 GET /owa/ &ex=UE:Microsoft.Exchange.Data.Storage.TooManyObjectsOpenedException 443 DOMAIN\username 172.16.4.218 Mozilla/4.0+(compatible;+MSIE+7.0;+Windows+NT+6.1;+WOW64;+Trident/5.0;+SLCC2;+.NET+CLR+2.0.50727;+.NET+CLR+3.5.30729;+.NET+CLR+3.0.30729;+Media+Center+PC+6.0;+InfoPath.3;+.NET4.0C;+.NET4.0E;+.NET+CLR+1.1.4322;+MS-RTC+LM+8)

    Someone faced with such issue?
    Have ideas to solve the issue?

    Hi,
    Event 9646 occurs if a MAPI client opens more than the default value. You can follow the steps below for troubleshooting:
    1. Run regedit, and then click OK.
    2. Expand the following registry subkey:
       HKEY_LOCAL_MACHINE \SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem
    3. Right-click ParametersSystem, point to New, and then click  Key.
    4. Type MaxObjsPerMapiSession, and then press ENTER to name the new subkey.
    5. Right-click MaxObjsPerMapiSession, click New, and then click DWORD Value.
    6. Type Object_type, and then press ENTER to name the object.
    Note: Object_type is the name of the object type in the error message that is mentioned in the "Symptoms" section.
    Hope this can be helpful to you.

  • Error logging problem:

    error logging problem:
    I would like to implement an error logger that will do the following tasks when a error/exception arrises:
    - surpress the DacfErrorPopupLogger
    - alert the user that an error has occured with a simplified popup (create a global listener then use the ErrorAttributes to create the text of the popup)
    - log the error in a file with a timestamp and all error information
    - later if the above works....i would like to add the error attributes (time stamp, error type) to a oracle object/ Jdev domain.
    Questions:
    What is the best technique to use....errorManager, error logger ...?? combination
    How do i use the error manager to register listners for the errors?.
    In the following code i am not sure how to access the ErrorsAttributes[] array that is returned by loggerReader.getErrors();
    Any general tips places to find sample code on errorManager or associated interfaces, will be appreciated
    I used the OutPutStreamLogger to write error information to a FileOutputStream then a loggerReader to get the error attributes from the file. The reason i went in this direction is because i found some smple code on the outputStream logger.

    Between version 1.0 and 2.0 the API in the JBCL controls has
    changed. We are actually moving away from JBCL completely (please
    do send feedback if you have a comment on that) to a Swing and
    Infobus standard based library of visual JavaBeans.
    You will still be able to use the JBCL controls in JDeveloper
    2.0. The best thing to do is to take your 1.x based application
    AND the 1.x based JBCL.ZIP file into your new environment. This
    way you will be able to continue to use these apps and
    components. Taking the 1.x JBCL.ZIP file will make sure you have
    the same version of the JBCL library that you were used to in
    version 1.x.
    Hope this help,
    -Roel.

    Need tyo make sure the problem is with the query/workbook are general issue with all workbooks/query.
    1. Make sure the base query of work book is still executable. RRMX/RSRT.
    2. Execute the work book in Bex/Excel and look for definition of workbook; there might be some thing in the workbook referencing other than base query.
    3. If other workbook are also not working? need to check if other users have same issue.?
    Hope this will help to narrow the problem.
