CharacterUtiltites.isLetterOrDigit (int) support

J2ME, character does not support the isLetterOrDigit(), so RIM has created the net.rim.device.api.util.CharacterUtilities of the class that contains this method. However, RIM has just implemented isLetterOrDigit (char), which means that we cannot check whether a Unicode character is a letter or a number.

A someone has encountered this problem and found a way to work around it? Also, does anyone know if RIM intends to support the Unicode version of this method in the future? It does not appear in the 5.0.0 API documentation.

If your Unicode character is stored as an int variable, you can cast it as a tank and use CharacterUtilities.  This should work for most Unicode characters.

  • HPE 190 t: will HPE 190-t support a 3 TB internal hard drive

    My main hard drive failed on my Pavilion Elite HPE 190 - t. I bought a toshiba 3 to int. HD to replace the original and I see only about 800 GB of total storage space. I have a second 2 TB drive and it shows the amount of entire storage.

    Is it possible for me to get full use of 3 TB drive or am I limited by Truckee and 529 bios motherboard?

    Hello

    You need a complete UEFI BIOS to support a hard drive 3 TB as a hard drive to boot and your PC does not have this level of BIOS.

    However, you can use the HD 3 to as a hard only to data if you format GPT.

    The best situation is to use a hard drive that is less than 2 TB and is not a model of advanced format.

  • DeskJet 3630: HP DeskJet 3630 doesn't recongize 803 black carteidge int

    Hello. I met a problem when I using 803 ink cartridge black (instead of 63 black cartridge int) in my DeskJet 3630. The printer cannot detect the 803 even black ink cartridge, I tried two new 803 black ink cartridges that have been purchased in the supermarket. If DeskJet 3630 can use only 63 ink cartridge? If not, could you please give me some suggestions on how to fix this? Thank you very much.

    BTW: I tried all the solutions on the site of HP comfortable support.

    You bought the printer in a country and are now in another country?  You will need to Contact HP to ask a "regionalization Reset." Do not charge for this, it is covered under the warranty of the cartridge. You will need to have access to your computer and printer then on line with HP. You will also need to have a set of cartridges for the new region, once completed reset cartridges of region of origin no longer works.  Webpage of HP on the subject is here.

  • Binary variable display does not work for long long int

    According to this document , CVI 2013 supports long int. While clang is without doubt, the variable point of view don't always support it... If you want to look at the value of a long int variable and choose binary format, the value can be too large to be displayed, see below: nothing is displayed if too many digits are necessary - in fact 64 digits must be supported but are not

    Yes, looks like a bug: 423654.

    Long long support are not new for 2013 or said by the way. They have been supported since 2009, also a long time that you have enabled the C99 extensions.

  • Function editor does not support the pointer to the digital type

    Am I missing something or is it true that the CVI function Panel Editor does not support specifying a type parameter as a pointer of type number?

    I see no reason why he wouldn't or shouldn't.  It supports the pointer to char.  And it supports a table name (which, in C, is a pointer to the first element of the array).

    I guess I could use the array form as a pointer, but surely it's confusing when dealing with a simple pointer to a numeric scalar type.

    I am using the function Panel Editor only for the purpose of creating a dictionary of type so I can call functions DLL in VB.  Y at - he know somewhere how CVI types could are mapped to the VB types when you use the type dictionary?   for example, what happens if I use an unsigned int in a function parameter (VB does not support unsigned integers)?

    Menchar

    Hi Menchar,

    To create a pointer to an integer as a parameter to a function panel, you have two different options.

    First of all, all output parameters are defined as the default pointers.  So if you create an output parameter of type "int", he creates a ' int *' parameter.

    Second, if you want it to appear in the entry list, you can create a data type in CVI which will appear at the bottom of the list.  Data types to change your data types, go to the Options"(you must have a function Editor tab open and selected Panel to make this option available).  Enter the name of the type (in this case ' int * ') and click the Add button.  The new "int *" option should now appear at the bottom of the list.

    Third, you can use the array form (int []), but as you say, which can be confusing for other people looking at the code.  Or the other of the two first options are better choices.

    As for your second question, here's a link to a page MSDN showing types in Visual Basic and their representations .NET: http://msdn.microsoft.com/en-us/library/47zceaw7 (VS.80) .aspx.  This allows to make a comparison between VB and ANSI C data types.  For example, to ask on unsigned integers, and this site shows that Visual Basic has an Integer type (-2,147,483,648 through 2,147,483,64) and an unsigned return, UInteger (between 0 and 4 294 967 295).  From what I can tell, VB has signed versions of all its digital representations.  You can then take this with a list of ANSI C data types to convert between the two.  A list of ANSI C data types can be found here: http://www.exforsys.com/tutorials/c-language/c-programming-language-data-types.html

  • Physical channel selected does not support the type of output required by virtual channel

    I use a box USB-6251.  Inside of MAX, I can set the device to Dev1 / ao1 sine wave generation and if he have output a sine wave.  When I use DAQmx DAQmxCreateAOFuncGenChan function I get error: selected physical channel does not support the type of output required by virtual channel.  The pilot DAQmx does FuncGen on the box USB-6251 or MAX out a set of tensions?

    Hi Paul,.

    Welcome to the Forums EITHER!  The DAQmxCreateAOFuncGenChan is supported only on products Elvis II.  For other devices, including the 6251, you must use the ordinary DAQmxCreateAOVoltageChan and create your own data buffer.  I would recommend looking in the following example:

    Start > all programs > National Instruments > NOR-DAQ > textual Code > ANSI C examples...

    Analog on > generate voltage > Cont Gen Volt Wfm - Int Clk

    In MAX the Sinewave output is used as a test signal - in this case MAX is a period of the wave sine values to write to the buffer and generate these data.  Again, you can produce a sine wave (or any other function) using the AOVoltageChan, but the AOFunctionGenChan is used only with Elvis II.  Just generate data points for the sine wave that will produce DAQ hardware.

  • 3 TB Seagate int startup problem. by car

    BIOS Dell XPS8300 A03 8 GB win 7 home Prem recently installed Samsung 840evo using their cloned migration software my system on the ssd. Works great, best upgrade I've ever done. Tried to add a 3to int sata seagate to port 1 to maintain 6gbs of data only. Tried using disk of window then seagates Assistant tools disk management for formatting in the TC as a simple volume. When formatting two ways BSOD received after restarting the player present themselves as a 2790 GB drive but right-clicking in responsible Disk Error Message received: "the operation failed because the disk management console view is not up to date. Refresh the view by using the refresh task. " If the problem persists, close the disk management console, and then restart disk management or restart the computer"

    Could get in shape with a sata docking station usb with my asus laptop win 7. completed end and readable, then tried to install it with well-known sata and XPS power cable. Would not boot disk, disconnected, and it started late.

    The full Dell diagnostics ran with nothing else succeeded not only blue detect screen but after 30 minutes the client diagnosis of Dell is still underway and seems stuck.

    All suggestions experience anything similar and possible. Spent a lot of time on the phone with seagate support but once the laptop was able to successfully form the 3 TB essentially put the blame on the XPS

    Thanks for any help

    Hi Doug,.

    No problem, those who may be useful details.

    I would try upgrading the BIOS. It can't hurt. I would also try this version of the Intel RST. It is more recent than what Dell provides.

    As with all updates, do them one at a time, and then check the results. The best way to install a BIOS update is with a USB bootable, rather than inside Windows.

  • Problems to regain the QML C++ enum; JS is undefined instead of an int.

    I followed the path of BB to regain the enums in C++ QML discussed here:

    http://supportforums.BlackBerry.com/T5/native-development/HOWTO-C-enum-in-QML/m-p/2345641#M21139

    However I'm getting back the value JS "undefined" of my logic of C++ biz instead of what I want (i.e., an integer that corresponds to my enum type).

    The scenario is that I want to restore the data from the application of a backup and do a lot of validation of each step of the restore if something goes wrong, I can post a dialogue of restoration has failed no credits that could help the user recover.

    I have a class enum setting as follows:

    #ifndef RESTOREFAILURETYPE_HPP_
    #define RESTOREFAILURETYPE_HPP_
    
    #include 
    
    class RestoreFailureType: public QObject
    {
    
        Q_OBJECT
        Q_ENUMS(Type)
    
    public:
    
        enum Type {
            Success = 0,
            JSONReadFail = 1,
            UndoFileRemoveFail = 2,
            CopyToUndoFail = 3,
            DestFileRemoveFail = 4,
            CopyBackupFileFail = 5,
            ValidateSchemaFail = 6
        };
    
        RestoreFailureType();  // Empty constructor defined in .cpp file
        virtual ~RestoreFailureType(); // Empty destructor defined in .cpp file
    };
    
    #endif /* RESTOREFAILURETYPE_HPP_ */
    

    I save this class as an increables type in my app delegate:

    qmlRegisterUncreatableType("myApp.restoreFailureType", 1, 0, "RestoreFailureType", "RestoreFailureType provides enum values.  It cannot be instantiated.");
    

    I have a DataManager class that takes care of managing the operations of store, backup, restore, etc CRUD/user support, with what restoration function:

    In DataManager.hpp:

    Q_INVOKABLE RestoreFailureType::Type restoreFromBackup(QString backupFileName, int selectedIdForUndo);
    

    in DataManager.cpp (here I show a fake draft.  Since not even that much is still working, the rest of the logic of biz is not relevant to this discussion:

    RestoreFailureType::Type DataManager::restoreFromBackup(QString backupFileName, int selectedIdForUndo) {
        return RestoreFailureType::Success;
    }
    

    And in my QML UI layer, I import the type:

    import myApp.restoreFailureType 1.0
    

    And a FilePicker component supports passing the name of the backup file to the DataManager.  The FilePicker and his onFileSelected() slot:

          FilePicker {
                id: backupRestoreFilePicker
                type: FileType.Other
                allowOverwrite: true
                directories : ["/accounts/1000/shared/documents/MyApp"]
                viewMode: FilePickerViewMode.ListView
                onFileSelected: {
                    if (mode == FilePickerMode.Saver) {
                        // Save mode stuff for doing backups
                    } else if (mode == FilePickerMode.Picker) {
                        var restoreResult =  _dataManager.restoreFromBackup(selectedFiles, _appSettings.selectedId);
                    }
                }
            }
    

    I tried to remove the code down for everything that is relevant to this question.

    When I put a breakpoint on the line where the var restoreResult JS is defined:

    var restoreResult =  _dataManager.restoreFromBackup(selectedFiles, _appSettings.selectedId);
    

    and step, restoreResult, var JS becomes the value "indefinite".  From what I read in the thread mentioned above, restoreResult is supposed to get a whole number (in this case he should get zero method justiciable restoreFromBackup how I generated), that I can then compare to imported enum type.  I should be able to compare the return value of restoreFromBackup to see if it is equal to one of:

    RestoreFailureType.Success
    
    // or:
    
    RestoreFailureType.JSONReadFail
    
    // or:
    
    RestoreFailureType.UndoFileRemoveFail
    
    // or:
    
    RestoreFailureType.CopyToUndoFail
    
    // etc...
    

    I think others have got it working, and miss me him probably just a few details.  A lot of satisfaction to anyone who can identify the error/omission or even give a good lead.  In addition, comments are welcome on if I'm trying to manage this scenario in a recommended manner.  My intention is to use the listed failure code to customize a SystemDialog message that may help the user recover from a restore operation has failed.  The restore file might have been corrupted in a way that is not analyzable JSON, or the user could have selected a file that isn't even a backup file created by my application, or they could have revoked authorization, or JSON can be analyzable, but the user could not resist the temptation to manually change the values in their backup file etc.

    Hmm,

    Sometimes all you have to do is to talk, even if you speak to yourself.

    I changed my function DataManager to return my type listed as int instead of as the enum, and I don't have the correct integers in QML, anything can still be compared using the enumerated type.  So:

    Q_INVOKABLE RestoreFailureType::Type restoreFromBackup(QString backupFileName, int selectedIdForUndo);
    

    becomes

    Q_INVOKABLE int restoreFromBackup(QString backupFileName, int selectedIdForUndo);
    

    and

    RestoreFailureType::Type DataManager::restoreFromBackup(QString backupFileName, int selectedIdForUndo) {
        return RestoreFailureType::Success;
    }
    

    becomes

    int DataManager::restoreFromBackup(QString backupFileName, int selectedIdForUndo) {
        return RestoreFailureType::Success;
    }
    

    and I can do now:

    var restoreResult =  _dataManager.restoreFromBackup(selectedFiles, _appSettings.selectedId);if(restoreResult == RestoreFailureType.Success) { // Do success stuff} elseif(restoreResult == RestoreFailureType.JSONReadFail { // Do JSON read fail stuff} else...
    

    This isn't quite how it was recommended in the thread, I mentioned in the previous post... but it seems to work for what I need.
