  • BlackBerry - Exception with null message when sending sms using Connector

    - by vikram deshpande
    I used code given but I am getting "IOCancelledException" and "IOException". And IOCancelledException.getMessage() / IOException.getMessage() giving null string, it does not give error message. Please help me understaing reason. class SMSThread extends Thread { Thread myThread; MessageConnection msgConn; String message; String mobilenumber; public SMSThread(String textMsg, String mobileNumber) { message = textMsg; mobilenumber = mobileNumber; } public void run() { try { msgConn = (MessageConnection) Connector.open("sms://+" + mobilenumber); TextMessage text = (TextMessage) msgConn .newMessage(MessageConnection.TEXT_MESSAGE); text.setPayloadText(message); msgConn.send(text); msgConn.close(); } catch (IOCancelledException ioce) { System.out .println("IOCancelledException: " + ioce.getMessage()); } catch (IOException ioe) { System.out.println("IOException: " + ioe.getMessage()); } catch (Exception e) { System.out.println("Exception: " + e); } } }

  • Reference non-GAC version of DLL in Visual Studio 2010

    - by Eric J.
    This is similar to Add Non-GAC reference to project but the solutions presented there don't seem to help. I have a WinForms UI Library (Krypton from ComponentFactory) installed in the GAC. There's a bug I want to track down in that library, so I added the source code to my solution, removed the old references from my WinForms project to Krypton DLLs, added them back as a project references, ensured Copy Local is set to true, double-checked that the path (on reference properties tab) points to my local project, and... ...the GAC version is still being used while debugging. I cannot set a breakpoint in the Krypton source, Debugger.Break() or other code changes to not execute, and when I start the Visual Studio 2010 debugger, I see a Loading from ... GAC_MISL message relating to the Krypton DLLs flash by in the VS 2010 status bar. The DLLs are not copied to the WinForm's Debug folder. How can I reference the "project" version of the files while debugging while leaving them registered in the GAC?

  • Checked equivalent to IllegalArgumentException?

    - by jv1975oid
    I have a method that takes an enum as a parameter and returns some information dependent on that parameter. However, that enum contains some values which should not be handled, and should raise an error condition. Currently the method throws an IllegalArgumentException but I would like this to be a checked exception to force callers to catch it (and return gracefully, logging an error). Is there something suitable or should I create my own Exception subclass? I'm open to other patterns as well. A reasonable reaction would be that all values of the enum should be handled, but that isn't the case. When a new value is added to the enum, I want to make sure that this method does the right thing - alerting a human is preferable to using some default return value in this case. Thanks for any advice.

  • Erlang ODBC parameter query with null parameters

    - by Schlomer
    Is it possible to pass null values to parameter queries? For example Sql = "insert into TableX values (?,?)". Params = [{sql_integer, [Val1]}, {sql_float, [Val2]}]. % Val2 may be a float, or it may be the atom, undefined odbc:param_query(OdbcRef, Sql, Params). Now, of course odbc:param_query/3 is going to complain if Val2 is undefined when trying to match to a sql_float, but my question is... Is it possible to use a parameterized query, such as: Sql = "insert into TableY values (?,?,?,?,?,?,?,?,?)". with any null parameters? I have a use case where I am dumping a large number of real-time data into a database by either inserting or updating. Some of the tables I am updating have a dozen or so nullable fields, and I do not have a guarantee that all of the data will be there. Concatenating a SQL together for each query, checking for null values seems complex, and the wrong way to do it. Having a parameterized query for each permutation is simply not an option. Any thoughts or ideas would be fantastic! Thank you!

  • Linenumber for Exception thrown in runtime-compiled DotNET code

    - by David Rutten
    Not quite the same as this thread, but pretty close. My program allows people to enter some VB or C# code which gets compiled, loaded and executed at runtime. My CompilerParams are: CompilerParameters params = new CompilerParameters(); params.GenerateExecutable = false; params.GenerateInMemory = true; params.IncludeDebugInformation = false; params.TreatWarningsAsErrors = false; params.WarningLevel = 4; When this code throws an exception I'd like to be able to display a message box that helps users debug their code. The exception message is easy, but the line-number is where I got stuck. I suspect that in order to get at the line number, I may need to drastically change the CompilerParameters and perhaps even the way these dlls get stored/loaded. Does anyone know the least steps needed to get this to work?

  • How to catch specific exception without error number?

    - by CJ7
    I need to catch the following specific exception: System.Data.OleDb.OleDbException was caught ErrorCode=-2147467259 Message="The changes you requested to the table were not successful because they would create duplicate values in the index, primary key, or relationship. Change the data in the field or fields that contain duplicate data, remove the index, or redefine the index to permit duplicate entries and try again." Source="Microsoft JET Database Engine" I'm not sure what ErrorCode is but it looks unreliable. Can I rely on Message being identical across platforms? Is the only solution to do a text search of Message for words like duplicate and primary key? Note: see my question here for why I need to catch this exception.

  • asp.net Background Threads Exception Handling

    - by Chris
    In my 3.5 .net web application I have a background thread that does a lot of work (the application is similar to mint.com in that it does a lot of account aggregation on background threads). I do extensive exception handling within the thread performing the aggregation but there's always the chance an unhandled exception will be thrown and my entire application will die. I've read some articles about this topic but they all seem fairly outdated and none of them implement a standard approach. Is there a standard approach to this nowadays? Is there any nicer way to handle this in ASP.NET 4.0?

  • JDBC ResultSet.getString Before/After Start/End of ResultSet Exception

    - by Geowil
    I have done a lot of searching about this topic through Google but I have yet to find someone using getString() in the way that I am using it so I have not been able to fix this issue in the normal ways that are suggested. What I am trying to do is to obtain all of the information from the database and then use it to populate a table model within the program. I do so by obtaining the data with getString and place it into a String[] object: try { while (rSet.next()) { String row[] = {rSet.getString("DonorName"),rSet.getString("DonorCharity"),((String)rSet.getString("DonationAmount"))}; model.addRow(row); } } However I am always getting a dialog error message stating those error messages in the title: Exception: Before start of result set Exception: After end of result set The data is still added and everything works correctly but it is just annoying to have to dismiss those message windows. Does anyone have some suggestions?

  • Sending an email when an Exception is Thrown

    - by hariubc
    Hi: I have written a java class where if a method throws an exception, an email is sent, via java mail, with a report to the administrators. It works - my question is w.r.t elegance - to catch the exception thrown by the main method, the sendEmail() method resides in the catch block of the main method. The sendEmail() method has its own try-catch block. In effect - it looks like below - is there a more beautiful way of writing this? try { foo; } catch { try{ sendEmail(); } catch { log(e.message); } }

  • The Java interface doesn't declare any exception. How to manage checked exception of the implementat

    - by Frór
    Let's say I have the following Java interface that I may not modify: public interface MyInterface { public void doSomething(); } And now the class implementing it is like this: class MyImplementation implements MyInterface { public void doSomething() { try { // read file } catch (IOException e) { // what to do? } } } I can't recover from not reading the file. A subclass of RuntimeException can clearly help me, but I'm not sure if it's the right thing to do: the problem is that that exception would then not be documented in the class and a user of the class would possibly get that exception an know nothing about solving this. What can I do?

  • Python continue from the point where exception was thrown

    - by James Lin
    Hi is there a way to continue from the point where exception was thrown? eg I have the following psudo code unique code 1 unique code 2 unique code 3 if I want to ignore the exceptions of any of the unique code statements I will have to do it like this: try: #unique code 1 except: pass try: #unique code 2 except: pass try: #unique code 3 except: pass but this isn't elegant to me, and for the life of me I can't remember how I resolved this kind of problem last time... what I want to have is something like try: unique code 1 unique code 2 unique code 3 except: continue from last exception raised

  • JsonStore.insert() causes exception in extjs

    - by kalan
    I have an EditorGridPanel with toolbar button to add new records. Everything works fine except one scenario. When I try to insert a record which already exists in database, server sends back: {"success":false,"message":"already exists","data":{}} but grid creates a new row marked with red triangle. If after that I try to insert a new record (even if it doesn't exist in database), everything works fine on the server side, but i get an 'uncaught exception' in firebug. It says: 'uncaught exception: Ext.data.DataReader: #realize was called with invalid remote-data. Please see the docs for DataReader#realize and review your DataReader configuration.' why is that?

  • C++ catch constructor exception

    - by aaa
    hi. I do not seem to understand how to catch constructor exception. Here is relevant code: struct Thread { rysq::cuda::Fock fock_; template<class iterator> Thread(const rysq::cuda::Centers &centers, const iterator (&blocks)[4]) : fock_() { if (!fock_) throw; } }; Thread *ct; try { ct = new Thread(centers_, blocks); } catch(...) { return false; } // catch never happens, So catch statement do not execute and I get unhandled exception. What did I do wrong? this is straight C++ using g++.

  • c++: strange syntax in what() method of std::exception

    - by Patrick Oscity
    When i am inheriting from std::exception in order to define my own exception type, i need to override the what() method, which has the following signature: virtual const char* what() const throw(); This definitely looks strange to me, like if there were two method names in the signature. Is this some very specific syntax, like with pure virtual methods, e.g.: virtual int method() const = 0; or is this a feature, that could somehow be used in another context, too? And if so, for what could it be used?

  • pass by reference but reference to data and not to variable

    - by dorelal
    This is psesudo code. In what programming language this is possible ? def lab(input) input = ['90'] end x = ['80'] lab(x) puts x #=> value of x has changed from ['80'] to ['90] I have written this in ruby but in ruby I get the final x value of 80 because ruby is pass-by-reference. However what is passed is the reference to the data held by x and not pointer to x itself same is true in JavaScript. So I am wondering if there is any programming language where the following is true.

  • C++ constant reference lifetime

    - by aaa
    hello I have code that looks like this: class T {}; class container { const T &first, T &second; container(const T&first, const T & second); }; class adapter : T {}; container(adapter(), adapter()); I thought lifetime of constant reference would be lifetime of container. However, it appears otherwise, adapter object is destroyed after container is created, leading dangling reference. What is the correct lifetime? how to correctly implement binding temporary object to class member reference? Thanks

  • latex table reference

    - by Tim
    Hi, I wrote a long table with a label in a tex file and \input it into my main tex file. The reference in the main tex file to the table, however, does not show the numbering of the table but the one of the next table that are written directly in the main tex file. All long tables that are written directly in the main tex file have correct references. How to fix my problem? Must the label be defined in the same tex file as its reference? Thanks and regards! The label is \label{tab:yy}, and the reference is \ref{tab:yy}, and every table has a distinct label.

  • Exception message (Python 2.6)

    - by TurboJupi
    If I want to open binary file (in Python 2.6), that doesn't exists, program exits with an error and prints this: Traceback (most recent call last): File "C:\Python_tests\Exception_Handling\src\exception_handling.py", line 4, in <module> pkl_file = open('monitor.dat', 'rb') IOError: [Errno 2] No such file or directory: 'monitor.dat' I can handle this with 'try-except', like: try: pkl_file = open('monitor.dat', 'rb') monitoring_pickle = pickle.load(pkl_file) pkl_file.close() except Exception: print 'No such file or directory' Does anybody know, how could I, in caught Exception, print the following line? File "C:\Python_tests\Exception_Handling\src\exception_handling.py", line 11, in <module> pkl_file = open('monitor.dat', 'rb') So, program would not exits, and I would have useful information.

  • Reference Paramters in C++: VERY basic example please.

    - by Sagistic
    I am trying to understand how to use reference parameters. There are several examples in my text, however they are too complicated for me to understand why and how to use them. Could anyone give me the MOST basic example of how/why to use one, and perhaps the difference with or without it (what would happen if you didn't attach the '&'). for example, if I've created a function: int doSomething(int& a, int& b), what would be the consequences of not putting in that '&.' I understand that reference variables are used in order to change a formal-reference, which then allows a two-way exchange of parameters. However, that is the extent of my knowledge, and a more concrete example would be of much help. Thank you.

  • returning null or throwing an exception?

    - by MoKi
    I have the following types: typedef QPair < QTime , QTime > CalculatedTimeSlotRange; typedef QList < CalculatedTimeSlotRange > CalculatedTimeSlotRangeList; typedef QHash < quint8 , CalculatedTimeSlotRangeList > TimeSlotsTable; I have a function like the following: const CalculatedTimeSlotRangeList* TimeSlots::getCalculatedTimeSlotRangeList(const quint8 id) const { QHashIterator<quint8,CalculatedTimeSlotRangeList> it(mTimeSlotsTable); while (it.hasNext()) { it.next(); if(it.key() == id) { return &it.value(); } } return NULL; } as you can see my function returns a null if it fails to find a key that matches id. Is this correct? or should I just throw an exception if the key does not exist? how should i throw an exception for this situation?

  • wave.getState() returns null

    - by RMorrisey
    When trying to call wave.getState() in my Google Wave gadget, I get back null (no state object). How can I initialize the Wave state object? I am working in the Wave Sandbox. My ModulePrefs contains the following: <Require feature="wave" /> <Require feature="rpc"/> I got the "rpc" feature from some google groups post when searching for a fix, but it doesn't seem to be any help. The gadget contains a jQuery plugin, which defines the classes I use (not shown), attaches an event handler to the link that shows up in edit mode, and sets up the callback methods with the google wave gadget initializer: $.fn.extend({ $.gork.InitPass.newButtonClick = function newButtonClick() { var jer = new $.gork.InitPass.Player('Jeremias', 12, 2); var delta = {}; delta[jer.name] = jer.serialize(); wave.getState().submitDelta(delta); }; $.gork.InitPass.modeCallback = function modeCallback() { var state = wave.getState(); var mode = wave.getMode(); $.gork.InitPass.getContainer().ipCombatState(state, (mode == wave.Mode.EDIT)); }; $.gork.InitPass.stateCallback = function stateCallback() { $.gork.InitPass.getContainer().ipCombatState( wave.getState(), (wave.getMode() == wave.Mode.EDIT)); alert('state'); }; $.gork.InitPass.init = function init() { if (wave && wave.isInWaveContainer()) { var mode = wave.getMode(); $('.gork-ip-container').ipCombatState(null, (mode == wave.Mode.EDIT)); wave.setModeCallback($.gork.InitPass.modeCallback); wave.setStateCallback($.gork.InitPass.stateCallback); } }; })(jQuery); gadgets.util.registerOnLoadHandler($.gork.InitPass.init); $(function ready() { $.gork.InitPass.getContainer().find('.gork-ip-edit .addSection a.newButton').click( $.gork.InitPass.newButtonClick); }); So there are two main pieces of functionality here: When the mode changes, ipCombatState(...) is called. This changes the visual appearance of the gadget when the user puts the gadget in Edit mode (CTRL+E), by hiding the view DIV and displaying the edit DIV. The newButtonClick callback (which is attached to the link "a.newButton" in the edit container) is supposed to add Jeremias (Nate's Shadowrun character) to the gadget state, so that he'll be appear as a table row in edit mode. I have verified that the initializer method is called, and the view/edit mode switch works just fine (except the state is null). When I click on the new button link (the link at the bottom in edit mode), and trigger the newButtonClick handler, I get an error because wave.getState() also returns null. How can I initialize the wave state so that I can work with it? The purpose of my gadget will be to keep track of combat initiative order in a Shadowrun tabletop game (4th Ed). You can test it out in Wave and see what I have so far: http://gorkwobble.herobo.com/wave/init-pass.xml The actual javascript code is externalized to: http://gorkwobble.herobo.com/wave/init-pass.js P.S. If any Shadowrun players read this, and want to hear about it when I get the gadget working, leave a comment and I'll wave you.
