• Mysql Connection Error from 1.1.1 to 1.2.1

  - by Chromag

  I upgraded from 1.1.1 to 1.2.1 and I seem to be getting the following exception when it attempts to connect to MySQL: The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server. at com.mysql.jdbc.Util.handleNewInstance(Util.java:407) at com.mysql.jdbc.SQLError.createCommunicationsException(SQLError.java:1116) at com.mysql.jdbc.MysqlIO.<init>(MysqlIO.java:343) ... Caused by: java.net.ConnectException: Connection refused at java.net.PlainSocketImpl.socketConnect(Native Method) at java.net.PlainSocketImpl.doConnect(PlainSocketImpl.java:333) at java.net.PlainSocketImpl.connectToAddress(PlainSocketImpl.java:195) I've confirmed that MySQL is indeed running and seems to be working fine. The following is the line from my application.conf file (with user/pass/db replaced): db=mysql:username:password@databasename I also tried using the full JDBC configuration. Did I miss something? This worked just fine in 1.1.1. I'm running MySQL 5.1.41. Thanks.

• Sending large XML from Silverlight to SVC (WCF)

  - by alexbf

  Hi! I want to send a big XML string to a WCF SVC service from Silverlight. It looks like anything under about 50k is sent correctly but if I try to send something over that limit, my request reaches the server (BeginRequest is called) but never reaches my SVC. I get the classic "NotFound" exception. Any idea on how to raise that limit? If I can't raise it? What are my other options? Thanks, Alex

• What do I put in my Ruby (JRuby) code to break into the debugger?

  - by Daryl Spitzer

  I'm familiarizing myself with some JRuby code, and I'd like to be able to place a breakpoint in the code and run (as usual) from the command-line, having it break into the debugger when it gets to that point. Is there something I can put in my code to force JRuby to break into the debugger? I've tried running jruby -r debug foo.rb (instead of the usual jruby foo.rb), and then setting a breakpoint with b bar.py:98, and then continuing. But the debugger stops every time there's an exception, and there seem to be a lot of them before it gets to the line of code I'm interested in. I'd like to be able to put the "break-into-debugger" line(s) in my code and run jruby foo.rb and have the first place the debugger stops be at that line. (i.e. I'm looking for the Ruby/JRuby equivalent of import pdb;pdb.set_trace() in Python.)

• Using iPhone Core Data to many Relationship

  - by BLeB

  When I define a to many relationship between entities in Xcode and then generate the data class from the entity I get a header with the following methods defined: @interface PriceList (CoreDataGeneratedAccessors) - (void)addItemsObject:(PriceListItem *)value; - (void)removeItemsObject:(PriceListItem *)value; - (void)addItems:(NSSet *)value; - (void)removeItems:(NSSet *)value; @end When I attempt to call addItemsObject with the following code a doesNotRecognizeSelector exception is thrown. PriceListItem *item = [NSEntityDescription insertNewObjectForEntityForName:@"PriceListItem" inManagedObjectContext:managedObjectContext]; item.cat = [attributeDict valueForKey:@"c"]; item.sel = [attributeDict valueForKey:@"s"]; [self addItemsObject:item]; From what I have read I do not have to implement these methods and that they are generated at runtime. Any ideas?

• How can I remove a browser's cache server-side, using ASP.NET?

  - by Noman

  How can I remove a browser's cache server-side, using ASP.NET (C#)? A coupon shows by itself (I believe it comes from cache as I did also browse for other apparel sites). It breaks my JavaScript as well as my server-side code, as I am using an UpdatePanel for Ajax, and it duplicates the UpdatePanel's ID. I have renamed the UpdatePanel's ID, but it makes no difference. It generates "Invalid view State" exception. The coupon name is "FastSave" What I have tried: Response.Cache.SetExpires(DateTime.UtcNow.AddMinutes(-1)); Response.Cache.SetCacheability(HttpCacheability.NoCache); Response.Cache.SetNoStore();

• How do you handle exceptions from API/library in your code?

  - by 5YrsLaterDBA

  I have the following lines of code: FileInfo dbFile = new FileInfo(fileName); dbFileSize = (long)dbFile.Length / 1024;//KB There are 8 possible exceptions from new FileInfo(fileName) and dbFile.Length calls. I cannot just ignore them. I have to catch them. What you are going to do with those 8 exceptions? Catch them separately (too many lines)? Catch only ONE by catching the super Exception excepton? or ...

• Capturing Mac OS X System Audio output with Python

  - by richbs

  Hello, I've been trying to "hijack" the Mac OS X system audio using PyAudio and save to a wav in python. That is, I do not want to record from an input device such as a microphone. I want to grab the sound output from any or all applications. I have followed the tutorials on the PyAudio site but these do not appear to cover my use case and when I try to read from the output stream I unsurprisingly get the paCanNotReadFromAnOutputOnlyStream exception. Fair enough! Is there a way to do what I am proposing with the PyAudio or other FOSS Python Library?

• Showing/Hiding the main form in C#

  - by DazSlayer

  I am working on a program where clicking on a button on form1 will open form2. I will then hide form1 until form2 is closed. The problem I have is that I cannot get form1 to show after form2 closes. Any ideas on how to fix this? try { Form1.ActiveForm.Hide(); AddGradeForm = new Form2(Form.NumberOfSelections); AddGradeForm.ShowDialog(); MessageBox.Show(AddGradeForm.Result.ToString()); } catch (Exception i) { Form1.ActiveForm.Hide(); AddGradeForm.Dispose(); AddGradeForm = new Form2(Form.NumberOfSelections); AddGradeForm.ShowDialog(); MessageBox.Show(AddGradeForm.Result.ToString()); } Form1.ActiveForm.Show(); ERROR: NullReferenceException was unhanded.

• Protocols/Interfaces in Ruby

  - by fifigyuri

  While coding in Ruby I did not really miss the type-orientedness of Java or C++ so far, but for some cases I think it is useful to have them. For Python there was a project PyProtocols which defined interfaces and protocols for objects. Does a similar initiative also exist for Ruby? I would like to be able to declare the expected parameters for some methods for some objects (for the entire code I find such think useless). It the method during the execution receives an unexpected input, it tries to adapt it or if it cannot, it throws an exception. Does something similar exist for Ruby? Introducing types for a type-less language like Ruby might sound freak, but I think types are sometimes useful. Thanks for help.

• Equivalent of c# 'as' command in c++?

  - by Sam

  In c# you can use as to convert a type or get null: Object o = Whatever(); String s = o as String; Is there a similar easy way to achieve this in c++? I'm using Visual Studio 2010, if thats important. [update] Remember, there is a very important difference between casting and using as. Casting (at least in c#) will throw an exception if the type does not match: Object o = null; String s = (String)o; // will crash.

• will destroyed() be emitted if the constructor of a class derived from QObject throws?

  - by PorkyBrain

  Ive seen Qt GUI syntax like the following all over the place: myDialog::myDialog(QWidget *parent, Qt::WFlags flags):QDialog(parent, flags) { QPushButton *button = new QPushButton("&Download", this); QVBoxLayout *layout = new QVBoxLayout(this); //something that can throw here layout ->addWidget(button ); setLayout(layout); } I've always wondered if this can leak in the event of an exception because the "this" I'm giving as a parent to button and layout is not fully constructed so it might not destroy its children. I tried it out in MSVC2010 Qt4.8.3 and it looks like as soon as the base QObject class is fully created (which is done first of course) it is ok to pass "this" to other objects in the constructor, they will destroyed correctly. I haven't found the spot in the Qt docs guaranteeing this though, can someone point me to it so I have assurance that this will not change in the future?

• Partition loop understanding

  Why the loop body of the partition method never throws an ArrayIndexOutOfBounds Exception? public static int partition( int[] a, low, high ) { int k = low, m = low; /* loop invariant: * low <= k <= m <= high and * all elements in a[low..k-1] are RED (i.e., < pivot) and * all elements in a[k..m-1] are BLUE (i.e., >= pivot) */ while (m != high) { if (a[m] >= pivot) // a[m] is BLUE { } else { // a[m] is RED swap(a,k,m); k = k+1; } m = m+1; } return k; }

• No mapping for LONGVARCHAR in Hibernate 3.2

  - by jimbokun

  I am running Hibernate 3.2.0 with MySQL 5.1. After updating the group_concat_max_len in MySQL (because of a group_concat query that was exceeding the default value), I got the following exception when executing a SQLQuery with a group_concat clause: "No Dialect mapping for JDBC type: -1" -1 is the java.sql.Types value for LONGVARCHAR. Evidently, increasing the group_concat_max_len value causes calls to group_concat to return a LONGVARCHAR value. This appears to be an instance of this bug: http://opensource.atlassian.com/projects/hibernate/browse/HHH-3892 I guess there is a fix for this issue in Hibernate 3.5, but that is still a development version, so I am hesitant to put it into production, and don't know if it would cause issues for other parts of my code base. I could also just use JDBC queries, but then I have to replace every instance of a SQLQuery with a group_concat clause. Any other suggestions?

• check for null date in CASE statement, where have I gone wrong?

  - by James.Elsey

  Hello, My source table looks like this Id StartDate 1 (null) 2 12/12/2009 3 10/10/2009 I want to create a select statement, that selects the above, but also has an additional column to display a varchar if the date is not null such as : Id StartDate StartDateStatus 1 (null) Awaiting 2 12/12/2009 Approved 3 10/10/2009 Approved I have the following in my select, but it doesn't seem to be working. All of the statuses are set to Approved even though the dates have some nulls select id, StartDate, CASE StartDate WHEN null THEN 'Awaiting' ELSE 'Approved' END AS StartDateStatus FROM myTable The results of my query look like : Id StartDate StartDateStatus 1 (null) Approved 2 12/12/2009 Approved 3 10/10/2009 Approved 4 (null) Approved 5 (null) Approved StartDate is a smalldatetime, is there some exception to how this should be treated?

• How to set an error message from EditorPart when ApplyChanges returns false?

  - by jmservera

  I'm developing a custom ASP.Net WebPart using the WebPartManager and I'm creating a custom EditorPart too. For its EditorPart.ApplyChanges method I set the return value to false whenever there is an error. In the EditorZone I get a standard error message indicating that some error happened to the editor, but I want to change that message. Is that possible? Something like... public override bool ApplyChanges() { try { // save properties return true; } catch(Exception ex) { ErrorMessage = ex.Message; // is there any similar property I can fill? return false; } }

• Using * Width & Precision Specifiers With boost::format

  - by John Dibling

  I am trying to use width and precision specifiers with boost::format, like this: #include <boost\format.hpp> #include <string> int main() { int n = 5; std::string s = (boost::format("%*.*s") % (n*2) % (n*2) % "Hello").str(); return 0; } But this doesn't work because boost::format doesn't support the * specifier. Boost throws an exception when parsing the string. Is there a way to accomplish the same goal, preferably using a drop-in replacement?

• Using Linq to filter parents by their children

  - by Nick L

  Having some problems with my Silverlight app (with RIA services) filtering my results. The idea is on the client I set up the EntityQuery and its filters and call load. However this isn't working for me. Heres my code. public void FireQuery(string filterValue) { EntityQuery<Parent> query = m_ParentDomainContext.GetParentQuery(); query = query.Where(p => p.Children.Any(c => c.Name.Contains(filterValue))); m_ParentDomainContext.Load(query, Query_Completed, null); } Compiles just fine, however, runtime I get "Query operator 'Any' is not supported." Exception. Does anyone know of a good way to filter like this? Again, I'm looking for a way to set this up on the client.
