• Wrong intrepretation of some columns in ireport

  - by Purushotham

  Hi, I got a strange problem. I am using iReport 3.7.1 tool to create some reports. The Query Editor has one query. It shows all the data types of the fields in that query exactly same as the data types shown when I execute it using SQLYOG editor. The problem is here: One field data type is mismatched. I don't know the reason. SQLYOG says it is INTEGER whereas iReport Query Editor says its a long value. BTW The value that assigned to that filed is zero. Can anyone help ? I want to zero-in on this issue.

• Build Event Macros for Other Projects in the Solution

  - by Adam Driscoll

  Is it possible to reference other projects' properties via a macro within a build event? For example: "Tool1" outputs to directory ..\..\bin\Release "Component1" uses "Tool1" in its post-buildevent To get to "Tool1", "Component1"'s project must do something like $(SolutionDir)bin\Release This requires that Tool1 always output to ..\..\bin\Release. If this is changed this breaks the other project. I know there is no indication to this within the macro list but is there a way to reference another project? Maybe like $(OtherProject.TargetDir)... I know WIX has a similar syntax [$(var.OtherProject.TargetDir)] but I think that may be a different mechanism.

• Get class of caller's method (via inspect) in Python

  - by Slava Vishnyakov

  Is it possible to get reference to class B in this example? class A(object): pass class B(A): def test(self): test2() class C(B): pass import inspect def test2(): frame = inspect.currentframe().f_back cls = frame.[?something here?] # cls here should == B (class) c = C() c.test() Basically, C is child of B, B is child of A. Then we create c of type C. Then the call to c.test() actually calls B.test() (via inheritance), which calls to test2(). test2() can get the parent frame frame; code reference to method via frame.f_code; self via frame.f_locals['self']; but type(frame.f_locals['self']) is C (of course), but not B, where method is defined. Any way to get B?

• Silverlight calling windows workflow foundation as a web service

  - by wissem

  hi, I'm trying to call a windows workflow foundation published as a web service from a Silverlight project. When I call it from a console application it works fine because I can add a web reference then I just make an instance of that webservice then I invoke the method I want. The problem is in the silverlight project cause i can just add a service reference so I find myself working with soap stuff that doesn't work at all, and here is the code: private void btnUpdate_Click(object sender, RoutedEventArgs e) { xxxxxxx.Workflow1_WebServiceSoapClient zer = new xxxxx.Workflow1_WebServiceSoapClient(); zer.demanderSubmitReportCompleted += new EventHandler<xxxxxxxxxxxxxxx.demanderSubmitReportCompletedEventArgs>(service2); zer.demanderSubmitReportAsync("zzz", 20000); } public void service2(object sender, xxxxx.demanderSubmitReportCompletedEventArgs e) { string a = e.Result; } plz help ,thanks

• FindControl table cell

  - by rlb.usa

  I want to reference a table cell via it's string ID in my code like this FindControl("tdAnswer_a") because I am manipulating string ID names. The ASPX code looks like this : <table>...<td ID="tdAnswer_a" runat="server" visible="true"> But FindControl is not able to find the table cell. When I reference it by ID like this : tdAnswer_a.Visible = true; in my codebehind, it has no problems. (This is not part of a repeater or gridview). How can I FindControl my table cells via string ID names?

• Haskell: Defaulting constraints to type

  - by yairchu

  Consider this example: applyKTimes :: Integral i => i -> (a -> a) -> a -> a applyKTimes 0 _ x = x applyKTimes k f x = applyKTimes (k-1) f (f x) applyThrice :: (a -> a) -> a -> a applyThrice = applyKTimes 3 The 3 in applyThrice is defaulted by GHC to an Integer as shown when compiling with -Wall: Warning: Defaulting the following constraint(s) to type 'Integer' 'Integral t' arising from a use of 'applyKTimes' So I guess that Integer is the default Integral a => a. Is there a way to define "default types" for other constraints too? Is using default types bad practice? (it does complain when using -Wall..)

• How can I validate input to the edit control of a cell in a DataGridView?

  - by Stuart Helwig

  It appears that the only way to capture the keypress events within a cell of a DataGridView control, in order to validate user input as they type, is to us the DataGridView controls OnEditControlShowing event, hook up a method to the edit control's (e.Control) keypress event and do some validation. My problem is that I've built a heap of custom DataGridView column classes, with their own custom cell types. These cells have their own custom edit controls (things like DateTimePickers, and Numeric or Currency textboxes.) I want to do some numeric validation for those cells that have Numeric of Currency Textboxes as their edit controls but not all the other cell types. How can I determine, within the DataGridView's "OnEditControlShowing" override, whether or not a particular edit control needs some numeric validation?

• How to improve performance of opening Microsoft Word when automated from c#?

  - by Abdullah BaMusa

  I have Microsoft Word template that I automated filling it’s fields from my application, and when the user request print I open this template. but creating word application every time user request print after filling fields is very expensive and lead to some delay while opening the template, so I choose to cache the reference to Word then just open the new filled template. that solve the performance issue as opening file is less expensive than recreating Word each time, but this work while the user just close the document not the entire Word application which when happened my reference to Word become invalid and return with exception says: “The RPC server is unavailable” next time request opening template . I tried to subscribe to BeforClosing event but his trigger for Quitting Word as well as Closing documents. My question is how to know if the word is closing document or quit the entire application so I take the proper action, or any hint for another direction of thinking about improve performance of opening word template.

• How prevent anyone from stealing my shared_ptr?

  - by Kyle

  So, I use boost::shared_ptr for all the various reference-counting benefits it provides -- reference counting for starters, obviously, but also the ability to copy, assign, and therefore store in STL Containers. The problem is, if I pass it to just one "malicious" function or object, the object can save the ptr and then I'll never be able to de-allocate it without the foreign function or object nicely relinquishing its ownership. Ultimately, I try to keep object ownership explicit. I accomplish this by having the owner keep the only shared_ptr to the object, and "guest" objects only store weak_ptrs to the object. I really don't want the "shared" part of shared_ptr, but I'm required to use shared_ptr in order to make weak_ptrs. I want to use scoped_ptr, but it's extremely limited since you can't copy it. You can't store it in a container, you can't lend out weak_ptrs from it, and you can't transfer ownership to a new manager. What's the solution?

• PreparedStatement and 'null' value in WHERE clause

  - by bond

  I am using PrepareStatement and BatchUpdate for executimg a UPDATE query. In for loop I create a Batch. At end of loop I execute batch. Above logic works fine if SQL query used in PrepareStatement does not have null values in WHERE claues. Update Statement fails if there is null value in WHERE clasue. My code looks something like this, connection = getConnection(); PreparedStatement ps = connection.prepareStatement("UPDATE TEST_TABLE SET Col1 = true WHERE Col2 = ? AND Col3 = ?") for (Data aa : InComingData) { if(null == aa.getCol2()) { ps.setNull(1, java.sql.Types.INTEGER); } else { ps.setInteger(1,aa.getCol2()) } if(null == aa.getCol3()) { ps.setNull(2, java.sql.Types.INTEGER); } else { ps.setInteger(2,aa.getCol3()) } ps.addBatch(); } ps.executeBatch(); connection.commit(); Any help would be appreciated.

• How to list all items in custom taxonomy with a permanlink in Wordpress

  - by Constant M

  Hi, Not sure how to word this. I've set up a type in Wordpress called Products. I also have two taxonomies linked to Products called Brands and Categories. When you create a product you can set to which Brand and Category the product belong to. It works perfectly when using the type as permalink to list everything within a type http://sitename.com/products but I can't seem to get the taxonomies working in the same way, ie. list all the items within a taxonomy (like an archive, I suppose): http://sitename.com/brands http://sitename.com/categories Is this possible, and if so, what could I possibly be doing wrong? I would try and set up some rewrite rules in functions.php, but I don't know what the query string looks like if you want to list items in a taxonomy, and if this is even possible. If it helps, I'm using the plugins More Types and Ultimate Taxonomy Manager to create the types and taxonomies.

• JQUERY common function library create script errors. How to avoid?

  - by Cesar Lopez

  Hi all, I am building a common function library but the functions inside need to reference different jquery files, which they may need to be referenced in some pages but not in others. When I called this common function library in one web page which is only going to use one function, and I don't reference the files need it for the other function, then it will create a script error. My question is if it would be possible to stop this script errors like... //This if statement is what I was thinking to stop going through if ($(".objectdate") != null){ //This is the function that is calling other jquery files and creates error. $(document).ready(function() { $(".objectdate").datepicker({ //Code inside. }); }); } Thanks.

• Java: How can I create good looking class docs with Javadoc?

  - by Cheeso

  I'd like to create HTNML documentation for a Java class library that includes programming guide information - beyond just a class reference code examples in the reference doc collapsible regions I want it to look well-styled. Something like this: I think that Javadoc exposes a doclet API that allows other parties to provide doc generation integrated in Javadoc. Is there a doclet option that I can use (for free) that does something a little nicer than the standard javadoc output? I tried googling for this but no luck. Suggestions?

• C99 strict aliasing rules in C++ (GCC)

  - by Checkers

  As far as I understand, GCC supports all of its C99 features in C++. But how is C99 strict aliasing handled in C++ code? I know that casting with C casts between unrelated types is not strict-aliasing-safe and may generate incorrect code, but what about C++? Since strict aliasing is not part of C++ standard (is that correct?), GCC must be specifying the semantics itself. I figure const_cast and static_cast cast between related types, hence they are safe, while reinterpret_cast can break strict aliasing rules. Is this a correct understanding?

• Reasons for sticking with TEXT, NTEXT and IMAGE instead of (N)VARCHAR(max) and VARBINARY(max)

  - by John Assymptoth

  TEXT, NTEXT and IMAGE have been deprecated a long time ago and will, eventually, be removed from SQL Server. However, they are not going to be discontinued right away, not even in the next version of SQL Server, so it's not convenient for my enterprise to transform thousands of columns right away, even if it is using SQL Server 2012. What arguments can I use to postpone this migration? I know there are some advantages in using the new types. But I'm strictly looking for reasons not to migrate my data that is already functioning pretty well in the old types.

• Database system that is not relational.

  - by paan

  What are the other types of database systems out there. I've recently came across couchDB that handles data in a non relational way. It got me thinking about what other models are other people is using. So, I want to know what other types of data model is out there. (I'm not looking for any specifics, just want to look at how other people are handling data storage, my interest are purely academic) The ones I already know are: RDBMS (mysql,postgres etc..) Document based approach (couchDB, lotus notes) Key/value pair (BerkeleyDB)

• What happens to an instance of ServerSocket blocked inside accept(), when I drop all references to i

  - by Hanno Fietz

  In a multithreaded Java application, I just tracked down a strange-looking bug, realizing that what seemed to be happening was this: one of my objects was storing a reference to an instance of ServerSocket on startup, one thread would, in its main loop in run(), call accept() on the socket while the socket was still waiting for a connection, another thread would try to restart the component under some conditions, the restart process missed the cleanup sequence before it reached the initialization sequence as a result, the reference to the socket was overwritten with a new instance, which then wasn't able to bind() anymore the socket which was blocking inside the accept() wasn't accessible anymore, leaving a complete shutdown and restart of the application as the only way to get rid of it. Which leaves me wondering: with no references left to the ServerSocket instance, what would free the socket for a new connection? At what point would the ServerSocket become garbage collected? In general, what are good practices I can follow to avoid this type of bug?

• Web service URL being overwritten with localhost

  - by Jay Heavner

  I have a reference to a web service on a remote server like such... http://10.5.1.121/PersonifyWebServicePPROD/UniversalWebService/default.wsdl The moment I invoke the web service and view its URL property it looks like... http://localhost/PersonifyWebServicePPROD/UniversalWebService/default.asmx Can anyone tell me why it's overwriting the remote server with localhost? The vendor that provided the web service said I have to reference the wsdl and not the asmx in order for it to work. I've tried running it both within IIS and as a web app on the filesystem and neither scenario work. This is on the .Net 3.5 framework.

• UML binary association aggregatee has access to aggregator

  - by user314172

  Firstly, I'd like to thank those who answered my previous question ages ago. Currently I'm engaging more in the design phase UMLs, as this is my first medium scale deployment I'm entrusted with. This is extremely simple, but it bugs me so. If (Component) owns (Manager of Component), and (Manager of Component) has a reference to (Component) through which it manages it; how do you fully describe the relationship? I know it is aggregative, but how do you describe (Manager of Component) possessing a reference/pointer to the (Component) that physically owns the (Manager of Component) ? Example: Lidar owns a LidarManager

• Doesn't Spring really support Interface injection at all?

  - by mrCoder

  Hi I know that Spring doesn't supports Interface injection and I've read that many a times. But today as I came across an article about IOC by Martin Fowler (link), it seems using ApplicationContextAware in Spring is some what similar to the Interface injection. when ever Spring' context reference is required in our Spring bean, we'll implement ApplicationContextAware and will implement the setApplicationContext(ApplicationContext context) method, and we'll include the bean in the config file. Is not this the same as Interface injection, where where telling the Spring to inject (or), say, pass the reference of the context into this bean? Or I m missing something here? Thanks for any information! ManiKanta

• Should every class have its own namespace?

  - by thehouse

  Something that has been troubling me for a while: The current wisdom is that types should be kept in a namespace that only contains functions which are part of the type's non-member interface (see C++ Coding Standards Sutter and Alexandrescu or here) to prevent ADL pulling in unrelated definitions. Does this imply that all classes must have a namespace of their own? If we assume that a class may be augmented in the future by the addition of non-member functions, then it can never be safe to put two types in the same namespace as either one of them may introduce non-member functions that could interfere with the other. The reason I ask is that namespaces are becoming cumbersome for me. I'm writing a header-only library and I find myself using classes names such as project::component::class_name::class_name. Their implementations call helper functions but as these can't be in the same namespace they also have to be fully qualified!
