• ReportServer 2005 Custom Assembly Error

  - by user752083

  We have a reportserver on sql server 2005, it has previously been working on computer X which we are replacing with a computer Y. Computer X only had one default sql instance as our test environment, machine Y is a new machine with 2 sql instances, Y\TEST and Y\DEV. Both machines run Windows Server 2003 and Both have Sql Server 2005 installed together with Report Server We have not currently done any work on the DEV instance, just on the TEST instance. The reportserver is installed for TEST. SSRS previously worked as intended on X machine, and on Y\TEST its working for reports not using any custom code. However for some of the reports we are loading a custom assembly Localization. This assembly currently exists in following folders on server: C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\PublicAssemblies C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\PrivateAssemblies C:\Program Files\Microsoft SQL Server\MSSQL.2\Reporting Services\ReportServer\bin Also in rssrvpolicy.config, the entry for Report_Expressions_Default_Permissions has been changed from Execution to FullTrust (Although this was not necessary on the machine X). When attempting to upload the rdl files through the web interface, we get the following errors: Error while loading code module: ‘Localization, Version=1.0.0.0, Culture=neutral, PublicKeyToken=e302ddd55ecd694a’. Details: Could not load file or assembly 'Localization, Version=1.0.0.0, Culture=neutral, PublicKeyToken=e302ddd55ecd694a' or one of its dependencies. The system cannot find the file specified. (rsErrorLoadingCodeModule) Get Online Help There is an error on line 14 of custom code: [BC30451] Name 'Localization' is not declared.

• Improving field get and set performance with ASM or Javassist

  - by ng

  I would like to avoid reflection in an open source project I am developing. Here I have classes like the following. public class PurchaseOrder { @Property private Customer customer; @Property private String name; } I scan for the @Property annotation to determine what I can set and get from the PurchaseOrder reflectively. There are many such classes all using java.lang.reflect.Field.get() and java.lang.reflect.Field.set(). Ideally I would like to generate for each property an invoker like the following. public interface PropertyAccessor<S, V> { public void set(S source, V value); public V get(S source); } Now when I scan the class I can create a static inner class of PurchaseOrder like so. static class customer_Field implements PropertyAccessor<PurchaseOrder, Customer> { public void set(PurchaseOrder order, Customer customer) { order.customer = customer; } public Customer get(PurchaseOrder order) { return order.customer; } } With these I totally avoid the cost of reflection. I can now set and get from my instances with native performance. Can anyone tell me how I would do this. A code example would be great. I have searched the net for a good example but can find nothing like this. The ASM and Javasist examples are pretty poor also. The key here is that I have an interface that I can pass around. So I can have various implementations, perhaps one with Java Reflection as a default, one with ASM, and one with Javassist? Any help would be greatly appreciated.

• How to manage multiple python versions ?

  - by Gyom

  short version: how can I get rid of the multiple-versions-of-python nightmare ? long version: over the years, I've used several versions of python, and what is worse, several extensions to python (e.g. pygame, pylab, wxPython...). Each time it was on a different setup, with different OSes, sometimes different architectures (like my old PowerPC mac). Nowadays I'm using a mac (OSX 10.6 on x86-64) and it's a dependency nightmare each time I want to revive script older than a few months. Python itself already comes in three different flavours in /usr/bin (2.5, 2.6, 3.1), but I had to install 2.4 from macports for pygame, something else (cannot remember what) forced me to install all three others from macports as well, so at the end of the day I'm the happy owner of seven (!) instances of python on my system. But that's not the problem, the problem is, none of them has the right (i.e. same set of) libraries installed, some of them are 32bits, some 64bits, and now I'm pretty much lost. For example right now I'm trying to run a three-year-old script (not written by me) which used to use matplotlib/numpy to draw a real-time plot within a rectangle of a wxwidgets window. But I'm failing miserably: py26-wxpython from macports won't install, stock python has wxwidgets included but also has some conflict between 32 bits and 64 bits, and it doesn't have numpy... what a mess ! Obviously, I'm doing things the wrong way. How do you usally cope with all that chaos ?e

• Implementing Drag and Drop using MouseListener for custom Components

  - by Chris Lieb

  I am working on a school assignment that requires me to be able to pick up a tile, drag it to a location, then drop it there. I was able to get this working using TransferHandler and a bunch of stuff from the dnd package, but this is not an acceptable way to perform this action for this assignment according to the professor. So, I am trying to achieve the same effect using the MouseListener interface. The basic setup is this: I have a JPanel-derived class called LocationView that contains JLabel-dervived instances of TileView. I need to get events that give me the LocationView that has the mouse pressed on and the LocationView that has the mouse released on. I am proxying mouse events through the TileView to its containing LocationView so that I can properly handle the mousePressed event. I added System.out.println()'s to the mouse listeners for mousePressed and mouseReleased to both LocationView and TileView so that I could observe the events that were being generated. To my surprise, pressing the mouse on Tile A in Location A, then dragging to Location B and releasing would generate a mouse released event for both Tile A and Location A, but not for Location B. I need the mouse released event triggered for only Location B. To try to work around this, I tried implementing a glass pane based off of the FinalGlassPane found at http://weblogs.java.net/blog/2006/09/20/well-behaved-glasspane. After adding the glass pane and adding an event listener for it, I can see that the mouse events are indeed filtering through the glass pane, but the mouse released event is still only being called on the item the mouse was clicked on. Is there a way to have mousePressed and mouseReleased events associated with the same drag action be called on separate components?

• ASP.NET Loading a User Control in a Repeater

  - by user70192

  Hello, I have a Repeater control that loads instances of a custom control I have built. This repeater looks like this: <asp:Repeater ID="myRepeater" runat="server" OnLoad="myRepeater_Load"> <HeaderTemplate> <table border="0" cellpadding="0" cellspacing="0"> </HeaderTemplate> <ItemTemplate> <tr><td><my:CustomControl ID="myControl" runat="server" OnLoad="myControl_Load" /> </td></tr> </ItemTemplate> <FooterTemplate> </table> </FooterTemplate> </asp:Repeater> I bind to the Repeater through the myRepeater_Load event handler. My custom control is used to render an item within the Repeater. Because of this, I am trying to set properties on the custom control during the myControl_Load event handler. However, I do not know how to access the current item during the myControl_Load event. Is there a way I can pass along the current item or access the current item during the myControl_Load event? If so, how? Thank you,

• MongoDB in Go (golang) with mgo: How do I update a record, find out if update was successful and get the data in a single atomic operation?

  - by Sebastián Grignoli

  I am using mgo driver for MongoDB under Go. My application asks for a task (with just a record select in Mongo from a collection called "jobs") and then registers itself as an asignee to complete that task (an update to that same "job" record, setting itself as assignee). The program will be running on several machines, all talking to the same Mongo. When my program lists the available tasks and then picks one, other instances might have already obtained that assignment, and the current assignment would have failed. How can I get sure that the record I read and then update does or does not have a certain value (in this case, an assignee) at the time of being updated? I am trying to get one assignment, no matter wich one, so I think I should first select a pending task and try to assign it, keeping it just in the case the updating was successful. So, my query should be something like: "From all records on collection 'jobs', update just one that has asignee=null, setting my ID as the assignee. Then, give me that record so I could run the job." How could I express that with mgo driver for Go?

• SQL Server Database In Single User Mode after Failover

  - by jlichauc

  Here is a weird situation we experienced with a SQL Server 2008 Database Mirroring Failover. We have a pair of mirrored databases running in high-availability mode and both the principal and mirror showed as synchronized. As part of some maintenance I triggered a manual failover of the principal to the mirror. However after the failover the principal was now in single-user mode instead of the expected "Principal/Synchronized" state we usually get. The database had been in multi-user mode on the previous principal before this had happened. We ended up stopping all applications, restarting the SQL Server instances, and executing "ALTER DATABASE ... SET MULTI_USER" to bring the database back to the expected "Principal/Synchronized" state in a multi-user mode. Question. Does anyone know where SQL Server stores information about whether a database should be in single-user mode or not? I'm wondering if there is some system database or table that has this setting recorded somewhere. In particular we had an incident once with the database on the original principal (the one I was failing over to) where when trying to detach the database it was put into single-user mode. I'm wondering if that setting is cached somewhere and is the reason that SQL Server put it back into single-user mode after a failover.

• Why can't I wrap the ServletRequest when trying to capture JSP Output

  - by Patrick Cornelissen

  I am trying to dispatch in a servlet request handler to the JSP processor and capture the content of it. I am providing wrapper instances for the ServletRequest and ServletResponse, they implement the corresponding HTTPServletRequest/-Response interfaces, so they should be drop-in replacements. All methods are currently passed to the original Servlet Request object (I am planning to modify some of them soon). Additionally I have introduced some new methods. (If you want to see the code: http://code.google.com/p/gloudy/source/browse/trunk/gloudyPortal/src/java/org/gloudy/gloudlet/impl/RenderResponseImpl.java) The HttpServletResponse uses it's own output streams to capture the output. When I try to call request.getRequestDispatcher("/WEB-INF/views/test.jsp").include(request, response); With my request and response wrappers the method returns and no content has been captured. When I tried to pass the original request object it worked! But that's not what I need in the long run... request.getRequestDispatcher("/WEB-INF/views/test.jsp").include(request.getServletRequest(), response); This works. getservletRequest() returns the original Request, given by the servlet container. Does anyone know why this is not working with my wrappers?

• Is there a way to automaticly call all versions of an inherited method?

  - by Eric

  I'm writing a plug-in for a 3D modeling program. I have a custom class that wraps instances of elements in the 3D model, and in turn derives it's properties from the element it wraps. When the element in the model changes I want my class(es) to update their properties based on the new geometry. In the simplified example below. I have classes AbsCurveBasd, Extrusion, and Shell which are all derived from one another. Each of these classes implement a RefreshFromBaseShape() method which updates specific properties based on the current baseShape the class is wrapping. I can call base.RefreshFromBaseShape() in each implementation of RefreshFromBaseShape() to ensure that all the properties are updated. But I'm wondering if there is a better way where I don't have to remember to do this in every implementation of RefershFromBaseShape()? For example because AbsCurveBased does not have a parameterless constructor the code wont even compile unless the constructors call the base class constructors. public abstract class AbsCurveBased { internal Curve baseShape; double Area{get;set;} public AbsCurveBased(Curve baseShape) { this.baseShape = baseShape; RefreshFromBaseShape(); } public virtual void RefreshFromBaseShape() { //sets the Area property from the baseShape } } public class Extrusion : AbsCurveBased { double Volume{get;set;} double Height{get;set;} public Extrusion(Curve baseShape):base(baseShape) { this.baseShape = baseShape; RefreshFromBaseShape(); } public override void RefreshFromBaseShape() { base.RefreshFromBaseShape(); //sets the Volume property based on the area and the height } } public class Shell : Extrusion { double ShellVolume{get;set;} double ShellThickness{get;set;} public Shell(Curve baseShape): base(baseShape) { this.baseShape = baseShape; RefreshFromBaseShape(); } public void RefreshFromBaseShape() { base.RefreshFromBaseShape(); //sets this Shell Volume from the Extrusion properties and ShellThickness property } }

• Dynamic columns/rows

  - by Fuego DeBassi

  Wondering--does anyone know of any good articles explaining the CSS technique allowing multiple instances of a class to flow down the page relative to the items above it. Not explaining it that well. Veerle' Pierter's does it on this page: http://veerle.duoh.com/belgiangraphicdesign Although I'm not sure I want to use a technique like her's that requires entering of the height per element via her EE installation. I made a little graphic of what I am trying to acheive; http://cl.ly/71163510ce9d294f9f33 The key is I need a robust technique for doing it. Something where the markup could be as simple as; <div class="box"> Number 1 </div> <div class="box"> Number 2 </div> <div class="box"> Number 3 </div> <div class="box"> Number 4 </div> <div class="box"> Number 5 </div> ... Would love any pointers in the right direction.

• How should child views of UIScrollView report their bounds for contentSize?

  - by Mike

  I'm looking more for advice on the correct design for a view. What I have is a UIScrollView that contains one or more custom Views I have created. My problem is, who reports to the scrollview what it's contentSize should be? I have the following: UIView +-UIScrollView +-CustomView 1 with dynamic height depending on data +-CustomView 2 with dynamic Height depending on data The UIViewController creates new instances of the custom views with data and then adds them as subviews to the UIScrollView. The problem I'm having is how to set the value of the scrollview's contentSize? Right now, I'm not doing that and the contents of the scrollview are clipped with no scrolling possible. Should the custom view call [parent setContentSize:] in its drawRect:? Should the UIViewController query the custom view after creation to get its bounds and then call setContentSize? Should I subclass the UIScrollView to override addSubView to query each subview's height? Is there something else I'm missing? I hope I explained that properly. I'm new to this and still getting a handle on things.

• Model binding & derived model classes

  - by Richard Ev

  Does ASP.NET MVC offer any simple way to get model binding to work when you have model classes that inherit from others? In my scenario I have a View that is strongly typed to List<Person>. I have a couple of classes that inherit from Person, namely PersonTypeOne and PersonTypeTwo. I have three strongly typed partial views with names that match these class names (and render form elements for the properties of their respective models). This means that in my main View I can have the following code: <% for(int i = 0; i < Model.Count; i++) { Html.RenderPartial(Model[i].GetType().Name, Model[i]); } %> This works well, apart from when the user submits the form the relevant controller action method just gets a List<Person>, rather than a list of Person, PersonTypeOne and PersonTypeTwo. This is pretty much as expected as the form submission doesn't contain enough information to tell the default model binder to create any instances of PersonTypeOne and PersonTypeTwo classes. So, is there any way to get such functionality from the default model binder?

• Accessing the stringValue from NSTextFields on different NIBs

  - by Kyle Zaragoza

  I'm having an extremely difficult time trying to access information from an object (e.g. an NSTextField) that is located on a NIB other than my "MainMenu.nib". My current setup: I have a MainMenu.xib that contains only a toolbar at the top and an NSView. I have four other .xib files containing custom NSViews and each of their File Owner's are assigned to a NSViewController subclass which I have created for each. My MainMenu.xib contains an object that is set to my WindowController subclass that takes care of swapping the fours views into the NSView on my MainMenu.xib. All of this works fantastic. Where I have a problem: I have another class that acts as the brains to my application which sends and receives data from an online server, all of the methods I have created rely on inputs from the user that are located on the individual .xibs that swap into my MainMenu.xib's NSview. Unfortunately I have no idea on how to grab the information from the NSTextFields, textViews, etc. that are located on my individual .xib files. What I've tried: I have tried setting the File Owner's of the four individual .xibs to my "brains" class and connecting outlets defined in my "brains".h, but when I call [textField stringValue] I receive a NULL response. I'm thinking this is because I'm creating multiple instances of my "brains" class but not totally sure. Any help on accessing information from textFields from other nibs would be a great benefit, thanks in advance.

• MySQL database design question

  - by Greelmo

  I'm trying to weigh the pros and cons of a database design, and would like to get some feedback as to the best approach. Here is the situation: I have users of my system that have only a few required items (username, password). They can then supply a lot of optional information. This optional information continues to grow as the system grows, so I want to do it in such a way that adding new optional information is easy. Currently, I have a separate table for each piece of information. For example, there's a table called 'names' that holds 'user_id', 'first_name', and 'last_name'. There's 'address', 'occupation', etc. You get the drift. In most cases, when I talk to my database, I'm looking only for users with one particular qualifier (name, address, etc.). However, there are instances when I want to see what information a user has set. The 'edit account' page, for example, must run queries for each piece of information it wants. Is this wasteful? Is there a way I can structure my queries or my database to make it so I never have to do one query for each piece of information like that without getting my tables to huge? If i want to add 'marital status', how hard will that be if I don't have a one-table-per-attribute system? Thanks in advance.

• Regex for removing certain variable numeric values from some text

  - by stephemurdoch

  I want to substitute all 4 instances of the number 300 from the code below, with 470. <div> <object width="300" height="300"> <embed src="link-removed" width="300" height="300"></embed> </object> <p> <a href="another-link">link</a> </p> </div> The width and height of the code being pasted might not always be 300 by 300. So I figure I probably need a regular expression that subs any numeric value that follows the strings "width=" and "height=", whilst remembering to account for the quotations marks that surround the number. Can anyone tell me if that's the best way, and if so, what would be the best regex? In case it matters, the code being pasted is stored as "text" in the db rather than as a string, as it's quite lengthy (i've removed a few hundred chars from what you see pasted here)...

• jmap -histo is missing a lot of memory

  - by ripper234

  I have a JVM with 12 gigs of total RAM, out of which 7 GB is allocated to the old generation. There seems to be some memory leak, because almost the entire old gen is full, and will not release when I schedule a GC (the process is not doing anything else at that time). A jmap -histo dump only reveals less than 1 gigabyte worth of objects. Where are the missing 6 gigs? What better tool do you propose for diagnosing this? Here is the top of the jmap output: num #instances #bytes class name ---------------------------------------------- 1: 429853 68725736 <constMethodKlass> 2: 429853 51594040 <methodKlass> 3: 37503 49611368 <constantPoolKlass> 4: 37503 31109576 <instanceKlassKlass> 5: 191716 28019968 [C 6: 32573 26933152 <constantPoolCacheKlass> 7: 86158 13789560 [I 8: 53532 11244232 [B 9: 284 10507216 [J 10: 137608 7210664 <symbolKlass> 11: 203072 6498304 java.lang.String 12: 10132 5219512 <methodDataKlass> 13: 39694 4128176 java.lang.Class 14: 55713 3792816 [S 15: 61816 3141936 [[I 16: 90109 2883488 java.util.HashMap$Entry

• Naming multi-instance performance counters in .NET

  - by Roger Lipscombe

  Most multiple instance performance counters in Windows seem to automatically(?) have a #n on the end if there's more than one instance with the same name. For example: if, in Perfmon, you look under the Process category, you'll see: ... dwm explorer explorer#1 ... I have two explorer.exe processes, so the second counter has #1 appended to its name. When I attempt to do this in a .NET application: I can create the category, and register the instance (using the PerformanceCounterCategory.Create that takes a CounterCreationDataCollection). I can open the counter for write and write to it. When I open the counter a second time, it opens the same counter. This means that I have two applications fighting over the counters. The documentation for PerformanceCounter.InstanceName states that # is not allowed in the name. So: how do I have multiple-instance performance counters that are actually multiple instance? And where the second (and subsequent) instances get #n appended to the name? That is: I know that I can put the process ID (e.g.) on the instance name. This works, but has the unfortunate side effect that restarting the process results in a new PID, and Perfmon continues monitoring the old counter.

• Assembly unavailable after Web.config change

  - by tags2k

  I'm using a custom framework that uses reflection to do a GetTypeByName(string fullName) on the fully-qualified type name that it gets from the database, to create an instance of said type and add it to the page, resulting in a standard modular kind of thing. GetTypeByName is a utility function of mine that simply iterates through Thread.GetDomain().GetAssemblies(), then performs an assembly.GetType(fullName) to find the relevant type. Obviously this result gets cached for future reference and speed. However, I'm experiencing some issues whereby if the web.config gets updated (and, in some scarier instances if the application pool gets recycled) then it will lose all knowledge of certain assemblies, resulting in the inability to render an instance of the module type. Debugging shows that the missing assembly literally does not exist in the current thread assemblies list. To get around this I added a second check which is a bit dirty but recurses through the /bin/ directory's DLLs and checks that each one exists in the assemblies list. If it doesn't, it loads it using Assembly.Load and fixing the context issue thanks to 'Solving the Assembly Load Context Problem'. This would work, only it seems that (and I'm aware this shouldn't be possible) some projects still have access to the missing assembly, for example my actual web project rather than the framework itself - and it then complains that duplicate references have been added! Has anyone ever heard of anything like this, or have any ideas why an assembly would simply drop out of existence on a config change? Short of a solution, what is the most elegant workaround to get all the assemblies in the bin to reload? It needs to be all in one "hit" so that the site visitors don't see any difference other than a small delay, so an app_offline.htm file is out of the question. Programatically renaming a DLL in the bin and then naming it back does work, but requires "modify" permissions for the IIS user account, which is insane. Thanks for any pointers the community can gather!

• Is it possible to accept a button tag to be in some range iphone sdk

  - by neha

  Hi all, In my application I'm doing dynamic resizing of cells and label in it depending upon the text in it. I'm adding button to cells in uitableview. I'm taking the label instance and button instance in a new label and button variable respectively and setting their frames to arrange them properly after resizing. if(cel==nil) { //some code original_label=[[UILabel alloc]init]; original_label.tag=111; //SOME MORE CODE GOES HERE original_button=[[UIButton alloc]init]; original_button.tag=222; //SOME MORE CODE GOES HERE } new_label=(UILabel *) [cell viewWithTag:111]; //This' how I'm taking the label instance on cell and below button instance on cell in new variables new_button = (UIButton * ) [cell viewWithTag:222]; Earlier I kept the tags of all the buttons on cells same, so it was easier to get button instances on cells properly and were being arranged properly. But now I want to recognize these buttons separately as I'm adding some functionality on button_click. I'm giving the buttons that are added to the cells incremental tags[1,2,3...9 and so on]. Now, how can I take these button tags in some range like[suppose 1-9]? Can anybody help? Thanks in advance.

• Partial Classes - are they bad design?

  - by dferraro

  Hello, I'm wondering why the 'partial class' concept even exists in .NET. I'm working on an application and we are reading a (actually very good) book relavant to the development platform we are implementing at work. In the book he provides a large code base /wrapper around the platform API and explains how he developed it as he teaches different topics about the platform development. Anyway, long story short - he uses partial classes, all over the place, as a way to fake multiple inheritence in C# (IMO). Why he didnt just split the classes up into multiple ones and use composition is beyond me. He will have 3 'partial class' files to make up his base class, each w/ 3-500 lines of code... And does this several times in his API. Do you find this justifiable? If it were me, I'd have followed the S.R.P. and created multiple classes to handle different required behaviors, then create a base class that has instances of these classes as members (e.g. composition). Why did MS even put partial class into the framework?? They removed the ability to expand/collapse all code at each scope level in C# (this was allowed in C++) because it was obviously just allowing bad habits - partial class is IMO the same thing. I guess my quetion is: Can you explain to me when there would be a legitimate reason to ever use a partial class? I do not mean this to be a rant / war thread. I'm honeslty looking to learn something here. Thanks

• Connecting an overloaded PyQT signal using new-style syntax

  - by Claudio

  I am designing a custom widget which is basically a QGroupBox holding a configurable number of QCheckBox buttons, where each one of them should control a particular bit in a bitmask represented by a QBitArray. In order to do that, I added the QCheckBox instances to a QButtonGroup, with each button given an integer ID: def populate(self, num_bits, parent = None): """ Adds check boxes to the GroupBox according to the bitmask size """ self.bitArray.resize(num_bits) layout = QHBoxLayout() for i in range(num_bits): cb = QCheckBox() cb.setText(QString.number(i)) self.buttonGroup.addButton(cb, i) layout.addWidget(cb) self.setLayout(layout) Then, each time a user would click on a checkbox contained in self.buttonGroup, I'd like self.bitArray to be notified so I can set/unset the corresponding bit in the array. For that I intended to connect QButtonGroup's buttonClicked(int) signal to QBitArray's toggleBit(int) method and, to be as pythonic as possible, I wanted to use new-style signals syntax, so I tried this: self.buttonGroup.buttonClicked.connect(self.bitArray.toggleBit) The problem is that buttonClicked is an overloaded signal, so there is also the buttonClicked(QAbstractButton*) signature. In fact, when the program is executing I get this error when I click a check box: The debugged program raised the exception unhandled TypeError "QBitArray.toggleBit(int): argument 1 has unexpected type 'QCheckBox'" which clearly shows the toggleBit method received the buttonClicked(QAbstractButton*) signal instead of the buttonClicked(int) one. So, the question is, how can we specify, using new-style syntax, that self.buttonGroup emits the buttonClicked(int) signal instead of the default overload - buttonClicked(QAbstractButton*)?

• Is it normal for C++ static initialization to appear twice in the same backtrace?

  - by Joseph Garvin

  I'm trying to debug a C++ program compiled with GCC that freezes at startup. GCC mutex protects function's static local variables, and it appears that waiting to acquire such a lock is why it freezes. How this happens is rather confusing. First module A's static initialization occurs (there are __static_init functions GCC invokes that are visible in the backtrace), which calls a function Foo(), that has a static local variable. The static local variable is an object who's constructor calls through several layers of functions, then suddenly the backtrace has a few ??'s, and then it's is in the static initialization of a second module B (the __static functions occur all over again), which then calls Foo(), but since Foo() never returned the first time the mutex on the local static variable is still set, and it locks. How can one static init trigger another? My first theory was shared libraries -- that module A would be calling some function in module B that would cause module B to load, thus triggering B's static init, but that doesn't appear to be the case. Module A doesn't use module B at all. So I have a second (and horrifying) guess. Say that: Module A uses some templated function or a function in a templated class, e.g. foo<int>::bar() Module B also uses foo<int>::bar() Module A doesn't depend on module B at all At link time, the linker has two instances of foo<int>::bar(), but this is OK because template functions are marked as weak symbols... At runtime, module A calls foo<int>::bar, and the static init of module B is triggered, even though module B doesn't depend on module A! Why? Because the linker decided to go with module B's instance of foo::bar instead of module A's instance at link time. Is this particular scenario valid? Or should one module's static init never trigger static init in another module?

• Using data binding on value which is a FrameworkElement

  - by JaredPar

  One of my data sources produces a collection of values which are typed to the following interface public interface IData { string Name { get; } FrameworkElement VisualElement { get; } } I'd like to use data binding in WPF to display a collection of IData instances in a TabControl where the Name value becomes the header of the tab and the VisualElement value is displayed as the content of the corresponding tab. Binding the header is straight forward. I'm stuck though on how to define a template which allows me to display the VisualElement value. I've tried a number of solutions with little success. My best attempt is as follows. <TabControl ItemsSource="{Binding}"> <TabControl.ItemTemplate> <DataTemplate> <Label Content="{Binding Name}"/> </DataTemplate> </TabControl.ItemTemplate> <TabControl.ContentTemplate> <DataTemplate> How do I display VisualElement here? </DataTemplate> </TabControl.ContentTemplate> </TabControl> I'm still very new to WPF so I could be missing the obvious here.

• Bulk insert of component collection in Hibernate?

  - by edbras

  I have the mapping as listed below. When I update a detached Categories item (that doesn't contain any Hibernate class as it comes from a dto converter) I notice that Hibernate will first delete ALL employer wages instances (the collection link) and then insert ALL employer wage entries ONE-BY-ONE :(... I understand that it has to delete and then insert all entries as it was completely detached. BUT, what I don't understand, why is Hibernate NOT inserting all the entries through bulk-insert?.. That is: inserting all the employer wage entries all in one SQL statement ? How can I tell Hibernate to use bulk-insert? (if possible). I tried playing with the following value but didn't see any difference: hibernate.jdbc.batch_size=30 My mapping snippet: <class name="com.sample.CategoriesDefault" table="dec_cats" > <id name="id" column="id" type="string" length="40" access="property"> <generator class="assigned" /> </id> <component name="incomeInfoMember" class="com.sample.IncomeInfoDefault"> <property name="hasWage" type="boolean" column="inMemWage"/> ... <component name="wage" class="com.sample.impl.WageDefault"> <property name="hasEmployerWage" type="boolean" column="inMemEmpWage"/> ... <set name="employerWages" cascade="all-delete-orphan" lazy="false"> <key column="idCats" not-null="true" /> <one-to-many entity-name="mIWaEmp"/> </set> </component> </component> </class>
