• VS 2008 Profiler - Caller/Callee view showing bottom of stack

  - by Ncc

  Hello, I am currently trying to profile a class contained in a different assembly. To do this I created a small console application which calls into the public entry point of the class I want to profile. This enrty point is called Run(). This is working fine when I run my Console application in Debug mode and I can step into the Run() method. The Run() method calls a variety of other methods in its own assembly and other assemblies. However, when I create a new profiler of type "Instrumentation" in VS 2008, and run the profiler, the report shows my Main() function calling Run(), but in turn, when viewing the Caller/Callee report for my Run() method the report shows that the Run() method is the bottom of the stack. This is clearly not the case - could anyone please suggest why this is happening? Thanks.

• Query to return internal details about stored function in SQL Server database

  - by Anthony

  I have been given access to a SQL Server database that is currently used by 3rd party app. As such, I don't have any documentation on how that application stores the data or how it retrieves it. I can figure a few things out based on the names of various tables and the parameters that the user-defined functions takes and returns, but I'm still getting errors at every other turn. I was thinking that it would be really helpful if I could see what the stored functions were doing with the parameters given to return the output. Right now all I've been able to figure out is how to query for the input parameters and the output columns. Is there any built-in information_schema table that will expose what the function is doing between input and output?

• Check which nodes of Beowulf HPC cluster system are free from PHP app?

  - by Skuja

  I am working on my diploma thesis project. I have access to 32Node Dell poweredge HPC cluster system with Linux(Debian i think) installed on it. My first goal is to create web (PHP) app where logged users could see free and busy nodes, turn them on and off. I am planning to do something like this - write some cron daemon that would run every 30seconds or other interval, and it could run ping utility for each node to find out if it is on or off, then write results to some file. Then from my web app i could read the info. Will it be a good solution? What existing for node management solutions are there?

• Default Accessor Needed: Custom ConfigurationSection

  - by Mark

  I am totally confused by a simple Microsoft error message. When I run XSD.exe against an assembly that contains a custom ConfigurationSection (which in turn utilizes a custom ConfigurationElement and a custom ConfigurationElementCollection, as well as several ConfigurationProperties), I get the following error message: Error: There was an error processing 'Olbert.Entity.Utils.dll'. There was an error reflecting type 'Olbert.Entity.DatabaseConnection'. You must implement a default accessor on System.Configuration.ConfigurationLockCollection because it inherits from ICollection. Yet the class in question has a default accessor: public object this[int idx] { get { return null; } set { } } I realize the above doesn't do anything, but I don't need to access the element's properties by index. I'm just trying to work around the error message. So what's going on?

• JavaEE Application Server or Lightweight Container?

  - by Jeff Storey

  Let me preface this by saying this is not an actual situation of mine but I'm asking this question more for my own knowledge and to get other people's inputs here. I've used both Spring and EJB3/JBoss, and for the smaller types of applications I've built, Spring (+Tomcat when needed) has been much simpler to use. However, when scaling up to larger applications that require things like load balancing and clustering, is Spring still a viable solution? Or is it time to turn to a solution like EJB3/JBoss when you start to get big enough to need that? I'm not sure if I've scoped the problem well enough to get a good answer, so please let me know. Thanks, Jeff

• Disable a style in VCL application

  - by Martin

  I am adding the a VCL style into my application but am also giving the users an option to turn this off but I cannot figure out how to do this globally at runtime. Setting "TStyleManager.AutoDiscoverStyleResources := false" almost works but it pops up with an error message saying "Style {style set} not found" but after dismissing the message does exactly what I want. This code I would expect to work but does not... if (not ParamObj.UseDarkStyle) then begin //TStyleManager.AutoDiscoverStyleResources := false; TStyleManager.SetStyle(TStyleManager.SystemStyle); end; I also tried (originally) TStyleManager.TrySetStyle('Windows'); but this also does not work. I have tried this both sides of "Application.Initialize;" with no difference What am I missing? Thanks in advance, Martin

• Ruby module_function, invoking module's private method, invoked in class method style on module shows error

  - by Jignesh

  test_module.rb module MyModule def module_func_a puts "module_func_a invoked" private_b end module_function :module_func_a private def private_b puts "private_b invoked" end end class MyClass include MyModule def test_module module_func_a end end Invoking module function from class c = MyClass.new c.test_module Output 1: $ ruby test_module.rb module_func_a invoked private_b invoked Invoking module function on module in class method style ma = MyModule.module_func_a Output 2: module_func_a invoked test_module.rb:5:in `module_func_a': undefined local variable or method `private_b' for MyModule:Module (NameError) from test_module.rb:31 As can be seen from the Output 1 and Output 2 when including the module in a class, no issue occurs when a module's private method gets invoked from a module function while in case when directly invoking the module function on the module in class method style the module's private method, invoked from module function, is not found. Can anybody make me understand the reason behind above behavior and whether invoking module function (which in turn invokes module's private method) on module in class method style is possible or not? If possible, then what rectifications are required in my code to do the same? Thanks, Jignesh

• .net 4 Chart Control - Hide labels in pie chart

  - by Ricardo Deano

  Hello all. Am I going mad/blind? Probably a combination of the two. How does one go about removing the data labels from a pie chart with the new chart control in .net 4? I can get these to display as tooltips absolutely fine, but ultiamtely I'd like the labels not to be present as it looks rather busy. I've searched previous answers and seen code behind resolutions but surely there must be some sort of code infront option to turn these labels off? Apologies for being thick/blind.

• How to represent double values as circles in a 2d matrix in java

  - by marco

  Hello, so I want to write a matrix explorer which enables me to reorder rows and columns of a matrix. For this porpouse I used the Jtable class. Now the problem that I have is that it is very difficult to reorder a matrix by looking at double values, so I would like to print the matrix not with the double values but with circles in which the radius of the circle represents the value. So that I can tell the difference between big values and small values quicker. Anybody has any idea how I can turn this double values into filled circles with JTable or any table class for that matter?

• Nothing = String.Empty (Why are these equal?)

  - by Ek0nomik

  I find it very puzzling that null equals String.Empty in VB.NET. There must be an explanation for it that I'm not understanding. Somehow, when the equality of String.Empty (which has an object type of string) is tested against Nothing (which has no type) the test returns true. It just seems like a turn around in logic to me. In SQL if I were to compare an empty char or varchar against a null value, the test wouldn't return true. A null value is not the same as an empty string in this case. Yet in VB.NET they are equal. I'd love it if someone could provide a good explanation around this.

• Disabling a CellEditingTemplate programmatically in in a Silverlight DataGrid

  - by bplus

  I have a Silverlight Datagrid, I'd like to make certain cells readonly programmatically. Specifically I have a CellEditingTemplate, I'd like to turn the cell editing off or on depending on the value of CategoryTypeName (see the xmal below). <local:DataGridTemplateColumn Header="Category" > <local:DataGridTemplateColumn.CellTemplate> <DataTemplate> <TextBlock Text="{Binding CategoryTypeName}"/> </DataTemplate> </local:DataGridTemplateColumn.CellTemplate> <local:DataGridTemplateColumn.CellEditingTemplate> <DataTemplate> <ComboBox Width="90" x:Name="CategoryCombo" ItemsSource="{Binding CategoryTypes}" DisplayMemberPath="Name" SelectionChanged="CategoryCombo_SelectionChanged" /> </DataTemplate> </local:DataGridTemplateColumn.CellEditingTemplate> </local:DataGridTemplateColumn> Is there a way to do this? Any help would be very much appreciated. Thanks in advance.

• RecursiveIterator: used to explode tree structure, or only flatten?

  - by Stephen J. Fuhry

  There are tons of examples of using the RecursiveIterator to flatten a tree structure.. but what about using it to explode a tree structure? Is there an elegant way to use this, or some other SPL library to recursively build a tree (read: turn a flat array into array of arbitrary depth) given a table like this: SELECT id, parent_id, name FROM my_tree EDIT: You know how you can do this with Directories? $it = new RecursiveDirectoryIterator("/var/www/images"); foreach(new RecursiveIteratorIterator($it) as $file) { echo $file . PHP_EOL; } .. What if you could do something like this: $it = new RecursiveParentChildIterator($result_array); foreach(new RecursiveIteratorIterator($it) as $group) { echo $group->name . PHP_EOL; echo implode(PHP_EOL, $group->getChildren()) . PHP_EOL . PHP_EOL; } :END EDIT

• Looking For A Good HTML Templater for PHP

  That's an HTML templater, not a php templater, not java or whatever. I am looking for something like HAML for PHP. I tried the 2 projects for PHP, PHAML and PHPHaml both of which are suffering from serious bugs. Do you know of any good html templater out there, preferably for PHP? EDIT I''m looking for something that can turn this <h1>Heading</h1> <p>entry</p> <blockquote>quote</blockquote> to something like this h1 : heading p : entry blockquote : quote something like what phphaml does

• How to create a controllable flip effect (flip as far (and fast) as you drag) of an UIView

  - by allisone

  I have a card (a flashcard you could say) What I can do: On fingersweeping over the flashcard the card gets turned. It's happening by detecting touchesBegan and touchesMoved and then I do stuff like [UIView beginAnimations:@"View Flip" context:nil]; [UIView setAnimationDuration:0.5]; [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut]; if (left) { [UIView setAnimationTransition: UIViewAnimationTransitionFlipFromLeft forView:self.flashCardView cache:YES]; }else{ [UIView setAnimationTransition: UIViewAnimationTransitionFlipFromRight forView:self.flashCardView cache:YES]; } What I can't do (but want to): I want to somehow drag the flip. Imagine this, you have a flashcard and you think you know the answer, you start flipping the card around because you want to see if you are correct, but then... no stop... you hesitate, turn back the card to the way it was, rethink, get the real answer and then finally flip to see that you were right to hesitate. Now I only have: once you start flipping, you can't stop it.

• How am I supposed to deploy an ASP.NET MVC 4.0 website?

  - by Matt Frear

  What's the recommended way to deploy a website created with ASP.NET 4.0 and Visual Studio 2010? I've previously always added a web setup project to my solution, and used that to create an MSI, even for small applications. But when I build a web setup project in VS2010 it kind of works but some stuff still seems broken: 1. I need to turn on IIS 6 Compatibility on a Win 2008 R2 box to get the msi to run. 2. The msi includes web.config, web.debug.config, and web.release.config. I thought VS's web.config transformations was supposed to take care of that. -Matt

• JAXB appending unneeded namespace declarations to tags

  - by jb

  I'm implementing a homebrew subprotocol of XMPP, and i'm using combination of StAX and JAXB for parsing/marshalling mesages. And when I marshall a message I end up with loads of unneded namespace declarations: <ns2:auth xmlns:ns2="urn:ietf:params:xml:ns:ilf-auth" xmlns:ns4="ilf:iq:experiment:power" xmlns:ns3="ilf:iq:experiment:init" xmlns:ns5="ilf:iq:experiment:values" xmlns:ns6="ilf:iq:experiment:result" xmlns:ns7="ilf:iq:experiment:stop" xmlns:ns8="ilf:iq:experiment:end"> compton@ilf</ns2:auth> instead of: <ns:auth xmlns:ns="urn:ietf:params:xml:ns:ilf-auth>compton@ilf</ns:auth> Is there any way to turn that of? All these namespaces are used in different messages that get marshalled/unmarshalled by JAXB, but every message uses one namespace. PS. I am not an XML expert please dont rant me if I did some stupid mistake ;)

• Disable the mouse click event of a button placed inside a listbox item

  - by Malcolm

  I have a button placed inside a listbox item and i have style defined fro that button where i have two images and on mouse hover i change the image. Now the problem is I am handling the listbox mouse event and when click the button the listbox mouse event doesn't fires. I tried to make the property of button ishittestvisisble=false And now if i click on button the listbox mouse event fires but the problem is the two images placed inside the styling of button don't apply as they are the child of button and by default their ishittestvisible also turn out to be false. So any suggestion or idea will be helpfull ....tx in advance...

• MVVM - several workspaces in a workspace seems not to make sense...

  - by msfanboy

  So how do you display complex aggregated ViewModels whose Models have relations to each other? NO wpf disciple ever spoke about that, guess why its not possible... Do you think thats true? Don`t understand me? Look: A CustomerViewModel has many OrderViewModel and those many ProductViewModel. You have 3 Workspaces to enter the new data for all 3 ViewModels AND you have 3 listboxes/combobo/datagrid to multiselect Collections of type = customerVMs, orderVMs and productVM`s. That the UI makes sense to the user he should not need to turn off/on the workspace every new customer/order/product is added what is a bad user experience, how do you do this typical LOB application requirement?

• FileReference and HttpService Browse Image Modify it then Upload it

  - by user177787

  Hello, I am trying to do an image uploader, user can: - browse local file with button.browse - select one and save it as a FileReference. - then we do FileReference.load() then bind the data to our image control. - after we make a rotation on it and change the data of image. - and to finish we upload it to a server. To change the data of image i get the matrix of the displayed image and transform it then i re-use the new matrix and bind it to my old image: private function TurnImage():void { //Turn it var m:Matrix = _img.transform.matrix; rotateImage(m); _img.transform.matrix = m; } Now the mater is that i really don't know how to send the data as a file to my server cause its not stored in the FileReference and data inside FileReference is readOnly so we can't change it or create a new, so i can't use .upload();. Then i tried HttpService.send but i can't figure out how you send a file and not a mxml.

• How do I do automatic data serialization of data objects in Haskell

  - by Adam Gent

  One of the huge benefits in languages that have some sort of reflection/introspecition is that objects can be automatically constructed from a variety of sources. For example in Java I can use the same objects for persisting to a db (with Hibernate) serializing to XML (with JAXB) or serializing to JSON (json-lib). You can do the same in Ruby and Python also usually following some simple rules for properties or annotations for Java. Thus I don't need lots "Domain Transfer Objects". I can concentrate on the domain I am working in. It seems in very strict FP like Haskell and Ocaml this is not possible. Particularly Haskell. The only thing I have seen is doing some sort of preprocessing or meta-programming (ocaml). Is it just accepted that you have to do all the transformations from the bottom upwards? In other words you have to do lot of boring work to turn a data type in haskell into JSON/XML/DB Row object and back again into a data object.

• Does anyone change the Visual Studio default bracing style in C# - Is there a standard?

  - by El Ronnoco

  I find the default bracing style a bit wasteful on line count eg... function foo() { if (...) { ... } else { ... } } would, if I was writing in JavaScript for example be written like... function foo() { if (...) { ... } else { ... } } ...which I understand may also not be to peoples' tastes. But the question(s) is/are do you turn off the VS formatting style and use your own rules? What is the opinion of this in the industry when many people are working on the same code-base? Is it better just to stick to the default just for simplicity/uniformity?

• Batch file: Extracting substring from input parameter to use in IF statement

  - by Neomoon

  This is a very basic example of what I am trying to implement in a more complex batch file. I would like to extract a substring from an input parameter (%1) and branch based on if the substring was found or not. @echo off SETLOCAL enableextensions enabledelayedexpansion SET _testvariable=%1 SET _testvariable=%_testvariable:~4,3% ECHO %_testvariable% IF %_testvariable%=act CALL :SOME IF NOT %_testvariable%=act CALL :ACTION :SOME ECHO Substring found GOTO :END :ACTION ECHO Substring not found GOTO :END ENDLOCAL :END This is what my ouput looks like: C:\>test someaction act =act was unexpected at this time. If possible I would like to turn this in to a IF/ELSE statement and evaluate directly from %1. However I have not had success with either.
