• Help, I need to debug my BrowserHelperObject (BHO) (in C++) after a internet explorer 8 crash in Rel

  - by BHOdevelopper

  Hi, here is the situation, i'm developping a Browser Helper Object (BHO) in C++ with Visual Studio 2008, and i learned that the memory wasn't managed the same way in Debug mode than in Release mode. So when i run my BHO in debug mode, internet explorer 8 works just fine and i got no erros at all, the browser stays alive forever, but as soon as i compile it in release mode, i got no errors, no message, nothing, but after 5 minutes i can see through the task manager that internet explorer instances are just eating memory and then the browser just stop responding every time. Please, I really need some hint on how to get a feedback on what could be the error. I heard that, often it was happening because of memory mismanagement. I need a software that just grab a memory dump or something when iexplorer crashes to help me find the problem. Any help is appreciated, I'll be looking for responses every single days, thank you.

• can't save form content to database, help plsss!!

  - by dana

  i'm trying to save 100 caracters form user in a 'microblog' minimal application. my code seems to not have any mystakes, but doesn't work. the mistake is in views.py, i can't save the foreign key to user table models.py looks like this: class NewManager(models.Manager): def create_post(self, post, username): new = self.model(post=post, created_by=username) new.save() return new class New(models.Model): post = models.CharField(max_length=120) date = models.DateTimeField(auto_now_add=True) created_by = models.ForeignKey(User, blank=True) objects = NewManager() class NewForm(ModelForm): class Meta: model = New fields = ['post'] # widgets = {'post': Textarea(attrs={'cols': 80, 'rows': 20}) def save_new(request): if request.method == 'POST': created_by = User.objects.get(created_by = user) date = request.POST.get('date', '') post = request.POST.get('post', '') new_obj = New(post=post, date=date, created_by=created_by) new_obj.save() return HttpResponseRedirect('/') else: form = NewForm() return render_to_response('news/new_form.html', {'form': form},context_instance=RequestContext(request)) i didn't mention imports here - they're done right, anyway. my mistake is in views.py, when i try to save it says: local variable 'created_by' referenced before assignment it i put created_py as a parameter, the save needs more parameters... it is really weird help please!!

• Design Documents for Python/Django?

  - by british_trader

  After working on a Django project for a while, I now have to do some design documents for it (UML type stuff). However the code doesn't have classes, but instead uses views.py with modules in it... What would be the best way to show the design of my application from the initial __init__.py, to the urls.py where the HTML requests are then filtered to the specific urls.py in each of the packages and then handled by the views.py? i.e. django-app urls.py views.py settings.py manager.py __init__.py django-package urls.py views.py

• How to read changed values with native query during one transaction? (Spring and JPA)

  - by knarf1983

  We have container transaction with Spring and JPA (Hibernate). I need to make an update on a table to "flag" some rows via native statements. Then we insert some rows via EntityManager from JPATemplate to this table. After that, we need to calculate changes in the table via native statement (with Oracle's union and minus, complex groups...) I see that changes from step 1 and 2 are not commited and thats why the statement from 3 fails. I already tried with transaction propagation REQUIRES_NEW, EntityManager.flush... Didn't work. 1) update SOMETABLE acolumn = somevalue (native) 2) persist some values into SOMETABLE (via entity manager) 3) select values from SOMETABLE Is there a possibility to read the changes from step 1 and 2 in step 3?

• How can I get the "Latency" of a process that has a TCP connection open?

  - by Dave

  Hello, I am looking to get the "Latency" field of a TCP connection. I notice windows Resource Monitor has this field, and I was wondering if there was a way I can find it. Preferrably without using WMI. If you are unsure what field I am talking about, open Task Manager, goto the Performance tab and hit the Resource Monitor button. Once Resource Monitor is open, expand the TCP Connections area and you will see a Latency field. Is there anyway to access this programatically? Thanks!

• Zend Framework 2 without MVC

  - by Luke

  I'm currently using Zend Framework 2 for all my web tier development using the MVC module that's shipped with the framework. However, I want to implement my business logic in a separate layer, call it the business tier which is a non HTTP layer and expose it through AMQP, and I'd like to reuse my knowledge of PHP for implementing this. Since there is a lot of "stuff" that I need in this business layer such as configuration, a service manager, database access, etc, etc, I'd like to use all the goodies shipped with Zend Framework 2 for this. Are there any examples or tutorials out there on how to build a Zend Framework 2 application that is not build for the web tier and doesn't require the MVC module?

• using arrays to get best memory alignment and cache use, is it necessary?

  - by Alberto Toglia

  I'm all about performance these days cause I'm developing my first game engine. I'm no c++ expert but after some research I discovered the importance of the cache and the memory alignment. Basically what I found is that it is recommended to have memory well aligned specially if you need to access them together, for example in a loop. Now, In my project I'm doing my Game Object Manager, and I was thinking to have an array of GameObjects references. meaning I would have the actual memory of my objects one after the other. static const size_t MaxNumberGameObjects = 20; GameObject mGameObjects[MaxNumberGameObjects]; But, as I will be having a list of components per object -Component based design- (Mesh, RigidBody, Transformation, etc), will I be gaining something with the array at all? Anyway, I have seen some people just using a simple std::map for storing game objects. So what do you guys think? Am I better off using a pure component model?

• Interview Question: What are the characteristics of a good programmer?

  - by froadie

  I was asked this question on an interview a few months ago - "What would you say are the characteristics of a good programmer?" What would you answer to this?

• Visual Studio 2010 Not Recognizing Unit Test

  - by jmease

  In an existing solution I added a new Test Project. In my Test Project .cs file I have a class decorated with the [TestClass] attribute and a method decorated with the [TestMethod] attribute. I have verified that in Configuration Manager the build check box is checked for the Test Project (as my google search has revealed was the problem for others with this issue). I have set Test Project as my start up project for the solution. When I try to start the test I get "Can not start test project because the project does not contain any tests". I am really new to unit testing. What am I missing?

• How to force Maven to download maven-metadata.xml from the central repository?

  - by Alceu Costa

  What I want to do is to force Maven to download the 'maven-metadata.xml' for each artifact that I have in my local repository. The default Maven behaviour is to download only metadata from remote repositories (see this question). Why I want to do that: Currently I have a remote repository running in a build machine. By remote repository I mean a directory located in the build machine that contains all dependencies that I need to build my Maven projects. Note that I'm not using a repository manager like Nexus, the repository is just a copy of a local repository that I have uploaded to my build machine. However, since my local repository did not contain the 'maven-metadata.xml' files, these metadata files are also missing in the build machine repository. If I could retrieve the metadata files from the central repository, then it would be possible to upload a working remote repository to my build machine.

• What is the best software to write and organize written copy / content for a website?

  - by johnqtaxpayer

  I'm a newbie product manager, looking for tips on how to write and organize text copy for my company's website. I need to be able to prepare the content for our public site and turn it over to the web designer who publishes it to our live site. I want our UI team to be able to quickly glance at the copy I write and immediately know where on the page I intend for it to go. Currently, I'm using microsoft word to write and color code different text to signify where I want specific text to go. It is difficult for the UI guy to immediately know if something goes into the nav bar or into a header or a description below a header. In addition to that, it would be helpful for me to be able to write the copy in such a way that the web designer could copy and paste it into the XHTML without having to go back and manually replace special punctuation characters with the XHTML entities. What software is out there that will allow a comprehensive solution to these web copywriting issues?

• Getting differences between collections in LINQ

  - by dotnetdev

  Hi, I have a collection of image paths, and a larger collection of Image objects (Which contain a path property). I have the code to check for any matching images, but if there are supposed to be four matching image paths (as that is how many are in the first collection), and there is less than this, how can I get the missing one without writing loops? List<string> ImagesToCheck = new List<string>() { "", "s", "ssdd" }; IEnumerable<HtmlImage> Images = manager.ActiveBrowser.Find.AllControls<HtmlImage>(); var v = from i in Images where ImagesToCheck.Any(x => x == i.Src) select i; if (v.Count() < 3) { } So I need to get the items which are not in the collection titled v, but are in ImagesToCheck. How could I do this with LINQ? Thanks

• Httpd Process High memory usage and slow page loads

  - by Abs

  Hello all, I am running wampserver on my windows vista machine. I have been doing this for a long time and it has been working great. I have completed loads of projects with this setup. However, today, without me changing anything (no configuration etc) only PHP code changes, I find that every time I load pages of my site (those with user sessions or access the database) are really slow to load - Over 30 seconds, they use to take 1 or 2 seconds. When I have a look at the task manager, I can see on page loads the httpd process jumps from 10mb to 30mb, 90mb, 120mb, 250mb and then back down again. I have tested previous php code projects and they seem to all be slow as well! What is going on? Thanks all for any help on this confusion issue!

• Simulating python's With statement in java

  Is there something like Python with context manager in Java? For example say I want to do something like the following: getItem(itemID){ Connection c = C.getConnection(); c.open(); try{ Item i = c.query(itemID); }catch(ALLBunchOfErrors){ c.close(); } c.close(); return c; } where in python I just have: with( C.getConnection().open() as c): Item i = c.query(itemID); return i;

• Reading programming tutorials while at work

  - by Teifion

  I work in a call centre and have been told by my manager that when there are no calls coming through they're happy for me to read stuff on the internet. There is a net filter in place but I can access SO from work which is always handy. I'm searching for articles that will make me a generally better programmer. I code in Python but combine it with Postgres and JS quite a lot if that helps. I'm currently reading Dive into python3 but I fear it won't last me much longer and would really like to expand my programming ability.

• Icon fonts vs images

  - by Miss A

  My manager tells me not to use icon fonts on our websites, as it is another http request plus the extra kBs to download. Also because I would have to use content before for the font (I can't change the html), he prefers background images so it works in IE7. Personally I love the little things, so nice and crisp and resizeable! I get it if we only use a couple of icons on a website but if I would use, say 5 icons on a site - what do you guys think? Is it worth using an icon font or is he right thinking that it is not? I am just a sucker for anything new and exciting, and this year it is the retina display.

• How Many HABTM relationships in cakephp is too many?

  - by user559540

  Hi all, I'm struggling with deciding how many HABTM relationships I really need in my cakephp app. I guess I don't quite get what "has" truly means. I don't want to have more HABTM tables than necessary. Here's what I have in my database: Users Properties Leases Payments Repairs user HABTM properties, user HABTM leases, user HABTM users, user HABTM repairs, property hasMany repairs, property hasMany leases, lease hasMany repairs. Also, I have two aliases for my users model (manager and tenant). This is one of the reasons I ended up with so many HABTM relationships, but I'm not sure it's necessary. Do I have too many user HABTM relationships? Would it be better to just have cake recurse through my models? Thanks!

• Fastmm4 and leaking handles...

  - by JD

  Hi to all, I have just used FastMM4 to detect leaks. I did not realise our application was using a DLL which was leaking event handles and so I fixed any leaks reported by FastMM4 but not the handles as it was not reported. My questions are, would have FastMM4 have reported the leaking event handles? Would this require me to rebuild the dlls with FastMM4 included? I also heard someone mention ShareMM, do I need to add that? I am using Delphi2007, which I think is using the borland memory manager and if so, should I replace it with the fastMM4 one? What are the steps to do that? Sorry for asking so many questions, I am looking at delphi after a few years of doing .net development. JD.

• How does LocationManager work

  - by user2511882

  I have been going through the google docs for the locationManager API and specifically over the method locationManager.requestLocationUpdates(LocationManager.NETWORK_PROVIDER, 60000, 10, this); In the above line, the manager will check for location updates after each minute and distance of 10 meters. My question is does it actually take both the parameters into consideration? For example if you are driving along how will the method work? Will it start looking for updated locations since you are over the minimum distance between the two updates or will it wait for a minute irrespective? If someone can tell me its behavior, it would be great. Thanks.!!

• Should a service layer return view models for an MVC application?

  - by erg39

  Say you have an ASP.NET MVC project and are using a service layer, such as in this contact manager tutorial on the asp.net site: http://www.asp.net/mvc/tutorials/iteration-4-make-the-application-loosely-coupled-cs If you have viewmodels for your views, is the service layer the appropriate place to provide each viewmodel? For instance, in the service layer code sample there is a method public IEnumerable<Contact> ListContacts() { return _repository.ListContacts(); } If instead you wanted a IEnumerable, should it go in the service layer, or is there somewhere else that is the "correct" place? Perhaps more appropriately, if you have a separate viewmodel for each view associated with ContactController, should ContactManagerService have a separate method to return each viewmodel? If the service layer is not the proper place, where should viewmodel objects be initialized for use by the controller?

• jquery for each function

  - by jonathan p

  I have added a show more or less function to a div - this all works fine however now i need to only allow this functionality if a element is over a certain height in this case. there are numerous classes of the same so i need to do the check on each element. although i am having problems getting it to work see code below : $(document).ready(function() { $(".less").hide(); $(".more").each(function() { var actualHeight = ($(this).parent().parent().find('.appsList').height()); if (actualHeight < 150) { $(".more").hide(); } }); $(".more").click(function() { var paragraphHeight = ($(this).parent().parent().find('.appsList').height()); if (paragraphHeight > 150) { $(this).parent().parent().find('.appsHolderBody').animate({height:(paragraphHeight + 100) }); $(this).hide('slow'); $(this).parent().find('.less').show(); } return false; }); $(".less").click(function() { $(this).parent().parent().find('.appsHolderBody').animate({height:190 }); $(this).hide('slow'); $(this).parent().find('.more').show(); return false; }); }); Any help would be greatly appreciated - please note when i am targeting the parent using .parent.parent i know its not pretty but could'nt get it to run using eq(4) for some reason. so the main problem is with this part of code $(".more").each(function() { var actualHeight = ($(this).parent().parent().find('.appsList').height()); if (actualHeight < 150) { $(".more").hide(); } it hides all of the elements $(".more") instead of the ones that match the condition. html as requested <div class="appsHolder"> <div class="appsHolderBody"> <h5 class="appTitle">General Apps</h5> <ul class="appsList"> <li class="mainAppList">Resource Manager</li> <li><a href="">Launch</a> <a href="">Info</a></li> <li class="mainAppList">Resource Manager</li> <li><a href="">Launch</a> <a href="">Info</a></li> <li class="mainAppList">Yet Another App</li> <li><a href="">Launch</a> <a href="">Info</a></li> <li class="mainAppList">Yet Another App</li> <li><a href="">Launch</a> <a href="">Info</a></li> <li class="mainAppList">Yet Another App</li> <li><a href="">Launch</a> <a href="">Info</a></li> <li class="mainAppList">Yet Another App</li> <li><a href="">Launch</a> <a href="">Info</a></li> <li class="mainAppList">Yet Another App</li> <li><a href="">Launch</a> <a href="">Info</a></li> <li class="mainAppList">Yet Another App</li> <li><a href="">Launch</a> <a href="">Info</a></li> </ul> </div> <div class="appsHolderExpander"> <a href="" class="more">More <img src="/wps/PA_applicationsintros/./img/downArrow.png" /></a> <a href="" class="less">Less <img src="/wps/PA_applicationsintros/./img/upArrow.png" /></a> </div> </div> <div class="appsHolderAdvertising"> <div class="appsHolderBody"> <h5 class="appTitle">Advertising Apps</h5> <ul class="appsList"> <li class="mainAppList">ATEX</li> <li><a href="">Launch</a> <a href="">Info</a></li> </ul> </div> <div class="appsHolderExpander"> <a href="" class="more">More <img src="/wps/PA_applicationsintros/./img/downArrow.png" /></a> <a href="" class="less">Less <img src="/wps/PA_applicationsintros/./img/upArrow.png" /></a> </div> </div> cheers in advance

• Android - BaseGameUtil Complicated Import

  - by Fabiow Quixadá

  I've seen many topics in stackoverflow, such as Cannot import BaseGameUtils (Eclipse weirdness) and Android: cannot import BaseGameUtils successfully in Eclipse but none resolved my problem. I've followed https://developer.android.com/google/play-services/setup.html#Setup - the Add Google Play Services to Your Project [Using Eclipse with ADT], I THINK my project correctly references the google play services lib since up to that point nothing wrong happened. Then, following https://developers.google.com/games/services/android/quickstart, I've downloaded BaseGameUtils but when I import the two projects [TypeANumber & BaseGameUtil], they came named as main and MainActivity. I've renamed BaseGameUtil as so and have marked it as lib and imported it to my project through Properties Android Library, but I can't extend extend a class from BaseGameUtil because it's not even suggested. Also, I have not installed Android L and Android 4.4W from SDK Manager in Eclipse, altough I think that's no the case. Can anyone please help in this? Thanks so much in advance
