  • Hidden features of Qt.

    - by Lukasz Lew
    A little is hidden in Qt given splendid documentation. But given vastness of Qt functionality paradoxically many useful features have been overlooked by me (and reimplemented or work-arounded). What Qt functions you wish you have noticed earlier?

  • Android: DOM-Model to XML

    - by poeschlorn
    Hey Guys, analogue to this one (http://stackoverflow.com/questions/2788345/replacing-xml-in-file-from-document-in-java or http://www.exampledepot.com/egs/javax.xml.transform/WriteDom.html) I try to use it under Android... The problem is, that I can't use the suggested solution under android, because it throws java.lang.verifyError... After reading a little bit, I found out, that the class that was used to store the data to file, is not usable in android... can you suggest another solution, which is similar easy to use?

  • How do I force a jQuery click event to proceed any control click event on ASP.Net page

    - by Cen
    I've found posts about making a click event with jQuery for a button, however I need a little more then that. When any postback occurs on a page, I need to fire off a jQuery click event. Based on a condition, I want to continue processing (including running the server-side event code after the jQuery code), or, perform a redirect. I'm not quite sure how to go about this. Your help is appreciated!

  • Does anyone here uses PHP-GTK? Is there a better alternative?

    - by levhita
    I had made some questions regarding php-gtk(there are only 4 php-gtk tagged questions and 3 are mine) and I end up answering myself because no one answer them. I know is a strange language selection but I was attracted to it because it runs on several OS's and the fact that I can reuse some of my code (also the apps end up looking good and I can make little installers in NSIS that just rocks). Is there a better alternative, that is free(as freedom) and can run on several platforms?

  • SVN Tree Conflict Errors

    - by John
    I seem to see such errors quite often in our SVN 1.6 repo. We got these quite a lot while we used to just work on /trunk so I don't think it's due to merge/branching confusion. It seems that a cleup and marking the conflict resolved always works, but it's a little concerning to see errors in your version control system when you're just adding/updating/deleting files. What causes it?

  • Getting Tomcat user in Java

    - by wolfi
    Hey everybody, is there a way to get the logged in user name (and group) from a Tomcat system. I read something about configuring Tomcat, so it is getting the user information out of a database. But I found now information about getting the name of the user (in my GWT Project), which is logged in. I'm trying to write a little GWT project and would like to publish the user name to the front page. Thx for your help.

  • Web based printing from a Django application?

    - by lud0h
    Is there any recent developments in web based printing? I know using @media print in CSS, PDF based solution or iTextSharp but they are not really easy (except @media print) but alignment is little tricky if receipt contains barcodes or if I have to format for A5 etc., Is there anything new in HTML5 which will support this? I would like to print receipts from a Django based webapplication. Any tips? Thanks.

  • Choosing the right template engine

    - by asrijaal
    Hi there, since today - I always used simple JSP Tags and JSTL which works but now I'm looking for a little bit more features and maybe more usability. With googling I've found Freemaker, Velocity and Tiles which seem to be very famous. Does someone of you has some further experiences with some of these and can give me a short brief about it. Or are there other frameworks which are worth to look into?

  • The order of a SQL Select statement without Order By clause

    - by Yousui
    As I know, from the relational database theory, a select statement without an order by clause should be considered has not particular order. But actually in SQL Server and Oracle (I've tested on those 2 platforms), if I query from a table without an order by clause multiple times, I always get the results in the same order. Does this behavior can be relied on? Anyone can help to explain a little? Thanks!

    - by David
    Does anyone know of a good book on the Castle Project? I'm interested in learning more about any of the Castle projects (ActiveRecord, MonoRail, Windsor, anything!) and searches for Castle on Amazon are a little frustrating with the need to weed out all the fiction and nonsense.

  • Compile/use unrar C++ source for iphone app?

    - by greypoint
    Writing an app that will include the ability to decompress zip and rar files. I think I'm OK on how to handle the .zips but .rars seem a little more trouble. I noticed that rarlabs has source available but it's C++. Is there a way to compile, wrap or otherwise use this code within an iPhone app? Reference: http://www.rarlab.com/rar_add.htm Open to alternate suggestions on how to handle .rar files as well. I'm still pretty much a newbie so please explain in small words :)

  • How stable are Cisco IOS OIDs for querying data with SNMP across different model devices?

    - by Daniel Papasian
    I'm querying a bunch of information from cisco switches using SNMP. For instance, I'm pulling information on neighbors detected using CDP by doing an snmpwalk on .1.3.6.1.4.1.9.9.23 Can I use this OID across different cisco models? What pitfalls should I be aware of? To me, I'm a little uneasy about using numeric OIDs - it seems like I should be using a MIB database or something and using the named OIDs, in order to gain cross-device compatibility, but perhaps I'm just imagining the need for that.

  • When to use a namespace or a struct?

    - by Justen
    I was just reading a little bit on them from http://www.cplusplus.com/doc/tutorial/namespaces/ and it seems like a struct is capable of the same things? Or even a class for that matter. Maybe someone here can better define what a namespace is, and how it differs from a struct/class?

  • jQuery slider vanishes after container div is toggled

    - by Shahar Evron
    I have a page which contains a jQuery-UI horizontal slider, created using a little function, inside a DIV which can be displayed / hidden by clicking on it's title, using $.toggle(). Problem is, once the div is hidden, when it is expanded the slider is gone. A simplified demo of the problem can be seen here: http://arr.gr/jquery-issue.html (file contains all relevant source code) - when clicking the "Advanced Options" title to hide and then show the div, the slider is no longer there. Any suggestions on how to work around this?

  • Django admin fails when using includes in urlpatterns

    - by zenWeasel
    I am trying to refactor out my application a little bit to keep it from getting too unwieldily. So I started to move some of the urlpatterns out to sub files as the documentation proposes. Besides that fact that it just doesn't seem to be working (the items are not being rerouted) but when I go to the admin, it says that 'urlpatterns has not been defined'. The urls.py I have at the root of my application is: if settings.ENABLE_SSL: urlpatterns = patterns('', (r'^checkout/orderform/onepage/(\w*)/$','checkout.views.one_page_orderform',{'SSL':True},'commerce.checkout.views.single_product_orderform'), ) else: urlpatterns = patterns('', (r'^checkout/orderform/onepage/(\w*)/$','commerce.checkout.views.single_product_orderform'), ) urlpatterns+= patterns('', (r'^$', 'alchemysites.views.route_to_home'), (r'^%s/' % settings.DAJAXICE_MEDIA_PREFIX, include('dajaxice.urls')), (r'^/checkout/', include('commerce.urls')), (r'^/offers',include('commerce.urls')), (r'^/order/',include('commerce.urls')), (r'^admin/', include(admin.site.urls)), (r'^accounts/login/$', login), (r'^accounts/logout/$', logout), (r'^(?P<path>.*)/$','alchemysites.views.get_path'), (r'^static/(?P<path>.*)$', 'django.views.static.serve', {'document_root':settings.MEDIA_ROOT}), The urls I have moved out so far are the checkout/offers/order which are all subapps of 'commerce' where the urls.py for the apps are so to be clear. /urls.py in questions (included here) /commerce/urls.py where the urls.py I want to include is: order_info = { 'queryset': Order.objects.all(), } urlpatterns+= patterns('', (r'^offers/$','offers.views.start_offers'), (r'^offers/([a-zA-Z0-9-]*)/order/(\d*)/add/([a-zA-Z0-9-]*)/(\w*)/next/([a-zA-Z0-9-)/$','offers.views.show_offer'), (r'^reports/orders/$', list_detail.object_list,order_info), ) and the applications offers lies under commerce. And so the additional problem is that admin will not work at all, so I'm thinking because I killed it somewhere with my includes. Things I have checked for: Is the urlpatterns variable accidentally getting reset somewhere (i.e. urlpatterns = patterns, instead of urlpatterns+= patterns) Are the patterns in commerce.urls valid (yes, when moved back to root they work). So from there I am stumped. I can move everything back into the root, but was trying to get a little decoupled, not just for theoretical reason but for some short terms ones. Lastly if I enter www.domainname/checkout/orderform/onepage/xxxjsd I get the correct page. However, entering www.domainname/checkout/ gets handled by the alchemysites.views.get_path. If not the answer (because this is pretty darn specific), then is there a good way for troubleshoot urls.py? It seems to just be trial and error. Seems there should be some sort of parser that will tell you what your urlpatterns will do.

  • Remove the complete stying of a html button/submit

    - by Saif Bechan
    Is there a way of completely removing the styling of a button in Internet Explorer. I use a css sprite for my button, and everything looks ok. But when i click the button, it moves to the top a little, it makes it look out of shape. Is there a css click state, or mousedown? I don't know what triggers that state. I know it't not a really big deal, but sometimes it's the small things that matter.
