• C/C++ line number

• why many programmers use integer literal on left handside of equality operator?

  - by nash

  Hi, Many a times in blogs and books, i have seen conditions in if statements like this: if(0 == a.size()){...} or if(-1 == str.indexOf(ch)){...} Is there any performance advantage in using integer literals on left hand side in conditions or is it just a style that some programmers prefer?

• What is the best way to do Bit Field manipulation in Python?

  - by ZebZiggle

  I'm reading some MPEG Transport Stream protocol over UDP and it has some funky bitfields in it (length 13 for example). I'm using the "struct" library to do the broad unpacking, but is there a simple way to say "Grab the next 13 bits" rather than have to hand-tweak the bit manipulation? I'd like something like the way C does bit fields (without having to revert to C). Suggestions?

• What's the best way to implement news system without using wordpress ?

  - by Tristan

  Hello, I'm a little afraid of using Wordpress because of his connotation "all made", plus my website is 100% hand coded, actually, i use the phpBB but it's not what I want cause visitors have to go out of the website to go to the forum to see the news. So how/what can I do to have my own news system management (publish/review/moderate comments).... Are there tools (i mean except WYSIWYG) / PHP class I can use to implement myself ? I hope you understand what i mean. Thank you :)

• Is there a 'RowSpan = "All"' in WPF

  - by Chris Spicer

  Take for the following for example: <GridSplitter Grid.Row="0" Grid.Column="1" Background="Yellow" HorizontalAlignment="Stretch" VerticalAlignment="Stretch" Width="Auto" Height="Auto" Grid.RowSpan="3" ResizeDirection="Columns etc etc This will create a GridSplitter across the 3 rows that I have in my grid. However, it's conceivable that I might add another row to my grid at a later stage, and I don't really want to go back and have all of my rowspans. My first guess was Grid.RowSpan="*", but that doesn't compile. Does anyone know the answer to this off hand?

  - by Nissan Fan

  Take a look at http://www.pmverge.com at the "We're in Bootstrap Mode" DIV on the right-hand side. Having that background tile image is causing the IE browser (all versions) to drag when scrolling. What can I do to keep that tiled style but not have it slow down IE. background-image: url(http://blog.pmverge.com/assets/images/background.gif) NOTES Yes this is the Stackoverflow.com engine as I'm licensing it. The background watermark image is not slowing the page down (though it has about 50k).

• Windows Mobile 7 corporate device...

  - by Toymaker

  Does anyone know of a Windows Mobile 7 device aimed at business use? I’m looking for something with bar code scanning capability. Psion, hand held, and honeywell only offer 6.5 at the moment. Granted, Windows Mobile 7 just barely came out and these sorts of devices usually lag a bit behind consumer toys...but hopefully someone can help.

• What is the NetBeans keyboard shortcut for code generation for child class constructors?

  - by waiwai933

  I was coding in NetBeans (PHP) today, and my hand slipped while I was typing a constructor. It must have hit a keyboard shortcut, because a constructor that was designed for a child class appeared on my screen (i.e. it called the parent constructor, so it's not the Insert Code -> Constructor, I don't think). Does anyone know what the shortcut is?

• Drupal 6 CCK - Having a textbox appear when 'Other' is selected

  - by espais

  I have a special content-type that I have created, and one of the fields is a radio button list. The last element is named 'Other' and I would like to have a textbox appear and allow the user to enter in a non-defined value. Is this sort of capability provided by any sort of module, or is this something that needs to be coded by hand? (If so, would you mind pointing me in the correct direction?)

• OOP design for DMS that allows searching and grouping

  - by James P.

  I'd like to make a searchable Document Management System and allow a user to group documents together. On one hand, there would be a functionality that registers/fingerprints in a linear fashion and, on the other, one that associates documents into groups. How could I compromise between the two in terms of object design?

• Powerbuilder resources

  - by afilatun

  I'm recently working in a company where we use PowerBuilder extensively. The only documentation or resources we have access to is some basic course saying things like "Do A, then B and you'll get C". I was wondering if there is some better crash courses or tutorials for this language on the net or somewhere else which actually explain something instead of simply taking me by the hand.

• What font and size is used in Windows 7 File Explorer Tree

  - by Stefan Koell

  I am having a hard time to find out which font is used by the Win 7 File Explorer in the tree view on the left hand side. Better, of course, would be if I can programmatically find out which the right font is (C#). I searched the Windows 7 design guidelines but this particular scenario is not listed (at least I couldn't find it). So anyone good with fonts?

• Where does that randomness come from ?

  - by Jules Olléon

  I'm working on a data mining research project and use code from a big svn. Apparently one of the methods I use from that svn uses randomness somewhere without asking for a seed, which makes 2 calls to my program return different results. That's annoying for what I want to do, so I'm trying to locate that "uncontrolled" randomness. Since the classes I use depend on many other, that's pretty painful to do by hand. Any idea how I could find where that randomness comes from ?

• Page.Request behaviour

  - by StupidDeveloper

  I have a page and few controls. I'm doing a normal postback. On InitializeCulture event of the page the Page.Request object contains e.g. controls with their values - and that's great. But on the other hand, when I'm trying to access this collection on the Page_Load or OnInit events, it's way smaller and doesn't have any of the controls that have been there before. Can anyone tell me what happens with Page.Request between these events?

• Automatically inserting new fields in a web.config file

  - by MarceloRamires

  I have an ASP.NET project which has already some custom fields in it's web.config file. I've added in it three more fields and used them in my changes, and it's working great. But where it needs to be used, there aren't these thre fields in the web.config (this was expected, I've just added by hand for tests and developing). How do I check the existance of fields in web.config, and in case of not finding it, how do I add it permanently to the web.config ? Thank you

• Find out the number of digits of min/max values of an integral type at compile time

  - by Checkers

  Is there a way to find out the number of digits of min/max values of an integral type at compile time so that it's suitable to be placed as a template parameter? Ideally, there will be an existing solution in, for example, Boost MPL. Failing that I'm looking for some pointers for a hand-coded solution.
