• writing to a file in nasm using system calls

  - by yurib

  As part of an assignment I'm supposed to write to a file using system calls. Everything works fine except when I try to open the file in gedit (linux), it says it can't identify the character encoding. Notepad (on windows) opens the file just fine. Why doesn't it work on linux ? here's the code: section .text global _start _start: mov EAX, 8 mov EBX, filename mov ECX, 0700 int 0x80 mov EBX, EAX mov EAX, 4 mov ECX, text mov EDX, textlen int 0x80 mov EAX, 6 int 0x80 mov eax, 1 int 0x80 section .data filename db "./output.txt", 0 text db "hello world", 0 textlen equ $ - text thanks :)

• Learning Objective-C 2.0 and ASP.NET 4.0 simultaneously?

  - by Sahat

  (HOBBY) I own a Macbook Pro and iPod Touch so developing iPhone/iPod/iPad apps seems like a logical thing to do in order to get some experience in the programming field. Besides I want to write a new application similar to the Capsuleer (Character skills monitor app for EVE Online MMO) but with more features. It's something I'd love to have on my own iPod Touch and I am sure other people will welcome a new EVE Online app for their iPhone or iPod Touch. (CAREER) I want to learn ASP.NET (and possibly Silverlight later on) for my potential future job. I plan to work in the .NET field, so it's a good idea for me to start learning C# and ASP.NET ASAP. Is it a good idea to learn completely unrelated technologies at the same time? Or would it be better to learn one thing at a time? Objective-C first, and ASP.NET second. Or vice versa. Thanks, Sahat

• Keep TabItems in a TabControl from repositioning?

  - by Kirn

  Hi everyone, In WPF, Is there a simple way to stop TabItems in a TabControl from being repositioned when the selected TabItem changes? So that clicking on a TabItem would simply display its contents, but not reposition the TabItems as it usually does (by moving the selected TabItem to the bottom row of tabs if it wasn't there already). Edit: To clarify, I do want the tabs to be displayed in multiple rows, I just don't want the tab headers to be repositioned when a TabItem from a row other than the bottom row is selected. I'd like the collection of headers to remain completely static, but for the contents of that TabItem to still be displayed when its header is clicked. Thanks!

• Diamonds with question marks

  - by hokkaido

  Hi, I'm getting these little diamonds with question marks in them in my HTML attributes when I present data from my database. I'm using EPiServer and a few custom properties. This is the information I've gathered, I save my data as a XML document, since I use custom EPiServer properties which need more than one defined value. This is saved as UTF8. It's only attributes in element tags which have this problem, such as align=left becomes align=?left?. There is no " character there, but I get the diamonds anyway. If I use " outside an element, it works and shows correctly. Any clues?

• Adjust Title Helper in Ruby on Rails Tutorial 3.2 to deal with & properly

  - by memoht

  I am using the title helper from the 3.2 edition of the Ruby on Rails Tutorial by Michael Hartl and just realized a snag with the & character showing up in the title as &Amp instead. The relevant snippet of code is here Official Sample App 2nd Edition The problem. I have a School model and am using the School name on the Show view as follows: <% provide(:title, @school.name) %> If my School has a & in the name, it is being replaced with &Amp in the browser title. Ryan Bates Railscasts site has a similiar title helper that solves this issue this way but it is using content_for instead of provide. Trying to adjust the Rails Tutorial helper, but having trouble getting it work properly. Works great expect for this issue.

• Set Caret position with JTextArea in JScrollPane

  - by Albinoswordfish

  Right now I have a JTextArea inside of a JScrollPane. For the current content it has both a vertical and horizontal scroll bar showing up. I'm trying to implement a search functionality where a user can search for a certain string and it will set the caret position to the first occurrence of that string. However it seems that JScrollPane only scrolls vertically when I set my caret position. So matching strings going off the JTextArea horizontally will completely get missed and the horizontal scroll bar won't scroll at all. I'm using the basic function setCaretPosition() for the JTextArea Does anybody have any idea why my JScrollPane isn't moving horizontally using setCaretPosition() Edit: It appears the horizontal scroll bar is scrolling but it moves so little that it's barely noticeable. I can only see the very first pixel of the character. Is there a way to have the scrollbar center (or as much as possible) to the caret position?

• c++ builder TClientWinSocket simbol substitution

  - by Vlad

  I have the following problem. I have to send a text telegram over tcp/ip to a host device. Telegram should be terminated using 0x1A (CTRL-Z) character. But when I send it, host told me that there is a wrong symbol in the telegram. When I terminate a telegram with 32 (0x20) everything is ok. I look the transfered data using WireShark and I see that when I send 0x1A it is substituted with 0x16, when I send 32 (0x20) as a terminator it is somehow substituted with 0x1A. Can you explain it please. P.S. I am working on windows 7, using c++builder xe2. Thanks, Vladimir

• backslashes in url variables

  - by namtax

  Hi there I have set up my coldfusion application to have dynamic urls on the page, such as www.musicExplained/index.cfm/artist/:VariableName However my variable names will sometimes contain backslashes, such as www.musicExplained/index.cfm/artist/GZA/Genius This is causing a problem, because my application presumes that the slash in the variable name represents a different section of the website, the artists albums. So the URL will fail. I am wondering if there is anyway to prevent this from happening? Do I need to use a function that replaces slashes in the variable names with another character? Thanks

• Determining a Flex event's default behavior

  - by Jeremy Mitchell

  How can I tell what the default behavior for a cancelable event is? For example, I read somewhere that the TextEvent.TEXT_INPUT has a default behavior and that default behavior includes adding a text character associated with the key that was pressed to a TextInput. That makes perfect sense. But if I hadn't read that, how would I know what the default behavior is? Other than guessing. In this case, it's probably obvious. But in other situations, it might not be. For example, in the docs, look at DataGridEvent.HEADER_RELEASE's cancelable property. It says: cancelable: true so, there appears to be a "default behavior" associated with a DataGridEvent.HEADER_RELEASE event. But what is it? And why would I cancel it if I'm not really sure what it is? :) thanks.

• Time complexity O() of isPalindrome()

  - by Aran

  I have this method, isPalindrome(), and I am trying to find the time complexity of it, and also rewrite the code more efficiently. boolean isPalindrome(String s) { boolean bP = true; for(int i=0; i<s.length(); i++) { if(s.charAt(i) != s.charAt(s.length()-i-1)) { bP = false; } } return bP; } Now I know this code checks the string's characters to see whether it is the same as the one before it and if it is then it doesn't change bP. And I think I know that the operations are s.length(), s.charAt(i) and s.charAt(s.length()-i-!)). Making the time-complexity O(N + 3), I think? This correct, if not what is it and how is that figured out. Also to make this more efficient, would it be good to store the character in temporary strings?

• Regular expression: who's greedier?

  - by polygenelubricants

  My primary concern is with the Java flavor, but I'd also appreciate information regarding others. Let's say you have a subpattern like this: (.*)(.*) Not very useful as is, but let's say these two capture groups (say, \1 and \2) are part of a bigger pattern that matches with backreferences to these groups, etc. So both are greedy, in that they try to capture as much as possible, only taking less when they have to. My question is: who's greedier? Does \1 get first priority, giving \2 its share only if it has to? What about: (.*)(.*)(.*) Let's assume that \1 does get first priority. Let's say it got too greedy, and then spit out a character. Who gets it first? Is it always \2 or can it be \3? Let's assume it's \2 that gets \1's rejection. If this still doesn't work, who spits out now? Does \2 spit to \3, or does \1 spit out another to \2 first?

• NavigationController does not set view properties correctly when pushed

  - by Sheehan Alam

  I have a UITabBarControllerDelegate that pushes a new view controller when a certain tab is pressed: - (void)tabBarController:(UITabBarController *)tabBarController didSelectViewController:(UIViewController *)viewController { MyView* myView = [[[MyView alloc] initWithNibName:@"MyView" bundle:nil]autorelease]; if([self.tabBarController.selectedViewController.title isEqualToString:@"Friends"]){ NSLog(@"Clicked Friends"); myView.reloadFriends = TRUE; [self.navigationController myView animated:YES]; } } However, if I change my code to set the tabbar's selected view controller to myView everything works, but I don't get my navigation bar: if([self.tabBarController.selectedViewController.title isEqualToString:@"Friends"]){ NSLog(@"Clicked Friends"); myView.reloadFriends = TRUE; self.tabBarController.selectedViewController = myView; } How can I set the reloadFriends property in MyView and have the navigation bar at the top?

• Valid HTTP header? `GET /page.html Http1.0`?

  - by Earlz

  Ok so I've been reading up on HTTP and found this page. This is an example HTTP request that was posted there: GET /http.html Http1.1 Host: www.http.header.free.fr Accept: image/gif, image/x-xbitmap, image/jpeg, image/pjpeg, Accept-Language: Fr Accept-Encoding: gzip, deflate User-Agent: Mozilla/4.0 (compatible; MSIE 5.5; Windows NT 4.0) Connection: Keep-Alive I tried it in telnet and it worked. But everywhere else I see this kind of request line GET /http.html HTTP/1.1 The important different is that HTTP is all caps and the / character. Are they both correct? They both seem to work on the sites I've tested it on. I've skimmed the RFC of HTTP but didn't find anything of use. Has anyone else seen this kind of request header? Is it officially supported?

• jQuery UI Tabs causes content to be cutoff on page load in IE6/IE7

  - by Patricker

  I have a web page with jQuery UI Tabs on it. Some of the content is in an html table. When the page loads some of the content will be cut off at the end, usually just the last few letters. If I change tabs and come back to the original tab then it fixes itself. This appears to be an issue just with Internet Explorer, specifically IE6/7, I haven't tested it on 8. I believe the issue is directly related to my use of the Blueprint CSS Framework as if I don't use Blueprint then I don't have the issue. Has anyone encountered this before or have any ideas?

• How to use backreferences in PHP

  - by Slinky

  I want to add a character to the end of each file extension found in a body of text using preg_replace(). Here is some sample text: $string='http://www.mysite.com/expert/images/imageone.jpghttp://www.mysite.com/expert/images/imagetwo.jpg'; This search & replace works fine in TextWrangler, appending a semi colon to file extensions: (\.(jpg|gif|html?|php|tiff?|pdf|png)) \1; Translated to PHP, however does not work, having no effect; no errors. preg_replace("/(\.(jpg|gif|html|php|tif|tiff|pdf|htm|png))/","\\1;",$string);

• Remote XML retrieval

  - by rrrfusco

  I'm retrieving a remote XML file with wget -O remotefile localfile with a cron tab. Every so often the local file becomes malformed probably because of double whitespace (according to firefox) between the CDATA tags. Sometimes the parser gives an error for ' > ' missing, but upon checking the xml file the ' > ' exists... The remote xml file never gives malformed errors when called in the url. EDIT It seems CDATA is not parsed by the xml parser. (w3schools) Is there a way to set wget to retain wellformed XML? If not wget, What is a good way to continously retrieve a remote XML file and keep it well formed?

• How can I update many rows with SQL in a single table?

  - by tmarouda

  Hi folks. I have a table and one of the columns holds web addresses like: 'http://...' or 'https://...'. The problem is that there are some invalid entries, like 'shttp://...' or '#http//...'

I use the following SQL statement: 'SELECT [...] FROM MyTable WHERE WebAddress LIKE '_http%' and I successfuly get the problematic rows. But how am I going to change/correct all of them using an UPDATE statement? If you have some other solution please share it!

• Base64 Encoded Data - DB or Filesystem

  - by Marty

  I have a new program that will be generating a lot of Base64 encoded audio and image data. This data will be served via HTTP in the form of XML and the Base64 data will be inline. These files will most likely break 20MB and higher. Would it be more efficient to serve these files directly from the filesystem or would it be feasible to store the data in a MySQL database? Caching will be set up but overall unnecessary because it is likely that this data will be purged shortly after it is created and served. i know that storing binary data in the DB is frowned upon in most circumstances but since this will all be character data I want to see what the consensus is. As of now, I am leaning toward storing them in the filesystem for efficiency reasons but if it is feasible to store them in a database it would be much easier to manage the data.

• MS SQL Server Text Datatype Maxlength = 65,535?

  - by craigmj

  Software I'm working with uses a text field to store XML. From my searches online, the text datatype is supposed to hold 2^31 - 1 characters. Currently SQL Server is truncating the XML at 65,535 characters every time. I know this is caused by sqlserver, because if I add a 65,536th character to the field directly in Management Studio, it states that it will not update because characters will be truncated. Is the Maxlength really 65,535 or could this be because the database was designed in an earlier version of MS SQL Server (2000) and it's using the legacy text datatype instead of 2005's? If this is the case, will Altering the datatype to Text in sql server 2005 fix this issue?

• Regular Expression .net flavor

  - by user1440109

  Dont ask how this works but currently it does ("^\|(.?)\|*$")....kinda. This removes all extra pipes...part one....I have searched all over no anwser yet. I am using VB2011 beta...asp web form......vb coding though! I want to capture special character pipe (|) which is used to seperate words...i.e. car|truck|van|cycle problem is users lead with, trail with, use multiple, and use spaces before and after...i.e. |||car||truck | van || cycle. another example: george bush|micheal jordon|bill gates|steve jobs <-- this would be correct but when I do remove space it takes correct space out. so I want to get rid of whitespace leading, trailing, any space before | and space after | and only allow one pipe (|)....in between alphanumeric of course.

• Font for mac osx that is as readable and compact as the default xterm (X11) font.

  - by dreeves

  The font used in xterms is extremely compact yet readable. What font is that? The closest I've found that I can use in other other applications is DejaVu Sans Mono or Bitstream Vera Sans Mono. Those are as compact as xterms vertically but take up more space horizontally. I'd really like to switch from xterms to Terminal.app and this is the one thing holding me back. (I also think that font would be much better for emacs, xcode, or whatever editor.) ADDED: In Terminal.app you can adjust the character and line spacing for any font. Is this possible in other applications? I'm open to any other font that is as compact and readable as the xterm font. Dina looks really nice but it doesn't seem to work for Mac.

• How can I retrieve the value of a PASTE (copy-pasta) event in a GWT TextBox?

  - by dominicbri7

  Hello fellow SO members, I want to prevent the user from copy-pasting values in my TextBox IF AND ONLY IF the values do not respect a certain condition. For instance, I created a DigitsOnlyTextBox which will be used for phone numbers. I already made it so only Character.isDigit characters can be typed into the box, and the user cannot copy-paste values into it, using : this.sinkEvents(Event.ONPASTE); and public void onBrowserEvent(Event event) { super.onBrowserEvent(event); // Permet d'empêcher le copier-coller, donc d'entrer des caractères non-numériques if (event.getTypeInt() == Event.ONPASTE) { event.stopPropagation(); event.preventDefault(); } } But I'd like to verify if the copy-pasted String is "digits only" and if so, let the event happen (therefore the text added). tl;dr : see title Thank you for your time. Sincerely.
