• Customizing TabWidget in SDK 1.5, API 3

  - by Dylan McClung

  I'm aware that API 3 doesn't allow a view to be set for a tab, but I still need to modify the TextView displayed as the indicator. I'd also like to change the Drawable for the tab, but I don't see a way to do it without a custom tab view as allowed in 1.6, API 4. Working with this generic example below, is there way to retrieve the TextView and modify its properties or change the drawable? TabHost tabHost = getTabHost(); TabHost.TabSpec spec; spec = tabHost.newTabSpec("nearby") .setIndicator("Nearby Activity") .setContent(R.id.nearby_list); tabHost.addTab(spec); spec = tabHost.newTabSpec("friends") .setIndicator("Friends & Favorites") .setContent(R.id.friends_list); tabHost.addTab(spec); tabHost.setCurrentTabByTag("nearby"); Thanks for any help.

• iPhone simulator app crashes when appending a string

  - by Franklyn Weber

  Hi, I'm a complete novice, so I'm probably missing something really easy, but I can't get my string appending to work. I add the 3rd character to typedDigit & it crashes - the method is called fine and typedDigit will get to 2 characters long. I think everything is declared properly in the header file. Code is - -(IBAction)digitPressed:(UIButton *)sender { NSString *digit = [[sender titleLabel] text]; // in this case, "0" - "9" if (userIsInMiddleOfTyping) { // typedDigit is already at least 1 character long typedDigit = [typedDigit stringByAppendingString:digit]; } else { // first character of typedDigit typedDigit = digit; userIsInMiddleOfTyping = YES; } } Many thanks for any help!

• Regular Expression - Password Validation is not working

  - by Kesavan

  Hi, I have to validate the password using regex. The password rule is like at least 1 uppercase and at least 2 numeric. It works fine except if the character comes at the end of the string. The regular expression which i am using is "^(?=.*\d.{2})(?=.*[A-Z].{1})(?=.*[@#$%^&+=].{2}).{8,12}$" Rules: minimum length = 8 minimum uppercase = 1 minimum numeric = 2 minimum special character = 1 It works for Test123$$, Test$123, TEST123$s, Test123$1, Test12$3 but it fails if the character specified comes at the end of the string like Test123$, Test$a12, Test12aa@, 123aa@@T. Please let me know if there is any fix for this.

• ASP.NET MVC - how to modify requested URLs?

  - by Marek

  The baidu spider seems to be adding ¤ to end of some crawled urls (it seems that it happens with urls containing single unicode character as the last character) The baidu-requested url looks like this: site.com/abc/ä¤ while site.com/abc/ä is the valid url and as linked from many places on my site. The internal problem is that a different route is matched for this kind of url and an unhandled exception occurs. I would not like to lose baidu because of too many 500 errors on the site. I would like to change the requested URL to a different URL by removing the added character before any ASP.NET MVC processing of the request starts. Can I write a request filter/http module or something similar in ASP.NET MVC to remove the trailing '¤' from the urls? I would not like to alter my routes to counter-hack this behavior.

• Large static arrays are slowing down class load, need a better/faster lookup method

  - by Visualize

  I have a class with a couple static arrays: an int[] with 17,720 elements a string[] with 17,720 elements I noticed when I first access this class it takes almost 2 seconds to initialize, which causes a pause in the GUI that's accessing it. Specifically, it's a lookup for Unicode character names. The first array is an index into the second array. static readonly int[] NAME_INDEX = { 0x0000, 0x0001, 0x0005, 0x002C, 0x003B, ... static readonly string[] NAMES = { "Exclamation Mark", "Digit Three", "Semicolon", "Question Mark", ... The following code is how the arrays are used (given a character code). [Note: This code isn't a performance problem] int nameIndex = Array.BinarySearch<int>(NAME_INDEX, code); if (nameIndex > 0) { return NAMES[nameIndex]; } I guess I'm looking at other options on how to structure the data so that 1) The class is quickly loaded, and 2) I can quickly get the "name" for a given character code. Should I not be storing all these thousands of elements in static arrays?

• UITableView cellForRowAtIndexPath occasionally not called?

  - by Tobster

  I'm developing a graphing application that on the main navigation/tab view displays a UIView that renders a graph using openGL. Beneath that view is a UITableView that displays the list of elements on the graph, and an add button. Occasionally, when the user clicks on another tab, and then returns to the graph view tab, the table view does not get redrawn. I have a [tableView reloadData] method being called in the navigation controllers' (also the table view's delegate and data source) viewDidAppear method. numberOfSectionsInTableView and numberOfRowsInSection get called, but cellForRowAtIndexPath does not despite both latter methods returning positive values. This is an intermittant problem, only happening some of the time, but it's not clear what (if anything) influences this. Does anyone have any ideas?

• Can I access an iframe of the same domain in a separate window?

  - by jozecuervo

  How can I detect the presence of and then call a function on a frame that is already loaded in one tab (my iframed facebook app) from a page being loaded in a new tab (from an ad-served link). It seems most examples focus on parent/child iframe communication. In this case, a link will be served from Google Ad Manager, which only allows _top or _blank to be targeted. I want to pass an id through the ad click into the new page/tab on my domain and then JS call over to the frame my app is in to switch state. Both frames are on my domain but not in the same document or window. Is this possible?

• PyGTK "assertion GTK_IS_WINDOW failed

  - by iAndr0idOs

  I'm trying to build a web browser using PyGTK and PyWebKit However, I'm pretty sure my question only concerns PyGTK I have a custom gtk.Notebook class, with an "add tab" button as the last tab. When I click it, it gives me the error /home/ruiqimao/workspace/PyBrowser/src/browser/__init__.py:161: GtkWarning: IA__gdk_window_get_cursor: assertion `GDK_IS_WINDOW (window)' failed gtk.main() twice. And then, my new tab won't show up. I have no idea what is going on, so here is my whole code If any of you could help me, that would be great! Thanks! [EDIT]: Just found out that the problem lies in the w.show_all() line What could this mean?

• Python Textwrap - forcing 'hard' breaks

  - by Tom Werner

  I am trying to use textwrap to format an import file that is quite particular in how it is formatted. Basically, it is as follows (line length shortened for simplicity): abcdef <- Ok line abcdef ghijk <- Note leading space to indicate wrapped line lm Now, I have got code to work as follows: wrapper = TextWrapper(width=80, subsequent_indent=' ', break_long_words=True, break_on_hyphens=False) for l in lines: wrapline=wrapper.wrap(l) This works nearly perfectly, however, the text wrapping code doesn't do a hard break at the 80 character mark, it tries to be smart and break on a space (at approx 20 chars in). I have got round this by replacing all spaces in the string list with a unique character (#), wrapping them and then removing the character, but surely there must be a cleaner way? N.B Any possible answers need to work on Python 2.4 - sorry!

• Split string into multiple lines

  - by RememberME

  I have a long string of comments that I'd like to split into multiple lines. It's currently displayed as <%= Html.Encode(item.important_notes) %> I've played with using .Substring to split it, but can't figure out how to prevent it from splitting in the middle of a word. Instead of characters 1-100 on line 1 and 101-200 on line 2, I'd like to do something like character 1 through the last space before character 100 on line one. That character through the last space before the next 100 characters on line 2, etc. What is the best way to do this? EDIT: using ASP.NET-MVC

So, my class hierarchy is thus: Character - Enemy - Boss                 \                   - Hero Each Character has a public static char avatar to represent him on an ASCII playing field. How do I set a default value for the avatar of each class inherited from Character? Thank you!

• Java multidimensional array and scanner novice Q

  - by Max

  I'm new to Java and trying to in essence implement a grid with a character, and if the user inputs 'w' 'a' 's' or 'd' the character moves up/down/left/right within the plane. I created a multidimensional array sized 10x10 public static String[][] grid = new String[10][10]; And then just used a for loop to print "*"s in a 10x10 grid, except for grid[a][b] which is equal to character "A" i.e. my thing to be moved around. That seemed to work alright, then I needed to detect the 'wasd' input from the user so I set up a: Scanner in = new Scanner (System.in); while (in.hasNext()) And I had then: String s = in.next(); char ch = s.charAt(0); switch (ch) but I couldn't make this work, and it wasn't because I didn't complete the "switch" statement, I did, I just see it void copying and pasting the entire thing. I'm sure its incredibly easy slight thing I am missing, can you please point it out for me?

• What is a good standard for code width?

  - by BillyONeal

  Hello everyone :) I've heard in several places that it's bad to have code that is too wide onscreen. For example: for (std::vector<EnumServiceInformation>::const_iterator currentService = services.begin(); currentService != services.end(); currentService++) However, I've heard many arguments for 80 character wide limits. I'm assuming this 80 character limit comes from the traditional command prompt, which is typically 80 characters wide. However -- most of us are working on something much better than a typical command prompt, and I feel that using an 80 character limit encourages use of variable names that are far too short and do not describe what the variable is used for. What is a reasonable limit for a new project with no existing coding width standard?

• css override not working?

  - by Karin

  I have three tabs that change styles when clicked. class="active" gives the tab the same background as the tab content, while class="inactive" has another color. My problem is the text on the tabs, something's weird with the CSS. The default state of class="active" looks as it should, while the inactive tabs are underlined even though my CSS says text-decoration: none !important; and the clicked active tab text becomes extra bold (or maybe it's a shadow). Please look at my fiddle: http://jsfiddle.net/m8wQM/170/

• Regular Expression for accurate word-count using JavaScript

  - by Haidon

  I'm trying to put together a regular expression for a JavaScript command that accurately counts the number of words in a textarea. One solution I had found is as follows: document.querySelector("#wordcount").innerHTML = document.querySelector("#editor").value.split(/\b\w+\b/).length -1; But this doesn't count any non-Latin characters (eg: Cyrillic, Hangul, etc); it skips over them completely. Another one I put together: document.querySelector("#wordcount").innerHTML = document.querySelector("#editor").value.split(/\s+/g).length -1; But this doesn't count accurately unless the document ends in a space character. If a space character is appended to the value being counted it counts 1 word even with an empty document. Furthermore, if the document begins with a space character an extraneous word is counted. Is there a regular expression I can put into this command that counts the words accurately, regardless of input method?

• How do I reset the state of a view inside a tabbar?

  - by ABeanSits

  Hello CocoaTouch-Experts! This is a fairly straightforward question though my Googling session gave me nothing. How do I reset the state of a view hierarchy located in a tabbar programmatically? The behavior I want to replicate is when the user tapps on a tab twice. This causes the view located under that tab to return to it's initial state. The tab is "owned" by a UINavigationController and when the user reaches a certain point in the view hierarchy there is a button which I want to connect this behavior to. All my attempts have failed except calling on a method in AppDelegate which kills the view and adds it back to the UITabBarController again. But this does not feel like the right way to go. Thanks in advance. Best regards //Abeansits

• Different animations for Jquery ui tabs

  - by audiopleb

  I'm using jquery ui tabs widget. I've not used a jquery theme as i prefer to do my own css and stuff. I've got it working, but what i'd like is to have a different animation effect for the tab content when a different tab is clicked. What i'd like is for the new tab content to slide in from the left. At the moment i have: $("#tabs").tabs({ fx: {slide: 'slow' } }); }); I know the code above is just slide and not slide left but it doesn't even do a slide! I have downloaded the slide effects as part of my custom ui download. I don't know why it isn't working! Is it some css that i'm lacking?! I don't know!!!

• Are there any Visual Studio add-ins for true 'smart tabs'?

  - by Eye of Hell

  Hello. 'Smart Tabs' concept allows to automatically insert tab character for block indentation and space characters for in-block formatting. It's described here. Unfortunately, Visual Studio's 'smart tabs' option in text editor settings just indents text on enter press. Same name, completely different and near useless thing :). So, maybe someone knows of a visual studio addin that can change how 'tab' key work so it will insert tab characters and space characters according to rules mentioned above? Any hints are welcome. Update: I need it for C++. According to comments, ReSharper can do something like this, but only for Basic and C#.

• .Net using Chr() to parse text

  - by Marcx

  I'm building a simple client-server chat system. The clients send data to the server and the server resends the data to all the other clients. I'm using the TcpListener and Network stream classes to send the data between the client and the server. The fields I need to send are, for example: name, text, timestamp, etc. I separate them using the ASCII character 29. I'm also using ASCII character 30 to mark the end of the streamed data. The data is encoded with UTF8.. Is this a good approach? Will I run into problems? Are there better methods? UPDATE: Probably my question was misunderstood, so I explain it better.. Suppose to have a list of data to send from client to server, and suppose to send all the data in only one stream, how do you send these data? Using a markup Using a character as a delimiter Using a fixed length for every fields
