• armv6 / armv7 errors when compiling for iPhone

  - by Chris

  I am having problems trying to compile my App to my iPhone. I upgraded to the new SDK and have 4.0 on my phone... which I did not do that. I am compiling for 3.1.2 - It works fine in the simulator but when I "build" for the Device, it gives me this line of errors: Link /Users/me/Apps/myapp/build/app.build/Debug-iphoneos/app.build/objects-normal/armv7/appname In /Developer/Platforms/iPhoneSimulator.platform/Developer/SDKs/iPhoneSimulator3.1.3.sdk/user/lib/libz.dylib, missing required architecture armv7 in file then the actual failure occurs on: Command /Developer/Platforms/iPhoneOS.platform/Developer/usr/bin/gcc-4.2 failed with exit code 1 Any help would be greatly appreciated

• Can I debug with python debugger when using py.test somehow?

  - by Joel

  I am using py.test for unit testing my python program. I wish to debug my test code with the python debugger the normal way (by which i mean pdb.set_trace() in the code) but I can't make it work. Putting pdb.set_trace() in the code doesn't work (raises IOError: reading from stdin while output is captured). I have also tried running py.test with the option --pdb but that doesn't seem to do the trick if I want to explore what happens before my assertion. It breaks when an assertion fails, and moving on from that line means terminating the program. Does anyone know a way to get debugging, or is debugging and py.test just not meant to be together?

  - by mare

  Given the code below within which I render a bunch of checkboxes in my view and the code for controller, someone please explain how can I get the values of the checkboxes (I need the key and the checked status) in the controller. <% foreach (string mappingId in Model.Mappings) {%> <tr><td> <%=mappingId %><br /> <%=Html.Label("Checkbox_" + mappingId, "Sync?")%> <%=Html.CheckBox("Checkbox_" + mappingId, true) %> </td></tr> <% } %> [HttpPost] public ActionResult Sync(FormCollection collection) { foreach (var posted in collection) { // here the "posted" variable shows up in the debugger as // "Checkbox_AD0D1" as Value (AD0D1 being the key in my model) and of type "object" // of course, this line fails but it shows what I want to do bool currentCheckbox = (bool) posted; } return View(); }

• Django ValueError at /admin/

  Hello, I am running Django with mod_python on a Red Hat Linux box in production. A little while ago, for a reason unknown to me, the admin stopped working, throwing a 500 error.

How can I troubleshoot this problem? Is there anyone who had the same issue? Thanks, mspoerr

• CSS - how can I handle the size difference between serif and sans-serif fonts?

  - by orbit82

  I'm working on a WordPress that will allow the site administrator to switch between sans-serif and serif fonts. I'm trying to code the stylesheet in such a way that the font sizes are similar whether or not they choose Georgia vs Arial. The problem is that when I have it looking nice with a serif font, it looks WAY too big when in sans-serif. When I then adjust it to look nice in a sans-serif font, it looks WAY too small in serif. Is there an ideal font size and line-height that works well with both serif and sans-serif? Or do I need to make separate stylesheets (a serf version and a sans-serif version)? P.S. I've set a base font size on the body at 12px, and then set the rest of the font sizes as a percentage of the base. Of course, this base font size could be set in ems or in percent, because the percentages will still scale proportionally.

• Creating Membership Tables, SPROCs, Views in Attached DB

  - by azamsharp

  I have AdventureWorks database mdf file in my VS 2010 project. Is there anyway I can create Membership tables inside my AdventureWorks database. I know I can detach the database attach in SQL SERVER 2008. Create the tables and then detach. But I don't have SQL SERVER 2008 and I want to see if this can be done using command line tool. I tried this but no use: aspnet_regsql.exe -d AdventureWorks.mdf -A mr -E -S .\SQLEXPRESS Update: If I right click and see the properties of the AdventureWorks.mdf database then it shows the name as "C4BE6C8DA139A060D14925377A7E63D0_64A_10\ADVENTUREWORKSWEBFORMS\ADVENTUREWORKSWEBFORMS\ADVENTUREWORKS\APP_DATA\ADVENTUREWORKS.MDF" This is interesting!

• IE8 won't load JavaScript file in "Compatibility View."

  - by Don Jones

  Here's my JS insert: <script type="text/javascript" src="include/profile.js"></script> In IE8 with "Compatibility View," the file never loads. The first line in the file is a simple alert() call, so that I know it loaded. Change the browser to Standards View, and it loads fine. Also, if I add: <meta http-equiv="X-UA-Compatible" content="IE=100" > It forces to Standards View and it loads fine. Any idea why this would be the case? I've not been able to test against IE7, but I know the JS file also does not load in IE6. Right now the tag is in the section of the file.

• PyQt4 Move QTableWidget row with widgets

  - by Guard

  I have the following method in my PyQt4 app. r2 is the number of row to move, and r1 is the position where it should be moved. To clarify: the table is filled with cellWidgets, not widgetItems. def move_row(self, r1, r2): tt = self.tableWidget tt.insertRow(r1) for c in range(tt.columnCount()): tt.setCellWidget(r1, c, tt.cellWidget(r2 + 1, c)) tt.removeRow(r2 + 1) # <--- ??? If I comment out the last line, it behaves as expected: the new row is inserted at position r1, it is filled with widgets from r2 (now it's r2+1), and the r2+1 row is empty. If I even hide this row, it behaves well, though it is not what I want (I have the rows numbered, and I don't want this hidden row to occupy the number). But if I remove the row, the widgets initially owned by it disappear. Looks like their ownership is taken on first placement, and is not changed after the move. Any ideas?

• Handling inverted pixels in bitmapData and bitmap class in as3

  - by intoTHEwild

  I am using bitmapData and bitmap classes to render a mouse cursor on the display screen. The bitmapData consists of an area whose colors should be inverted according to the background color. This is a very basic thing which could be observed with text cursor(the vertical line with two small horizontals on top and bottom), when moved over the text area. I want to be able to do the same with the pixels in my bitmapData, is there a way to find out the background color effectively and invert the color values? In this process i will be redrawing the whole pixels, is there any other efficient way to do that ?

• How to use MySql date_add in Nhibernate?

  - by jalchr

  This really puzzled for hours, I searched all over the internet, but got no working solution. Can someone point where the problem is ... thanks ! I created my own dialect class public class MySQLDialectExtended : MySQLDialect { public MySQLDialectExtended() { RegisterFunction("date_add_interval", new SQLFunctionTemplate(NHibernateUtil.Date, "date_add(?1, INTERVAL ?2 ?3)")); } } Then I try to use it as follows: query.Append( " ( date_add_interval(D.ApprovalDate, 1, YEAR) < current_timestamp() < date_add_interval(D.RenewalDate, -1, YEAR) )"); It fails with following exception: NHibernate.Hql.Ast.ANTLR.QuerySyntaxException : Exception of type 'Antlr.Runtime.NoViableAltException' was thrown. near line 1, column 677 where the column number is at the end of the first 'YEAR' word.

• Is it possible to replace groovy method for existing object?

  - by Jean Barmash

  The following code tried to replace an existing method in a Groovy class: class A { void abc() { println "original" } } x= new A() x.abc() A.metaClass.abc={-> println "new" } x.abc() A.metaClass.methods.findAll{it.name=="abc"}.each { println "Method $it"} new A().abc() And it results in the following output: original original Method org.codehaus.groovy.runtime.metaclass.ClosureMetaMethod@103074e[name: abc params: [] returns: class java.lang.Object owner: class A] Method public void A.abc() new Does this mean that when modify the metaclass by setting it to closure, it doesn't really replace it but just adds another method it can call, thus resulting in metaclass having two methods? Is it possible to truly replace the method so the second line of output prints "new"? When trying to figure it out, I found that DelegatingMetaClass might help - is that the most Groovy way to do this?

• What encoding I should use in editor (NetBeans), if I were intend to print non-english character

  - by Yan Cheng CHEOK

  I try to set the encoding of my editor to UTF-16. (Java String store the data in UTF-16 internally, right?) And I type the following code package helloworld; /** * * @author yan-cheng.cheok */ public class Main { /** * @param args the command line arguments */ public static void main(String[] args) { // TODO code application logic here System.out.println("???"); System.out.println("\u6587\u4EF6\u79CD\u7C7B"); } } However, the output is not what I expected : ???? ????? I try to change the editor encoding format to UTF-8, it works this time! ??? ???? May I know why I need to change the editor encoding format to UTF-8 but not UTF-16? Isn't Java String store the data in UTF-16 internally?

• AS3 TextField - unwanted carriage return when setting value to ""

  - by jevinkones

  I have an input TextField and have a KeyboardEvent.KEY_DOWN even listener on the stage to listen for the Keyboard.ENTER event. The event listener adds the entered text to an array or whatever, and then clears the TextField. The problem is that when the Enter key event fires and the TextField value is set to "", it leaves a carriage return in the TextField and the cursor positioned on the second line. WTF? I've been coding AS2 and AS3 for a LONG time and have never ran into this before. Am I losing my mind? Please help, people! :-) Example: var myTextArray:Array = new Array(); stage.addEventListener(KeyboardEvent.KEY_DOWN, onKeyDown); function onKeyDown(e:KeyboardEvent):void{ if(e.keyCode == Keyboard.ENTER){ if(_inputText.text != null){ myTextArray.push(_inputText.text); } _inputText.text = ""; } }

• Regex to identify rows that do not contain exact number of occurences of quotemark character using Notepad++

  - by SamAspin

  I would like to be able to jump to rows that dont contain 6 quotemarks in a quoted-CSV file as it feels like a good way to identify broken rows. I think using a regular expression with Notepad++'s find features would be a sensible approach but I'm not sure how to pick the rows up. 6 quotemarks (") would suggest a complete row so I want to skip to any row that does not contain 6. Here is some sample data to play with, in this example its the 4th line I'd like to jump to "sam","mark","dave" "sam","mark","dave" "sam","mark","dave" "sam","mark"," dave" "sam","mark","dave" "sam","mark","dave"

• How to get java to recognize symbolic links under cygwin

  Here's a very simple java program to print the first line of a file: import java.io.* public class test { public static void main(String[] args) throws IOException { System.out.print(new BufferedReader(new FileReader(args[0])).readLine()); } } When I run this program under cygwin and pass it the name of a symbolic link, it prints the contents of the symbolic link, not the target of that link: $ echo foo > testfile $ ln -s testfile symlink_to_testfile $ java test testfile foo $ java test symlink_to_testfile !<symlink> ?t e s t f i l e How do I convince java to follow the symlink? I was hoping there was something simpler than implementing the redirect myself.

• How can I extract URLs from plain text with Perl?

  - by Russell C.

  I need the Perl regex to parse plain text input and convert all links to valid HTML HREF links. I've tried 10 different versions I found on the web but none of them seen to work correctly. I also tested other solutions posted on StackOverflow, none of which seem to work. The correct solution should be able to find any URL in the plain text input and convert it to: <a href="$1">$1</a> Some cases other regular expressions I tried didn't handle correctly include: URLs at the end of a line which are followed by returns URLs that included question marks URLs that start with 'https' I'm hoping that another Perl guy out there will already have a regular expression they are using for this that they can share. Thanks in advance for your help!
