  • Display ñ on a C# .NET application

    - by mmr
    I have a localization issue. One of my industrious coworkers has replaced all the strings throughout our application with constants that are contained in a dictionary. That dictionary gets various strings placed in it once the user selects a language (English by default, but target languages are German, Spanish, French, Portuguese, Mandarin, and Thai). For our test of this functionality, we wanted to change a button to include text which has a ñ character, which appears both in Spanish and in the Arial Unicode MS font (which we're using throughout the application). Problem is, the ñ is appearing as a square block, as if the program did not know how to display it. When I debug into that particular string being read from disk, the debugger reports that character as a square block as well. So where is the failure? I think it could be in a few places: 1) Notepad may not be unicode aware, so the ñ displayed there is not the same as what vs2008 expects, and so the program interprets the character as a square (EDIT: notepad shows the same characters as vs; ie, they both show the ñ. In the same place.). 2) vs2008 can't handle ñ. I find that very, very hard to believe. 3) The text is read in properly, but the default font for vs2008 can't display it, which is why the debugger shows a square. 4) The text is not read in properly, and I should use something other than a regular StreamReader to get strings. 5) The text is read in properly, but the default String class in C# doesn't handle ñ well. I find that very, very hard to believe. 6) The version of Arial Unicode MS I have doesn't have ñ, despite it being listed as one of the 50k characters by http://www.fileinfo.info. Anything else I could have left out? Thanks for any help!

    I read some struts2 variable in javascript as follows: <javascript type="text/javascript"> var data='<s:property value="simulationInfos"/>'; <javascript> If my simulationInfos contains single quote ', I get the error : unexpected identifier. therefore, I tried to escape the quote as follows: var data='<s:property value="simInfos" escapeJavaScript="true"/>'; and var data='<s:property value="simInfos" escapeHTML="true"/>'; I get the error: Attribute escapeJavaScript (or escapeHTML) invalid for tag property according to TLD. Any Idea?

  • question about InnoDB deadlock in MySQL?

    - by WilliamLou
    I found this kind of interesting problem in MySQL InnoDB engine, could anyone explain why the engine always claim it's a deadlock. First, I created a table with a single row, single column: CREATE TABLE `SeqNum` (`current_seq_num` bigint(30) NOT NULL default '0', PRIMARY KEY (`current_seq_num`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8 | Now, I have two MySQL connector threads, In thread1: mysql> begin; Query OK, 0 rows affected (0.00 sec) mysql> select `current_seq_num` into @curr_seq FROM SeqNum FOR UPDATE; Query OK, 1 row affected (0.00 sec) Now, in thread2, I did the exactly same: mysql> begin; Query OK, 0 rows affected (0.00 sec) mysql> select `current_seq_num` into @curr_seq FROM SeqNum FOR UPDATE; before the default innodb_lock_wait_timeout, the thread2 just wait for thread1 to release its exclusive lock on the table, and it's normal. However, in thread1, if I input the following update query: mysql> update SeqNum set `current_seq_num` = 8; ERROR 1213 (40001): Deadlock found when trying to get lock; try restarting transaction Now, thread2 get the select query finished because thread1 quits. In addition, in thread1, if I input the update query with a where clause, it can be executed very well: mysql> update SeqNum set `current_seq_num` = 8 where `current_seq_num` =5 Query OK, 1 row affected (0.00 sec) Could anyone explain this?

  • cakephp, i18n .po files, How to use them correctly

    - by ion
    I have finally managed to set up a multilingual cakephp site. Although not finished it is the first time where I can change the DEFAULT_LANGUAGE in the bootstrap and I can see the language to change. My problem right now is that I cannot understand very well how to use the po files correctly. According to the tutorials I've used I need to create a folder /app/locale and inside that folder create a folder for each language in the following format: /locale/eng/LC_MESSAGES. I have done that and I have also managed to extract a default.pot file using cake i18n extract. And it appears that all occurrences of the __() function have been found succesfully. In my application I'm using 2 languages: eng and gre. I can see why you would need a seperate folder for each language. However in my case nothing happens when I edit the po files inside each folder....well almost nothing. If I edit the /app/locale/gre/LC_MESSAGES/default.po I have no language changes. If I edit the /app/locale/eng/LC_MESSAGES/default.po then the language changes to the new value (on the translation field) and it does not switch to the other language. What am I doing wrong. I hope I made myself as clear as possible.

  • Why can't I set a custom color-tint for the UINavigationBar?

    - by mobibob
    I want to change the color on the navigation bar and the documentation states not to attempt to change the 'alpha' value. So, how can I set a color that is not the SDK defined values (e.g., [UIColor redColor], brownColor, etc.) if all the constructors provide an alpha value? I tried getting the current alpha value but that did not help. When I use a custom color, it causes the navigation bar to look like an x-ray (a scraggy, black-on-white). [self.navigationController.navigationBar setTintColor: [UIColor brownColor]];

  • !(ReferenceEquals()) vs != in Entity Framework 4

    - by Eric J.
    Unless a class specifically overrides the behavior defined for Object, ReferenceEquals and == do the same thing... compare references. In property setters, I have commonly used the pattern private MyType myProperty; public MyType MyProperty { set { if (myProperty != value) { myProperty = value; // Do stuff like NotifyPropertyChanged } } } However, in code generated by Entity Framework, the if statement is replaced by if (!ReferenceEquals(myProperty, value)) Using ReferenceEquals is more explicit (as I guess not all C# programmers know that == does the same thing if not overridden). Is there any difference that's escaping me between the two if-variants? Are they perhaps accounting for the possibility that POCO designers may have overridden ==? In short, if I have not overridden ==, am I save using != instead of ReferencEquals()?

  • Chnaging Displayed Image on a Webpage Using Javascript

    - by Gavin
    Hi all, I'm having some trouble changing an image being displayed on a page by way of a dropdown menu selection. This works fine.. getting the dropdown menu to give me an alert when I make a selection. Even though the menu is embedded within a division, paragraph, and label tag, it still works. "availableImages" is the name of my menu. function imageSelect() { var index = document.getElementById("myForm").availableImages.selectedIndex; var value = document.getElementById("myForm").availableImages.options[index].value; alert("test " + value); // alert box pops up upon list item selection } However, within the same division, I am having an issue with changing the source of my image tag... Any ideas? I will provide more code if it will be helpful. Thanks! Gavin

  • a question on common lisp

    - by kostas
    Hello people, I'm getting crazy with a small problem here, I keep getting an error and I cant seem to figure out why, the code is supposed to change the range of a list, so if we give it a list with values (1 2 3 4) and we want to change the range in 11 to fourteen the result would be (11 12 13 14) the problem is that the last function called scale-list will give back an error saying: Debugger entered--Lisp error: (wrong-type-argument number-or-marker-p nil) anybody has a clue why? I use aquamacs as an editor thanks in advance ;;finds minimum in a list (defun minimum(list) (car (sort list #'<))) ;;finds maximum in a list (defun maximum(list) (car (sort list #'>))) ;;calculates the range of a list (defun range(list) (- (maximum list) (minimum list))) ;;this codes scales a value from a list (defun scale-value(list low high n) (+ (/ (* (- (nth (- n 1) list) (minimum list)) (- high low)) (range list)) low)) ;and this code is supposed to scale the whole list (defun scale-list(list low high n) (unless (= n 0) (cons (scale-value list low high n) (scale-list list low high (- n 1))))) (scale-list '(0.1 0.3 0.5 0.9) 20 30 4)

  • UrlEncoding-Safe Delimiter

    - by Aren B
    So the site I'm working on has a filter system that operates by passing a key and value system through a querystring. The whole site is going through a re-factor soon and I'm maintaining the existing site so before we discuss the RIGHT way to implement this, I just need ideas for changing my delimiter. The current format is like this: cf=<key>:<value> The problem is, I've recently run into an issue because some of our new values for this filter contain : in them. I.e: cf=MO_AspectRatio:16:10 The value is being UrlEncoded, but the browsers are de-coding %3a into : on the fly because the : doesn't inherently break the urls. I need some suggestions for url-safe delimiters that aren't :,-,_,&,? that makes sense. I'm not looking for a solution like () or something wild.

  • jQuery - change a list of elements to an associative array

    - by Brian M. Hunt
    Given an associative array (of the sort returned by jQuery.serializeArray()) like this: [ { 'name': 'abc', 'value': 'aaa', '__proto__': [Object] }, { 'name': 'def', 'value': 'bbb', '__proto__': [Object] }, { 'name': 'abc', 'value': 'ccc', '__proto__': [Object] } ] How can one convert this, using either jQuery or just javascript, to an associative array of name: [values] like this: { 'abc': ['aaa', 'ccc'], 'def': ['bbb'] } This seems to essentially be the inverse of this question: Build associative array based on values of another associative array... but in Javascript (not PHP). I wasn't able to find this question on Stackoverflow, though I thought it would have been asked. Thank you for reading. Brian

  • winforms - gridview cell timespan edit problem

    - by Sharique
    I'm following this question for formatting timespan value in the gridview. Format TimeSpan in DataGridView column I'm diaplying only minutes value in grid as follows DataGridViewColumn idleTimeColumn = myGridView.Columns["IdleTime"]; idleTimeColumn.DefaultCellStyle.FormatProvider = new TimeSpanFormatter(); idleTimeColumn.DefaultCellStyle.Format = "m"; This cell is editable, so when I enter 5 (that mean 5 min) in the cell, then it should take it minute, but it take it as day value (ie, 5.00:00:00). I tried different values for format (mm,%m) but all these gives the same output.

  • Get drive label in C#

    - by Rick
    When I use System.IO.DriveInfo.GetDrives() and look at the .VolumeLabel property of one of the drives, I see "PATRIOT XT", which is indeed the drive's volume label. If I open "My Computer", instead I see "TrueCrypt Traveler Disk", and I can't seem to find any way to programmatically retrieve that value as none of the DriveInfo properties hold that value. I also tried querying the information via WMI's Win32_LogicalDisk, but no properties contained that value there either. So any idea what the label My Computer uses is called, and more importantly, how to programmatically retrieve it? Thanks

  • How do I execute file installed by merge module?

    - by Juozas Kontvainis
    I am using WIX and have successfully used a custom action to execute installed file at the end of installer like this: <CustomAction Id="LaunchAfterInstall" FileKey="foobar.exe" ExeCommand="parameters" Execute="immediate" Impersonate="yes" Return="asyncNoWait" /> <Property Id="WIXUI_INSTALLDIR" Value="INSTALLLOCATION"/> <UIRef Id="WixUI_InstallDir" /> <Property Id="WIXUI_EXITDIALOGOPTIONALCHECKBOXTEXT" Value="Launch Foobar." /> <UI> <Publish Dialog="ExitDialog" Control="Finish" Order="1" Event="DoAction" Value="LaunchAfterInstall">WIXUI_EXITDIALOGOPTIONALCHECKBOX</Publish> </UI> This works well when foobar.exe is in a component in the same wxs file. However what I really want is to execute a file that is installed by a merge module. How do I do this? I can make changes in the merge module, if this helps things.

  • Ruby on Rails: strange voting increment behavior

    - by Justin Meltzer
    So I have an up and a downvote button that inserts a vote with a value of 1 or -1 into the database. This works correctly. Then, I display the total vote count for that element by summing up its votes' values. However, this isn't working correctly, because the vote sum display is acting really strange: The first vote on a video doesn't seem to increment it at all. Then the second vote does. If I go from an upvote to a downvote, it increments up once, and then the next downvote is down. This is difficult to explain, but maybe you can figure out what is wrong with my code. I have this function in my Video model (the element that is voted on, it has_many video_votes): def vote_sum read_attribute(:vote_sum) || video_votes.sum(:value) end I also have this in my VideoVote model: after_create :update_vote_sum private def update_vote_sum video.update_attributes(:vote_sum => video.vote_sum + value) end What am I doing wrong?

  • Scala method where type of second parameter equals part of generic type from first parameter

    - by ifischer
    I want to create a specific generic method in Scala. It takes two parameters. The first is of the type of a generic Java Interface (it's from the JPA criteria query). It currently looks like this: def genericFind(attribute:SingularAttribute[Person, _], value:Object) { ... } // The Java Interface which is the type of the first parameter in my find-method: public interface SingularAttribute<X, T> extends Attribute<X, T>, Bindable<T> Now i want to achieve the following: value is currently of type java.lang.Object. But I want to make it more specific. Value has to be the of the same type as the placeholder "_" from the first parameter (and so represents the "T" in the Java interface). Is that somehow possible, and how? BTW Sorry for the stupid question title (any suggestions?)

  • PHP: How to use mysql fulltext search and handle fulltext search result

    - by garcon1986
    Hello, I have tried to use mysql fulltext search in my intranet. I wanted to use it to search in multiple tables, and get the independant results depending on tables in the result page. This is what i did for searching. $query = " SELECT * FROM testtable t1, testtable2 t2, testtable3 t3 WHERE match(t1.firstName, t1.lastName, t1.details) against(' ".$value."') or match(t2.others, t2.information, t2.details) against(' ".$value."') or match(t3.other, t2.info, t2.details) against(' ".$value."') "; $result = mysql_query($query)or die('query error'.mysql_error()); while($row = mysql_fetch_assoc($result)){ echo $row['firstName']; echo $row['lastName']; echo $row['details'].'<br />'; } Do you have any ideas about optimizing the query and format the output of search results?

  • Ajax.BeginForm is submitting disabled form elements

    - by Fiffe
    Using MVC3 and Ajax.BeginForm I surprisingly discovered that mvc ajax forms submits elements with the attribute disabled="disabled". I have tested both select and text inputs. I was suprised because they should not be submited and they will not when using Html.BeginForm. Is there some hidden option or a workaround for this? [EDIT example] @using (Ajax.BeginForm("Action", "Control", new AjaxOptions() { HttpMethod = "POST" })) { <input type="text" name="_enabled" value="_enabled" /> <input type="text" name="_disabled" value="_disabled" disabled="disabled" /> <input type="submit" value="POST" /> }

  • Why Does Thread.CurrentThread.CurrentCulture Change between Page Rendering and HttpModule.PostReques

    - by Chad
    I'm creating an HttpModule that needs to know the value of Thread.CurrentThread.CurrentCulture as set in an MVC application. That value is currently being set by the BaseController, but when my HttpModule.PostRequestHandlerExecute() method fires, it reverts to what the Culture was prior to page rendering. I have duplicated this by creating a simple web app with these steps: Module.PreRequestHandlerExecute: Set culture to A Page_Load: Culture is currently A. Set culture to B Module.PostRequestHandlerExecute: Current thread culture is A. I expected it to be B but it was changed between page rendering and PostRequestHandlerExecute Any idea why .Net changes this value or how I could get around it? The thread is the same, so something in .Net must be explicitly reverting the culture.

  • Qt QFileDialog - native dialogs only with static functions?

    - by darron
    I'm trying to simply save a file. However, I need a filename entered without a suffix to automatically get a default suffix (which setDefaultSuffix() does). I'd rather not completely lose the native save dialog just for this. exec() is not overloaded from QDialog, so it totally bypasses the native hook (ignoring the DontUseNativeDialog option even if it's false). If I disable the file overwrite warning and append the default suffix myself after the function returns, then I'd be re-opening the dialog if the user did not want to overwrite... and that's just ugly. Is there some signal I can catch and quickly inject the default suffix if it's not there? I'm guessing not, since it's a native dialog. Is there something I'm doing wrong with the filter? I only have one filter choice. It should use that extension. This seems pretty lame. Launching the save dialog and simply typing "test" should never result in an extensionless file. "test.", yes. "test" no way. That'll really confuse the users when they hit Load and can't see the file they just saved. I guess the cross-platform part of Qt is giving me lowest common denominator file dialog functionality?

  • nmake.exe: is there a way to exclude a file from a set of files specified in a macro?

    - by Cheeso
    I'm looking for something like the Exclude filter for msbuild, but I Want it in a makefile processed by nmake. Is that possible? Suppose I have a makefile that defines this macro: SOURCES=xxx.c yyy.c zzz.c and I invoke it with nmake OLD=xxx.c NEW=bbb.c ...can I produce, within the makefile, a macro with a value like: yyy.c zzz.c bbb.c ...basically substituting bbb.c for xxx.c ? The files can appear in any order. This would be pretty easy if the string substitution that is possible in nmake macros, allowed for evaluation of macros. In other words, I can do sources=xxx.c yyy.c zzz.c objs=$(sources:.c=.o) and the value of $(objs) is xxx.o yyy.o zzz.o But nmake does not allow a macro for the value of either argument to that substitution. I cannot do this: new=.o sources=xxx.c yyy.c zzz.c objs=$(sources:.c=$(new))
