• asp.net compare validators to allow comma and dot (both!) as decimal separator

  - by DanC

  I am using a compare validator, which validates that the entered number is a valid double and also validates it against a given value (greater than zero). I am validating money amounts. Because of the location where the app is used, the locale sets the comma as the decimal separator. The problem is that when a user enters the value using the numeric keyboard, the number gets written with the dot as decimal separator, and is rejected by the validation. I'd like to have this validation done before triggering a postback (like a customvalidator would) and accepting both separators. Any ideas? Thanks

• Can I get build warnings from a custom build step in Qt Creator?

  - by Derick

  I have the following script that I run as a custom build step in Qt Creator: git ls-files . | egrep "\.cpp$|\.h$" | xargs vera++ Which then gives output: foo/bar.cpp:1: no copyright notice found Another script I also use is: cppcheck . --template gcc -q --enable=style,unusedFunctions With the output: apple.h:8: style: The class 'MyPie' has no constructor. Member variables not initialized. I would love to double-click on the error and go to the source in the Compile Output window. It seems that only gcc errors are detected and these custom ones are ignored even though they have the same format.

• Configuration Log4j: ConsoleAppender to System.err?

  - by Gerard

  I saw that one of our tools uses a ConsoleAppender to System.err next to System.out in it's log4j configuration. Fragments of the configuration: <appender name="CONSOLE" class="org.apache.log4j.ConsoleAppender"> <!-- Log to STDOUT. --> <param name="Target" value="System.out"/> .... <appender name="CONSOLE_ERR" class="org.apache.log4j.ConsoleAppender"> <!-- Log to STDERR. --> <param name="Target" value="System.err"/> In Eclipse this results in double messages to the console, so I believe that is of no use, right? On the Linux server I see only one message to the PuTTY console, so where would that System.err message go to?

• help me to cheat with numericUpDown1_ValueChanged event

  - by alex

  I have a Form and numericupdown control located on it. I want that in some conditions (_condition1) user cannot be able to change a value of numericupdown control. How can I do it ? I wrote some code but it works twice (double time). class Form1 : Form { bool _condition1; int _previousValue; void numericUpDown1_ValueChanged(object sender, EventArgs e) { if(_condition1) { numericUpDown1.Value = (decimal)_previousValue; } else { _previousValue = (int)numericUpDown1.Value; } } } Control must be enable.

• FormEditor receiving NULL IEditorInput object

  - by Gabriel Parenza

  Hi, I have extended IEditorInput class to define my own IEditorInput object. Furthermore, I have extended FormEditor class. I have view where I am displaying my application objects. Whenever user double clicks on items on view, I intend to display more details for this application object on the editor, which is a FormEditor. Problem I am facing is that I am receiving IEditorInput object as NULL inside extended FormEditor class. Can someone please tell me what I am doing wrong? Code: CustomFormEditor extends FormEditor CustomEditorInput extends IEditorInput In View class: PlatformUI.getWorkbench().getActiveWorkbenchWindow().getActivePage().openEditor(new CustomEditorInput("test"),"editor.id"); Thanks, Gaurav.

• Cleaning up nasty characters in PHP

  - by Simon Hume

  Hi folks, Got a little issue where my client is pasting in content from Word into my little text editor in a CMS. The double quotes are coming back encoded in what looks like some form of UTF. Any ideas if I can strip/replace these using PHP when they get displayed out of my mySQL table. Here is the link to the page that spits out the dodgy characters, you can see the 'black diamonds of doom' which are causing the headaches. http://linq.milkbarstudios.com/news_detail.php?id=3 Any suggestions would be greatly accepted!

• Sample the deltas between values using boost::accumulators

  - by Checkers

  I have a data set with N integers (say, 13, 16, 17, 20) where each next sample is incremented by some value (3, 1, 3 in this case) and I want to use boost::accumulators::accumulator_set to find various statistics of the second sequence. I want to be able to do something like this: accumulator_set< double, features< tag::mean > > acc; ... acc(13); acc(16); acc(17); acc(20); ...BUT sampling the differences instead of the actual values. How can I do that with accumulator_set without keeping track of the last value manually?

• Would an ORM have any way of determining that a SQLite column contains date-times or booleans?

  - by DanM

  I've been thinking about using SQLite for my next project, but I'm concerned that it seems to lack proper datetime and bit data types. If I use DbLinq (or some other ORM) to generate C# classes, will the data types of the properties be "dumbed down"? Will date-time data be placed in properties of type string or double? Will boolean data be placed in properties of type int? If yes, what are the implications? I'm envisioning a scenario where I need to write a whole second layer of classes with more specific data types and do a bunch of transformations and casts, but maybe it's not as bad as I fear. If you have any experience with this or a similar scenario, how did you handle it?

• Overriding events of excel sheet using VBA

  - by Rashmi Pandit

  Hi, I need to programmatically override the following events of a worksheet: BeforeDoubleClick SelectionChange BeforeRightClick I have been able to override the OnActivate event using the following code: sheet.OnSheetActivate = "MyOwn_Activate" Private Sub MyOwn_Activate() myForm.Show End Sub I have implemented BeforeDoubleClick on similar lines: sheet.OnDoubleClick = "My_BeforeDoubleClick" Private Sub My_BeforeDoubleClick(ByVal Target As Range, Cancel As Boolean) ... End Sub However, an 'argument not optional' error is thrown at run-time when user double clicks a cell on the sheet. Can someone please suggest how should I pass the paramters? In addition, I am not able to find event names for SelectionChange & BeforeRightClick. I tried: sheet.BeforeRightClick = "My_BeforeRightClick" sheet.SelectionChange = "My_SelectionChange" But, both the above lines do not work. Any help/ suggestion is greatly appreciated. Thanks :)

• Strange Scala error.

  - by Lukasz Lew

  I tried to create abstract turn based Game and abstract AI: abstract class AGame { type Player type Move // Player inside def actPlayer : Player def moves (player : Player) : Iterator[Move] def play (move : Move) def undo () def isFinished : Boolean def result (player : Player) : Double } abstract class Ai[Game <: AGame] { def genMove (player : Game#Player) : Game#Move } class DummyGame extends AGame { type Player = Unit type Move = Unit def moves (player : Player) = new Iterator[Move] { def hasNext = false def next = throw new Exception ("asd") } def actPlayer = () def play (move : Move) { } def undo () { } def isFinished = true def result (player : Player) = 0 } class DummyAi[Game <: AGame] (game : Game) extends Ai[Game] { override def genMove (player : Game#Player) : Game#Move = { game.moves (player).next } } I thought that I have to use this strange type accessors like Game#Player. I get very puzzling error. I would like to understand it: [error] /home/lew/Devel/CGSearch/src/main/scala/Main.scala:41: type mismatch; [error] found : Game#Player [error] required: DummyAi.this.game.Player [error] game.moves (player).next [error] ^

• Is there Java counterpart for Aspnet 4's <%: %> XSS prevention?

  - by Tomas Tintera

  I'm developer moving from C# to Java. Heard about new ASP net feature. <%: %. It renders object with html encoding. Only these impolementing IHtmlString interface are not encoded (to prevent double encoding). See more in http://weblogs.asp.net/scottgu/archive/2010/04/06/new-lt-gt-syntax-for-html-encoding-output-in-asp-net-4-and-asp-net-mvc-2.aspx Is such cute tool in Java side? I mean a way to output a string to webpage and (not)encode it based on it's type.

• Escaping ampersands in URLs for HttpClient requests

  - by jpatokal

  So I've got some Java code that uses Jakarta HttpClient like this: URI aURI = new URI( "http://host/index.php?title=" + title + "&action=edit" ); GetMethod aRequest = new GetMethod( aURI.getEscapedPathQuery()); The problem is that if title includes any ampersands (&), they're considered parameter delimiters and the request goes screwy... and if I replace them with the URL-escaped equivalent %26, then this gets double-escaped by getEscapedPathQuery() into %2526. I'm currently working around this by basically repairing the damage afterward: URI aURI = new URI( "http://host/index.php?title=" + title.replace("&", "%26") + "&action=edit" ); GetMethod aRequest = new GetMethod( aURI.getEscapedPathQuery().replace("%2526", "%26")); But there has to be a nicer way to do this, right? Note that the title can contain any number of unpredictable UTF-8 chars etc, so escaping everything else is a requirement.

• Possible: Set Operations on Disparate Maps with Same Key Type?

  - by Catskul

  Let's say I have two maps: typedef int Id; std::map<Id, std::string> idToStringMap; std::map<Id, double> idToDoubleMap; And let's say I would like to do a set operation on the keys of the two maps. Is there an easier way to do this than to create a custom "inserter" iterator? such that I could do something like: std::set<Id> resultSet; set_difference( idToStringMap.begin(), idToStringMap.end(), idToDoubleMap.begin(), idToDoubleMap.end(), resultSet.begin() ); My experimentation results imply that it will be necessary to create a custom inserter and perhaps a custom key comparer to do this, but I want for some insight/shortcut before doing so.

• What's the fastest way to check the availability of a SQL Server server?

  - by mwolfe02

  I have an MS Access program in use in multiple locations. It connects to MS SQL Server tables, but the server name is different in each location. I am looking for the fastest way to test for the existence of a server. The code I am currently using looks like this: ShellWait "sc \\" & ServerName & " qdescription MSSQLSERVER > " & Qt(fn) FNum = FreeFile() Open fn For Input As #FNum Line Input #FNum, Result Close #FNum Kill fn If InStr(Result, "SUCCESS") Then ... ShellWait: executes a shell command and waits for it to finish Qt: wraps a string in double quotes fn: temporary filename variable I run the above code against a list of server names (of which only one is normally available). The code takes about one second if the server is available and takes about 8 seconds for each server that is unavailable. I'd like to get both of these lower, if possible, but especially the fail case as this one happens most often.

• WPF DependencyProperty event before content changed

  - by morsanu

  First I will explain the context of the problem, because you might be able to point me in a better direction. I need to implement a undo-redo like system on an object. The object has a series of dependency properties. Some are double, int, string but some are also of DependencyObject type. I need to save the value of the property before it is changed, and for this I added the CoerceValueCallback. public static readonly DependencyProperty MyBackgroundProperty = DependencyProperty.Register("MyBackground", typeof(MyCustomizableBackground), typeof(MyComponent), new UIPropertyMetadata(default(MyCustomizableBackground), null, new CoerceValueCallback(OnPropertyChanged))); In OnPropertyChanged I save the value before it's changed. MyCustomizableBackground is the DependencyObject that has also some dependency properties. The problem is that in this case, where I have a custom object as a property, the OnPropertyChanged method isn't triggered, but when I have a common type, it is triggered.

• How to Access a Private Variable?

  - by SoulBeaver

  This question isn't meant to sound as blatantly insulting as it probably is right now. This is a homework assignment, and the spec sheet is scarce and poorly designed to say the least. We have a function: double refuel( int liter, GasStation *gs ) { // TODO: Access private variable MaxFuel of gs and decrement. } Sound simple enough? It should be, but the class GasStation comes with no function that accesses the private variable MaxFuel. So how can I access it anyway using the function refuel? I'm not considering creating a function setFuel( int liter ) because the teacher always complains rather energetically if I change his specification. So... I guess I have to do some sort of hack around it, but I'm not sure how to go about this without explicitely changing the only function in GasStation and giving it a parameter so that I can call it here. Any hints perhaps?

• App with MVC Virtual application shared AuthCookie.

  - by Razcer

  I have a 3.5 ASP.Net WebForm parent application. The parent uses forms authentication. I have a MVC child virtual application, I would like to make it so the user logs in to the parent application, user then navigates to the virtual application by pressing a link on the parent. However every time I do this it goes to the login screen for the virtual application. Is there a web setting I should double check in Parent? Or Child? Is there an IIS setting that I should check? Should I be using a virtual directory instead of virtual application? I want the child to be able to access the Session[] from the parent. I would like the child app to use the same authCookie as the parent app.

• Interface Builder - XCode link broken with iPad-converted xib

  - by Kenneth Ballenegger

  In porting my app to a universal iPhone / iPad app, the xibs I created by using Interface Builder's "Create iPad Version" will not link to the project properly: They don't pick up on classes and images from the project file. IB tells me that "there is no xcode project associated with this document" with a gray light in the status bar. Yet the xib is in the project, was launched by double-clicking in xcode, and both are open. The old xibs work fine though. I don't understand what could be causing this. So, my question is, how do I restore the link?

• How can I avoid floating the same content twice?

  - by Randall Bohn

  My Kynetx app uses float_html() to put up a box full of content. rule float_box { select when pageview ".*" pre { content = << <div id='messagebox'> <h3>Floating Message Box</h3> <ul id='my_list'></ul> </div> >>; } float_html("absolute","top:25px","right:20px",content); } rule fill_box { select when pageview ".*" foreach ["alpha","bravo","charlie"] setting (list_item) append("#my_list", "<li>#{list_item}</li>"); } The app (a421x27) is used from a bookmarklet. If you click the bookmarklet twice on the same page you get double content. Is there any way to detect that the box is already on the screen and reuse it?

• Grouping rectangles (getting the bounding boxes of rects)

  - by hyn

  What is a good, fast way to get the "final" bounding boxes of a set of random (up to about 40, not many) rectangles? By final I mean that all bounding boxes don't intersect with any other. Brute force way: in a double for loop, for each rect, test for intersection against every other rect. The intersecting rects become a new rect (replaced), indicating the bounding box. Start over and repeat until no intersection is detected. Because the rects are random every time, and the rect count is relatively small, collision detection using spatial hashing seems like overkill. Is there a way to do this more effectively?

• xval get message from resource file

  - by Rob

  I'm working on a CMS system which uses a resource file to get information and errormessages from. The client side validation is working without problems, only it's not getting the errormessage from the resource file. While debugging i figured out xval seems to get the errormessages from a javascript file where the messages are set hard-coded. Is there some way to override this? Below the code which should make the relation to the resourcefile en specify the error when the field is left empty. [Property] [Required(ErrorMessageResourceType = typeof(CMSMessages), ErrorMessageResourceName = "EnterValidMoney")] public virtual Double ShippingCost { get; set; }

• Permanent remove of logo in Windows Scripting Host (WSH() scripts.

  - by antonio

  I know two ways to remove the logo permanently. The "official" one: cscript //Nologo //S Will save current command line options for current user. A ftype approach with admin privileges: ftype wsffile="%SystemRoot%\System32\CScript.exe" //nologo "%%1" %%* ftype jsfile="%SystemRoot%\System32\CScript.exe" //nologo "%%1" %%* ftype vbsfile="%SystemRoot%\System32\CScript.exe" //nologo "%%1" %%* Double-%'s are needed only if you use the lines in a batch file. The latter will all users via affect the reg key HKEY_CLASSES_ROOT\<file>\Shell\Open\Command, where <file> can be wsffile, jsfile or vbsfile. Do you know where are stored the cscript //Nologo //S settings?
