  • FindControl() method throws ArithmeticException?

    - by Mark Struzinski
    I have a line of C# in my ASP.NET code behind that looks like this: DropDownList ddlStates = (DropDownList)fvAccountSummary.FindControl("ddlStates"); The DropDownList control is explicitly declared in the markup on the page, not dynamically created. It is inside of a FormView control. When my code hits this line, I am getting an ArithmeticException with the message "Value was either too large or too small for an Int32." This code has worked previously, and is in production right now. I fired up VS2008 to make some changes to the site, but before I changed anything, I got this exception from the page. Anyone seen this one before?

  • File sorting, Comparison method violates its general contract

    - by user2677383
    My file sorting comparator sometimes invoke java.lang.IllegalArgumentException in android app. I cannot figure out the reason. could you explain that? here is my code block: Comparator cc = new Comparator<File>() { @Override public int compare(File f1, File f2) { if (f1.isDirectory() && !f2.isDirectory()) { return 1; } if (f2.isDirectory() && !f1.isDirectory()) { return -1; } if ((f1.isFile() && f2.isFile()) || (f1.isDirectory() && f2.isDirectory())) { if (sort == 1) { return Util.compareFileName(f2.getName(), f1.getName()); } else if (sort == 2) { return (int) (f1.lastModified() - f2.lastModified()); } else if (sort == 3) { return (int) (f2.lastModified() - f1.lastModified()); } else if (sort == 4) { return (int) (f1.length() - f2.length()); } else if (sort == 5) { return (int) (f2.length() - f1.length()); } else return Util.compareFileName(f1.getName(), f2.getName()); } return f1.compareTo(f2); } }; Util.compareFileName is as followings: public static int compareFileName(String s1, String s2) { int thisMarker = 0; int thatMarker = 0; int s1Length = s1.length(); int s2Length = s2.length(); while (thisMarker < s1Length && thatMarker < s2Length) { String thisChunk = getChunk(s1, s1Length, thisMarker); thisMarker += thisChunk.length(); String thatChunk = getChunk(s2, s2Length, thatMarker); thatMarker += thatChunk.length(); // If both chunks contain numeric characters, sort them numerically int result = 0; if (isDigit(thisChunk.charAt(0)) && isDigit(thatChunk.charAt(0))) { // Simple chunk comparison by length. int thisChunkLength = thisChunk.length(); result = thisChunkLength - thatChunk.length(); // If equal, the first different number counts if (result == 0) { for (int i = 0; i < thisChunkLength; i++) { result = thisChunk.charAt(i) - thatChunk.charAt(i); if (result != 0) { return result; } } } } else { result = thisChunk.compareTo(thatChunk); } if (result != 0) return result; } return s1Length - s2Length; }

  • naming a method - using set() when *not* setting a property?

    - by user151841
    Is setX() method name appropriate for only for setting class property X? For instance, I have a class where the output is a string of an html table. Before you can you can call getTable, you have to call setTable(), which just looks at a other properties and decides how to construct the table. It doesn't actually directly set any class property -- only causes the property to be set. When it's called, the class will construct strHtmlTable, but you can't specify it. So, calling it setTable breaks the convention of get and set being interfaces for class properties. Is there another naming convention for this kind of method? Edit: in this particular class, there are at least two ( and in total 8 optional ) other methods that must be called before the class knows everything it needs to to construct the table. I chose to have the data set as separate methods rather than clutter up the __construct() with 8 optional parameters which I'll never remember the order of.

  • Convert user input into ToString() method inside FlowDocument in Workflow 4.0

    - by Jon Ownbey
    I have a Workflow 4.0 app that generates emails. In a dialog for creating the email body the user needs to be able to input some string value representing an existing wf instance variable to be inserted as a string at runtime. So they input something like: Email body text including <. (say ExistingVariable is an int or something like that) Any helpful hints for how to convert this text with a ToString() at runtime?

  • How good is the Rails sanitize() method?

    - by Horace Loeb
    Can I use ActionView::Helpers::SanitizeHelper#sanitize on user-entered text that I plan on showing to other users? E.g., will it properly handle all cases described on this site? Also, the documentation mentions: Please note that sanitizing user-provided text does not guarantee that the resulting markup is valid (conforming to a document type) or even well-formed. The output may still contain e.g. unescaped ’<’, ’’, ’&’ characters and confuse browsers. What's the best way to handle this? Pass the sanitized text through Hpricot before displaying?

  • Change css class depending on label's text

    - by abatishchev
    I have asp:Table with number of asp:Label inside asp:FormView, it represents short stats info. I need to set Label.CssClass to "red" if it's text isn't "0". Currently I do this on FormView.DataBound event. But think that it's better to use JavaScript and probably jQuery. How can I do that?

  • comma in regex in String.replaceAll() method?

    - by kknight
    My code tries to replace "," with "/" in a string. Should I escape "," in the regex string? Both of the two code snippets generated the same results, so I am confused. Code snippet 1: String test = "a,bc,def"; System.out.println(test.replaceAll("\\,", "/")); Code snippet 2: String test = "a,bc,def"; System.out.println(test.replaceAll(",", "/")); Should I use "," or "\,"? Which is safer? Thanks.

  • Calling a method on a Object says "disallows late binding"

    - by Maury Markowitz
    I have a calls called DtaDate that stores an integer "key", a string name, a string for the date, and a Date object that is created from that string. I have some code that needs to accept a date-like object. I'd like the user to be able to pass in anything date like - a Date object which I'll extract the information from, another DtaDate, a string with the date in it, or even the key, which I'll use to look up the DtaDate from a collection. So I have this: Friend Sub New(NameIn As String, DateFormulaIn As String, Optional FromDateIn As Object = Nothing) [stuff that works] [check that we got a FromDateIn...] If TypeOf FromDateIn Is DtaDate Then fdk = FromDateIn.Key Ans.FromDate = fdk VB tells me that "Option Strict On disallows late binding". The other cases, where a string or integer is the TypeOf, I use CInt or CStr. But this is the first time I've actually run into a case where the casting is a non-base type. What's the trick?

  • Is it possible to access the line of code where a method is called from within that method?

    - by Dan Tao
    Disclaimers: I am not interested in doing this in any real production code. I make no claim that there's a good reason why I'm interested in doing this. I realize that if this is in any way possible, it must involve doing some highly inadvisable things. That said... is this possible? I'm really just curious to know. In other words, if I have something like this: int i = GetSomeInteger(); Is there any way from within GetSomeInteger that the code could be "aware of" the fact that it's being called in an assignment to the variable i? Again: no interest in doing this in any sort of real scenario. Just curious!

  • Grails problem with nullable contraint in domain class

    - by xain
    Hi, I'm having the following problem with grails' 1.2.1 domain classes: When I set a constraint attr(nullable:true) and attr is int or bool, this condition isn't reflected in the db (postgresql 8.4). However, if attr is a String, the DB is consistent with the situation. Any hints ? Thanks

  • Is there a faster method to match an arbitrary String to month name in Java

    - by jonc
    Hello, I want to determine if a string is the name of a month and I want to do it relatively quickly. The function that is currently stuck in my brain is something like: boolean isaMonth( String str ) { String[] months = DateFormatSymbols.getInstance().getMonths(); String[] shortMonths = DateFormatSymbols.getInstance().getShortMonths(); int i; for( i = 0; i<months.length(); ++i;) { if( months[i].equals(str) ) return true; if( shortMonths[i].equals(str ) return true; } return false; } However, I will be processing lots of text, passed one string at a time to this function, and most of the time I will be getting the worst case of going through the entire loop and returning false. I saw another question that talked about a Regex to match a month name and a year which could be adapted for this situation. Would the Regex be faster? Is there any other solution that might be faster?

  • simple method that checks text is email with regular expression

    - by user223863
    Can't believe how difficult this seems to be all I want to is to validate a user inout using javascript to make sure that it is an email address. But can't get it to work: I am using: //validates a regulaer expression Utilities2.prototype.validateEmail = function(stringToValidateArg) { alert('about to check regexp'); var regExpPattern = /^[a-zA-Z0-9._-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,4}$/; alert(regExpPattern.test(stringToValidateArg)); } But this always returns false, any ideas why is it because of the regular expression?
