  • minLength data validation is not working with Auth component for CakePHP

    - by grokker
    Let's say I have a user registration and I'm using the Auth component (/user/register is allowed of course). The problem is if I need to set a minLength validation rule in the model, it doesn't work since the Auth component hashes the password therefore it's always more than my minlength password and it passes even if it's blank. How do I fix this issue? Thanks in advance!

  • Shortest distance between two line segments

    - by Frank
    I need a function to find the shortest distance between two line segments. A line segment is defined by two endpoints. So for example one of my line segments (AB) would be defined by the two points A (x1,y1) and B (x2,y2) and the other (CD) would be defined by the two points C (x1,y1) and D (x2,y2). Feel free to write the solution in any language you want and I can translate it into javascript. Please keep in mind my geometry skills are pretty rusty. I have already seen http://stochastix.wordpress.com/2008/12/28/distance-between-two-lines/ and I am not sure how to translate this into a function. Thank you so much for help.

  • Detect whether or not a specific attribute was valid on the model

    - by Sir Code-A-Lot
    Having created my own validation attribute deriving from System.ComponentModel.DataAnnotations.ValidationAttribute, I wish to be able to detect from my controller, whether or not that specific attribute was valid on the model. My setup: public class MyModel { [Required] [CustomValidation] [SomeOtherValidation] public string SomeProperty { get; set; } } public class CustomValidationAttribute : ValidationAttribute { public override bool IsValid(object value) { // Custom validation logic here } } Now, how do I detect from the controller whether validation of CustomValidationAttribute succeeded or not? I have been looking at the Exception property of ModelError in the ModelState, but I have no way of adding a custom exception to it from my CustomValidationAttribute. Right now I have resorted to checking for a specific error message in the ModelState: public ActionResult PostModel(MyModel model) { if(ModelState.Where(i => i.Value.Errors.Where((e => e.ErrorMessage == CustomValidationAttribute.SharedMessage)).Any()).Any()) DoSomeCustomStuff(); // The rest of the action here } And changed my CustomValidationAttribute to: public class CustomValidationAttribute : ValidationAttribute { public static string SharedMessage = "CustomValidationAttribute error"; public override bool IsValid(object value) { ErrorMessage = SharedMessage; // Custom validation logic here } } I don't like relying on string matching, and this way the ErrorMessage property is kind of misused. What are my options?

  • 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.

  • How do I capture keystrokes on the web?

    - by Sean
    Using PHP, JS, or HTML (or something similar) how would I capture keystokes? Such as if the user presses ctrl+f or maybe even just f, a certain function will happen. ++++++++++++++++++++++++EDIT+++++++++++++++++++ Ok, so is this correct, because I can't get it to work. And I apologize for my n00bness is this is an easy question, new to jQuery and still learning more and more about JS. <script> var element = document.getElementById('capture'); element.onkeypress = function(e) { var ev = e || event; if(ev.keyCode == 70) { alert("hello"); } } </script> <div id="capture"> Hello, Testing 123 </div> ++++++++++++++++EDIT++++++++++++++++++ Here is everything, but I can't get it to work: <link rel="icon" href="favicon.ico" type="image/x-icon"> <style> * { margin: 0px } div { height: 250px; width: 630px; overflow: hidden; vertical-align: top; position: relative; background-color: #999; } iframe { position: absolute; left: -50px; top: -130px; } </style> <script> document.getElementsByTagName('body')[0].onkeyup = function(e) { var ev = e || event; if(ev.keyCode == 70 && ev.ctrlKey) { //control+f alert("hello"); } } </script> <div id="capture"> Hello, Testing 123<!--<iframe src="http://www.pandora.com/" scrolling="no" width="1000" height="515"frameborder="0"></iframe>--> </div>

    - by Hamish Grubijan
    Write a program that prints the numbers from 1 to 100. But for multiples of three print "Fizz" instead of the number and for the multiples of five print "Buzz". For numbers which are multiples of both three and five print "FizzBuzz". Woman said use any common language. Please make it short and test it. My screen is small. Thanks. P.S. I have test anxiety particularly after talking to people in suits. I also stayed up all night studying Java codes.

  • What's the right way to handle "One, Both, or None" logic?

    - by Stephen
    I have a logic situation that is best described as two "Teams" trying to win a task. The outcome of this task could be a single winner, a tie (draw), or no winner (stalemate). Currently, I'm using a nested if/else statement like so: // using PHP, but the concept seems language agnostic. if ($team_a->win()) { if ($team_b->win()) { // this is a draw } else { // team_a is the winner } } else { if ($team_b->win()) { // team_b is the winner } else { // This is a stalemate, no winner. } } This seems rather spaghetti-like and repetitive. Is there a more logical, DRY pattern I could use?

  • How to restrict special symbols like % in textbox in wpf?

    - by Vamsy
    I would like to develop a textbox which restricts special symbols like %. I used textbox's keydown event to restrict '%' . I already used the code as if(Keyboard.Modifiers == ModifierKeys.Shift && e.key == key.D5) { e.handle=true; return; } when i implement this in mvvm architecture, I got problem with the dependency property that recognizes only shift as one key and D5 as another when I converted systemkey into string format. How can I recognize % symbol?

  • User controlled html title tags

    - by zaf
    What are the best practices for allowing a user to maintain the html title tags of all the major pages of his/her site? One way could be to allow the mapping of URLs to some text. For example, we have an app with the following (most complex) url format: http://lang.example.com/searchpage.zaf?a=foo&b=bar&c=RANDOM There are several parts to this: Language sub domain Search page Static parameter 'a' (user may want this in the title) Dynamic and relevant parameter 'b' (user may want this in the title) Dynamic parameter 'c' which can be ignored Never done this before, so I'm asking how you would tackle this!

  • Handling of data truncation (short reads/writes) in FUSE

    - by Vi
    I expect any good program should do all their reads and writes in a loop until all data written/read without relying that write will write everything (even with regular files). Am I right? Implemented simple FUSE filesystem which only allows reading and writing with small buffers, very often returning that it is written less bytes that in a buffer (using -o direct_io). Some programs work, some not (notably mountlo). Are them buggy or programs should not expect truncated writes and reads from the regular files? In general, are seekable file descriptors expected to truncate data like sockets and pipes?

  • Reference table values in a war against magic numbers

    - by Alex N.
    This question bugged me for years now and can't seem to find good solution still. I working in PHP and Java but it sounds like this maybe language-agnostic :) Say we have a standard status reference table that holds status ids for some kind of entity. Further let's assume the table will have just 5 values, and will remain like this for a long time, maybe edited occasionally with addition of a new status. When you fetch a row and need to see what status it is you have 2 options(as I see it at least) - put it straight ID values(magic numbers that is) or use a named constant. Latter seem much cleaner, the question though is where those named constants should leave? In a model class? In a class that uses this particular constant? Somewhere else?

  • Any chances to imitate times() Ruby method in C#?

    - by Alexander Prokofyev
    Every time I need to do something N times inside an algorithm using C# I write this code for (int i = 0; i < N; i++) { ... } Studying Ruby I have learned about method times() which can be used with the same semantics like this N.times do ... end Code fragment in C# looks more complex and we should declare useless variable i. I tried to write extension method which returns IEnumerable, but I am not satisfied with the result because again I have to declare a cycle variable i. public static class IntExtender { public static IEnumerable Times(this int times) { for (int i = 0; i < times; i++) yield return true; } } ... foreach (var i in 5.Times()) { ... } Is it possible using some new C# 3.0 language features to make N times cycle more elegant?

  • Is MS Access still the most efficient RAD tool for small-scale custom apps?

    - by FastAl
    Of the many other development tools I've used, nothing holds a candle to the 'Functionality to Development Effort' ratio of MS Access. The reason I am asking is that I have been out of the language selection process for a few years, working on a large .Net system, and am only anecdotally familiar with the latest development tools outside the .Net world. I'm well aware of the limitations of Access, but for a limited concurrency (usually only 1 user at a time), small business, custom app, has anybody found a comparable end-to-end solution or combination that comes close? It doesn't have to be free, open source, or even Windows based. It just has to allow the same speed of development and maintenance, and maybe even provide some additional amenities like seamless autointegration with a server-based DB Engine (like Access does with its own 'Jet' dbms), better web support, and a file format more compatible with source control. I don't want to miss out on anything. Please share your development experience with your suggestions. Thanks.

  • How do I check if selected value of the ListBox is not selected in C#?

    - by Sahat
    This code will display the selected value from the listbox. E.g. if I sellect Item 1 I will get the following output: You have selected Item 1. Label1.Text = "You have selected " + DropDownList1.SelectedValue + "<br />"; But if I don't select anything and click on Submit button, I will get: You have selected What would I need to make it display "You have not selected anything. Please select at least 1 item." UPDATE: I am using ASP.NET WebForms.

  • Java me : Can we retrieve bluetooth address of connected device from an open slave connection ?

    - by Rohit
    Here is a typical sequence of events that occur : Host device opens a service ( Host device accepts and opens all incoming connections) A remote device connects to host device. Now, we have a slave connection open at host device. At host device, I want to know the bluetooth address of remote device. I can always pass it as data from remote to host device, but can I extract it from connection object somehow without any data transfer? Thanks in advance...

  • PHP: File exists and is in a certain sub-directory

I know I can use file_exists to check that it exists, but I'm not sure how I should make sure that the file is in a certain sub-directory...

  • Why did the C# designers attach three different meanings to the 'using' keyword?

    - by gWiz
    The using keyword has three disparate meanings: type/namespace aliasing namespace import syntactic sugar for ensuring Dispose is called The documentation calls the first two definitions directives (which I'm guessing means they are preprocessing in nature), while the last is a statement. Regardless of the fact that they are distinguished by their syntaxes, why would the language developers complicate the semantics of the keyword by attaching three different meanings to it? For example, (disclaimer: off the top of my head, there may certainly be better examples) why not add keywords like alias and import? Technical, theoretical, or historical reasons? Keyword quota? ;-) Contrived sample: import System.Timers; alias LiteTimer=System.Threading.Timer; alias WinForms=System.Windows.Forms; public class Sample { public void Action { var elapsed = false; using(var t = new LiteTimer.Timer(_ => elapsed = true) { while (!elapsed) CallSomeFinickyApi(); } } } "Using" is such a vague word.
