  • Problem in Fetching Table contents when adding rows in same table

    - by jasmine
    Im trying to write a function for adding category: function addCategory() { $cname = mysql_fix_string($_POST['cname']); $kabst = mysql_fix_string($_POST['kabst']); $kselect = $_POST['kselect']; $kradio = $_POST['kradio']; $ksubmit = $_POST['ksubmit']; $id = $_POST['id']; if($ksubmit){ $query = "INSERT INTO category VALUES (' ', '{$cname}', '{$kabst}', {$kselect}, {$kradio}, ' ') "; $result = mysql_query($query); if ($result) { echo "ok"; } else{ echo $query ; } } $text .= '<div class="form"> <h2>ADD new category</h2> <form action="?page=addCategory" method="post"> <ul> <li><label>Category</label></li> <li><input name="cname" type="text" class="inp" /></li> <li><label>Description</label></li> <li><textarea name="kabst" cols="40" rows="10" class="inx"></textarea></li> <li>Published:</li> <li> <select name="kselect" class="ins"> <option value="1">Active</option> <option value="0">Passive</option> </select> </li> <li>Show in home page:</li> <li> <input type="radio" name="kradio" value="1" /> yes <input type="radio" name="kradio" value="0" /> no </li> <li>Subcategory of</li> <li> <select>'; while ($row = mysql_fetch_assoc(mysql_query("SELECT * FROM category"))){ $text .= '<option>'.$row['name'].'</option>'; } $text .= '</select> </li> <li><input name="ksubmit" type="submit" value="ekle" class="int"/></li> </ul> </form> '; return $text;} And the error: Fatal error: Maximum execution time of 30 seconds exceeded What is wrong in my function?

    I want to make a pattern route, to redirect users to login page when they are not logged in. I searched but couldn't find a solution. as always Laravel's Documentation is useless! I have this in my filter.php Route::filter('auth', function() { if (Auth::guest()) return Redirect::guest('login'); }); Route::filter('auth.basic', function() { return Auth::basic(); }); And this route in my routes.php Route::when('/*', 'auth' ); but It's not working. How can I do that?

  • How to build a C++ Dll wrapper that catches all exceptions?

    - by bart de vries
    Like the title says, we’re looking for a way to catch all exceptions from a piece of C++ code, and wrap this in a dll. This way we can shield of the application that uses this dll, from any errors occurring in this dll. However, this does not seem possible with C++ under Windows. Example: void function() { try { std::list<int>::iterator fd_it; fd_it++; } catch(...) {} } The exception that occurs is not caught by the standard C++ try/catch block, nor by any SEH translator function set by _set_se_translator(). Instead, the DLL crashes, and the program that uses the DLL is aborted. We compiled with Visual C++ 2005, with the option /SHa. Does anyone know if it’s possible in C++/Win32 to catch these kind of problems and make a rocksolid DLL wrapper?

  • jQuery: How do I stop the page being displayed until it's been processed?

    - by Alistair Christie
    I'm using jQuery to modify the style of some pages in a large set of existing Web pages. This works, but the problem I have is that, for longer pages, the page is briefly visible with the wrong styles before the javascript kicks in and transforms the page. I'm using this kind of thing (the alerts are just to emphasize the problem): $(document).ready(function(){ ... alert("at this point the page is visible unstyled"); $('body').addClass('myStyle'); alert("now page looks like I want it to"); ... } How do I prevent the browser from displaying the page until $(document).ready(function() completes?

  • Condition checking vs. Exception handling

    - by Aidas Bendoraitis
    When is exception handling more preferable than condition checking? There are many situations where I can choose using one or the other. For example, this is a summing function which uses a custom exception: # module mylibrary class WrongSummand(Exception): pass def sum_(a, b): """ returns the sum of two summands of the same type """ if type(a) != type(b): raise WrongSummand("given arguments are not of the same type") return a + b # module application using mylibrary from mylibrary import sum_, WrongSummand try: print sum_("A", 5) except WrongSummand: print "wrong arguments" And this is the same function, which avoids using exceptions # module mylibrary def sum_(a, b): """ returns the sum of two summands if they are both of the same type """ if type(a) == type(b): return a + b # module application using mylibrary from mylibrary import sum_ c = sum_("A", 5) if c is not None: print c else: print "wrong arguments" I think that using conditions is always more readable and manageable. Or am I wrong? What are the proper cases for defining APIs which raise exceptions and why?

  • Overriding Doctrine_Record (sfDoctrineRecord) instance methods in Doctrine PHP Symfony

    - by notbrain
    My background is in Propel, so I was hoping it would be a simple thing to override a magical getter in a Doctrine_Record (sfDoctrineRecord), but I'm getting either a Segfault or the override method is simply ignored in favor of the one in the superclass. https://gist.github.com/697008eaf4d7b606286a class FaqCategory extends BaseFaqCategory { public function __toString() { return $this->getCategory(); } // doesn't work // override getDisplayName to fall back to category name if getDisplayName doesn't exist public function getDisplayName() { // also tried parent::getDisplayName() but got segfault(!) if(isset($this->display_name)) { $display_name = $this->display_name; } else { $display_name = $this->category; } return $display_name; } } What is the proper Doctrine way to extend/override methods on an instance of Doctrine_Record (via sfDoctrineRecord extends Doctrine_Record)? This has to be doable...or should I be looking at the Template documentation? Thanks, Brian

  • ILClone on Windows 2000

    - by 00010000
    Does anyone know of any issues with the ILClone() function on Windows 2000? Is it fully supported? MSDN says it runs on Windows 2000 but I have a user reporting that my program will not run on Windows 2000 because of that function. EDIT: I was able to get a hold of a Win2K system and I can confirm the issue. Shell32.dll version installed is 5.0.3700.6705. The error message shown when running the program is: The procedure entry point ILClone could not be located in the dynamic link library SHELL32.DLL

  • How can I perform a web query in C# similar to the Data > Import External Data > New Web Query in Mi

    - by TNT
    I need to pull data from a table on a website. I can easily do this in VBA using the Web Query, but I need to do this in C#. I'm just having some trouble figuring out how to properly convert the code. I got something close, but it's returning HTML with the data. I just want the data. Any help would be great.

  • table cell background color change problem

    - by Mellon
    I work on another guy's code, and I try to change the table cell background color when mouse over the cell, and change back to the original background color when mouse leave. I use the following code: var bgcolor=$(".cell-el").css("background-color") $(".cell-el").hover( function(){ $(this).css("background-color", "#3c3c36")}, //mouse enter, bg-color change function(){ $(this).css("background-color", bgcolor) // mouse leave, bg-color change back }) Things are working fine, EXCEPT that when mouse first time enter the cell, the cell background color is not changed to "#3c3c36", but when mouse leave the cell after first entering and enter in the cell again, the cell's background color changed to "#3c3c36". That's the cell color never change for mouse first enter, after that, everything is working great. What's could be the cause of this problem?

  • Disable buttons on post back using jquery in .net app

    - by Chris Lively
    I have a asp.net app that I want to disable the buttons as soon as they are clicked in order to prevent multiple submissions. I'd like to use jquery for this as the site already liberally uses it anyway. What I've tried is: $(document).ready(function () { $("#aspnetForm").submit(function () { $('input[type=submit]', $(this)).attr("disabled", "disabled"); }) }); The above will disable the button, and the page submits, but the asp.net button on click handler is never called. Simply removing the above and the buttons work as normal. Is there a better way?

  • where to store helper functions?

    - by ajsie
    i've got a lot of functions i create or copy from the web. i wonder if i should store them in a file that i just include into the script or should i store each function as a static method in a class. eg. i've got a getCurrentFolder() and a isFilePhp() function. should they be stored in a file as they are or each in a class: Folder::getCurrent() File::isPhp(); how do you do? i know this is kinda a "as u want" question but it would be great with some advices/best practices thanks.

  • how to: handle exceptions, best practices

    - by b0x0rz
    need to implement a global error handling, so maybe you can help out with the following example... i have this code: public bool IsUserAuthorizedToSignIn(string userEMailAddress, string userPassword) { // get MD5 hash for use in the LINQ query string passwordSaltedHash = this.PasswordSaltedHash(userEMailAddress, userPassword); // check for email / password / validity using (UserManagementDataContext context = new UserManagementDataContext()) { var users = from u in context.Users where u.UserEMailAdresses.Any(e => e.EMailAddress == userEMailAddress) && u.UserPasswords.Any(p => p.PasswordSaltedHash == passwordSaltedHash) && u.IsActive == true select u; // true if user found return (users.Count() == 1) ? true : false; } } and the md5 as well: private string PasswordSaltedHash(string userEMailAddress, string userPassword) { MD5 hasher = MD5.Create(); byte[] data = hasher.ComputeHash(Encoding.Default.GetBytes(userPassword + userEMailAddress)); StringBuilder stringBuilder = new StringBuilder(); for (int i = 0; i < data.Length; i++) { stringBuilder.Append(data[i].ToString("x2")); } Trace.WriteLine(String.Empty); Trace.WriteLine("hash: " + stringBuilder.ToString()); return stringBuilder.ToString(); } so, how would i go about handling exceptions from these functions? they first one is called from the Default.aspx page. the second one is only called from other functions from the class library. what is the best practice? surround code INSIDE each function with try-catch surround the FUNCTION CALL with try-catch something else?? what to do if exceptions happen? in this example: this is a user sign in, so somehow even if everything fails, the user should get some meaningful info - along the lines: sign in ok (just redirect), sign in not ok (wrong user name / password), sign in not possible due to internal problems, sorry (exception happened). for the first function i am worried if there is a problem with database access. not sure if there is anything that needs to be handled in the second one. thnx for the info. how would you do it? need specific info on this (easier for me to understand), but also general info on how to handle other tasks/functions. i looked around the internet but everyone has different things to say, so unsure what to do... will go with either most votes here, or most logicaly explained answer :) thank you.

  • Why should i use EJB?

    - by Nitesh Panchal
    Hello, As we all know that EJB's in 3.1 or 3.0 are simple POJOs. You just need to give annotations here and there and it gets converted to EJB from simple class. So, now my question is why should i use EJBs at all? Can i not do without them? In .Net i created class library and got things done. I never felt the need for anything like EJB. Simple classes were enough. Then, why in Java people stress on EJB? What is difference between a simple POJO and EJB in terms of execution and memory? Further which function should i write in EJB and which should i write in simple class? Should i dump every function in EJB only? or there is some kind of strategy? Does EJB provide anything special?

  • Flex: Unexpected leakage with RemoteObject + IExternalizable?

    - by David Wolever
    I've been tinkering with IExternalizable, but I've noticed some unexpected behavior. I've got this class: public function readExternal(input:IDataInput):void { input.readObject(); input.readObject(); input.readObject(); } public function writeExternal(output:IDataOutput):void { output.writeObject("first string"); output.writeObject(424242); output.writeObject("second string"); } But when I try to serialize this class using AMF and send it to a remote server (via RemoteObject), Charles shows me that the request looks like this: But it seems wrong that my serialized object is leaking out into the rest of the request. So, what am I doing wrong? Is there some part of the documentation I've missed?

  • Cannot call scalar-valued CLR UDF from select ... from table statement

    - by Henrik B
    I have created a scalar-valued CLR UDF (user defined function). It takes a timezone id and a datetime and returns the datetime converted to that timezone. I can call it from a simple select without problems: "select dbo.udfConvert('Romance Standard Time', @datetime)" (@datetime is of course a valid datetime variable) But if I call it passing in a datetime from a table it fails: "select dbo.udfConvert('Romance Standard Time', StartTime) from sometable" (column StartTime is of course a column of type datetime) The error message is: "Cannot find either column "dbo" or the user-defined function or aggregate "dbo.udfConvert", or the name is ambiguous." This message is really for beginners that has misspelled something, but as it works in one case and not in the other, I don't think I have done any misspellings. Any ideas?

  • Actionscript base class in Flex AIR app

    - by Alan
    I'm trying to build a Flex AIR app using Flex Builder 3, which I'm just getting started with. In Flash CS4, there's a text field in the authoring environment where you can specify a class that will become the "base" class - your class inherits from Sprite and then "becomes" the Stage at runtime. Is there a a way to do the same thing with Flex/AIR? Failing that, can anyone explain how to create and use an external class? Originally I had this in TestApp.mxml: <?xml version="1.0" encoding="utf-8"?> <mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Script source="TestApp.as"/> </mx:WindowedApplication> And this in TestApp.as: package { public class TestApp { public function TestApp() { trace('Hello World'); } } } That gives the error "packages cannot be nested", so I tried taking out the package statement: public class TestApp { public function TestApp() { trace('Hello World'); } } That gives an error "classes cannot be nested", so I finally gave up and tried to take out the class altogether, figuring I'd try to start with a bunch of functions instead: function init() { trace('Hello World'); } But that gives the error "A file found in a source-path must have an externally visible definition. If a definition in the file is meant to be externally visible, please put the definition in a package". I can't win! When I put my class in a package, it says I can't do that because it would be nested. When I don't, it says it needs to be in a package so it can be seen. Does anyone know how to fix this? If I can't do the custom-class-as-base-class thing, is there a way I could just have it like: <?xml version="1.0" encoding="utf-8"?> <mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute"> <mx:Script source="TestApp.as"/> <mx:Script> var app = new TestApp(); </mx:Script> </mx:WindowedApplication> At the moment I can't import the class definition at all, so even that won't work. Thanks in advance!

  • asp.net mvc custom routes with multiple submit buttons

    - by dangerisgo
    So I have a custom route as such: routes.MapRoute( "Wizard", // Route name "Wizard/{page}", // URL with parameters new { controller = "Wizard", action = "Index" } // Parameter defaults ); and have the following on my View: <% Html.BeginForm("Continue", "Wizard"); %> <input type="submit" value="Continue" name="Continue" /> <% Html.EndForm(); %> In which I want to call this function: [AcceptVerbs(HttpVerbs.Post)] public ActionResult Continue(string Number, string Rev) { (...) } but in turn when that button is pressed always calls the postback Index rather than the one I want. If I remove the custom route, it calls my function, but what I want to be displayed in the address bar is: localhost:xxxx/Wizard/1 where the number at the end is the page (div shown) of the wizard either 1, 2, 3, or 4. So is there something I'm missing or can it not be done? Thanks.

  • Yet another php ereg fix

    - by casben79
    I have a small chunk of coding I need to take from ereg to preg_match. Here is the code. function be_file_list($d, $x) { foreach (array_diff(scandir($d), array('.', '..')) as $f) { if (is_file($d . '/' . $f) && (($x) ? ereg($x.'$',$f) : 1)) { $l[] = $f; } } return $l; } This code works as expected even if it doesn't look too pretty (source: http://www.php.net/manual/en/function.scandir.php) but as ereg is deprecated, I would really like to make it preg_match, or something like that. I have been messing with this all afternoon and the PC is about to go out the window. I would have thought that preg_match("/"$x.'$',$f"/") would have worked but no dice. Any help would be great.

  • setting value to the instance of primitive types

    I have a function which performs some operation i.e. fetches some data from database. The generic it takes is primitive type always i.e. int, char, bool, string etc. I can easily create its instance. But I can't set the value that I have fetched from database to this instance. public T PerformOperation<T>() { object instance = (T)Activator.CreateInstance(typeof(T)); object result=FetchData(); instance = (T)result; //It gives error on this statement } The function is called as: int result = PerformOperation<int>(); Is there some way of casting the object Type to any generic type which is always primitive?
