  • How can I convert arbitrary strings to CLS-Compliant names?

    - by Brian Hinchey
    Does anyone know of an algorithm (or external library) that I could call to convert an arbitrary string (i.e. outside my control) to be CLS compliant? I am generating a dynamic RDLC (Client Report Definition) for an ASP.Net Report Viewer control and some of the field names need to be based on strings entered by the user. Unfortunately I have little control over the entry of the field names by the client (through a 3rd party CMS). But I am quite flexible around substitutions required to create the compliant string. I have a reactive hack algorithm for now along the lines of: public static string FormatForDynamicRdlc(this string s) { //We need to change this string to be CLS compliant. return s.Replace(Environment.NewLine, string.Empty) .Replace("\t", string.Empty) .Replace(",", string.Empty) .Replace("-", "_") .Replace(" ", "_"); } But I would love something more comprehensive. Any ideas? NOTE: If it is of any help, the algorithm I am using to create the dynamic RDLC is based on the BuildRDLC method found here: http://csharpshooter.blogspot.com/2007/08/revised-dynamic-rdlc-generation.html

  • Optimize conditional operators branching in C#

  • Fully custom validation error message with Rails

    - by marcgg
    Using Rails I'm trying to get an error message like "The song field can't be empty" on save. Doing the following: validates_presence_of :song_rep_xyz, :message => "can't be empty" ... only displays "Song Rep XYW can't be empty", which is not good because the title of the field is not user friendly. How can I change the title of the field itself ? I could change the actual name of the field in the database, but I have multiple "song" fields and I do need to have specific field names. I don't want to hack around rails' validation process and I feel there should be a way of fixing that.

  • WPF - How do I style a row based on a binding property value?

    - by Nick
    Hey! So I am trying to bind a collection of objects (IList<) to a WPF datagrid. I would like to make the row background a different color if the 'artist' property is null or empty. I am checking the value stored at the property on the LoadingRow datagrid event. Currently my implementation seems to style all of the rows with an empty or null 'artist' property correctly. The problem is that is also styles the rows where the property is not null or empty in some cases. So some rows are given the red background even though the rows 'artist' property is not null. Can anyone tell me why this could be?? Here is the LoadingRow event: private void trackGrid_LoadingRow(object sender, DataGridRowEventArgs e) { Track t = e.Row.DataContext as Track; if (String.IsNullOrEmpty(t.Artist)) { e.Row.Background = new System.Windows.Media.SolidColorBrush(System.Windows.Media.Color.FromArgb(255, 255, 125, 125)); } }

  • Content pulled in via jQuery AJAX is not associating with previous functions

    - by Jarsen
    I'm using the jquery .load() function to pull in data to populate a div with. The content I'm pulling in has CSS selectors that should match up with jQuery click functions I've written. However, when I load in the data, although the correct CSS selectors are there, when I click on areas that should invoke a response from jQuery, nothing happens. Do I need to do some sort of reload? Here's the code I've got for the jQuery AJAX: $(document).ready(function() { // AJAX functionality for drupal nodes $(".ajax_node").click(function() { var ajax_src = $(this).attr("href"); // we're gonna load the href // empty target div and load in content // the space in the string before the #id is necessary $("#ajax_area").empty().load(ajax_src + " #ajax_wrapper"); return false; // stops the link from following through }); // General AJAX fucntionality $(".ajax").click(function() { var ajax_src = $(this).attr("href"); $("#ajax_area").empty().load(ajax_src); return false; }); });

  • how to insert date in mysql table

    - by mithun1538
    Hello everyone, I have a mysql table called pollOfTheWeek. It has a column "pollDate" of type date. I have two questions regarding this : 1. I declared the column while creating the table as [pollDate date] What I wanted is that this column be set automatically, when the user doesnt enter any value for this column. How do i declare the column to achieve this? Assuming that I have the same declaration as above, how do I enter an empty value. I mean if the column was of type varchar, I would enter empty value as " ". But since it is of type date, I get error when I enter the value as " ". How do I enter empty value for the pollDate column?

  • ssrs: one static row matrix, multiple columns will not filter out nulls

    - by pbarton99
    Using a ssrs 2005 matrix client side. I want to list the multiple addresses of one person, hence one row, multiple columns. The Column field is =Fields!StreetName.Value. The data details field is =First(Fields!StreetPrefix.Value) & " " & First(Fields!StreetName.Value). The datasource has a row for each address; however, some rows will have nulls since the datasource is composed of outer joins. The column grouping works, but the first column is always empty, (first 2 rows of datasource are null) addresses appear only after the empty column. I want to filter out nulls on the matrix, but its like the filter is ignored. I have also tried having the dataset return an empty string for a null streetname and setting the filter to =Fields!StreetName.Value != ="" but no difference. What am I missing?

  • test cases for testing a strtok-alike function [C++]

    - by Neeraj
    Consider the following class definition: class StrToTokens { StrToTokens(const char* str, const char* delimiters = "\t\r\n"); //constructor string getNextToken(); void reset(); bool empty(); } Can someone list some good testcases to test the above class. A few I could think of are: empty string, empty delimiters, repeated delimiters, consecutive delimiters, string with only delimiters. However, the interviewer expected some more(better ones). Can you help out. Thanks.

  • ArgumentException or ArgumentNullException for string parameters?

    - by Anna Lear
    Far as best practices are concerned, which is better: public void SomeMethod(string str) { if(string.IsNullOrEmpty(str)) { throw new ArgumentException("str cannot be null or empty."); } // do other stuff } or public void SomeMethod(string str) { if(str == null) { throw new ArgumentNullException("str"); } if(str == string.Empty) { throw new ArgumentException("str cannot be empty."); } // do other stuff } The second version seems more precise, but also more cumbersome than the first. I usually go with #1, but figured I'd check if there's an argument to be made for #2.

  • MVC binding form data problem.

    - by John
    I am using an object that matches all the fields in my form. I then use the default binding to populate the object in my action, like this; public ActionResult GetDivisionData(DivisionObj FormData) My DivisionObj initializes all it's values to string.empty in the constructor. The problem is that when the binder populates the model from the posted form data, any data that is not posted is set to null in the object, eventhough I initialized the object to contain empty strings. Is there a way to change this so that unposted data will be an empty string.

  • (NOT) NULL for NVARCHAR columns

    - by Anders Abel
    Allowing NULL values on a column is normally done to allow the absense of a value to be represented. When using NVARCHAR there is aldready a possibility to have an empty string, without setting the column to NULL. In most cases I cannot see a semantical difference between an NVARCHAR with an empty string and a NULL value for such a column. Setting the column as NOT NULL saves me from having to deal with the possibility of NULL values in the code and it feels better to not have to different representations of "no value" (NULL or an empty string). Will I run into any other problems by setting my NVARCHAR columns to NOT NULL. Performance? Storage size? Anything I've overlooked on the usage of the values in the client code?

  • How to test if a user has uploaded a file ?

    - by Tristan
    Hello, on a page, i have : if (!empty($_FILES['logo']['name'])) { $dossier = 'upload/'; $fichier = basename($_FILES['logo']['name']); $taille_maxi = 100000; $taille = filesize($_FILES['logo']['tmp_name']); $extensions = array('.png', '.jpg', '.jpeg'); $extension = strrchr($_FILES['logo']['name'], '.'); //Début des vérifications de sécurité... if(!in_array($extension, $extensions)) { $erreur = 'ERROR you must upload the right type'; } if($taille>$taille_maxi) { $erreur = 'too heavy'; } if(!empty($erreur)) { ....................... } The problem is, if the users wants to edit information WITHOUT uploading a LOGO, it raises an error : 'error you must upload the right type' So, if a user didn't put anything in the inputbox in order to upload it, i don't want to enter in these conditions test. i tested : if (!empty($_FILES['logo']['name']) and if (isset($_FILES['logo']['name']) but both doesn't seems to work. Any ideas? thanks.

Please what is the magical formula ? Thanks.

  • jQuery selector after dynamically created element

    - by Bryan Williams
    I am trying to get an dynamically created element using a jQuery selector but it is returning an empty array. The first thing I am doing is grabbing an empty div: var packDiv = document.getElementById('templates'); packDiv.innerHTML = ""; then adding items to it in a loop: packDiv.innerHTML = packDiv.innerHTML + "<img id='" + thumbName + "' src='thumbs/" + thumbName + "'/>"; after the loop finishes I try to select an item using: console.log($("#"+thumbName)); and it returns the empty array. All the things I search on show to use .on but all the examples show that is to set event handlers. My question is how do I format a selector for dynamically created elements?

  • Replace strings differently depending if is enclosed in braces or not.

    - by peroyomas
    I want to replace all instances of an specific words between braces with something else, unless it is written between double braces, while it should show as is it was written with single braces without the filter. I have tried a code but only works for the first match. The rest are shown depending of the first one: $foo = 'a {bar} b {{bar}} c {bar} d'; $baz = 'Chile'; preg_match_all( '/(\{?)\{(tin)\}(\}?)/i', $foo, $matches, PREG_SET_ORDER ); if ( !empty($matches) ) { foreach ( (array) $matches as $match ) { if( empty($match[1]) && empty($match[3])) { $tull = str_replace( $match[0], $baz, $foo ); } else { $tull = str_replace( $match[0], substr($match[0], 1, -1), $foo ) ; } } } echo $tull;

  • Passing NULL values into mysql Stored procedure

    - by McNabbToSkins
    I am trying to pass a few NULL values to a stroed procedure but PHP always retains the varaibles to be empty strings '' and not NULL. My DB insert function looks like this. (I am using a Framework and ADODB so if it looks weird thats why). function insert_emp($f_name, $last_name, $dob) { if(!isset($dob)){ $dob = NULL; } $this->DB->setConnection("CALL insert_emp('$f_name', '$l_name', '$dob')"); } I have ensured that $dob is being passed an empty string ''. But for some reason when it calls the stored proc it is not changed to NULL. dob is a datetime field and mysql complains that you can not enter an empty string as a DATETIME. If I hard code the insert such as this $this->DB->setConnection("CALL insert_emp('Test1', 'Test2', 'NULL')"); it will work. Thanks for the help.

  • Setting cookie in LiftFilter

    - by Gero
    Hi, How do I set a cookie in a LiftFilter.doFilter method? I tried to set the cookie as follows (stripped some code): class AuthenticationFilter extends LiftFilter { override def doFilter(request: ServletRequest, response: ServletResponse , chain: FilterChain) { val cookie = new HTTPCookie("SomeCookie", Full("" + System.nanoTime), Empty, Full("/authentication"), Full(60 * 60 * 24 * 14), Empty, Empty) cookie.setPath("/somePath") S.addCookie(cookie) val httpResp = response.asInstanceOf[HttpServletResponse] httpResp.sendRedirect("/some/page.html") } } However, when I check the browsers cookie, no cookie is set (apart from JSESSIONID), and I know the doFilter method is being executed because of logging messages and the fact that the browser is redirected to /some/page.html. I'm using Scala 2.8, Lift 2.1-SNAPSHOT and the app is running is GAE (1.3.6, only tested on dev_appserver so far). Any ideas? Thanks, Gero

    - by Angela
    I have the following in the view: <% unless contact_email.statuses.empty?%> (<%= contact_email.statuses.find(:last).status%>) <% end %> contact_email is an instance of a specific model. Could I do something like this? class ContactEmail < ActiveRecord::Base attr_accessible :contact_id, :email_id, :status, :subject, :body, :date_created, :date_sent def status unless contact_email.statuses.empty? contact_email.statuses.find(:last).status end end end is there a better way to do this? is there a way to use the || operator for a default if empty? Basically, I would like to be able to do the following in the View: <%= contact_email.status = IF there is a value, then display it, if not, show nothing.

  • C++ std::equal -- rationale behind not testing for the 2 ranges having equal size?

    - by ShaChris23
    I just wrote some code to test the behavior of std::equal, and came away surprised: int main() { try { std::list<int> lst1; std::list<int> lst2; if(!std::equal(lst1.begin(), lst1.end(), lst2.begin())) throw std::logic_error("Error: 2 empty lists should always be equal"); lst2.push_back(5); if(std::equal(lst1.begin(), lst1.end(), lst2.begin())) throw std::logic_error("Error: comparing 2 lists where one is not empty should not be equal"); } catch(std::exception& e) { std::cerr << e.what(); } } The output (a surprise to me): Error: comparing 2 lists where one is not empty should not be equal Observation: why is it the std::equal does not first check if the 2 containers have the same size() ? Was there a legitimate reason?
