  • .NET Regex - need matching string for parsing...

    - by TomTom
    Hello, I am a regex idiot and never found a good tutorial (links welcome, as well as a pointer to an interactive VS2010 integrated editor). I need to parse strings in the following form: [a/b]:c/d a, b: double with "." as possible separator. CAN be empty c: double with "." as separator d: integer, positive I.e. valid strings are: [/]:0.25/2 [-0.5/0.5]:0.05/2 [/0.1]:0.05/2 ;) Anyone can help? Thanks

  • @Html.Label won't allow string concatination

    - by MrGrigg
    I'm building dynamic forms based on a partial view. My view inherits a model with a single property: CatalogName { get; set; }. I have tried this: @Html.Label(Model.CatalogName + "-ProductNumber", "Product Number") @Html.TextBox(Model.CatalogName + "-ProductNumber") The HTML renders like this though: <label for>Product Number</label> <input name="CatatalogName-ProductNumber" type="text" /> If I write my code like this: @Html.Label("ProductNumber-" + Model.CatalogName", "Product Number") It will render the way I expect <label for="ProductNumber-CatalogName">Product Number</label> Is this a bug with MVC? Are there any answers to why my concatenation won't work the way I want it in the label, but works fine with the TextBox?

  • Highlighting search words like Chrome with jQuery

    - by ilkin
    I have recently done a very simple highlighting with jQuery and a highlight plugin. It looks like this: $('myButton').click(function() { $('body').highlight($('#myInputText').val()); }); But I wonder how can I do the Chrome like highlighting, I mean highlight the letters whenever I type in some letter in textbox without submitting. I think maybe use a keyup event... Any ideas?

  • strict string to int[long]

    - by baskin
    Do we have a standard way of converting a char* to int (or long) in a strict way, i.e. we should get proper result only if all characters are digits and can fit in an int (or long) -- some way by using strtol etc.. ? Thus "sbc45", "4590k", " 56", "56 ", should be all invalid using that function.

  • Adding characters to string

    - by Jamza
    I am currently trying to build a very basic serial shell with my arduino. I am able to get an output from the device using Serial.read() and can get the character it has outputted, but I cannot work out how to then add that character to a longer to form the full command. I tried the logical thing but it doesn't work: char Command[]; void loop(){ if(Serial.available() > 0){ int clinput = Serial.read(); Command = Command + char(clinput); } Can anybody help? Thank You.

  • Reverse wildcard search in codeigniter

    - by Andy Platt
    I am implementing a snippet-based content management system into my current project. Snippets can be associated with a page either by exact match of the full url falling back to a wildcard match on a partial url or finally a default snippet. To implement this I have a created table of page associations with a wildcard flag, the system first checks the current url against the non-wildcard associations and if it doesn't find a match it checks against the partial url's where the wildcard flag is set. In order to achieve this I am getting all the partial url's from the database and putting them into an array then walking the array to check for a match against the current url: protected function _check_wildcard($url = NULL) { if($url) { $q = $this->db->where('wildcard' ,'Y') ->from('content') ->get(); $wildcards = $q->result_array(); foreach($wildcards AS $wildcard) { if(strpos($url,$wildcard['url']) > 0) { return $wildcard['snipppet_id']; } } } else { return NULL; } } Can anyone suggest a better way to do this - preferably one that doesn't involve having to constantly download the full list of all the wildcards each time I load a page as I am afraid that this will have a negative effect on the scalability of the system down the line?

  • Implementing search functionality with multiple optional parameters against database table.

    - by quarkX
    Hello, I would like to check if there is a preferred design pattern for implementing search functionality with multiple optional parameters against database table where the access to the database should be only via stored procedures. The targeted platform is .Net with SQL 2005, 2008 backend, but I think this is pretty generic problem. For example, we have customer table and we want to provide search functionality to the UI for different parameters, like customer Type, customer State, customer Zip, etc., and all of them are optional and can be selected in any combinations. In other words, the user can search by customerType only or by customerType, customerZIp or any other possible combinations. There are several available design approaches, but all of them have some disadvantages and I would like to ask if there is a preferred design among them or if there is another approach. Generate sql where clause sql statement dynamically in the business tier, based on the search request from the UI, and pass it to a stored procedure as parameter. Something like @Where = ‘where CustomerZip = 111111’ Inside the stored procedure generate dynamic sql statement and execute it with sp_executesql. Disadvantage: dynamic sql, sql injection Implement a stored procedure with multiple input parameters, representing the search fields from the UI, and use the following construction for selecting the records only for the requested fields in the where statement. WHERE (CustomerType = @CustomerType OR @CustomerType is null ) AND (CustomerZip = @CustomerZip OR @CustomerZip is null ) AND ………………………………………… Disadvantage: possible performance issue for the sql. 3.Implement separate stored procedure for each search parameter combinations. Disadvantage: The number of stored procedures will increase rapidly with the increase of the search parameters, repeated code.

  • Search inside dynamic array in python

    - by user2091683
    I want to implement a code that loops inside an array that its size is set by the user that means that the size isn't constant. for example: A=[1,2,3,4,5] then I want the output to be like this: [1],[2],[3],[4],[5] [1,2],[1,3],[1,4],[1,5] [2,3],[2,4],[2,5] [3,4],[3,5] [4,5] [1,2,3],[1,2,4],[1,2,5] [1,3,4],[1,3,5] and so on [1,2,3,4],[1,2,3,5] [2,3,4,5] [1,2,3,4,5] Can you help me implement this code?

  • Changing a Widget's name based on a string read in from an XML form in Qt.

    - by Nick
    I'm writing a code for a voting machine that will allow user to read in custom XML ballots and then vote on them, however in the current build I have in QtCreator, I don't see an easy way to edit buttons in my GUI directly. In the code snippet below, I assign an element to pull out the names and type of ballot being read in, but I need to append a label on the GUI as well as change buttons to the names of candidates read in. Any ideas on how to do this? while(!n.isNull()){ QDomNode x = n.firstChildElement(); QDomElement e = n.toElement(); QMessageBox::information(0, tr( "Loading Element" ), tr( "Our element is %1" ).arg(e.tagName()) ); QDomElement p = x.firstChildElement();//p finds Races QMessageBox::information(0,tr("Foo"),tr("p = %1").arg(p.text()));//finds Race and Ballot types n = n.nextSibling(); } }

  • PHP string enocding issue - Extra characters appearing

    - by ryan
    I see extra characters like â showing because of encoding issues as I found out here - HTML encoding issues - "Â" character showing up instead of "&nbsp;" I understand that if I set the browser meta encoding to UTF-8, these will not affect anything but I need to strip these extra characters from the database for other purposes. For eg. : Text: ↑ should be become Text: ? But if I run it through utf8_decode it gives me Text: ??? For every other occurrence of the â character, it converts properly to a blank space. Any help will be appreciated.
