  • Adding characters to string (input field)

    - by Zaps
    Hi, I have a text box where the value the result of a calculation carried out in jQuery. What I would like to do, using jQuery, is to display brackets around the number in the text box if the number is negative. The number may be used again later so I would then have to remove the brackets so further calculations could be carried out. Any ideas as to how I could implement this? Thanks Zaps

  • 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.

  • 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.

  • Detect some conflictive characters in a string with javascript

    - by FranQ
    Hello. I have a file input in a form that uploads a mp3 file, but I´d like to detect conflictive characters to my system in the filename, like ! @ or any other. All codes I´ve found replace these characters, but I just want to detect them to alert the user. I think it will be easy with regular expressions, but I dont know about them. I´m using jquery/javascript. Thanks in advance for your help Edit to improve my problem description: I´m working in a CodeIgniter application that allows user to upload mp3 files to the server. I use jQuery to manage client side forms. The CI upload class converts spaces in the file name to underscores and everything works. But testing the application I uploaded a mp3 file with a (!) in the name, and I got troubles with it. I just want to insert a javascript conditional before the file is uploaded to evaluate if the user´s filename contains a (!) (or any other I´d like to add later) to ask for the file to be renamed if it does.

  • Normalized class design and code first

    - by dc7a9163d9
    There are the following two classes. public class Employee { int EmployeeId { get; set; } public string FirstName { get; set; } public string LastName { get; set; } public string Street { get; set; } public string Street2 { get; set; } public string City { get; set; } public string State { get; set; } public string Zip { get; set; } } public class Company { int CompanyId { get; set; } public string Name { get; set; } public string Street { get; set; } public string Street2 { get; set; } public string City { get; set; } public string State { get; set; } public string Zip { get; set; } } In a DDD seminar, the speaker said the better design should be, class PersonName { public string FirstName { get; set; } public string LastName { get; set; } } class Address { public string Street { get; set; } public string Street2 { get; set; } public string City { get; set; } public string State { get; set; } public string Zip { get; set; } } public class Employee { int EmployeeId { get; set; } public PersonName Name { get; set; } [ForeignKey("EmployerAddress")] public int EmployerAddressId { get; set; } public virtual Address EmployerAddress { get; set; } } public class Company { int CompanyId { get; set; } public string Name { get; set; } [ForeignKey("CompanyAddress")] public int CompanyAddressId { get; set; } public virtual Address CompanyAddress { get; set; } } Is it the optimized design? How the code first generate the PersonName table and link it to Employee?

  • C#: Converting string to namespace

    - by Am
    Hi, I have an interface named IHarvester. There are 3 implementations of that interface, each under their own namespace: Google Yahoo Bing A HarvesterManager uses the given harvester. It knows the interface and all 3 implementations. I want some way of letting the class user say in which harvester it wants to use. And in the code select that implementation, without a switch-case implementation. Can reflection save my day? Here is the code bits: // repeat for each harvester namespace Harvester.Google { public abstract class Fetcher : BaseHarvester, IInfoHarvester {...} } public enum HarvestingSource { Google, Yahoo, Bing, } class HarvesterManager { public HarvestingSource PreferedSource {get;set;} public HarvestSomthing() { switch (PreferedSource) .... // awful... } } Thanks.

    Just using it as a method parameter is fine but what about an easy way to use it in strings?

Does it have to be some monstrosity of a macro?

    - by xintron
    I've got the following function that manipulates an element according to the data being sent (an object). function manipulateElem (elem, data) { for (var key in data) { elem[key] = data[key]; }; } manipulateElem(document.getElementById('test'), {'href': '/home/', 'style.color': '#000000'}); As you can imagine, the later (style.color) doesn't work. How would one solve this the best way?

  • PHP MySQL query string

    - by user1174762
    I am newer to PHP and MySQL and I am having trouble understanding join. I think, for me, the problem lies with actually understanding the logic of the query. What I am trying to do Is select all of the status updates from a table named "post", but only ones from users I am "following", and then display them In order by date. So, I have two databases which are set up like so: posts |post_id|user_id|post_body|date_upload| | 1 | 4 | hey. | 01/2/2012 | follows |relation_id|user_id|followee_id| | 1 | 4 | 2 | Could someone please explain how I should syntactically and Logically set this up? Thank you!
