  • whats the diference between train, validation and test set, in neural networks?

    - by Daniel
    Im using this library http://pastebin.com/raw.php?i=aMtVv4RZ to implement a learning agent. I have generated the train cases, but i dont know for sure what are the validation and test sets, the teacher says: 70% should be train cases, 10% will be test cases and the rest 20% should be validation cases. Thanks. edit i have this code, for training.. but i have no ideia when to stop training.. def train(self, train, validation, N=0.3, M=0.1): # N: learning rate # M: momentum factor accuracy = list() while(True): error = 0.0 for p in train: input, target = p self.update(input) error = error + self.backPropagate(target, N, M) print "validation" total = 0 for p in validation: input, target = p output = self.update(input) total += sum([abs(target - output) for target, output in zip(target, output)]) #calculates sum of absolute diference between target and output accuracy.append(total) print min(accuracy) print sum(accuracy[-5:])/5 #if i % 100 == 0: print 'error %-14f' % error if ? < ?: break

Should mention this is ASP.NET 2.0

  • Validating String Characters as Numeric w/ Pascal (FastReport 4)

    - by user2525015
    I'm new to Pascal and FastReport. This question can probably be answered without knowledge of FastReport. Pascal is Delphi. FastReport4. I have a text box accepting an 8 character string as input. Each character should be numeric. I'm attempting to validate each character as numeric. I've tried using the val function... Procedure Val(S : String; var R: Real; Code : Integer); begin end; procedure thisinputOnChange(Sender: TfrxComponent); var S : String; error : Integer; R : Real; begin S := thisinput.lines.text; Val (S, R, error); If error > 0 then Button2.enabled := False; end; I got this code online. The explanation says that the function will return an error with a code greater than zero if the character cannot be converted to an integer. Is that explanation correct? Am I misinterpreting? Right now I am trying to set a button's enabled property to false if the validation fails. I might change that to a message. For now, I would like to get it to work by setting the button property. I'm not sure if I should be using the onChange event or another event. I'm also not sure if I need to send the input to the val function in a loop. Like I said, I'm just learning how to use this function. I am able to validate the length. This code works... procedure thisinputOnChange(Sender: TfrxComponent); begin if length(thisinput.lines.text) = 8 then Button2.enabled := True; end; Any suggestions? Should I use the val function or something else? Let me know if I need to provide more info. I might not be able to check back until later, though. Thanks for any help.

  • Regular exp to validate email in C

    - by Liju Mathew
    Hi, We need to write a email validation program in C. We are planning to use GNU Cregex.h) regular expression. The regular expression we prepared is [a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])? But the below code is failing while compiling the regex. #include <stdio.h> #include <regex.h> int main(const char *argv, int argc) { const char *reg_exp = "[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?"; int status = 1; char email[71]; regex_t preg; int rc; printf("The regex = %s\n", reg_exp); rc = regcomp(&preg, reg_exp, REG_EXTENDED|REG_NOSUB); if (rc != 0) { if (rc == REG_BADPAT || rc == REG_ECOLLATE) fprintf(stderr, "Bad Regex/Collate\n"); if (rc == REG_ECTYPE) fprintf(stderr, "Invalid Char\n"); if (rc == REG_EESCAPE) fprintf(stderr, "Trailing \\\n"); if (rc == REG_ESUBREG || rc == REG_EBRACK) fprintf(stderr, "Invalid number/[] error\n"); if (rc == REG_EPAREN || rc == REG_EBRACE) fprintf(stderr, "Paren/Bracket error\n"); if (rc == REG_BADBR || rc == REG_ERANGE) fprintf(stderr, "{} content invalid/Invalid endpoint\n"); if (rc == REG_ESPACE) fprintf(stderr, "Memory error\n"); if (rc == REG_BADRPT) fprintf(stderr, "Invalid regex\n"); fprintf(stderr, "%s: Failed to compile the regular expression:%d\n", __func__, rc); return 1; } while (status) { fgets(email, sizeof(email), stdin); status = email[0]-48; rc = regexec(&preg, email, (size_t)0, NULL, 0); if (rc == 0) { fprintf(stderr, "%s: The regular expression is a match\n", __func__); } else { fprintf(stderr, "%s: The regular expression is not a match: %d\n", __func__, rc); } } regfree(&preg); return 0; } The regex compilation is failing with the below error. The regex = [a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])? Invalid regex main: Failed to compile the regular expression:13 What is the cause of this error? Whether the regex need to be modified? Thanks, Mathew Liju

  • jQuery / javascript and nested if statements

    - by rayne
    I have a multi-lingual page where I want to display form validation error in the user's language. I use a hidden input to determine which language version the user is browsing like this: <input type="hidden" name="lang" id="lang" value="<?php echo $lang; ?>" /> The PHP side of the script works, but jQuery doesn't seem to realize which language is passed on. It displays the English error message no matter on which language site I am. Here's the code (I removed the other form fields for length): $(document).ready(function(){ $('#contact').submit(function() { $(".form_message").hide(); var emailReg = /^([\w-\.]+@([\w-]+\.)+[\w-]{2,4})?$/; var lang = $("#lang").val(); var name = $("#name").val(); var dataString = { 'lang': lang, 'name': name } if (name == '') { if (lang == 'de') { $("#posted").after('<div class="form_message"><p><span class="error">Fehler:</span> Bitte gib deinen Namen an!</p></div>'); } else { $("#posted").after('<div class="form_message"><p><span class="error">Error:</span> Please enter your name!</p></div>'); } $("#name").focus(); $("#name").addClass('req'); } else { $("#loading").show(); $("#loading").fadeIn(400).html('<img src="/img/loading.gif" />Loading...'); $.ajax({ type: "POST", url: "/contact-post.php", data: dataString, cache: false, success: function(html){ $("#loading").hide(); $("#posted").after('<div class="form_message"><p>Thank you! Your contact request has been sent.</p></div>'); $("#contact input:submit").attr("disabled", "disabled").val("Success!"); } }); }return false; }); }); The problem seems to be somewhere in the nested if statement. Does jQuery / javascript even recognize nested ifs? And if yes, why is it not working?

  • Wondering why DisplayName attribute is ignored in LabelFor on an overridden property

    - by Lasse Krantz
    Hi, today I got confused when doing a couple of <%=Html.LabelFor(m=>m.MyProperty)%> in ASP.NET MVC 2 and using the [DisplayName("Show this instead of MyProperty")] attribute from System.ComponentModel. As it turned out, when I put the attribute on an overridden property, LabelFor didn't seem to notice it. However, the [Required] attribute works fine on the overridden property, and the generated errormessage actually uses the DisplayNameAttribute. This is some trivial examplecode, the more realistic scenario is that I have a databasemodel separate from the viewmodel, but for convenience, I'd like to inherit from the databasemodel, add View-only properties and decorating the viewmodel with the attributes for the UI. public class POCOWithoutDataAnnotations { public virtual string PleaseOverrideMe { get; set; } } public class EditModel : POCOWithoutDataAnnotations { [Required] [DisplayName("This should be as label for please override me!")] public override string PleaseOverrideMe { get { return base.PleaseOverrideMe; } set { base.PleaseOverrideMe = value; } } [Required] [DisplayName("This property exists only in EditModel")] public string NonOverriddenProp { get; set; } } The strongly typed ViewPage<EditModel> contains: <div class="editor-label"> <%= Html.LabelFor(model => model.PleaseOverrideMe) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.PleaseOverrideMe) %> <%= Html.ValidationMessageFor(model => model.PleaseOverrideMe) %> </div> <div class="editor-label"> <%= Html.LabelFor(model => model.NonOverriddenProp) %> </div> <div class="editor-field"> <%= Html.TextBoxFor(model => model.NonOverriddenProp) %> <%= Html.ValidationMessageFor(model => model.NonOverriddenProp) %> </div> The labels are then displayed as "PleaseOverrideMe" (not using the DisplayNameAttribute) and "This property exists only in EditModel" (using the DisplayNameAttribute) when viewing the page. If I post with empty values, triggering the validation with this ActionMethod: [HttpPost] public ActionResult Edit(EditModel model) { if (!ModelState.IsValid) return View(model); return View("Thanks"); } the <%= Html.ValidationMessageFor(model => model.PleaseOverrideMe) %> actually uses [DisplayName("This should be as label for please override me!")] attribute, and produces the default errortext "The This should be as label for please override me! field is required." Would some friendly soul shed some light on this?

  • Validate an Xml file against a DTD with a proxy. C# 2.0

    - by Chris Dunaway
    I have looked at many examples for validating an XML file against a DTD, but have not found one that allows me to use a proxy. I have a cXml file as follows (abbreviated for display) which I wish to validate: <?xml version="1.0" encoding="utf-8"?> <!DOCTYPE cXML SYSTEM "http://xml.cxml.org/schemas/cXML/1.2.018/InvoiceDetail.dtd"> <cXML payloadID="123456" timestamp="2009-12-10T10:05:30-06:00"> <!-- content snipped --> </cXML> I am trying to create a simple C# program to validate the xml against the DTD. I have tried code such as the following but cannot figure out how to get it to use a proxy: private static bool isValid = false; static void Main(string[] args) { try { XmlTextReader r = new XmlTextReader(args[0]); XmlReaderSettings settings = new XmlReaderSettings(); XmlDocument doc = new XmlDocument(); settings.ProhibitDtd = false; settings.ValidationType = ValidationType.DTD; settings.ValidationEventHandler += new ValidationEventHandler(v_ValidationEventHandler); XmlReader validator = XmlReader.Create(r, settings); while (validator.Read()) ; validator.Close(); // Check whether the document is valid or invalid. if (isValid) Console.WriteLine("Document is valid"); else Console.WriteLine("Document is invalid"); } catch (Exception ex) { Console.WriteLine(ex.ToString()); } } static void v_ValidationEventHandler(object sender, ValidationEventArgs e) { isValid = false; Console.WriteLine("Validation event\n" + e.Message); } The exception I receive is System.Net.WebException: The remote server returned an error: (407) Proxy Authentication Required. which occurs on the line while (validator.Read()) ; I know I can validate against a DTD locally, but I don't want to change the xml DOCTYPE since that is what the final form needs to be (this app is solely for diagnostic purposes). For more information about the cXML spec, you can go to cxml.org. I appreciate any assistance. Thanks

  • DataGridView validating old value insted of new value.

    - by Scott Chamberlain
    I have a DataGridView that is bound to a DataTable, it has a column that is a double and the values need to be between 0 and 1. Here is my code private void dgvImpRDP_InfinityRDPLogin_CellValidating(object sender, DataGridViewCellValidatingEventArgs e) { if (e.ColumnIndex == dtxtPercentageOfUsersAllowed.Index) { double percentage; if(dgvImpRDP_InfinityRDPLogin[e.ColumnIndex, e.RowIndex].Value.GetType() == typeof(double)) percentage = (double)dgvImpRDP_InfinityRDPLogin[e.ColumnIndex, e.RowIndex].Value; else if (!double.TryParse(dgvImpRDP_InfinityRDPLogin[e.ColumnIndex, e.RowIndex].Value.ToString(), out percentage)) { e.Cancel = true; dgvImpRDP_InfinityRDPLogin[e.ColumnIndex, e.RowIndex].ErrorText = "The value must be between 0 and 1"; return; } if (percentage < 0 || percentage > 1) { e.Cancel = true; dgvImpRDP_InfinityRDPLogin[e.ColumnIndex, e.RowIndex].ErrorText = "The value must be between 0 and 1"; } } } However my issue when dgvImpRDP_InfinityRDPLogin_CellValidating fires dgvImpRDP_InfinityRDPLogin[e.ColumnIndex, e.RowIndex].Value will contain the old value before the edit, not the new value. For example lets say the old value was .1 and I enter 3. The above code runs when you exit the cell and dgvImpRDP_InfinityRDPLogin[e.ColumnIndex, e.RowIndex].Value will be .1 for that run, the code validates and writes 3 the data to the DataTable. I click on it a second time, try to leave, and this time it behaves like it should, it raises the error icon for the cell and prevents me from leaving. I try to enter the correct value (say .7) but the the Value will still be 3 and there is now no way out of the cell because it is locked due to the error and my validation code will never push the new value. Any recommendations would be greatly appreciated. EDIT -- New version of the code based off of Stuart's suggestion and mimicking the style the MSDN article uses. Still behaves the same. private void dgvImpRDP_InfinityRDPLogin_CellValidating(object sender, DataGridViewCellValidatingEventArgs e) { if (e.ColumnIndex == dtxtPercentageOfUsersAllowed.Index) { dgvImpRDP_InfinityRDPLogin[e.ColumnIndex, e.RowIndex].ErrorText = String.Empty; double percentage; if (!double.TryParse(dgvImpRDP_InfinityRDPLogin[e.ColumnIndex, e.RowIndex].FormattedValue.ToString(), out percentage) || percentage < 0 || percentage > 1) { e.Cancel = true; dgvImpRDP_InfinityRDPLogin[e.ColumnIndex, e.RowIndex].ErrorText = "The value must be between 0 and 1"; return; } } }

  • Rspec and Rails 3 - Problem Validating Nested Attribute Collection Size

    - by MunkiPhD
    When I create my Rspec tests, I keep getting a validation of false as opposed to true for the following tests. I've tried everything and the following is the measly code that I have now - so if it's waaaaay wrong, that's why. class Master < ActiveRecord::Base attr_accessible :name, :specific_size # Associations ---------------------- has_many :line_items accepts_nested_attributes_for :line_items, :allow_destroy => true, :reject_if => lambda { |a| a[:item_id].blank? } # Validations ----------------------- validates :name, :presence => true, :length => {:minimum => 3, :maximum => 30} validates :specific_size, :presence => true, :length => {:minimum => 4, :maximum => 30} validate :verify_items_count def verify_items_count if self.line_items.size < 2 errors.add(:base, "Not enough items to create a master") end end end And here it the items model: class LineItem < ActiveRecord::Base attr_accessible :specific_size, :other_item_type_id # Validations -------------------- validates :other_item_type_id, :presence => true validates :master_id, :presence => true validates :specific_size, :presence => true # Associations --------------------- belongs_to :other_item_type belongs_to :master end The RSpec Tests: before(:each) do @master_lines = [] @master_lines << LineItem.new(:other_item_type_id => 1, :master_id => 2, :specific_size => 1) @master_lines << LineItem.new(:other_item_type_id => 2, :master_id => 2, :specific_size => 1) @attr = {:name => "Some Master", :specific_size => "1 giga"} end it "should create a new instance given a valid name and specific size" do @master = Master.create(@attr) line_item_one = @master.line_items.build(:other_item_type_id => 1, :specific_size => 1) line_item_two = @master.line_items.build(:other_item_type_id => 2, :specific_size => 2) @master.line_items.size === 2 @master.should be_valid end it "should have at least two items to be valid" do master = Master.new(:name => "test name", :specific_size => "1 mega") master_item_one = LineItem.new(:other_item_type_id => 1, :specific_size => 2) master_item_two = LineItem.new(:other_item_type_id => 2, :specific_size => 1) master.line_items << master_item_one master.should_not be_valid master.line_items << master_item_two master.line_items.size.should === 2 master.should be_valid end I'm very new to Rspec and Rails - and I've been failing at this for the past couple of hours.

  • XML Schema: Namespace issues when importing shared elements

    - by netzwerg
    When trying to import shared definitions from a XML Schema, I can properly reference shared types, but referencing shared elements causes validation errors. This is the schema that imports the shared definitions (example.xsd): <?xml version="1.0" encoding="UTF-8"?> <xs:schema elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:shared="http://shared.com"> <xs:import namespace="http://shared.com" schemaLocation="shared.xsd"/> <xs:element name="example"> <xs:complexType> <xs:sequence> <xs:element ref="importedElement"/> <xs:element ref="importedType"/> </xs:sequence> </xs:complexType> </xs:element> <xs:element name="importedElement"> <xs:complexType> <xs:sequence> <xs:element ref="shared:fooElement"/> </xs:sequence> </xs:complexType> </xs:element> <xs:element name="importedType"> <xs:complexType> <xs:sequence> <xs:element name="bar" type="shared:barType"/> </xs:sequence> </xs:complexType> </xs:element> </xs:schema> These are the shared definitions (shared.xsd): <?xml version="1.0" encoding="UTF-8"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns="http://shared.com" targetNamespace="http://shared.com"> <xs:element name="fooElement"> <xs:simpleType> <xs:restriction base="xs:integer"/> </xs:simpleType> </xs:element> <xs:simpleType name="barType"> <xs:restriction base="xs:integer"/> </xs:simpleType> </xs:schema> Now consider this XML instance: <?xml version="1.0"?> <example xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="example.xsd"> <importedElement> <fooElement>42</fooElement> </importedElement> <importedType> <bar>42</bar> </importedType> </example> When validated, the "importedType" works perfectly fine, but the "importedElement" gives the following error: Invalid content was found starting with element 'fooElement'. One of '{"http://shared.com":fooElement}' is expected I would guess that my troubles are related to namespace issues (hence the somehow misleading "got fooElement but was expecting fooElement") -- any hints on what's wrong here?

  • ASP.NET MVC 2 "value" in DataAnnotation attribute passed is null, when incorrect date is submitted.

    - by goldenelf2
    Hello to all! This is my first question here on stack overflow. i need help on a problem i encountered during an ASP.NET MVC2 project i am currently working on. I should note that I'm relatively new to MVC design, so pls bear my ignorance. Here goes : I have a regular form on which various details about a person are shown. One of them is "Date of Birth". My view is like this <div class="form-items"> <%: Html.Label("DateOfBirth", "Date of Birth:") %> <%: Html.EditorFor(m => m.DateOfBirth) %> <%: Html.ValidationMessageFor(m => m.DateOfBirth) %> </div> I'm using an editor template i found, to show only the date correctly : <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<System.DateTime?>"%> <%= Html.TextBox("", (Model.HasValue ? Model.Value.ToShortDateString() : string.Empty))%> I used LinqToSql designer to create my model from an sql database. In order to do some validation i made a partial class Person to extend the one created by the designer (under the same namespace) : [MetadataType(typeof(IPerson))] public partial class Person : IPerson { //To create buddy class } public interface IPerson { [Required(ErrorMessage="Please enter a name")] string Name { get; set; } [Required(ErrorMessage="Please enter a surname")] string Surname { get; set; } [Birthday] DateTime? DateOfBirth { get; set; } [Email(ErrorMessage="Please enter a valid email")] string Email { get; set; } } I want to make sure that a correct date is entered. So i created a custom DataAnnotation attribute in order to validate the date : public class BirthdayAttribute : ValidationAttribute { private const string _errorMessage = "Please enter a valid date"; public BirthdayAttribute() : base(_errorMessage) { } public override bool IsValid(object value) { if (value == null) { return true; } DateTime temp; bool result = DateTime.TryParse(value.ToString(), out temp); return result; } } Well, my problem is this. Once i enter an incorrect date in the DateOfBirth field then no custom message is displayed even if use the attribute like [Birthday(ErrorMessage=".....")]. The message displayed is the one returned from the db ie "The value '32/4/1967' is not valid for DateOfBirth.". I tried to enter some break points around the code, and found out that the "value" in attribute is always null when the date is incorrect, but always gets a value if the date is in correct format. The same ( value == null) is passed also in the code generated by the designer. This thing is driving me nuts. Please can anyone help me deal with this? Also if someone can tell me where exactly is the point of entry from the view to the database. Is it related to the model binder? because i wanted to check exactly what value is passed once i press the "submit" button. Thank you.

    hi I have a custom control, (relevant code at the bottom) it consists of some text/links and a hidden textbox (rather than a hidden input). when rendered, the user via another dialog and some JS sets the value of the textbox to an integer and clicks submit on the form. i am trying to assure that the user has entered a number (via the JS) and that the textbox is not still set to its default of "0" the requiredfieldvalidator works just fine, if i dont change the value it spots it on the client and fills the validation summary on the page with the appropriate message. unfortunately when i do fill the textbox, the validator also rejests the post as the controls textbox text value is still set to "0", even though on the form it has changed. clearly i am doing something wrong.. but cant work out what it is? could someone enlighten me please, this is driving me potty if i step through the code, when the get of the mediaidtext is hit,the findcontrol finds does not the textbox, if i inspect the controls collection however i can find the textbox, but its value is still "0" it also seems that when findcontrol is called, the createchildcontrols is called again - thus resetting the value back to "0" there.. ! how can i ever assure the control realises that the textbox value has changed? many thanks code below nat [ValidationProperty("MediaIdText")] public class MediaLibraryFileControl: CompositeControl { private int mediaId = 0; public int MediaId { get { return mediaId; } set { mediaId = value; } } public string MediaIdText { get { string txt = "0"; Control ctrl = this.FindControl(this.UniqueID+ "_hidden"); try { txt = ((TextBox)ctrl).Text; MediaId = Convert.ToInt32(txt); } catch { MediaId = 0; } return txt; } } protected override void CreateChildControls() { this.Controls.Add(new LiteralControl("<span>")); this.Controls.Add(new LiteralControl("<span id=\"" + TextControlName + "\">" + getMediaDetails() + "</span>")); TextBox tb = new TextBox(); tb.Text = this.MediaId.ToString(); tb.ID = this.UniqueID + "_hidden"; tb.CssClass = "hidden"; this.Controls.Add(tb); if (Select == true) { this.Controls.Add(new LiteralControl(string.Format("&nbsp;[<a href=\"javascript:{0}(this,'{1}','{2}')\" class=\"select\">{3}</a>]", dialog, this.UniqueID, this.categoryId, "select"))); this.Controls.Add(new LiteralControl(string.Format("&nbsp;[<a href=\"javascript:{0}(this,'{1}')\" class=\"select\">{2}</a>]", clearDialog, this.ID, "clear"))); } this.Controls.Add(new LiteralControl("</span>")); } protected virtual string getMediaDetails() { //... return String.Empty; } } this is the code adding the validationcontrol the editcontrol is the instance of the control above public override Control RenderValidationControl(Control editControl) { Control ctrl = new PlaceHolder(); RequiredFieldValidator req = new RequiredFieldValidator(); req.ID = editControl.ClientID + "_validator"; req.ControlToValidate = editControl.ID; req.Display = ValidatorDisplay.None; req.InitialValue = "0"; req.EnableClientScript = false; req.ErrorMessage = "control cannot be blank"; ctrl.Controls.Add(req); return ctrl; }

  • Issue with 'selected' value within form

    - by JM4
    I currently have a form built in which after validation, if errors exist, the data stays on screen for the consumer to correct. An example of how this works for say the 'Year of Birth' is: <select name="DOB3"> <option value="">Year</option> <?php for ($i=date('Y'); $i>=1900; $i--) { echo "<option value='$i'"; if ($fields["DOB3"] == $i) echo " selected"; echo ">$i</option>"; } ?> </select> If an error is found, the year of birth value returns the year previously entered. I am able to have this work on all field with the exception of my 'State' field. I build the array and function for the drop down with the following code: <?php $states_arr = array('AL'=>"Alabama",'AK'=>"Alaska",'AZ'=>"Arizona",'AR'=>"Arkansas",'CA'=>"California",'CO'=>"Colorado",'CT'=>"Connecticut",'DE'=>"Delaware",'DC'=>"District Of Columbia",'FL'=>"Florida",'GA'=>"Georgia",'HI'=>"Hawaii",'ID'=>"Idaho",'IL'=>"Illinois", 'IN'=>"Indiana", 'IA'=>"Iowa", 'KS'=>"Kansas",'KY'=>"Kentucky",'LA'=>"Louisiana",'ME'=>"Maine",'MD'=>"Maryland", 'MA'=>"Massachusetts",'MI'=>"Michigan",'MN'=>"Minnesota",'MS'=>"Mississippi",'MO'=>"Missouri",'MT'=>"Montana",'NE'=>"Nebraska",'NV'=>"Nevada",'NH'=>"New Hampshire",'NJ'=>"New Jersey",'NM'=>"New Mexico",'NY'=>"New York",'NC'=>"North Carolina",'ND'=>"North Dakota",'OH'=>"Ohio",'OK'=>"Oklahoma", 'OR'=>"Oregon",'PA'=>"Pennsylvania",'RI'=>"Rhode Island",'SC'=>"South Carolina",'SD'=>"South Dakota",'TN'=>"Tennessee",'TX'=>"Texas",'UT'=>"Utah",'VT'=>"Vermont",'VA'=>"Virginia",'WA'=>"Washington",'WV'=>"West Virginia",'WI'=>"Wisconsin",'WY'=>"Wyoming"); function showOptionsDrop($array, $active, $echo=true){ $string = ''; foreach($array as $k => $v){ $s = ($active == $k)? ' selected="selected"' : ''; $string .= '<option value="'.$k.'"'.$s.'>'.$v.'</option>'."\n"; } if($echo) { echo $string;} else { return $string;} } ?> I then call the function from within the form using: <td><select name="State"><option value="">Choose a State</option><?php showOptionsDrop($states_arr, null, true); ?></select></td> Not sure what I'm missing but would love any assistance if somebody sees the error in my code. Thanks!

  • ANY way to consolidate this code?

    - by JM4
    I am building a PHP registration form which takes the following fields for up to 20 athletes: First Name Middle Initial Last Name Federation Number Address City State Zip DOB SSN Phone Email I am only through 7 of the fields for each fighter and my php file is very large (over 40kb). Is there ANY way to consolidate this code at all? I am also having to validate the information on each field (as I said - 20 athletes x 12 fields = 240 validations on a single page). If I can send any further code let me know! <form id="Form" action="<?php $_SERVER['PHP_SELF']; ?>" method="post" name="Form" onsubmit="return Enroll_Form_Validator(this)"> <p class="title">Your Fighters' Information</p> <p>Please complete the following fields with your <span style="color:red;"> Fighters' Information</span> to continue your enrollment.</p> <br /> <?php // if $errors is not empty, the form must have failed one or more validation // tests. Loop through each and display them on the page for the user if (!empty($errors)) { echo "<div class='error'>Please fix the following errors:\n<ul>"; foreach ($errors as $error) echo "<li>$error</li>\n"; echo "</ul></div>"; } ?> <?php if ($_SESSION['Num_Fighters'] > "0") { ?> <table class="demoTable"> <tr> <td>First Name: </td> <td><input type="text" name="F1FirstName" onkeyup="if(!this.value.match(/^([a-z]+\s?)*$/i))this.value=this.value.replace(/[^a-z ]/ig,'').replace(/\s+/g,' ')" value="<?php echo $fields['F1FirstName'];

  • ASP.NET MVC 3 - New Features

    - by imran_ku07
    Introduction:          ASP.NET MVC 3 just released by ASP.NET MVC team which includes some new features, some changes, some improvements and bug fixes. In this article, I will show you the new features of ASP.NET MVC 3. This will help you to get started using the new features of ASP.NET MVC 3. Full details of this announcement is available at Announcing release of ASP.NET MVC 3, IIS Express, SQL CE 4, Web Farm Framework, Orchard, WebMatrix.   Description:       New Razor View Engine:              Razor view engine is one of the most coolest new feature in ASP.NET MVC 3. Razor is speeding things up just a little bit more. It is much smaller and lighter in size. Also it is very easy to learn. You can say ' write less, do more '. You can get start and learn more about Razor at Introducing “Razor” – a new view engine for ASP.NET.         Granular Request Validation:             Another biggest new feature in ASP.NET MVC 3 is Granular Request Validation. Default request validator will throw an exception when he see < followed by an exclamation(like <!) or < followed by the letters a through z(like <s) or & followed by a pound sign(like &#123) as a part of querystring, posted form, headers and cookie collection. In previous versions of ASP.NET MVC, you can control request validation using ValidateInputAttriubte. In ASP.NET MVC 3 you can control request validation at Model level by annotating your model properties with a new attribute called AllowHtmlAttribute. For details see Granular Request Validation in ASP.NET MVC 3.       Sessionless Controller Support:             Sessionless Controller is another great new feature in ASP.NET MVC 3. With Sessionless Controller you can easily control your session behavior for controllers. For example, you can make your HomeController's Session as Disabled or ReadOnly, allowing concurrent request execution for single user. For details see Concurrent Requests In ASP.NET MVC and HowTo: Sessionless Controller in MVC3 – what & and why?.       Unobtrusive Ajax and  Unobtrusive Client Side Validation is Supported:             Another cool new feature in ASP.NET MVC 3 is support for Unobtrusive Ajax and Unobtrusive Client Side Validation.  This feature allows separation of responsibilities within your web application by separating your html with your script. For details see Unobtrusive Ajax in ASP.NET MVC 3 and Unobtrusive Client Validation in ASP.NET MVC 3.       Dependency Resolver:             Dependency Resolver is another great feature of ASP.NET MVC 3. It allows you to register a dependency resolver that will be used by the framework. With this approach your application will not become tightly coupled and the dependency will be injected at run time. For details see ASP.NET MVC 3 Service Location.       New Helper Methods:             ASP.NET MVC 3 includes some helper methods of ASP.NET Web Pages technology that are used for common functionality. These helper methods includes: Chart, Crypto, WebGrid, WebImage and WebMail. For details of these helper methods, please see ASP.NET MVC 3 Release Notes. For using other helper methods of ASP.NET Web Pages see Using ASP.NET Web Pages Helpers in ASP.NET MVC.       Child Action Output Caching:             ASP.NET MVC 3 also includes another feature called Child Action Output Caching. This allows you to cache only a portion of the response when you are using Html.RenderAction or Html.Action. This cache can be varied by action name, action method signature and action method parameter values. For details see this.       RemoteAttribute:             ASP.NET MVC 3 allows you to validate a form field by making a remote server call through Ajax. This makes it very easy to perform remote validation at client side and quickly give the feedback to the user. For details see How to: Implement Remote Validation in ASP.NET MVC.       CompareAttribute:             ASP.NET MVC 3 includes a new validation attribute called CompareAttribute. CompareAttribute allows you to compare the values of two different properties of a model. For details see CompareAttribute in ASP.NET MVC 3.       Miscellaneous New Features:                    ASP.NET MVC 2 includes FormValueProvider, QueryStringValueProvider, RouteDataValueProvider and HttpFileCollectionValueProvider. ASP.NET MVC 3 adds two additional value providers, ChildActionValueProvider and JsonValueProvider(JsonValueProvider is not physically exist).  ChildActionValueProvider is used when you issue a child request using Html.Action and/or Html.RenderAction methods, so that your explicit parameter values in Html.Action and/or Html.RenderAction will always take precedence over other value providers. JsonValueProvider is used to model bind JSON data. For details see Sending JSON to an ASP.NET MVC Action Method Argument.           In ASP.NET MVC 3, a new property named FileExtensions added to the VirtualPathProviderViewEngine class. This property is used when looking up a view by path (and not by name), so that only views with a file extension contained in the list specified by this new property is considered. For details see VirtualPathProviderViewEngine.FileExtensions Property .           ASP.NET MVC 3 installation package also includes the NuGet Package Manager which will be automatically installed when you install ASP.NET MVC 3. NuGet makes it easy to install and update open source libraries and tools in Visual Studio. See this for details.           In ASP.NET MVC 2, client side validation will not trigger for overridden model properties. For example, if have you a Model that contains some overridden properties then client side validation will not trigger for overridden properties in ASP.NET MVC 2 but client side validation will work for overridden properties in ASP.NET MVC 3.           Client side validation is not supported for StringLengthAttribute.MinimumLength property in ASP.NET MVC 2. In ASP.NET MVC 3 client side validation will work for StringLengthAttribute.MinimumLength property.           ASP.NET MVC 3 includes new action results like HttpUnauthorizedResult, HttpNotFoundResult and HttpStatusCodeResult.           ASP.NET MVC 3 includes some new overloads of LabelFor and LabelForModel methods. For details see LabelExtensions.LabelForModel and LabelExtensions.LabelFor.           In ASP.NET MVC 3, IControllerFactory includes a new method GetControllerSessionBehavior. This method is used to get controller's session behavior. For details see IControllerFactory.GetControllerSessionBehavior Method.           In ASP.NET MVC 3, Controller class includes a new property ViewBag which is of type dynamic. This property allows you to access ViewData Dictionary using C # 4.0 dynamic features. For details see ControllerBase.ViewBag Property.           ModelMetadata includes a property AdditionalValues which is of type Dictionary. In ASP.NET MVC 3 you can populate this property using AdditionalMetadataAttribute. For details see AdditionalMetadataAttribute Class.           In ASP.NET MVC 3 you can also use MvcScaffolding to scaffold your Views and Controller. For details see Scaffold your ASP.NET MVC 3 project with the MvcScaffolding package.           If you want to convert your application from ASP.NET MVC 2 to ASP.NET MVC 3 then there is an excellent tool that automatically converts ASP.NET MVC 2 application to ASP.NET MVC 3 application. For details see MVC 3 Project Upgrade Tool.           In ASP.NET MVC 2 DisplayAttribute is not supported but in ASP.NET MVC 3 DisplayAttribute will work properly.           ASP.NET MVC 3 also support model level validation via the new IValidatableObject interface.           ASP.NET MVC 3 includes a new helper method Html.Raw. This helper method allows you to display unencoded HTML.     Summary:          In this article I showed you the new features of ASP.NET MVC 3. This will help you a lot when you start using ASP MVC 3. I also provide you the links where you can find further details. Hopefully you will enjoy this article too.

  • jquery: validate that text field is numeric

    - by George Johnston
    I have simple issue -- I would like to check a field to see if it's numeric if it is not blank. I'm not using any additional plugins, just jQuery. My code is as follows: if($('#Field').val() != "") { if($('#Field').val().match('^(0|[1-9][0-9]*)$')) { errors+= "Field must be numeric.<br/>"; success = false; } } ...It doesn't seem to work. Where am I going wrong? Thanks, George

  • ASPNET MVC - Why is ModelState.IsValid false "The x field is required" when that field does have a v

    - by JK
    I have a model like this: public PurchaseOrder { [Required] [StringLength(15)] public virtual string OrderNumber {get;set;} // etc. } When I submit an order from the view (using $.post, not input type=submit) it goes to my controller class: public class PurchaseOrderController { public JsonResult Save(PurchaseOrder order) { // TryUpdateModel(order); // commented out since modelstate.isvalid remains false anyway if (ModelState.IsValid) { // its never valid } } } ModelState.IsValid always returns false, with the error: "The Order Number field is required." But there is a value in this field (?? why) Why would it say "value is required" when it does have a value? Have I missed something? Is it because of the $.post instead of the submit? What can I do? This is what the debugger looks like:

  • ASP.NET MVC Html.ValidationSummary(true) does not display model errors

    - by msi
    I have some problem with Html.ValidationSummary. I don't want to display property errors in ValidationSummary. And when I set Html.ValidationSummary(true) it does not display error messages from ModelState. When there is some Exception in controller action on string MembersManager.RegisterMember(member); catch section adds an error to the ModelState: ModelState.AddModelError("error", ex.Message); But ValidationSummary does not display this error message. When I set Html.ValidationSummary(false) all messages are displaying, but I don't want to display property errors. How can I fix this problem? Here is the code I'm using: Model: public class Member { [Required(ErrorMessage = "*")] [DisplayName("Login:")] public string Login { get; set; } [Required(ErrorMessage = "*")] [DataType(DataType.Password)] [DisplayName("Password:")] public string Password { get; set; } [Required(ErrorMessage = "*")] [DataType(DataType.Password)] [DisplayName("Confirm Password:")] public string ConfirmPassword { get; set; } } Controller: [HttpPost] public ActionResult Register(Member member) { try { if (!ModelState.IsValid) return View(); MembersManager.RegisterMember(member); } catch (Exception ex) { ModelState.AddModelError("error", ex.Message); return View(member); } } View: <% using (Html.BeginForm("Register", "Members", FormMethod.Post, new { enctype = "multipart/form-data" })) {%> <p> <%= Html.LabelFor(model => model.Login)%> <%= Html.TextBoxFor(model => model.Login)%> <%= Html.ValidationMessageFor(model => model.Login)%> </p> <p> <%= Html.LabelFor(model => model.Password)%> <%= Html.PasswordFor(model => model.Password)%> <%= Html.ValidationMessageFor(model => model.Password)%> </p> <p> <%= Html.LabelFor(model => model.ConfirmPassword)%> <%= Html.PasswordFor(model => model.ConfirmPassword)%> <%= Html.ValidationMessageFor(model => model.ConfirmPassword)%> </p> <div> <input type="submit" value="Create" /> </div> <%= Html.ValidationSummary(true)%> <% } %>

  • maxlength attribute of a text box from the DataAnnotations StringLength in MVC2

    - by Pervez Choudhury
    I am working on an MVC2 application and want to set the maxlength attributes of the text inputs. I have already defined the stringlength attribute on the Model object using data annotations and it is validating the length of entered strings correctly. I do not want to repeat the same setting in my views by setting the max length attribute manually when the model already has the information. Is there any way to do this? Code snippets below: From the Model: [Required, StringLength(50)] public string Address1 { get; set; } From the View: <%= Html.LabelFor(model => model.Address1) %> <%= Html.TextBoxFor(model => model.Address1, new { @class = "text long" })%> <%= Html.ValidationMessageFor(model => model.Address1) %> What I want to avoid doing is: <%= Html.TextBoxFor(model => model.Address1, new { @class = "text long", maxlength="50" })%> Is there any way to do this?

  • Bug with asp.net mvc2, collection and ValidationMessageFor ?

    - by Rafael Mueller
    I'm with a really weird bug with asp.net mvc2 (rtm) and ValidationMessageFor. The example below throws a System.Collections.Generic.KeyNotFoundException on Response.Write(Html.ValidationMessageFor(n = n[index].Name)); Any ideas why thats happening? I'm accessing the same dictionary twice before, but it only throws the error on ValidationMessageFor, any thoughts? Here's the code. public class Parent { public IList<Child> Childrens { get; set; } [Required] public string Name { get; set; } } public class Child { [Required] public string Name { get; set; } } The controller public class ParentController : Controller { public ActionResult Create() { var parent = new Parent { Name = "Parent" }; parent.Childrens = new List<Child> { new Child(), new Child(), new Child() }; return View(parent); } } The view (Create.aspx) <%@ Page Title="" Language="C#" MasterPageFile="~/Views/Shared/Site.Master" Inherits="System.Web.Mvc.ViewPage<Parent>" %> <%@ Import Namespace="BugAspNetMVC" %> <asp:Content ID="Content2" ContentPlaceHolderID="MainContent" runat="server"> <%Html.EnableClientValidation(); %> <% using (Html.BeginForm()) {%> <%=Html.LabelFor(p => p.Name)%> <%=Html.TextBoxFor(p => p.Name)%> <%=Html.ValidationMessageFor(p => p.Name)%> <%Html.RenderPartial("Childrens", Model.Childrens); %> <%} %> </asp:Content> And the partial view (Childrens.ascx) <%@ Control Language="C#" Inherits="System.Web.Mvc.ViewUserControl<IList<Child>>" %> <%@ Import Namespace="BugAspNetMVC"%> <% for (int i = 0; i < Model.Count; i++) { var index = i; Response.Write(Html.LabelFor(n => n[index].Name)); Response.Write(Html.TextBoxFor(n => n[index].Name)); Response.Write(Html.ValidationMessageFor(n => n[index].Name)); } %>
