• asp.net mvc getting id of button clicked

  - by mazhar kaunain baig

  <div id="4591" > <input type="text" id="Title1" name="Title1" value="a" /> <input type="submit" name="button" value="Save" /> </div> <div id="4592" > <input type="text" id="Title2" name="Title2" value="a" /> <input type="submit" name="button" value="Save" /> </div> <div id="4593" > <input type="text" id="Title3" name="Title3" value="a" /> <input type="submit" name="button" value="Save" /> </div> This is the copy paste version of the html source generated by the browser which is making it clear that i am generating the dynamic fields on the page. name in the textbox is the field in the database. After pressing the one of the save buttons how would i send the particular textbox name and value to the controller action to be updated.

• WP7 - listbox Binding

  - by Jeff V

  I have an ObservableCollection that I want to bind to my listbox... lbRosterList.ItemsSource = App.ViewModel.rosterItemsCollection; However, in that collection I have another collection within it: [DataMember] public ObservableCollection<PersonDetail> ContactInfo { get { return _ContactInfo; } set { if (value != _ContactInfo) { _ContactInfo = value; NotifyPropertyChanged("ContactInfo"); } } } PersonDetail contains 2 properties: name and e-mail I would like the listbox to have those values for each item in rosterItemsCollection RosterId = 0; RosterName = "test"; ContactInfo.name = "Art"; ContactInfo.email = "[email protected]"; RosterId = 0; RosterName = "test" ContactInfo.name = "bob"; ContactInfo.email = "[email protected]"; RosterId = 1; RosterName = "test1" ContactInfo.name = "chris"; ContactInfo.email = "[email protected]"; RosterId = 1; RosterName = "test1" ContactInfo.name = "Sam"; ContactInfo.email = "[email protected]"; I would like that listboxes to display the ContactInfo information. I hope this makes sense... My XAML that I've tried with little success: <listbox x:Name="lbRosterList" ItemsSource="rosterItemCollection"> <textblock x:name="itemText" text="{Binding Path=name}"/> What am I doing incorrectly?

• Why null reference exception in SetMolePublicInstance?

  - by OldGrantonian

  I get a "null reference" exception in the following line: MoleRuntime.SetMolePublicInstance(stub, receiverType, objReceiver, name, null); The program builds and compiles correctly. There are no complaints about any of the parameters to the method. Here's the specification of SetMolePublicInstance, from the object browser: SetMolePublicInstance(System.Delegate _stub, System.Type receiverType, object _receiver, string name, params System.Type[] parameterTypes) Here are the parameter values for "Locals": + stub {Method = {System.String <StaticMethodUnitTestWithDeq>b__0()}} System.Func<string> + receiverType {Name = "OrigValue" FullName = "OrigValueP.OrigValue"} System.Type {System.RuntimeType} objReceiver {OrigValueP.OrigValue} object {OrigValueP.OrigValue} name "TestString" string parameterTypes null object[] I know that TestString() takes no parameters and returns string, so as a starter to try to get things working, I specified "null" for the final parameter to SetMolePublicInstance. As already mentioned, this compiles OK. Here's the stack trace: Unhandled Exception: System.NullReferenceException: Object reference not set to an instance of an object. at Microsoft.ExtendedReflection.Collections.Indexable.ConvertAllToArray[TInput,TOutput](TInput[] array, Converter`2 converter) at Microsoft.Moles.Framework.Moles.MoleRuntime.SetMole(Delegate _stub, Type receiverType, Object _receiver, String name, MoleBindingFlags flags, Type[] parameterTypes) at Microsoft.Moles.Framework.Moles.MoleRuntime.SetMolePublicInstance(Delegate _stub, Type receiverType, Object _receiver, String name, Type[] parameterTypes) at DeqP.Deq.Replace[T](Func`1 stub, Type receiverType, Object objReceiver, String name) in C:\0VisProjects\DecP_04\DecP\DeqC.cs:line 38 at DeqPTest.DecCTest.StaticMethodUnitTestWithDeq() in C:\0VisProjects\DecP_04\DecPTest\DeqCTest.cs:line 28 at Starter.Start.Main(String[] args) in C:\0VisProjects\DecP_04\Starter\Starter.cs:line 14 Press any key to continue . . . To avoid the null parameter, I changed the final "null" to "parameterTypes" as in the following line: MoleRuntime.SetMolePublicInstance(stub, receiverType, objReceiver, name, parameterTypes); I then tried each of the following (before the line): int[] parameterTypes = null; // if this is null, I don't think the type will matter int[] parameterTypes = new int[0]; object[] parameterTypes = new object[0]; // this would allow for various parameter types All three attempts produce a red squiggly line under the entire line for SetMolePublicInstance Mouseover showed the following message: The best overloaded method match for 'Microsoft.Moles.Framework.Moles.MoleRuntime.SetMolePublicInstance(System.Delegate, System.Type, object, string, params System.Type[])' has some invalid arguments. I'm assuming that the first four arguments are OK, and that the problem is with the params array.

• PHP contact form, am I doing it wrong?

  - by decimal

  I'm learning PHP and I'm trying to write a simple email script. I have a function (checkEmpty) to check if all the forms are filled in and if the email adress is valid (isEmailValid). I'm not sure how to return true checkEmpty funciton. Here's my code: When the submit button is clicked: if (isset($_POST['submit'])) { //INSERT FORM VALUES INTO AN ARRAY $field = array ('name' => $_POST['name'], 'email' => $_POST['email'], 'message' => $_POST['message']); //CONVERT ARRAY KEYS TO VARIABLE NAMES extract ($field); checkEmpty($name, $email, $message); function checkEmpty($name, $email, $message) { global $name_error; global $mail_error; global $message_error; //CHECK IF NAME FIELD IS EMPTY if (isset($name) === true && empty($name) === true) { $name_error = "<span class='error_text'>* Please enter your name</span>"; } //CHECK IF EMAIL IS EMPTY if (isset($email) === true && empty($email) === true) { $mail_error = "<span class='error_text'>* Please enter your email address</span>"; //AND IF IT ISN'T EMPTY CHECK IF IT IS A VALID ONE } elseif (!isValidEmail($email)) { $mail_error = "<span class='error_text'> * Please enter a valid email</span>"; } //CHECK IF MESSAGE IS EMPTY if (isset($message) === true && empty($message) === true) { $message_error = "<span class='error_text'>* Please enter your message</span>"; } } // This function tests whether the email address is valid function isValidEmail($email){ $pattern = "^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$"; if (eregi($pattern, $email)) { return true; } else { return false; } } I know I shouldn't be using globals in the function, I don't know an alternative. The error messages are display beside each form element.

• one-to-many with criteria question

  - by brnzn

  enter code hereI want to apply restrictions on the list of items, so only items from a given dates will be retrieved. Here are my mappings: <class name="MyClass" table="MyTable" mutable="false" > <cache usage="read-only"/> <id name="myId" column="myId" type="integer"/> <property name="myProp" type="string" column="prop"/> <list name="items" inverse="true" cascade="none"> <key column="myId"/> <list-index column="itemVersion"/> <one-to-many class="Item"/> </list> </class> <class name="Item" table="Items" mutable="false" > <cache usage="read-only"/> <id name="myId" column="myId" type="integer"/> <property name="itemVersion" type="string" column="version"/> <property name="startDate" type="date" column="startDate"/> </class> I tried this code: Criteria crit = session.createCriteria(MyClass.class); crit.add( Restrictions.eq("myId", new Integer(1))); crit = crit.createCriteria("items").add( Restrictions.le("startDate", new Date()) ); which result the following quires: select ... from MyTable this_ inner join Items items1_ on this_.myId=items1_.myId where this_.myId=? and items1_.startDate<=? followed by select ... from Items items0_ where items0_.myId=? But what I need is something like: select ... from MyTable this_ where this_.myId=? followed by select ... from Items items0_ where items0_.myId=? and items0_.startDate<=? Any idea how I can apply a criteria on the list of items?

  - by angela

  I have a class symbol_table that has a vector of objects of another class row_st.also I have an enter method where inserts objects of row_st with a passed name into the vector of desired symbol_table.but when I call the enter to enter objects with name : a;b;c;Iwill get the following result: a,b,c;b,c;c.the first element of vector gets the name of all the entered objects. and the second element also gets the name of the later entries. class row_st { public: char* name; type_u type;//int:0,flaot:1;char:2,bool:3,array: int offset; symbol_table *next; symbol_table *current; }; class symbol_table { public: vector <row_st *> row; int type; int header; int starting_stmt; int index; int i; symbol_table *previous; symbol_table(){ header=0; previous=0; index=0;i=0;starting_stmt=0;} }; and here it is the enter method: int enter(symbol_table *table,char* name,type_u type){ row_st *t=new row_st; t->name=name; t->type=type; t->offset=table->index; t->current=table; table->index++; t->next=0; table->row.push_back(t); table->header +=1; return table->row.size()-1; } the push_backed elements all points to the same address.the new call makes the same row_st every time it is called.what should I do?

• SQL: find entries in 1:n relation that don't comply with condition spanning multiple rows

  - by milianw

  I'm trying to optimize SQL queries in Akonadi and came across the following problem that is apparently not easy to solve with SQL, at least for me: Assume the following table structure (should work in SQLite, PostgreSQL, MySQL): CREATE TABLE a ( a_id INT PRIMARY KEY ); INSERT INTO a (a_id) VALUES (1), (2), (3), (4); CREATE TABLE b ( b_id INT PRIMARY KEY, a_id INT, name VARCHAR(255) NOT NULL ); INSERT INTO b (b_id, a_id, name) VALUES (1, 1, 'foo'), (2, 1, 'bar'), (3, 1, 'asdf'), (4, 2, 'foo'), (5, 2, 'bar'), (6, 3, 'foo'); Now my problem is to find entries in a that are missing name entries in table b. E.g. I need to make sure each entry in a has at least the name entries "foo" and "bar" in table b. Hence the query should return something similar to: a_id = 3 is missing name "bar" a_id = 4 is missing name "foo" and "bar" Since both tables are potentially huge in Akonadi, performance is of utmost importance. One solution in MySQL would be: SELECT a.a_id, CONCAT('|', GROUP_CONCAT(name ORDER BY NAME ASC SEPARATOR '|'), '|') as names FROM a LEFT JOIN b USING( a_id ) GROUP BY a.a_id HAVING names IS NULL OR names NOT LIKE '%|bar|foo|%'; I have yet to measure the performance tomorrow, but severly doubt it's any fast for tens of thousand of entries in a and thrice as many in b. Furthermore we want to support SQLite and PostgreSQL where to my knowledge the GROUP_CONCAT function is not available. Thanks, good night.

• problem calculating the position using php

  - by LiveEn

  I have a function below which gets name from a site. Below is the partial code, not complete. The values are passed thru a for loop using php. function funct($$name,$page) { $url="http://testserver.com/client?list=$name&page=$page"; $ch=curl_init(); curl_setopt($ch,CURLOPT_URL,url); $result=curl_exec($ch); $dom = new DOMDocument(); @$dom->loadHTML($result); $xpath=new DOMXPath($dom); $elements = $xpath->evaluate("//div"); foreach ($elements as $element) { $name = $element->getElementsByTagName("name")->item(0)->nodeValue; $position=$position +1; echo $name.$position; } } The code works fine but when i get a name i need to add a position and for each name it will be incremented by 1 to make it contentious. But when the values for the pages are passed, for an example when i move from page 1 to page 2. the count starts again from first, next page... same problem. How can i make it continues on every page?

• Rails 3 MySQL 2 reports an error in what looks to be valid SQL syntax

  - by John Judd

  I am trying to use the following bit of code to help in seeding my database. I need to add data continually over development and do not want to have to completely reseed data every time I add something new to the seeds.rb file. So I added the following function to insert the data if it doesn't already exist. def AddSetting(group, name, value, desc) Admin::Setting.create({group: group, name: name, value: value, description: desc}) unless Admin::Setting.find_by_sql("SELECT * FROM admin_settings WHERE group = '#{group}' AND name = '#{name}';").exists? end AddSetting('google', 'analytics_id', '', 'The ID of your Google Analytics account.') AddSetting('general', 'page_title', '', '') AddSetting('general', 'tag_line', '', '') This function is included in the db/seeds.rb file. Is this the right way to do this? However I am getting the following error when I try to run it through rake. rake aborted! Mysql2::Error: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'group = 'google' AND name = 'analytics_id'' at line 1: SELECT * FROM admin_settings WHERE group = 'google' AND name = 'analytics_id'; Tasks: TOP => db:seed (See full trace by running task with --trace) Process finished with exit code 1 What is confusing me is that I am generating correct SQL as far as I can tell. In fact my code generates the SQL and I pass that to the find_by_sql function for the model, Rails itself can't be changing the SQL, or is it? SELECT * FROM admin_settings WHERE group = 'google' AND name = 'analytics_id'; I've written a lot of SQL over the years and I've looked through similar questions here. Maybe I've missed something, but I cannot see it.

• Exclude notes based on attribute wildcard in XSL node selection

  - by C A

  Using cruisecontrol for continuous integration, I have some annoyances with Weblogic Ant tasks and how they think that server debug information are warnings rather than debug, so are shown in my build report emails. The XML output from cruise is similar to: <cruisecontrol> <build> <target name="compile-xxx"> <task name="xxx" /> </target> <target name="xxx.weblogic"> <task name="wldeploy"> <message priority="warn">Message which isn't really a warning"</message> </task> </target> </build> </cruisecontrol> In the cruisecontrol XSL template the current selection for the task list is: <xsl:variable name="tasklist" select="/cruisecontrol/build//target/task"/> What I would like is something which selects the tasklist in the same way, but doesn't include any target nodes which have the attribute name="*weblogic" where * is a wildcard. I have tried <xsl:variable name="tasklist" select="/cruisecontrol/build//target[@name!='*weblogic']/task"/> but this doesn't seem to have worked. I'm not an expert with XSLT, and just want to get this fixed so I can carry on the real development of the project. Any help is much appreciated.

• Web UI element to represent two different micro-views of data in the same spot?

  - by Chris McCall

  I've been tasked with laying out a portion of a screen for a customer care (call center) app that serves as sort of a header/summary block at the top of the screen. Here's what it looks like: The important part is in the red box. That little tooltip is the biz's vision for how to represent both the numeric SiteId and the textual Site Name all in the same piece of screen real estate. I asked, and the business thinks the Name is more important than the ID, but lists the Id by default, because the Name can't be truncated in the display, and there's only so much horizontal room to put the data. So they go with the Id, because it's fewer characters, and then they have the user mouse-over the Id to display the name (presumably because the tooltip can be of unlimited width and since it's floating over the rest of the screen, the full name will always be displayed. So, here's my question: Is there some better UI metaphor that I don't know about that could get this job done, while meeting the following constraints?: Does not require the mouse (uses a keyboard shortcut to do the "reveal") Allows the user to copy and paste the name Will not truncate the name Provides for the display of both the ID and name in the same spot Works with IE7

• WPF A good way to make a view/edit control?

  - by Jefim

  Hi, this is just a question to discuss - what is the best way to make a view/edit control in WPF? E.g. we have an entity object Person, that has some props (name, surname, address, phone etc.). One presentation of the control would be a read-only view. And the other would have the edit view for this same person. Example: <UserControl x:Name="MyPersonEditor"> <Grid> <Grid x:Name="ViewGrid" Visibility="Visible"> <TextBlock Text="Name:"/> <TextBlock Text="{Binding Person.Name}"/> <Button Content="Edit" Click="ButtonEditStart_Click"/> </Grid> <Grid x:Name="EditGrid" Visibility="Collapsed"> <TextBlock Text="Name:"/> <TextBox Text="{Binding Person.Name}"/> <Button Content="Save" Click="ButtonEditEnd_Click"/> </Grid> </Grid> </UserControl> I hope that the idea is clear. The two options I see right now two grids with visibility switching and a TabControl without its header panel This is just a discussion question - not much trouble with it, yet I am just wondering if there are any other possibilities and elegant solutions to this.

• form element not showing up after adding in through jquery

  - by ooo

  inside a jquery method (on a click event of a button) i have the following code: $(selector).html("<form action='/Tracker/CopyFood' method='post'><input type='hidden' name='Id' value=" + id + "><input class='very-small-input' type='text' name='Quantity' value='1' /> for <select name='Date'><option value='Today'>Today</option><option value='Yesterday'>Yesterday</option></select><select name='Meal'><option value='Breakfast'>Breakfast</option><option value='Lunch'>Lunch</option><option value='Dinner'>Dinner</option><option value='Evening Snack'>Evening Snack</option></select><input type='button' class='submitCopyFood' value='Add'> or <div style='display:inline' class='CancelCopy'>Cancel</div></form> "); it seems to work on the screen, but the button click "submitCopyFood" wasn't firing. When i click "View Selection Source" in firefox, i see the issue. All i see is this: <input name="Id" value="128" type="hidden"><input class="very-small-input" name="Quantity" value="1" type="text"> for <select name="Date"><option value="Today">Today</option><option value="Yesterday">Yesterday</option></select><select name="Meal"><option value="Breakfast">Breakfast</option><option value="Lunch">Lunch</option><option value="Dinner">Dinner</option><option value="Evening Snack">Evening Snack</option></select><input class="submitCopyFood" value="Add" type="button"> or <div style="display: inline;" class="CancelCopy">Cancel</div> Its like i never added the form anywhere. Is there any reason why i dont see the: <form action='/Tracker/CopyFood' method='post'> or the </form> in the source code inside the selected source. Is there something special that i need to do here?

• When using a repository is it possible for a type to return a Func that the repository uses to test for existing entities?

  - by Scott Rickman

  For example given a Factory with a method public static T Save<T>(T item) where T : Base, new() { /* item.Id == Guid.Empty therefore item is new */ if (item.Id == Guid.Empty && repository.GetAll<T>(t => t.Name == item.Name)) { throw new Exception("Name is not unique"); } } how do I create a property of Base (say MustNotAlreadyExist) so that I can change the method above to public static T Save<T>(T item) where T : Base, new() { /* item.Id == Guid.Empty therefore item is new */ if (item.Id == Guid.Empty && repository.GetAll<T>(t.MustNotAlreadyExist)) { throw new Exception("Name is not unique"); } } public class Base { ... public virtual Expression<Func<T, bool>> MustNotAlreadyExist() { return (b => b.Name == name); /* <- this clearly doesn't work */ } } and then how can I override MustNotAlreadyExist in Account : Base public class Account : Base { ... public override Expression<Func<T, bool>> MustNotAlreadyExist() { return (b => b.Name == name && b.AccountCode == accountCode); /* <- this doesn't work */ } ... }

• (PHP) How do I get XMLReader behave like SimpleXML with Xpath? (Large directory like XML file)

  - by AESM

  So, I've got this huge XML file (10MB and up) that I want to parse and I figured instead of using SimpleXML, I'd better use XMLReader. Since the performance should be way better, right? But since XMLReader doesn't work with XPath... The xml is like this: <root name="bookmarks"> * <dir name="A directory"> <link name="blablabla"> <dir name="Sub directory"> ... </dir> * </dir> * <link name="another link"> </root> With SimpleXML combined with Xpath, I would simple do like: $xml = simplexml_load_file('/xmlFile.xml'); $xml-xpath('/root[@name]/dir[@name="A directory"]/dir[@name="Sub directory"]'); Which is so simple. But how do I do this with just using XMLReader? Ps. I'm converting the resulting node to DOM/SimpleXML to get its inner contents. Like this: $node = $xr-expand(); $dom = new DomDocument(); $n = $dom-importNode($node, true); $dom-appendChild($n); $selectedRoot = simplexml_import_dom($dom); Is this ok? ... Thanks!

• RESTful API: How to model JSON representation?

  - by Jan P.

  I am designing a RESTful API for a booking application. You can request a list of accommodations. And that's where I don't really know how to design the JSON represenation. This is my XML representation: <?xml version="1.0" encoding="utf-8"?> <accommodations> <accommodation> <name>...</name> <category>couch</category> </accommodation> <accommodation> <name>...</name> <category>room</category> </accommodation> <accommodations> My first try to convert this to JSON resulted in this output (1): { "0": { "name": "...", "category": "couch" }, "1": { "name": "...", "category": "room" } } But as I looked how others APIs did it, I found something looking more like this (2): [ { "name": "...", "category": "couch" }, { "name": "...", "category": "room" } ] I know version 1 is an object, and version 2 an array. But which one is better in this case?

• How to take value from radio selection and pass that value into a hidden inputs value attribute?

  - by Matthew

  Hello guys, I need to know if this can be done and if so can someone push me in the right direction. Okay I have a series of radio buttons: <input type="radio" name="level_id" id="radio1" value="XXXX" class="radio1" /> <label for="radio1">choice 1</label> <input type="radio" name="level_id" id="radio2" value="XXXX" class="radio2" /> <label for="radio2">choice 2</label> <input type="radio" name="level_id" id="radio3" value="XXXX" class="radio3" /> <label for="radio3">choice 3</label> <label for="radio4">second choice1</label> <input type="radio" name="level_id" id="radio4" value="1" class="radio4" /> <label for="radio5">second choice2</label> <input type="radio" name="level_id" id="radio5" value="2" class="radio5" /> <label for="radio6">second choice3</label> <input type="radio" name="level_id" id="radio6" value="3" class="radio6" /> Now what I am looking to do is if someone selects CHOICE 1 and then selects SECOND CHOICE1 I would like to pass the value of SECOND CHOICE1 into the value of a hidden input. <input type="hidden" name="sub_source" id="sub_source" value="" /> So that when the form is ready to submit the value that gets passed would be: <input type="hidden" name="sub_source" id="sub_source" value="1" />

• Unable to set password in IIS 8 for Domain User as ApplicationPool Identity

  - by Niels R.

  I'm trying to set a Domain User account as ApplicationPool Identity in IIS 8 (Windows 2012). When trying this using the IIS Management Console I always get an error: Value does not fall within the expected range. When trying to set the identity using appcmd.exe it fails on both the command setting the username and password or the command only setting the password. Setting the username is no problem. Trying to set both the username and password [FAIL]: >appcmd set config /section:applicationPools /[name='AppPoolName'].processModel.identityType:SpecificUser /[name='AppPoolName'].processModel.userName:DOMAIN\Username /[name='AppPoolName'].processModel.password:P4ssW0rd Applied configuration changes to section "system.applicationHost/applicationPools" for "MACHINE/WEBROOT/APPHOST" at configuration commit path "MACHINE/WEBROOT/APPHOST" ERROR ( hresult:80070057, message:Failed to commit configuration changes.
