• Java Swing - Problem in JSpinner

  - by Yatendra Goel

  I am developing a Java Desktop Application and designing the GUI with the help of Netbeans Swing GUI builder. I want to use a JSpinner in my app. I have dragged and dropped it to a JPanel. Now, I want to set its two properties: First, It should display numbers in the range of 1 to 50. Neither less than 1 nor greater than 50. How can I set that range? Second, when I try to get the value of it by spinner.getValue() it returns an Object. As my spinner's data type is Integer, would it be better to downcast the Object into Integer or Is there any other way to get that numeric value?

• Spring 3.0 MVC mvc:view-controller tag

  - by gouki

  Here's a snippet of my mvc-config.xml <bean class="org.springframework.web.servlet.view.InternalResourceViewResolver"> <property name="prefix" value="/WEB-INF/views/"/> <property name="suffix" value=".jsp"/> </bean> <mvc:view-controller path="/index" view-name="welcome"/> <mvc:view-controller path="/static/login" view-name="/static/login"/> <mvc:view-controller path="/login" view-name="/static/login"/> I have the welcome.jsp on /WEB-INF/view/ directory and login.jsp on /WEB-INF/view/static/. This work for '/index' and '/login' paths. But I'm getting 404 response for '/static/login' when invoked from the browser. I'm expecting that '/static/login/' and '/login' should behave the same. What could be wrong here? Would appreciate any help. Thanks!

• New replicaset resident memory is larger than the existing sets

  - by eded

  From the mongodb tutorial of how to resync a set, I wipe all the files in /data/db and restart the mongod process to resync the data. Everything looks ok, I get the same number of documents as the existing two sets(primary and one secondary). However, when I check the memory on MMS. it shows me my new resynced set/mongod process has a different memory status value than the other two. For existing twos using db.serverStatus.mem shows like the following: "mem" : { "bits" : 64, "resident" : 239, "virtual" : 66348, "supported" : true, "mapped" : 32865, "mappedWithJournal" : 65730 } however, the new resynced set shows like: "mem" : { "bits" : 64, "resident" : 1239, "virtual" : 52447, "supported" : true, "mapped" : 25700, "mappedWithJournal" : 51400 } the resynced resident memory is 6-10 times more than the existing ones. I wouder if it is normal because all data comes in suddenly during the resyncing?? and even virtual and mapped value are different too. Can anyone explain?? thanks

• jQuery way to handle select lists, radio buttons and checkboxes

  - by Álvaro G. Vicario

  When I handle HTML form elements with jQuery, I always end up with an ugly mix of jQuery syntax and plain JavaScript like, e.g.: function doStuff($combo){ if( $combo.get(0).options[$combo.get(0).selectedIndex].value=="" ){ var txt = ""; }else{ var txt = $combo.get(0).options[$combo.get(0).selectedIndex].text; } var $description = $combo.closest("div.item").find("input[name$=\[description\]]"); $description.val(txt); } Are there standard jQuery methods to handle typical operations on elements like <select>, <input type="radio"> and <input type="checkbox">? With typical, I mean stuff like reading the value of the selected radio button in a group or replacing elements in a selection list. I haven't found them in the documentation but I admit that method overloading can make doc browser kind of tricky.

• Why can I create a table with PRIMARY KEY on a nullable column?

  - by AlexKuznetsov

  The following code creates a table without raising any errors: CREATE TABLE test( ID INTEGER NULL, CONSTRAINT PK_test PRIMARY KEY(ID) ) Note that I cannot insert a NULL, as expected: INSERT INTO test VALUES(1),(NULL) ERROR: null value in column "id" violates not-null constraint DETAIL: Failing row contains (null). ********** Error ********** ERROR: null value in column "id" violates not-null constraint SQL state: 23502 Detail: Failing row contains (null). Why can I create a table with a self-contradictory definition? ID column is explicitly declared as NULLable, and it is implicitly not nullable, as a part of the PRIMARY KEY. Does it make sense? Edit: would it not be better if this self-contradictory CREATE TABLE just failed right there?

• empty() returning TRUE on object's non-empty property

  - by Michal M

  I've got a very weird and unexpected problem. empty() is returning TRUE on a non-empty property for a reason unknown to me. class MyObject { private $_property; public function __construct($property) { $this->_property = $property; } public function __get($name) { $priv_name = "_{$name}"; if (isset($this->$priv_name)) { return $this->$priv_name; } else { return NULL; } } } $obj = new MyObject('string value'); echo $obj->property; // Output 'string value' echo empty($obj->property); // Output 1 (means, that property is empty) Would this mean, that the __get() magic function is not called when using empty()? btw. I'm running PHP version 5.0.4

• Changing all CSS styles with a property via Jquery

  - by Joe

  On a page I include some css eg: <style type='test/css'> .myBox{ color:#000000; border:#FFFFFF; padding:4px; } .myBox2{ color:#000000; border:#FFFFFF; padding:4px; } </style> I want to then change the "color" property set within both myBox and myBox2 in jquery, without knowing the actual name (myBox, myBox2) of the css style. In otherwords, I want to update ALL css styles on the page where color = certain value, and then also update border where = certain value. An example (not valid code) might be: $("all css [color:#000000]").html("#FF0000"); How could this be possible using jquery?

  - by Homam

  Hi, I have an HtmlInputText in an EditItemTemplate in a DataGrid, This control is bound with a value from the SqlDataSource I want to set in this control two values the JOB_CODE_ID and the JOB_CODE instead of just JOB_CODE. I used to use Tag in the WinForms to set values such this, but in I don't know similar way in ASP.Net. In my situation I can't use a hidden control to save the JOB_CODE_ID there, Is there any way to set two values in a HtmlInputText control ? The code: <input type="text" ID="JOB_CODETextBox" runat="server" value='<%# Bind("JOB_CODE") %>' /> Thanks in advance.

• Use a ContextLoaderListener in accordance with DispatchServlet

  - by Phuong Nguyen de ManCity fan

  I want to use both ContextLoaderListener (so that I can pass Spring Beans to my servlet) as well as DispatchServlet (Spring MVC). However, currently I have to pass init param to these both class initializer: <param-name>contextConfigLocation</param-name> <param-value> /WEB-INF/spring/app-config.xml </param-value> So, I use the same xml for these both classes. Wonder if it would lead to my beans being initialized twice? If yes, how would I do to avoid that?

Is is possible to achieve using javascript/jquery? I could have many such self closing tag pairs s1 and s2 with a unique value for "ind" for the pair indicating that the text within them needs to be highlighted.

• Property Scope (Iphone)

  - by Hank

  Hello All. I am having trouble accessing a declared property and I think I am missing something fundamental about the nature of properties and perhaps view controllers. Here's what I'm doing so far: declaring a property "myPhone" in a root view controller called RootViewController. grabbing a phone number from a modally presented people picker setting "myPhone" to the value from the people picker (from within shouldContinueAfterSelectingPerson of ABPeoplePickerNavigationController) trying to access "myPhone" from another modally presented view controller "myPhone" continues to NSLog to null despite trying every permutation of self.myPhone, super, RootViewController, etc. to try and access the value I set. What am I missing?

• MSBuild conditionals depending on task parameters

  - by jalf

  In MSBuild it's straightforward to define, say, a PropertyGroup which depends on the value of a property Foo: <PropertyGroup Conditional="'$(Foo)'=='Bar'" /> Is it also possible for the conditional to depend on a task parameter? For example, I'd like to use the value of the Link task's SubSystemparameter roughly like this: <PropertyGroup Conditional="'$(Link/SubSystem)'=='Console'" /> but don't know if it is possible, and if it is, what the correct syntax is. I'm pretty new to MSBuild though, so it's perfectly possible that I've missed something.

• Update Statement Updates 0 Rows via the C# Winform Application?

  - by peace

  First of all, please help me out! I can not take this anymore. I could not find where the error is located. Here is my problem: I'm trying to update a row via c# winform application. The update query generated from the application is formatted correctly. I tested it in the sql server environment, it worked well. When i run it from the application i get 0 rows updated. Here is the snippet that generates the update statement using reflection - don't try to figure it out. Carry on reading after the code portion: public void Update(int cusID) { SqlCommand objSqlCommand = new SqlCommand(); Customer cust = new Customer(); string SQL = null; try { if ((cusID != 0)) { foreach (PropertyInfo PropertyItem in this.GetType().GetProperties()) { if (!(PropertyItem.Name.ToString() == cust.PKName)) { if (PropertyItem.Name.ToString() != "TableName") { if (SQL == null) { SQL = PropertyItem.Name.ToString() + " = @" + PropertyItem.Name.ToString(); } else { SQL = SQL + ", " + PropertyItem.Name.ToString() + " = @" + PropertyItem.Name.ToString(); } } else { break; } } } objSqlCommand.CommandText = "UPDATE " + this.TableName + " SET " + SQL + " WHERE " + cust.PKName + " = @cusID AND PhoneNumber = " + "'" + "@phNum" + "'"; foreach (PropertyInfo PropertyItem in this.GetType().GetProperties()) { if (!(PropertyItem.Name.ToString() == cust.PKName)) { if (PropertyItem.Name.ToString() != "TableName") { objSqlCommand.Parameters.AddWithValue("@" + PropertyItem.Name.ToString(), PropertyItem.GetValue(this, null)); } else { break; } } } objSqlCommand.Parameters.AddWithValue("@cusID", cusID); objSqlCommand.Parameters.AddWithValue("@phNum", this.PhoneNumber); DAL.ExecuteSQL(objSqlCommand); } else { //AppEventLog.AddWarning("Primary Key is not provided for Update.") } } catch (Exception ex) { //AppEventLog.AddError(ex.Message.ToString) } } This part below: objSqlCommand.CommandText = "UPDATE " + this.TableName + " SET " + SQL + " WHERE " + cust.PKName + " = @cusID AND PhoneNumber = " + "'" + "@phNum" + "'"; generates dml: UPDATE CustomerPhone SET PhoneTypeID = @PhoneTypeID, PhoneNumber = @PhoneNumber WHERE CustomerID = @cusID AND PhoneNumber = '@phNum' @PhoneTypeID and @PhoneNumber are gotten from two properties. We assigned the value to these properties in the presentation layer from the user input text box. The portion below where fetches the values: objSqlCommand.Parameters.AddWithValue("@" + PropertyItem.Name.ToString(), PropertyItem.GetValue(this, null)); The code below fills the values of WHERE: objSqlCommand.Parameters.AddWithValue("@cusID", cusID); objSqlCommand.Parameters.AddWithValue("@phNum", this.PhoneNumber); The final code should look as: UPDATE CustomerPhone SET PhoneTypeID = 7, PhoneNumber = 999444 WHERE CustomerID = 500 AND PhoneNumber = '911'; Phone type id is 7 - user value that is taken from text box Phone number is 999444 - user value that is taken from text box The above final update statement works on the sql environment, but when running via the application, the execute non query runs ok and gets 0 rows updated! I wonder why?

• When can argv[0] have null ?

  - by andrew-dufresne

  What I have understand about passing arguments to main() from command line is that argc has a minimum value of 1 and argv[0] will always have the program name with its path in it. If arguments are provided at the command line, then argc will have a value greater than one and argv1 to argv[argc-1] will have those arguments. Now a paragraph at this link says that argv[0] will be a string containing the program's name or a null string if that is not available. Now, how and when can argv[0] have null string? I mean program name with its path will always be available so when can it be null? Writer says that "if that is not available" but when and how it is possible that program name will not be available? Thanks for your time and support. Regards
