• After rich:extendedDataTable sortby, other actions are not getting executed

  - by kksachin

  I have several tabs and one of the tabs uses rich:extendedDataTable. If sortBy is clicked in the page where table is used and if I navigate to another page, it looks for the bean of the old page and throws an error saying that sortyBy of the column is undefined. E.g. If I use sortBy on userId in tab1 (where the column must have sortBy="#{data.userId}") and then I click on tab2, it looks for the data.userId and throws an error. I am using Richfaces version 3.2.2SR1. Can anyone help me on this? Here is the complete trace: javax.el.PropertyNotFoundException: /amendapplication/historyDetails.xhtml @33,174 sortBy="#{data.statusChangeTime}": Property 'statusChangeTime' not found on type uk.gov.wales.rpd.domain.applicationmanagement.ApplicationAttributeEntity com.sun.facelets.el.TagValueExpression.getValue(TagValueExpression.java:73) org.richfaces.model.impl.expressive.ValueBindingExpression.evaluate(ValueBindingExpression.java:59) org.richfaces.model.impl.expressive.ObjectWrapperFactory.wrapObject(ObjectWrapperFactory.java:189) org.richfaces.model.ModifiableModel$RowKeyWrapperFactory.wrapObject(ModifiableModel.java:57) org.richfaces.model.impl.expressive.ObjectWrapperFactory$2.convert(ObjectWrapperFactory.java:177) org.richfaces.model.impl.expressive.ObjectWrapperFactory.convertList(ObjectWrapperFactory.java:138) org.richfaces.model.impl.expressive.ObjectWrapperFactory.wrapList(ObjectWrapperFactory.java:175) org.richfaces.model.ModifiableModel.sort(ModifiableModel.java:235) org.richfaces.model.ModifiableModel.modify(ModifiableModel.java:206) org.richfaces.component.UIExtendedDataTable.createDataModel(UIExtendedDataTable.java:310) org.ajax4jsf.component.UIDataAdaptor.getExtendedDataModel(UIDataAdaptor.java:621) org.ajax4jsf.component.UIDataAdaptor.setRowKey(UIDataAdaptor.java:339) org.ajax4jsf.component.UIDataAdaptor.iterate(UIDataAdaptor.java:1034) org.ajax4jsf.component.UIDataAdaptor.processDecodes(UIDataAdaptor.java:1158) org.ajax4jsf.component.UIDataAdaptor.processDecodes(UIDataAdaptor.java:1168) javax.faces.component.UIForm.processDecodes(UIForm.java:209) org.ajax4jsf.component.AjaxViewRoot$1.invokeContextCallback(AjaxViewRoot.java:392) org.ajax4jsf.component.AjaxViewRoot.processPhase(AjaxViewRoot.java:238) org.ajax4jsf.component.AjaxViewRoot.processDecodes(AjaxViewRoot.java:409) com.sun.faces.lifecycle.ApplyRequestValuesPhase.execute(ApplyRequestValuesPhase.java:78) com.sun.faces.lifecycle.Phase.doPhase(Phase.java:100) com.sun.faces.lifecycle.LifecycleImpl.execute(LifecycleImpl.java:118) javax.faces.webapp.FacesServlet.service(FacesServlet.java:265) org.apache.myfaces.webapp.filter.ExtensionsFilter.doFilter(ExtensionsFilter.java:341) org.ajax4jsf.webapp.BaseXMLFilter.doXmlFilter(BaseXMLFilter.java:177) org.ajax4jsf.webapp.BaseFilter.handleRequest(BaseFilter.java:267) org.ajax4jsf.webapp.BaseFilter.processUploadsAndHandleRequest(BaseFilter.java:380) org.ajax4jsf.webapp.BaseFilter.doFilter(BaseFilter.java:507) org.jboss.web.tomcat.filters.ReplyHeaderFilter.doFilter(ReplyHeaderFilter.java:96)

• Should I release NSString before assigning a new value to it?

  - by Elliot Chen

  Hi, Please give me some suggestions about how to change a NSString variable. At my class, I set a member var: NSString *m_movieName; ... @property(nonatomic, retain) NSString *m_movieName; At viewDidLoad method, I assign a default name to this var: -(void)viewDidLoad{ NSString *s1 = [[NSString alloc] initWithFormat:@"Forrest Gump"]; self.m_movieName = s1; ... [s1 release]; [super viewDidLoad] } At some function, I want to give a new name to this var, so I did like: -(void)SomeFunc{ NSString *s2 = [[NSString alloc] initWithFormat:@"Brave Heart"]; //[self.movieName release]; // ??????? Should perform here? self.m_moiveName = s2; [s2 release]; } I know, NSString* var is just a pointer to an allocated memory block, and 'assign' operation will increment this memory block's using count. For my situation, should I release m_movieName before assigning a value to it? If I do not release it (via [self.movieName release]), when and where will the previous block be released? Thanks for your help very much!

• Javascript permission denied - different port

  - by Grnbeagle

  Hi, I have a rails app running on port 3000. The page in question has an iframe and I need to resize it depending on the height of the content loaded in the iframe. <iframe id="ifrm_col3" name="ifrm_col3" frameborder="0" src="<%=invite_path(@invite.alias)%>" onload="util.resize_iframe('ifrm_col3');"></iframe> The resize function is here: util.resize_iframe = function(frame_id) { var h = document.getElementById(frame_id).contentWindow.document.body.scrollHeight; document.getElementById(frame_id).height = h; } After the iframe loads, I see this error in FireBug: Error: Permission denied for <http://192.168.0.157> to get property Window.document from <http://192.168.0.157:3000>. Source File: http://192.168.0.157:3000/javascripts/application.js?1268327481 Line: 84 The src of iframe is a relative path, but I'm not sure why the port info from the parent page is not retained. Is there any workaround to this problem? I tried creating a function in the parent page and calling it from the iframe, but ran into the same issue. Due to extra features in the site, I need to stick to port 3000 for the rails app. Any suggestion is appreciated.

• cookie name is truncated in Servlet 3.0 HttpServletRequest (Glassfish V3)

  - by idplmal

  I'm porting our Web authentication/authorization middleware for use in containers implementing the new servlet 3.0 API (Glassfish V3 in this case). The middleware pulls cookies from the HttpServletRequest filtering on cookies with names of the form "DACS:FEDERATION::JURISDICTION:username". This works fine in the version 2.5 servlet API but is broken in 3.0. The cookie names in 3.0 are being truncated at the first ":" in the name. I understand that the servlet 3.0 implementation defaults to RFC 2109 cookies which are more restrictive about cookie names than the old Netscape spec (":" is among the characters not allowed in RFC 2109 cookie names). Digging into the servlet 3.0 source code, it appears that the use of RFC2109 names can be disabled by setting a System property "org.glassfish.web.rfc2109.cookie_names_enforced" to false. I've tried this to no avail. But besides that, the code that uses checks cookie names is in the constructor for Cookie, and it would appear that the truncation is occurring elsewhere. So - finally - the question. Have others bumped into such issues in the servlet 3.0 API and have you found a work around?

• EF Forced Concurrency Checks

  - by Imran

  Hi, I have an issue with EF 4.0 that I hope someone can help with. I currently have an entity that I want to update in a last in wins fashion (i.e. ignore concurrency checks and just overwrite whats in the db with what is submitted). It seems Entity Framework not only includes the primary key of the entity in the where clause of the generated sql, but also any foreign key fields. This is annoying as it means that I don't get true last in wins semantics and need to know what value the fk field had before the update or I get a concurrency exception. I am aware that this can be short circuited by including a foreign key field as well as the navigation property on the entity. I would like to avoid this if possible as it's not a very clean solution. I was just wondering if there was any other way to override this behaviour? It seems like more of a bug than a feature. I have no problem with ef doing concurrency checks if I instruct it to do so but not being able to bypass concurrency completely is a bit of a hindrance as there are many valid scenarios where this is not needed

• How to tell if you touched a CCLabel? (Cocos2d Question)

  - by RexOnRoids

  How to tell if you touched a CCLabel? The following code obviously does not work well enough because it only tests for point equality. Naturally touch point will not necessarily be equal to the position property of the CCLabel (CCNode). How to I tell if a Touch point has fallen within the "rectangle?" of the CCLabel? - (void)ccTouchesEnded:(NSSet *)touches withEvent:(UIEvent *)event { for( UITouch *touch in touches ) { CGPoint location = [touch locationInView: [touch view]]; location = [[CCDirector sharedDirector] convertToGL:location]; self.myGraphManager.isSliding = NO; if(CGPointEqualToPoint(location, label1.position)){ NSLog(@"Label 1 Touched"); }else if(CGPointEqualToPoint(location, label2.position)){ NSLog(@"Label 2 Touched"); }else if(CGPointEqualToPoint(location, label3.position)){ NSLog(@"Label 3 Touched"); }else if(CGPointEqualToPoint(location, label4.position)){ NSLog(@"Label 4 Touched"); }else if(CGPointEqualToPoint(location, label5.position)){ NSLog(@"Label 5 Touched"); }else if(CGPointEqualToPoint(location, label6.position)){ NSLog(@"Label 6 Touched"); } NSLog(@"Touch Made!"); } }

• backbone.js Model.get() returns undefined, scope using coffeescript + coffee toaster?

  - by benipsen

  I'm writing an app using coffeescript with coffee toaster (an awesome NPM module for stitching) that builds my app.js file. Lots of my application classes and templates require info about the current user so I have an instance of class User (extends Backbone.Model) stored as a property of my main Application class (extends Backbone.Router). As part of the initialization routine I grab the user from the server (which takes care of authentication, roles, account switching etc.). Here's that coffeescript: @user = new models.User @user.fetch() console.log(@user) console.log(@user.get('email')) The first logging statement outputs the correct Backbone.Model attributes object in the console just as it should: User _changing: false _escapedAttributes: Object _pending: Object _previousAttributes: Object _silent: Object attributes: Object account: Object created_on: "1983-12-13 00:00:00" email: "[email protected]" icon: "0" id: "1" last_login: "2012-06-07 02:31:38" name: "Ben Ipsen" roles: Object __proto__: Object changed: Object cid: "c0" id: "1" __proto__: ctor app.js:228 However, the second returns undefined despite the model attributes clearly being there in the console when logged. And just to make things even more interesting, typing "window.app.user.get('email')" into the console manually returns the expected value of "[email protected]"... ? Just for reference, here's how the initialize method compiles into my app.js file: Application.prototype.initialize = function() { var isMobile; isMobile = navigator.userAgent.match(/(iPhone|iPod|iPad|Android|BlackBerry)/); this.helpers = new views.DOMHelpers().initialize().setup_viewport(isMobile); this.user = new models.User(); this.user.fetch(); console.log(this.user); console.log(this.user.get('email')); return this; }; I initialize the Application controller in my static HTML like so: jQuery(document).ready(function(){ window.app = new controllers.Application(); }); Suggestions please and thank you!

• How to get a handle to all JCheckBox objects in order to loop?

  - by EmmyS

  I'm very new to Java and am having some issues looping through JCheckBoxes on a UI. The idea is that I have a bunch of checkboxes (not in a group because more than one can be selected.) When I click a JButton, I want to build a string containing the text from each selected checkbox. The issue I'm having is that our instructor told us that the checkboxes need to be created via a method, which means (see code below) that there isn't a discrete instance name for each checkbox. If there were, I could say something like if(checkBox1.isSelected()) { myString.append(checkBox.getText()); } That would repeat for checkBox2, checkBox3, and so on. But the method provided to us for adding checkboxes to a panel looks like this: public class CheckBoxPanel extends JPanel { private static final long serialVersionUID = 1L; public CheckBoxPanel(String title, String... options) { setBorder(BorderFactory.createTitledBorder(BorderFactory .createEtchedBorder(), title)); setLayout(new BoxLayout(this, BoxLayout.Y_AXIS)); // make one checkbox for each option for (String option : options) { JCheckBox b = new JCheckBox(option); b.setActionCommand(option); add(b); } } } This is called like this: toppingPanel = new CheckBoxPanel("Each Topping $1.50", "Tomato", "Green Pepper", "Black Olives", "Mushrooms", "Extra Cheese", "Pepperoni", "Sausage"); So I now have a panel that contains a border with the title "Each Topping $1.50", and 7 visible checkboxes. What I need to do is get a list of all the selected toppings. We are not supposed to use an ActionListener for each checkbox, but rather get the list when a button is clicked. I'm feeling really clueless here, but I just can't figure out how to get the isSelected property of the checkboxes when the individual checkboxes don't have instance names. Ideally I'd like to somehow add all the checkboxes to an array and loop through the array in the button's action listener to determine which ones are checked, but if I have to check each one individually I will. I just can't figure out how to refer to an individual checkbox when they've been created dynamically.

• Adding a Taxonomy Filter to a Custom Post Type

  - by ken

  There is an amazing conversation from about two years ago on the Wordpress Answer site where a number of people came up with good solutions for adding a taxonomy filter to the admin screen for your custom post types (see URL for screen I'm referring to): http://[yoursite.com]/wp-admin/edit.php?s&post_status=all&post_type=[post-type] Anyway, I loved Michael's awesome contribution but in the end used Somatic's implementation with the hierarchy option from Manny. I wrapped it in a class - cuz that's how I like to do things -- and it ALMOST works. The dropdown appears but the values in the dropdown are all looking in the $_GET property for the taxonomies slug-name that you are filtering by. For some reason I don't get anything. I looked at the HTML of the dropdown and it appears ok to me. Here's a quick screen shot for some context: You can tell from this that my post-type is called "exercise" and that the Taxonomy I'm trying to use as a filter is "actions". Here then is the HTML surrounding the dropdown list: <select name="actions" id="actions" class="postform"> <option value="">Show all Actions</option> <option value="ate-dinner">Ate dinner(1)</option> <option value="went-running">Went running(1)</option> </select> I have also confirmed that all of the form elements are within the part of the DOM. And yet if I choose "Went running" and click on the filter button the URL query string comes back without ANY reference to what i've picked. More explicitly, the page first loads with the following URL: /wp-admin/edit.php?post_type=exercise and after pressing the filter button while having picked "Went Running" as an option from the actions filter: /wp-admin/edit.php?s&post_status=all&post_type=exercise&action=-1&m=0&actions&paged=1&mode=list&action2=-1 actually you can see a reference to an "actions" variable but it's set to nothing and as I now look in detail it appears that the moment I hit "filter" on the page it resets the filter dropdown to the default "Show All Actions". Can anyone help me with this?

• Trouble with object injection in Spring.Net

  - by Abdel Olakara

  Hi all, I have a issue with my Spring.Net configuration where its not injecting an object. I have a CommService to which an object named GeneralEmail is injected to. Here is the configuration: <!-- GeneralMail Object --> <object id="GeneralMailObject" type="CommUtil.Email.GeneralEmail, CommUtil"> <constructor-arg name="host" value="xxxxx.com"/> <constructor-arg name="port" value="25"/> <constructor-arg name="user" value="[email protected]"/> <constructor-arg name="password" value="xxxxx"/> <constructor-arg name="template" value="xxxxx"/> </object> <!-- Communication Service --> <object id="CommServiceObject" type="TApp.Code.Services.CommService, TApp"> <property name="emailService" ref="GeneralMailObject" /> </object> The communication service object is again injected to many other aspx pages & service. In one scenario, I need to call the commnucation service from an static WebMethod. I try doing: CommService cso = new CommService(); But when i try to get the emailService object, its null! why didn't the spring inject the GeneralMail object into my cso object? What am I doing wrong and how do I access the object from spring container. Thanks in advance for the suggestions and solutions. Reagrds, Abdel Olakara

• Intellisense for custom config section problem with namespaces

  - by Quick Joe Smith

  I have just rolled a custom configuration section, created an accompanying schema document for Intellisense and added it to the Web.config's Schemas property as per Michael Stum's answer to another similar question. Unfortunately, and possibly due to me creating the XSD by hand with limited knowledge, the Intellisense relies on an xmlns attribute pointing to my XSD file's namespace being present in the custom config element. However, when running the project I get an Unrecognized attribute 'xmlns'. Note that attribute names are case-sensitive error. I could probably just modify my XSD file to define the xmlns attribute for that element, however I am wondering if this is just a bandaid fix to a larger problem. I must confess I don't have a very good understanding of XML namespaces so this might be an oppportunity to set me straight on a few things. Here is the attributes for my XSD file's root xs:schema element: <xs:schema id="awesomeConfig" targetNamespace="http://awesome.com/schemas" xmlns="http://awesome.com/schemas" elementFormDefault="qualified" xmlns:xs="http://www.w3.org/2001/XMLSchema"> ... </xs:schema> And on creating the element in the Web.config file, Visual Studio 2008 automatically appends: <awesomeConfig xmlns="http://awesome.com/schemas"></awesomeConfig> So have I misunderstood the meaning of the xs:schema attributes at all, or is the proper solution as simple as it seems?

• MVC 2 - Name Attributes on HTML Input Field when using Parent/Child Entities

  - by Click Ahead

  Hi All, I'm pretty new to MVC 2 using the Entity Framework. I have two tables Company {ID int identity PK,Name nvarchar} and User {ID int identity PK,UserName nvarchar,CompanyID int FK}. A Foreign Key exists between User and Company. I generated my ADO.NET Entity Data Model, a Controller and a view to insert a record. My HTML form has the fields Company and UserName and the idea is when I click save a Company and User is inserted into the database. Sounds straight forward right! My question is as follows: I created a strongly-typed view derived from my 'User' entity. I'm using the the html helper Html.TextBoxFor(model = model.Organisation.Name) but the html name attribute for this input field is 'Organisation.Name'. My problem with this is that the dot throws up all sorts of issues in JQuery, which sees this as a property. If I want to change the name I read that I can use DataAnnotations but because I used the Entity Designer this involves using Buddy Classes. Seems like a bit of overkill just to change the html name attribute on this input field. Am I approaching this the right way or am I missing something here? Thanks for the help !

• DataGridView: how to make scrollbar in sync with current cell selection?

  - by David.Chu.ca

  I have a windows application with DataGridView as data presentation. Every 2 minutes, the grid will be refreshed with new data. In order to keep the scroll bar in sync with the new data added, I have to reset its ScrollBars: dbv.Rows.Clear(); // clear rows SCrollBars sc = dbv.ScrollBars; dbv.ScrollBars = ScrollBars.None; // continue to populate rows such as dbv.Rows.Add(obj); dbv.ScrollBars = sc; // restore the scroll bar setting back With above codes, the scroll bar reappears fine after data refresh. The problem is that the application requires to set certain cell as selected after the refresh: dbv.CurrentCell = dbv[0, selectedRowIndex]; With above code, the cell is selected; however, the scroll bar's position does not reflect the position of the selected cell's row position. When I try to move the scroll bar after the refresh, the grid will jump to the first row. It seems that the scroll bar position is set back to 0 after the reset. The code to set grid's CurrentCell does not cause the scroll bar to reposition to the correct place. There is no property or method to get or set scroll bar's value in DataGriadView, as far as I know. I also tried to set the selected row to the top: dbv.CurrentCell = dbv[0, selectedRowIndex]; dbv.FirstDisplayedScrollingRowIndex = selectedRowIndex; The row will be set to the top, but the scroll bar's position is still out of sync. Not sure if there is any way to make scroll bar's position in sync with the selected row which is set in code?

• How to use a Base ViewModel in Asp.net MVC 2

  - by Picflight

  As I familiarize myself with Asp.Net MVC, I am using MVC 2, I have noticed the use of a BaseViewData class in the Kigg project which I am unsure how to implement. I want each of my ViewModels to have certain values available. Using an iterface comes to mind but I am wondering what the best practice is and how does Kigg do it? Kigg public abstract class BaseViewData { public string SiteTitle { get; set; } // ...other properties } public class UserListViewData : BaseViewData { public string Title { get; set; } // .. other stuff } In my WebForms application I use a BasePage that inherits from System.Web.UI.Page. So, in my MVC project, I have this: public abstract class BaseViewModel { public int SiteId { get; set; } } public class UserViewModel : BaseViewModel { // Some arbitrary ViewModel } Referencing the Kigg methodology, how do I make sure that each of my ViewModel that inherits from the BaseViewModel have the SiteId property? What is the best practice, samples or patterns I should be using?

• How to make a WPF ComboBox editable with custom values

  - by Liam

  I would like to have a combobox that allows selection from a list of values and also allow a custom value from the typed in text. For display reasons the items are a complex type (lets say the combobox item template displays a patch of color and a flag indicating if it is a custom color). public class ColorLevel { public decimal Intensity { get; set; } public bool IsCustom { get; set; } public Color BaseColor { get; set; } public override ToString() { return string.Format("{0}", Intensity*100); } } Example items var items = new [] { new ColorLevel { Intensity = 0.9m, IsCustom = false, BaseColor = Color.Red }, new ColorLevel { Intensity = 0.7m, IsCustom = false, BaseColor = Color.Red } } XAML <ComboBox SelectedItem="{Binding Path=SelectedColorLevel}" IsEditable="true" IsTextSearchEnabled="true"> </ComboBox> So the above markup works when an item is selected from the item list. And as you type with the text search the matching items are selected. If the typed text doesn't match an item then the SelectedColorLevel is set to null. The question is at what point (and how) is it best to create a new custom item that can be set to the SelectedColorLevel when the typed text doesn't match an item. For example I would want to assign a new item to the selected value such as new ColorLevel { Intensity = decimal.Parse(textvalue), IsCustom = true } or using an appropriate converter and databinding to the Text property.

• Where to Store ID Field In Silverlight

  - by Blake Blackwell

  I am trying to use the MVVM pattern, and I am wondering where I place an ID value. Do I create a TextBlock that has its visibility property set to collapsed? Or is there a better place to store this kind of data? Currently the command parameter is set to: CommandParameter="{Binding ElementName=Name,Path=Text}" But I'd rather it be something like: CommandParameter="{Binding ElementName=Id,Path=Text}" I'm totally up for suggestions on what the best way there is to do this, since I'm new to this pattern and presentation language. <ListBox x:Name="MyListBox" ItemsSource="{Binding MyData, Mode=TwoWay}" BorderThickness="0"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <CheckBox x:Name="Visible" IsChecked="{Binding Visible, Mode=TwoWay}" Command="{Binding ElementName=MyListBox, Path=DataContext.MyCommand}" CommandParameter="{Binding ElementName=Name,Path=Text}" /> <TextBlock Text="{Binding Name}" /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> EDIT: Option 1 <CheckBox x:Name="Visible" IsChecked="{Binding Visible, Mode=TwoWay}" Command="{Binding ElementName=MyListBox, Path=DataContext.MyCommand}" CommandParameter="{Binding Id}" /> This option gives me just the Id, which is useful in many situations. EDIT: Option 2 <CheckBox x:Name="Visible" IsChecked="{Binding Visible, Mode=TwoWay}" Command="{Binding ElementName=MyListBox, Path=DataContext.MyCommand}" CommandParameter="{Binding}" /> This option gives me the full model, which is even useful for my particular situation.

• JSF 2 f:ajax lifecycle problem

  - by gerry

  The problem is, that if a property is changed during an f:ajax request and a binded panelGroup should be newly created depending on that changed value, the old value is used. This code will explain the problem. Here is the backingbean TestBean: public String getFirst() { return first; } public void setFirst(String first) { this.first = first; } public String getLast() { return last; } public void setLast(String last) { this.last = last; } public String getName(){ return first+" "+last; } public void setDynamicPanel(HtmlPanelGroup panel){ } public HtmlPanelGroup getDynamicPanel(){ Application app = FacesContext.getCurrentInstance().getApplication(); HtmlPanelGroup component = (HtmlPanelGroup)app.createComponent(HtmlPanelGroup.COMPONENT_TYPE); HtmlOutputLabel label1 = (HtmlOutputLabel)app.createComponent(HtmlOutputLabel.COMPONENT_TYPE); label1.setValue(" --> "+getFirst()+" "+getLast()); component.getChildren().add(label1); return component; } and now the jsf/facelet code: <h:form id="form"> <h:panelGrid columns="1"> <h:inputText id="first" value="#{testBean.first}" /> <h:inputText id="last" value="#{testBean.last}" /> <h:commandButton value="Show"> <f:ajax execute="first last" render="name dyn" /> </h:commandButton> </h:panelGrid> <h:outputText id="name" value="#{testBean.name}" /> <h:panelGroup id="dyn" binding="#{testBean.dynamicPanel}" /> </h:form> After the page was initially loaded the outputText and panelGroup shows both "null" as first and last. But after the button is pressed, the outputText is updated well, but the the panelgroup shows again only "null". This is due to the problem, that the "binded method" dynamicPanel is executed before the update of the first and last properties. how can workaround this behaviour or what is wrong with my code?

• ASP.NET DropDownList posting ""

  - by Daniel

  I am using ASP.NET forms version 3.5 in VB I have a dropdownlist that is filled with data from a DB with a list of countries The code for the dropdown list is <label class="ob_label"> <asp:DropDownList ID="lstCountry" runat="server" CssClass="ob_forminput"> </asp:DropDownList> Country*</label> And the code that the list is Dim selectSQL As String = "exec dbo.*******************" ' Define the ADO.NET objects. Dim con As New SqlConnection(connectionString) Dim cmd As New SqlCommand(selectSQL, con) Dim reader As SqlDataReader ' Try to open database and read information. Try con.Open() reader = cmd.ExecuteReader() ' For each item, add the author name to the displayed ' list box text, and store the unique ID in the Value property. Do While reader.Read() Dim newItem As New ListItem() newItem.Text = reader("AllSites_Countries_Name") newItem.Value = reader("AllSites_Countries_Id") CType(LoginViewCart.FindControl("lstCountry"), DropDownList).Items.Add(newItem) Loop reader.Close() CType(LoginViewCart.FindControl("lstCountry"), DropDownList).SelectedValue = 182 Catch Err As Exception Response.Redirect("~/error-on-page/") MailSender.SendMailMessage("*********************", "", "", OrangeBoxSiteId.SiteName & " Error Catcher", "<p>Error in sub FillCountry</p><p>Error on page:" & HttpContext.Current.Request.Url.AbsoluteUri & "</p><p>Error details: " & Err.Message & "</p>") Response.Redirect("~/error-on-page/") Finally con.Close() End Try When the form is submitted an error occurs which says that the string "" cannot be converted to the datatype integer. For some reason the dropdownlist is posting "" rather than the value for the selected country.

• How to access and run field events from extension js?

  - by Dan Roberts

  I have an extension that helps in submitting forms automatically for a process at work. We are running into a problem with dual select boxes where one option is selected and then that selection changes another field's options. Since setting an option selected property to true doesn't trigger the field's onchange event I am trying to do so through code. The problem I've run into is that if I try to access or run functions on the field object from the extension, I get the error Error: uncaught exception: [Exception... "Component is not available" nsresult: "0x80040111 (NS_ERROR_NOT_AVAILABLE)" location: "JS frame :: chrome://webformsidebar/content/webformsidebar.js :: WebFormSidebar_FillProcess :: line 499" data: no] the line causing the error is... if (typeof thisField.onchange === 'function') The line right before it works just fine... thisField.options[t].selected=true; ...so I'm not sure why this is resulting in such an error. What surprises me most I guess is that checking for the existence of the function leads to an error. It feels like the problem is related to the code running in the context of the extension instead of the browser window document. If so, is there any way to call a function in the browser window context instead? Do I need to actually inject code into the page somehow? Any other ideas? Thanks

• How do i pass arbitary date format from C# to sql backend

  - by Jims

  I have a datetime field for the transaction date in the back end. So I am passing that date from front C#.net, in the below format: 2011-01-01 12:17:51.967 to do this I have written: presentation layer: string date = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss.fff", CultureInfo.InvariantCulture); PropertyClass prp=new PropertyClass(); Prp.TransDate=Convert.ToDateTime(date); PropertyClass structure: Public class property { private DateTime transdate; public DateTime TransDate { get { return transdate; } set { transdate = value; } } } From DAL layer passing the TransactionDate like this: Cmd.Parameters.AddWithValue("@TranSactionDate”, SqlDbType.DateTime).value=propertyobj.TransDate; While debugging from presntation layer: string date = DateTime.Now.ToString("yyyy-MM-dd HH:mm:ss.fff", CultureInfo.InvariantCulture); in this I am getting correct expected date format, but when debugs goes to this line Prp.TransDate=Convert.ToDateTime(date); again date format changing to 1/1/2011. But my backend sql datefield wants the date paramter 2011-01-01 12:17:51.967 in this format otherwise throwing exception invalid date format. Note: While passing date as string without converting to datetime getting exceptions like: System.Data.SqlTypes.SqlTypeException: SqlDateTime overflow. Must be between 1/1/1753 12:00:00 AM and 12/31/9999 11:59:59 PM. at System.Data.SqlTypes.SqlDateTime.FromTimeSpan(TimeSpan value) at System.Data.SqlTypes.SqlDateTime.FromDateTime(DateTime value) at System.Data.SqlTypes.SqlDateTime..ctor(DateTime value) at System.Data.SqlClient.MetaType.FromDateTime(DateTime dateTime, Byte cb) at System.Data.SqlClient.TdsParser.WriteValue(Object value, MetaType type, Byte scale, Int32 actualLength, Int32 encodingByteSize, Int32 offset, TdsParserStateObject stateObj) at System.Data.SqlClient.TdsParser.TdsExecuteRPC(_SqlRPC[] rpcArray, Int32 timeout, Boolean inSchema, SqlNotificationRequest notificationRequest, TdsParserStateObject stateObj, Boolean isCommandProc)

• InvalidOperationException when executing SqlCommand with transaction

  - by Serhat Özgel

  I have this code, running parallel in two separate threads. It works fine for a few times, but at some random point it throws InvalidOperationException: The transaction is either not associated with the current connection or has been completed. At the point of exception, I am looking inside the transaction with visual studio and verify its connection is set normally. Also command.Transaction._internalTransaction. _transactionState is set to Active and IsZombied property is set to false. This is a test application and I am using Thread.Sleep for creating longer transactions and causing overlaps. Why may the exception being thrown and what can I do about it? IDbCommand command = new SqlCommand("Select * From INFO"); IDbConnection connection = new SqlConnection(connectionString); command.Connection = connection; IDbTransaction transaction = null; try { connection.Open(); transaction = connection.BeginTransaction(); command.Transaction = transaction; command.ExecuteNonQuery(); // Sometimes throws exception Thread.Sleep(forawhile); // For overlapping transactions running in parallel transaction.Commit(); } catch (ApplicationException exception) { if (transaction != null) { transaction.Rollback(); } } finally { connection.Close(); }

• Pointer problem in C for char*

  - by egebilmuh

  Hi guys, i use pointer for holding name and research lab property. But when i print the existing Vertex ,when i print the vertex, i cant see so -called attributes properly. For example though real value of name is "lancelot" , i see it as wrong such as "asdasdasdasd" struct vertex { int value; char*name; char* researchLab; struct vertex *next; struct edge *list; }; void GRAPHinsertV(Graph G, int value,char*name,char*researchLab) { //create new Vertex. Vertex newV = malloc(sizeof newV); // set value of new variable to which belongs the person. newV->value = value; newV->name=name; newV->researchLab=researchLab; newV->next = G->head; newV->list = NULL; G->head = newV; G->V++; } /*** The method creates new person. **/ void createNewPerson(Graph G) { int id; char name[30]; char researchLab[30]; // get requeired variables. printf("Enter id of the person to be added.\n"); scanf("%d",&id); printf("Enter name of the person to be added.\n"); scanf("%s",name); printf("Enter researc lab of the person to be added\n"); scanf("%s",researchLab); // insert the people to the social network. GRAPHinsertV(G,id,name,researchLab); } void ListAllPeople(Graph G) { Vertex tmp; Edge list; for(tmp = G->head;tmp!=NULL;tmp=tmp->next) { fprintf(stdout,"V:%d\t%s\t%s\n",tmp->value,tmp->name,tmp->researchLab); } system("pause"); }

• Understanding Domain Driven Design

  - by Nihilist

  Hi I have been trying to understand DDD for few weeks now. Its very confusing. I dont understand how I organise my projects. I have lot of questions on UnitOfWork, Repository, Associations and the list goes on... Lets take a simple example. Album and Tracks. Album: AlbumId, Name, ListOf Tracks Tracks: TrackId, Name Question1: Should i expose Tracks as a IList/IEnumerabe property on Album ? If that how do i add an album ? OR should i expose a ReadOnlyCollection of Tracks and expose a AddTrack method? Question2: How do i load Tracks for Album [assuming lazy loading]? should the getter check for null and then use a repository to load the tracks if need be? Question3: How do we organise the assemblies. Like what does each assembly have? Model.dll - does it only have the domain entities? Where do the repositories go? Interfaces and implementations both. Can i define IAlbumRepository in Model.dll? Infrastructure.dll : what shold this have? Question4: Where is unit of work defined? How do repository and unit of work communicate? [ or should they ] for example. if i need to add multiple tracks to album, again should this be defined as AddTrack on Album OR should there a method in the repository? Regardless of where the method is, how do I implement unit of work here? Question5: Should the UI use Infrastructure..dll or should there be ServiceLayer? Do my quesitons make sense? Regards
