  • jQuery version of YAHOO.lang (isUndefined, isNull, isString etc.)

    - by Chris S
    Does anyone know of a jQuery plugin that has 'helpers' or extensions like those found in the YAHOO.lang namespace? I have in mind functions such as: isNull isDefined isString isFunction I would also appreciate the same kind of thing for strings and arrays, such as Contains, StartsWith (I know these are easy to write, I'm just looking for a plugin that encompasses them all). It's not in the YAHOO.lang namespace but also form related extensions- determining a radiobox's value (from the one checked), a form element's type in a friendly name. Specifically a plugin with fluent API rather than selector based such as $("input[@type=radio][@checked]") Again I'm aware they're easy to implement but I don't want to reinvent the wheel.

  • Adding file names to an array list in java

    - by Chris G
    Hi I am currently needing to load the contents of a folders filenames to an arraylist I have but I am unsure as how to do this. To put it into perspective I have a folder with One.txt, Two.txt, Three.txt etc. I want to be able to load this list into an arraylist so that if I was to check the arraylist its contents would be : arraylist[0] = One arraylist[1] = Two arraylist[3] = Three If anyone could give me any insight into this it would be much appreciated.

  • How do I get certain code to execute before every single controller action in ASP.NET MVC 2?

    - by Chris
    I want to check some things about the state of the session, the user agent, etc, and possibly take action and return a special view BEFORE a controller method gets a chance to execute. For example: Most common: User requests Home/Index System checks to make sure x != 0. x does not equal zero, so the Home/Index controller executes like normal. But, sometimes: User requests Home/Index System checks to make sure x != 0. x DOES equal zero. The user must be notified and the requested controller action cannot be allowed to execute. I think this involves the use of ActionFilters. But I have read about them and I don't understand if I can preempt the controller method and return a view before it executes. I am sure I could execute code before the controller method runs, but how do I keep it from running in some instances and return a custom view, or direct to a different controller method?

  • Re-ordering a collection of UIView's based on their CGPoint

    - by Chris
    Hi all, I have a NSMutableArray that holds a collection of UIViewControllers Amongst other properties and methods an instance of each of the viewControllers are placed in a parent view The user will place these objects individually when desired to. So essentially I use - (void)addSubview:(UIView *)view when a new view is added to the parent view controller. Because the UI is isometric it's made things a tad more complicated What I am trying to do is re-order the views based on their co-ordinate position, so items higher up the parent UIView frame is indexed lower then views lower in the parent UIview frame. And items that are on the left side of the view are positioned at a higher index to those on the right I think the solution may have to do with re-ordering the NSMutableArray but how can I compare the CGpoints? Do I need to compare the x and y separately?

  • Importing a spreadsheet, but having trouble.

    - by Chris Phelps
    I have a form that allows a user to import a spreadsheet. This spreadsheet is generally static when it comes to column headers, but now the users want to be able to include an optional column (called Notes). My code crashes when I try to read the column from the spreadsheet if it doesn't exist. Dim objCommand As New OleDbCommand() objCommand = ExcelConnection() 'function that opens spreadsheet and returns objCommand Dim reader As OleDbDataReader reader = objCommand.ExecuteReader() While reader.Read() Dim Employee As String = Convert.ToString(reader("User")) Dim SerialNUM As String = Convert.ToString(reader("serialno")) **Dim Notes As String = Convert.ToString(reader("notes"))** If the spreadsheet contains a Notes column, all goes well. If not, crash. How can I check to see if the Notes column exists in the spreadsheet to avoid the crash?

  • How does Access 2007's moveNext/moveFirst/, etc., feature work?

    - by Chris M
    I'm not an Access expert, but am an SQL expert. I inherited an Access front-end referencing a SQL 2005 database that worked OK for about 5000 records, but is failing miserably for 800k records... Behind the scenes in the SQL profiler & activity manager I see some kind of Access query like: SELECT "MS1"."id" FROM "dbo"."customer" "MS1" ORDER BY "MS1"."id" The MS prefix doesn't appear in any Access code I can see. I'm suspicious of the built-in Access navigation code: DoCmd.GoToRecord , , acNext The GoToRecord has AcRecord constant, which includes things like acFirst, acLast, acNext, acPrevious and acGoTo. What does it mean in a database context to move to the "next" record? This particular table uses an identity column as the PK, so is it internally grabbing all the IDs and then moving to the one that is the next highest??? If so, how would it work if a table was comprised of three different fields for the PK? Or am I on the wrong track, and something else in Access is calling that statement? Unfortunately I see a ton of prepared statements in the profiler. THanks!

  • "this" in function parameter

    - by chris
    Looking at some code examples for HtmlHelpers, and I see declarations that look like: public static string HelperName(this HtmlHelper htmlHelper, ...more regular params ) I can't remember seeing this type of construct any where else - can someone explain the purpose of the "this"? I thought that by declaring something public static meant that the class did not need to be instantiated - so what is "this" in this case?

  • Force column order, Excel data table

    - by Chris
    I have a Excel Workbook that I use as a report template. I change the datasource on each pivot and datatable in a C# app. When I change the datatable datasource it tweeks the columns. Is there a way to force the column order? private void RefreshRawData(string dataSource, string connection) { xl._Worksheet ws = (xl._Worksheet)xlTemplate.Worksheets["Raw Data"]; xl.ListObject table = ws.ListObjects["Table_ExternalData_1"]; xl.QueryTable qt = table.QueryTable; qt.CommandText = dataSource; qt.Connection = GetExcelConnectionString((string)qt.Connection); qt.BackgroundQuery = false; qt.Refresh(m); Marshal.ReleaseComObject(ws); Marshal.ReleaseComObject(table); Marshal.ReleaseComObject(qt); ws = null; table = null; qt = null; }

  • How do you compare music data

    - by Chris
    i want to write an app to rename sort and organize my music library (mp3's, wav's, flac's). I wanted to take a portion of the song, say the first minutes, and compare that to a database and then retrieve the song name and tag information. I have heard that you can do this with last.fm but a look through their api info didn't help. My question is, what is this called so i can google it better? nothing i am trying is helping much. This would be similar to the shazam android app. My prefered language would be java, so i can run it on a few operating systems easier, but that might be subject to change depending on how i can do it. Thanks

  • How can I tell if a <script> tag with a given src attribute is present on the page in ASP.net?

    - by Chris McCall
    Like the title says, I'm trying to find out if I need to include a script library that my ASP.net UserControl needs to work. I don't want to include it multiple times per page, but I want my control to be able to be used multiple times on the same page. How can I, in the codebehind of my control, check to see if a given <script/> tag is present? This is .Net 2.0, no LINQ.

  • bind parent child listview asp.net

    - by Chris
    I'm trying to display two linq query results in a prent and child listview. I have the following code which gets the correct values to populate the listviews but when I nest the child listview inside the parent list view, I get an error saying "The name 'ListView2' does not exist in the current context". I presume I need to bind the two listviews in the code behind but my problem is I don't know how or the best way to do this. I have read a couple of posts on similar problems but my lack of knowledge on the subject doesn't make it clear to me. Please can somebody help me figure this out? It's the final piece of code I need to complete. Many thanks in advance. Here is my .aspx code: <asp:ListView ID="ListView1" runat="server"> <EmptyDataTemplate>No data was returned.</EmptyDataTemplate> <ItemSeparatorTemplate><br /></ItemSeparatorTemplate> <ItemTemplate> <li> <asp:Label ID="LabelID" runat="server" Text='<%# Eval("RecordID") %>'></asp:Label><br /> <asp:Label ID="LabelNumber" runat="server" Text='<%# Eval("CartID") %>'></asp:Label><br /> <asp:Label ID="LabelName" runat="server" Text='<%# Eval("Number") %>'></asp:Label><br /> <asp:Label ID="LabelDestination" runat="server" Text='<%# Eval("Destination") %>'></asp:Label><br /> <asp:Label ID="LabelPkgName" runat="server" Text='<%# Eval("PkgName") %>'></asp:Label> <li> <!-- LIST VIEW FOR FEATURES --> <asp:ListView ID="ListView2" runat="server"> <EmptyDataTemplate>No data was returned.</EmptyDataTemplate> <ItemSeparatorTemplate><br /></ItemSeparatorTemplate> <ItemTemplate> <li> <asp:Label ID="LabelFeatureName" runat="server" Text='<%# Eval("FeatureName") %>'></asp:Label><br /> <asp:Label ID="LabelFeatureSetUp" runat="server" Text='<%# Eval("FeatureSetUp") %>'></asp:Label><br /> <asp:Label ID="LabelFeatureMonthly" runat="server" Text='<%# Eval("FeatureMonthly") %>'></asp:Label><br /> </li> </ItemTemplate> <LayoutTemplate> <ul ID="itemPlaceholderContainer" runat="server" style=""> <li runat="server" id="itemPlaceholder" /> </ul> </LayoutTemplate> </asp:ListView> <!-- LIST VIEW FOR FEATURES [END] --> </li> </li> </ItemTemplate> <LayoutTemplate> <ul ID="itemPlaceholderContainer" runat="server" style=""> <li runat="server" id="itemPlaceholder" /> </ul> </LayoutTemplate> </asp:ListView> Here is my code behind: MyShoppingCart userShoppingCart = new MyShoppingCart(); string cartID = userShoppingCart.GetShoppingCartId(); using (ShoppingCartv2Entities db = new ShoppingCartv2Entities()) { var CartNumber = from c in db.NewViews where c.CartID == cartID select c; foreach (NewView item in CartNumber) { ListView1.DataSource = CartNumber; ListView1.DataBind(); } var CartFeature = from f in db.NewViews join o in db.NumberFeatureViews on f.RecordID equals o.RecordID where f.CartID == cartID select new { o.FeatureName, o.FeatureSetUp, o.FeatureMonthly }; foreach (var x in CartFeature) { ListView2.DataSource = CartFeature; ListView2.DataBind(); } }

    I correctly inserted a javascript file into the wordPress admin with : wp_enqueue_script() I know that the script is loading. I tested it with an alert(). I then found that I am unable to access the DOM. When I tried : document.getElementsByTagName('body')[0].addEventListener('load', function() {}); This error was: Uncaught TypeError: Cannot call method 'addEventListener' of undefined This is the first time I have used 'settings api' or inserted scripts into the WordPress admin.

  • Use JQuery to target unwrapped text inside a div

    - by Chris
    I'm trying to find a way to wrap just the inner text of an element, I don't want to target any other inner dom elements. For example. <ul> <li class="this-one"> this is my item <ul> <li> this is a sub element </li> </ul> </li> </ul> I want to use jQuery to do this. <ul> <li class="this-one"> <div class="tree-item-text">this is my item</div> <ul> <li> <div class="tree-item-text">this is a sub element</div> </li> </ul> </li> </ul> A little background is I need to make an in-house tree structure ui element, So I'm using the UL structure to represent this. But I don't want developers to have to do any special formatting to use the widget. update: I just wanted to add the purpose of this is I want to add a click listener to be able to expand the elements under the li, However, since those elements are within the li the click listener will activate even when clicking on the children, So I want to attach it to the text instead, to do this the text needs to be targetable, which is why I want to wrap it in a div of it's own. So far I've come up with wrapping all the inner elements of the li in a div and then moving all inner dom elements back to the original parent. But this code is pretty heavy for something that might be much simpler and not require so much DOM manipulation. EDIT: Want to share the first pseudo alternative I came up with but I think it is very tasking for what I want to accomplish. var innerTextThing = $("ul.tree ul").parents("li").wrapInner("<div class='tree-node-text'>"); $(innerTextThing.find(".tree-node-text")).each(function(){ $(this).after($(this).children("ul")); }); Answered: I ended up doing the following, FYI i only have to worry about FF and IE compatibility so it's untested in other browsers. //this will wrap all li textNodes in a div so we can target them. $(that).find("li").contents() .filter(function () { return this.nodeType == 3; }).each(function () { if ( //these are for IE and FF compatibility (this.textContent != undefined && this.textContent.trim() != "") || (this.innerText != undefined && this.innerText.trim() != "") ) { $(this).wrap("<div class='tree-node-text'>"); } });

  • How do I organize C# classes that inherit from one another, but also have properties that inherit from one another?

    - by Chris
    I have an application that has a concept of a Venue, a place where events happen. A Venue is owned by a Company and has many VenueParts. So, it looks like this: public abstract class Venue { public int Id { get; set; } public string Name { get; set; } public virtual Company Company { get; set; } public virtual ICollection<VenuePart> VenueParts { get; set; } } A Venue can be a GolfCourseVenue, which is a Venue that has a Slope and a specific kind of VenuePart called a HoleVenuePart: public class GolfCourseVenue { public string Slope { get; set; } public virtual ICollection<HoleVenuePart> Holes { get; set; } } In the future, there may also be other kinds of Venues that all inherit from Venue. They might add their own fields, and will always have VenueParts of their own specific type. My declarations above seem wrong, because now I have a GolfCourseVenue with two collections, when really it should just have the one. I can't override it, because the type is different, right? When I run reports, I would like to refer to the classes generically, where I just spit out Venues and VenueParts. But, when I render forms and such, I would like to be specific. I have a lot of relationships like this and am wondering what I am doing wrong. For example, I have an Order that has OrderItems, but also specific kinds of Orders that have specific kinds of OrderItems.

  • How do I validate that a list box is not empty (client side)

    - by chris
    I'm working with ASP.NET 3.5. I have a list box that users must add items to (I've written the code for this). My requirement is that at least one item must be added to the listbox or they cannot submit the form. I have several other validators on the page and they all write to a ValidationSummary control. I would like this listbox validation to write to the Validation Summary control as well. Any help is greatly appreciated. Thank you.

  • How to convert "0" and "1" to false and true

    - by Chris
    I have a method which is connecting to a database via Odbc. The stored procedure which I'm calling has a return value which from the database side is a 'Char'. Right now I'm grabbing that return value as a string and using it in a simple if statement. I really don't like the idea of comparing a string like this when only two values can come back from the database, 0 and 1. OdbcCommand fetchCommand = new OdbcCommand(storedProc, conn); fetchCommand.CommandType = CommandType.StoredProcedure; fetchCommand.Parameters.AddWithValue("@column ", myCustomParameter); fetchCommand.Parameters.Add("@myReturnValue", OdbcType.Char, 1). Direction = ParameterDirection.Output; fetchCommand.ExecuteNonQuery(); string returnValue = fetchCommand.Parameters["@myReturnValue"].Value.ToString(); if (returnValue == "1") { return true; } What would be the proper way to handle this situation. I've tried 'Convert.ToBoolean()' which seemed like the obvious answer but I ran into the 'String was not recognized as a valid Boolean. ' exception being thrown. Am I missing something here, or is there another way to make '1' and '0' act like true and false? Thanks!

  • How can I make a workspace-folder level build script visible in the Eclipse Project Explorer?

    - by Chris
    I have a number of interdependent projects in an Eclipse workspace. Eclipse manages dependencies between them within the IDE but I'm starting work on a master build script that will sit in the folder about all the projects (the workspace folder). I haven't decided on if I will use Maven, Gradle or Ant/Ivy tet, but my question is, is there a way so that I can see a build script in the workspace folder in the Project/Package explorer? Currently it only shows me projects, but assuming I decide on an Ant build, I want to be able to see the main build.xml file in this window. I've played around with settings to no avail. Is it possible? If not, should I just set up an external run configuration instead?

  • Import data from an SSRS report via SSIS package

    - by Chris
    First, I ask that you not ask 'why.' In the famous words of Tennyson "Ours is not to reason why. Ours is but to do and die." It's one of those, "This is what you have, deal with it." situations. The source data comes from SSRS report. The goal is to load the data into a database via SSIS. The hopeful goal is to avoid human intervention in having to download the SSRS report into Excel or CSV. There will be complex SSIS processing from there on out. Any suggestions are humbly appreciated.

  • Ruby - Passing Blocks To Methods

    - by Chris Bunch
    I'm trying to do Ruby password input with the Highline gem and since I have the user input the password twice, I'd like to eliminate the duplication on the blocks I'm passing in. For example, a simple version of what I'm doing right now is: new_pass = ask("Enter your new password: ") { |prompt| prompt.echo = false } verify_pass = ask("Enter again to verify: ") { |prompt| prompt.echo = false } And what I'd like to change it to is something like this: foo = Proc.new { |prompt| prompt.echo = false } new_pass = ask("Enter your new password: ") foo verify_pass = ask("Enter again to verify: ") foo Which unfortunately doesn't work. What's the correct way to do this?

  • Consuming a HTTPS Web Service in .Net 3.5 Web Project

    I'm trying to consume a webservice that ONLY runs on HTTPS but using the "add service" method in VS or using the WSDL to generate a code file leaves me with a web service that states its http... <wsdl:service name="OGServ"> <wsdl:documentation xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/">XML Web Services element of OGServ Gateway</wsdl:documentation> <wsdl:port name="OGServSoap" binding="tns:OGServSoap"> <soap:address location="http://ogserv.domain.co.uk/ogwsrv/og.asmx" /> </wsdl:port> <wsdl:port name="OGServSoap12" binding="tns:OGServSoap12"> <soap12:address location="http://ogserv.domain.co.uk/ogwsrv/og.asmx" /> </wsdl:port> </wsdl:service> Would this be the reason that even when I change the app.config (generated by the add-service) endpoint address to https it says it was expecting HTTP?
