• reStructuredText tool support

  - by Chen Levy

  I love reStructuredText, however the tools that support it are scattered all over the Internet. The official tool list is incomplete and/or outdated, and can be updated only via commit privileges. For some time there was a comprehensive list at the Wikipedia reStructuredText page, but this apparently "may not meet the notability guideline for web content" and is scheduled for removal. So to put it in a question form: What tool support can one expect to find when working with reStructuredText, e.g. text editors, Wiki software, converters to and from reStructuredText etc.?

• Conditional OrderBy

  - by jeriley

  So, right now I've got a number of columns the user can sort by (Name, County, Active) and that's easy but messy. Looks something like this... Select Case e.SortExpression Case "Name" If (isDescending) Then resultsList.OrderByDescending(Function(a) a.Name).ToList() Else resultsList.OrderBy(Function(a) a.Name).ToList() End If Case "County" ... and so on what I would LIKE to do, is something more ... graceful, like this Private Function SortThatList(ByVal listOfStuff As List(Of Stuff), ByVal isDescending As Boolean, ByVal expression As Func(Of Stuff)) As List(Of Stuff) If (isDescending) Then Return listOfStuff.OrderByDescending(expression) Else : Return listOfStuff.OrderBy(expression) End If End Function but it doesn't like the datatype (Of TKey) ... I've tired Func(Of stuff, boolean) (got something in c# that works nicely like that) but can't seem to get this one to do what I want. Ideas? What's the magic syntax?

• jQuery jPicker > Assign color of jPicker from a text link (not from jPicker)

  - by Scott B

  I've got a list of frequently used hex colors that I'd like to list under my jPicker bound input text field and I'd like to figure out how to change the value of the jPicker active color without opening the jPicker color selector palette. I've managed to create a function that updates the input field thats bound to the jPicker, but the colors of the background and picker.gif do not update. I'd like to force the background colors to update as if the color was selected from jPicker itself. Here's my code for the activation link... <span onclick=doColor(1,'cc9900')>cc9900</span> And here's the js handler function doColor(el, color) { if(el){$('#theme_header_color').attr('value', color);} else{$('#theme_sidebar_color').attr('value', color);} }

• CakePHP: find neighbors, order on 'name' or 'order'

  - by Brelsnok

  Hi, I have a list of ordered items, ordered according to the int field order. I'm creating a gallery in CakePHP 1.2 that has a prev and next button and those should link to the previous and next item according to their ordering, not according to their id. In order to get this result I've included the 'order' parameter to the find function, and populated it with 'Item.order'=>'DESC'. Still the result is an id ordered list. My question is: what do I do wrong? My controller: $this->Item->id = 16; $neighbours = $this->Item->find('neighbors', array('order'=>array('Item.order'=>'DESC'), 'fields'=>array('id','name')));

• What is the C# equivalent of this Excel VBA code for Shapes?

  - by code4life

  This is the VBA code for an Excel template, which I'm trying to convert to C# in a VSTO project I'm working on. By the way, it's a VSTO add-in: Dim addedShapes() As Variant ReDim addedShapes(1) addedShapes(1) = aBracket.Name ReDim Preserve addedShapes(UBound(addedShapes) + 1) addedShapes(UBound(addedShapes)) = "unique2" Set tmpShape = Me.Shapes.Range(addedShapes).Group At this point, I'm stumped by the addedShapes(), not sure what this is all about. Update: Matti mentioned that addedShapes() represents a variant array in VBA. So now I'm wondering what the contents of addedShapes() should be. Would this be the correct way to call the Shapes.Range() call in C#? List<string> addedShapes = new List<string>(); ... Shape tmpShape = worksheet.Shapes.get_Range (addedShapes.Cast<object>().ToArray()).Group(); I'd appreciate anyone who's worked with VBA and C# willing to make a comment on my question & problem!

• Linux Kernel - Refreshing VFS Dentry Cache

  - by Mike D

  I wrote a system call that opens a directory and gets the file object and the dentry struct. Im trying to list all entries including entries in subdirectories using the list_for_each() macro. The problem is its only displaying whats currently in the dentry cache. If I open the directory with nautilus then rerun the system call, all the entries are listed. Is there a way to check the exact list of entries or refresh the cache? f = s_open(tpath); fle = fget(f); d = fle->f_path.dentry; list_for_each ( position , &d->d_subdirs ) { dtmp = list_entry(position, struct dentry, d_u.d_child); ... } sys_close(f);

• SSRS: Master-detail report with two datasources

  - by Svish

  I have two local data sources that I can push into the report. Works no problem. But how do I set up the report? One data source contains a list of employees, and info about them. The other contains a bunch of working hours for each employee. I would like to use a table for the list of employees, and then have another table for the working hours beneath each employee (with their working hours). Is this even possible? Do I have to use a Sub-Report? Would I have to merge them into one datasource? =/

• Microsoft Charting Histogram Zero With Line

  - by Brownman98

  I am currently developing an application that uses chart control to create a histogram. The histogram displays data correctly however I would like to center the data. Right now the Min and Max are automatically set. I would like the graph to always force its to be displayed symmetrically. Here is an example of what I'm trying to accomplish. Basically I would like it to look like a normal distribution graph. Does anyone know how I can do the the following: Get the graph to be displayed symmetrically? Always show a zero line. Here is the aspx markup. <asp:Chart ID="ChartHistogram" runat="server" Height="200" Width="300"> <Series> <asp:Series Name="SeriesDataHistogram" ChartType="RangeColumn" Color="#4d5b6e" BorderColor="#ffffff" BorderDashStyle="NotSet"> </asp:Series> </Series> <ChartAreas> <asp:ChartArea Name="ChartAreaMain" BorderColor="#CCCCCC"> <AxisX TitleFont="Arial, 7pt" LabelAutoFitMaxFontSize="7"> <MajorGrid LineColor="#FFFFFF" Interval="5" /> <LabelStyle Format="P1" /> </AxisX> <AxisY Title="Frequency" TitleFont="Arial, 7pt" LabelAutoFitMaxFontSize="7"> <MajorGrid LineColor="#FFFFFF" /> </AxisY> </asp:ChartArea> </ChartAreas> </asp:Chart> Here is the code behind private void DrawHistogram(List<ReturnDataObject> list) { foreach (ReturnDataObject r in list) this.ChartHistogram.Series["SeriesDataHistogram"].Points.AddY(r.ReturnAmount); // HistogramChartHelper is a helper class found in the samples Utilities folder. HistogramChartHelper histogramHelper = new HistogramChartHelper(); // Show the percent frequency on the right Y axis. histogramHelper.ShowPercentOnSecondaryYAxis = false; // Create histogram series histogramHelper.CreateHistogram(ChartHistogram, "SeriesDataHistogram", "Histogram"); } Thanks for any help.

• RenderAction not finding action method in current controller in current area

  - by Andrew Davey

  I'm creating an ASP.NET MVC 2 (RTM) project that uses areas. The Index action of the Home controller of one area needs to use RenderAction to generate a sub-section of the page. The action called is also defined in the same Home controller. So the call should just be: <% Html.RenderAction("List") %> However, I get an exception: A public action method 'List' was not found on controller 'RareBridge.Web.Areas.Events.Controllers.HomeController'. Note that I'm not in the "Events" area! I'm in a completely different area. If I remove the "Events" home controller, then the exception still occurs but names a different controller (still not the one I want it to call). I've also tried providing the controller name and area to the RenderAction method, but the same exception occurs. What is going on here? BTW: I am using Autofac as my IoC container

• Problem in Tabindex

  - by i2ijeya

  I have around 50-60 components and some of the fields are readonly. Now I want to set the tab index only for the fields that are read/write. Now the problem for me is, some of the components will be added according to the selection in my dropdown list box. Those components that are newly populated also contains some read only text boxes. The thing is, some of the options in the dropdown list may contain or may not contain components. So how could I Give the tabindex appropriately. eg : textbox1 : tabindex="1" textbox2 : tabindex="2" dropdown : tabindex="3" textbox for dropdown : tabindex="?" textbox : tabindex="?"

• UIPickerView with NSDictionary

  - by Dave

  I am a .NET programmer and new to Objective C. I am trying to make a UIPickerView which acts like a .NET dropdownlist. User sees the list of text and selects one and the selected value (which is the ID) is used in code. I have been browsing for almost half a day trying to figure this out. I could add a regular PickerView with list of strings, picker view with mulitple components and picker view with dependent components none of which seems to answer my query. Please help.

• What parts of .NET require administrative priviliges to be executed?

  - by Ruben Steins

  Which parts of the framework require a user to be more than a Standard User? The reason I'm asking is because I'm trying to compile a list of possible issues with our existing applications when migrating to Windows 7. Now, I can think of a few things myself: Writing to Eventlog Writing to Registry Keys outside of Current_User scope Getting an Environment variable etc... I really would like a more complete list and so far I've not come across a decent resource in which all this stuff is listed. Note that I'm not looking for ways of elevating the priviliges for the exsiting apps (which can be done by using a manifes), I'm simply idenitifying actions in code that might cause issues.

• C# Inhieriting DataContract Derived Types

  - by dsjohnston

  I've given a fair read through msdn:datacontracts and I cannot find a out why the following does not work. So what is wrong here? Why isn't ExtendedCanadianAddress recognized by the datacontract serializer? Type 'XYZ.ExtendedCanadianAddress' with data contract name 'CanadianAddress:http://tempuri.org/Common/Types' is not expected. Add any types not known statically to the list of known types - for example, by using the KnownTypeAttribute attribute or by adding them to the list of known types passed to DataContractSerializer. Given: namespace ABC { [KnownType(typeof(Address))] public abstract class Z { //stuff //method that adds all types() in namespace to self } [KnownType(typeof(CanadianAddress))] [DataContact(Name = "Address", Namespace = "http://tempuri.org/Types")] public class Address : Z {} [DataContract(Name = "CanadianAddress", Namespace = "http://tempuri.org/Types")] public class CanadianAddress : Address {} } namespace XYZ { [KnownType(typeof(ExtendedCanadianAddress)) [DataContact(Name = "Address", Namespace = "http://tempuri.org/Types")] public class ExtendedAddress : Address { //this serializes just fine } [DataContact(Name = "CanadianAddress", Namespace = "http://tempuri.org/Types")] public class ExtendedCanadianAddress : CanadianAddress { //will NOT serialize } }

• Can I split an IEnumerable into two by a boolean criteria without two queries?

  - by SFun28

  Folks, Is it possible to split an IEnumerable into two IEnumerables using LINQ and only a single query/linq statement? In this way, I would avoid iterating through the IEnumerable twice. For example, is it possible to combine the last two statements below so allValues is only traversed once? IEnumerable<MyObj> allValues = ... List<MyObj> trues = allValues.Where( val => val.SomeProp ).ToList(); List<MyObj> falses = allValues.Where( val => !val.SomeProp ).ToList();

• jQuery get select option text

  - by Paolo Bergantino

  Alright, say I have this: <select id='list'> <option value='1'>Option A</option> <option value='2'>Option B</option> <option value='3'>Option C</option> </select> What would the selector look like if I wanted to get "Option B" when I have the value '2'. Please note that this is not asking how to get the selected text value, but just any one of them, whether selected or not, depending on the value attribute. I tried: $("#list[value='2']").text(); But it is not working.

• jQueryUI Ajax.NET Postback Bug

  - by nigative

  Hi, I have this ASP.NET page with ASP.NET UpdatePanel and jQueryUI droppable and sortable components. The page works fine in all browsers, but doesn't in Internet Explorer (IE8 tested). After I try to call ASP.NET AJAX event (by pressing my asp.net button inside the UpdatePanel) my sortable list stops working properly inside IE browser and the browser throws the following error: Message: Unspecified error. Line: 145 Char: 186 Code: 0 URI: http://code.jquery.com/jquery-1.4.2.min.js I found out that the problem is caused by the code on line 66: $("#droppable").droppable(); If I comment it out, the sortable list works fine after ajax postbacks. But it doesn't make sense. Does anyone know what could be wrong? Thanks. P.S. I am using jQueryUI 1.8.1 and jQuery 1.4.2

• Good Async pattern for sequential WebClient requests

  - by Omar Shahine

  Most of the code I've written in .NET to make REST calls have been synchronous. Since Silverlight on Windows Phone only supports Async WebClient and HttpWebRequest calls, I was wondering what a good async pattern is for a Class that exposes methods that make REST calls. For example, I have an app that needs to do the following. Login and get token Using token from #1, get a list of albums Using token from #1 get a list of categories etc my class exposes a few methods: Login() GetAlbums() GetCategories() since each method needs to call WebClient using Async calls what I need to do is essentially block calling Login till it returns so that I can call GetAlbums(). What is a good way to go about this in my class that exposes those methods?

• Re-setting CSS code for form buttons

  - by WebDevHobo

  I used a CSS reset to reset some commonly-used items. The code is this: html, body, div, h1, h2, h3, h4, ul, ol, li, form, input, fieldset, textarea { margin: 0; padding: 0; border: 0; font-size: 100%; } ul {list-style: none outside none;} img, fieldset {border: 0;} h1, h2, h3, h4 {font-weight: normal;} em {font-style: italic;} strong {font-weight: bold;} I know there's YUI and Meyer's reset, but I use this one. Now, the problem I'm experiencing is that I can't get the submit buttons to look normally again. I could ofcourse remove the input from the list and be done with it, but I'd like to know how to get it back, since I might need that in the future.

• Repeater and add columns to header and itemtemplate on page load

  - by sdmiller

  I haven't used repeaters for much more than showing data from a datatable. I am building a grid that that shows a list of users and columns of roles that the user has been assigned, shown with checkboxes (shown with true/false below but pretent they are checkboxes). ex. |Rep Name|Caller|Closer|Manager|SuperUser| |Bob |True |true | false | false | |Tom |false |false |True | True | Basically using it for roles management. However the roles may change later on so I want to load the roles(headers and items) dynamically into the repeater. I am not sure how to do this or if it is even possible. I figure you grab a list of current role possibilities and load them into the headertemplate but I am not sure how to match those with the itemtemplate and how to create checkboxes and place them in the itemtemplate. Sorry if it is a rudementary question.... I appreciate any advice!
