  • Show Visual Studio's Source Control Merge Wizard programmatically

    - by Mike
    Hi, I'm developing a Work item Custom Control and I need to use the standard VS's Merge Wizard for items in source control from my code to allow to user choose the target branch, resolve conflicts etc. I'm pretty sure it's possible in some way (even through the reflection), but I just can't find the proper class in any of VS client assemblies (Microsoft.TeamFoundation.VersionControl.Controls.dll, Microsoft.TeamFoundation.VersionControl.Client.dll). Any help will be appreciated. Best regards, Mike

  • Partials in Liquid

    - by kostia
    Hello, We're trying to rewrite our current views from ERb to Liquid and we got following problem: we have a lot of render(:partial => '/path/to/partial') in our code, but we found absolutely no instructions how to render partials in Liquid. The only one solution we found was with help of render_to_string but it's just to ugly to be true. Thanx!

  • How to declare and implement a COM interface on C# that inherits from another COM interface?

    - by Carlos Loth
    I'm trying to understand what is the correct why to implement COM interfaces from C# code. It is straightforward when the interface doesn't inherit from other base interface. Like this one: [ComImport, Guid("2047E320-F2A9-11CE-AE65-08002B2E1262"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)] public interface IShellFolderViewCB { long MessageSFVCB(uint uMsg, int wParam, int lParam); } However things start to become weired when I need to implement an interface that inherits from other COM interfaces. For example, if I implement the IPersistFolder2 interface which inherits from IPersistFolder which inherits from IPersist as I usually on C# code: [ComImport, Guid("0000010c-0000-0000-C000-000000000046"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)] public interface IPersist { void GetClassID([Out] out Guid classID); } [ComImport, Guid("000214EA-0000-0000-C000-000000000046"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)] public interface IPersistFolder : IPersist { void Initialize([In] IntPtr pidl); } [ComImport, Guid("1AC3D9F0-175C-11d1-95BE-00609797EA4F"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)] public interface IPersistFolder2 : IPersistFolder { void GetCurFolder([Out] out IntPtr ppidl); } The operating system is not able to call the methods on my object implementation. When I'm debugging I can see the constructor of my IPersistFolder2 implementation is called many times, however the interface methods I've implemented aren't called. I'm implementing the IPersistFolder2 as follows: [Guid("A4603CDB-EC86-4E40-80FE-25D5F5FA467D")] public class PersistFolder: IPersistFolder2 { void IPersistFolder2.GetClassID(ref Guid classID) { ... } void IPersistFolder2.Initialize(IntPtr pidl) { ... } void IPersistFolder2.GetCurFolder(out IntPtr ppidl) { ... } } What seems strange is when I declare the COM interface imports as follow, it works: [ComImport, Guid("0000010c-0000-0000-C000-000000000046"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)] internal interface IPersist { void GetClassID([Out] out Guid classID); } [ComImport, Guid("000214EA-0000-0000-C000-000000000046"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)] internal interface IPersistFolder : IPersist { new void GetClassID([Out] out Guid classID); void Initialize([In] IntPtr pidl); } [ComImport, Guid("1AC3D9F0-175C-11d1-95BE-00609797EA4F"), InterfaceType(ComInterfaceType.InterfaceIsIUnknown)] internal interface IPersistFolder2 : IPersistFolder { new void GetClassID([Out] out Guid classID); new void Initialize([In] IntPtr pidl); void GetCurFolder([Out] out IntPtr ppidl); } I don't know why it works when I declare the COM interfaces that way (hidding the base interface methods using new). Maybe it is related to the way IUnknown works. Does anyone know what is the correct way of implementing COM interfaces in C# that inherits from other COM interfaces and why?

  • How do I redirect a page in php

    - by user225269
    I'm having difficulties in the making the logout code for php to work. When I click on the logout button, it will go back to the home page, but when I click on the back button in the browser. I can still access the previous page, wherein the user must be logged on to access it. So I'm thinking of redirecting to the login page when the user clicks on the back button on the browser. This is my code, in the home page(where in no user is logged in yet. This page is being called by a logout link on the user page. <? session_start(); session_destroy(); ?> <table width="300" border="0" align="center" cellpadding="0" cellspacing="1" bgcolor="#CCCCCC"> <tr> <form name="form1" method="post" action="checklogin.php"> <td> <table width="100%" border="0" cellpadding="3" cellspacing="1" bgcolor="#FFFFFF"> <tr> <td colspan="3"><strong>Member Login </strong></td> </tr> <tr> <td width="78">Username</td> <td width="6">:</td> <td width="294"><input name="myusername" type="text" id="myusername"></td> </tr> <tr> <td>Password</td> <td>:</td> <td><input name="mypassword" type="text" id="mypassword"></td> </tr> <tr> <td>&nbsp;</td> <td>&nbsp;</td> <td><input type="submit" name="Submit" value="Login"></td> </tr> </table> </td> </form> </tr> </table>

  • Silverlight Marching Ants Image Selection

    - by Ben Herila
    (Silverlight 3) Is there a pre-existing (preferably free, even better if open source) method (either a control or source code) for dragging a "marching ants" style selection on an image in a ScrollViewer or on a Canvas, similar to how it's done in image editing software? Even better if the resulting selection box has adjustment handles.

  • Fortran bus error on mac

    - by SteveJ
    The following Fortran code is giving me a bus error on my Mac but no errors when I run it on my Linux machine: PROGRAM TINY WRITE(UNIT=*, FMT=*) 'Hello, world!' END My understanding is that a bus error occurs when the program attempts to access impossible memory but I do not understand where such an attempt has been made in this program. My MacBook has GCC 4.4.0 and my Linux machine has GCC 4.3.2. Any ideas as to why this error occurs?

  • JavaScript: How to get the instance name of an object

    - by Quandary
    I use the below code to write code to query a web method in a specified interval. now in the this.Poll function I have to do this.tmo = setTimeout(this.strInstanceName + ".Poll()", this.iInterval); instead of this.tmo = setTimeout(this.Poll(), this.iInterval); because IE looses the this object after setTimeout So I have to pass the class it's instance name: var objPoll = new cPoll("objPoll"); How can I get the instance name without passing it as parameter ?

  • Using cascade in NHibernate

    - by Tyler
    I have two classes, call them Monkey and Banana, with a one-to-many bidirectional relationship. Monkey monkey = new Monkey(); Banana banana = new Banana(); monkey.Bananas.Add(banana); banana.Monkey = monkey; hibernateService.Save(banana); When I run that chunk of code, I want both monkey and banana to be persisted. However, it's only persisting both when I explicitly save the monkey and not vice versa. Initially, this made sense since only my Monkey.hbm.xml had a mapping with cascade="all". <set name="Bananas" inverse="true" cascade="all"> <key column="Id"/> <one-to-many class="Banana"/> </set> I figured I just needed to add the following to my Banana.hbm.xml file: <many-to-one name="Monkey" column="Id" cascade="all" /> Unfortunately, this resulted in a Parameter index is out of range error when I tried to run the snippet of code. I investigated this error and found this post, but I still don't see what I'm doing wrong. I have the relationship mapped once on each side as far as I can tell. For full disclosure, here are the two mapping files: Monkey.hbm.xml <class name="Monkey" table="monkies" lazy="true"> <id name="Id"> <generator class="increment" /> </id> <property name="Name" /> <set name="Bananas" inverse="true" cascade="all"> <key column="Id"/> <one-to-many class="Banana"/> </set> </class> Banana.hbm.xml <class name="Banana" table="bananas" lazy="true"> <id name="Id"> <generator class="increment" /> </id> <property name="Name" /> <many-to-one name="Monkey" column="Id" cascade="all" /> </class>

  • Good alternative to Eregi() in PHP

    - by Click Upvote
    I often find myself doing quick checks like this: if (! eregi('.php',$fileName)) $filename.='.php'; But sadly eregi() is going to be deprecated in PHP 6, which means all of my code that uses it will be rendered useless :(. Is there another function that behaves exactly the same way as eregi()? I don't know anything about reg exps and don't want to learn, so preg_match() etc won't work for me.

  • Routed Command Question

    - by Andrew
    I'd like to implement a custom command to capture a Backspace key gesture inside of a textbox, but I don't know how. I wrote a test program in order to understand what's going on, but the behaviour of the program is rather confusing. Basically, I just need to be able to handle the Backspace key gesture via wpf commands while keyboard focus is in the textbox, and without disrupting the normal behaviour of the Backspace key within the textbox. Here's the xaml for the main window and the corresponding code-behind, too (note that I created a second command for the Enter key, just to compare its behaviour to that of the Backspace key): <Window x:Class="WpfApplication1.Window1" xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation" xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml" Title="Window1" Height="300" Width="300"> <Grid> <TextBox Margin="44,54,44,128" Name="textBox1" /> </Grid> </Window> And here's the corresponding code-behind: using System.Windows; using System.Windows.Input; namespace WpfApplication1 { /// <summary> /// Interaction logic for EntryListView.xaml /// </summary> public partial class Window1 : Window { public static RoutedCommand EnterCommand = new RoutedCommand(); public static RoutedCommand BackspaceCommand = new RoutedCommand(); public Window1() { InitializeComponent(); CommandBinding cb1 = new CommandBinding(EnterCommand, EnterExecuted, EnterCanExecute); CommandBinding cb2 = new CommandBinding(BackspaceCommand, BackspaceExecuted, BackspaceCanExecute); this.CommandBindings.Add(cb1); this.CommandBindings.Add(cb2); KeyGesture kg1 = new KeyGesture(Key.Enter); KeyGesture kg2 = new KeyGesture(Key.Back); InputBinding ib1 = new InputBinding(EnterCommand, kg1); InputBinding ib2 = new InputBinding(BackspaceCommand, kg2); this.InputBindings.Add(ib1); this.InputBindings.Add(ib2); } #region Command Handlers private void EnterCanExecute(object sender, CanExecuteRoutedEventArgs e) { MessageBox.Show("Inside EnterCanExecute Method."); e.CanExecute = true; } private void EnterExecuted(object sender, ExecutedRoutedEventArgs e) { MessageBox.Show("Inside EnterExecuted Method."); e.Handled = true; } private void BackspaceCanExecute(object sender, CanExecuteRoutedEventArgs e) { MessageBox.Show("Inside BackspaceCanExecute Method."); e.Handled = true; } private void BackspaceExecuted(object sender, ExecutedRoutedEventArgs e) { MessageBox.Show("Inside BackspaceExecuted Method."); e.Handled = true; } #endregion Command Handlers } } Any help would be very much appreciated.

  • CodeDOM: Adding DebuggerStepThroughAttribute to property

    I know how to add a DebuggerStepThroughAttribute to a method or a constructor, usually you add it to the CustomAttributes collection of a code member. But I don't see a way to do this for the setter and getter of a C# property, because neither of them provides this collection where you add the attributes. Does anyone have a clue?
