In my current project we have many parts where we have something as follows:
var request = new ThingRequest {someId = };
ThingResponse response = dispatcher.Get<ThingResponse>(request);
Where dispatcher fetches a class with the name ThingRequestHandler that handles the actual logic.
public class ThingRequestHandler : RequestHandler<ThingRequest, ThingResponse>
This system is great for keeping it SOLID but I'm having trouble navigating easily.
Currently I use R# to goto class and -as I now the class name to follow convention- manually type the class name. This usually works but makes my head jump from thinking about the problem to thinking about a class name.
I would love to be able to navigate to my ThingRequestHandler from my dispatcher.Get line with one keystroke or click.
Is there a way Visual studio 2012, R# or any other plugin or macro would help me do this?
In R# 8+ they made a loads of improvements and especially to the navigation. They introduced CamelHumps which could be very useful in your case. For example you could navigate to ThingRequestHandler just by typing trh.

When creating a WatchKit (WatchOS) Interface controller in the storyboard designer/editor, I cannot set it's class to something that is not itself type WKInterfaceController nor an immediate derived child of WKInterfaceController.
Basically in the hope of abstraction and better code reuse, better design overall, I would like to be able to use classes that are how to say, a more distant relative of their base WKInterfaceController
Basically right now it seems that your stuck using the storyboard designer to make a new WatchOS project. And using the storyboard designer you only have the option to select the WKInterfaceController class:
public partial class WKInterfaceController
or one that directly inherits from it:
public partial class ChildInterfaceController : WKInterfaceController
but nothing else such as:
public partial class GrandChildInterfaceController: ChildInterfaceController
So is there any way to do this that doesn't risk the chance of getting corrupted when you reenter the storyboard designer at some point?
Note: I've already asked if it is possible to avoid using a storyboard all together, but that has gone unanswered so I'm assuming no.
For clarity I'm talking about this dialog for "class":
I'm using this NetResource class to send files to a network drive and it looks like this:
[StructLayout(LayoutKind.Sequential)]
public class NetResource
{
public ResourceScope Scope;
public ResourceType ResourceType;
public ResourceDisplayType DisplayType;
public int Usage;
public string LocalName;
public string RemoteName;
public string Comment;
public string Provider;
}
Now it's very important that the order of these fields stay the same, as hinted on by the StructLayout attribute.
However, when someone would run a resharper cleanup, resharper decides to move the fields around and that would break the code.
Is there any way of telling rehsarper to not mess with it? I feel like if I can't do that, someone is going to eventually break the code and have no idea where to look.
But a mediocre solution to that I think would be to create a unittest that can check if there layout is as expected.
Edit: I've seen this answer, but it is outdated and requires resharper settings to be updated. I will also not be guaranteed that coworkers use this resharper setting. I'm looking for a way to add it in the code, just like you can do // ReSharper disable once InconsistentNaming
I see a couple of solutions here:
You might mark the class with NoReorderAttribute from the JetBrains.Annotations (there are several ways to add them to a project). Then ReSharper will stop reordering members inside the marked code entity.
It is mostly about already mentioned answer, I will show you how to get the same things in last ReSharper builds. All you need is to add "System.Runtime.InteropServices.StructLayoutAttribute" to "Non-reorderable types" pattern in ReSharper | Options | Code Editing | C# | File Layout.
Step 1:
Step 2:
Step 3:
Step 4:
Step 5:
To make sure your colleagues use the same settings in ReSharper, save this change to the Solution team shared layer (Save To at the bottom of the Options dialog). Then if any of your colleagues opens the solution, ReSharper will automatically use the setting from this layer with no additional actions required.
Getting started with xCode 4.6.3 and I'm running into a hiccup.
I've built a simple app using the UIWebView to display a local HTML file and it's contents. I used that to debug any issues with the HTML and/or image displays and I'm all set.
Now I need to recreate that within a larger project I've built with storyboards for all my navigations between multiple view controllers. My issue comes when I'm trying to control-click drag from the WebView into the ViewController.h code below the #interface like many tutorials show, and that worked fine within my smaller single view controller app. It won't do it. I know I'm missing something obvious here. Am I going to have the set up these screens (I have multiple ones to do this same way) as separate xib files and add them into my main project?
Thanks for any help and clarification.

You can create a class called for example myWebViewController and in Interface builder add a UIWebView to it. The control+drag to the header file will work.
Every time you want a UIViewController that has a browser in it, define its class as myWebViewController in Interface Builder.
Try not to repeat code. If you see UIViewControllers or any other UIView...that do the same thing, you can group them into a class that you use over and over.
I'm writing a VS2012 add-in, adding a command to Build Explorer context menu (see related question). The command gets added to 2 different context menus:
Build Explorer
Team Explorer, Builds page, My Builds section
When my one callback is called, how do I know which of these it is?
I tried get the focused control (using P/Invoke as this question suggests). However, it gets me a Tabs container for (1), and null for (2). I could try to cast the control to the tabbed container, but that sounds pretty bad...
Any better alternative?
My new/other idea - it is similar to yours:
You should try to monitor which window was activated lastly.
If you create an eventhandler for your command, then you may be able to check which window is active when your command fired. A simple evenent handler for a command:
void cmdEvents_BeforeExecute( string guid, int ID, object customIn, object customOut, ref bool cancelDefault )
{
Window2 teamExplorer = _applicationObject.Windows.Item("Team Explorer") as Window2;
if (_applicationObject.ActiveWindow.Caption == teamExplorer.Caption)
{
//You are called from Team Explorer
}
else
{
//Somewhere else
}
}
And the way you can subscribe:
static _dispCommandEvents_BeforeExecuteEventHandler _myHandler;
static CommandEvents _cmdEvents;
public void OnConnection(...)
{
Command command = ...; // Init your command
int ID = command.ID;
string GUID = command.Guid;
CommandEvents _cmdEvents = _applicationObject.Events.get_CommandEvents(GUID, ID);
_myHandler = new _dispCommandEvents_BeforeExecuteEventHandler(cmdEvents_BeforeExecute);
_cmdEvents.BeforeExecute += _myHandler;
}
You may find a better way to identify the window(s) by GUID. You should keep at least _cmdEvents as static because when it will be desroyed, your event handler could vanish (least for internal commands).
In OnDisconnection you should unsubscribe.
Reworked by the comment, and founded links:
As the menu item is shown every place it seems there is no way to distinct between them from an Add-In, you should add two command and distinct them by their context.
The way instead of converting the Add-In to a VS-Package MZ-Tools HOWTO: Controlling the state of command in a Visual Studio add-in, try MZ-Tools HOWTO: Use the IVsMonitorSelection ... you can also get it from an Add-In.
But:
Neither the AddNamedCommand nor the QueryStatus methods honor the
invisible state: the button that must be invisible ...
remains disabled rather than invisible.
I think this makes it impossible to do it from an Add-In on a suitable way, but maybe you can check the contexts.
Other way you could get further, if you try to migrate your command/menu into a VSPackage and create a custom UIContext for the menu items or find a suitable predefined one. I have no access to a Studio enhanced with Build Explorer so I can't try it.
The following discussion is about custom contexts for vs-packages:
http://davedewinter.com/2008/04/05/dynamic-menu-commands-in-visual-studio-packages-part-3/
Sadly the links are broken from the post, and I can't reach Part 1. and Part 2. which is about the discussion of the problem from the beginning.
But there is no guarantee you can create a context which suits you.
Only context ID I found for Team Explorer is the guidTeamProjectCmdUIContext.
It is placed at vsshilds.h in Visual Studio 2010 SDK, vsshell*.h are also contain several others.
MSDN: Vsct files to define command, menus, ect. from packages.
Condition attribute for items:
http://msdn.microsoft.com/en-us/library/bb491718.aspx
http://msdn.microsoft.com/en-us/library/bb166515.aspx
MSDN: VisibilityItem element for commands and toolbars.
VisibilityItem element determines the static visibility of commands and toolbars.
... After the VSPackage is loaded, Visual Studio expects command visibility to be determined by the VSPackage rather than the VisibilityItem.
And finally about predefined Context Guids:

** New EDIT **
so what I'm trying to do is this.
I want the to add new form elements generated by my module on the product view of the following url
http://magento.example.com/catalog/product/view/id/46
ultimately these elements will be determined to show up by a related table in my module
I expected that if I extended Mage_Catalog_Block_Product_View in my module as shown below I would be able to create a block in the product form that would contain such form fields, only if he are in the related table in my module
so I created a test.phtml file in
app/design/frontend/default/default/templates/<module>/test.phtml
then as you can see in my the View.php file described bellow I built the block and displayed it in the product view.
It did appear but 5 times too many. from the answers below this is normal so that answers the question as to why the it shows up five times but leaves the question what is the proper way to proceecd since this plan is not going to work
** End New Edit **
in my module I call _prepareLayout() and it does this 5 times when i pull up the page
here's my code
in
/app/code/local/Namespace/Module/Product/Veiw.php
class <Namespace>_<module>_Block_Product_View extends Mage_Catalog_Block_Product_View {
protected function _toHtml() {
return parent::_toHtml();
}
public function _prepareLayout() {
$block = $this->getLayout()->createBlock(
'Mage_Core_Block_Template',
'my_block_name_here',
array('template' => '<module>/test.phtml')
);
if ($block){
$this->getLayout()->getBlock('content')->insert($block)->toHtml();
}else{
echo "no block";
}
return parent::_prepareLayout();
}
}
NOTE:
I just noticed this also takes away the price availability qty and add to cart button. which is also a problem
EDIT
First I want to thank you all for your answers. Second i want to give you more context
the reason for choosing to do this in the module is that I don't want the block to show up on every product . What i have is a table of what I'll call custom options containing properties of the product sort of like hair color height weight etc and depending on what set of properties are attached to the product (if any) will depend on what html content will show up on the page.
so in one case it my get a drop down menu and in another case it may get an input box. the other very important piece is that this must be setup so that I can give the end result out as a module that can be installed and not worrry that it won't show up if someone upgrades there magento
that said does it still make sense to do this all in the xml file ?
It seems to me that your code is overriding a core Magento module in order to achieve what could be easily done in the layout xml configuration. I would strongly recommend the follwing:
Use the built-in configuration mechanisms (e.g. layout xml - read Alan's excellent tutorial here) instead of writing code whenever possible.
Don't override the core code
if you must change the behaviour of the core code, use an Observer rather than Rewrite/Override
if you absolutely must Override, always call parent::whatever()
For example, if you create a <module>.xml layout file in your theme (app/design/frontend/default/<theme>/layout), you could use the following code:
<catalog_product_view>
<reference name="content">
<block type="module/block" name"my_block_name_here" template="module/test.phtml"/>
</reference>
</catalog_product_view>
You would then need to use a getChildHtml('my_block_name_here'); call within your phtml to position the block.
So unless there is other functionality happening inside your _prepareLayout, there's no need to override the core, or even to override the default catalog.xml.
EDIT (small edit above)
So now in your Block (I would recommend that you call it Namespace_Module_Block_Product_Customattributes or something like that), you are not overriding the core Product_View block, but merely processing your logic for what html widgets to use to render your custom attributes. Leave the rest of the tier prices, add to cart, other generic product block code, etc to Magento to work out.
If you are worried about the upgrade path for your module's users, you should definitely NOT be overriding core code. Use the configuration approach and very selectively introduce code that "plays nice" with the system rather than try to boss it around with overrides.
I took a look at a stock Magento install of CE 1.4.1, and unmodified the _prepareLayout method is called six times when loading the URL
http://magento.example.com/catalog/product/view/id/46
That's because the class is instantiated six times. So that's the correct behavior.
As for the vanishing element, I can'y say for sure, but your override to _prepareLayout doesn't appear to either
Do the same things as Mage_Catalog_Block_Product_View::_prepareLayout
Call parent::_prepareLayout();
When you override a class in a Magento you're replacing an existing class with your own. If you change a method, you're responsible for that old code being run.
It's not clear what you're trying to accomplish here. You should consider breaking your problem down into smaller problems, and then posting one (or more) "I tried X, expected Y, and got Z" type questions. As written no one's going to be able to answer your question.
