This will return true if the current culture is read from right to left.

How do I add two numbers without using ++ or + or any other arithmetic operator?

It was a question asked a long time ago in some campus interview. Anyway, today someone asked a question regarding some bit-manipulations, and in answers a beautiful quide *[Stanford bit twiddling*][1] was referred. I spend some time studying it and thought that there actually might be an answer to the question. I don&#39;t know, I could not find one. Does an answer exist?

How to add two numbers without using ++ or + or another arithmetic operator

I have a C# Windows application that I want to ensure will show up on a second monitor if the user moves it to one.  I need to save the main form&#39;s size, location and window state - which I&#39;ve already handled - but I also need to know which screen it was on when the user closed the application.

I&#39;m using the Screen class to determine the size of the current screen but I can&#39;t find anything on how to determine which screen the application was running on.

Edit: Thanks for the responses, everyone!  I wanted to determine which monitor the window was on so I could do proper bounds checking in case the user accidentally put the window outside the viewing area or changed the screen size such that the form wouldn&#39;t be completely visible anymore.

How do I determine which monitor my .NET Windows Forms program is running on?

I have looked around, but I have been unable to figure this out, some languages are read and written from right to left, instead of left to right.  It seems like a no-brainer to be able to get the text direction from the CultureInfo object somehow, but I have not seen it anywhere.  Am I missing something?

Is there any way to determine text direction from CultureInfo in asp.net?

I&#39;ve been running into some problems concerning a SqlTransaction I&#39;m using in my code. During my Googling I see many people using a using statement with a SqlTransaction.

What is the benefit and/or difference of using this type of statement with a SqlTransaction?

    using (SqlConnection cn = new SqlConnection())
    {
         using (SqlTransaction tr = cn.BeginTransaction())
         {
          //some code
          tr.Commit();
         }
    }

Currently my code looks like this:

    SqlConnection cn = new SqlConnection(ConfigurationManager.AppSettings[&quot;T3&quot;]);
    cn.Open();
    SqlTransaction tr = cn.BeginTransaction();
    
    try
    {
         //some code
         tr.Commit();
         cn.Close();
    }
    catch(Exception ex)
    {
          tr.Rollback();
          cn.Close();
          throw ex;
    }

What is the advantage of one way over the other?

Why use a using statement with a SqlTransaction?

For any arbitrary instance (collections of different objects, compositions, single objects, etc)

How can I determine its size in bytes?

(I&#39;ve currently got a collection of various objects and i&#39;m trying to determine the aggregated size of it)



EDIT:  Has someone written an extension method for Object that could do this?  That&#39;d be pretty neat imo.

How to disable a parent form when child form is active using c#?

How to disable the parent form when a child form is active?

I have two solutions in my workspace, say A and B.

Solution A is an older project which I finished coding some time ago.
In solution B, I need to use some classes from Solution A. To do so, I add a reference to the dll of one of the projects in solution A.

The problem is when I try to debug. I want to be able to step into A&#39;s code as well. Visual studio is not able to load the code for these classes (&quot;There is no source code available for the current location.&quot;) and I can only view the disassembly, which is not useful.

The only way I know to debug classes from solution A is by running solution B, detach all processes (in the Debug menu item) and attach the process from solution A.

However, this is very inconvenient and I can only debug A OR B at once.

Is there a way to allow stepping into the code of referenced dlls (for which I do have the source code)?


----------
**Solution:** My mistake was that I thought that a project can only be part of a single solution. In fact, a project can be part of any number of solutions.&lt;br/&gt;
When you need to reference the old project, you should simply add the project to the solution. This is done by right clicking the new solution in the Solution Explorer &gt; Add &gt; Existing Project.&lt;br/&gt;
Then, you&#39;ll be able to add the project reference. As others wrote, you should probably completely avoid using dll references to your own code (or other code you might need to change and debug).

A very good reference to how solutions should be designed can be found in [MSDN][1].

I&#39;d like to check if an object is a number so that `.ToString()` would result in a string containing digits and `+`,`-`,`.`

Is it possible by simple type checking in .net (like: `if (p is Number)`)?

Or Should I convert to string, then try parsing to double?


**Update:** To clarify my object is int, uint, float, double, and so on it isn&#39;t a string.
I&#39;m trying to make a function that would serialize any object to xml like this:
    
    &lt;string&gt;content&lt;/string&gt;

or

    &lt;numeric&gt;123.3&lt;/numeric&gt;

or raise an exception.

Does anyone know why a client-side javascript handler for asp:CheckBox needs to be an OnClick=&quot;&quot; attribute rather than an OnClientClick=&quot;&quot; attribute, as for asp:Button?

For example, this works: 

    &lt;asp:CheckBox runat=&quot;server&quot; OnClick=&quot;alert(this.checked);&quot; /&gt;

and this doesn&#39;t (no error):

    &lt;asp:CheckBox runat=&quot;server&quot; OnClientClick=&quot;alert(this.checked);&quot; /&gt;

but this works: 

    &lt;asp:Button runat=&quot;server&quot; OnClientClick=&quot;alert(&#39;Hi&#39;);&quot; /&gt;

and this doesn&#39;t (compile time error):

    &lt;asp:Button runat=&quot;server&quot; OnClick=&quot;alert(&#39;hi&#39;);&quot; /&gt;

(I know what Button.OnClick is for; I&#39;m wondering why CheckBox doesn&#39;t work the same way...)

I am looking for different techniques/tools you use to deploy an ASP.NET web application project (**NOT** ASP.NET web site) to production? 

I am particularly interested of the workflow happening between the time your Continuous Integration Build server drops the binaries at some location and the time the first user request hits these binaries.

1. Are you using some specific tools or just XCOPY? How is the application packaged (ZIP, MSI, ...)? 

2. When an application is deployed for the first time how do you setup the App Pool and Virtual Directory (do you create them manually or with some tool)? 

3. When a static resource changes (CSS, JS or image file) do you redeploy the whole application or only the modified resource? How about when an assembly/ASPX page changes?

4. Do you keep track of all deployed versions for a given application and in case something goes wrong do you have procedures of restoring the application to a previous known working state?

Feel free to complete the previous list.

---
And here&#39;s what we use to deploy our ASP.NET applications:

1. We add a [Web Deployment Project][1] to the solution and set it up to build the ASP.NET web application
2. We add a Setup Project (**NOT** Web Setup Project) to the solution and set it to take the output of the Web Deployment Project
3. We add a custom install action and in the OnInstall event we run a custom build .NET assembly that creates an App Pool and a Virtual Directory in IIS using [System.DirectoryServices.DirectoryEntry][2] (This task is performed only the first time an application is deployed). We support multiple Web Sites in IIS, Authentication for Virtual Directories and setting identities for App Pools.
4. We add a custom task in TFS to build the Setup Project (TFS does not support Setup Projects so we had to use devenv.exe to build the MSI)
5. The MSI is installed on the live server (if there&#39;s a previous version of the MSI it is first uninstalled)

Can ASP.Net routing (not MVC) be used to serve static files?

Say I want to route

    http://domain.tld/static/picture.jpg

to

    http://domain.tld/a/b/c/picture.jpg

and I want to do it dynamically in the sense that the rewritten URL is computed on the fly. I cannot set up a static route once and for all.

Anyway, I can create a route like this:

    routes.Add(
      &quot;StaticRoute&quot;, new Route(&quot;static/{file}&quot;, new FileRouteHandler())
    );

In the `FileRouteHandler.ProcessRequest` method I can rewrite the path from `/static/picture.jpg` to `/a/b/c/picture.jpg`. I then want to create a handler for static files. ASP.NET uses the `StaticFileHandler` for this purpose. Unfortunately, this class is internal. I have tried to create the handler using reflection and it actually works:

    Assembly assembly = Assembly.GetAssembly(typeof(IHttpHandler));
    Type staticFileHandlerType = assembly.GetType(&quot;System.Web.StaticFileHandler&quot;);
    ConstructorInfo constructorInfo = staticFileHandlerType.GetConstructor(BindingFlags.NonPublic | BindingFlags.Instance, null, Type.EmptyTypes, null);
    return (IHttpHandler) constructorInfo.Invoke(null);

But using internal types doesn&#39;t seem to be the proper solution. Another option is to implement my own `StaticFileHandler`, but doing so properly (supporting HTTP stuff like ranges and etags) is non-trivial.

How should I approach routing of static files in ASP.NET?

I am using the autocomplete feature of jQuery. When I try to retrieve the list of more then 17000 records (each won&#39;t have more than 10 char length), it&#39;s exceeding the length and throws the error:


&gt; Exception information: &lt;br/&gt;
    Exception type: InvalidOperationException &lt;br/&gt;
    Exception message: Error during serialization or deserialization using the JSON JavaScriptSerializer. The length of the string exceeds the value set on the maxJsonLength property.

Can I set an unlimited length for `maxJsonLength` in `web.config`? If not, what is the maximum length I can set?

What is the `*comment` parameter in:

    NSString *NSLocalizedString(NSString *key, NSString *comment)

If I do this:

    NSLocalizedString(@&quot;Hello_World_Key&quot;, @&quot;Hello World&quot;)

and have two versions of a Localizable.strings (English and Spanish), does each need the entry:

    English.lproj/Localization.strings: @&quot;Hello_World_Key&quot; = @&quot;Hello World&quot;;

    Spanish.lproj/Localization.strings: @&quot;Hello_World_Key&quot; = @&quot;Hola Mundo&quot;;

Isn&#39;t the English one redundant?

I need a french calendar and I can&#39;t understand the problem. I guess I&#39;m not using the regional options like it should be. But...

Here is my code :

    $(function() {
      $(&#39;#Date&#39;).datepicker({
          showMonthAfterYear: false,

What is the best place to set the Culture/UI Culture in an ASP.net MVC app

Currently I have a CultureController class which looks like this:

    public class CultureController : Controller
    {
        public ActionResult SetSpanishCulture()
        {
            HttpContext.Session[&quot;culture&quot;] = &quot;es-ES&quot;;
            return RedirectToAction(&quot;Index&quot;, &quot;Home&quot;);
        }

        public ActionResult SetFrenchCulture()
        {
            HttpContext.Session[&quot;culture&quot;] = &quot;fr-FR&quot;;
            return RedirectToAction(&quot;Index&quot;, &quot;Home&quot;);
        }
    }

and a hyperlink for each language on the homepage with a link such as this:

    &lt;li&gt;&lt;%= Html.ActionLink(&quot;French&quot;, &quot;SetFrenchCulture&quot;, &quot;Culture&quot;)%&gt;&lt;/li&gt;
    &lt;li&gt;&lt;%= Html.ActionLink(&quot;Spanish&quot;, &quot;SetSpanishCulture&quot;, &quot;Culture&quot;)%&gt;&lt;/li&gt;

which works fine but I am thinking there is a more appropriate way to do this.

I am reading the Culture using the following ActionFilter
http://www.iansuttle.com/blog/post/ASPNET-MVC-Action-Filter-for-Localized-Sites.aspx.  I am a bit of an MVC noob so am not confident I am setting this in the correct place.  I don&#39;t want to do it at the web.config level, it has to be based on a user&#39;s choice.  I also don&#39;t want to check their http-headers to get the culture from their browser settings.

Edit:

Just to be clear - I am not trying to decide whether to use session or not. I am happy with that bit.  What I am trying to work out is if it is best to do this in a Culture controller that has an action method for each Culture to be set, or is there is a better place in the MVC pipeline to do this?
