You should use [`Or`][1], not `||`:

    Condition=&quot;&#39;$(Configuration)&#39;==&#39;Debug&#39; Or &#39;$(Configuration)&#39;==&#39;Release&#39;&quot;

I have an activity that has the following set as theme:

    android:theme=&quot;@android:style/Theme.Dialog&quot;

However, there is a title bar in the activity-dialog that appears, that uses up the little available space that I have. How can I remove it?

I have following problem. I want to make some graphics in c# windows form. 
I want to read bitmap to my program and after it write some text on this bitmap. In the end I want this picture load to pictureBox. And it&#39;s my question. How can I do it?

example, how must it work:

    Bitmap a = new Bitmap(@&quot;path\picture.bmp&quot;);
    a.makeTransparent();
    // ? a.writeText(&quot;some text&quot;, positionX, positionY);
    pictuteBox1.Image = a;

Is it possible do to?

Here&#39;s a snippet from my csproj file:


    &lt;ProjectReference Include=&quot;..\program_data\program_data.csproj&quot; Condition=&quot;&#39;$(Configuration)&#39;==&#39;Debug&#39;&quot;&gt;

          &lt;Name&gt;program_data&lt;/Name&gt;
    &lt;/ProjectReference&gt;

What I&#39;d like to do is include `program_data.dll` for **multiple** build configurations, for example, both Release and Debug.

I tried doing the following

    Condition=&quot;&#39;$(Configuration)&#39;==&#39;Debug&#39; || &#39;$(Configuration)&#39;==&#39;Release&#39;&quot;

but Visual Studio chokes on this. 

Is there a way I can do this, or must I have a separate `&lt;ProjectReference&gt;` for each build config?

I am trying to make a very basic REST call to my MVC 3 API and the parameters I pass in are not binding to the action method.

**Client**
    
    var request = new RestRequest(Method.POST);

    request.Resource = &quot;Api/Score&quot;;
    request.RequestFormat = DataFormat.Json;
            
    request.AddBody(request.JsonSerializer.Serialize(new { A = &quot;foo&quot;, B = &quot;bar&quot; }));
            
    RestResponse response = client.Execute(request);
    Console.WriteLine(response.Content);

**Server**

    public class ScoreInputModel
    {
       public string A { get; set; }
       public string B { get; set; }
    }

    // Api/Score
    public JsonResult Score(ScoreInputModel input)
    {
       // input.A and input.B are empty when called with RestSharp
    }

Am I missing something here?

When I want a specific menu link to be active at a given page, I&#39;m using this approach in Razor:

On the master layout I have these checks:

    var active = ViewBag.Active;
    const string ACTIVE_CLASS = &quot;current&quot;;
    
    if (active == &quot;home&quot;)
    {
    	ViewBag.ActiveHome = ACTIVE_CLASS;
    }
    if (active == &quot;products&quot;)
    {
    	ViewBag.ActiveProducts = ACTIVE_CLASS;
    }

etc.

The html menu on the master layout:

    &lt;ul&gt;
    &lt;li class=&quot;@ViewBag.ActiveHome&quot;&gt;&lt;a href=&quot;/&quot;&gt;Home&lt;/a&gt;&lt;/li&gt;
    &lt;li class=&quot;@ViewBag.ActiveProducts&quot;&gt;&lt;a href=&quot;@Url.Action(&quot;index&quot;, &quot;products&quot;)&quot;&gt;Products&lt;/a&gt;&lt;/li&gt;
    &lt;/ul&gt;

When specifying which layout page to use on a different view:

    @{
    	ViewBag.Active = &quot;home&quot;;
    	Layout = &quot;~/Views/Shared/_Layout.cshtml&quot;;
    }

Is there a better approach to sepcify active links, than the one I&#39;m currently using?

I am trying to return a view not issue a redirect to the user based on certain errors that could occur from my application, I want to handle the errors + log them inside my base controller, I do not want the error to propagate up to my Global.asax - Application_Error() method as I want this method to handle any other errors inside my app e.g. user enters a bogus URL, has anyone found a way around this?

NOTE: I have left my commented code as I had a workaround for some issues, this also shows I have multiple exceptions to possible handle...

EDIT: If I issue a RedirectToAction within this OnException override everything works as expected, but I only want to return the view and no redirection...

My base controller method is:


        protected override void OnException(ExceptionContext filterContext)
        {
            //dont interfere if the exception is already handled
            if (filterContext.ExceptionHandled)
                return;

            //let the next request know what went wrong
            filterContext.Controller.TempData[&quot;exception&quot;] = filterContext.Exception;

            //log exception
            _logging.Error(User.Identity.Name, ExceptionHelper.BuildWebExceptionMessage(filterContext.Exception));


            //set up redirect to my global error handler
            //if (filterContext.Exception.GetType() == typeof(NoAccessException))
            //    filterContext.Result = View(new RouteValueDictionary
            //    (new { area = &quot;&quot;, controller = &quot;Error&quot;, action = &quot;PublicError&quot; }));

            //else {
            //Only return view, no need for redirection
            filterContext.Result = View(new RouteValueDictionary
            (new { area = &quot;&quot;, controller = &quot;Error&quot;, action = &quot;NoAccess&quot; }));
            //}
            //advise subsequent exception filters not to interfere and stop
            // asp.net from showing yellow screen of death
            filterContext.ExceptionHandled = true;

            //erase any output already generated
            filterContext.HttpContext.Response.Clear();

            //base.OnException(filterContext);
        }

This method should handle any other errors that could appear in my app, I do not want the errors above being handled inside my Application_Error()

    protected void Application_Error()
            {
    
                Exception exception = Server.GetLastError();
                // Log the exception.
    
                var logger = Container.Get&lt;ILoggingService&gt;();
                logger.Error(User.Identity.Name, ExceptionHelper.BuildWebExceptionMessage(exception));
    
                Response.Clear();
    
                HttpException httpException = exception as HttpException;
    
                RouteData routeData = new RouteData();
                routeData.Values.Add(&quot;controller&quot;, &quot;Error&quot;);
    
                //if (httpException == null)
                //{
                routeData.Values.Add(&quot;action&quot;, &quot;PublicError&quot;);
                //}
                //else //It&#39;s an Http Exception, Let&#39;s handle it.

                //        case 500:

I have added a custom section called `secureAppSettings` to my web.config file:
```xml
&lt;configuration&gt;

    &lt;add key=&quot;userPassword&quot; value=&quot;password&quot;/&gt;
  &lt;/secureAppSettings&gt;  
&lt;/configuration&gt;
```
`secureAppSettings` is decrypted and has two keys inside it.

Now in my code, I tried to access the keys like this:

    string userName = System.Configuration.ConfigurationManager.secureAppSettings[&quot;userName&quot;];
    string userPassword = System.Configuration.ConfigurationManager.secureAppSettings[&quot;userPassword&quot;];

But `null` is returning for these fields.

How can I get the field values?

Can anyone explain how to create a header file in C with a simple example from beginning to end.


Creating your own header file in C

I&#39;m having trouble understanding the ruleset regarding PHP relative include paths.  If I run file A.PHP- and file A.PHP includes file B.PHP which includes file C.PHP, should the relative path to C.PHP be in relation to the location of B.PHP, or to the location of A.PHP?  That is, does it matter which *file* the include is called from, or only what the current working directory is- and what determines the current working directory?





Are PHP include paths relative to the file or the calling code?

I have a main directory `A` with two sub directories `B` and `C`.

Directory `B` contains a header file `structures.c`:
                        
    #ifndef __STRUCTURES_H
    #define __STRUCTURES_H
    typedef struct __stud_ent__
    {
        char name[20];
        int roll_num;
    }stud;
    #endif


Directory `C` contains `main.c` code:

    #include&lt;stdio.h&gt;
    #include&lt;stdlib.h&gt;
    #include &lt;structures.h&gt;
    int main()
    {
        stud *value;
        value = malloc(sizeof(stud));
        free (value);
        printf(&quot;working \n&quot;);
        return 0;
    }

But I get an error:

&lt;!-- language: none --&gt; 

    main.c:3:24: error: structures.h: No such file or directory
    main.c: In function ‘main’:
    main.c:6: error: ‘stud’ undeclared (first use in this function)
    main.c:6: error: (Each undeclared identifier is reported only once
    main.c:6: error: for each function it appears in.)
    main.c:6: error: ‘value’ undeclared (first use in this function)

What is the correct way to include the `structures.h` file into `main.c`?

Does a Python equivalent to the Ruby `||=` operator (&quot;set the variable if the variable is not set&quot;) exist?

Example in Ruby :


     variable_not_set ||= &#39;bla bla&#39;
     variable_not_set == &#39;bla bla&#39;

     variable_set = &#39;pi pi&#39;
     variable_set ||= &#39;bla bla&#39;
     variable_set == &#39;pi pi&#39;

Python conditional assignment operator

I&#39;ve had a colleague that told me he once worked for a company that had as a policy to never have conditionals (&quot;if&quot; and &quot;switch&quot; statements) in the code and that they let all the decisions in the code be done using polymorphism and (I&#39;m guessing) some other OO principles.

I *sort of* understand the reasoning behind this, of having code that is more DRY and easier to update, but I&#39;m looking for a more in-depth explanation of this concept. Or maybe it&#39;s part of a more general design approach.

If anyone has any resources for this or would be willing to explain or even have some more terms related to this I can use to find more answers I&#39;d be much obliged.

I found [one question on SO][1] that was kind of related but I&#39;m unfamiliar with C++ so I don&#39;t understand too much of the answers there.

(I&#39;m no OO guru btw but I can manage)

I&#39;m most proficient in PHP, and after that Python so I&#39;d prefer info that uses those languages.

Update: I&#39;ll ask my colleague for more info on what he meant exactly.

Update 2015: after some more years of experience in programming I see now that the aim of this policy was probably to prevent programmers from adding functionality in a haphazard way by just adding conditionals (if statements) in certain places. A better way to extend software is to use the [&quot;Open/Closed principle&quot;][2] where software is extended by using inheritance and polymorphism. I strongly doubt whether the policy was super strict on all conditionals as it&#39;s kinda hard to go completely without them.

I have a for loop over an array. What I want to do is test for a certain condition in the loop and skip to the next iteration if true:

        If (Schedule(i, 1) &lt; ReferenceDate) Then
            PrevCouponIndex = i

        DF = Application.Run(&quot;SomeFunction&quot;....)
        PV = PV + (DF * Coupon / CouponFrequency)
    Next
    
I Know I can do:

     If (Schedule(i, 1) &lt; ReferenceDate) Then Continue For

but I want to be able to record the last value of i in the PrevCouponIndex variable. 

Any ideas?

Thanks

How do I use properly CASE..WHEN in MySQL

Usually a C# project has a .csproj file associated with it. What is that file for? What data does it contain? 

What does the .csproj file do?

I&#39;m packaging example code for an SDK distribution.  In the distribution, the relative path from code to the SDK assemblies is different from the build machine.  For example:

**Distribution**

    csharp/bin/assembly.dll
    example/ex1/ex1.csproj

**Build Machine**

    foo/sdk/csharp/bin/assembly.dll
    bar/baz/quux/ex1/ex1.csproj

Assume that I can&#39;t move anything.  Is there a way I can instruct `ex1.csproj` to look in both

`../../csharp/bin/` **and** `../../../../foo/sdk/csharp/bin/` for `assembly.dll`?

In C++ I&#39;d put the dependency path in a standalone property sheet and distribute a different version with the SDK.  But C# doesn&#39;t have property sheets, and I don&#39;t want to maintain two versions of the full project.

I&#39;ve seen [this question][1] which states that I can&#39;t use multiple `&lt;HintPath&gt;` tags, so I&#39;m looking for another way to approximate the same behavior.

.csproj multiple hint paths for an assembly

I am using VS2010 and I tried to add a few assemblies from local hard disk to my C# project through file reference. Peeking into the `csproj` file, I found sometimes the file reference appears as

    &lt;Reference Include=&quot;name&quot;&gt;

However sometimes it appears as

    &lt;Reference Include=&quot;name, Version=xxx, Culture=neutral, 
                                              processorArchitecture=MSIL&quot;&gt;

What could cause the difference?

---

Inspired by k3b&#39;s answer, I did another test. I created a new class library project.

 1. Add a file reference. The initial value of *Specific Version* in *Properties* pane is *False*. The `csproj` file look like

        &lt;Reference Include=&quot;Name&quot;&gt;
          &lt;HintPath&gt;...&lt;/HintPath&gt;
        &lt;/Reference&gt;

 2. Change *Specific Version* in *Properties* pane to *True*. VS adds version in the `Include` attribute.

        &lt;Reference Include=&quot;Name, Version=...&quot;&gt;
          &lt;HintPath&gt;...&lt;/HintPath&gt;
        &lt;/Reference&gt;

 3. Change *Specific Version* in *Properties* pane to *False* again. VS adds a child element `SpecificVersion`.

        &lt;Reference Include=&quot;Name, Version=...&quot;&gt;
          &lt;HintPath&gt;...&lt;/HintPath&gt;
          &lt;SpecificVersion&gt;False&lt;/SpecificVersion&gt;
        &lt;/Reference&gt;

So it seems that the rule is:

 - When *Version* is present in *Include* attribute and there is no `SpecificVersion` child element, the file assembly is configured to be Specific Version
 - The `SpecificVersion` child element is only appended with value *False*.

One thing I still do not understand:

 - For my new test project, if I remove the file reference and add it back again, it goes back to format in point 1, which is the default.
 - For my existing project, if I remove the file reference and add it back again, I get back format in point 3. Although it also means that Specific Version is not used, I am wondering why it does not go back to format in point 1.

Understanding a csproj assembly reference

In a C# solution, I added a existing project.  
After that, Visual Studio has added the following entry in other .csproj files:

    &lt;ItemGroup&gt;
        &lt;Service Include=&quot;{B4F97281-0DBD-4835-9ED8-7DFB966E87FF}&quot; /&gt;
    &lt;/ItemGroup&gt;

What&#39;s this for?  
Can I delete it?

What is &quot;Service Include&quot; in a csproj file for?

When adding certain NuGet packges to a project, sometimes a strange item appears in the first property group of the .csproj file.

    &lt;PropertyGroup&gt;
      ...
      &lt;NuGetPackageImportStamp&gt;3d051ef3&lt;/NuGetPackageImportStamp&gt;
    &lt;/PropertyGroup&gt;

The stamp is different every time, and doesn&#39;t appear to be sequential.

I can&#39;t find any reference to `&lt;NuGetPackageImportStamp&gt;` in the NuGet documentation.  What is it for and how does it work?  Is it necessary?

One package that appears to add this every time is [StyleCop.MSBuild][1], at least with the current 4.7.49 version.  Simply add that package to a new project and you&#39;ll see this mystery item appear in your project file.

What is NuGetPackageImportStamp for?

is there a way in Visual Studio to use a custom Configuration like &quot;#if DEBUG&quot;

I need a &quot;#if OFFLINE&quot; as my Build-Config&#39;s name is &quot;Offline&quot; (only for further debug-purposes too)...

Thanks!
