In the string.xml file I use the following tag 
 
    &lt;color name=&quot;mycolor1&quot;&gt;#F5DC49&lt;/color&gt;

If I use 
     
     textview1.setTextColor(Color.CYAN);

it works, but

     textview1.setTextColor(R.color.mycolor1);

is not working.

How can I use the color defined in the XML file?

How do you reference an constants with EL on a JSP page?

I have an interface `Addresses` with a constant named `URL`. I know I can reference it with a scriplet by going: `&lt;%=Addresses.URL%&gt;`, but how do I do this using EL?

I have Java 1.6 and Tomcat 5.5 installed on my system.

But Tomcat 5.5 accesses Java 1.5 and hence as the outcome I get the error `Bad version number in .class file` while executing java code with JSP.

How can I change the Tomcat version to Java 1.6?

**UPDATE**

I tried changing the JVM that the tomcat5w.exe is pointing to the version 1.6 and now I am out of the `Bad version in .class file` error. But now, I get the following error.

Whenever I print something inside the servlet and call it by the webbrowser, it returns a new page containing that text. Is there a way to print the text in the current page using Ajax?

&lt;!-- End of automatically inserted text --&gt;


I have to secure the passwords of my web site users.  What I did was use MD5 &lt;s&gt;encryption&lt;/s&gt; hashing in server side. But the problem is the passwords remain in plain text until it arrives at the server, which means that the password can be captured using traffic monitoring. So what I want is to use a client side password encryption/hashing mechanism and send the encrypted/hashed password.
 Can anybody tell what is the way to do this?


Password encryption at client side

**This question is about guaranteeing all arguments are of the same type while exhibiting a reject-early behavior with a clean compiler error, not a template-gibberish error**

I&#39;m creating a function (possibly member function, not that it matters... maybe it does?) that needs to accept an unknown number of arguments, but I want all of them to be the same type.  I know I could pass in an array or vector, but I want to be able to accept the list of args directly without extra structure or even extra brackets.  It doesn&#39;t look like variadic functions by themselves are typesafe, and I wasn&#39;t sure how to go about this w/ variadic template functions.  Here&#39;s essentially what I&#39;m aiming for (more than likely not correct code, and totally not for the purpose of getting lists of dragons, lol):


    //typedef for dragon_list_t up here somewhere.

    enum Maiden {
        Eunice
        , Beatrice
        , Una_Brow
        , Helga
        , Aida
    };

    dragon_list_t make_dragon_list(Maiden...) {
        //here be dragons
    }
OR

    template&lt;Maiden... Maidens&gt; dragon_list_t make_dragon_list(Maidens...) {
        //here be dragons
    }

USAGE

    dragon_list_t dragons_to_slay
        = make_dragon_list(Maiden.Eunice, Maiden.Helga, Maiden.Aida)
    ;

Tried a few things similar to the above already, no dice.  Suggestions?  Obvious oversights I may have made?  I know it may not be a huge deal to do this instead:

    dragon_list_t make_dragon_list(std::array&lt;Maiden&gt; maidens) {
        //here be dragons.
    }
    dragon_list_t dragons_to_slay
        = make_dragon_list({Maiden.Eunice, Maiden.Helga, Maiden.Aida})
    ;

but I&#39;d much rather be able to do it the first way if possible.

I want to pass the movie url from my dynamically generated button to MediaPlayer:

    [button addTarget:self action:@selector(buttonPressed:) withObject:[speakers_mp4 objectAtIndex:[indexPath row]] forControlEvents:UIControlEventTouchUpInside];

but `action:@selector() withObject:` does not work?

Is there any other solution?

Thanks for help!

Passing parameters on button action:@selector

In C/C++, the main function receives parameters which are of type `char*`.

    int main(int argc, char* argv[]){
      return 0;
    }

`argv` is an array of `char*`, and points to strings. Where are these string located? Are they on the heap, stack, or somewhere else?

Where are C/C++ main function&#39;s parameters?

By default, any named function that has the [CmdletBinding()] attribute accepts the `-debug` and `-verbose` (and a few others) parameters and has the predefined `$debug` and `$verbose` variables. I&#39;m trying to figure out how to pass them on to other cmdlet&#39;s that get called within the function.

Let&#39;s say I have a cmdlet like this:

    function DoStuff() {
       [CmdletBinding()]

       PROCESS {
          new-item Test -type Directory
       }
    }

If `-debug` or `-verbose` was passed into my function, I want to pass that flag into the `new-item` cmdlet. What&#39;s the right pattern for doing this?



How to properly use the -verbose and -debug parameters in a custom cmdlet

 
Following on from this post https://stackoverflow.com/questions/4747184/perform-client-side-validation-for-custom-attribute/4782235#4782235

I am trying to get my head around how to do this, passing additional parameters to the client-side script

As I understand it so far to implement custom validation with MVC 3 the following is required 

Create a custom validation attribute
------------------------------------
Based on ValidationAttribute and implementing IClientValidatable. I have also see some examples deriving from ModelValidator, which seems to implement the functionality of both ValidationAttribute and IClientValidatable. So this is my first point of confusion as to what the diffirences are or whether ModelValidator was used in MVC 2 but is now deprecated or what ?

An instance of ModelClientValidationRule must be returned from GetClientValidationRules() to specify details such as the error message, ValidationType (which I understand to be the name of the Javascript function that will perform the client-side validation) and any additional custom parameters that the attribute may have, and that need to be passed to the Javascript validation.

I assume that the runtime (not sure which part of it) then use the `ModelClientValidationRule` to generate html attribute in the tag elements as follows:

    data-val=&quot;true&quot;  (to indicate that the element requires validation)
    data-val-[ValidationType]=[ErrorMessage]
    data-val-[ValidationType].[ValidationParameters(n).Key]=[ValidationParameters(n).Value]

Implement the client-side validation logic
------------------------------------------
A Javascript function must be created and added to jQuery.validators with jQuery.validators.addmethod() so that JQuery is aware of it when it need to be executed. Something like:

    jQuery.validator.addMethod(
        &#39;greaterThan&#39;, 
        function (value, element, params) {
            /.../
           return /* true or false   */ ; 
        },
        &#39;&#39;
    ); 

My question here is whether the signature &#39;function (value, element, params)&#39; is standard for methods that will handle validation and I assume it will be called by some jQuery functionality at the appropriate time such as before a form is submitted or when an element looses fuces or on keyUp events. I just don&#39;t undertand how you can controll this i.e. choose which event is appropriete for yout custom validation.

Implement an unobtrusive adapter
--------------------------------
This translates unobtrusive attributes to; something I am not very clear on, but assume it to be a jQuery Rule, but I am not clear on how those work. Something like

    jQuery.validator.unobtrusive.adapters.add(
        &#39;futuredate&#39;, 
        { },
        function (options) {
            options.rules[&#39;greaterThan&#39;] = true;
            options.messages[&#39;greaterThan&#39;] = options.message;
        }
    ); 

My question here is about &#39;function (options)&#39;. Is this the function that will be called before &#39;function (value, element, params)&#39; and is responsible for extracting the unobtrusive tags into a data structure that can be understood by jQuery.Validation. From the code example it seems to me that options is an object that contains both, the attribute values from the tag (such as options.message) and the jQuery relevant properties it must map to (such as options.messages[&#39;ClientSideValidationFunctionName&#39;]. If so how are custom parameters retrieved and mapped.

I hope I have not added any additional confusion.
