  • How do I implement a TextBox that displays "Type here"?

    - by mafutrct
    Displaying "Type here to ..." until the user enters text into a TextBox is a well-known usability feature nowadays. How would one implement this feature in C#? My idea is to override OnTextChanged, but the logic to handle the changes of Text from and to "Type here" is a bit tricky... Displaying "Type here" on initialization and removing it on first input is easy, but I want to display the message every time the entered text becomes empty.

  • Determine modifier key state without an InputEvent object in Java

    - by heycam
    I need to determine the current state of the Shift key, but at the time I need the state I don't have an InputEvent object around. I need something like java.awt.Toolkit.getLockingKeyState(int) that works for Shift, not just the locking keys like VK_CAPS_LOCK. Is there a way I can do this without listening to input events and storing the for later when I need to check the state? Thanks!

  • Programming a callback function within a jQuery plugin

    - by ILMV
    I'm writing a jQuery plug-in so I can reuse this code in many places as it is a very well used piece of code, the code itself adds a new line to a table which has been cloned from a hidden row, it continues to perform a load of manipulations on the new row. I'm currently referencing it like this: $(".abc .grid").grid(); But I want to include a callback so each area the plug-in is called from can do something a bit more unique when the row has been added. I've used the jQuery AJAX plug-in before, so have used the success callback function, but cannot understand how the code works in the background. Here's what I want to achieve: $(".abc .grid").grid({ row_added: function() { // do something a bit more specific here } }); Here's my plug-in code (function($){ $.fn.extend({ //pass the options variable to the function grid: function() { return this.each(function() { grid_table=$(this).find('.grid-table > tbody'); grid_hidden_row=$(this).find('.grid-hidden-row'); //console.debug(grid_hidden_row); $(this).find('.grid-add-row').click(function(event) { /* * clone row takes a hidden dummy row, clones it and appends a unique row * identifier to the id. Clone maintains our jQuery binds */ // get the last id last_row=$(grid_table).find('tr:last').attr('id'); if(last_row===undefined) { new_row=1; } else { new_row=parseInt(last_row.replace('row',''),10)+1; } // append element to target, changes it's id and shows it $(grid_table).append($(grid_hidden_row).clone(true).attr('id','row'+new_row).removeClass('grid-hidden-row').show()); // append unique row identifier on id and name attribute of seledct, input and a $('#row'+new_row).find('select, input, a').each(function(id) { $(this).appendAttr('id','_row'+new_row); $(this).replaceAttr('name','_REPLACE_',new_row); }); // disable all the readonly_if_lines options if this is the first row if(new_row==1) { $('.readonly_if_lines :not(:selected)').attr('disabled','disabled'); } }); $(this).find('.grid-remove-row').click(function(event) { /* * Remove row does what it says on the tin, as well as a few other house * keeping bits and pieces */ // remove the parent tr $(this).parents('tr').remove(); // recalculate the order value5 //calcTotal('.net_value ','#gridform','#gridform_total'); // if we've removed the last row remove readonly locks row_count=grid_table.find('tr').size(); console.info(row_count); if(row_count===0) { $('.readonly_if_lines :disabled').removeAttr('disabled'); } }); }); } }); })(jQuery); I've done the usually searching on elgooG... but I seem to be getting a lot of noise with little result, any help would be greatly appreciated. Thanks!

  • Expert R users, what's in your .Rprofile?...

    - by gappy
    This question is maybe a little too cute, but I have always found startup profile files of other people both useful and instructive about the language. Moreover, while I have some customization for bash and vim, I have nothing for R. For example, one thing I always wanted is different colors for input and output text in a window terminal, and maybe even syntax highlighting.

  • Is there any real alternative to GeoServer as dynamic map generator in Java ?

    - by Costi Ciudatu
    I'm looking for the most suitable tool for generating dynamic geographical maps in Java (with styles based on custom business data: colors, labels etc. will be dynamically set). After some searching, only GeoServer (and the underlying GeoTools library) seems to fit. Although I'm really happy with this solution, I'm afraid I might miss something and make some decision based on incomplete input. Any suggestion ? Any viable alternative to compare against ?

  • Is there a "good enough" solution for the halting problem?

    - by EpsilonVector
    It is known that the halting problem cannot have a definite solution, one that a) returns true <== the program does indeed halt, and b) handles any input, but I was wondering if there are good enough solutions to the problem, ones that can maybe handle certain types of program flows perfectly, or is able to identify it when it cannot correctly solve the problem, and so on.... If so, how good are they, and what ideas/limitations do they rely on?

  • How do make my encryption algorithm encrypt more than 128 bits?

    - by Ranhiru
    OK, now I have coded for an implementation of AES-128 :) It is working fine. It takes in 128 bits, encrypts and returns 128 bits So how do i enhance my function so that it can handle more than 128 bits? How do i make the encryption algorithm handle larger strings? Can the same algorithm be used to encrypt files? :) The function definition is public byte[] Cipher(byte[] input) { }

However I'm pretty sure thisis being hijacked and I've found "new" files on my server I didn't put there. My site cleans all user input for SQL injections and XSS but this keeps happening. Has anyone got any ideas on how to solve this?

  • MVC 3 ModelView passing parameters between view & controller

    - by Tobias Vandenbempt
    I've been playing with MVC 3 in a test project and have the following issue. I have Group & Subscriber entities and those are coupled through a SubscriberGroup table. Using the DetailView of Group I open a view of SubscriberGroup containing all subscribers. This list has the option to filter. So far it all works, however when I call the AddToGroup method on the controller it fails. Specifically it goes into the method but doesn't pass the subscriberCheckedModels list. Am I doing something wrong?
