  • Secure Desktop Mode effect for java application

    - by Aiden Strydom
    Does anyone now how to achieve a "Secure-Desktop Mode" (effect) such as one gets from the Windows Vista/7 UAC consent-blocks? I assume it is some function which will remove pixels here-and-there (and possibly graying them) and then finally drawing that to screen... I would like to apply it to my application to keep the user from doing anything until the another user connects to the system (but that is besides the point) I would really appreciate the advise. Kind regards A EDIT: i was really only looking for this graphicsFX.setColor(new Color(0, 0, 0, 0.8f)); graphicsFX.fillRect(0, 0, 800, 600); the defering of input i can do quite well... Thanks for all....

  • cannot print popup displaying pdf file

    - by user369544
    I have a php file with the following code: <?php ?> <form action="" id="f1" name="f1"> <input type="button" name="preview" value="Open PDF" onclick="showPDF()" /> </form> <script type="text/javascript" src="jquery-1.4.2.min.js"></script> <script type="text/javascript"> function showPDF(){ var newwin=window.open("pdf.pdf","Window1","menubar=no,width=430,height=360,toolbar=no"); newwin.print(); } </script> It opens up a popup window with pdf file inside it BUT fails to open the print dialog box. But the same code without the pdf filename i.e var newwin=window.open("","Window1","menubar=no,width=430,height=360,toolbar=no"); opens up the popup window and show the print dialog box. Can anybody provide me a solution to this

  • Regular Expression for accurate word-count using JavaScript

    - by Haidon
    I'm trying to put together a regular expression for a JavaScript command that accurately counts the number of words in a textarea. One solution I had found is as follows: document.querySelector("#wordcount").innerHTML = document.querySelector("#editor").value.split(/\b\w+\b/).length -1; But this doesn't count any non-Latin characters (eg: Cyrillic, Hangul, etc); it skips over them completely. Another one I put together: document.querySelector("#wordcount").innerHTML = document.querySelector("#editor").value.split(/\s+/g).length -1; But this doesn't count accurately unless the document ends in a space character. If a space character is appended to the value being counted it counts 1 word even with an empty document. Furthermore, if the document begins with a space character an extraneous word is counted. Is there a regular expression I can put into this command that counts the words accurately, regardless of input method?

  • How can I get gradients working in IE9?

    - by gladoscc
    CSS: .silver { color: #636363; border: solid 1px #9C9C9C; background: #D6D6D6; /*important part*/ background: -webkit-gradient(linear, left top, left bottom, from(#E8E8E8), to(#BABABA)); background: -moz-linear-gradient(top, #E8E8E8, #BABABA); -ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr='#e8e8e8', endColorstr='#bababa')"; filter: progid:DXImageTransform.Microsoft.gradient(startColorstr='#e8e8e8', endColorstr='#bababa'); padding: 2px 5px 2px 5px; -webkit-border-radius: 5px; -moz-border-radius: 5px; border-radius: 5px; margin-right: 5px; font-size: 95%; } This works when I apply to class to a input / submit button, but the gradients do not display when I apply the class to a span or div. How can I get gradients working in IE9?

  • Javascript & jquery : Unable to increment within a form

    - by Daniyal
    I got a simple increment function like this: $(function(){ $("#inc").click(function(){ var value = parseInt($(":text[name='ice_id']").val()) + 1; $(":text[name='ice_id']").val(value); }); $("#dec").click(function(){ var value = parseInt($(":text[name='ice_id']").val()) - 1; $(":text[name='ice_id']").val(value); }); }); the ice_id text field is embedded within a form <form id="masterSubmit" name="masterSubmit" action="" method="post"> <td><input id="ice_id" type="text" name="ice_id" size="16" maxlength="15"></td> </form> When I try now to increment , it successfully increments a number, but shows the following weird behavior: It 'refreshes' the site, so that the content of the text field is gone. This behavior disappears, if I comment out the form tags ...unfortunately the form tags are required for an AJAX-submit. Are there any ways to avoid this problem? Thanks in advance for any hints and best regards Daniyal

  • Mixing expressions and expression language (<%= %> inside of c:if)

    - by Jack
    I need to access some constants in my jsp, and sadly the EL does not offer any functionality for it. There are some options like the unstandard tag library, but I'd like to keep it a bit more standard. I tried: <%@ page import = "com.jackdane.Constants"%> <c:if test="${object.display == '<%=com.jackdane.Constants.YES %>}'"> //some display logic </c:if> But that doesn't appear to do the trick. It's been a while since I've used an expression so I might have made an error. Any input is appreciated. Edit: To clarify, the constants class is not in my control. It's inside a jar file that I recieved. It contains no getters/setters. Just private static final Strings.

  • How to capture the value change of numericUpDown ctrl real-time in .NET?

    - by Carlos_Liu
    I have implement the ValueChanged event, but I found it will be triggered only after change the focus from numericUpDown to other control or by clicking the up/down arrow. Inputting the value in the control will not trigger ValueChanged event. What I did now is adding an KeyDown event and judge if the input value is numeric (can not include SHIFT/CTRL/ALT key); but there is another case need to be involved: the user can paste value into the numericUpDown ctrl What I need is : When I was typing numeric value (only numeric) in the numericUpDown ctrl, it will known the content has been changed; When pasted a numeric value into the ctrl, it also kowns the content changed

  • Cluster of computers for rent?

    - by R S
    I am doing a project in the university which requires running of multiple instances (1000s) of a program I've written (in C++), which runs for quite a while (say 2 hours). The program is very self contained - it does not require input files, and the only dependency I think is boost. I'm currently using the university-owned cluster of computer. However, it's quite old and the jobs dispatching and monitors services are pretty bad. So I was wondering whether I can run my jobs elsewhere, for some money. For example, I looked a bit into Google App Engine, but as it seems every job must end after 30 seconds it is not suitable for me. Maybe Amazon EC2? Do you know of such options?

  • Sharing state/changes across ViewModels

    - by joshperry
    I have an App which has a Tasks tab and a Projects tab. I decided to make a separate ViewModel for each of the tabs, TasksViewModel and ProjectsViewModel. The Tasks tab has a new task area with an associated project pulldown and the Projects tab (obviously) has a list of projects. What I'd like is for the pulldown on the Tasks tab to share the same collection as the Projects tab list so that any time I add or remove a project on the Projects tab the list on the Tasks tab is up to date automatically. This worked well with a single ViewModel but it was beginning to become quite unruly. Should I not have split into two ViewModels? Is there a common method of sharing data like this? Perhaps pass the same ObservableCollection<Project> into each of the ViewModels? Perhaps some type of notification back to the TasksViewModel along the lines of ICollectionChanged. Appreciate any insight/input!

  • Does Len function only evaluate numerical results?

    - by Mel
    Why does the following code not output "Error" if the form is submitted with a blank field? Does Len only evaluate numerical values? <cfif NOT Len(Trim("Form.myField"))> <cfoutput>Error</cfoutput> </cfif> The following also does not evaluate as expected: <cfif Len(Trim("Form.myField")) IS 0> <cfoutput>Error</cfoutput> </cfif> HTML: <input type="text" name="myField" value="">

  • Which would be better? Storing/access data in a local text file, or in a database?

    - by TerranRich
    Basically, I'm still working on a puzzle-related website (micro-site really), and I'm making a tool that lets you input a word pattern (e.g. "r??n") and get all the matching words (in this case: rain, rein, ruin, etc.). Should I store the words in local text files (such as words5.txt, which would have a return-delimited list of 5-letter words), or in a database (such as the table Words5, which would again store 5-letter words)? I'm looking at the problem in terms of data retrieval speeds and CPU server load. I could definitely try it both ways and record the times taken for several runs with both methods, but I'd rather hear it from people who might have had experience with this. Which method is generally better overall?

  • PHP code in drupal pages treating > as ?>

    - by AmaDaden
    While working on an existing Drupal site I've noticed a strange glitch that causes any PHP operator with in it to act like a ? tag. This is happening in in Drupal pages that I create that have a 'Input Format' of 'PHP code'. For example this line of code foreach($array as $key = $value){ results in a very broken page that prints out $value){ Does any one know what could be causing this? My Dev environment is XAMPP. Drupal version is 6.15. PHP version is 5.2.9.

  • GoTo statements and alternatives in VB.NET

    - by qais
    I've posted a code snippet on another forum asking for help and people pointed out to me that using GoTo statements is very bad programming practice. I'm wondering: why is it bad? What alternatives to GoTo are there to use in VB.NET that would be considered generally more of a better practice? Consider this snippet below where the user has to input their date of birth. If the month/date/year are invalid or unrealistic(using if statements checking the integer inputs size, if there's a better way to do this, I'd appreciate if you could tell me that also :D) How would I be able to loop back to ask the user again? retryday: Console.WriteLine("Please enter the day you were born : ") day = Console.ReadLine If day > 31 Or day < 1 Then Console.WriteLine("Please enter a valid day") GoTo retryday End If

    - by cmptrer
    Hey all, I'm new to using WPF. I have the following program I want to create: -Application opens up with one button -User clicks button and it takes them to a new page with various input. I'm confused about how I need to do this. I tried opening a new window, but I don't want a window to open up, I want it to be all one Window. I tried creating a new page and navigating to it using NavigationService but couldn't get it to work. Basically I want to create a workflow where the user enters some stuff, clicks the next button and is taken to a new page to enter some more information. Can anyone point me in the right direction?

  • Finding a Eulerian Tour

    - by user590903
    I am trying to solve a problem on Udacity described as follows: # Find Eulerian Tour # # Write a function that takes in a graph # represented as a list of tuples # and return a list of nodes that # you would follow on an Eulerian Tour # # For example, if the input graph was # [(1, 2), (2, 3), (3, 1)] # A possible Eulerian tour would be [1, 2, 3, 1] I came up with the following solution, which, while not as elegant as some of the recursive algorithms, does seem to work within my test case. def find_eulerian_tour(graph): tour = [] start_vertex = graph[0][0] tour.append(start_vertex) while len(graph) > 0: current_vertex = tour[len(tour) - 1] for edge in graph: if current_vertex in edge: if edge[0] == current_vertex: current_vertex = edge[1] else: current_vertex = edge[0] graph.remove(edge) tour.append(current_vertex) break return tour graph = [(1, 2), (2, 3), (3, 1)] print find_eulerian_tour(graph) >> [1, 2, 3, 1] However, when submitting this, I get rejected by the grader. I am doing something wrong? I can't see any errors.

  • When will YOU adopt C++0x?

    - by HighCommander4
    I'm particularly looking for input from managers of ongoing C++ projects: Have you already adopted C++0x? If so, what has your experience been like? If you haven't adopted C++0x yet, are you planning to? If so, what is your timeline (in rough terms)? Are there any obstacles that are holding you back from adopting C++0x? Perhaps you are waiting for your favourite compiler or IDE to catch up? For managers of open source projects: are you afraid that adopting C++0x will mean less developers who are willing/able to contribute because they don't know the new features? Or, on the other hand, do you think most developers have been eagerly awaiting C++0x, and and will jump at the opportunity to use it? Do you think C++0x is stable enough to be adopted by a large project?

  • How do I pass custom action data from a Visual Studio Setup MSI to an output project via a Merge mod

    - by Lex
    I have a fully working Setup project within Visual Studio 2008 that takes inputs from a UI and passes them via a Custom Action to the output - this works perfectly. Now I have to change this so that the UI is still in a setup project but that the output is within a merge module. The current Custom Action Data looks much like the following with EditHostUrl coming from a UI dialog editbox. /HostUrl="[EditHostUrl]" I now need to pass this value to the merge module and then from there use it as an input for the custom action data to the project output but there does not seem to be any documentation on how to achieve this. To be clear Wix/InstallShield etc... are not currently options. I would also rather not embed the UI within the merge module (for reasons of separation and also it's not supported out of the box with visual studio).

  • Minimizing Java Thread Context Switching Overhead

    - by binil
    I have a Java application running on Sun 1.6 32-bit VM/Solaris 10 (x86)/Nahelem 8-core(2 threads per core). A specific usecase in the application is to respond to some external message. In my performance test environment, when I prepare and send the response in the same thread that receives the external input, I get about 50 us advantage than when I hand off the message to a separate thread to send the response. I use a ThreadPoolExecutor with a SynchronousQueue to do the handoff. In your experience what is the acceptable delay between scheduling a task to a thread pool and it getting picked up for execution? What ideas had worked for you in the past to try improve this?

  • MVC - Sanitizing data, where?

    - by dierre
    I'm using CakePHP but it's a question about the MVC pattern. I have in my form the input-text for the tags (separated by commas). To add the tags I've created a Tag model method that basically check if the tag exists and then add the new tag or just a new unit in the tag counter (the Tag model has these fields: id, name, slug, count). In the controller I explode the tags field and pass one tag at a time. The question is: where do I sanitize data? In the controller or in the model method? I think it should be in the controller because that's where I explode but in term of reusability I think I should sanitize data in the model. What do you think?

  • getElementsByTagName() equivalent for textNodes

    - by levik
    Is there any way to get the collection of all textNode objects within a document? getElementsByTagName() works great for Elements, but textNodes are not Elements. Update: I realize this can be accomplished by walking the DOM - as many below suggest. I know how to write a DOM-walker function that looks at every node in the document. I was hoping there was some browser-native way to do it. After all it's a little strange that I can get all the <input>s with a single built-in call, but not all textNodes.

  • form submits in FireFox when any button on page is clicked

    - by RememberME
    First time using Asp.net-mvc and originally followed the NerdDinner tutorial. My form submit button looks like this: <p> <input type="submit" value="Save" /> </p> I've now added another button to the page with jQuery code attached. It works in IE, but when I test in FireFox the form submits. I tried adding another button, this time with no attached jQuery code and the same thing happens. When the button is clicked, the form submits. <button id="random-button">Do Nothing</button> ??

  • How to change the range of a chart in Excel using VBA?

    - by Pieter
    Hi guys, I'm using an Excel sheet to keep track of a particular time series (my daily weight, if you must know). I created a macro that inserts a row, automatically adds today's date and calculates a moving average based on my input. There is also a chart to visualize my progress. I have tried recording a macro that updates the time series in the graph, but to no success. How can I create a macro or VBA script that, when executed, updates the range of the graph from A(x):Cy to A(x-1):Cy to include today's measurement? Thanks!
