  • Java JFileChooser getAbsoluteFile Add File Extension

    - by ikurtz
    i have this issue working but i would like to know if there is a better way of adding the file extension? what i am doing right now is: String filePath = chooser.getSelectedFile().getAbsoluteFile() + ".html"; im adding the extension hard coded. and then saving to it. just wondering if there is a more robust/logical manner this can be implemented? thank you for your time. EDIT: i ask this as i would like my app to be portable across platforms. so adding .html manually i may make this a windows only solution.

  • MVC validation error with strongly typed view

    - by Remnant
    I have a simple form that I would like to validate on form submission. Note I have stripped out the html for ease of viewing <%=Html.TextBox("LastName", "")%> //Lastname entry <%=Html.ValidationMessage("LastName")%> <%=Html.TextBox("FirstName", "")%>//Firstname entry <%=Html.ValidationMessage("FirstName")%> <%=Html.DropDownList("JobRole", Model.JobRoleList)%> //Dropdownlist of job roles <% foreach (var record in Model.Courses) // Checkboxes of different courses for user to select { %> <li><label><input type="checkbox" name="Courses" value="<%=record.CourseName%>" /><%= record.CourseName%></label></li> <% } %> On submission of this form I would like to check that both FirstName and LastName are populated (i.e. non-zero length). In my controller I have: public ActionResult Submit(string FirstName, string LastName) { if (FirstName.Trim().Length == 0) ModelState.AddModelError("FirstName", "You must enter a first name"); if (LastName.Trim().Length == 0) ModelState.AddModelError("LastName", "You must enter a first name"); if (ModelState.IsValid) { //Update database + redirect to action } return View(); //If ModelState not valid, return to View and show error messages } Unfortunately, this code logic produces an error that states that no objects are found for JobRole and Courses. If I remove the dropdownlist and checkboxes then all works fine. The issue appears to be that when I return the View the view is expecting objects for the dropwdownlist and checkboxes (which is sensible as that is what is in my View code) How can I overcome this problem? Things I have considered: In my controller I could create a JobRoleList object and Course object to pass to the View so that it has the objects to render. The issue with this is that it will overwrite any dropdownlist / checkbox selections that the user has already made. In the parameters of my controller method Submit I could aslo capture the JobRoleList object and Course object to pass back to the View. Again, not sure this would capture any items the user has already selected. I have done much googling and reading but I cannot find a good answer. When I look at examples in books or online (e.g. Nerddinner) all the validation examples involve simple forms with TextBox inputs and don't seems to show instances with multiple checkboxes and dropdownlists. Have I missed something obvious here? What would be best practice in this situation? Thanks

  • How do I track the method the user is looking at in VS 2010 IDE as an Addin

    - by Rob
    I have been wandering around the object model for VS 2010 and haven't been able to work out the best method for watching what the user is looking at in the main edit window. I know that each Class/method/property is broken down into its own . What I would ideally like is to hook to an event which says "The user has moved the cursor onto Project.Class.Method" and ideally "and is looking at line 4". Any suggestions?

  • Do you know why introducing jquery ui autocomplete for my dropdown boxes is also changing my listbox

    - by oo
    I am trying to change my comboboxes to use autocomplete so i leverage the code listed here (which worked perfectly for my dropdowns) The issue is that i also on the same page have a listbox with the following code: <%= Html.ListBox("Cars", Model.BodyParts.Select( x => new SelectListItem { Text = x.Name, Value = x.Id, Selected = Model.CarsSelected.Any(y => y.Id == x.Id) } ))%> and it appears that the jquery ui code is changing this to a autocomplete dropdown as well (as opposed to keeping it as a multi select list box) any idea how to prevent this from happening? i literally am just using the exact code on this page <script type="text/javascript"> (function($) { $.widget("ui.combobox", { _create: function() { var self = this; var select = this.element.hide(); var input = $("<input>") .insertAfter(select) .autocomplete({ source: function(request, response) { var matcher = new RegExp(request.term, "i"); response(select.children("option").map(function() { var text = $(this).text(); if (!request.term || matcher.test(text)) return { id: $(this).val(), label: text.replace(new RegExp("(?![^&;]+;)(?!<[^<>]*)(" + request.term.replace(/([\^\$\(\)\[\]\{\}\*\.\+\?\|\\])/gi, "\\$1") + ")(?![^<>]*>)(?![^&;]+;)", "gi"), "<strong>$1</strong>"), value: text }; })); }, delay: 0, select: function(e, ui) { if (!ui.item) { // remove invalid value, as it didn't match anything $(this).val(""); return false; } $(this).focus(); select.val(ui.item.id); self._trigger("selected", null, { item: select.find("[value='" + ui.item.id + "']") }); }, minLength: 0 }) .addClass("ui-widget ui-widget-content ui-corner-left"); $("<button>&nbsp;</button>") .insertAfter(input) .button({ icons: { primary: "ui-icon-triangle-1-s" }, text: false }).removeClass("ui-corner-all") .addClass("ui-corner-right ui-button-icon") .position({ my: "left center", at: "right center", of: input, offset: "-1 0" }).css("top", "") .click(function() { // close if already visible if (input.autocomplete("widget").is(":visible")) { input.autocomplete("close"); return; } // pass empty string as value to search for, displaying all results input.autocomplete("search", ""); input.focus(); }); } }); })(jQuery); $(function() { $("select").combobox(); }); </script>

  • Encrypt text using a number

    - by Adam Matan
    Project Euler I have recently begun to solve some of the Project Euler riddles. I found the discussion forum in the site a bit frustrating (most of the discussions are closed and poorly-threaded), So I have decided to publish my Python solutions on launchpad for discussion. The problem is that it seems quite unethical to publish these solutions, as it would let other people gain reputation without doing the programming work, which the site deeply discourages. My Encryption problem I want to encrypt my answers so that only those who have already solved the riddles can see my code. The logical key would be the answer to the riddle, which is always numeric. In order to prevent brute-force attacks on my answers, I want to find an encryption algorithm that takes a significantly long time (few seconds) to run. Do you know any such algorithm? I would fancy a Python package, which I can attach to the code, over an external program that might have portability issues. Thanks, Adam

  • Generic Rails Route Representation?

    - by Flemish Bee Cycle
    Given one or more instances of a model (AR or DM, whatever). Is it possible to generate the route in the requirement form, by which I mean "/foos/:id" Given the route: resource :foo do resource :bar end generate_route_method [@foo,@bar] - "/foos/:id/bars/:id" I'm not talking about #foos_path or #polymorphic_path, rather, literally generating the string containing the wildcard components (i.e ":id"), the same as it would appear as if you did "rake routes".

  • Difference between try-finally and try-catch

    - by Vijay Kotari
    What's the difference between try { fooBar(); } finally { barFoo(); } and try { fooBar(); } catch(Throwable throwable) { barFoo(throwable); // Does something with throwable, logs it, or handles it. } I like the second version better because it gives me access to the Throwable. Is there any logical difference or a preferred convention between the two variations? Also, is there a way to access the exception from the finally clause?

  • Is there anything as good as TOAD for Postgres (Windows)?

    - by misc090912
    Hi guys, I'm just looking for a management tool like TOAD for Postgres. Anyone used a good one? Edit - I work mostly within the data itself and the database already has a mature model/design. I use the edit windows the most (well, in TOAD for Oracle anyway.) As far as I know, Toad only exists naturally for: Oracle, MS SQL, DB2 and MySQL... --JS

  • What is a user category exactly?

    - by Andrew
    I wanted to add a tab to the user edit page ie user/%/edit/foo, and was using the twitter module as a model. After much spelunking and stepping through with a debugger, I realised that I needed to add a hook_user function in my module so that the %user_category part of the menu router path would work. It's now functioning as expected, but I don't really have a solid idea of what I just did, and haven't found a good explanation anywhere. Can anyone explain to me what it's about?

    I've just changed jobs. My previous employer uses Subversion, my new employer uses Perforce. Are there any resources out there that'll help me, as a user change my mental model from a Subversion one to a Perforce one?

  • Mongrel not using latest deployed code, despite multiple restarts

    - by ming yeow
    What could be the potential reasons why mongrel does not use the latest code in the ~/current branch? The code changes are in the MODELs. The code changes in the CONTROLLERS TAKE EFFECT. I tried the following: god restart app deploying several times manually stopping mongrel cluster, deleting the pid files, and starting them again Anyone has similar experiences? Where could the server be potentially caching the model files?

  • Python/Tkinter Audio Player

    - by Nicholas Quirk
    Hey everyone reading this, I've recently got into doing GUI development with Python. Tkinter seems like the easiest and most logical choice starting out. I did a little with wxPython but it was more sophisticated than what I needed. Anyway, I'm developing a media player. Right now it's a simple window with a button to load .wav files. The problem is I would like to implement a pause button now. But, when playing a audio file the GUI isn't accessible again (no buttons can be pushed) till the file is done playing. How can I make the GUI dynamic while an audio file is playing? I was thinking this maybe be because I'm using PyAudio, and their implementation doesn't allow this. Anyway, thanks for any advice before hand.

  • Python threads all executing on a single core

    - by Rob Lourens
    I have a Python program that spawns many threads, runs 4 at a time, and each performs an expensive operation. Pseudocode: for object in list: t = Thread(target=process, args=(object)) # if fewer than 4 threads are currently running, t.start(). Otherwise, add t to queue But when the program is run, Activity Monitor in OS X shows that 1 of the 4 logical cores is at 100% and the others are at nearly 0. Obviously I can't force the OS to do anything but I've never had to pay attention to performance in multi-threaded code like this before so I was wondering if I'm just missing or misunderstanding something. Thanks.

  • How to make emacs stay in the current directory

    - by Mad Wombat
    When I start working on a project in emacs, I use M-x cd to get into the project root directory. But every time I use C-x C-f to open a file in one of the subdirectories (like app/model/Store.rb) emacs changes current directory to that of the file. Is there a way to make emacs stay at the root?

  • ASP.NET MVC - View with master page, how to set title?

    What is prefered way of setting html title (in head) for view when using master pages? One way is by using Page.Title in .aspx file, but that requires in master page which can mess with HTML code. So, lets assume no server side controls, only pure html. Any better ideas? UPDATE: I would like to set title in view NOT in the controller or model.

  • Objective-C convention to prevent "local declaration hides instance variable" warning

    - by Nippysaurus
    Is there a common convention for dealing with these scenarios? The following code is what I am using .. -(id) initWithVariableName: (NSString*)variableName withComparisonValue:(NSString*)comparisonValue { self.mustExist = NO; self.reverseCondition = NO; self.regularExpression = NO; self.variableName = variableName; self.comparisonValue = comparisonValue; return self; } But I am getting "Local declaration of 'variableName' hides instance variable" and the same for "comparisonValue". The function signature seems logical to me, but surely there must be a more "acceptable" standard which will still make sense and be accurate but not generate annoying warnings?
