• Fortran intent(inout) v's no intent

  - by Andrew Walker

  Good practice dictates that subroutine arguments in Fortran should each have a specified intent (i.e. intent(in), intent(out) or intent(inout) as described this question): subroutine bar (a, b) real, intent(in) :: a real, intent(inout) :: b b = b + a ... However, not specifying an intent is valid Fortran: subroutine bar (a, b) real, intent(in) :: a real :: b b = b + a ... Are there any real differences beyond compile time checking for an argument specified as intent(inout) and an argument without a specified intent? Is there anything I should worry about if I'm retrofitting intents to older, intent free, code?

• Cleanup for control inside a FlowDocument

  - by Thorarin

  I have a custom control that I use inside a FlowDocument. The control uses a System.Drawing.ImageAnimator to display transparent, animated GIF images. Why is this such a pain in the butt in WPF anyway? :P In my original implementation, this was causing memory leaks when a paragraph containing the control was being deleted from the document, because the ImageAnimator kept a reference to the control for event handling. I've now implemented a WeakEventManager pattern which seems to indeed fix the leak itself, but I would like to stop "OnFrameChanged" events from being fired if a particular animated GIF is not currently in the document, instead of relying on the garbage collector to eventually collect the control objects and my event manager to notice that there no longer are valid listeners to the event. Basically, I would like to take a more active role in this and have the control react to being removed from the FlowDocument. Is there some way to do this? I've been unable to find it. OnVisualParentChanged doesn't get fired, because the direct parent (a Paragraph) is unchanged.

• .NET WebService Custom Attribute

  - by DownChapel

  I would like to add a custom attribute to a asmx web service to determine if the request is valid based on the client IP address. This is a similar idea to the AuthorizeAttribute in ASP.NET MVC. Is there anywhere (e.g. a HTTP module) I can put the code to look at the attribute on the webservice and decide whether to allow the request or not? In my web.config the handler for asmx is the ScriptHandlerFactory from the System.Web.Extensions dll. I have already implemented the functionality with a HTTP module and a config file with a list of allowed URLs, but I would prefer to get rid of the config file and just add an attribute to the webservice class. Thanks

• SQL Server: Must numbers all be specified with latin numeral digits?

  - by Ian Boyd

  Does SQL server expect numbers to be specified with digits from the latin alphabet, e.g.: 0123456789 Is it valid to give SQL Server digits in other alphabets? Rosetta Stone: Latin: 01234567890 Arabic: ?????????? Bengali: ?????????? i know that the client (ADO) will convert 8-bit strings to 16-bit unicode strings using the current culture. But the client is also converting numbers to strings using their current culture, e.g.: SELECT * FROM Inventory WHERE Quantity > ???,?? Which throws SQL Server for fits. i know that the server/database has it's defined code page and locale, but that is for strings. Will SQL Server interpret numbers using the active (or per-login specified) locale, or must all numeric values be specifid with latin numeral digits?

• Alert show when extension of FileUpLoads are not allowed

  - by Vy Clarks

  I have a asp FileUpload control in my aspx page. And the code behind to check file's extension and then insert them into database: private string Write(HttpPostedFile file, string table) { string fileNameMain = Path.GetFileName(file.FileName); // check for the valid file extension string fileExtension = Path.GetExtension(fileNameMain).ToLower(); if (fileExtension.Equals(".pdf") || fileExtension.Equals(".doc")) { ...insert fileupload into database } else { LabelError.Text = "Extension of files are not allowed."; return null; } } With the code above, it checks the extension and then show the message "Extension of files are not allowed." in a LabelError if the fileupload is not allowed. Now, I'm required to do the "check-extension" in the other way: at the moment the client click and choose FileUpload, an alert show "Extension of files are not allowed.". I need a way to make an alert show at the momment the FileUpload choosed in browser. Help!!!!

• What is the String 'volumeName' argument of MediaStore.Audio.Playlists.Members.getContentUri referri

  - by Brett

  I am wanting to query the members of a given playlist. I have the correct playlist id, and want to use a managedQuery() to look at the playlist members in question. What I have is this: private String [] columns = { MediaStore.Audio.Playlists.Members.PLAYLIST_ID, MediaStore.Audio.Playlists.Members.TITLE, }; Uri membersUri = MediaStore.Audio.Playlists.Members.getContentUri(volume, playlistId); Cursor tCursor = managedQuery(membersUri, columns, null, null, null); I don't know what the volume argument needs to be. I've tried this: MediaStore.Audio.Playlists.EXTERNAL_CONTENT_URI.toString() for the "volume" argument. That gives me back a valid content URI that looks like: content://media/external/audio/playlists/2/members However, my cursor comes back null. I probably am way off base -- I know what I want to do is very simple.

• Masked Edit Extender Format Issue

  - by Kumar

  I am using an ASP.NET AJAX Masked Edit Extender to format phone numbers <asp:TextBox ID="tbPhoneNumber" runat="server" /> <ajaxToolkit:MaskedEditExtender TargetControlID="tbPhoneNumber" Mask="(999)999-9999" MaskType="Number" InputDirection="LeftToRight" ClearMaskOnLostFocus="false" ClearTextOnInvalid="false" runat="server" AutoComplete="false" /> On the page load event I am trying to populate the phone textbox as follows: protected void Page_Load(object sender, EventArgs e) { tbPhoneNumber.Text = "(394)456-310"; } So there is one number which is missing at the end to make it a valid phone number. When the page loads I expected the value in the textbox to be (394)456-310_ But it displays (_39)445-6310 Why is this happening?

Thanks.

• recaptcha asp.net always returns invalid

  - by Curtis White

  The reCaptcha example for ASP.NET does not seem to work. I followed the instructions but it always returns false, "The verification words are incorrect.". The entries are good. I'm using localhost as the site but am not getting any public/private key errors which I did get when adding a bad key (as a test). I've seen this error reported a lot but no good answers. Some suggest to call the validate on the control before checking to see if it is valid but this did not work for me.

• How to create Encryption Key for Encryption Algorithms?

  - by Akash Kava

  I want to use encryption algorithm available in .Net Security namespace, however I am trying to understand how to generate the key, for example AES algorithm needs 256 bits, that 16 bytes key, and some initialization vector, which is also few bytes. Can I use any combination of values in my Key and IV? e.g. all zeros in Key and IV are valid or not? I know the detail of algorithm which does lots of xors, so zero wont serve any good, but are there any restrictions by these algorithms? Or Do I have to generate the key using some program and save it permanently somewhere?

• Insert new relationship data in core data

  - by michael

  Hoping someone can shed some light on what I might be doing wrong here. Trying to add an "event" to a list of events, represented by a one to many (inverse) relationship: MyEvents <--- Event This is the code: MyEvents *myEvents = (MyEvents *)[NSEntityDescription insertNewObjectForEntityForName:@"MyEvents" inManagedObjectContext:context]; NSLog(@"MYEVENTS: %@", myEvents); NSLog(@"EVENT: %@", event); [myEvents addEventObject:event]; My context is fine, and both the myEvents and event print perfectly valid information. When I try to add the event that I have (which is passed into this view controller, having been retrieved from core data previously) with this code [myEvents addEventObject:event]; It falls over with *** -[NSComparisonPredicate evaluateWithObject:]: message sent to deallocated instance MyEvents and Event are just the default generated code. MyEvents contains only the relationship to event. Thanks.

• Where and how to validate and map ViewModel?

  - by chobo

  Hi, I am trying to learn Domain Driven Design and recently read that lots of people advocate creating a ViewModels for your views that store all the values you want to display in a given view. My question is how should I do the form validation? should I create separate validation classes for each view, or group them together? I'm also confused on what this would look like in code. This is how I currently think validation and viewmodels fit in to the scheme of things: View (some user input) - Controller - FormValidation(of ViewModel) - (If valid map to ViewModel to Domain Model) - Domain Layer Service - Infrastructure Thanks! P.S. I use Asp.net MVC with C#

• select time (HH:MM:SS.mmm) in javascript

  - by acidzombie24

  I would like the user to select the time in javascript and to avoid selecting the wrong time. How should i do it? Is there some kind of javascript or jquery widget? or should i show the format and allow users to write it in (and i guess check it with regex)? i think these should be valid 1 (1s) 1:5 (1m 5s) 1.5 (1s, 500 milliseconds. not to be confused by the above) 1:2:02 (1h, 2m, 2 seconds) 1:2:2 (1h, 2m, 2 seconds) 1:2:20 (1h, 2m, 20 seconds) I dont want the user to be confused. How can i avoid this?

• Resize a ListView depending on how many items?

  - by Dodi300

  Hello. How can I resize the height of a ListView depending on how many items are in that ListView? I'm trying to get the text of an item which is clicked, however whenever the user clicks on a space which has no item, there's an error. The exact error is: InvalidArgument=Value of '0' is not valid for 'index'. Parameter name: index. I'm using the code: label14.Text = myListView1.SelectedItems[0].Text.ToString(); I figured that removing the space below the items will solve this problem. Thanks!

• ASP.NET Binding integer to CheckBox's Checked field

  - by Sung Meister

  I have a following ListView item template, in which I am trying to bind integer value to Checked property of CheckBox. IsUploaded value contains only 0 and 1... <asp:ListView ID="trustListView" runat="server"> <ItemTemplate> <asp:CheckBox ID="isUploadedCheckBox" runat="server" Checked='<%# Bind("IsUploaded") %>' /> </ItemTemplate> </asp:ListView> But ASP.NET complains that Exception Details: System.InvalidCastException: Sepcified cast is not valid Even though following code using DataBinder.Eval() works, I need to have a 2-way binding, thus need to use Bind(). <asp:CheckBox ID="isUploadedCheckBox2" runat="server" Checked='<%# Convert.ToBoolean( DataBinder.Eval(Container.DataItem, "IsUploaded"))) %>' /> How can I convert 0's and 1's to boolean using Bind()? [ANSWER] I have extended auto-generated type through partial class by adding a new property mentioned in the answer by Justin

• How do I change a Git remote HEAD to point to something besides "master"

  - by jhs

  Short version: How do I set a Git remote's HEAD ref to point to something besides "master"? My project has a policy not to use a "master" branch (all branches are to have meaningful names). Furthermore, the canonical master repository is only accessible via ssh://, with no shell access (like GitHub or Unfuddle). My problem is that the remote repository still has a HEAD reference to refs/heads/master, but I need it to point to a different branch. This is causing two problems: When cloning the repo, there this, warning: remote HEAD refers to nonexistent ref, unable to checkout. That's confusing and inconvenient. The web-based code browser depends on HEAD as a basis for browsing the tree. I need HEAD to point to a valid branch, then.

• Regex in MySql - replace between Tags including Tags

  - by user998163

  I have a text like: [lang_de]Content in German[/lang_de][lang_en]Content in English[/lang_en]. I want to replace all text between [lang_en] and [/lang_en] including the opening and closing language tag. This is my current regex: UPDATE wp_posts SET post_content = '" . addslashes(preg_replace("/[lang_en](.*)[\/lang_en]/", '', $row['post_content'])) . "' WHERE ID = " . $row['ID'] With this regex, I do not get a valid results. It also replaces in html tags and so on. What would be the correct regex?

• AudioQueueOfflineRender returning empty data

  - by hyn

  I'm having problems using AudioQueueOfflineRender to decode AAC data. When I examine the buffer after the call, it is always filled with empty data. I made sure the input buffer is valid and packet descriptions are provided. I searched and found that a few others have had the same problem: http://lists.apple.com/archives/Coreaudio-api/2008/Jul/msg00119.html Also, the inTimestamp argument doesn't make sense to me. Why should the renderer care where in the audio the beginning of the buffer corresponds to? The function throws an error if I pass in NULL, so I pass in the timestamp anyway.

• CherryPy configuration tools.staticdir.root problem

  - by Alan Harris-Reid

  Hi there, How can I make my static-file root directories relative to my application root folder (instead of a hard-coded path)? In accordance with CP instructions (http://www.cherrypy.org/wiki/StaticContent) I have tried the following in my configuration file: tree.cpapp = cherrypy.Application(cpapp.Root()) tools.staticdir.root = cpapp.current_dir but when I run cherrpy.quickstart(rootclass, script_name='/', config=config_file) I get the following error builtins.ValueError: ("Config error in section: 'global', option: 'tree.cpapp', value: 'cherrypy.Application(cpapp.Root())'. Config values must be valid Python.", 'TypeError', ("unrepr could not resolve the name 'cpapp'",)) I know I can do configuration from within the main.py file just before quickstart is called (eg. using os.path.abspath(os.path.dirname(file))), but I prefer using the idea of a separate configuration file if possible. Any help would be appreciated (in case it is relevant, I am using CP 3.2 with Python 3.1) TIA Alan

• JQuery: NOT using document.ready and inserting HTML Tags = is this allowed?

  - by jens

  Hello, is this a valid JQuery usage pattern to : <script type="text/javascript"> $("body").prepend('<input type="hidden" id="error" value="show">'); </script> That is using Jquery to manipulate / insert HTML Tags when the Document has NOT YET been loaded (by not using document.ready for the inserting into the DOM)? (Normally I only use document.ready, but in this case I need to insert some Information into the DOM that then is present, when document.ready is called. This is some kind of "happens-before" relations ship I want to achieve so that I am shure when document.ready is called the inserted Form field is available in the document, as I depend on that information. Thank you very much jens

• Hibernate @OneToOne @NotNull

  - by Marty Pitt

  Is it valid to declare @OneToOne and @NotNull on both sides of a relationship, such as: class ChangeEntry { @OneToOne(cascade=CascadeType.ALL) @NotNull ChangeEntryDetails changeEntryDetails; } class ChangeEntryDetails { @OneToOne(cascase=CascadeType.ALL) @NotNull ChangeEntry changeEntry; } I can't find anything that says this is invalid, but it seems that during persistence at least one side of the relationship must be violated. (Eg., if writing changeEntry first, changeEntryDetails will be null temporarily). When trying this, I see an exception thrown not-null property references a null or transient value. I'd like to avoid relaxing the constraint if possible, because both sides must be present.

• Zend remove anchor text in url redirect

  - by user351785

  I have a form that is using an anchor name as it's action so that when the form is submitted it is it goes straight back to the form (for example 'www.domain.com/page#contact-form). The idea is if there are any errors then it'll go straight to the form (that's near the bottom of the page) so you can see the errors and continue filling in the form. If the form is valid, I want it to redirect to another page (for example www.domain.com/another-page). The problem is that the redirect url still has the anchor text in the url (in the above example it is www.domain.com/another-page#contact-form). I am using $this->_helper->redirector->goToRouteAndExit(array(), 'another-page', true); to goto the another-page route. I have tried setting the url specifically but that doesn't fix it either. How do I redirect to another page and remove that anchor text from the url?

• Simple PHP Regex question

  - by Dave Kiss

  Hi all, I'd like to validate a field in a form to make sure it contains the proper formatting for a URL linking to a Vimeo video. Below is what I have in Javascript, but I need to convert this over to PHP (not my forte) Basically, I need to check the field and if it is incorrectly formatted, I need to store an error message as a variable.. if it is correct, i store the variable empty. // Parse the URL var PreviewID = jQuery("#customfields-tf-1-tf").val().match(/http:\/\/(www.vimeo|vimeo)\.com(\/|\/clip:)(\d+)(.*?)/); if ( !PreviewID ) { jQuery("#cleaner").html('<div id="vvqvideopreview"><?php echo $this->js_escape( __("Unable to parse preview URL. Please make sure it's the <strong>full</strong> URL and a valid one at that.", 'vipers-video-quicktags') ); ?></div>'); return; } The traditional vimeo url looks like this: http://www.vimeo.com/10793773 Thanks!

• How do I use NTLM authentication with Active Directory

  - by Jon Works

  I am trying to implement NTLM authentication on one of our internal sites and everything is working. The one piece of the puzzle I do not have is how to take the information from NTLM and authenticate with Active Directory. There is a good description of NTLM and the encryption used for the passwords, which I used to implement this, but I am not sure of how to verify if the user's password is valid. I am using Coldfusion but a solution to this problem can be in any language (Java, Python, PHP, etc). Edit: I am using Coldfusion on Redhat Enterprise Linux. Unfortunately we cannot use IIS to manage this and instead have to write or use a 3rd party tool for this.
