  • InterIMAP, Viewing UNREAD IMAP mail and Downloading Attachments in C#

    - by Erika
    I was wondering if anyone can help me on this cause its driving me mad trying get this working I was working with the trail of mail.dll from http://www.lesnikowski.com/mail/ which is an extremely fantastic tool which unfortunately i cannot afford being a student (even though its around 150eur, its still very expensive to me :/) and this would be a small module in my thesis and my faculty cannot afford to buy these things for students either :/ so anyway I had to go for a free tool (so please dont suggest any non open source ones - trust me i have tried them ALL).. Well, i'm trying to explore InterIMAP, and for several hours have been trying to list unread emails from my gmail account but it just doesn't seem to be working. I can connect just fine but finding the unread emails seems to be no easy task.. I have tried countless approaches but non seem to give me unread emails in my inbox (I have loads of emails in my inbox and i just want the unread ones). Would someone please assist me? I have been trying to get this working for ages now, but documentation is rather lacking and my every attempt has resulted in a fail so far. Please help!! Some code i currently have: ` IMAPConfig config = new IMAPConfig("myhost", "username", "pass", true, true, ""); config.CacheFile = ""; IMAPClient client = null; try { client = new IMAPClient(config, null, 5); } catch (IMAPException e) { Console.WriteLine(e.Message); return; } Console.WriteLine(DateTime.Now.ToString()); IMAPFolder f = client.Folders["INBOX"]; IMAPSearchResult sResult = f.Search(IMAPSearchQuery.QuickSearchNew()); // <--- Gives me no results even though i do have unread messages!

  • iOS 5.0 AVAudioPlayer Error loading audio clip: The operation couldn’t be completed. (OSStatus error -50.)

    - by Jason Catudal
    So I'm trying to test out the audio player on the iPhone, and I went off Troy Brant's iOS book. I have the Core Audio, Core Foundation, AudioToolbox, and AVFoundation frameworks added to my project. The error message I get is in the subject field. I read like 20 pages of Google search results before resorting to asking here! /sigh. Thanks if you can help. Here's my code, pretty much verbatim out of his book: NSString *soundFilePath = [[NSBundle mainBundle] pathForResource:@"Yonah" ofType:@"caf"]; NSLog(@"%@", soundFilePath); NSURL *fileURL = [NSURL URLWithString:soundFilePath]; NSError *error; audioPlayer = [[AVAudioPlayer alloc] initWithContentsOfURL:fileURL error:&error]; if (!error) { audioPlayer.delegate = self; //audioPlayer.numberOfLoops = -1; [audioPlayer play]; } else { NSLog(@"Error loading audio clip: %@", [error localizedDescription]); } EDIT: Holy Shinto. I figured out what it was. I changed NSURL *fileURL = [NSURL URLWithString:soundFilePath]; to NSURL *fileURL = [NSURL fileURLWithPath:soundFilePath]; to the latter and I was getting a weird error, weirder than the one in the subject BUT I googled that and I changed my OS input device from my webcam to my internal microphone and guess what, it worked under the fileURLWithPath method. I'll be. Damned.

  • The best way to package iPhone/iPad static libraries?

    - by Derek Clarkson
    Hi everyone, I have a couple of static Phone/iPad libraries I an working on. The problem I am looking for advise on is the best way to package the libraries. My objective is to make it easy to use the libraries in other projects and include the correct one in a build with minimal problems. To make it more interesting I currently build 4 versions of each library as follows armv6/armv7 release (devices) i386 release (simulator) armv6/armv7 debug (devices) i386 debug (simulator) The difference between the release and debug versions is that the debug versions contain a lot of NSLog(...) code which enables people to see whats going on internally as an aid to debugging. Currently when I build the whole projects I arrange the libraries into two directories like this: release lib-device.a lib-simulator.a debug lib-device.a lib-simulator.a This works ok except that when include in projects, both paths are added to the library search path and switching a target from one to the other is a pain. Or alternatively I end up with two targets. The alternative I am thinking of is to change the directories like this: release device lib.a simulator lib.a debug device lib.a simulator lib.a In playing with XCode is appears that all xcode uses the lbrary references of a project for is to get the name of the library file, which it then looks up in the library paths. Thus by parameterising the library path with the current built type and target device, I can effectively auto switch. What do you guys think? Is there a better way to do this? ciao Derek

  • Perl Curses::UI

    - by user353211
    I am trying to use the library Curses:UI from http://search.cpan.org/dist/Curses-UI/ to build a UI on linux karmic. I can create a simple user interface e.g.: #!usr/usr/bin/perl use strict; use Curses; use Curses::UI; $ui = new Curses::UI(-color_support=1,-clear_on_exit=1,-intellidraw=1); my $window = $ui-add('window', 'Window',intellidraw=1); my $message = $window-add(-text="Hello!",-intellidraw=1); $window-focus(); $ui-mainloop(); Question: I need some way to communicate informatio to the UI i.e. I have a loop which will wait for message to come and change the text in window. Once this message comes a popup will be displayed. Attempt: my $ui = new Curses::UI(-color_support=1,-clear_on_exit=1,-intellidraw=1); my $window = $ui-add('window', 'Window',intellidraw=1); my $message = $window-add(-text="Hello!",-intellidraw=1); pseudocode while(true) #implemented a function to wait { popup($window-text("Hello how are you?")); } $window-focus(); $ui-mainloop(); Problem: The above does not work. I am given a dark screen where my message is displayed. I have read the documentation and when I relocate : $ui-mainloop() above the while loop I am given the user interface but now nothing communicates to the window. Coincise Question: I need some way of displaying the user interface wait for inputs and display messages. Could anyone please help me on this? Thank you!

  • Ruby on Rails: How to sanitize a string for SQL when not using find?

    - by williamjones
    I'm trying to sanitize a string that involves user input without having to resort to manually crafting my own possibly buggy regex if possible, however, if that is the only way I would also appreciate if anyone can point me in the right direction to a regex that is unlikely to be missing anything. There are a number of methods in Rails that can allow you to enter in native SQL commands, how do people escape user input for those? The question I'm asking is a broad one, but in my particular case, I'm working with a column in my Postgres database that Rails does not natively understand as far as I know, the tsvector, which holds plain text search information. Rails is able to write and read from it as if it's a string, however, unlike a string, it doesn't seem to be automatically escaping it when I do things like vector= inside the model. For example, when I do model.name='::', where name is a string, it works fine. When I do model.vector='::' it errors out: ActiveRecord::StatementInvalid: PGError: ERROR: syntax error in tsvector: "::" "vectors" = E'::' WHERE "id" = 1 This seems to be a problem caused by lack of escaping of the semicolons, and I can manually set the vector='\:\:' fine. I also had the bright idea, maybe I can just call something like: ActiveRecord::Base.connection.execute "UPDATE medias SET vectors = ? WHERE id = 1", "::" However, this syntax doesn't work, because the raw SQL commands don't have access to find's method of escaping and inputting strings by using the ? mark. This strikes me as the same problem as calling connection.execute with any type of user input, as it all boils down to sanitizing the strings, but I can't seem to find any way to manually call Rails' SQL string sanitization methods. Can anyone provide any advice?

  • FileDialog DoubleClick Behavior

    - by Shaun Hamman
    While developing a WinForms application, I came across what I believe is a bug in the OpenFileDialog and SaveFileDialog controls. A Google search turned up a single other person who noticed the same issue, but neither a solution nor a workaround was provided. You can view this thread at: http://bytes.com/topic/visual-basic-net/answers/389470-open-file-dialog-picturebox-click-event. I have a custom control on my form that handles the MouseDown event. If I doubleclick a file in a FileDialog control while the mouse is over this control (with the dialog between them, obviously), the MouseDown event gets triggered. I don't think this is an issue with my control, because the person I mentioned before noticed this happening with a PictureBox control. It would seem that even though the mouse button was pressed down (for the second click to open the file) while on the dialog box, the event passed through to the form and my control when the dialog closed. I have tried disabling my control while the dialog box is active, but that didn't stop it from capturing the event. I assume this is because the event is passed down after the dialog closes, so my control would be re-enabled. Does anyone know of a way to prevent that click from reaching the form and, in turn, my control? Also, can anyone confirm if this really is a bug in the FileDialog controls, or if I just have some setting configured incorrectly?

  • Possible to change the alpha value of certain pixels on iPhone?

    - by emi1faber
    Is it possible to change just a portion of a Sprite's alpha in response to user interaction? A good example of what I mean is iFog or iSteam, where the user can wipe "steam" off the iPhone's screen. Swapping images out wouldn't be feasible due to the sheer number of possibilities where the user could touch and move... For example, say you have a simple app that has a brick wall in the background that has graffiti on it, so there'd be two sprites, one of the brick wall, then one of the graffiti that has a higher z value than the brick wall. Then, based upon where the user touches (assuming their touch controls a sandblaster), some of the graffiti should be removed, but not all of it, which could be accomplished by changing the alpha value on a portion of the graffiti sprite. Is there any way to do this in cocos2d-iphone? Or, do I need to drop down into openGL, and if so, where would be a good place to start my search on how to accomplish this? Ideally, I'd like to accomplish this on a cocos2d-iphone Sprite, but if it's not possible, where's the best place to start looking? Thanks in advance, Ben

  • Seperating Javascript and Html, when dynamically adding html via javascript

    - by optician
    I am currently building a very dynamic table for a list application, which will basically perform basic CRUD functions via AJAX. What I would like to do is separate the visual design and javascript to the point where I can change the design side without touching the JS side. This would only work where the design stays roughly the same(i would like to use it for rapid protyping) Here is an example. <table> <tr><td>record-123</td><td>I am line 123</td><td>delete row</td></tr> <tr><td>record-124</td><td>I am line 124</td><td>delete row</td></tr> <tr><td>record-125</td><td>I am line 125</td><td>delete row</td></tr> <tr><td>add new record</td></tr> </table> Now, when I add a new record, I would like to insert a new row of html, but I would rather not put this html into the javascript file. What I am considering is creating a row like this on the page, near the table. <tr style='visble:none;' id='template-row'><td>record-id</td><td>content-area</td><td>delete row</td></tr> And when I come to add the new row, I search the page for the tags with the id=template-row , and then grab it, do a string replace on it, and then put it in the right place in the page. As long as the design doesn't shift radically, and I keep the placeholder strings the same, it means designs can be quickly modified without touching the js. Can any give any advice on a methodology like this?

  • How do I get my custom WPF textbox to fill correctly?

    - by Dan Ryan
    I am trying to create a custom WPF textbox control that extends the standard textbox control but the extended textbox behaves differently when placed in control containers. Within my Window I have a stackpanel with a standard textbox and my extended textbox: <StackPanel Margin="10"> <TextBox Height="21" /> <l:SearchTextBox Search="SearchTextBox_Search" Height="21" Margin="0, 10, 0, 0" SearchMode="Delayed" HorizontalAlignment="Left" /> </StackPanel> The standard textbox stretches the length of the StackPanel whereas the custom textbox does not. How can I get the controls to behave the same? The styling for the custom textbox is shown below: <Style x:Key="{x:Type UIControls:SearchTextBox}" BasedOn="{StaticResource {x:Type TextBox}}" TargetType="{x:Type UIControls:SearchTextBox}"> <Setter Property="Template"> <Setter.Value> <ControlTemplate TargetType="{x:Type UIControls:SearchTextBox}"> <TextBox /> </ControlTemplate> </Setter.Value> </Setter> </Style>

  • How can I test blades in MVC Turbine with Rhino Mocks?

    - by Brandon Linton
    I'm trying to set up blade unit tests in an MVC Turbine-derived site. The problem is that I can't seem to mock the IServiceLocator interface without hitting the following exception: System.BadImageFormatException: An attempt was made to load a program with an incorrect format. (Exception from HRESULT: 0x8007000B) at System.Reflection.Emit.TypeBuilder._TermCreateClass(Int32 handle, Module module) at System.Reflection.Emit.TypeBuilder.CreateTypeNoLock() at System.Reflection.Emit.TypeBuilder.CreateType() at Castle.DynamicProxy.Generators.Emitters.AbstractTypeEmitter.BuildType() at Castle.DynamicProxy.Generators.Emitters.AbstractTypeEmitter.BuildType() at Castle.DynamicProxy.Generators.InterfaceProxyWithTargetGenerator.GenerateCode(Type proxyTargetType, Type[] interfaces, ProxyGenerationOptions options) at Castle.DynamicProxy.DefaultProxyBuilder.CreateInterfaceProxyTypeWithoutTarget(Type interfaceToProxy, Type[] additionalInterfacesToProxy, ProxyGenerationOptions options) at Castle.DynamicProxy.ProxyGenerator.CreateInterfaceProxyTypeWithoutTarget(Type interfaceToProxy, Type[] additionalInterfacesToProxy, ProxyGenerationOptions options) at Castle.DynamicProxy.ProxyGenerator.CreateInterfaceProxyWithoutTarget(Type interfaceToProxy, Type[] additionalInterfacesToProxy, ProxyGenerationOptions options, IInterceptor[] interceptors) at Rhino.Mocks.MockRepository.MockInterface(CreateMockState mockStateFactory, Type type, Type[] extras) at Rhino.Mocks.MockRepository.CreateMockObject(Type type, CreateMockState factory, Type[] extras, Object[] argumentsForConstructor) at Rhino.Mocks.MockRepository.Stub(Type type, Object[] argumentsForConstructor) at Rhino.Mocks.MockRepository.<>c__DisplayClass1`1.<GenerateStub>b__0(MockRepository repo) at Rhino.Mocks.MockRepository.CreateMockInReplay<T>(Func`2 createMock) at Rhino.Mocks.MockRepository.GenerateStub<T>(Object[] argumentsForConstructor) at XXX.BladeTest.SetUp() Everything I search for regarding this error leads me to 32-bit vs. 64-bit DLL compilation issues, but MVC Turbine uses the service locator facade everywhere and we haven't had any other issues, just with using Rhino Mocks to attempt mocking it. It blows up on the second line of this NUnit set up method: IRotorContext _context; IServiceLocator _locator; [SetUp] public void SetUp() { _context = MockRepository.GenerateStub<IRotorContext>(); _locator = MockRepository.GenerateStub<IServiceLocator>(); _context.Expect(x => x.ServiceLocator).Return(_locator); } Just a quick aside; I've tried implementing a fake implementing IServiceLocator, thinking that I could just keep track of calls to the type registration methods. This won't work in our setup, because we extend the service locator's interface in such a way that if the type isn't Unity-based, the registration logic is not invoked.

  • Update CGridView when a dropdown value changes

    - by Gautam Borad
    I have a CGridView with columns from a table "product" => {'product_id','category_id',...} I have another table "category" => {'category_id','category_name'} category_id is the FK in the product table. Now i want a dropdown list of the category table and on selecting a particular value the CGridView of product should be updated to show only the rows with that category_id. I also need the column filtering/sorting for the CGridView to work (using AJAX). I was able to refresh the CGridView when a value is selected from the dropdown, however i am not able to send the category_id with the 'data' for the CGridView: clientScript-registerScript('search', " $('.cat_dropdown').change(function(){ $.fn.yiiGridView.update('order-grid', { data: $(this).serialize(), }); return false; }); "); The data: $(this).serialize() sends only the values that are present in the filtering text fields of the CGridView. How do i append the category_id with it? If the above method is not the right one, please suggest an alternative method.

  • Lucene - querying with long strings

    - by Mikos
    I have an index, with a field "Affiliation", some example values are: "Stanford University School of Medicine, Palo Alto, CA USA", "Institute of Neurobiology, School of Medicine, Stanford University, Palo Alto, CA", "School of Medicine, Harvard University, Boston MA", "Brigham & Women's, Harvard University School of Medicine, Boston, MA" "Harvard University, Cambridge MA" and so on... (the bottom-line being the affiliations are written in multiple ways with no apparent consistency) I query the index on the affiliation field using say "School of Medicine, Stanford University, Palo Alto, CA" (with QueryParser) to find all Stanford related documents, I get a lot of false +ves, presumably because of the presence of School of Medicine etc. etc. (note: I cannot use Phrase query because of variability in the way affiliation is constructed) I have tried the following: Use a SpanNearQuery by splitting the search phrase with a whitespace (here I get no results!) Tried boosting (using ^) by splitting with the comma and boosting the last parts such as "Palo Alto CA" with a much higher boost than the initial phrases. Here I still get lots of false +ves. Any suggestions on how to approach this? If SpanNearQuery the way to go, Any ideas on why I get 0 results?

  • Oracle command hangs when using view for "WHERE x IN..." subquery

    - by Calvin Fisher
    I'm working on a web service that fetches data from an oracle data source in chunks and passes it back to an indexing/search tool in XML format. I'm the C#/.NET guy, and am kind of fuzzy on parts of Oracle. Our Oracle team gave us the following script to run, and it works well: SELECT ROWID, [columns] FROM [table] WHERE ROWID IN ( SELECT ROWID FROM ( SELECT ROWID FROM [table] WHERE ROWID > '[previous_batch_last_rowid]' ORDER BY ROWID ) WHERE ROWNUM <= 10000 ) ORDER BY ROWID 10,000 rows is an arbitrary but reasonable chunk size and ROWID is sufficiently unique for our purposes to use as a UID since each indexing run hits only one table at a time. Bracketed values are filled in programmatically by the web service. Now we're going to start adding views to the indexing, each of which will union a few separate tables. Since ROWID would no longer function as a unique identifier, they added a column to the views (VIEW_UNIQUE_ID) that concatenates the ROWIDs from the component tables to construct a UID for each union. But this script does not work, even though it follows the same form as the previous one: SELECT VIEW_UNIQUE_ID, [columns] FROM [view] WHERE VIEW_UNIQUE_ID IN ( SELECT VIEW_UNIQUE_ID FROM ( SELECT VIEW_UNIQUE_ID FROM [view] WHERE ROWID > '[previous_batch_last_view_unique_id]' ORDER BY VIEW_UNIQUE_ID ) WHERE ROWNUM <= 10000 ) ORDER BY VIEW_UNIQUE_ID It hangs indefinitely with no response from the Oracle server. I've waited 20+ minutes and the SQLTools dialog box indicating a running query remains the same, with no progress or updates. I've tested each subquery independently and each works fine and takes a very short amount of time (<= 1 second), so the view itself is sound. But as soon as the inner two SELECT queries are added with "WHERE VIEW_UNIQUE_ID IN...", it hangs. Why doesn't this query work for views? In what important way are they not interchangeable here?

  • Iphone SQLite Databse with german umlauts results in NULL value

    - by Daniel
    Hi guys, I'm quite new to the Iphone development and after search for an answer for 3 hours now, I hope that you guys can give me a hand. My problem is that I have a SQLite Database with german umlauts. Looking at it with a SQLite browser tool shows me that the data is stored with german umlauts, correctly. But selecting fields with german umlauts in it results in a NULL value. I'm already using "stringWithUTF8String", so I don't get the point where the problem is placed. Here is my code: -(void) readSearchFromDatabase { searchFlag = YES; // Setup the database object sqlite3 *database; // Init the SCode Array searchSCodes = [[NSMutableArray alloc] init]; // Open the database from the users filessytem if(sqlite3_open([databasePath UTF8String], &database) == SQLITE_OK) { NSString *wildcard =@"%"; // Setup the SQL Statement and compile it NSString *sql = [NSString stringWithFormat:@"SELECT * FROM scode WHERE ta LIKE '%@%@%@' OR descriptionde LIKE '%@%@%@' OR descriptionen LIKE '%@%@%@'", wildcard, searchBar.text, wildcard, wildcard, searchBar.text, wildcard, wildcard, searchBar.text, wildcard, wildcard, searchBar.text, wildcard]; //Creating a const char SQL Statement especially for SQLite const char *sqlStatement = [sql UTF8String]; sqlite3_stmt *compiledStatement; if(sqlite3_prepare_v2(database, sqlStatement, -1, &compiledStatement, NULL) == SQLITE_OK) { // Loop through the results and add them to the feeds array while(sqlite3_step(compiledStatement) == SQLITE_ROW) { // Read the data from the result row NSString *aTa = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 0)]; NSString *aReport = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 1)]; NSString *aDescriptionDE = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 2)]; NSString *aDescriptionEN = [NSString stringWithUTF8String:(char *)sqlite3_column_text(compiledStatement, 3)]; //Results a NULL value NSLog(@"Output: %@", aDescriptionDE); // Create a new SCode object with the data from the database SCode *searchSCode = [[SCode alloc] initWithTa:aTa report:aReport descriptionDE:aDescriptionDE descriptionEN:aDescriptionEN]; // Add the SCode object to the SCodes Array [searchSCodes addObject:searchSCode]; [searchSCode release]; } } // Release the compiled statement from memory sqlite3_finalize(compiledStatement); } sqlite3_close(database); }

  • Sql Query - Selecting rows where user can be both friend and user

    - by Gublooo
    Hey Sorry the title is not very clear. This is a follow up to my earlier question where one of the members helped me with a query. I have a following friends Table Friend friend_id - primary key user_id user_id_friend status The way the table is populated is - when I send a friend request to John - my userID appears in user_id and Johns userID appears in user_id_friend. Now another scenario is say Mike sends me a friend request - in this case mike's userID will appear in user_id and my userID will appear in user_id_friend So to find all my friends - I need to run a query to find where my userID appears in both user_id column as well as user_id_friend column What I am trying to do now is - when I search for user say John - I want all users Johns listed on my site to show up along with the status of whether they are my friend or not and if they are not - then show a "Add Friend" button. Based on the previous post - I got this query which does part of the job - My example user_id is 1: SELECT u.user_id, f.status FROM user u LEFT OUTER JOIN friend f ON f.user_id = u.user_id and f.user_id_friend = 1 where u.name like '%' So this only shows users with whom I am friends where they have sent me request ie my userID appears in user_id_friend. Although I am friends with others (where my userID appears in user_id column) - this query will return that as null To get those I need another query like this SELECT u.user_id, f.status FROM user u LEFT OUTER JOIN friend f ON f.user_id_friend = u.user_id and f.user_id = 1 where u.name like '%' So how do I combine these queries to return 1 set of users and what my friendship status with them is. I hope my question is clear Thanks

  • Trouble with Rails has_many relationships

    - by Tchock
    I'm writing an app where a user can both create their own pages for people to post on, and follow posts on pages that users have created. Here is what my model relationships look like at the moment... class User < ActiveRecord::Base has_many :pages has_many :posts has_many :followings has_many :pages, :through => :followings, :source => :user class Page < ActiveRecord::Base has_many :posts belongs_to :user has_many :followings has_many :users, :through => :followings class Following < ActiveRecord::Base belongs_to :user belongs_to :page class Post < ActiveRecord::Base belongs_to :page belongs_to :user The trouble happens when I try to work my way down through the relationships in order to create a homepage of pages (and corresponding posts) a given user is following (similar to the way Twitter's user homepage works when you login - a page that provides you a consolidated view of all the latest posts from the pages you are following)... I get a "method not found" error when I try to call followings.pages. Ideally, I'd like to be able to call User.pages in a way that gets me the pages a user is following, rather than the pages they have created. I'm a programming and Rails newb, so any help would be much appreciated! I tried to search through as much of this site as possible before posting this question (along with numerous Google searches), but nothing seemed as specific as my problem...

  • Circular file references not allowed

    - by Program.X
    Hi, I am having a problem in building my solution in VS2008. Normally, it compiles fine in the environment. Sometimes, it fails with: /xxx_WEB/secure/CMSManagedTargetPage.aspx(1): error ASPPARSE: Circular file references are not allowed. I rebuild and it works fine. Now, however, I am in the middle of setting up a CruiseControl.NET system and am testing my checked out code with MSBuild before I integrate the build into CC. Now, everytime I MSBuild, I get: "Q:\cc\xxx\checked out from svn\xxx.sln" (default target) (1) -> (xxx_WEB target) -> /xxx_WEB/secure/CMSManagedTargetPage.aspx(1): error ASPPARSE: Circular file references are not allowed. Problem is, I can't see where this reference is. I have searched for the reference across the entire solution and canf ind no references to the page itself (CMSManagedTargetPage) anywhere other than in the page or its codebehind, or within a string, eg: C:\dev2008\xxx\IWW.xxx.ASPNET\AspxHttpHandler.cs(82): inputFile = context.Server.MapPath("~/secure/CMSManagedTargetPage.aspx"); C:\dev2008\xxx\IWW.xxx.ASPNET\AspxHttpHandler.cs(83): virtualPath = "~/secure/CMSManagedTargetPage.aspx"; My assembly references are also fine (as far as I know). My Web Application is at the "top" of the dependencies, and nothing references it and therefore the faulting page so cannot cause a circular reference. Of course, the page itself may reference something such as a UserControl within the same assembly/web site, but as mentioned earlier, a search on CMSManagedTargetPage yielded no results so this is not happening. Changing the batch attribute in web.config had no effect on MSBuild. I find it very odd that it "sometimes" fails in VS and always fails in MSBuild. Am I missing some subtlety?

  • split video (avi/h264) on keyframe

    - by m.sr
    Hallo. I have a big video file. ffmpeg, tcprobe and other tool say, it is an h264-stream in an AVI-container. Now i'd like to cut out small chunks form the video. Problem: The index of the video seam corrupted/destroyed. I kind of fixed this via mplayer -forceidx -saveidx <IndexFile> <BigVideoFile>. The Problem here is, that I'm now stuck with mplayer/mencoder which can use this index file via -loadidx <IndexFile>. I have tried correcting the index like described in man aviindex (mplayer -frames 0 -saveidx mpidx broken.avi ; aviindex -i mpidx -o tcindex ; avimerge -x tcindex -i broken.avi -o fixed.avi), but this didn't fix my video - meaning that most tools i've tested couldn't search in the video file. Problem: I sut out parts of the video via following command: mencoder -loadidx in.idx -ss 8578 -endpos 20 -oac faac -ovc x264 -sws 9 -lavfopts format=mp4 -x264encopts <LotsOfOpts> -of lavf -vf scale=800:-10,harddup in.avi -o out.mp4. Now here the problem is, that some videos are corrupted at the beginning. I think this is because the fact, that i do not necessarily cut at keyframe. Questions: What is the best way to fix the index of an avi "inline" so that every tool can again work as expected with it? How can i split at the keyframes? Is there an mencoder-option for this? Are Keyframes coming in a frequency? How to find out this frequency? (So with a bit of math it should be possible to calculate the next keyframe and cut there) Is ther perhaps some completely other way to split this movie? Doing it by hand is no option, i've to cut out 1000+ chunks ... Thanks a lot!

  • How to remove old indexed URLs from Google?

    - by Gok Demir
    I used Cs-cart for a site. Default installation SEO is not suitable for Turkish accented characters such as "ö" which maps to automatically "ae". Then I modified the php code and now it substitutes "ö" with "o" and "s"-"s" etc. Also I changed a category name to a better one. My problem is, google indexed both previous versions and new versions. Previous wrong urls gives 404 error. I used sitemap addon and send it to google and sitemap does not include wrong urls. However these old urls are still indexed on google. What can I do to remove them. For example http://www.google.com.tr/search?q=%C3%A7ak%C4%B1l+ta%C5%9Flar%C4%B1ndan+babil+site:eeski.com&hl=tr&client=firefox-a&hs=Z31&rls=com.ubuntu:en-US:official&filter=0 gives two top results old wrong url leads to 404: http://www.eeski.com/kitap-dergi/bilim-ve-teknik/cakl-talarndan-babil-kulesine-rakamlarn-evrensel-tarihi-ii.html right current url: http://www.eeski.com/kitap/bilim-ve-teknik/cakil-taslarindan-babil-kulesine-rakamlarin-evrensel-tarihi-ii.html What could I make google only index current urls stated on sitemap?

  • How to best handle exception to repeating calendar events

    - by blcArmadillo
    I'm working on a project that will require me to implement a calendar. I'm trying to come up with a system that is very flexible: can handle repeating events, exceptions to repeats, etc. I've looked at the schema for applications like iCal, Lotus Notes, and Mozilla to get an idea of how to go about implementing such a system. Currently I'm having trouble deciding what is the best way to handle exceptions to repeating events. I've used databases quite a bit but don't have a ton of experience with really optimizing everything so I'm not sure which method of the two I'm considering would be optimal in terms of overall performance and ability to query/search: Breaking the repeating event. So taking the changing the ending date on the current row for the repeating event, inserting a new row with the exception, and adding another row continuing the old sequence. Simply adding an exception. So adding a new row with some field that indicates it as an override. So here is why I can't decide. Method one will result in a lot more rows since each edit requires 2 extra rows as apposed to only one row by the second method. On the other hand I think the query to find an event would be much simper, and thus possibly faster(?) using the first method. The second method seems like it will require more calculating on the application server since once you get the data you'll have to remove the intersection of the two rows. I know databases are often the bottleneck for websites and while I'm sure a lot of you are thinking either is fine because your project will probably never get large enough for the difference in efficiency to really matter, I'd still like to implement the best solution. So what method would you guys pick, or would you do something completely different? Also, as a side note I'll be using MySQL and PHP. If there is another technology that you think would be better suited for this, especially in the database area, please mention it. Thanks for the advice.

  • Design patter to keep track UITableView rows correspondance to underlying data in constant time.

    - by DenNukem
    When my model changes I want to animate changes in UITableView by inserting/deleting rows. For that I need to know the ordinal of the given row (so I can construct NSIndexPath), which I find hard to do in better-than-linear time. For example, consider that I have a list of addressbook entries which are manualy sorted by the user, i.e. there is no ordering "key" that represents the sort order. There is also a corresponding UITableView that shows one row per addressbook entry. When UITableView queries the datasource I query the NSMUtableArray populated with my entries and return required data in constant time for each row. However, if there is a change in underlying model I am getting a notification "Joe Smith, id#123 has been removed". Now I have a dilemma. A naive approach would be to scan the array, determine the index at which Joe Smith is and then ask UITableView to remove that precise row from the view, also removing it form the array. However, the scan will take linear time to finish. Now I could have an NSDictionary which allows me to find Joe Smith in constant time, but that doesn't do me a lot of good because I still need to find his ordinal index within the array in order to instruct UITableView to remove that row, which is again a linear search. I could further decide to store each object's ordinal inside the object itself to make it constant, but it will become outdated after first such update as all subsequent index values will have changed due to removal of an object. So what is the correct design pattern to accurately reflect model changes in the UITableView in costant (or at least logarithmic) time?
