  • How to stop a Timer-X timer (jQuery)

    - by Damien K.
    I'm using Timer-X's timerDelayCall function in order to have a repeating rotator on my page, which starts automatically as the page loads: jQuery.timerDelayCall({ interval: 2000, repeat: true, callback: function(timer) { ... (my rotator logic here) } } }); The problem is that I'm trying to make a function that includes stopping that timer: function signUp() { ... (timer stop code here) } The documentation stats that timer.stop() does that, but however I format it, I get errors about it not being declared. I have tried every variation I can think of, such as: timer.stop(); jQuery.timer.stop(); $(document).timer.stop(); jQuery.timerDelayCall({ callback: function(timer) { timer.stop() } }); I'm sure I'm missing something simple - I come from a PHP background yet I'm new to javascript - but can't see what it is exactly. Help is much appreciated!

  • Syncronizing indices of function pointer table to table contents

    - by Thomas Matthews
    In the embedded system I'm working on, we are using a table of function pointers to support proprietary Dynamic Libraries. We have a header file that uses named constants (#define) for the function pointer indices. These values are used in calculating the location in the table of the function's address. Example: *(export_table.c)* // Assume each function in the table has an associated declaration typedef void (*Function_Ptr)(void); Function_Ptr Export_Function_Table[] = { 0, Print, Read, Write, Process, }; Here is the header file: *export_table.h* #define ID_PRINT_FUNCTION 1 #define ID_READ_FUNCTION 2 #define ID_WRITE_FUNCTION 3 #define ID_PROCESS_FUNCTION 4 I'm looking for a scheme to define the named constants in terms of their location in the array so that when the order of the functions changes, the constants will also change. (Also, I would like the compiler or preprocessor to calculate the indices to avoid human mistakes like typeo's.)

  • Erroneous Matches with Regular Expression

    - by Ballsacian1
    $regexp = '/(?:<input\stype="hidden"\sname="){1}([a-zA-Z0-9]*)(?:"\svalue="1"\s\/>)/'; $response = '<input type="hidden" name="7d37dddd0eb2c85b8d394ef36b35f54f" value="1" />'; preg_match($regexp, $response, $matches); echo $matches[1]; // Outputs: 7d37dddd0eb2c85b8d394ef36b35f54f So I'm using this regular expression to search for an authentication token on a webpage implementing Joomla in order to preform a scripted login. I've got all this working but am wondering what is wrong with my regular expression as it always returns 2 items. Array ( [0] => [1] => 7d37dddd0eb2c85b8d394ef36b35f54f) Also the name of the input I'm checking for changes every page load both in length and name.

  • Castle Windsor Weak Typed Factory

    - by JeffN825
    In a very very limited number of scenarios, I need to go from an unknown Type (at compile time) to an instance of the object registered for that type. For the most part, I use typed factories and I know the type I want to resolve at compile time...so I inject a Func<IMyType> into a constructor ...but in these limited number of scenarios, in order to avoid a direct call to the container (and thus having to reference Windsor from the library, which is an anti-pattern I'd like to avoid), I need to inject a Func<Type,object>...which I want to internally container.Resolve(type) for the Type parameter of the Func. Does anyone have some suggestions on the easiest/most straightforward way of setting this up? I tried the following, but with this setup, I end up bypassing the regular TypedFactoryFacility altogether which is definitely not what I want: Kernel.Register(Component.For(typeof (Func<Type, object>)).LifeStyle.Singleton.UsingFactoryMethod( (kernel, componentModel, creationContext) => kernel.Resolve(/* not sure what to put here... */))); Thanks in advance for any assistance.

  • How can I (is there a way to) convert an HRESULT into a system specific error message?

    - by Billy ONeal
    According to this, there's no way to convert a HRESULT error code into a Win32 error code. Therefore (at least to my understanding), my use of FormatMessage in order to generate error messages (i.e. std::wstring Exception::GetWideMessage() const { using std::tr1::shared_ptr; shared_ptr<void> buff; LPWSTR buffPtr; DWORD bufferLength = FormatMessageW( FORMAT_MESSAGE_FROM_SYSTEM | FORMAT_MESSAGE_ALLOCATE_BUFFER | FORMAT_MESSAGE_IGNORE_INSERTS, NULL, GetErrorCode(), 0, reinterpret_cast<LPWSTR>(&buffPtr), 0, NULL); buff.reset(buffPtr, LocalFreeHelper()); return std::wstring(buffPtr, bufferLength); } ) does not work for HRESULTs. How do I generate these kinds of system-specific error strings for HRESULTs?

  • How do I stack Plack authentication handlers?

    - by Schwern
    I would like to have my Plack app try several different means of authorizing the user. Specifically, check if the user is already authorized via a session cookie, then check for Digest authentication and then fall back to Basic. I figured I could just enable a bunch of Auth handlers in the order I wanted them to be checked (Session, Digest, Basic). Unfortunately, the way that Plack::Middleware::Auth::Digest and Plack::Middleware::Auth::Basic are written they both return 401 if digest or basic auth doesn't exist, respectively. How is this normally dealt with in Plack?

  • Working with image pixels

    - by Mario
    Hey Guys, I'm trying to do a project here, which I want to implement the following: I have a rotation matrix and translation matrix are estimated, now I have an image in a certain location and I want to multiply all the image pixel by the rotation matrix and add the results to the translation matrix..... My issue is how to work with the pixels? I mean how to extract the pixel from the image in order to do the operation that I mentioned above? it's ok to give me the suggestion in either opencv or c++ *I need to know how to do this operation new_p(x,y) = old(x,y)* rotation_matrix + translation_matrix. I'm defining the image like that IplImage(), 3 channel image. For now I need to do the geometrical transformation* Thank you.

  • Is the use of union in this matrix class completely safe?

    - by identitycrisisuk
    Unions aren't something I've used that often and after looking at a few other questions on them here it seems like there is almost always some kind of caveat where they might not work. Eg. structs possibly having unexpected padding or endian differences. Came across this in a math library I'm using though and I wondered if it is a totally safe usage. I assume that multidimensional arrays don't have any extra padding and since the type is the same for both definitions they are guaranteed to take up exactly the same amount of memory? template<typename T> class Matrix44T { ... union { T M[16]; T m[4][4]; } m; }; Are there any downsides to this setup? Would the order of definition make any difference to how this works?

  • Tool To Catch All The Inputs That Cause Crash?

    - by Barakat
    Hi all, I need a Windows tool records inputs and debugging informations that cause program's crashing. I don't mean a fuzzing tool ! Ammmmm ... let me show you a scenario may explain what I'm talking about. Sometimes during using a program, It's crashed without known reason ! and when I want to debug it, I will not find helpful informations to know how the crash happened. Because that the data that cause the crash no longer exist. So I need a tool records all the inputs and debugging informations to find helpful informations to reuse the inputs data to make the program crashes under a debaucher in order to understand how the crash happen.

  • Qt: QAbstractItemModel and 'const'

    - by Eye of Hell
    Hello. I'm trying to use a QTreeView for a first time, with a QAbstractItemModel. And instantly it's a problem: QAbstractItemModel interface declares methods as 'const', assuming they will not change data. But i want a result of SQL query displayed, and returning data for a record with specified indeq REQUIRES to use QSqlQuery::seek() that is a non-const. Is it any 'official' guideline to use a QAbstractItemModel with data that MUST be changed in order to get number of items, data per item etc? Or i must hack C++ with const casts?

  • How to find out on which internet addresses a java program can listen.

    - by tzador
    My program needs to listen incoming socket connections (lets agree on port 8765), but it doesn't know which addresses it can bind on a particular machine. Of, course, it could simply to listen to all of them, but it need to send to the client program over a different(slower) channel the addresses which it should try in order to rich me on port 8765. So the flow is like this: My program lisens on all available interfaces on port 8765 Finds out a list of inet4 adresses by which it can be possibly reached (this step is the actual question) Posts that address on a whiteboard (blogpost or something) Interested clients try out all of them, to see using which one they can reach my program. This is all is to be done in java ofcourse :)

  • How to do rolling balances in Linq2SQL

    - by David Liddle
    Given an account with a list of transactions I would like to output a query that shows each transaction with the rolling balance (just like you would see on an online banking account). TRANSACTIONS - ID - DATE - AMOUNT Here is what I created in T-SQL however was wondering if this can be translated to linq2sql code? select T.ID, convert(char(10), T.DATE, 101) as 'DATE', T.AMOUNT, (select sum(O.AMOUNT) from TRANSACTIONS O where O.DATE < T.DATE or (O.DATE = T.DATE and O.ID <= T.ID)) 'BALANCE' from TRANSACTIONS as T where T.DATE between @pStartDate and @pEndDate order by T.DATE, T.ID Alternatively I guess my other option is to just call a stored procedure for these kind of results. However, I have Services which call Repositories and didn't really want to put the sproc call in the Repository.

  • What's a good FOSS java servlet session replication solution

    - by Bossy Joe
    I work on a very high volume public website running on Tomcat 5.5. Currently we require stickiness to a particular server in order to maintain session. I'd like to start replicating session, but have had trouble finding a good FOSS solution. I've written my own Manager (using memcached as the store) but am having trouble dealing with race conditions if more than one server is handling the requests for the same user. Is there a solution out there I should be looking at? I'm looking for not just something that works as a fallback if stickiness fails, but that would work if user requests are regularly spread to multiple servers.

  • Query to work out possible destinations on a set of routes using SQL Server 2008

    - by RobW
    I'm writing an application that models train routes, which are stored in the database table [TrainStop] as follows: RouteId StationCode StopIndex IsEnabled So a given route consists of several rows with the StopIndex indicating the order. The problem I am trying to solve is to say which stations a user can get to from a given starting station. This would be relatively straightforward BUT it is also possible to disable stops which means that a user cannot get to any destinations after that stop. It is also possible that multiple routes can share stations e.g.: Route 1: A, B, C, D, E Route2: P, Q, B, C, D, R So if a user is at B they can go to C, D, E and R but if station D is disabled they can get to C only. Solving this problem is fairly straightforward within C# but I am wondering whether it can be solved elegantly and efficiently within SQL? I'm struggling to find a way, for each route, to rule out stations past a row that is not enabled.

  • best way to filter out non-representational elements

    - by nonano
    Hi there, I am using phpQuery in order to apply some twaks to editorial content. As its syntax is the same as jQuery, I consider this a dom scripting issue. To get rid of elements which are not representing anything, but wrapping other stuff (like the div in <div><p>blah</p></div> I came up with this selector: ['div:not([align][class][id][style][title][dir][lang][onclick][ondblclick][onmousedown] [onmouseup][onmouseover][onmousemove][onmouseout][onkeypress][onkeydown][onkeyup])'] which looks quite monstrous for a selector simply aming on Divs which just do not have any (valid) attribute. I guess there must be a more straight-forward way to accomplish that, right? Edit: Oh, and I just noticed that it even doesn't do wat I intended to ...

  • VirtualBox: How to connect to Internet via wi-fi on Mac?

    - by Paul Riedel
    I installed VirtualBox with a Win XP VM on my Mac running OS 10.7.5. My Mac only has a wi-fi connection to the internet. On the settings for the virtual host, I set: Attached to: Bridged Adapter Name: en1: Wi-Fi (AirPort) Adapter Type: Intel PRO/1000 MT Desktop (82540EM) Promiscuous Mode: Deny Mac Address: Cable Connected: true Those are the settings I see around the internet as being correct, but I still can't ping anything. On my Mac I have internet sharing via Ethernet enabled (not sure if that matters). When I start up my WinXP VM, it asks me to install a bunch of hardware which I don't have any drivers to. Do I need to install any ethernet card drivers in order for the internet to work? Thank you!!

  • Jquery toggle using 2 elements

    - by user801773
    this is my script, I'm using a toggle so I can animate a sliding menu. $("div.show-menu").click().toggle( function() { // first alternation $("#slideover").animate({ right: "512px" }, 300); $(".menu-button").html('close menu'); }, function() { // second alternation $("#slideover").animate({ right: "0" }, 300); $(".menu-button").html('open menu'); }); Though I really need the toggle to work using 2 elements on the page. For example see below... <div class="show-menu one">open menu</div> // this is element one <div class="show-menu two">open menu</div> // this is element two I need it so, if element one get's click first, you can close the menu using element two on the first click. What is happening now is that you have to click element two twice in order for it to close the menu - vice versa I guess this is the toggle coming into play, any help would be great thanks. Cheers Josh

  • Translate SQL to LINQ query - group/join/filter

    - by Paddy
    I have the following query: SELECT S.[FlowOrder], S.[DESCRIPTION], COUNT(I.ID) FROM WorkFlowStatus AS S INNER JOIN Item AS I ON S.ID = I.StatusID WHERE I.Installation = '1' GROUP BY S.[Description], S.[FlowOrder] ORDER BY S.[FlowOrder] Which gives me the count of an item, grouped by a foreign key to workflow, outputting the descriptive name from my FK table. I've go this far with the LINQ query (using LINQ-to-SQL) in the background: var items = from s in _entities.WorkflowStatus join i in _entities.Items on s.ID equals i.StatusId into Statuses orderby s.FlowOrder select new {s.Description, ItemCount = Statuses.Count() }; How do I get the where clause in the SQL into this LINQ query?

  • Broken count(*) after adding LEFT JOIN

  • get n records at a time from a temporary table

    - by Claudiu
    I have a temporary table with about 1 million entries. The temporary table stores the result of a larger query. I want to process these records 1000 at a time, for example. What's the best way to set up queries such that I get the first 1000 rows, then the next 1000, etc.? They are not inherently ordered, but the temporary table just has one column with an ID, so I can order it if necessary. I was thinking of creating an extra column with the temporary table to number all the rows, something like: CREATE TEMP TABLE tmptmp AS SELECT ##autonumber somehow##, id FROM .... --complicated query then I can do: SELECT * FROM tmptmp WHERE autonumber>=0 AND autonumber < 1000 etc... how would I actually accomplish this? Or is there a better way? I'm using Python and PostgreSQL.
