  • jquery: problem with unbinding mousenter() upon mouseup()

    - by Haroldo
    I'm building an interface for marking dates on a calendar as being booked. The user 'paints' on the dates they want to mark as booked. here's how it looks: here are the functions: function load_red_paint(){ $('td').bind('mousedown', function(){ $(this).addClass('booked'); $('td').bind('mouseenter', function(){ $(this).addClass('booked'); }); unbind_brush(); }) } function unbind_brush(){ $('td').bind('mouseup', function(){ $('td').unbind('mouseenter'); }); $('table').bind('mouseleave', function(){ $('td').unbind('mouseenter'); }); } the problem: My unbind_brush() function works great except for if the user mouseup's outside of the calendar, i tried to fix this my also unbinding on mouseleave of that calendar with this bit: $('table').bind('mouseleave', function(){ $('td').unbind('mouseenter'); }); but with no joy, am i missing something obvious?!!!

  • NSNumberFormatter crashing iPhone SDK 4.0b2

    - by Ward
    Hey there, I've got an app that's been in the app store for a while and functions perfectly on OS 3.1 - 3.13. However, when tested on 4.0b2 I noticed that it crashes in the same place every time, but only on the device, never on the simulator. I'm using a 3GS to test. On loadView I initialize an NSNumberFormatter object which is declared and retained in the interface so I have access to it everywhere. In my method I call it several times to convert string values into nsnumbers to be stored in a mutable dictionary. Here's an example: [myDictionary setObject:[myStyleFormatter numberFromString:@"1"] forKey:@"hours"]; [myDictionary setObject:[myStyleFormatter numberFromString:@"30"] forKey:@"minutes"]; [myDictionary setObject:[myStyleFormatter numberFromString:@"10"] forKey:@"seconds"]; For some reason it crashes as soon as it tries to set hours. The error is "attempt to insert nil value (key: hours)" Have I been doing something wrong all along? Has the api changed for 4.0b2? Thanks, Howie

  • TextToSpeech setOnUtteranceCompletedListener always returns -1 error?

    - by Robert Nekic
    I've been working with Android's TTS functions with general success however, one piece of it refuses to work for me; I can not successfully assign an OnUtteranceCompletedListener to my TextToSpeech object. I've tried implementing OnUtteranceCompletedListener in one of my classes and I've tried creating a new, stand-alone OnUtteranceCompletedListener instance. Both approaches are simple enough to implement and appear to yield proper listeners without exceptions...yet setOnUtteranceCompleteListener(myListener) ALWAYS returns -1 (ERROR). The documentation for this seems straight forward. Has anyone gotten this to work? I'm targeting SDK 4. Are there known issues with this with SDK4/v1.6?

  • Best Method for Minimizable Fullscreen Window

    - by kaykun
    Hi, I'm coding a short game in C++ and Win32, and I want to be able to make it in fullscreen with a fixed size. I also want the user to be able to switch focus between the game window and other windows as much as he/she wants without any weird screen glitches. So far I know of the ChangeDisplaySettings function and creating the window with the WS_POPUP style at initialization to make it fullscreen. To detect the user switching focus to other windows by way of alt+tab or otherwise, what messages should I be handling on the window's WndProc or should I be using another function? When loss of focus is detected should I only call ChangeDisplaySettings(NULL, 0); or are there other functions I should call as well? And what method should I use to handle focus back into the window? Also can anyone give me some info on how to make it work smoothly for different screen sizes? Thanks for any help.

  • Why won't the VisualVM Profiler profile my application?

    - by Luke
    I've created a simple 1 file java application that iterates through a loop, calls some functions, allocates some memory, adds some numbers, etc. I run that application via eclipse's Run As->Java Application. The running application shows up in Java VisualVM under Local. I double click on that application and go to the Profiler tab. The default settings are: Start profiling from classes: my.main.package.** Do not profile classes: java.*, javax.*, sun.*, sunw.*, com.sun.* I click on CPU. The CPU and Memory buttons gray out. Nothing happens. The Status says profiling inactive. When my application terminates the Status says application terminated. What am I doing wrong here? Are there some settings I need to tweak? Do I need to set a VM flag when I launch my application?

    I'm a new user of dynatree plugin. When I read the documentation, I found the list of tree and node class member functions, such as tree.getRoot(), node.countChildren().

  • ASP with Crystal Report 9 hangs on .NET framework 3.5

    - by Chris Yang
    We have an ASP (not ASP.NET) application running on Windows 2003 server. One of the functions of the application is to generate reports using Crystal Report 9. It has been working without any problem with .NET Framework 2.0 and now it is required to install .NET Framework 3.5 SP1 on the server but after we installed the 3.5 SP1, every time we run the application the Crystal report is not generated and the web page hangs so we have to recycle the application pool in IIS to get the application back going. Does anyone have any idea/solution to this problem? Any help will be greatly appreciate.

  • fast algorithm to sort very small set

    - by aaa
    hello. This is the problem I ran into long time ago. I thought I may ask your for your ideas. assume I have very small set of numbers (integers), 4 or 8 elements, that need to be sorted, fast. what would be the best approach/algorithm? my approach was to use the max/min functions only. At this point it becomes somewhat hardware dependent , so let us assume Intel 64-bit processor with SSE3 . Thanks

  • Using LINQ to SQL with multiple databases

    - by Stuart Ferguson
    I am working on a new project and hoping to use LINQ to SQL for the data access but have come across the following issue. I need to have my application access 3 databases with similar but not the same table structure, for example Database1 and Database 2 has a table called tblCustomer with 2 columns CustomerKey and CustomerName Database2 has a table called tblCustomer with 3 columns CustomerKey, CustomerName and CustomerPostCode I am looking for a solution that will allow me a query all three databases without the need for 3 GetCustomerList functions as Database1 and Database2 could use the same function as are the same structure, with an override function for database 3 to bring back the additional field. Is there a way i can declare a base datacontext class to handle Database 1 and 2 with an inherited version for Database 3. Thanks In Advance Stuart Ferguson

  • Data Structure Behind Amazon S3s Keys (Filtering Data Structure)

    - by dimo414
    I'd like to implement a data structure similar to the lookup functionality of Amazon S3. For those of you who don't know what I'm taking about, Amazon S3 stores all files at the root, but allows you to look up groups of files by common prefixes in their names, therefore replicating the power of a directory tree without the complexity of it. The catch is, both lookup and filter operations are O(1) (or close enough that even on very large buckets - S3's disk equivalents - both operations might as well be O(1))). So in short, I'm looking for a data structure that functions like a hash map, with the added benefit of efficient (at the very least not O(n)) filtering. The best I can come up with is extending HashMap so that it also contains a (sorted) list of contents, and doing a binary search for the range that matches the prefix, and returning that set. This seems slow to me, but I can't think of any other way to do it. Does anyone know either how Amazon does it, or a better way to implement this data structure?

  • Sharing memory among YACC, Lex, and C files

    - by sczizzo
    I have a YACC (Bison) grammar, a Lex (Flex) tokenizer, and a C program among which I need to share a struct (or really any variable). Currently, I declare the actual object in the grammar file and extern it wherever I need it (which is to say, my C source file), usually using a pointer to manipulate it. I have a shared header (and implementation) file between the C file and the grammar file with functions useful for manipulating my data structure. This works, but it feels a little uncomfortable. Is there a better way to share memory between the grammar and program?

  • Python 3: timestamp to datetime: where does this additional hour come from?

    - by Beau Martínez
    I'm using the following functions: # The epoch used in the datetime API. EPOCH = datetime.datetime.fromtimestamp(0) def timedelta_to_seconds(delta): seconds = (delta.microseconds * 1e6) + delta.seconds + (delta.days * 86400) seconds = abs(seconds) return seconds def datetime_to_timestamp(date, epoch=EPOCH): # Ensure we deal with `datetime`s. date = datetime.datetime.fromordinal(date.toordinal()) epoch = datetime.datetime.fromordinal(epoch.toordinal()) timedelta = date - epoch timestamp = timedelta_to_seconds(timedelta) return timestamp def timestamp_to_datetime(timestamp, epoch=EPOCH): # Ensure we deal with a `datetime`. epoch = datetime.datetime.fromordinal(epoch.toordinal()) epoch_difference = timedelta_to_seconds(epoch - EPOCH) adjusted_timestamp = timestamp - epoch_difference date = datetime.datetime.fromtimestamp(adjusted_timestamp) return date And using them with the passed code: twenty = datetime.datetime(2010, 4, 4) print(twenty) print(datetime_to_timestamp(twenty)) print(timestamp_to_datetime(datetime_to_timestamp(twenty))) And getting the following results: 2010-04-04 00:00:00 1270339200.0 2010-04-04 01:00:00 For some reason, I'm getting an additional hour added in the last call, despite my code having, as far as I can see, no flaws. Where is this additional hour coming from?

  • Problem using SQLDMO/Vb6 against SQL Server 2008

    - by E.J. Brennan
    I have a client, that uses SQLDMO for a portion of a custom application that was written against SQL Server 2000, and they recently upgraded to SQL Server 2008. The majority of the app still runs fine (doesn't use SQLDMO), but the admin functions which rely on SQLDMO stopped working. I installed the SQL2005 backward compatibility pack, and now SQLDMO partially works, i.e. I can run "select" type queries, but any "Update" queries fail with the error message: to connect to the server you must use SQL Server management studio or sql server management objects (SMO) Any thoughts? Should the backward compatibility pack give me ALL the functionality back, or is this a known issue? BTW: I realize SQLDMO has been deprecated and will go away next release, none-the-less I need to do what I can to solve the problem at hand.

  • is it possible to issue dynamic include in asp-classic?

    - by opensas
    I mean, like php'h include... something like my_file_to_be_included = "include_me.asp" -- for what I've seen so far, there are a couple of alternatives, but every one of them has some sort of shortcoming... what I'm trying to figure out is how to make a flexible template system... without having to statically include the whole thing in a single file with a loooooong case statement... here there are a couple of links a solution using FileSysmemObject, just lets you include static pages idem yet another one same thing from adobe this approach uses Server.Execute but it has some shortcomings I'd like to avoid... seems like (haven't tried yet) Server.Execute code runs in another context, so you can't use it to load a functions your are planning to use in the caller code... nasty... same thing I think this one is the same this looks promising!!! I'm not sure about it (couldn't test it yet) but it seems like this one dinamycally handles the page to a SSDI component... any idea???

  • Execute a function when a <link> element has finished loading

    - by nornagon
    I'm using jQuery Masonry to lay out my page, but I'm using a custom @font-face font. The problem being that Masonry doesn't know the metrics of the font until it's loaded. The Masonry docs suggest that you use $(window).load() instead of $(document).ready() to call the layout functions, but I don't want to have to wait until all the images etc. load. I can specify the dimensions of the images exactly, so Masonry doesn't need to wait until they're loaded. It's just the text that's the problem. How can I get jQuery to call a callback when the <link> element that links in the font finishes loading?

  • Why array size in llvm created by llvm's internal tools is not good enough for llvm?

    - by vava
    I'm getting strange error message from the following code: ArrayType * arrayType = ArrayType::get(Type::getInt32Ty(ctx), 0); stack = builder->CreateAlloca(arrayType, ConstantArray::get(arrayType, std::vector<Constant *>())); This code compiles fine but it gives me llvm::Value* getAISize(llvm::LLVMContext&, llvm::Value*): Assertion `Amt-getType() == Type::getInt32Ty(Context) && "Malloc/Allocation array size is not a 32-bit integer!"' failed. during execution. What's interesting, is that I never said of what type array size should be, it was created somewhere inside helper functions. So I naturally see no good reason for assert to be there. But I must be doing something wrong anyway, can you help me spot the problem? Thanks in advance. PS. LLVM, as good as it is, lacking documentation tremendously.

  • Android app (with felix) crashes with LinearAlloc exceeded capacity

    - by user1106000
    I am running apache felix and an osgi app on android (3.2). This works pretty well so far, but I have rather large chunks of data to load into the application (osgi bundles). The problem with that is that when I load the biggest chunk of data I get LinearAlloc exceeded capacity The error seems to come from LinearAlloc.c \#define DEFAULT_MAX_LENGTH (4*1024*1024) if (nextOffset > pHdr->mapLength) { /* * We don't have to abort here. We could fall back on the system * malloc(), and have our "free" call figure out what to do. Only * works if the users of these functions actually free everything * they allocate. */ LOGE("LinearAlloc exceeded capacity, last=%d\n", (int) size); dvmAbort(); } afaik in 3.2/4.x it is even 8*1024*1024, but I still hit that limit. I'm looking to get better insight on what causes this problem and how I might possibly be able to fix it. Any help would be appreciated.

  • JavaScript: Keeping track of eventListeners on DOM elements

    - by bobthabuilda
    What is the best way to keep track of eventListener functions on DOM elements? Should I add a property to the element which references the function like this: var elem = document.getElementsByTagName( 'p' )[0]; function clickFn(){}; elem.listeners = { click: [clickFn, function(){}] }; elem.addEventListener( 'click', function(e){ clickFn(e); }, false ); Or should I store it in my own variable in my code like below: var elem = document.getElementsByTagName( 'p' )[0]; function clickFn(){}; // Using window for the sake of brevity, otherwise I wouldn't =D // DOM elements and their listeners are referenced here in a paired array window.listeners = [elem, { click: [clickFn, function(){}] }]; elem.addEventListener( 'click', function(e){ clickFn(e); }, false ); Obviously the second method would be less obtrusive, but it seems it could get intensive iterating through all those possibilities. Which is the best way and why? Is there a better way?

  • JavaScript setTimeout setInterval within one function

    - by dagoof
    I think I might be overtired but I cannot for the life of me make sense of this, and I think it's due to a lack of knowledge of javascript var itv=function(){ return setInterval(function(){ sys.puts('interval'); }, 1000); } var tout=function(itv){ return setTimeout(function(){ sys.puts('timeout'); clearInterval(itv); }, 5500); } With these two functions I can call a=tout(itv()); and get a looping timer to run for 5.5 seconds and then exit, essentially. By my logic, this should work but it simply is not var dotime=function(){ return setTimeout(function(){ clearInterval(function(){ return setInterval(function(){ sys.puts("interval"); }, 1000); }); }, 5500); } any insight in this matter would be appreciated.

  • Dynamic query runs directly but not through variable, what could be the reason?

    - by waheed
    Here is my scenario, I'm creating a dynamic query using a select statement which uses functions to generate the query. I am storing it into a variable and running it using exec. i.e. declare @dsql nvarchar(max) set @dsql = '' select @dsql = @dsql + dbo.getDynmicQuery(column1, column2) from Table1 exec(@dsql) Now it produces the many errors in this scenario, like 'Incorrect syntax near ','' and 'Case expressions may only be nested to level 10.' But if i take the text from @dsql and assign it a variable manually like: declare @dsql nvarchar(max) set @dsql = '' set @dsql = N'<Dynamic query text>' exec(@dsql) it runs and generates the result, what could be the reason for that ?? Thanks..

  • Python and App Engine project structure

    - by Joel
    Hello, I am relatively new to python and app engine, and I just finished my first project. It consists of several *.py files (usually py file for every page on the site) and respectively temple files for each py file. In addition, I have one big PY file that has many functions that are common to a lot of pages, in I also declared the classes of db.Model (that is the datastore kinds). My question is what is the convention (if there is one) of arranging these files. If I create a model.py with the datastore classes, should it be in different package? Where should I put my template files and all of the py files that handle every page (should they be in the same directory as the one big common PY file)? I have tried to look for MVC and such implementations online but there are very few. Thanks, Joel

  • Interchanging presentModalViewController and pushViewController

    - by Neffster
    I am using a sample ViewController that is displayed in the sample program as a presentModalViewController. However, I want to use pushViewController on the UIViewController instead. The problem is that when I switch to pushViewController, the ViewController no displays properly. Functions in the ViewController are called, but I don't see anything. I change back to presentModalViewController and everything works. The question is what do I need to do to make pushViewController work? FCVC *fcVC; NSArray *array = [[NSBundle mainBundle] loadNibNamed:@"fcVC" owner:self options:nil]; fcVC = [array objectAtIndex:0]; A. [self presentModalViewController:fcVC animated:YES]; // "WORKS" or B. [self.navigationController pushViewController:fcVC animated:YES]; // "Doesn't work
