• Positioning divs inside a container div without the content of an upper div affecting the position o

  - by silverCORE

  Hi. I'm trying to accomplish the following layout, and I'm almost there, except for the last green div, which is going lower and lower depending on the content of the content (white) div. If I set a value for the TOP property for the green div, and then I add some more text to the content div, the green div goes lower and lower. Since the green div is child to the main container div, and the green div is relatively positioned, isn't it supposed to be placed specifically at the position indicated by the TOP value of it? If I'm incorrect...can someone please tell me how can i make it so that the green div is always displayed at the same spot within the container (gray) div, regardless of the height of the content/white div? I tried to paste the css code here but was having problems with the brower. you can see the test site source/css at http://www.rae-mx.com/test tia for the help.

• iphone - compiler conditional on header

  - by Mike

  I have a project that generates applications for two targets. One of the targets has to include one additional delegate protocol that should not be present on the other one. So, I have created a macro on Xcode and declared the header like this: #ifdef TARGET_1 @interface myViewController : UIViewController <UIScrollViewDelegate, UIPopoverControllerDelegate> #endif #ifdef TARGET_2 @interface myViewController : UIViewController <UIScrollViewDelegate> #endif { .... bla bla.... } The problem is that Xcode is not liking this "double" declaration of @interface and is giving me all sort of problems. How to solve that? thanks for any help.

• Detect if a table contains a column in Android/sqlite

  - by sandis

  So I have an app on the market, and with an update I want to add some columns to the database. No problems so far. But I want to detect if the database in use is missing these columns, and add them if this is the case. I need this to be done dynamically and not just after the update to the new version, because the application is supposed to still be able to import older databases. Normally I would be able to use the PRAGMA query, but Im not sure how to do this with Android. I cant use execSQL since it is a query, and I cant figure out how to use PRAGMA with the query()-function. Ofcourse I could just catch exceptions and then add the column, or always add the columns to each table before I start to work with it, but that is not a neat solution. Cheers,

• PHP-GD: Dealing with Unicode characters

  - by sehugg

  I am developing a web service that renders characters using the PHP GD extension, using a user-selected TTF font. This works fine in ASCII-land, but there are a few problems: The string to be rendered comes in as UTF-8. I would like to limit the list of user-selectable fonts to be only those which can render the string properly, as some fonts only have glyphs for ASCII characters, ISO 8601, etc. In the case where some decorative characters are included, it would be fine to render the majority of characters in the selected font and render the decorative characters in Arial (or whatever font contains the extended glyphs). It does not seem like PHP-GD has support for querying the font metadata sufficiently to figure out if a character can be rendered in a given font. What is a good way to get font metrics into PHP? Is there a command-line utility that can dump in XML or other parsable format?

• MVVM - RaisePropertyChanged turning code into a mess

  - by vidalsasoon

  New to MVVM so please excuse my ignorance. I THINK i'm using it right but I find my ViewModel has too many of these: RaisePropertyChanged("SomeProperty") Every time I set a property I have to raise that damned property changed. I miss the days where I could just go: public int SomeInteger { get; private set;} These days I have to stick the "RaisePropertyChanged" in everywhere or my UI does not reflect the changes :( Am I doing it wrong or are other people getting annoyed with the excessive number of magic strings and old school property setters? Should I be using dependency properties instead? (I doubt that would help the code bloat anyway) Despite these problems I still think MVVM is the way to go so I guess that's something.

• RavenDB-Embedded Unstable In Cooperation With ASP .Net Web API Using 2-Tier Architecture

  - by Mohsen Alikhani

  My application is used RavenDB-Embedded Unstable 1.2.2127 that it's intracted with ASP .Net Web API in the separated assemblies. When I use "UseEmbeddedHttpServer = true" on the document store, first time I send a request to RavenDB, it executes properly but when I try for the second time my application displays Raven Studio. However, if UseEmbeddedServer setting be removed then my application will be running without any problems. My RavenDB is configured with the following codes in data tier : this.documentStore = new EmbeddableDocumentStore { ConnectionStringName = "RavenDB", UseEmbeddedHttpServer = true } and implementation of Web.config have these settings in the service tier : <connectionStrings> <add name="RavenDB" connectionString="~\App_Data\RavenDatabase" /> </connectionStrings> Is there a setting I missed?

• Are jQuery and GWT comparable frameworks?

  - by lomaxx

  At work there's a bit of discussion around what client side framework we should use for our front end web applications. Currently it's a showdown between GWT and jQuery and I'm kind of on the fence but leaning towards jQuery. From what I can tell, GWT and jQuery are trying to solve different problems but are compared to each other because they both end up existing in the web applications space. I suspect that if this is the case, then comparing the two may be fruitless so what I'm trying to get my head around is if comparing jQuery to GWT is even an apples to apples comparison in the same way that jQuery and ExtJS can be compared, or would it be more beneficial for our team to ask certain questions of our application and use the answers to determine which framework is a better fit for us?

  - by Mo Boho

  Using javascript, how can we auto insert the current DATE and TIME into a form input field. I'm building a "Problems" form to keep track of user submitted complaints about a certain service. I'm collecting as much info as possible. I want to save the staff here from having to manually enter the date and time each time they open the form. I have this snippet of code: <input id="date" name="date" value="javascript:document.write(Date()+'.')"/> but it's not working. many thanks for any help.

• VCL/Delphi/BCB - which IDE/language should I use?

  - by mawg

  I bought Delphi 1 when it came out - and was hooked. When BCB came out (around D3, iirc), I switched, mainly because I have used C/C++ professionally for a few decades. I have "been away" for 7 or 8 years and am now returning. I still have BCB 6 & Delphi 7 (not to mention Kylix). I always felt more comfortable with C++ than Pascal - purely because of work-day familiarity. But, realistically, iirc, most 3rd party VCL components are coded in Delphi/Pascal. And I think I used to have problems debugging Delphi components from BCB, but I could well remember wrongly. Anyhoo, now I am back and intend to use VCL components / hack the code of same / debug them & code a few of my own. Given that I am slightly more comfortable with C++, is there any compelling reason to choose Delphi over BCB, or is this just a case of how long my particular piece of string is?

• How to build sqlite for Python 2.4?

  - by Verrtex

  I would like to use pysqlite interface between Python and sdlite database. I have already Python and SQLite on my computer. But I have troubles with installation of pysqlite. During the installation I get the following error message: error: command 'gcc' failed with exit status 1 As far as I understood the problems appears because version of my Python is 2.4.3 and SQLite is integrated in Python since 2.5. However, I also found out that it IS possible to build sqlite for Python 2.4 (using some tricks, probably). Does anybody know how to build sqlite for Python 2.4? As another option I could try to install higher version of Python. However I do not have root privileges. Does anybody know what will be the easiest way to solve the problem (build SQLite fro Python 2.4, or install newer version of Python)? I have to mention that I would not like to overwrite the old version version of Python. Thank you in advance.

  I'm trying to setup a Git server on Windows 7, using CopSsh, PuTTY and msysgit. I'm having problems cloning a repository using ssh.

• Recursive TreeView in C# ASP.NET

  - by waqasahmed

  I have an object of type list from which I wish to use to populate a treeview in asp.net c#. Each object item has: id | Name | ParentId so for example: id | Name | ParentId 1 | Alice | 0 2 | Bob | 1 3 | Charlie | 1 4 | David | 2 In the above example, the parent would be Alice having two children Bob and Charlie. David is the child of Bob. I have had many problems trying to dynamically populate the treeview recursively in c# ASP.NET Does any one have a simple solution? Btw: you can use People.Id, People.Name and People.ParentId to access the members since it is an object belonging to list. I can post you my code so far (many attempts made) but not sure how useful it will be.

• What is the purpose of Managers / Transactions?

  - by maxdj

  I'm building a spring application for the first time. I'm running into lots of problems with concurrency, and I suspect that there is something wrong with the way I'm managing the backend. The only difference I can see between my backend code and examples I've seen are manager classes. In my code, I have my model (managed by hibernate) and my DAOs on top of that to do CRUD/searching/etc on the models. In example code I have looked at, they never use the DAO directly. Instead, they use manager classes that call the DAOs indirectly. To me, this just seems like pointless code duplication. What are these manager classes for? I've read that they wrap my code in "transactions," but why would I want that?

• How to detect code duplication during development ?

  - by David Dibben

  We have a fairly large code base, 400K LOC of C++, and code duplication is something of a problem. Are there any tools which can effectively detect duplicated blocks of code? Ideally this would be something that developers could use during development rather than just run occasionally to see where the problems are. It would also be nice if we could integrate such a tool with CruiseControl to give a report after each check in. I had a look at Duploc some time ago, it showed a nice graph but requires a smalltalk environment to use it, which makes running it automatically rather difficult. Free tools would be nice, but if there are some good commercial tools I would also be interested.

• Scheme homework problem, need help.

  - by poorStudent

  Okay one of my homework problems is to take a list of lists and return the car of each sublist as a list. I have it to where I can print out the values, but it's not a list. To be honest, I have no clue how to output lists. Here's what I got: (define (car-print alist) (if (null? alist) (newline) (begin (write (car (car alist))) (display " ") (car-print(cdr alist))))) This is a cheap way to do it, perhaps some help on actually solving this problem would be much appreciated. Not necessarily the full answer but steps to get there. Thanks.

• Proper way of utilizing gearman with my php application.

  - by luckytaxi

  For now I just want to use Gearman for background processing. For example, I need to email a recipient that they have a private message waiting for them once the sender submits their message into the DB. I assume I can run the worker/client and server on my primary server but I have no problems offloading some of the tasks to a different web server. Anyways, my question is how do I handle multiple "functions?" Let's say I need a job that handles the email portion and a job to handle image manipulation. Can I have multiple functions in the worker? I've followed a couple of examples I found online but each example only shows one function being initialized. Do I have to start up multiple "workers" to handle multiple functions?

• Data validate tools (ETL tools) for SQL server

  - by Stan

  I have some data in Excel and need to import into database. Is there any tool that can validate and maybe clean the data? Does Red Gate have such tool? The input will be Excel. Given table constraints, eg. CHECK, UNIQUE KEY, datetime format, NOT NULL. Desire output should be as least shows which lines are having problems, and then fix some trivial error automatically, like fill in default value for NULL columns, automatically correct datetime format. I know using Python can build such a script. But just wonder what's the popular way to do this. Thanks.

• 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.

• How do people prove the correctness of Computer Vision methods?

  - by solvingPuzzles

  I'd like to pose a few abstract questions about computer vision research. I haven't quite been able to answer these questions by searching the web and reading papers. How does someone know whether a computer vision algorithm is correct? How do we define "correct" in the context of computer vision? Do formal proofs play a role in understanding the correctness of computer vision algorithms? A bit of background: I'm about to start my PhD in Computer Science. I enjoy designing fast parallel algorithms and proving the correctness of these algorithms. I've also used OpenCV from some class projects, though I don't have much formal training in computer vision. I've been approached by a potential thesis advisor who works on designing faster and more scalable algorithms for computer vision (e.g. fast image segmentation). I'm trying to understand the common practices in solving computer vision problems.

• Boost graph libraries: setting edge weight values

  - by AndyUK

  I am investigating the use of the boost graph libraries in order to apply them to various network problems I have in mind. In the examples I have been looking at the graph edge values ("weights") are always initialized as integers, such as in these Bellman-Ford and Kruskal algorithms eg: int weights[] = { 1, 1, 2, 7, 3, 1, 1, 1 }; My problem is if I try and change the weights to double, I get a heap of warning messages about conversions etc, which so far I have not been able to figure out how to overcome. Does anyone see a way around this?

• ReadOnly Property in Custom Column Types in Sharepoint

  - by Ray Booysen

  Hey all I'm creating a custom column in a feature for Sharepoint. It is essentially this: <Field Type="Integer" ID="<insert guid here>" ReadOnly="true" Name="xxx" DisplayName="XXX" Group="YYY" /> When the field is deployed and attached to a content type, the content type shows no instance of this field being attached. The documentation about ReadOnly is a bit vague but definitely states that the column will be available for viewing in a View. However, when I create a view it is not available. The moment I remove ReadOnly from the field, it is available on the content type without any problems. Any ideas?

• C# .net -> SQLite error: Unable to open the database file

  - by CODe

  Hello all, I'm getting "System.Data.SQLite.SQLiteException: Unable to open the database file." when I attempt to access the database to save a record upon the "first" opening of my program. Here's the thing, it works fine when debugging locally in Visual Studio, but stops working when I package the program in an installer, and then install the program somewhere. I was guessing that it was the location of the database, which I just have set at database.s3db without a path, because it is stored next to the program's exe, but how could that cause problems? I'm at a loss, any further ideas or suggestions for solving this problem would be greatly appreciated.
