• A PHP object server for business logic

  - by Matthieu

  I wonder if such a thing is possible or even exist : In the MVC pattern, I would like to have the Model part to be persistant in memory, instead of reloading my instances at each execution. So I want only the Controller and View part to be executed. Is there any solution of server that would provide PHP objects (just like a Mysql server provides data records), and that keeps these objects in memory ? A problem would be also : how to have a constructed query to get objects ? Maybe PHP Linq ?

• Adding image to navigation bar

  - by 4thSpace

  I'd like an image to take up all of a navigation bar. This is the navigation that comes with a navigation based app. It appears on the RootViewController with the accompanying UITableView. I've seen some examples of how this might work. Set navigation bar title: UIImage *image = [UIImage imageNamed:@"TableviewCellLightBlue.png"]; UIImageView *imageView = [[UIImageView alloc] initWithImage:image]; [self.navigationController.navigationBar.topItem setTitleView:imageView]; The problem there is it only covers the title rather than the entire navigation bar. There is also this thread: http://discussions.apple.com/message.jspa?messageID=9254241#9254241. Towards the end, the solution looks to use a tab bar, which I'm not using. It is that complicated to set a navigation bar background? Is there some other simpler technique? I'd like to have a background for the navigation and still be able to use title text.

• Implementing sub fields in a PropertyGrid

  - by evolve

  Alright so my terminology when it comes to C# isn't great, so I'll attempt to explain this with a small example. If you create a class which you are using within a PropertyGrid and you have the following values: class Test { public Point example { get; set; } } This will produce a PropertyGrid which has an expandable object "example" which has fields X and Y in order to create a "Point". I'm attempting to create an object "name" which has fields "firstname" and "lastname", so I have: class Test { public Name example { get; set; } } public struct Name { public string firstname { get; set; } public string lastname { get; set; } } This however isn't working as intended. I think I need to override some method(s) in order to get this working, however since I don't really have the terminology down for PropertyGrids it is difficult for me to find a solution. Any help would be great.

• How to flush output after each `echo` call?

  - by CuSS

  Hi all! I've a php script that only produces logs to the client. When I echo something, i wan't it to be transfered to client on-the-fly. (Because while the script is processing, the page is blank) I had already played arround with ob_start() and ob_flush(), but they didn't worked. What's the best solution? PS: it is a little dirty to put a flush at the end of the echo call... EDIT: Neither the Answers worked, PHP or Apache Fault? Thanks in advance, José Moreira Sorry for my bad English. ;)

• Combining DROP USER and DROP DATABASE with SELECT .. WHERE query?

  - by zsero

  I'd like to make a very simple thing, replicate the functionality of mysql's interactive mysql_secure_installation script. My question is that is there a simple, built-in way in MySQL to combine the output of a SELECT query with the input of a DROP user or DROP database script? For example, if I'd like to drop all users with empty passwords. How could I do that with DROP USER statement? I know an obvious solution would be to run everything for example from a Python script, run a query with mysql -Bse "select..." parse the output with some program construct the drop query run it. Is there an easy way to do it in a simple SQL query? I've seen some example here, but I wouldn't call it simple: http://stackoverflow.com/a/12097567/518169 Would you recommend making a combined query, or just to parse the output using for example Python or bash scripts/sed?

• Script.PostDeployment.sql not executing in CI build VS 2010

  - by Suirtimed

  I have a database project in VS 2010 (SQL 2008). The local Deploy Solution action works and executes all of the SQL in the Script.PostDeployment.sql file. When I check changes in, the Build Definition for the continuous integration server executes. The database is deployed into the CI environment, but the PostDeployment script doesn't get executed. I wasn't able to find anything specific to this particular scenario. I also expect I'll need to provide additional information unless this is a trivial problem that I missed somewhere. Additional Information: The build is executing vsdbcmd.exe to deploy. The deployment manifest references the PostDeployment.sql file and it's present in the path with the rest of the files. Here is a reference to a thread on social.msdn.microsoft.com regarding this problem.

• Delphi for PHP - location of source

  - by Holgerwa

  I just installed Delphi for PHP to get an idea on how it works and have created a simple app with a button that puts a text into a listbox when it is clicked. The app works if I copy all required files to my webserver and run it from there. It also works if I save the project in the standard path: "c:\documents and settings\username\My Documents\Delphi for PHP Projects" But if I save the project in another directory, the ButtonClick event is not fired when the application runs from there. I've put a breakpoint in the event to see if it stops there but it doesn't. The OnShow event of the form works as usual. It really seems to be the path where the project is located to make it either work or not. As I said, I have no experience with Delphi for PHP so far, it is probably just a simple solution that I don't see...

• Is there a pattern that allows a constructor to be called only from a specific factory and from nowh

  - by willem

  We have a class, say LegacyUserSettingsService. LegacyUserSettingsService implements an interface, IUserSettingsService. You can get an instance of the IUserSettingsService by calling our ApplicationServicesFactory. The factory uses Spring.NET to construct the concrete LegacyUserSettingsService. The trouble is that new developers sometimes do their own thing and construct new instances of the LegacyUserSettingsService directly (instead of going via the factory). Is there a way to protect the constructor of the concrete class so it can only be called from the factory? A well-known pattern perhaps? Note that the concrete class resides in a different assembly (separate from the Factory's assembly, so the internal keyword is not a solution). The factory assembly references the other assembly that contains the concrete class. Any ideas?

• Screen scraping an application window and interacting with the mouse and keyboard

  - by ccook

  The other day I found myself addicted to a flash game and frustrated by the thing at the same time. In a moment of frustration with the game I thought I would make a 'bot' to beat it for me. Well, I really wouldn't, but it made me realize: I don't know how to interact with another application in a way to do this. Which brings me to the question, how would one take screenshots of another running application and interact with it with the keyboard and mouse. Ideally the solution would be in a managed language like c#. When doing the background reading the net was drowning with articles on scrapping HTML. There were not many articles on actually screen scrapping an application. Diverse answers are appreciated as I’m really looking at surveying what’s out there.

• Java library for converting Word documents to PDFs or images

  - by mieze

  Hey there What I need to do is convert Microsoft Word .doc files to PDFs or images. This has to occur in Java. I have done a fair bit of investigation already. I've tried Davisor Publishor but it doesn't give me the accuracy that I need - for instance text overlapping in the output document. Adobe has something called LiveCycle. Anyone tried this? It looks quite massive and a bit of overkill (its an "integrated server solution"). Sounds expensive. Saying that, it doesn't have to be free, or cheap. Even if you just know some names, please shout them my way. Many thanks in advance. Doug

• Interface(s) inheriting other interface(s) in WCF services.

  - by avance70

  In my solution there's a few WCF services, each of them implementing it's own callback interface. Let's say they are called: Subscribe1, with ISubscribe1 and ICallback1, etc. It happens there are a few methods shared among ICallbacks, so I made a following interface: interface ICallback { [OperationContract] CommonlyUsedMethod(); } and i inherited it in all: ICallback1 : ICallback, ICallback2 : ICallback, etc. And deleted the CommonlyUsedMethod() from all callback interfaces. Now, on the service-side code, everything compiles fine and services can start working as usual. But, when I updated the service references for the client, CommonlyUsedMethod() dissapeared from the reference.cs file (the ISubscribeCallback part), and could no longer be used to send data to back to the client.

• Array in Bash Not Found

  - by Waffle

  I am trying to declare an array in bash, but when the code is run it says it cannot find the array. I have tried to write out the declaration of the array in several different ways, but it seems no matter how I try to declare it I cannot get it to work. I originally tried to declare it as such: candidate[1]= 0 candidate[2]= 0 candidate[3]= 0 The error messages that are returned are: votecalculation.sh: 13: candidate[1]=: not found votecalculation.sh: 14: candidate[2]=: not found votecalculation.sh: 15: candidate[3]=: not found After this I tried another solution I found online: ARRAY=( 'can1' 'can2' 'can3' ) When that is used it returns this error: votecalculation.sh: 12: Syntax error: "(" unexpected I am new to Bash and am getting really confused about arrays. Is there some specific way I need to declare an array or am I just going about it completely wrong?

• Why are types found on an imported namepace but not on a fully qualified namespace after retargeting the framework?

  - by Paul Ferguson

  We've just re-targeted a VB.NET project from .Net 2.0 to 3.5. Various framework types are now missing from our project. Wherever the type is referenced using a fully qualified namespace it's missing. If the relevant namespace is imported for the type; it's found. For example, this doesn't find the type Object, with compiler error "System.Object is not defined.": Public Class Foo Inherits System.Object End Class However, this works ok: Imports System Public Class Foo Inherits [Object] End Class I've already tried re-opening the solution with no success.

• Limiting the number of threads executing a method at a single time.

  - by Steve_

  We have a situation where we want to limit the number of paralell requests our application can make to its application server. We have potentially 100+ background threads running that will want to at some point make a call to the application server but only want 5 threads to be able to call SendMessage() (or whatever the method will be) at any one time. What is the best way of achieving this? I have considered using some sort of gatekeeper object that blocks threads coming into the method until the number of threads executing in it has dropped below the threshold. Would this be a reasonable solution or am I overlooking the fact that this might be dirty/dangerous? We are developing in C#.NET 3.5. Thanks, Steve

• Google Calendar API DoS prevention

  - by Don

  Hi, It appears that the Google calendar API effectively locks you out if you create and delete a few (less than 10) calendars within a short space of time. This has made it basically impossible for me to test my app, because it creates/deletes a calendar for each user that is added/removed from the app. Currently, I'm "working around" this issue by creating a new Google account each time I get locked out of the Calendar API. Clearly, this solution is less than satisfactory. Is there any way I can avoid this over-zealous DoS prevention? Thanks, Don

• Converting between unsigned and signed int safely

  - by polemic

  I have an interface between a client and a server where a client sends (1) an unsigned value, and (2) a flag which indicates if value is signed/unsigned. Server would then static cast unsigned value to appropriate type. I later found out that this is implementation defined behavior and I've been reading about it but I couldn't seem to find an appropriate solution that's completely safe? I've read about type punning, pointer conversions, and memcpy. Would simply using a union type work? A UnionType containing signed and unsigned int, along with the signed/unsigned flag. For signed values, client sets the signed part of the union, and server reads the signed part. Same for the unsigned part. Or am I completely misunderstanding something? Side question: how do I know the specific behavior in this case for a specific scenario, e.g. windriver diab on PPC? I'm a bit lost on how to find such documentation.

• Referencing a theorem-like environment by its [name]

  - by Seamus

  I am using ntheorem to typeset a set of conditions. In my preamble I have: \theoremstyle{empty} \newtheorem{Condtion}{Condtion} When I want to typeset a condition, I write: \begin{Condtion}[name] \label{cnd:nm} foo foo foo \end{Condition} The name appears boldface on the same line as the start of the text of the condition, with no number or anything. Perfect. What I want to do now is refer to the condition by some variant of the \ref command, \ref calls the number [which is not displayed anywhere else] \thref writes "Condition n" for the nth condition \nameref writes the name of the SECTION of the label. a zref solution was suggested here, but seems unsatisfactory. Any clues?

• Dot Game and Dynamic Programming

  - by Albert Diego

  I'm trying to solve a variant of the dot game with dynamic programming. The regular dot game is played with a line of dots. Each player takes either one or two dots at their respective end of the line and the person who is left with no dots to take wins. In this version of the game, each dot has a different value. Each player takes alternate turns and takes either dot at either end of the line. I want to come up with a way to use dynamic programming to find the max amount that the first player is guaranteed to win. I'm having problems grasping my head around this and trying to write a recurrence for the solution. Any help is appreciated, thanks!

• Timeout LinqToSql inserting millions of records

  - by Bas

  I'm inserting approximently 3 million records in a database using this solution. Eventually when the application has been inserting records for a while (my last run lasted around 4 hours), it gives a timeout with the following SqlException: "SqlExcepetion: Timeout expired. The timeoutperiod elapsed prior to completion of the operation or the server is not responding." What's the best way to handle this exception? Is there a way to prevent this from happening or should I catch the exception? Thanks in advance!

• How to format a string as a telephone number in C#

  - by Brian G

  I have a string "1112224444' it is a telephone number. I want to format as 111-222-4444 before I store it in a file. It is on a datarecord and I would prefer to be able to do this without assigning a new variable. I was thinking: String.Format("{0:###-###-####}", i["MyPhone"].ToString() ); but that does not seem to do the trick. ** UPDATE ** Ok. I went with this solution Convert.ToInt64(i["Customer Phone"]).ToString("###-###-#### ####") Now its gets messed up when the extension is less than 4 digits. It will fill in the numbers from the right. so 1112224444 333 becomes 11-221-244 3334 Any ideas?

• iOS: How to access the `UIKeyboard`?

  - by MattDiPasquale

  I want to get a pointer reference to UIKeyboard *keyboard to the keyboard on screen so that I can add a transparent subview to it, covering it completely, to achieve the effect of disabling the UIKeyboard without hiding it. In doing this, can I assume that there's only one UIKeyboard on the screen at a time? I.e., is it a singleton? Where's the method [UIKeyboard sharedInstance]. Brownie points if you implement that method via a category. Or, even more brownie points if you convince me why it's a bad idea to assume only one keyboard and give me a better solution.

• advanced python autovivification

  - by Zhang18

  This question is about implementing the full PERL autovivification in python. I know similary questions were asked before and so far the best answre is http://stackoverflow.com/questions/635483/what-is-the-best-way-to-implement-nested-dictionaries-in-python/652284#652284. However, I'm looking to do this: a['x']['y'].append('z') without declaring a['x']['y'] = [] first, or rather, not declaring a['x'] = {} either. I know dict and list classes sorta don't mix so this is hard, but I'm interested in seeing if someone has an ingenius solution probably involving creating an inherited class from dict but defined a new append method on it? I also know this might throw off some python purists who will ask me to stick with Perl. But even just for a challenge, I'd like to see something. thx!

• What's a better way to display a handle for resizing a view on iPhone / iPad?

  - by Christian

  I want to display a handle at the corners of a UIView that can be used to resize the view. How can I display the handles floating on the top of everything else and still have a connection to and be in sync with a view? The solution I implemented before looks like this: I put the view into another view that shows the handles on top of the corners. The problem with this approach is that the handles add extra space to the original view's size. Since Apple recommends at least 40 x 40 px for the size of a button, it is not very little space and also goes beyond the visible bounds of the original view. Another problem is that the original view has to be encapsulated in this 'helper view' object and thus becomes a part of something although it really is the main component.

• GWT application not displaying data on Windows 7 Starter Edition

  - by Steve Buikhuizen

  I have a GWT application that works great on all platforms/browsers etc. Then we tried Windows 7 Starter Edition. For all browsers (Chrome, IE, Firefox) none of the dynamically displayed data appears in the application. We know that the machine is ok because Google Wave works fine and its also a GWT application. I'm at a loss. What could cause this to happen? I'd be grateful if you have a suggestion as to how to debug this. If so find the solution I'll post it.
