• swipe to delete uitableview cell; a bit jumpy?

  - by Veeru

  I have implemented "swipe to delete" on my table cell. It works fine, how ever, the delete button is a little jumpy; as in, i really have to position my finger on top of the button and carefully touch it to delete the record. I am not sure if am making it clear; let me do my best to explain When the delete button appears; the user has trouble clicking on it, it disappears the moment its clicked. THe user has to try a few times to actually delete the cell. Am not sure what the reason is, it just seems like the delete button gets hidden as though the user has clicked on a different part of the cell. Any suggestsions?

• Where Should Using Statements Be Located [closed]

  - by Bobby Ortiz - DotNetBob

  Possible Duplicate: What is the difference between these two declarations? I recently started working on a project with using statement located inside the NameSpace block. namespace MyApp.Web { using System; using System.Web.Security; using System.Web; public class MyClass { I usually put my using statements above the namespace block. using System; using System.Web.Security; using System.Web; namespace MyApp.Web { public class MyClass { I don't think it matters, but I am currious if someone else had a recommendation and could they explain why one way is better than another. Note: I always have one class per file.

• C++ Arrays of Structure access

  - by learningtolive

  Hi, I'm studying C++ from Schildt's book and don't quite understand what does he mean under third structure; Can somebody explain this - To access a specific structure within an array of structures, you must index the structure name. For example, to display the on_hand member of the third structure, you would write cout cout << invtry[2].on_hand; Some code: struct type{ char item[40]; double cost; double retail; int on_hand; int lead_time; }invtry[SIZE];

• Tie destruction of an object (sealed) to destruction of an unmanaged buffer

  - by testtestSO

  I'll explain my situation first: I'm interested of using the Bitmap constructor that takes scan0, stride and format, because I'm decoding tiled images and I'd like to choose my own stride so I can decode the tiles without caring about the bounds in the decoder part. Anyway, the problem is that the documentation says: The caller is responsible for allocating and freeing the block of memory specified by the scan0 parameter. However, the memory should not be released until the related Bitmap is released. I can't release the buffer easily, because the Bitmap is then passed to another class that will eventually destroy it and I don't have control over it. Is there some way (hacky, I know) to tell the GC to also release my buffer when the Bitmap is destroyed? (Also, any alternative solution is welcome).

• .Net using Chr() to parse text

  - by Marcx

  I'm building a simple client-server chat system. The clients send data to the server and the server resends the data to all the other clients. I'm using the TcpListener and Network stream classes to send the data between the client and the server. The fields I need to send are, for example: name, text, timestamp, etc. I separate them using the ASCII character 29. I'm also using ASCII character 30 to mark the end of the streamed data. The data is encoded with UTF8.. Is this a good approach? Will I run into problems? Are there better methods? UPDATE: Probably my question was misunderstood, so I explain it better.. Suppose to have a list of data to send from client to server, and suppose to send all the data in only one stream, how do you send these data? Using a markup Using a character as a delimiter Using a fixed length for every fields

• Can a method return an NSRange?

  - by Dan Donaldson

  I have a method that returns an NSRange. When I call this method from outside the class I get a compile error. NSRange tmpRange; tmpRange = [phrase rangeInString:searchString forString:theLetter goingForward:YES]; return tmpRange.location == -1; in the .h file: #import <Foundation/Foundation.h> @interface Phrase : NSObject { } - (NSRange) rangeInString:(NSString *) tgt forString:(NSString *) find goingForward:(BOOL) fwd; @end This method is called within the Phrase object by other methods without problems. The compiler says 'incompatible types in assignment'. Can anyone explain this to me? I assume it has to do with returning an NSRange/struct type value generated outside the object, but I don't know why it works in one place and not the other.

  I tried to ask this question late lastnight but I was so sleepy i typed the question completely wrong. I'm looking to float my navigation to the right of its current position around 200px more, there is room but it wont move over. You can view the live code here - www.xronn.co.uk/hosting and here is an image to explain my issue a little more http://i.stack.imgur.com/JtL0C.png purple lines the 960px width of the site blue line shows the space free for the navigation to go and the red arrows of course shows which direction i want the navigation to go in (the right) Anyone got any clue why when I push to more to the right, the list starts to sit under each other

• Why do you sometimes need to write <typename T> instead of just <T> ?

  - by StackedCrooked

  I was reading the Wikipedia article on SFINAE and encountered following code sample: struct Test { typedef int Type; }; template < typename T > void f( typename T::Type ) {} // definition #1 template < typename T > void f( T ) {} // definition #2 void foo() { f< Test > ( 10 ); //call #1 f< int > ( 10 ); //call #2 without error thanks to SFINAE } Now I've actually written code like this before, and somehow intuitively I knew that I needed to type "typename T" instead of just "T". However, it would be nice to know the actual logic behind it. Anyone care to explain?

• I created a Python egg!!! Now... what do I do with it?

  - by froadie

  I've finally figured out how to create a Python egg and gotten it to work. Now... what do I do with it? How do I use it? How do I ensure that everything was correctly included? (Simple steps please... not just redirection to another site. I've googled, but it's confusing me, and I was hoping someone could explain it in a couple of simple bullet points or sentences.)

• Splitting values into groups evenly

  - by Paul Knopf

  Let me try to explain the situation the best I can. Lets say I have 3 values 1, 2, 3 I tell an algorithm to split this values into x columns. Lets say x = 2 for clarification. The algorithm determines that the group of values is best put into two columns the following way. 1st column 2nd column --------------------------- 1 3 2 Each column has an even number (totals, not literals) value. Now lets say I have the following values 7, 8, 3, 1, 4 I tell the algorithm that I want the values split into 3 columns. The algorithm now tells me that the following is the best fit. 1st column 2nd column 3rd column 8 7 3 1 4 Notice how the columns arent quiet even, but it is as close as it can get. A little over and a little under is considered ok, as long as the list is AS CLOSE TO EVEN AS IT CAN BE. Anybody got any suggestions? Know any good methods of doing this?

• NHibernate - Is ITransaction.Commit really necessary?

  - by user365383

  Hi I've just start studying NHibernate 2 days ago, and i'm looking for a CRUD method that i've writed based on an tutorial. My insert method is: using (ISession session = Contexto.OpenSession()) using (ITransaction transaction = session.BeginTransaction()) { session.Save(noticia); transaction.Commit(); session.Close(); } The complete code of "Contexto" is here: http://codepaste.net/mrnoo5 My question is: Do i really need to use ITransaction transaction = session.BeginTransaction() and transaction.Commit();? I'm asking this because i've tested run the web app without those two lines, and i've sucefully inserted new records. If possible, can someone explain me too the porpuse of Itransaction and the method Commit? Thanks

• the problem of redirecting stdout in c#

  - by Mher

  Could you please explain why the shell redirection doesn't work with System.Diagnostics.Process class? I am trying to redirect the output streams to file with the following snippet: Process p = new Process(); p.StartInfo = new ProcessStartInfo(); p.StartInfo.FileName = "java.exe"; p.StartInfo.Arguments = @"> c:\Temp\test.log 2>&1"; p.StartInfo.UseShellExecute = true; p.Start(); The similar code works without problems with Python. Reading the output streams programmatically doesn't seem a preferable solution in my case because there will be a bunch of processes launched by my application.

• An explanation of memory usage on Windows server 2003

  - by Rich

  Hi, We've been working on a bit of puzzle at work. We have an application service installed on two machines, both running Windows server 2003. These services do exactly the same thing. However once loaded, one of the services uses 200mb less than the other service. We're at a bit of a loss to what might be causing this discrepancy. I was wondering if there was some kind of server setting that would cause an application to use more memory (heap block size) or anything to explain this. If anyone has any ideas on what may be causing this, or how to find out what is causing this I'd be very grateful. Cheers Rich

• is the + in += on a Map a prefix operator of =?

  - by Steve

  In the book "Programming in Scala" from Martin Odersky there is a simple example in the first chapter: var capital = Map("US" -> "Washington", "France" -> "Paris") capital += ("Japan" -> "Tokyo") The second line can also be written as capital = capital + ("Japan" -> "Tokyo") I am curious about the += notation. In the class Map, I didn't found a += method. I was able to the same behaviour in an own example like class Foo() { def +(value:String) = { println(value) this } } object Main { def main(args: Array[String]) = { var foo = new Foo() foo = foo + "bar" foo += "bar" } } I am questioning myself, why the += notation is possible. It doesn't work if the method in the class Foo is called test for example. This lead me to the prefix notation. Is the + a prefix notation for the assignment sign (=)? Can somebody explain this behaviour?

• Impressing Potential Employers

  - by superfly123

  Where I am, I can't afford to get certification. I'm definitely not the best programmer, but I do know my junk. I've been writing software in C++ for over 8 years now and have a very good knowledge of the Win32 API. But when applying for jobs, I get rejected every time I send a resume. I've given my resume to recruitment firms and asked them what they think's wrong with it and they said the only thing they could think of is the fact that I don't have certifications to prove that I know my stuff. But in my resume, I explain my previous work and projects, and also note that upon request they can actually see what I've done. Is there anything that you would suggest that might help others to stop ignoring my resumes? Thank you

• what is the purpose of numeric/boolean/string objects as opposed to primitive values?

  - by zespri

  In javascript you can call a function as a function or as a constructor. For example you can do : myObject = new Number(13); myPrimitiveValue = Number(13); or simply myPrimitiveValue = 13; I understand the difference between the results. Can you explain me under which reasonable circumstances creating a number, a boolean or a string as an object is desirable? For example, ability to set new properties (this is something you can do on objects but can't really do on primitive values) is almost always a bad idea for objects containing number/boolean/string. Why would I want a numeric/boolean/string object?
