  • comparison between point and integer

    - by LawVS
    Right, basically I want to add two numbers together. It's for a working hours calculator and I've included parameters for a night shift scenario as an if statement. However, it now mucks up the day shift pattern. So I want to sort out that if the start time is below 12, then it'll revert to the original equation shown in the code instead of the if statement. -(IBAction)done:(id)sender { int result = [finishHours.text intValue] - [startHours.text intValue]; totalHours.text = [NSString stringWithFormat:@"%d", result]; if (result < 0) { totalHours.text = [NSString stringWithFormat:@"%d", result * -1]; } if (result < 12) { totalHours.text = [NSString stringWithFormat:@"%d", result + 24]; } if (startHours < 12) { totalHours.text = [NSString stringWithFormat:@"%d", result - 24]; }

  • What's the difference between => , ()=>, and Unit=>

    - by Malvolio
    I'm trying to represent a function that takes no arguments and returns no value (I'm simulating the setTimeout function in JavaScript, if you must know.) case class Scheduled(time : Int, callback : => Unit) doesn't compile, saying " `val' parameters may not be call-by-name" case class Scheduled(time : Int, callback : () => Unit) compiles, but has to be invoked strangely, instead of Scheduled(40, { println("x") } ) I have to do this Scheduled(40, { () => println("x") } ) What also works is class Scheduled(time : Int, callback : Unit => Unit) but is invoked in an even-less-sensible way Scheduled(40, { x : Unit => println("x") } ) (What would a variable of type Unit be?) What I want of course is a constructor that can be invoke the way I would invoke it if it were an ordinary function: Scheduled(40, println("x") ) Give baby his bottle!

    - by Ilya Rusanen
    I have register form on every page of my website. During registration some error may occur. After cathing error, I have to return user to previous page, showing some error tips. The problem is I dont know from which page user performs registration. That's why I use res.redirect('back');. However, I cant just redirect user back, I have to show him whats wrong. Thats why I have to pass some parameter. But res.redirect('back', (reg_error:'username')}) can not be used directly 'cause res.redirect() doesn't support parameters. How can I render prevous page with some parameter? Thanks!

  • Tag filtering Query using T-SQL and Linq-to-SQL?

    - by EdenMachine
    I'm trying to figure out how to allow a user to enter in a string of tags (keywords separated by spaces) in a textbox to filter a grid of results. Here are the tables: PACKETS *PacketID Name PACKETTAGS *PacketTagID PacketID TagID Tags *TagID Name Here is the basic query without the WHERE parameters: SELECT Packets.Name, Tags.Name AS Tag, PacketTags.PacketTagID FROM Packets INNER JOIN PacketTags ON Packets.PacketID = PacketTags.PacketID INNER JOIN Tags ON PacketTags.TagID = Tags.TagID I need to filter out all the Packets that don't have tags that match any of the words BUT ALSO ONLY include the Packets that have the tags entered in the string of text (spaces separate the tags when entered into the textbox) I'm starting with the basics by figuring this out in t-SQL first but ultimately I need to be able to do this in Linq-to-SQL

  • Delphi 2010 - Why can't I declare an abstract method with a generic type parameter?

    - by James
    I am trying to do the following in Delphi 2010: TDataConverter = class abstract public function Convert<T>(const AData: T): string; virtual; abstract; end; However, I keep getting the following compiler error: E2533 Virtual, dynamic and message methods cannot have type parameters I don't quite understand the reason why I can't do this. I can do this in C# e.g. public abstract class DataConverter { public abstract string Convert<T>(T data); } Anyone know the reasoning behind this?

  • Protocols/Interfaces in Ruby

    - by fifigyuri
    While coding in Ruby I did not really miss the type-orientedness of Java or C++ so far, but for some cases I think it is useful to have them. For Python there was a project PyProtocols which defined interfaces and protocols for objects. Does a similar initiative also exist for Ruby? I would like to be able to declare the expected parameters for some methods for some objects (for the entire code I find such think useless). It the method during the execution receives an unexpected input, it tries to adapt it or if it cannot, it throws an exception. Does something similar exist for Ruby? Introducing types for a type-less language like Ruby might sound freak, but I think types are sometimes useful. Thanks for help.

  • Interesting XSL Dilemma

    - by bobber205
    I've got this issue. A template called "checkbox" that's called from while inside a table HTML element and also outside of it. To solve an issue, I've added tags to "checkbox" input control. Here's what I'd like to do to but I'm not sure if it's possible or not. When I hit my "row" (part of the custom table markup) template, I would set some variable or pass some parameter, that for each template applied afterwards, would know it was in a "row" and do something special based on this information. I know I can't add parameters to apply-templates. I may be able to add a row "mode" but I can't make changes to each template and have one copy with the mod parameter and one without. Thanks for any suggestions. I know the ideal solution would to be to make changes to the XML but I'm not sure if I can do that as this point. That's a "content" issue. :P Thanks!

  • Can I get parameter names/values procedurally from the currently executing function?

    - by Pwninstein
    I would like to do something like this: public MyFunction(int integerParameter, string stringParameter){ //Do this: LogParameters(); //Instead of this: //Log.Debug("integerParameter: " + integerParameter + // ", stringParameter: " + stringParameter); } public LogParameters(){ //Look up 1 level in the call stack (if possible), //Programmatically loop through the function's parameters/values //and log them to a file (with the function name as well). //If I can pass a MethodInfo instead of analyzing the call stack, great. } I'm not even sure what I want to do is possible, but it would be very nice to be able to automatically output parameter names/values at runtime to a file without explicitly writing the code to log them. Thanks!

  • What is the best signature for overloaded arithmetic operators in C++?

    - by JohnMcG
    I had assumed that the canonical form for operator+, assuming the existence of an overloaded operator+= member function, was like this: const T operator+(const T& lhs, const T& rhs) { return T(lhs) +=rhs; } But it was pointed out to me that this would also work: const T operator+ (T lhs, const T& rhs) { return lhs+=rhs; } In essence, this form transfers creation of the temporary from the body of the implementation to the function call. It seems a little awkward to have different types for the two parameters, but is there anything wrong with the second form? Is there a reason to prefer one over the other?

  • SSRS run SQL/DataSet conditionally

    - by MikeTWebb
    Hello.... I have an SSRS report that contains several subreports. The user has the ability to select/deselect which subreports they want to produce using several Boolean parameters. If a subreport is deselected then it is not rendered by setting the Visibility property. However, the DataSet associated with the de-selected subreport still executes causing the execution time to take longer than expected. Is there any way to tell a dataset on a subreport or Tablix not to execute based on a Parameter selection? Thanks

  • Need to interface to a C++ DLL

    - by Pedro
    Hi, I need to call a C++ API from C#. I have been able to call the API, but the char[] parameters do not seem to be marshalling correctly. Here's the C++ signature: Create2ptModel(double modelPowers[2], double modelDacs[2], int pclRange[2], double targetPowers[32], double *dacAdjustFactor, unsigned short powerRampFactors[32], BOOL bPCLDacAdjusted[32], char calibrationModel[32], char errMsg[1024]) and this is how I am trying to call it from C# [DllImport("AlgorithmsLib.dll", EntryPoint = "_Create2ptModel@36", ExactSpelling = true, CallingConvention = CallingConvention.StdCall, CharSet = CharSet.Auto)] private static extern AlgorithmStatus Create2ptModel( double[] modelPowers, double[] modelDacs, int[] pclRange, double[] targetPowers, ref double dacAdjustFactor, ushort[] powerRampFactors, bool[] bPCLDacAdjusted, /**/char[] calibrationModel, char[] errMsg/**/); Any idea of how I can marshall it correctly? Thanks in advance!

  • Windows service installed successfully but not responding after started.

    - by Ridhi
    I have a windows service written in C#, .Net framework 2.0. I installed it on three machines and it worked fine but on one machine (with .Net framework 2.0) the setup has installed the service successfully but the service is not responding after I start it. I check for this by checking whether a log file is created at a specific path insribed in the config file or not. This log file is created everytime the timer elapses the interval time. I'm unable to figure out the reason. Have checked all the parameters but unable to get any solution to this. The funny thing is that the same setup is running well on other machines. P.S.: I have admin access on all the servers I'm installing this service on.

  • if else-if making code look ugly any cleaner solution?

    - by Vishal
    I have around 20 functions (is_func1, is_fucn2, is_func3...) returning boolean I assume there is only one function which returns true and I want that! I am doing: if is_func1(param1, param2): # I pass 1 to following abc(1) # I pass 1 some_list.append(1) elif is_func2(param1, param2): # I pass 2 to following abc(2) # I pass 1 some_list.append(2) ... . . elif is_func20(param1, param2): ... Please note: param1 and param2 are different for each, abc and some_list take parameters depending on the function. The code looks big and there is repetition in calling abc and some_list, I can pull this login in a function! but is there any other cleaner solution? I can think of putting functions in a data structure and loop to call them.

  • Optimal search queries

    - by Macros
    Following on from my last question http://stackoverflow.com/questions/2788082/sql-server-query-performance, and discovering that my method of allowing optional parameters in a search query is sub optimal, does anyone have guidelines on how to approach this? For example, say I have an application table, a customer table and a contact details table, and I want to create an SP which allows searching on some, none or all of surname, homephone, mobile and app ID, I may use something like the following: select * from application a inner join customer c on a.customerid = a.id left join contact hp on (c.id = hp.customerid and hp.contacttype = 'homephone') left join contact mob on (c.id = mob.customerid and mob.contacttype = 'mobile') where (a.ID = @ID or @ID is null) and (c.Surname = @Surname or @Surname is null) and (HP.phonenumber = @Homphone or @Homephone is null) and (MOB.phonenumber = @Mobile or @Mobile is null) The schema used above isn't real, and I wouldn't be using select * in a real world scenario, it is the construction of the where clause I am interested in. Is there a better approach, either dynamic sql or an alternative which can achieve the same result, without the need for many nested conditionals. Some SPs may have 10 - 15 criteria used in this way

  • Inserting empty string into auto_increment column in MySQL 5

    - by QmunkE
    Hi, I've inherited a project which we are trying to migrate to MySQL 5 from MySQL 4.0(!) and from myISAM to InnoDB. Queries are now falling down because they are being constructed using an ADODB connection's -qstr() on all parameters, including ints. Where no value is provided I end up with: INSERT INTO tablename VALUES ('', 'stuff'...) where the first column is an auto_increment. This causes an error (fair enough since '' isn't an int). Is there a switch in MySQL to make it behave as it used to (I assume it just silently converted to 0?) Thanks.

  • lua function as argument in C

    - by Nil
    I'm going to pass a function to another function which should operate with the passed function. For example: handler(fun1("foo",2)) handler(fun2(1e-10)) The handler is something like calling the passed function many times. I'm going to bind handler, fun1, fun2 to C-functions. fun1 and fun2 are going to return some user data with a pointer to some cpp-class so that I can further recover which function was it. The problem now is that fun1 and fun2 are going to be called before passed to handler. But I don't need this, what I need is the kind of function and its parameters. However, I should be able to call fun1 and fun2 alone without handler: fun1("bar",3) fun2(1e-5) Is it possible to get the context the function is called from? While typing the question, I realized I could do following handler(fun1, "foo",2); handler(fun2, 1e-10);

  • Charts don't show up when subreport is included in group header in pentaho reporting 3.9.1-GA

    - by user2909808
    There is an issue concerning in sub-reports. I created a bar chart in report header. The sub report(inline) is placed in the Details of main report. In the sub report, the bar chart is placed in the group header. I imported the required parameters to the sub reports from the main report and also i have a sub query for the sub report.The expected output is to show an updated bar chart within each (inner) group of main report. However, the chart is only displayed in the last group occurence, although the chart area itself is allotted in every expected case. Can any one say me, what mistake i did.

  • Can MySQL automatically specify `_utf8` for inserts to UTF-8 columns?

    - by Neil
    I have a table like this, where one column is latin1, the other is UTF-8: Create Table: CREATE TABLE `names` ( `name_english` varchar(255) character NOT NULL, `name_chinese` varchar(255) character set utf8 default NULL, ) ENGINE=MyISAM DEFAULT CHARSET=latin1 When I do an insert, I have to type _utf8 before values being inserted into UTF-8 columns: insert into names (name_english = "hooey", name_chinese = _utf8 "??"); However, since MySQL should know that name_chinese is a UTF-8 column, it should be able to know to use _utf8 automatically. Is there any way to tell MySQL to use _utf8 automatically, so when I'm programatically making prepared statements, I don't have to worry about including it with the right parameters?

  • Is this basically what an IOC like NInject does?

    - by mrblah
    Normally I would do this: public class DBFactory { public UserDAO GetUserDao() { return new UserDao(); } } Where UserDao being the concrete implementation of IUserDao. So now my code will be littered with: DBFactory factory = new DBFactory(); IUserDao userDao = factory.GetUserDao(); User user = userDao.GetById(1); Now if I wanted to swap implementaitons, I would have to go to my DBFactory and change my code to call a different implementation. Now if I used NINject, I would bind the specific implementation on application startup, or via a config file. (or bind based on specific parameters etc. etc.). Is that all there is too it? Or is there more? (reason I am asking if I want to know how it will help me here: http://stackoverflow.com/questions/1930328/help-designing-a-order-manager-class)
