  • C# OOP File Structure?

    - by Soo
    Hey SO, I just started programming with objects recently and am trying to learn good habits early on. The way I plan to structure my application is to have two files: 1: Program.cs - This file will contain the main logic for the application 2: Class.cs - This file will contain all of the class definitions Pretty simple. What I'm wondering if I should have any more files for ... well, you tell me. Any help would be appreciated.

    - by dominic
    Hi I am having a problem debugging an issue on a website. Everything works locally, the local and server databases are the same The strange thing about the error is that it points to my local dev machine in the error stack. Is that crazy or what, The files are published and being hosted on a server machine and the error is pointing to a line of code on my local dev box. I feel like I am losing the plot. Can someone pls help be clear the air here because this is very weird Error in '/' Application. Index was out of range. Must be non-negative and less than the size of the collection.

  • Are there other search options for heroku

    - by Jonathan
    I am about to launch a beta site, and heroku looks like a great option. The only think that is getting me down is that the only search option is $20/mth for the Websolr add-on. I am sure that Websolr is great, but at this very early point in this project, I rather not light up that expense. Are there any free search options to couple with heroku's Blossom (free) plan. I feel like such a cheapskate!

  • Java: JPQL select statement

    - by bguiz
    select x from X x where x.a.id = :a_id -- Always 0 objects selected Why does the above JPQL statement not work, but the one below work? select a from A a where a.id = :a_id -- a_obj select x from X x where x.a = :a_obj -- Always correct number of objects selected Neither query throws an exception during execution, but a different number of results are obtained. Thanks

  • iphone uiwebview inital white view

    - by BahaiResearch.com
    My app's main view has a uiwebview. It is white for a split second before it has time to render the HTML the app generates. Is there a way to make the uiwebview black, or another color, before it renders? The flash of white isn't part of my plan for a smooth visual transition. Objective-C or MonoTouch answers are fine, I am bi-lingual.

  • Web Services Primer for a WinForms Developer?

    - by Unicorns
    I've been writing client/server applications with Winforms for about six years now, but I have yet to venture into the web space (neither ASP.NET nor web services). Given the direction that the job market has been heading for some time and the fact that I have a basic curiosity, I'd like to get involved with writing web services, but I don't know where to start. I've read about various options (XML/SOAP vs. JSON, REST vs...well, actually I don't know what it's called, etc.), but I'm not sure what sort of criteria are in play when making the determination to use one or the other. Obviously, I'd like to leverage the tools that I have (Visual Studio, the .NET framework, etc.) without hamstringing myself into only targeting a particular audience (i.e. writing the service in such a way as to make it difficult to consume from a Windows Mobile/Android/iPhone client, for example). For the record, my plan--for now--is to use WCF for my web service development, but I'm open to using another .NET approach if that's advisable. I realize that this question is pretty open-ended so it may get closed, but here are some things I'm wondering: What are some things to consider when choosing the type of web service (REST, etc.) I intend to write? Is it possible (and, if so, feasible) to move from one approach to another? Can web services be written in an event-driven way? As I said I'm a Winforms developer, so I'm used to objects raising events for me to react to. For instance, if I have two clients connected to my service, is there a way for me to "push" information to one of them as a result of an action by the other? If this is possible, is this advisable or am I just not thinking about it correctly? What authentication mechanisms seem to work best for public-facing services? What about if I plan to have different types of OS'es and clients connecting to the service? Is there a generally accepted platform-agnostic approach? In the line of authentication, is this something that I should be doing myself (authenticating an managing sessions, etc.) or is this something should be handled at the framework level and I just define exactly how it should work? If that's the case, how do I tell who the requester has authenticated themselves as? I started writing an authentication mechanism (simple username/password combinations stored in the database and a corresponding session table with a GUID key) within my service and just requiring that key to be passed with every operation (other than logging in, of course), but I want to make sure that I'm not reinventing the wheel here. However, I also don't want to clutter up the server with a bunch of machine user accounts just to use Basic authentication. I'm also under the impression that Digest (and of course Windows) authentication requires a machine (or AD) user account.

  • method with two parameters which both need to be double dispatched

    - by mixm
    lets say i have a method which has two parameters. i have been implementing them as: if(aObj instance of Marble) { if(bObj instance of Bomb) { this.resolve((Marble)aObj,(Bomb)bObj); } } as you can see its not a very pretty solution. i plan to implement using double dispatching, but with two parameters which both need double dispatching, im afraid im a bit stumped. any ideas please. im implementing in java btw.

  • RIA: Manipulate DOM

    - by stephanos
    I want to display a website embedded in my own site and modify the DOM (e.g. change a button's color/size), similar to what Firebug is capable of. I'm aware of the security issues that arise - my plan is to use this approach to do live website usability testing (A/B style). I'm not limited to any specific RIA framework (yet would prefer Flex) - but it has to work without installing anything (so no AIR). Cheers :-)

  • how to find index of a row in sql server?

    - by NoviceToDotNet
    How can i fetch column names from a tale on index basis, like i want to make a tables whose column name should be the name of last column fields of a result set of a query, but those result sets last columns value may be different at different execution time, so i want to know how can i fetch those index value of that last column to make a temp table with column name of those last columns value of a result set. Is there any way/function in sql server to dynamically form that?

    - by Chris Klepeis
    I'd like to detemine the amount of time it takes for my ASP.Net program to generate certain sql queries using linq.... note - I want the query generation time, not the query execution time. Is this possible, or even feasable (if its usually fast)? My website has some heavy traffic and I want to cover all of my bases.

  • How to install VS.NET 2010 without Team Explorer

    - by LexL
    Since we don't use and don't plan to use TFS, it would be nice to not install Team Explorer VS.NET addon and not see any references to it. However this is no TFS option in customized install. Is there some way to install plain-vanilla VS.NET 2010 without it? Or maybe there is some kind of TFS uninstaller?

  • Mobile Java Applet?

    - by luvieere
    Is there any mobile platform that allows me to run Java Applets? In absence of browser integration, at least Java SE capabilities. I've heard of a mobile device capable of running Windows XP - that would probably include support for Java SE and applets; does any one have any hands-on experience with such a device? How well does it perform in terms of Java programs execution?

  • Ruby is already using the class name of my model

    - by Octopus Inc
    I'm making a forum application with various levels of authorization, one of which is a Monitor. I am doing this by extending my User class, and I plan on fine tuning this with "-ship" classes (e.g. administratorship, authorship, moderatorship, etc.). Apparently the Monitor class is part of ruby mixin. How do I keep my resource name without the collisions?

  • I need help on my C++ assignment using Microsoft Visual C++

    - by krayzwytie
    Ok, so I don't want you to do my homework for me, but I'm a little lost with this final assignment and need all the help I can get. Learning about programming is tough enough, but doing it online is next to impossible for me... Now, to get to the program, I am going to paste what I have so far. This includes mostly //comments and what I have written so far. If you can help me figure out where all the errors are and how to complete the assignment, I will really appreciate it. Like I said, I don't want you to do my homework for me (it's my final), but any constructive criticism is welcome. This is my final assignment for this class and it is due tomorrow (Sunday before midnight, Arizona time). This is the assignment: Examine the following situation: Your company, Datamax, Inc., is in the process of automating its payroll systems. Your manager has asked you to create a program that calculates overtime pay for all employees. Your program must take into account the employee’s salary, total hours worked, and hours worked more than 40 in a week, and then provide an output that is useful and easily understood by company management. Compile your program utilizing the following background information and the code outline in Appendix D (included in the code section). Submit your project as an attachment including the code and the output. Company Background: Three employees: Mark, John, and Mary The end user needs to be prompted for three specific pieces of input—name, hours worked, and hourly wage. Calculate overtime if input is greater than 40 hours per week. Provide six test plans to verify the logic within the program. Plan 1 must display the proper information for employee #1 with overtime pay. Plan 2 must display the proper information for employee #1 with no overtime pay. Plans 3-6 are duplicates of plan 1 and 2 but for the other employees. Program Requirements: Define a base class to use for the entire program. The class holds the function calls and the variables related to the overtime pay calculations. Define one object per employee. Note there will be three employees. Your program must take the objects created and implement calculations based on total salaries, total hours, and the total number of overtime hours. See the Employee Summary Data section of the sample output. Logic Steps to Complete Your Program: Define your base class. Define your objects from your base class. Prompt for user input, updating your object classes for all three users. Implement your overtime pay calculations. Display overtime or regular time pay calculations. See the sample output below. Implement object calculations by summarizing your employee objects and display the summary information in the example below. And this is the code: // Final_Project.cpp : Defines the entry point for the console application. // #include "stdafx.h" #include <iostream> #include <string> #include <iomanip> using namespace std; // //CLASS DECLARATION SECTION // class CEmployee { public: void ImplementCalculations(string EmployeeName, double hours, double wage); void DisplayEmployInformation(void); void Addsomethingup (CEmployee, CEmployee, CEmployee); string EmployeeName ; int hours ; int overtime_hours ; int iTotal_hours ; int iTotal_OvertimeHours ; float wage ; float basepay ; float overtime_pay ; float overtime_extra ; float iTotal_salaries ; float iIndividualSalary ; }; int main() { system("cls"); cout << "Welcome to the Employee Pay Center"; /* Use this section to define your objects. You will have one object per employee. You have only three employees. The format is your class name and your object name. */ std::cout << "Please enter Employee's Name: "; std::cin >> EmployeeName; std::cout << "Please enter Total Hours for (EmployeeName): "; std::cin >> hours; std::cout << "Please enter Base Pay for(EmployeeName): "; std::cin >> basepay; /* Here you will prompt for the first employee’s information.

Prompt the employee name, hours worked, and the hourly wage. For each piece of information, you will update the appropriate class member defined above. Enter the employee name = Enter the hours worked = Enter his or her hourly wage = */ /* Here you will implement a function call to implement the employ calcuations for each object defined above. You will do this for each of the three employees or objects. The format for this step is the following: [(object name.function name(objectname.name, objectname.hours, objectname.wage)] ; */ /* This section you will send all three objects to a function that will add up the the following information: - Total Employee Salaries - Total Employee Hours - Total Overtime Hours The format for this function is the following: - Define a new object. - Implement function call [objectname.functionname(object name 1, object name 2, object name 3)] /* } //End of Main Function void CEmployee::ImplementCalculations (string EmployeeName, double hours, double wage){ //Initialize overtime variables overtime_hours=0; overtime_pay=0; overtime_extra=0; if (hours > 40) { /* This section is for the basic calculations for calculating overtime pay. - base pay = 40 hours times the hourly wage - overtime hours = hours worked – 40 - overtime pay = hourly wage * 1.5 - overtime extra pay over 40 = overtime hours * overtime pay - salary = overtime money over 40 hours + your base pay */ /* Implement function call to output the employee information.
