  • C# compile error for simple Annual Salary Calculator

    - by Mike Vignapiano
    I am new to C# and trying to create my 1st app. I have 3 errors. The first two say that txtSalary and Salary do not exist. The 3rd says that it cannot convert method group 'ToString' to non-delegate type 'string'. and asks if I intend to invoke the method. Here is what I have: protected void Button1_Click(object sender, EventArgs e) { int salary, AnnualHours, Rate; string txtAnnualHours, txtSalary, txtRate; salary = AnnualHours * Rate; txtsalary = int.Parse(Salary); txtAnnualHours = salary.ToString; MessageBox.Show(salary); } According to my book, when you enter numerics in AnnualHours and Rate textbox, when click Button1, these values are converted from string to integers, then multiplied for salary. Then numeric answer converted to string and displayed in messagebox named txtSalary. Please show me what I got wrong because according to the book, I am not missing anything.

  • How to kill a thread immediately from another thread in java?

    - by Sara
    Hi, is there anyway to kill a thread or interrupt it immediately. Like in one of my thread, i call a method which takes time to execute (2-4 seconds). This method is in a while(boolean flag) block, so i can interrupt it from the main thread. But the problem is, if i interrupt it; it will wait till the executing loop is finished and then on next conditional check, it will stop execution. I want it to stop right then. Is there anyway to do this?

  • C#: Convert array to use in params with additional parameters

    - by user1805759
    I have a method that takes params. Inside the method another variable shall be added to the output: private void ParamsTest(params object[] objs) { var foo = "hello"; // Invalid: Interpretes objs as single array parameter: Console.WriteLine("{0}, {1}, {2}", foo, objs); } When I call ParamsTest("Hi", "Ho"); I would like to see the output. hello Hi Ho What do I need to do? I can copy foo and objs into a new array and pass that array to WriteLine but is there a more elegant way to force objs to behave as params again? Kind of objs.ToParams()?

  • Securing input of private / protected methods?

    - by ts
    Hello, normally, all sane developers are trying to secure input of all public methods (casting to proper types, validating, sanitizing etc.) My question is: are you in your code validating also parameters passed to protected / private methods? In my opinion it is not necessary, if you securize properly parameters of public methods and return values from outside (other classes, db, user input etc...). But I am constantly facing frameworks and apps (ie. prestashop to name one) where validation is often repeated in method call, in method body and once again for securize returned value - which, I think, is creating performace overhead and is also a sign of bad design.

  • SQL Server 2005 to 2008 Bak file help please!

    - by Brandon
    I have a SQl Server 2005 database backup that I want to transfer to SQL Server 2008 on my server. I spent 3 days transferring the .bak file from my own machine to my server. I then tried to restore the bak file and I got an error. I then read online a completely different method for adding a SQL server 2005 Database to SQL server 2008 which was the detach and attach method which means I need to detach the database in SQL Server 2005 and then transfer the MDF file from it via ftp to my server and then attach it in SQL Server 2008. Well I already used a lot of bandwidth transferring the .bak file to my server. is there a way to convert my .bak file which is already on my server to an MDF file and attach it in SQL server 2008?

  • Badword filter in PHP?

    - by morpheous
    I am writing a badword filter in PHP. I have a list of badwords in an array and the method cleanse_text() is written like this: public static function cleanse_text($originalstring){ if (!self::$is_sorted) self::doSort(); return str_ireplace(self::$badwords, '****', $originalstring); } This works trivially, for exact matches, but I wanted to also censor words that have been disguised like 'ab*d' where 'abcd' is a bad word. This is proving to be a bit more difficult. Here are my questions: Is a badword filter worth bothering with (it is a site for professionals so a certain minimum decorum is required - I would have thought) Is it worth the hustle of trying to capture obvious work arounds like 'f*ck' - or should I not attempt to filter those out. Is there a better way of writing the cleanse_text() method above?

  • WCF: How to find out when a session is ending?

    - by TomTom
    I have a WCF application that is using sessions. Is there any central event to get thrown when a session ends? How can I find out when a session is ending WITHOUT (!) calling a method (network disconnect, client crashing - so no "logout" method call)? The server is hosted as: [ServiceBehavior( InstanceContextMode = InstanceContextMode.PerSession, ConcurrencyMode = ConcurrencyMode.Reentrant, UseSynchronizationContext = false, IncludeExceptionDetailInFaults = true )] Basically because it is using a callback interface. Now, I basically need to decoubple the instance created from the backend store when the session terminates ;) Any ideas?

  • Listing C/C++ functions (Code analysis in Unix)

    - by Jond
    Whether we're maintaining unfamiliar code or checking out the implementation details of an Apache module it can help if we can quickly traverse the code and build up an overview of what we're looking at. Grep serves most of my daily needs but there are some cases where it just wont do. Here's a common example of how it can help. To find the definition of a PHP function I'm interested in I can type this at the command line: grep -r "function myfunc" . This could be adapted very quickly to C or C++ if we know the return type, but things become more complicated if, say, I want to list every method that my class provides: grep "function " ./src/mine.class.php Since there's no single keyword that denotes a function or method in C++ and because it's generally more complex syntax, I think I'd need some kind of static code analysis tool, smart use of the C Preprocessor or blind faith the coder followed strict code guidelines (# of whitespace, position of curlies etc) to get these sorts of results. What would you recommend? p.s. be nice, this is my first post ;-) :p

  • Exposing console apps to the web with Ruby

    - by Aaron
    I'm looking to expose an interactive command line program via JSON or another RPC style service using Ruby. I've found a couple tricks to do this, but im missing something when redirecting the output and input. One method at least on linux is to redirect the stdin and stdout to a file then read and write to that file asynchronously with file reads and writes. Another method ive been trying after googling around was to use open4. Here is the code I wrote so far, but its getting stuck after reading a few lines from standard output. require "open4" include Open4 status = popen4("./srcds_run -console -game tf +map ctf_2fort -maxplayers 6") do |pid, stdin, stdout, stderr| puts "PID #{pid}" lines="" while (line=stdout.gets) lines+=line puts line end while (line=stderr.gets) lines+=line puts line end end Any help on this or some insight would be appreciated!

  • Json Object to a Multidimensional C# Array?

    - by Nick Brooks
    Is there a way to convert a Json Object to a Multidimensional C# Array? I know it might be impractical but I can't be bothered to write classes and then deserialize the strings into them. List<string> ohyeah = (List<string>)JsonConvert.DeserializeObject(g.CommToken); That returns an Invalid Cast exception! Example: {"method":"getCommunicationToken","header":{"uuid":"9B39AAB0-49A6-AC7A-BA74-DE9DA66C62B7","clientRevision":"20100323.02","session":"c0d3e8b5d661f74c68ad72af17aeb5a1","client":"gslite"},"parameters":{"secretKey":"d9b687fa10c927f102cde9c085f9377f"}} I need to get something like that : j["method"]; //This will equal to getCommunicationToken j["header"]["uuid"]; //This will equal to 9B39AAB0-49A6-AC7A-BA74-DE9DA66C62B7 I literally need to parse the json object into an array.

  • How much effort does it take to spoof an Ip Address in a call to a webservice?

    - by Rory Becker
    I don't want to know how... Just how complicated.... I'm thinking of securing a webservice or 2 based on the incoming client ipaddress of the caller. Is this in any way secure? Surely if the IPaddress was being spoofed then the result would have to be sent back to the address that was being spoofed and therefore not reach the spoofer? Update: Ok so from what I can tell.... I should create a Gettoken() method which checks the IPaddress and passes out a cryptographically significant token with a timeout to any valid IP address. This is then required by any other method before any kind of side effect is allowed. Since an Attacker can't (likely) get the token without having a valid IP, he will be unable to validly call any of my "dangerous" webmethods ?

  • How to add a slot to my main window in Qt builder?

    - by George Edison
    I am using Qt Builder to create a simple window. I used the menu editor to add a menu. Now, I figured out how to connect one of the menu items to the close() method of the main window. My problem is how to add a slot to the main window. Here is what I have: private slots: void OnAbout(); However, I can't get this method to show up in the 'Signals and Slots Editor'. How can I get it to show up?

  • Creating an XmlNode/XmlElement in C# without an XmlDocument?

    - by Michael Stum
    I have a simple class that essentially just holds some values. I have overridden the ToString() method to return a nice string representation. Now, I want to create a ToXml() method, that will return something like this: <Song> <Artist>Bla</Artist> <Title>Foo</Title> </Song> Of course, I could just use a StringBuilder here, but I would like to return an XmlNode or XmlElement, to be used with XmlDocument.AppendChild. I do not seem to be able to create an XmlElement other than calling XmlDocument.CreateElement, so I wonder if I have just overlooked anything, or if I really either have to pass in either a XmlDocument or ref XmlElement to work with, or have the function return a String that contains the XML I want?

  • Java, How to Instance HttpCookie from a String, any convenient ways?

    - by user435657
    Hi all, I have got a cookie string from HTTP response header like the following line: name=value; path=/; domain=.g.cn; expire=... I can parse the above line to key-value pairs, and, also it's easy to set the name and value to HttpCookie instance as this pair comes the first. But how to set the other pairs since I don't know which set-method corresponds to the name of the next name-value pair. Traverse all possible keys a cookie may contian and call the matched set-method, like below snippet? if (key.equalsIgnoreCase("path")) cookie.setPath(value); else if (key.equalsIgnoreCase("domain")) cookie.setDomain(value); That's foolish, any convenient ways? Thanks in advance.

  • Getting value of LSB from Hex (C code)

    - by Rjff
    Hi - first post here :) I've got a code like this in C: unsigned char const data[ ] = {0x0a, 0x1d, 0xf0, 0x07}; I need to extract it such that the final value is: 0xa1df7 I have only been able to extract and get it working if the hex values that have at least 1 zero: unsigned char const data[ ] = {0x0a, 0xd0, 0xf0, 0x07}; using the code below: for(int i = 0; i < SIZE; ++i) { tmp = data[i]; if ( (data[i] <= 0x0F) && (((data[i] & 0x0F) == 0) || (data[i] & 0xF0) == 0)) // one of the hex is zero { tmp = ((tmp << 4) >> 4) << N[i]; std::cout << "foo: " << std::hex << tmp << ":" << std::endl; } else if ((data[i] >= 0x0F) && (((data[i] & 0x0F) == 0) || (data[i] & 0xF0) == 0) ) { tmp = (tmp >> 4) << N[i]; std::cout << "bar: " << std::hex << tmp << ":" << std::endl; } else { std::cout << "result: " << std::hex << result << ":" << std::endl; std::cout << "tmp << 8: " << std::hex << (tmp << 8)<< ":" << std::endl; result = result | (tmp << 8); std::cout << "result |= (tmp << 8): " << std::hex << result << ":" << std::endl; } result |= tmp; std::cout << "boo: " << std::hex << result << ":" << std::endl; } It seems the last else {...} block is troublesome for me. Any ideas? Thanks!

  • Passing arguments between classes - use public properties or pass a properties class as argument?

    - by devoured elysium
    So let's assume I have a class named ABC that will have a list of Point objects. I need to make some drawing logic with them. Each one of those Point objects will have a Draw() method that will be called by the ABC class. The Draw() method code will need info from ABC class. I can only see two ways to make them have this info: Having Abc class make public some properties that would allow draw() to make its decisions. Having Abc class pass to draw() a class full of properties. The properties in both cases would be the same, my question is what is preferred in this case. Maybe the second approach is more flexible? Maybe not? I don't see here a clear winner, but that sure has more to do with my inexperience than any other thing. If there are other good approaches, feel free to share them. Here are both cases: class Abc1 { public property a; public property b; public property c; ... public property z; public void method1(); ... public void methodn(); } and here is approach 2: class Abc2 { //here we make take down all properties public void method1(); ... public void methodn(); } class Abc2MethodArgs { //and we put them here. this class will be passed as argument to //Point's draw() method! public property a; public property b; public property c; ... public property z; } Also, if there are any "formal" names for these two approaches, I'd like to know them so I can better choose the tags/thread name, so it's more useful for searching purposes. That or feel free to edit them.

  • C# arraylist can't compare objects after they are loaded from disk

    - by Zka
    To make it easy, lets say I have an arraylist allBooks containing class "books" and an arraylist someBooks containing some but not all of the "books". Using contains() method worked fine when I wanted to see if a book from one arraylist was also contained in another. The problem was that this isn't working anymore when I save both of the Arraylists to a .bin file and load them back once the program restarts. Doing the same test as before, the contains() returns false even if the compared objects are the same (have the same info inside). I solved it by overloading the equals method and it works fine, but I want to know why did this happen?

  • Update database using restful ASP.NET MVC 1.0

    - by Mike
    We are building an MVC 1.0 application right now and using Linq - SQL for our DAL. Following the restful approach we have multiple action events depending on if you are updating or loading or what not. The two that I'm concerned with at this point are the edit and update action methods. Here is the signatures. public ActionResult Update(int customerId, int Id, AggregateModel viewModel) public ActionResult Edit(int customerId, int Id, AggregateModel viewModel) So the idea is that in the Edit method we load up our viewModel and pass it to the view. The user makes changes to the model and then posts back to the Update method. The first thing I could think of to do would be to get the viewModel from the database again, copy the changes in one by one from the posted back model and then submit it back. This would work but does seem clunky to me. What is the best way to insert those changes into the database at this point?

  • How to solve this Java type safety warning? (Struts2)

    - by Nicolas Raoul
    Map session = ActionContext.getContext().getSession(); session.put("user", user); This code generates a warning: Type safety: The method put(Object, Object) belongs to the raw type Map. References to generic type Map should be parameterized. Map<String, Serializable> session = (Map<String, Serializable>)ActionContext.getContext().getSession(); session.put("user", user); This code generates a warning: Type safety: Unchecked cast from Map to Map. The getSession method belongs to Struts2 so I can't modify it. I would like to avoid using @SuppressWarnings because other warnings can be useful. I guess all Struts2 users in the world faced the same problem... is there an elegant solution?

  • Multiple key map in c++

    - by Morgan
    Hi, I'm wondering if any of you know of a c++ associative map container type which I can perform multiple key lookups on. The map needs to have constant time lookups but I don't care if it's ordered or unordered. It just needs to be fast. For example, I want to store a bunch of std::vector objects in a map with an integer and a void* as the lookup keys. Both the int and the void* must match for my vector to be retrieved. Does anything like this exist already? Or am I going to have to roll my own. If so, any suggestions? I've been trying to store a boost::unordered_map inside another boost::unordered_map, but I have not had any success with this method yet. Maybe I will continue Pershing this method if there is no simpler way. Thanks!

  • Does a Category applied to NSString also apply to NSCFString via the "toll-free bridge"?

    - by half_brick
    We're integrating a library into an iPhone app which appears to use the google toolbox for iPhone internally. The google toolbox adds a method gtm_stringBySanitizingAndEscapingForXML to NSString. The problem is, whenever we attempt to make a call to this library we get [NSCFString gtm_stringBySanitizingAndEscapingForXML]: unrecognized selector sent to instance 0x272478 So it appears the library is calling that method on a NSCFString, to which the category does not apply. So... is it the case that the category will not apply across the toll-free bridge to CoreFoundation classes? If that's the case then we at least know why it's blowing up. Figuring out how to fix it is a different matter.
