  • XNA/C# Game Settings (Menu?)

    - by PCAddict
    It's my first time trying to make anything really interesting in C# and I was trying to make a simple form or game screen where the user could define a custom resolution/screen ratio etc. or to automatically detect the max screen size/ratio and output? its my first game, so I was wondering if it was possible or if there would be any major issues with such, rather than just setting it to 1366x768 (the resolution of all of my computers). Thanks in advance for any assistance.

  • Client side validation of multiple radio buttons groups

    This is my code: <html> <head> <title>scoreboard</title> <script> function calculate() { var sum=0; var total=0; for (var i=0; i < document.questions.group1.length; i++){ if (document.questions.group1[i].checked){ sum = parseInt(document.questions.group1[i].value) total = parseInt(total + sum);}} for (var i=0; i < document.questions.group2.length; i++){ if (document.questions.group2[i].checked){ sum = parseInt(document.questions.group2[i].value) total = parseInt(total + sum);}} for (var i=0; i < document.questions.group3.length; i++){ if (document.questions.group3[i].checked){ sum = parseInt(document.questions.group3[i].value) total = parseInt(total + sum);}} alert(total) } </script> </head> <body> <form name="questions"> A:<br> answer a1: <input type="radio" name="group1" value="0"> answer a2: <input type="radio" name="group1" value="1"> answer a3: <input type="radio" name="group1" value="2"> answer a4: <input type="radio" name="group1" value="3"><br> B:<br> answer b1: <input type="radio" name="group2" value="0"> answer b2: <input type="radio" name="group2" value="1"> answer b3: <input type="radio" name="group2" value="2"> answer b4: <input type="radio" name="group2" value="3"><br> C:<br> answer c1: <input type="radio" name="group3" value="0"> answer c2: <input type="radio" name="group3" value="1"> answer c3: <input type="radio" name="group3" value="2"> answer c4: <input type="radio" name="group3" value="3"><br><br> <input type="button" value="total" onclick="calculate()"> </form> </body> </html> How can I replace 'group[x]' in my code by a variable, so the three for-loops are replaced by one (because in reality there are a lot more questions and answers) ?

  • Understanding WebRequest

    - by Nai
    I found this snippet of code here that allows you to log into a website and get the response from the logged in page. However, I'm having trouble understanding all the part of the code. I've tried my best to fill in whatever I understand so far. Hope you guys can fill in the blanks for me. Thanks string nick = "mrbean"; string password = "12345"; //this is the query data that is getting posted by the website. //the query parameters 'nick' and 'password' must match the //name of the form you're trying to log into. you can find the input names //by using firebug and inspecting the text field string postData = "nick=" + nick + "&password=" + password; // this puts the postData in a byte Array with a specific encoding //Why must the data be in a byte array? byte[] data = Encoding.ASCII.GetBytes(postData); // this basically creates the login page of the site you want to log into WebRequest request = WebRequest.Create("http://www.mrbeanandme.com/login/"); // im guessing these parameters need to be set but i dont why? request.Method = "POST"; request.ContentType = "application/x-www-form-urlencoded"; request.ContentLength = data.Length; // this opens a stream for writing the post variables. // im not sure what a stream class does. need to do some reading into this. Stream stream = request.GetRequestStream(); // you write the postData to the website and then close the connection? stream.Write(data, 0, data.Length); stream.Close(); // this receives the response after the log in WebResponse response = request.GetResponse(); stream = response.GetResponseStream(); // i guess you need a stream reader to read a stream? StreamReader sr = new StreamReader(stream); // this outputs the code to console and terminates the program Console.WriteLine(sr.ReadToEnd()); Console.ReadLine();

  • LINQ-to-SQL - C# - OnValidate()

    - by Mark Comix
    Hello, I have a system with 3 layers and I am using LINQ-to-SQL to persist. I want to validate if the description field of my object is empty. I am using partial classes and the method OnValidate(). If the field is empty, it throws an exception. Is this correct? What do I do after the exception to not close the form, letting the user continue working? Thank you very much Sorry for my poor english

  • HTML File upload field style

    - by Steven1350
    I am trying to create a file upload field that has a little bit of style to it, but I seem to be having problems finding examples of this. I know part of the reason is that the field itself varies from browser to browser. Any ideas how to do this? Or is there a way to do this without using a file element of a form that can be styled?

  • Radio button inside anchor element is reset after jQuery click handler

    - by GrievousAngel
    I have a situation where an element, of type radio, is contained in an element. The anchor element has a href but I want to override that behaviour by adding a jQuery 'click' handler to the element. The click handler makes the radio button inside it the selected one within the group. This all works when the anchor is clicked, however, when the radio button is clicked it appears that jQuery resets the selected radio to the previously selected one! Here is a the simplified page that duplicates the issue: <html> <head> <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.4.4/jquery.min.js"></script> <script type="text/javascript"> $(document).ready(function() { $("#a1").click(function(event) { anchorClicked("a1"); return false; }); $("#a2").click(function(event) { anchorClicked("a2"); return false; }); }); function anchorClicked(anchorId) { $('#' + anchorId + ' input:radio').attr("checked", true); alert("Look at what is selected and what happens after the event when this dialog is closed!"); } </script> </head> <body> <form> <ul> <li id="li1"> <a id="a1" href="javascript:alert('default functionality')"> <input value="1" name="rb" type="radio" id="rb1"> <span>Details 1</span> </a> </li> <li id="li2"> <a id="a2" href="javascript:alert('default functionality')"> <input value="2" name="rb" type="radio" id="rb2"> <span>Details 2</span> </a> </li> </ul> </form> </body> Does anyone have any idea how I can prevent jQuery for resetting the radio button?

    How do i deal with dependent combo boxes in the views with the form helper. For example: Country Select Box (Choosing a country shall filter out the states of the selected country) States Select Box This should happen with the help of Javascript / Jquery etc. I came across an example for the same with Cake's core AJAX helper but it would be very nice if someone can help with a Javascript example.

  • How to find the ocean using Google Maps API

    - by geejay
    I am trying to figure out where the ocean is in an arbitrary Google Maps view. I actually have the lat lon (a range of points, when joined together form the coastline) of the coastline. But how do I tell which side of this line is the coastline? One possible solution would be to find the latlon of the nearest service or town or business or something, and then the ocean is obviously on the other side (given a small enough enclosing polygon). Is there a better way?

  • Why do some questions get closed for no reason? [closed]

    - by IVlad
    Recently there was a question asking about generating all subsets of a set using a stack and a queue, which was closed (and now deleted it seems) as not a real question for no good reason, since it didn't fit into any of these conditions: It's difficult to tell what is being asked here. No, it was clear what was being asked. This question is ambiguous, vague, incomplete, or rhetorical and cannot be reasonably answered in its current form. Not ambiguous, not vague, not incomplete, definitely not rhetorical and could easily be answered if one knew the solution. Now, the exact same thing has happened with this question: http://stackoverflow.com/questions/2791982/a-shortest-path-problem-with-superheroes-and-intergalactic-journeys/2793746#2793746 I am interested in hearing a logical argument for why that question is either ambiguous, vague, incomplete, rhetorical or cannot reasonably be answered in its current form. It seems that (the same bunch of) people like to close questions that they think are homework questions, especially when they think people want to be served the solution on a platter, which is also not the case: Any suggestions or ideas of how this problem might be solved would be most welcomed. Most of the time the people asking these questions are very reasonable and appreciate even the most vague idea, yet their question is closed. Let's go further and assume that it IS a homework problem. So what? When I registered here I didn't see any rule that said not to post homework problems, nor do I see such a rule now. What is wrong with posting homework problems that makes people hunt them down with a passion to close them without even reading the entire question body? This site is full of questions asked by people who get paid to know the things they are asking, yet their questions are considered fine. How is solving someone's homework problem worse? In some places (like where I live), computer science is a mandatory high school subject, and not everyone is interested in it. How is helping at least those people worse than doing someone's JOB? Not answering homework questions is fine and it's everyone's choice, but I consider closing them to be an act of power abuse, selfishness, and an insult to the fellow community members who are also interested in a solution or want feedback on their proposed solution. So my questions are: - Why do questions like the above get closed for reasons that do not apply? Why do you close them? Why don't you? - Why doesn't a vote to reopen a question reopen it automatically? Needing 5 votes for a reopen takes too long, and it's not fair because one reopen vote basically cancels out a close vote, making it 4 close votes (or 5 to 1, which is the same as only 4 people wanting to close the question), which isn't enough to close the question. I think a question should only be closed when CloseVotes - ReopenVotes >= 5. I'm hoping this will stay up, but I realize it probably won't. In either case, I think this is worth saying and discussing, since it IS community-related.

  • Checkbox 'off' value

    - by Richard JP Le Guen
    Does anyone have a no JavaScript way to make HTML checkbox still submit a value? As in if you check it the form submission will include a value A but if it is uncheck it still contains a value B? While I figure there isn't any way, I'm working on a site which needs to still be function when JS is off, and this would be ideal.
