  • asp:login form does not submit when you hit enter

    - by Ben Liyanage
    I am having an issues while using the <asp:login> tag. When a user clicks the "login" button, the form will process correctly. However, when the user hits the enter key, the form self submits and does not process the login, whether it was correct information or not. I am using a combination of MasterPages, and Umbraco. My aspx code looks like this: <%@ Master Language="C#" MasterPageFile="/masterpages/AccountCenter.master" CodeFile="~/masterpages/Login.master.cs" Inherits="LoginPage" AutoEventWireup="true" %> <asp:Content ContentPlaceHolderID="RunwayMasterContentPlaceHolder" runat="server"> <div class="loginBox"> <div class="AspNet-Login-TitlePanel">Account Center Login</div> <asp:label id="output" runat="server"></asp:label> <asp:GridView runat="server" id="GridResults" AutoGenerateColumns="true"></asp:GridView> <asp:Login destinationpageurl="~/dashboard.aspx" ID="Login1" OnLoggedIn="onLogin" runat="server" TitleText="" FailureText="The login/password combination you provided is invalid." DisplayRememberMe="false"></asp:Login> </div> </asp:Content> In the actual rendered page, I see this javascript on the form: <form method="post" action="/dashboard.aspx?" onsubmit="javascript:return WebForm_OnSubmit();" id="aspnetForm"> That javascript function is defined as: <script type="text/javascript"> //<![CDATA[ function WebForm_OnSubmit() { if (typeof(ValidatorOnSubmit) == "function" && ValidatorOnSubmit() == false) return false; return true; } //]]> </script> The javascript is always evaluating to True when it runs.

  • C: Proper syntax for allocating memory using pointers to pointers.

    - by ~kero-05h
    This is my first time posting here, hopefully I will not make a fool of myself. I am trying to use a function to allocate memory to a pointer, copy text to the buffer, and then change a character. I keep getting a segfault and have tried looking up the answer, my syntax is probably wrong, I could use some enlightenment. /* My objective is to pass a buffer to my Copy function, allocate room, and copy text to it. Then I want to modify the text and print it.*/ #include <stdio.h> #include <stdlib.h> #include <string.h> int Copy(char **Buffer, char *Text); int main() { char *Text = malloc(sizeof(char) * 100); char *Buffer; strncpy(Text, "1234567890\n", 100); Copy(&Buffer, Text); } int Copy(char **Buffer, char *Text) { int count; count = strlen(Text)+1; *Buffer = malloc(sizeof(char) * count); strncpy(*Buffer, Text, 5); *Buffer[2] = 'A'; /* This results in a segfault. "*Buffer[1] = 'A';" results in no differece in the output. */ printf("%s\n", *Buffer); }

  • Changing character encoding in MySQL, PHP scripts, HTML

    - by Sandman
    So, I have built on this system for quite some time, and it is currently outputting Latin1 (ISO-8859-1) to the web browser, and this is the components: MySQL - all data is stored with the Latin1 character set PHP - All PHP text files are stored on disk with Latin1 encoding HTML - The output has the http-equiv="content-type" content="text/html; charset=iso-8859-1" meta tag So, I'm trying to understand how the encoding of the different parts come into play in my workflow. If I open a PHP script and change its encoding within the text editor to UTF-8 and save it back to disk and reload the web browser, the text is all messed up - unless the text comes from the DB. If I change the encoding of the DB to UTF-8 and keep the PHP files in latin1 I have to use utf8_decode() for the data to display correctly. And if I change the HTML code the browser will read it incorrectly. So yeah, I realise that if I want to "upgrade" to UTF8, I have to update all three parts of this setup for it to work correctly, but since it's a huge system with some 180k lines of PHP code and millions of posts in a lot of databases/tables, I don't want to start something like this without understanding everything correctly. What haven't I thought about? What could mess this up beyond fixing? What are the procedures for changing the encoding of an entire MySQL installation and what's the easiest way to change the encoding of hundreds or thousands of PHP files on disk? The META tag is luckily added dynamically, so I'll change that in one place only :) Let me hear about your experiences with this.

  • Database Functional Programming in Clojure

    - by Ralph
    "It is tempting, if the only tool you have is a hammer, to treat everything as if it were a nail." - Abraham Maslow I need to write a tool to dump a large hierarchical (SQL) database to XML. The hierarchy consists of a Person table with subsidiary Address, Phone, etc. tables. I have to dump thousands of rows, so I would like to do so incrementally and not keep the whole XML file in memory. I would like to isolate non-pure function code to a small portion of the application. I am thinking that this might be a good opportunity to explore FP and concurrency in Clojure. I can also show the benefits of immutable data and multi-core utilization to my skeptical co-workers. I'm not sure how the overall architecture of the application should be. I am thinking that I can use an impure function to retrieve the database rows and return a lazy sequence that can then be processed by a pure function that returns an XML fragment. For each Person row, I can create a Future and have several processed in parallel (the output order does not matter). As each Person is processed, the task will retrieve the appropriate rows from the Address, Phone, etc. tables and generate the nested XML. I can use a a generic function to process most of the tables, relying on database meta-data to get the column information, with special functions for the few tables that need custom processing. These functions could be listed in a map(table name -> function). Am I going about this in the right way? I can easily fall back to doing it in OO using Java, but that would be no fun. BTW, are there any good books on FP patterns or architecture? I have several good books on Clojure, Scala, and F#, but although each covers the language well, none look at the "big picture" of function programming design.

  • How do I get column names to print in this C# program?

    - by Kevin
    I've cobbled together a C# program that takes a .csv file and writes it to a datatable. Using this program, I can loop through each row of the data table and print out the information contained in the row. The console output looks like this: --- Row --- Item: 1 Item: 545 Item: 507 Item: 484 Item: 501 I'd like to print the column name beside each value, as well, so that it looks like this: --- Row --- Item: 1 Hour Item: 545 Day1 KW Item: 507 Day2 KW Item: 484 Day3 KW Item: 501 Day4 KW Can someone look at my code and tell me what I can add so that the column names will print? I am very new to C#, so please forgive me if I've overlooked something. Here is my code: // Write load_forecast data to datatable. DataTable loadDT = new DataTable(); StreamReader sr = new StreamReader(@"c:\load_forecast.csv"); string[] headers = sr.ReadLine().Split(','); foreach (string header in headers) { loadDT.Columns.Add(header); // I've added the column headers here. } while (sr.Peek() > 0) { DataRow loadDR = loadDT.NewRow(); loadDR.ItemArray = sr.ReadLine().Split(','); loadDT.Rows.Add(loadDR); } foreach (DataRow row in loadDT.Rows) { Console.WriteLine("--- Row ---"); foreach (var item in row.ItemArray) { Console.Write("Item:"); Console.WriteLine(item); // Can I add something here to also print the column names? } }

  • Globalize/Localize Excel Reports Using Spreadsheet

    - by mga911
    My company has new customers in Brazil and we realized that our excel reports are not working when our Brazilian customers tried to open the reports in their Brazilian versions of excel. For excel output we use spreadsheet gear in our vb.net web application. Our excel worksheets are fairly simple. Mostly outputted text/numbers/dates, a couple of formulas (sum, if) and formatting on the currency and dates. I've tried several methods to get my excel reports to work: First I left the excel workbook in the "en-US" culture and tried simply chaging the number format for Brazil to: _-[$R$-416] * #.##0,00_-;-[$R$-416] * #.##0,00_-;_-[$R$-416] * "-"??_-;_-@_- And this formatted the regular cells but the formulas still failed to show a value. Instead they showed a 0 value. Next I tried changing the workbook to the "pt-BR" culture and that also forced me to translate the formula names (Sum - Soma, If - Se) but they still wouldn't should a value and instead showed a #Name/#Nome error. Interestingly enough the formulas would work if I edited the cell and hit enter. The formula wouldn't change but it would some how fix that cell. I need to be able to out excel reports that can format dates/currencies and apply simple formulas (IF, Sum) for other excel cultures. Anyone have any advice?

  • Javascript Rich Display WYSIWYG Component/Methodology

    - by Laramie
    quick back story-- I am working on ASP.Net based template editor that lets authors create text templates using Javascript inserted placeholder tags that will be filled in with dynamic text when the templates are used to display the final results. For example the author might create a template like The word [%12#add] was generated dynamically. The application would eventually replace the tag with a dynamic word down the road (though it's not specifically relevant to this post) The word foo was generated dynmamically. Depending on the circumstances, the template may be created in a text input, textarea or a modified version of the Ajax Control Toolkit HTML Editor. There might be 40 or more of these editable elements on the page, so using lots of stripped down or modified HTML editors would probably bog the page down too much. The problem is that the tags such as [%12#add] are displayed inline with the user text and the result is confusing and aesthetically gross. The goal is parse the contens of the source element and when a tags such as [%12#add] are encountered, display something prettier and less cryptic to the user such as a stylable element or image wherever tags such as [%12#add] occur. The application still needs the template text with the tags on postback. So the user might see The word tag placeholder was generated dynamically. but the original template would still be the value of the text input box The word [%12#add] was generated dynamically. It seems HTML editors like the ACT version and FckEditor accomplish this by rendering their output in an IFrame, but rather than kill myself trying to roll a lighter specialized version myself, I thought I'd ask if anyone knows of an existing free component or approach that has already tackled this. With good reason, I don't think S.O. allows HTML formatting, but the bold "tag placeholder" above would ideally be something like tag placeholder.

  • why is OOP hard for me?

    - by netrox
    I have trouble writing OOP in PHP... I understand the concept but I never create classes for my projects... mainly because it's often a small project and nothing complex. But when I read OOP, it seems more difficult to code than writing simple procedural statements. It also seems to take a lot of room as well with so many empty abstract classes and that can be easily lost in the land of objects... it's becoming like a junkyard to me. Also, I noticed that virtually all instructions on how to use OOP use "car" or "cat" or "dog" analogies. Hello... we're not dealing with animals or cars... we're dealing with windows or consoles. You can talk about analogies to death and I will never learn. What I want is see a code that's written to show how objects are created - not, "aCow-moo!" For example, I want to see a browser window object displaying say... three inputs. I want to see an "object" created to output a window with three inputs then I want to see how overriding works, like change the window object to display only two inputs instead of three inputs. I think that would make learning more easy, wouldn't it? Any recommended tutorials of that nature instead of quacks, moos, and woofs.

  • Attention JavaScript gurus: Need a hand with setInterval()

    - by alex
    I am trying to make a non interactive display for a real estate shop window. It's been a while since I've played with setInterval(). The first time my script steps through, it is fine. But when it tries to get the next property via getNextProperty(), it starts to go haywire. If you have Firebug, or an equivalent output of console.log(), you'll see it is calling things it shouldn't! Now there is a fair bit of JavaScript, so I'll feel better linking to it than posting it all. Store Display Offending JavaScript It is worth mentioning all my DOM/AJAX is done with jQuery. I've tried as best to make sure clearInterval() is working, and it seems to not run any code below it. The setInterval() is used to preload the next image, and then display it in the gallery. When the interval detects we are at the last image ((nextListItem.length === 0)), it is meant to clear that interval and start over with a new property. It has been driving me nuts for a while now, so anyone able to help me? It is probably something really obvious! Many thanks!

  • Querying a database using Cocoa.

    - by S1syphus
    Hello everybody. Before I start a disclaimer, I should add a little disclaimer, that I am relatively new to Cocoa development and C in general. However I do have a copy of 'Cocoa Programming for Mac OS X 3rd edition' by Aaron Hillegass, which I am working through and using as a base, if anybody has a copy I am using the 'AmaZone' example on page 346 as a template and base. I trying to develop a small client app that takes a search string then displays results from a database accordingly. The database will contain a: list of files, their location, description & creation date, so for the moment the field number and types will remain the same. After looking around on SO, I saw something like: NSURL *myURL = [NSURL URLWithString:@"http://www.myserver.com/results.php"]; NSArray *sqlResults = [[NSArray alloc] initWithContentsOfURL:myURL]; I've worked with php before, so my current thinking after seeing this is create a php script on the server that queries the database, and creates an XML output. And with the XML response, just parse it. Would this be ok? as is there any major pitfalls anybody can see, that I can't. I know there are some database bundles, I've had a look at BaseTen for Postgres, but being relatively new to this, didn't want to get in over my head. Or if anybody else has any other suggestions and ideas, they would be greatly appreciated.

My Form <form id="LoginForm" runat="server"> <asp:ScriptManager ID="LoginScriptMgr" runat="server"></asp:ScriptManager> <asp:UpdatePanel ID="LoginPanel" runat="server"> <ContentTemplate> <asp:Label ID="lblLoginHeader" Text="Login" runat="server"></asp:Label> <asp:TextBox ID="txtUserName" runat="server"></asp:TextBox> <asp:TextBox ID="txtPassword" runat="server" TextMode="Password"></asp:TextBox> <asp:Button ID="btnLogin" Text="Login" runat="server" OnClick="Login" /> <asp:Label ID="lblLoginStatus" runat="server" /> </ContentTemplate> </asp:UpdatePanel> </form> C# Code protected void Login(object sender, EventArgs e) { lblLoginStatus.Text = "Login Successful"; } Web.config <httpModules> <add name="TimeModule" type="MyWebPortal.App_Code.TimeModule,App_Code"/> </httpModules> HTTP Module public class TimeModule : IHttpModule { private HttpApplication oApps = null; public void Dispose() { } public void Init(System.Web.HttpApplication context) { oApps = context; context.PreSendRequestContent += new EventHandler (context_PreSendRequestContent); } void context_PreSendRequestContent(object sender, EventArgs e) { string message = "&lt;!-- This page is being processed at " + System.DateTime.Now.ToString() + " -->"; oApps.Context.Response.Output.Write(message); } } When i remove the TimeModule from Web.config my ajax works. If add the TimeModule then the label doesn't show the message "Login Successful". Removing the ajax panel and with httpmodule available the label shows the message. So, how ajax panel was related to httpmodules?

  • C#/.NET library for source code formatting, like the one used by Stack Overflow?

    - by Lasse V. Karlsen
    I am writing a command line tool to convert Markdown text to html output, which seems easy enough. However, I am wondering how to get nice syntax coloring for embedded code blocks, like the one used by Stack Overflow. Does anyone know either: What library StackOverflow is using or if there's a library out there that I can easily reuse? Basically it would need to have some of the same "intelligence" found in the one that Stack Overflow uses, by basically doing a best-attempt at figuring out the language in use to pick the right keywords. Basically, what I want is for my own program to handle a block like the following: if (a == 0) return true; if (a == 1) return false; // fall-back Markdown Sharp, the library I'm using, by default outputs the above as a simple pre/code html block, with no syntax coloring. I'd like the same type of handling as the formatting on Stack Overflow does, the above contains blue "return" keywords for example. Or, hmm, after checking the source of this Stack Overflow page after adding the code example, I notice that it too is formatted like a simple pre/code block. Is it pure javascript-magic at works here, so perhaps there's no such library? If there's no library that will automagically determine a possible language by the keywords used, is there one that would work if I explicitly told it the language? Since this is "my" markdown-commandline-tool, I can easily add syntax if I need to.

  • C#: Wrong answer when finding "cool" numbers.

    - by user300484
    Hello you all! In my application, a "cool" number is a number that is both a square and a cube, like for example: 64 = 8^2 and 64 = 4^3. My application is supposed to find the number of "cool numbers" between a range given by the user. I wrote my code and the application runs fine, but it is giving me the wrong answer. Can you help me here please? for example: IMPUT 1 100 OUTPUT 1 using System; using System.Collections.Generic; using System.Linq; using System.Text; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { double a = Convert.ToDouble(Console.ReadLine()); // first number in the range double b = Convert.ToDouble(Console.ReadLine()); // second number in the range long x = 0; for (double i = a; i <= b; i++) { double cube = 1.0 / 3.0; double cuad = 1.0 / 2.0; double crt = Math.Pow(i, cube); // cube root double sqrt = Math.Pow(i, cuad); // square root if ((crt * 10) % 10 == 0 || (sqrt * 10) % 10 == 0) // condition to determine if it is a cool number. x++; } Console.WriteLine(x); Console.ReadLine(); } } }

  • Write a program which works out which is the lowest priced computer in an ArrayList of computer obje

    - by Eoin
    Hello everybody! I am trying to study some java and cannot get my head around this question! Any help would be really appreciated and would help me in further studies! Thank you so much in advance! Eoin from Dublin, Ireland. ArrayList of Objects Write a program which works out which is the lowest priced computer in an ArrayList of computer objects. You should have two classes, one called ComputerTest, and the other called Computer. In the ComputerTest class you should: Have a main method which declares an ArrayList of type Computer called computerList, each element of which represents a computer. Initialise the first three entries of the ArrayList Call a static method which prints out the lowest price computer, called lowestPrice The parameter of this method is (i) an ArrayList of type Computer i.e. ArrayList data Sample output: The lowest priced computer is the Cheapo400 at 399 euro. The Computer class should have: Private instance variables: manufacturer, model, price and quality. Quality is a rating from 1 to 10. public get and set methods to retrieve and set/change the value of the four instance variables a default constructor a constructor that takes four parameters

  • PHP: Best solution for links breaking in a mod_rewrite app

    - by psil
    I'm using mod rewrite to redirect all requests targeting non-existent files/directories to index.php?url=* This is surely the most common thing you do with mod_rewrite yet I have a problem: Naturally, if the page url is "mydomain.com/blog/view/1", the browser will look for images, stylesheets and relative links in the "virtual" directory "mydomain.com/blog/view/". Problem 1: Is using the base tag the best solution? I see that none of the PHP frameworks out there use the base tag, though. I'm currently having a regex replace all the relative links to point to the right path before output. Is that "okay"? Problem 2: It is possible that the server doesn't support mod_rewrite. However, all public files like images, stylesheets and the requests collector index.php are located in the directory /myapp/public. Normally mod_rewrite points all request to /public so it seems as if public was actually the root directory too all users. However if there is no mod_rewrite, I then have to point the users to /public from the root directory with a header() call. That means, however that all links are broken again because suddenly all images, etc. have to be called via /public/myimage.jpg Additional info: When there is no mod_rewrite the above request would look like this: mydomain.com/public/index.php/blog/view/1 What would be the best solutions for both problems?

  • How to implement generic callbacks in C++

    - by Kylotan
    Forgive my ignorance in asking this basic question but I've become so used to using Python where this sort of thing is trivial that I've completely forgotten how I would attempt this in C++. I want to be able to pass a callback to a function that performs a slow process in the background, and have it called later when the process is complete. This callback could be a free function, a static function, or a member function. I'd also like to be able to inject some arbitrary arguments in there for context. (ie. Implementing a very poor man's coroutine, in a way.) On top of that, this function will always take a std::string, which is the output of the process. I don't mind if the position of this argument in the final callback parameter list is fixed. I get the feeling that the answer will involve boost::bind and boost::function but I can't work out the precise invocations that would be necessary in order to create arbitrary callables (while currying them to just take a single string), store them in the background process, and invoke the callable correctly with the string parameter.

  • How to handle large dataset with JPA (or at least with Hibernate)?

    - by Roman
    I need to make my web-app work with really huge datasets. At the moment I get either OutOfMemoryException or output which is being generated 1-2 minutes. Let's put it simple and suppose that we have 2 tables in DB: Worker and WorkLog with about 1000 rows in the first one and 10 000 000 rows in the second one. Latter table has several fields including 'workerId' and 'hoursWorked' fields among others. What we need is: count total hours worked by each user; list of work periods for each user. The most straightforward approach (IMO) for each task in plain SQL is: 1) select Worker.name, sum(hoursWorked) from Worker, WorkLog where Worker.id = WorkLog.workerId group by Worker.name; //results of this query should be transformed to Multimap<Worker, Long> 2) select Worker.name, WorkLog.start, WorkLog.hoursWorked from Worker, WorkLog where Worker.id = WorkLog.workerId; //results of this query should be transformed to Multimap<Worker, Period> //if it was JDBC then it would be vitally //to set resultSet.setFetchSize (someSmallNumber), ~100 So, I have two questions: how to implement each of my approaches with JPA (or at least with Hibernate); how would you handle this problem (with JPA or Hibernate of course)?
