  • T-SQL: How to make a positive value turn into the equivalent negative value (e.g "10.00" to "-10.00"

    - by RPM1984
    Ok so i have a DECIMAL field called "Score". (e.g 10.00) Now, in my SP, i want to increment/decrement the value of this field in update transactions. So i might want to do this: SET @NewScore = @CurrentScore + @Points Where @Points is the value im going to increment/decrement. Now lets say @Points = 10.00. In a certain scenario, i want 10.00 to become -10.00 So the statement would be translated to: SET @NewScore = @CurrentScore + -10.00 How can i do that? I know its a strange question, but basically i want that statement to be dynamic, in that i dont want to have a different statement for incrementing/decrementing the value. I just want something like this: SET @Points = 10.00 IF @ActivityBeingPerformedIsFoo BEGIN -- SET @Points to be equivalent negative value, (e.g -10.00) END SET @NewScore = @CurrentScore + @Points

  • Problem in doing Add Web Reference (http://.../service.asmx)

    - by flopdix
    I am trying to Add a Web Reference to http//.../service.asmx file in my project. First it gives me an error: "... Unable to download following files from: http://.../service.asmx?wsdl Do you want to skip these files and continue ..." When i click 'Yes', the proxy gets created with .disco and other reference files, but does not adds .wsdl file. Other option i tried, i used http//.../service.asmx?wsdl to add web reference. In this case, i dont get any error, but the proxy gets added with .wsdl and reference files, but it does not adds .disco file. Can someone help me on why this is happening? I thought, adding web reference to .asmx should add everything under the proxy.

  • jQuery getting these functions to work together

    - by brett
    I'm new to jQuery and have tried looking around for an answer on how to do this. I have 2 functions and I would like both to work together. The one function is submitHandler and its used to hide a form and at the same time add a class to a hidden element to unhide it - ie a thank you for submitting h1. The other function is to grab the input data and display it onsubmit in the form. So the problem is that I can get that one to work but then the other doesnt. Ie on form submit I can see the data input but not the h1 Thank you message. Here are the functions: SubmitHandler: submitHandler: function() { $("#content").empty(); $("#content").append( "<p>If you want to be kept in the loop...</p>" + "<p>Or you can contact...</p>" ); $('h1.success_').removeClass('success_').addClass('success_form'); $('#contactform').hide(); }, onsubmit="return inputdata()" function inputdata(){ var usr = document.getElementById('contactname').value; var eml = document.getElementById('email').value; var msg = document.getElementById('message').value; document.getElementById('out').innerHTML = usr + " " + eml + msg; document.getElementById('out').style.display = "block"; return true; }, The form uses PHP and jQuery - I dont know about AJAX but after some reading even less sure. Please help me out I dont know what I'm doing and at the moment I am learning but its a long road for me still. Thank you The form: <form method="post" action="<?php echo $_SERVER['PHP_SELF']; ?>" id="contactform" onsubmit="return inputdata()"> <div class="_required"><p class="label_left">Name*</p><input type="text" size="50" name="contactname" id="contactname" value="" class="required" /></div><br/><br/> <div class="_required"><p class="label_left">E-mail address*</p><input type="text" size="50" name="email" id="email" value="" class="required email" /></div><br/><br/> <p class="label_left">Message</p><textarea rows="5" cols="50" name="message" id="message" class="required"></textarea><br/> <input type="submit" value="submit" name="submit" id="submit" /> </form> The PHP bit: <?php $subject = "Website Contact Form Enquiry"; //If the form is submitted if(isset($_POST['submit'])) { //Check to make sure that the name field is not empty if(trim($_POST['contactname']) == '') { $hasError = true; } else { $name = trim($_POST['contactname']); } //Check to make sure sure that a valid email address is submitted if(trim($_POST['email']) == '') { $hasError = true; } else if (!eregi("^[A-Z0-9._%-]+@[A-Z0-9._%-]+\.[A-Z]{2,4}$", trim($_POST['email']))) { $hasError = true; } else { $email = trim($_POST['email']); } //Check to make sure comments were entered if(trim($_POST['message']) == '') { $hasError = true; } else { if(function_exists('stripslashes')) { $comments = stripslashes(trim($_POST['message'])); } else { $comments = trim($_POST['message']); } } //If there is no error, send the email if(!isset($hasError)) { $emailTo = '[email protected]'; //Put your own email address here $body = "Name: $name \n\nEmail: $email \n\nComments:\n $comments"; $headers = 'From: My Site <'.$emailTo.'>' . "\r\n" . 'Reply-To: ' . $email; mail($emailTo, $subject, $body, $headers); $emailSent = true; } } ? The Jquery Validate bit: $(document).ready(function(){ $('#contactform').validate({ showErrors: function(errorMap, errorList) { //restore the normal look $('#contactform div.xrequired').removeClass('xrequired').addClass('_required'); //stop if everything is ok if (errorList.length == 0) return; //Iterate over the errors for(var i = 0;i < errorList.length; i++) $(errorList[i].element).parent().removeClass('_required').addClass('xrequired'); }, Here is the full jQuery bit: $(document).ready(function(){ $('#contactform').validate({ showErrors: function(errorMap, errorList) { //restore the normal look $('#contactform div.xrequired').removeClass('xrequired').addClass('_required'); //stop if everything is ok if (errorList.length == 0) return; //Iterate over the errors for(var i = 0;i < errorList.length; i++) $(errorList[i].element).parent().removeClass('_required').addClass('xrequired'); }, submitHandler: function() { $('h1.success_').removeClass('success_').addClass('success_form'); $("#content").empty(); $("#content").append('#sadhu'); $('#contactform').hide(); }, }); }); Latest edit - Looks like this: $(document).ready(function(){ $('#contactform').validate({ showErrors: function(errorMap, errorList) { //restore the normal look $('#contactform div.xrequired').removeClass('xrequired').addClass('_required'); //stop if everything is ok if (errorList.length == 0) return; //Iterate over the errors for(var i = 0;i < errorList.length; i++) $(errorList[i].element).parent().removeClass('_required').addClass('xrequired'); }, function submitHandler() { $('h1.success_').removeClass('success_').addClass('success_form'); $("#content").empty(); $("#content").append('#sadhu'); $('#contactform').hide(); }, function inputdata() { var usr = document.getElementById('contactname').value; var eml = document.getElementById('email').value; var msg = document.getElementById('message').value; document.getElementById('out').innerHTML = usr + " " + eml + msg; document.getElementById('out').style.display = "block"; }, $(document).ready(function(){ $('#contactForm').submit(function() { inputdata(); submitHandler(); }); }); });

  • Different programming languages possibilities

    - by b-gen-jack-o-neill
    Hello. This should be very simple question. There are many programming languages out there, compiled into machine code or managed code. I first started with ASM back in high school. Assembler is very nice, since you know what exactly CPU does. Next, (as you can see from my other questions here) I decided to learn C and C++. I choosed C becouse from what I read it is the language with output most close to assembler-written programs. But, what I want to know is, can any other Windows programming language out there call win32 API? To be exact, like C has its special header and functions for win32 api interactions, is this assumed to be some important part of programming language? Or are there any languages that have no support for calling win32 API, or just use console to IO and some functions for basic file IO? Becouse, for Windows programming with graphic output, it is essential to have acess to win32 API. I know this question might seem silly, but still please, help me, I ask for study porposes. Thanks.

    Hi all I have a series of asp:ImageButtons and one asp:Image(Big). Clicking on each ImageButton should change the ImageUrl of asp:Image to a new ImageUrl.

This makes my application run very slow and also pass too many server requests. Any ideas ????How to design one powerful Javascript function. By the way when the user clicks on ImageButton...the ImageUrl that has to be set to asp:Image(Big) is same as that of ImageButton. This might help a bit. Thanks in advance

  • PHP static objects giving a fatal error

    - by Webbo
    I have the following PHP code; <?php component_customer_init(); component_customer_go(); function component_customer_init() { $customer = Customer::getInstance(); $customer->set(1); } function component_customer_go() { $customer = Customer::getInstance(); $customer->get(); } class Customer { public $id; static $class = false; static function getInstance() { if(self::$class == false) { self::$class = new Customer; } else { return self::$class; } } public function set($id) { $this->id = $id; } public function get() { print $this->id; } } ?> I get the following error; Fatal error: Call to a member function set() on a non-object in ....../classes/customer.php on line 9 Can anyone tell me why I get this error? I know this code might look strange, but it's based on a component system that I'm writing for a CMS. The aim is to be able to replace HTML tags in the template e.g.; <!-- component:customer-login --> with; <?php component_customer_login(); ?> I also need to call pre-render methods of the "Customer" class to validate forms before output is made etc. If anyone can think of a better way, please let me know but in the first instance, I'd like to know why I get the "Fatal error" mentioned above. Cheers

  • mod rewrite to remove facebook query string

    - by user905752
    I can't get my query string to work..please help... I have the following url: http://betatest.bracknell-forest.gov.uk/help?fb_action_ids=372043216205703&fb_action_types=og.likes&fb_source=aggregation&fb_aggregation_id=288381481237582 (sorry but the page will be unavailable as it is a test internal domain link) I want the following url: http://betatest.bracknell-forest.gov.uk/help I get a browser message saying 'The system cannot find the file specified.' I know it is because I already have a mod rewrite to remove the .htm from the page name to return clean urls but I don't know what I need to do to accept a clean url and return the page. Here is the mod rewrite code I have: RewriteRule ^/([\w]+)$ /$1.htm [I,L] #Any bare URL will get rewritten to a URL with .htm appended RedirectRule ^/(.+)\.(htm)$ http://betatest.bracknell-forest.gov.uk/$1 [R=301] RewriteCond %{QUERY_STRING} ^fb_action_ids=(.)$ #if the query string contains fb_action_ids RewriteCond %{QUERY_STRING} !="" #if there is a query string RewriteRule ^(.*) $1? [R=301,L] I think it is because I am using R=301 twice but do not know what I need to use as an alternative. If I append .htm from help?fb_action_ids.... to help.htm?fb_action_ids.... this returns the required page fine but I need to return the page name for the non appended url. Many thanks for any help in advance.

  • Visual Studio 2008 closes unexpectedly

    - by Jose
    I don't know if I can really get an answer to this question, but it really irks me and I would like to know if someone has an idea how to arrive to an answer. I have a pretty large solution in VS 2008 that maybe every week/every other week whenever I click properties to get to the project properties the IDE closes without warning. After that happens it will close EVERY time I try and view the properties. At that point I try and delete the .suo file, I resize the IDE, I close the tabs within the project, I restore default VS Settings(when I'm desperate). Eventually 20-30 minutes later I can actually view the properties. I haven't figured out exactly what fixes it, seems to be different every time. Once it's "fixed" I can't break it again so I can figure out what "fixed" it. This seems to be project specific, because I can view properties of other projects while this project is misbehaving. I guess my first question is, does VS log reasons for closing unexpectedly? Can I find out what the offending reason behind this is? The main frustration is I don't know that cause, nor the cure. Any ideas?

  • Is there a definitive reference document for Ruby syntax?

    - by JSW
    I'm searching for a definitive document on Ruby syntax. I know about the definitive documents for the core API and standard library, but what about the syntax itself? For instance, such a document should cover: reserved words, string literals syntax, naming rules for variables/classes/modules, all the conditional statements and their permutations, and so forth. I know there are many books and tutorials, yes, but every one of them is essentially a tutorial, each one having a range of different depth and focus. They will all, by necessity of brevity and narrative flow, omit certain details of the language that the author deems insignificant. For instance, did you know that you can use a case statement without an initial case value, and it will then execute the first true when clause? Any given Ruby book or tutorial may or may not cover that particular lesser-known functionality of the case syntax. It's not discussed in the section in "Programming Ruby" about case statements. But that is just one small example. So far the best documentation I've found is the rubyspec project, which appears to be an attempt to write a complete test suite for the language. That's not bad, but it's a bit hard to use from a practical standpoint as a developer working on my own projects. Am I just missing something or is there really no definitive readable document defining the whole of Ruby syntax?

  • Regular Expression .net flavor

    Dont ask how this works but currently it does ("^\|(.?)\|*$")....kinda. This removes all extra pipes...part one....I have searched all over no anwser yet. I am using VB2011 beta...asp web form......vb coding though! I want to capture special character pipe (|) which is used to seperate words...i.e. car|truck|van|cycle problem is users lead with, trail with, use multiple, and use spaces before and after...i.e. |||car||truck | van || cycle. another example: george bush|micheal jordon|bill gates|steve jobs <-- this would be correct but when I do remove space it takes correct space out. so I want to get rid of whitespace leading, trailing, any space before | and space after | and only allow one pipe (|)....in between alphanumeric of course.

  • mongoDB many to many with one query?

    - by PowderKeg
    in mysql i use JOIN and one query is no problem. what about mongo? imagine categories and products. products may have more categories. categories may have more product. (many to many structure) and administrator may edit categories in administration (categories must be separated) its possible write product with categories names in one query? i used this structure categories { name:"categoryName", product_id:["4b5783300334000000000aa9","5783300334000000000aa943","6c6793300334001000000006"] } products { name:"productName", category_id:["4b5783300334000000000bb9","5783300334000000000bb943","6c6793300334001000000116"] } now i can simply get all product categories, and product in some category and categories alone for editation. but if i want write product with categories names i need two queries - one to get product categories id and second to get categories names from categories by that ids. is this the right way? or this structure is unsuitable? i would like to have only one query but i dont know if its possible.

  • Need help with a LINQ ArgumentOutOfRangeException in C#

    - by Christopher Klein
    Hi there, Hoping this is a nice softball of a question for a friday but I have the following line of code: //System.ArgumentOutOfRangeException generated if there is no matching data currentAnswers = new CurrentAnswersCollection().Where("PARTICIPANT_ID", 10000).Load()[0]; CurrentAnswersCollection is a strongly-typed collection populated by a view going back to my database. The problem of course is that if there is not a corresponding PARTICIPANT_ID = 10000 I get the error message. Is there a better way to write this so that I wouldn't get the error message at all? I just dont know enough about LINQ syntax to know if I can test for the existance first? thanks.

    I would like to display an intelligent 404 page with some application data. Currently, there is a 'dumb' jsp, so I just forward to the view and I am done with it. But now I guess I really need to forward to an action so that I can set some more data to display on the error.jsp. How do I do it through configuration via struts-config? I need congifuration because I do not want to touch any individual files that might be forwarding to the existing view. I tried doing the fol, but I get an error and I dont see anything in the log. So currently, <forward name="ErrorView" path="/Error404.jsp" type="org.apache.struts.action.ActionForward"> </forward> What I want: <forward name="ErrorView" path="/errorAction.do" type="org.apache.struts.action.ActionForward"> </forward>

  • How to find image width and height dynamically and specify height, width attibutes if over certain d

    - by Wbdvlpr
    Hi, I display some data on my website and one of the data feed elements is an image. [title] => Product title [description] => some description [image] => www.some-domain.com/product-image/p12345.jpg I then display this image using <img alt="product" src="<?=$data['image']?>" /> Most of the images are 80x80, 120x100 or other less than 150 in width, which perfectly fit in the website template, but some of them are quite large such as 800x600 which distort the layout. I want a control on these types. I tried to set WIDTH="150", but as the width vary they dont look good. I was thinking If I could set a fixed width to images, say, larger than 250px then I can live with it for now. Any ideas how to achieve this? Thanks

  • Rails original release source code

    - by user547057
    Hi, I've been looking to read some ruby code(specifically Rails) but I don't want to start with the current version of Rails since it has a lot of stuff I don't need and even more stuff that I wouldn't probably understand. I want to read only the core of Rails and supposedly the early versions were small and kind of easy to wrap one's head around(even for a neophyte like me). I have tried searching for the original release of rails, but have not been able to find it. The github repo consists of thousands of commits and I don't want to wade through those. What I want is to know whether there is any place I can get a zip or tar file with the original rails source or even the other early versions. Pointers to links will be very much appreciated. Thanks. p.s I'm new to ruby programming but not programming in general(I know a little python and scheme) and I understand blocks, lambdas and OO stuff, so I think I can tackle the rails source code. If anyone knows of other ruby projects that make for good code reading, i'd love to know of those too.

  • Firefox proxy dilemma

    - by Mike L.
    Any idea why when using system proxy settings in firefox, it can not accept a proxy such as: user:[email protected]:port ??? IE will allow and connect to a proxy in this format. Not only does firefox not work, but it does not prompt for the password, nor attempt to make a connection to the proxy. Basically get a "proxy server not found" error. Anybody know a way around this? I am working on a proxy switching program for IE & Firefox, and I would like to use system-wide proxy settings. If I just store the server:port combination, firefox prompts for the password, as well as IE. Then they can be cached and it will not ask again. Maybe my only option is to programmatically cache the user/pass? Anybody know a way to do this? I am pretty sure IE stores them at HTTP basic authentication passwords and I can add them with AddCredential. After saving a password for a proxy in firefox, it shows up in saved passwords in a format like "moz-proxy://server:port" anybody know how to programmatically add a saved password to firefox? Thanks
