• jquery validation plugin doesn't seem to work ....

  - by Pandiya Chendur

  asp.net mvc's Html.BeginForm() seems to work with jquery validation plugin but the validation plugin doesn't seem to work with a form which i ve added to a page.... This works, <% using (Html.BeginForm("Login", "Registration", FormMethod.Post, new { id = "Loginform" })) {%> <fieldset> <legend>Login</legend> <p> <label for="EmailId">EmailId:</label> <%= Html.TextBox("EmailId", null, new { @class = "text_box_height_14_width_150" })%> </p> <div class="status"></div> <p> <label for="Password">Password:</label> <%= Html.Password("Password",null, new { @class = "text_box_height_14_width_150" }) %> </p> <div class="status"></div> <p> <input type="submit" value="Login" id="login" /> </p> </fieldset> <% } %> But this doesn't work, <form id="Loginform" method="post" action="Registration/Login"> <table cellpadding="0" cellspacing="0" width="100%" style="border:none;"> <tr> <td width="12%">Email Id&nbsp;:&nbsp;</td><td width="15%"> <input id="EmailId" type="text" class="text_box_height_14_width_150 name="EmailId" /></td><td width="20%" class="status"></td> <td width="12%">Password&nbsp;:&nbsp;<td width="15%"><input id="Password" type="password" class="text_box_height_14_width_150 name="Password" /></td> <td width="20%" class="status"></td> <td width="5%"><input type="submit" value="Login" id="BtnLogin" /></td> </tr> </table> </form> and my jquery function has this, $(document).ready(function() { var validator = $("#Loginform").validate({ rules: { EmailId: "required", Password: { required: true, minlength: 6 } }, messages: { EmailId: "Enter your EMail ID", Password: { required: "Please Provide a password", rangelength: jQuery.format("Enter at least {0} characters") } }, // the errorPlacement has to take the table layout into account errorPlacement: function(error, element) { error.appendTo(element.parent().next()); }, // set this class to error-labels to indicate valid fields success: function(label) { // set &nbsp; as text for IE label.html("&nbsp;").addClass("checked"); } }); }); Any suggestion... Am i missing something?

• Flex: Constant strings in metadata

  - by Daniel Engmann

  I have something like public class Controller { [Observer("fetchEmployeesEvent")] public function fetchEmployees() : void { //doSomething } } and I want something like public class Controller { public static const FETCH_EMPLOYEES_EVENT : String = "fetchEmployeesEvent"; [Observer(FETCH_EMPLOYEES_EVENT)] public function fetchEmployees() : void { //doSomething } } My problem is that only the first code snippet works. Flex seems to ignore the constant FETCH_EMPLOYEES_EVENT in the metadata-tag. My question is: Is it somehow possible to use constant strings in metadata?

• C segmentation fault before/during return statement

  - by wolfPack88

  I print the value that I'm returning right before my return statement, and tell my code to print the value that was returned right after the function call. However, I get a segmentation fault after my first print statement and before my second (also interesting to note, this always happens on the third time the function is called; never the first or the second, never fourth or later). I tried printing out all of the data that I'm working on to see if the rest of my code was doing something it maybe shouldn't, but my data up to that point looks fine. Here's the function: int findHydrogen(struct Amino* amino, int nPos, float* diff, int totRead) { struct Atom* atoms; int* bonds; int numBonds; int i; int retVal; int numAtoms; numAtoms = (*amino).numAtoms; atoms = (struct Atom *) malloc(sizeof(struct Atom) * numAtoms); atoms = (*amino).atoms; numBonds = atoms[nPos].numBonds; bonds = (int *) malloc(sizeof(int) * numBonds); bonds = atoms[nPos].bonds; for(i = 0; i < (*amino).numAtoms; i++) printf("ATOM\t\t%d %s\t0001\t%f\t%f\t%f\n", i + 1, atoms[i].type, atoms[i].x, atoms[i].y, atoms[i].z); for(i = 0; i < numBonds; i++) if(atoms[bonds[i] - totRead].type[0] == 'H') { diff[0] = atoms[bonds[i] - totRead].x - atoms[nPos].x; diff[1] = atoms[bonds[i] - totRead].y - atoms[nPos].y; diff[2] = atoms[bonds[i] - totRead].z - atoms[nPos].z; retVal = bonds[i] - totRead; bonds = (int *) malloc(sizeof(int)); free(bonds); atoms = (struct Atom *) malloc(sizeof(struct Atom)); free(atoms); printf("2 %d\n", retVal); return retVal; } } As I mentioned before, it works fine the first two times I run it, the third time it prints the correct value of retVal, then seg faults somewhere before it gets to where I called the function, which I do as: hPos = findHydrogen((&aminoAcid[i]), nPos, diff, totRead); printf("%d\n", hPos);

  I am calling three functions in my code where i want to validate some of my fields. When I tries to work with the code given below. It checks only for first value until it gets false result.

  - by Fletcher Moore

  The problem is this is hard to follow: ajaxOne(function() { // do something ajaxTwo(function() { // do something ajaxThree() }); }); I'm using a third party API to make the AJAX calls, so I need a generic solution.

• jQuery - Sorting an array?

  - by Probocop

  Hi, I'm using Ajax to get some XML, and then filling in some fields on a form with the results. There is a numerical field on the form and I would like to sort the results by this number (highest first). How would I go about doing this in jQuery? My js function code is currently: function linkCounts() { ws_url = "http://archreport.epiphanydev2.co.uk/worker.php?query=linkcounts&domain="+$('#hidden_the_domain').val(); $.ajax({ type: "GET", url: ws_url, dataType: "xml", success: function(xmlIn){ results = xmlIn.getElementsByTagName("URL"); for ( var i = 0; i < results.length; i++ ) { $("#tb_domain_linkcount_url_"+(i+1)).val($(results[i].getElementsByTagName("Page")).text()); $("#tb_domain_linkcount_num_"+(i+1)).val($(results[i].getElementsByTagName("Links")).text()); } $('#img_linkcount_worked').attr("src","/images/worked.jpg"); }, error: function(){$('#img_linkcount_worked').attr("src","/images/failed.jpg");} }); } The Links tag is the one I'm wanting to sort it on. Thanks For reference the XML that's getting returned is like the following: <?xml version="1.0" encoding="utf-8" standalone="yes"?> <Response> <ResponseCode>1</ResponseCode> <ResponseStatus>OK</ResponseStatus> <ReportId>2</ReportId> <UrlChecked /> <MaxLinks>75</MaxLinks> <PagesFound>121</PagesFound> <URLs> <URL> <Page>http://www.epiphanysolutions.co.uk/blog</Page> <Links>78</Links> </URL> <URL> <Page>http://www.epiphanysolutions.co.uk/blog/</Page> <Links>78</Links> </URL> <URL> <Page>http://www.epiphanysolutions.co.uk/blog/author/daniel-peden/</Page> <Links>78</Links> </URL> <URL> <Page>http://www.epiphanysolutions.co.uk/blog/author/daniel-peden/page/2/</Page> <Links>78</Links> </URL> </URLS> </Response>

• Returning and printing string array index in C

  - by user1781966

  I've got a function that searches through a list of names and I'm trying to get the search function to return the index of the array back to the main function and print out the starting location of the name found. Everything I've tried up to this point either crashes the program or results in strange output. Here is my search function: #include<stdio.h> #include<conio.h> #include<string.h> #define MAX_NAMELENGTH 10 #define MAX_NAMES 5 void initialize(char names[MAX_NAMES][MAX_NAMELENGTH], int Number_entrys, int i); int search(char names[MAX_NAMES][MAX_NAMELENGTH], int Number_entrys); int main() { char names[MAX_NAMES][MAX_NAMELENGTH]; int i, Number_entrys,search_result,x; printf("How many names would you like to enter to the list?\n"); scanf("%d",&Number_entrys); initialize(names,Number_entrys,i); search_result= search(names,Number_entrys); if (search_result==-1){ printf("Found no names.\n"); }else { printf("%s",search_result); } getch(); return 0; } void initialize(char names[MAX_NAMES][MAX_NAMELENGTH],int Number_entrys,int i) { if(Number_entrys>MAX_NAMES){ printf("Please choose a smaller entry\n"); }else{ for (i=0; i<Number_entrys;i++){ scanf("%s",names[i]); } } } int search(char names[MAX_NAMES][MAX_NAMELENGTH],int Number_entrys) { int x; char new_name[MAX_NAMELENGTH]; printf("Now enter a name in which you would like to search the list for\n"); scanf("%s",new_name); for(x = 0; x < Number_entrys; x++) { if ( strcmp( new_name, names[x] ) == 0 ) { return x; } } return -1; } Like I mentioned before I have tried a lot of different ways to try and fix this issue, but I cant seem to get them to work. Printing X like what I have above is just the last thing I tried, and therefor know that it doesn't work. Any suggestions on the simplest way to do this?

• compact framework windows CE using ExtEscape to control the brightness

  - by mack369

  I need to be able to control brightness of my Windows CE 5.0 device. I've found that there is an API function ExtEscape to do that ( http://msdn.microsoft.com/en-us/library/aa453063 ) but it needs a structure ContrastCmdInputParm (http://msdn.microsoft.com/en-us/library/Aa447689 ) as a parameter. Since ExtEscape is unmanaged, I cannot pass a .net structure. What is the simplest way to call this function?

• Is there a website to lookup already common code functions?

  - by pinnacler

  I'm sitting here writing a function that I'm positive has been written before, somewhere on earth. It's just too common to have not been attempted, and I'm wondering why I can't just go to a website and search for a function that I can then copy and paste into my project in 2 seconds, instead of wasting my day reinventing the wheel. Sure there are certain libraries you can use, but where do you find these libraries and when they are absent, is there a site like I'm describing?

  I use this snippet to prevent the user from accidentally navigating away from the editing page: var warning = false; window.onbeforeunload = function() { if (warning) { return ''; } } Now I want to set the variable warning to be true if any of the textarea or input type="text" has been modified, I want to use the onkeyup event such as in: document.getElementById('textarea_id').onkeyup = function() { warning = true; } But it's not working.

• PHP echo query result in Class??

  - by Jerry

  Hi all I have a question about PHP Class. I am trying to get the result from Mysql via PHP. I would like to know if the best practice is to display the result inside the Class or store the result and handle it in html. For example, display result inside the Class class Schedule { public $currentWeek; function teamQuery($currentWeek){ $this->currentWeek=$currentWeek; } function getSchedule(){ $connection = mysql_connect(DB_SERVER,DB_USER,DB_PASS); if (!$connection) { die("Database connection failed: " . mysql_error()); } $db_select = mysql_select_db(DB_NAME,$connection); if (!$db_select) { die("Database selection failed: " . mysql_error()); } $scheduleQuery=mysql_query("SELECT guest, home, time, winner, pickEnable FROM $this->currentWeek ORDER BY time", $connection); if (!$scheduleQuery){ die("database has errors: ".mysql_error()); } while($row=mysql_fetch_array($scheduleQuery, MYSQL_NUMS)){ //display the result..ex: echo $row['winner']; } mysql_close($scheduleQuery); //no returns } } Or return the query result as a variable and handle in php class Schedule { public $currentWeek; function teamQuery($currentWeek){ $this->currentWeek=$currentWeek; } function getSchedule(){ $connection = mysql_connect(DB_SERVER,DB_USER,DB_PASS); if (!$connection) { die("Database connection failed: " . mysql_error()); } $db_select = mysql_select_db(DB_NAME,$connection); if (!$db_select) { die("Database selection failed: " . mysql_error()); } $scheduleQuery=mysql_query("SELECT guest, home, time, winner, pickEnable FROM $this->currentWeek ORDER BY time", $connection); if (!$scheduleQuery){ die("database has errors: ".mysql_error()); // create an array } $ret = array(); while($row=mysql_fetch_array($scheduleQuery, MYSQL_NUMS)){ $ret[]=$row; } mysql_close($scheduleQuery); return $ret; // and handle the return value in php } } Two things here: I found that returned variable in php is a little bit complex to play with since it is two dimension array. I am not sure what the best practice is and would like to ask you experts opinions. Every time I create a new method, I have to recreate the $connection variable: see below $connection = mysql_connect(DB_SERVER,DB_USER,DB_PASS); if (!$connection) { die("Database connection failed: " . mysql_error()); } $db_select = mysql_select_db(DB_NAME,$connection); if (!$db_select) { die("Database selection failed: " . mysql_error()); } It seems like redundant to me. Can I only do it once instead of calling it anytime I need a query? I am new to php class. hope you guys can help me. thanks.

• Can Prototype or JQuery return an HTTP status code on an AJAX request

  url = "http://example.com" new Ajax.Request(url, { onComplete: function(transport) { alert(transport.status); } }); I'd like that to return a status of 200 if the site is working, or 500 if it is not working, etc.. But that code is returning 0 all the time. Ultimately, I want to have a setinterval function that regularly pings a website for uptime status.

• PHP problem with getimagesize()

  I'm using the getimagesize() function in PHP and it keeps returning an error: getimagesize(image.php?name=username&pic=picture) [function.getimagesize]: failed to open stream: No such file or directory I'm not doing anything strange with it. The only problem I can imagine is that the path URL is another PHP script that returns a page with an image header, and there is an ampersand in that URL. Here is my code: $location = "image.php?name=username&pic=picture"; $size = getimagesize($location);
