  • PHP mySQL Error

    - by happyCoding25
    Hello, Im new to php so I decided to follow this tutorial for a simple login screen. I got the code setup but when I try login I get this error: Warning: mysql_num_rows(): supplied argument is not a valid MySQL result resource in (a long file path to the script) on line 27 The code I got from the tutorial is: <?php ob_start(); $host="thehost"; // Host name $username="myusername"; // Mysql username $password="mypass"; // Mysql password $db_name="test"; // Database name $tbl_name="members"; // Table name // Connect to server and select databse. mysql_connect("$host", "$username", "$password")or die("cannot connect"); mysql_select_db("$db_name")or die("cannot select DB"); // Define $myusername and $mypassword $myusername=$_POST['myusername']; $mypassword=$_POST['mypassword']; // To protect MySQL injection (more detail about MySQL injection) $myusername = stripslashes($myusername); $mypassword = stripslashes($mypassword); $myusername = mysql_real_escape_string($myusername); $mypassword = mysql_real_escape_string($mypassword); $sql="SELECT * FROM $tbl_name WHERE username='$myusername' and password='$mypassword'"; $result=mysql_query($sql); // Mysql_num_row is counting table row $count=mysql_num_rows($result); // If result matched $myusername and $mypassword, table row must be 1 row if($count==1){ // Register $myusername, $mypassword and redirect to file "login_success.php" session_register("myusername"); session_register("mypassword"); header("location:login_success.php"); } else { echo "Wrong Username or Password"; } ob_end_flush(); ?> (Note: All of the mySQL database info is filled in on my version) Aslo, the author gives a php5 version and a normal php version. I have tried both and gotten the same error. If anyone knows why this is happening help is really appreciated.

  • Virtual class problem

    - by ugur
    What i think about virtual class is, if a derived class has a public base, let's say, class base, then a pointer to derived can be assigned to a variable of type pointer to base without use of any explicit type conversion. But what if, we are inside of base class then how can we call derived class's functions. I will give an example: class Graph{ public: Graph(string); virtual bool addEdge(string,string); } class Direct:public Graph{ public: Direct(string); bool addEdge(string,string); } Direct::Direct(string filename):Graph(filename){}; When i call constructor of Direct class then it calls Graph. Now lets think Graph function calls addedge. Graph(string str){ addedge(str,str); } When it calls addedge, even if the function is virtual, it calls Graph::edge. What i want is, to call Direct::addedge. How can it be done?

  • c# Attribute Question

    - by Petoj
    Well i need some help here i don't know how to solve this problem. the function of the attribute is to determine if the function can be run... So what i need is the following: The consumer of the attribute should be able to determine if it can be executed. The owner of the attribute should be able to tell the consumer that now it can/can't be executed (like a event). It must have a simple syntax. This is what i have so far but it only implements point 1, 3. [AttributeUsage(AttributeTargets.Method, AllowMultiple = false)] public class ExecuteMethodAttribute : Attribute { private Func<object, bool> canExecute; public Func<object, bool> CanExecute { get { return canExecute; } } public ExecuteMethodAttribute() { } public ExecuteMethodAttribute(Func<object, bool> canExecute) { this.canExecute = canExecute; } }

  • Xsl mime type problem

    - by savruk
    Hi, I have a busybox with lighttpd running on as http server. My problem is while firefox and opera can get the page with applied xsl, Arora(webkit) can not. Here is the script I use to get it work: <html> <head> <script> function loadXMLDoc(dname) { if (window.XMLHttpRequest) { xhttp=new XMLHttpRequest(); } else { xhttp=new ActiveXObject("Microsoft.XMLHTTP"); } xhttp.open("GET",dname,false); xhttp.send(""); return xhttp.responseXML; } function querySt(ji) { hu = window.location.search.substring(1); gy = hu.split("&"); for (i=0;i<gy.length;i++) { ft = gy[i].split("="); if (ft[0] == ji) { return ft[1]; } } } function displayResult() { xml=loadXMLDoc("sample.xml"); alert(xml)//Gives [object Document] $scan=querySt("scan"); $sub = querySt("sub"); xsl=loadXMLDoc("sample.xsl"); alert(xsl)//Gives Null // code for IE if (window.ActiveXObject) { ex=xml.transformNode(xsl); document.getElementById("example").innerHTML=ex; } // code for Mozilla, Firefox, Opera, etc. else if (document.implementation && document.implementation.createDocument) { xsltProcessor=new XSLTProcessor(); xsltProcessor.importStylesheet(xsl); xsltProcessor.setParameter(null,"scan",$scan) if($sub != ""){ xsltProcessor.setParameter(null,"sub",$sub) } resultDocument = xsltProcessor.transformToFragment(xml,document); document.getElementById("example").appendChild(resultDocument); } } </script> </head> <body onload="displayResult()"> <div id="example" ></div> </body> </html> I tried to see if it load xsl well and put an alert(xsl) but it gives null. Other browser can get xml and xsl files perfectly. What can be the problem? Thanks P.S: It runs well on my local server with all browser.

  • Starting with versioning mysql schemata without overkill. Good solutions?

    - by tharkun
    I've arrived at the point where I realise that I must start versioning my database schemata and changes. I consequently read the existing posts on SO about that topic but I'm not sure how to proceed. I'm basically a one man company and not long ago I didn't even use version control for my code. I'm on a windows environment, using Aptana (IDE) and SVN (with Tortoise). I work on PHP/mysql projects. What's a efficient and sufficient (no overkill) way to version my database schemata? I do have a freelancer or two in some projects but I don't expect a lot of branching and merging going on. So basically I would like to keep track of concurrent schemata to my code revisions. [edit] Momentary solution: for the moment I decided I will just make a schema dump plus one with the necessary initial data whenever I'm going to commit a tag (stable version). That seems to be just enough for me at the current stage.[/edit] [edit2]plus I'm now also using a third file called increments.sql where I put all the changes with dates, etc. to make it easy to trace the change history in one file. from time to time I integrate the changes into the two other files and empty the increments.sql[/edit]

  • Help using Horner's rule and Hash Functions in JAVA?

    - by Matt
    I am trying to use Horner's rule to convert words to integers. I understand how it works and how if the word is long, it may cause an overflow. My ultimate goal is to use the converted integer in a hash function h(x)=x mod tableSize. My book suggests, because of the overflow, you could "apply the mod operator after computing each parenthesized expression in Horner's rule." I don't exactly understand what they mean by this. Say the expression looks like this: ((14*32+15)*32+20)*32+5 Do I take the mod tableSize after each parenthesized expression and add them together? What would it look like with this hash function and this example of Horner's rule?

  • Building a Hashtag in Javascript without matching Anchor Names, BBCode or Escaped Characters

    - by Martindale
    I would like to convert any instances of a hashtag in a String into a linked URL: #hashtag - should have "#hashtag" linked. This is a #hashtag - should have "#hashtag" linked. This is a [url=http://www.mysite.com/#name]named anchor[/url] - should not be linked. This isn&#39;t a pretty way to use quotes - should not be linked. Here is my current code: String.prototype.parseHashtag = function() { return this.replace(/[^&][#]+[A-Za-z0-9-_]+(?!])/, function(t) { var tag = t.replace("#","") return t.link("http://www.mysite.com/tag/"+tag); }); }; Currently, this appears to fix escaped characters (by excluding matches with the amperstand), handles named anchors, but it doesn't link the #hashtag if it's the first thing in the message, and it seems to grab include the 1-2 characters prior to the "#" in the link. Halp!

  • IE image map remains clickable behind another div

    - by Ryan Giglio
    I have an Image Map of the United States. When you click on a state, the map fades out and a map of that state appears with an image map of the area codes in the state. In Firefox, Safari, and Chrome, the state map becomes clickable and the United States map becomes unclickable until you close the sate popover. However in Internet Explorer, the United States map remains clickable through the state popover, and I cannot click on any area codes. Here is my javascript: $(document).ready(function() { $("#usMap").html(); $("#usMap").load("/includes/us_map.inc"); }); $('area').live('click', function() { var state = $(this).attr("class"); var statePopover = $("<div id='statePopoverContainer'><a id='popoverCloseButton'>Close State</a><div id='statePopover'></div></div>"); $("#usMap").append(statePopover); $("#usMapImage").fadeTo('slow', 0.2); $("#statePopover").load("/includes/stateMaps/" + state + ".html"); }); $("#popoverCloseButton").live('click', function() { $("#statePopoverContainer").remove(); $("#usMapImage").fadeTo('slow', 1); }); I am loading the map on document ready because if you don't have Javascript, something else appears. And here is the CSS for all things related: div#usMap { width:676px; height:419px; text-align: center; position: relative; background-color:#333333; z-index: 1; } img#usMapImage { z-index: 1; } area { cursor: pointer; } div#statePopoverContainer { width:100%; height:100%; z-index:5; position:absolute; top:0; left:0; } a#popoverCloseButton { position:absolute; right:0; padding-right:5px; padding-top:5px; color:#FFFFFF; cursor:pointer; } You can see this happening at http://dev.crewinyourcode.com/ Login with beta/tester

  • Using hash functions with Bloom filters

    - by dangerstat
    Hi, A bloom filter uses a hash function (or many) to generate a value between 0 and m given an input string X. My question is how to you use a hash function to generate a value in this way, for example an MD5 hash is typically represented by a 32 length hex string, how would I use an MD5 hashing algorithm to generate a value between 0 and m where I can specify m? I'm using Java at the moment so an example of to do this with the MessageDigest functionality it offers would be great, though just a generic description of how to do about it would be fine too. Thanks

  • How to correctly pop a modeless dialog from console using MFC

    - by Vertilka
    I need to create a console application that has a main() function and pop a modeless dialog, so the console can still work in parallel to the modeless dialog (do other work, like communicating with the modeless dialog). Whatever i tried, i could only pop a modal dialog. (where the console is in hold till the modal dialog close itself). When switching to modeless dialog using Create() and ShowWindow() the dialog is displayed without its controls and it freeze / block (you can see the hourglass cursor). 1) i tried to pop the modeless dialog from the main() function 2) i tried to pop the modeless dialog from the InitInstance() of a CWinApp derived class In all cases the modeless dialog freeze / block. I believe this is a one line solution. TNX,Vertilka
