  • HTML stops at a PHP script made to connect to a mysql database. No errors printed.

    - by DavidR
    I'm trying to set up a login script for PHP using the tutorial on this site. The problem is that the site stops when it hits these lines, no error, no text: <?php $conn = mysql_connect('localhost', 'root', 'password') or die('error line7' . mysql_error()); mysql_select_db('mydb', $conn) or die('error line8' . mysql_error()); ?> If I take out these lines, the rest of the html runs perfectly. I've double checked my passwords and everything, nothing is working. I know very little about php and mysql other than what I've learned trying to set this up.

  • dojo.gfx matrix transformation

    - by Linus
    Matrix transformations has got my head spinning. I've got a dojox.gfx.group which I want to be draggable with Mover and then be able to rotate it around a certain point on the surface. My basic code looks like this: this.m = dojox.gfx.matrix, . . . updateMatrix: function(){ var mtx = this.group._getRealMatrix(); var trans_m = this.m.translate(mtx.dx, mtx.dy); this.group.setTransform([this.m.rotateAt(this.rotation, 0, 0), trans_m]); } The rotation point is at (0,0) just to keep things simple. I don't seem to understand how the group is being rotated. Any reference to simplistic tutorial on matrix transformations would also help. The ones I've checked out haven't help too much.

  • Overriding the admin Media class

    - by shacker
    Given an admin media class that sets up a rich text editor, like: class TutorialAdmin(admin.ModelAdmin): fields... class Media: js = ['/paths/to/tinymce.js',] I would like the ability to selectively override js depending on a field value in the model it references. I've added a "use_editor" boolean to the Tutorial model. The question is, how can I detect whether the current instance has that bool set? I'd like to end up with something like: class Media: if self.use_editor: js = ['/path/to/tinymce.js',] else: js = '' Ideas? Thanks.

  • Developing browser plug-ins?

    - by JavaMan
    I have a project that I'd like to try that involves developing an internet browser plug-in. I have knowledge in Java and DHTML, but nothing in the world of browser plug-in development. I thought I would just ask here then what is the most efficient way to develop a browser plug-in? If possible, I'd like to streamline the process so that getting the plug-in to work in different browsers involves as little work as possible. Can this be done? I'm not asking for a tutorial like the trolls do, just a few pointers that's all. I don't waste mine or anyone else's time.

  • Can anyone recommend a primer to Erlang?

    - by Till
    I've recently found myself getting more and more interested in Erlang. I've purchased a book (Programming in Erlang) and started reading up on the basics. Reading books is time consuming so I am looking to shortcut this a bit and go back to the book later. What I lack is a good introductory tutorial. Kind of like, hands on, this is what you need to get started in Erlang, these are best practices, this is how you organize code and this is how you do a small project. I've googled this topic extensively and haven't had much luck. ;)

  • Creating a loading screen in HTML5

    - by espais
    I am having some issues finding a decent tutorial for generating a loading style screen with regards to HTML5. To be quite honest I'm not sure exactly where to begin... My project is essentially a simple HTML5 game, where I'll be loading in various sprite sheets and tilesets. They'll be reasonably small, but I'd like to show a little loading spinner instead of a blank screen while all the resources are loaded. Much appreciated if somebody could point me in the right direction, be it decent links or code samples to get me going...my Google-fu is lacking today! For clarification, I need to figure out how to load the resources themselves, as opposed to finding a spinner. For instance, how to calculate that X% has loaded.

  • Auto-complete/suggestion popup menu in GtkTextView

    - by Tyler
    I'm trying to create a system that will allow me to respond to the current text and auto-complete/suggest what should come next. For example if the user starts to type "Batm" then the system would respond with a menu showing the full completed word "Batman". Think of an IDE like Eclipse or Visual Studio and you get the idea. I understand how to create a popup menu in Gtk+ but what I don't understand is the following: How do I grab the word that the user is currently typing from a GtkTextView (or SourceView) so that I can do a lookup and offer suggestions? How do I position the menu in such a way that it sits next to the current text item (like it would in an IDE)? If anyone could offer suggestions or even a link to a tutorial or example on how to do this correctly I would be forever grateful. As always thanks for you help! Programming language: C

This is my approach: Generate pojo classes from my sybase database using hibernate in eclipse Use these pojo classes to generate the schema in mysql database Then somehow migrate the data from sybase to mysql I guess this approach should work???

  • Need example of how to create/manipulate image pixel data with iPhone SDK

    - by whiskeyspider
    Looking for a simple example or link to a tutorial. Say I have a bunch of values stored in an array. I would like to create an image and update the image data from my array. Assume the array values are intensity data and will be updating a grayscale image. Assume the array values are between 0 and 255 -- or that I will convert it to that range. This is not for purposes of animation. Rather the image would be updated based on user interaction. This is something I know how to do well in Java, but am very new to iPhone programming. I've googled some information about CGImage and UIImage -- but am confused as to where to start. Any help would be appreciated.

  • JQuery with SMARTY php

    - by out_sider
    This might seem a very noob question but I haven't found the answer yet. I have a header.tpl file which contains xhtml code. I want to and some java script to it using jquery. But my problem is that it simple doesn't happen what I tell it to do. Because the page hoster comiples php with SMARTY I had to make a small change to the block script, which was had the {literal} {/literal}. But the rest seems ok. Btw the jquery.js is on the same folder as the header.tpl. File header.tpl http://feupload.fe.up.pt/get/SQWJvybQkDCmjEG PS: I event replaced all the code by the getstarted tutorial on the jquery homepage and added the {literlar} {/literal} (otherwise it would give an error) and it steel didn't work

  • hg access control

    - by andreas buykx
    Me and a couple of colleagues are starting to use mercurial, and we want to have a shared repository that would contain our QC-ed changes. Each of the developers hg clones the repository and pushes his changes back to the shared repository. I've read the HG init tutorial and skimmed through the red bean book, but could not find how to control who is allowed to push changes to the shared repository. Can someone tell me how to set up a hg repository such that it only allows specified users (by unix userids) to push changes?

  • Django models & Python class attributes

    - by Geo
    The tutorial on the django website shows this code for the models: from django.db import models class Poll(models.Model): question = models.CharField(max_length=200) pub_date = models.DateTimeField('date published') class Choice(models.Model): poll = models.ForeignKey(Poll) choice = models.CharField(max_length=200) votes = models.IntegerField() Now, each of those attribute, is a class attribute, right? So, the same attribute should be shared by all instances of the class. A bit later, they present this code: class Poll(models.Model): # ... def __unicode__(self): return self.question class Choice(models.Model): # ... def __unicode__(self): return self.choice How did they turn from class attributes into instance attributes? Did I get class attributes wrong?

  • Create a service that connects to remote database and uses public key encryption

    - by Leedsoft Solutions
    I have been searching all day and reading many tutorials and still I am confused. I am working on a project that has the following requirements as specified by the client (customer - not to be confused with client app): Connect to a remote server and verify that connection was successful. Connect to Web service on said server via SOAP. Authenticate with service using public key encryption Upon successful authentication, push a list of products and categories to a MSSQL database on remote server via the Web service. The client is a Winforms application written in C#. So far, I have created a WCF Service Application with separate services for the products and categories but I cannot figure the rest out. Can anyone point me in the direction of a tutorial or tutorials that cover these requirements? Many thanks in advance! Joe

  • xgettext vs gettext

    - by Kentor
    I have a few questions: I know what gettext is. I've read a few posts where they mentioned xgettext and was curious as to what is the difference between the two. How can I install xgettext on Windows? And finally, does anybody have a tutorial on how to install the library php-gettext http://savannah.nongnu.org/projects/php-gettext/ (this one usually doesn't come with PHP) I've read about it in an article but I'm not sure how to get it working in Windows. The thing is, sometimes when you make changes, you need to restart Apache to see the new data with the gettext that comes with PHP (but with the library you don't need to restart it) so I wanted to use the library for development. Thanks!

  • If I already know Perl Is Python worth learning?

    - by Garett
    I'm all for learning and continual improving one’s self, and I believe you should have as many tools as possible in your toolbox. However, I was wondering if it was worth it learning Python, since I already know a couple of dynamic interpreted languages, including Perl. My background is mostly C/C++/Java/C#, but I’ve programmed in Perl quite a bit over the years. I recently read Dive Into Python, as well as the tutorial for the Django framework for a new project where Python was suggested. However, I kept finding myself thinking that I can still accomplish much of the same stuff with Perl, so I’m not sure when I would choose a Python approach over one that I’m already familiar with. This is by no means meant to start any kind of language war, and I do recognize that language choice is quite subjective. I just wondering when one would make such a choice.

  • How to view existing data in Core Data?

    - by mshsayem
    Well, may be this question is silly, but I couldn't find a way (except programmatically). I built a project (for iPhone OS 3.0) which uses Core Data. The xcdatamodel file shows the schema description, but I want to see the data in tabular form (like the management studio for mssql server or phpmyadmin for mysql). Is there any way (except coding)? What is that? Also, which file (in disk/device) those data are stored into? [ I built the tutorial (from apple) on Core Data, named Locations. They used this line somewhere in the code: NSURL *storeUrl = [NSURL fileURLWithPath: [[self applicationDocumentsDirectory] stringByAppendingPathComponent: @"Locations.sqlite"]]; But, I did not see any "xxxxx.sqlite" file in project location (nor in the disk).]

  • c++ undefined references with static library

    - by stupid_idiot
    hi guys i'm trying to make a static library from a class but when trying to use it i always get errors with undefined references on anything. the way i proceeded was creating the object file like g++ -c myClass.cpp -o myClass.o and then packing it with ar rcs myClass.lib myClass.o there is something i'm obviously missing generaly with this.. i bet it's something with symbols.. thx for any advices, i know it's most probably something i could find out if reading some tutorial so sorry if bothering with stupid stuff again :) edit: myClass.h: class myClass{ public: myClass(); void function(); }; myClass.cpp: #include "myClass.h" myClass::myClass(){} void myClass::function(){} program using the class: #include "myClass.h" int main(){ myClass mc; mc.function(); return 0; } finally i compile it like this: g++ -o main.exe -L. -l myClass main.cpp

  • rails 3 cookies

    - by ralph
    I have a simple app where users type in stuff in a text filed to get various results. I would like a feature where if a user enters something and then closes the browser tab, the next time they come, I can show them their previous/recent searches. This will persist even if they close the whole browser and open it again. I believe this can be done by help of cookies. Are there some good rails3 gems for using cookies or any simple tutorial that could guide me in a direction?

  • Deriving PathInfo class in web routes?

    - by drozzy
    I am reading the web-routes tutorial in Happstack, and I have no idea what this is doing: $(derivePathInfo ''Sitemap) class PathInfo a where toPathSegments :: a -> [String] fromPathSegments :: URLParser a The doc simply says: we use template-haskell to derive an instance of PathInfo for the Sitemap type. but where does it "store" it? I thought haskell had no state, and is PathInfo our own thing, or is it part of happstack? If someone could explain this, for dummies? Thanks.

  • hash password in SQL Server (asp.net)

    - by ile
    Is this how hashed password stored in SQL Server should look like? This is function I use to hash password (I found it in some tutorial) public string EncryptPassword(string password) { //we use codepage 1252 because that is what sql server uses byte[] pwdBytes = Encoding.GetEncoding(1252).GetBytes(password); byte[] hashBytes = System.Security.Cryptography.MD5.Create().ComputeHash(pwdBytes); return Encoding.GetEncoding(1252).GetString(hashBytes); } EDIT I tried to use sha-1 and now strings seem to look like as they are suppose to: public string EncryptPassword(string password) { return FormsAuthentication.HashPasswordForStoringInConfigFile(password, "sha1"); } // example output: 39A43BDB7827112409EFED3473F804E9E01DB4A8 Result from the image above looks like broken string, but this sha-1 looks normal.... Will this be secure enough?

  • Integrating Prolog with C#

    - by TK
    Does anyone know of a nice (and preferably free) way to integrate Prolog and C#? Im looking to create a Prolog dll or similar to call from my managed code, and retrieve an answer once all the processing has been complete. Im looking for it to be predominantly one sided (c# calls Prolog). I have seen this question which talks about Prologs real world usage but I was wondering if anyone had either any experience with c# & Prolog? or a nice tutorial/article?
