If you want to check whether a browser has HTML 5 geolocation support enabled and display a warning message to the user if it is not, then this function should help you out.
$('#map_canvasâ€™).text('Your browser does not support HTML 5 geolocation. ');
In this example I check to see if the navigator.geolocation method is available. If not then I use a jQuery command to update the div that would normally house the Google Map by adding warning text for the user.
Next we must download the Cycle plugin and include it from your computer.
Next step is to define your slideshow files in HTML. Simply write your img tags into a slideshow div tag.
fx: 'fade' // choose your transition type, ex: fade, scrollUp, shuffle, etc...
I've been having the problem of trying to output generated HTML into a ruby view template in a similar fashion to this:
<%= generated_html %>
The problem is in Rails 3 you no longer need the "h" function which escapes HTML. This is now done automatically.
The solution is to tell rails that this is safe HTML and you want to unescape the output using the "html_safe" function as follows:
<%= generated_html.html_safe %>
I have recently reinstalled Ruby on Rails 3.0.0 and created a new Rails project in NetBeans 9.6.1
I could not migrate my database, or any other rake tasks for that matter. I kept getting the error: "db:migrate" task does not exist
The solution is to right click your project select "Run/Debug Rake Task" and then click the button titled "Refresh Tasks".
Once this is done you should see a list of all your rake tasks. After this you can simply re-run the db:migrate task and it will work.
If you are having the problem that the PHP Installer MSI is not asking for your web server type and therefore not updating your server configuration or not installing the correct libs such as "php5apache2_2.dll" then you are probably using the wrong MSI.
All of the MSI installers are on the http://windows.php.net/download/ page. You do not want to use the VC9 installers. You need to use the VC6 x86 Thread Safe installer. This is usually the last option, per version.
The link to the latest safe MSI is here: PHP 5.3 VC6 Thread Safe MSI
I recently upgraded my PHP version to 5.3 and afterwards could not connect to MySQL. I was getting the following error in my PHP error log: PHP Warning: mysql_connect():  A connection attempt failed because the connected party did not (trying to connect via tcp://localhost:3306)
The solution is to do with Windows enabling IPv6 support while MySQL does not support this yet. 'localhost' is being converted to ::1 instead of 127.0.0.1, the solution to this is simple.
Go the the following directory: C:\Windows\System32\drivers\etc
Allow yourself full access to the hosts file by right clicking it and clicking properties.
Next go to the security tab and click the big "Edit" button.
Click on the "Users" group. Below this check the "Full Control" box and then save the changes.
Now that you have access to the file, open the hosts file with a text editor such as notepad.
Comment out the ::1 line with a # so the file will look something like:
# Copyright (c) 1993-2006 Microsoft Corp.
# This is a sample HOSTS file used by Microsoft TCP/IP for Windows.
# This file contains the mappings of IP addresses to host names. Each
# entry should be kept on an individual line. The IP address should
# be placed in the first column followed by the corresponding host name.
# The IP address and the host name should be separated by at least one
# Additionally, comments (such as these) may be inserted on individual
# lines or following the machine name denoted by a '#' symbol.
# For example:
# 22.214.171.124 rhino.acme.com # source server
# 126.96.36.199 x.acme.com # x client host
Once you are done, save the file and try to access your PHP page again that is using MySQL. It should work immedietley.
<input onclick="this.select();" type="text" name="title" value="Title...">
I have recently been playing with mod_rewriting my web application URLs. I find that they worked perfectly on my live host but just wouldn't work on localhost.
This solution works for me: You have to open the httpd.conf Apache configuration file.
Locate this line and remove the "#":
#LoadModule rewrite_module modules/mod_rewrite.so
Finally search the file for "AllowOverride None".
This phrase will appear 7 times in the file, you want the second one and change the "None" to "All".
The comment above the line is:
# AllowOverride controls what directives may be placed in .htaccess files.
# It can be "All", "None", or any combination of the keywords:
# Options FileInfo AuthConfig Limit

Do I Need a Website?
In a few short years all businesses will have a website. In fact it is quite uncommon to see a business without a website even these days. I will sum up in a few short points why having a website is a great addition to your business and will pay for itself in the long run.
Once your website is built and online it acts as free advertising. Nearly 1.5 million Google searches are done every minute according to recent statistics. This means there are literally thousands of people out there able to find your website, without even beginning to consider other search engines such as Yahoo or Bing.
A good looking website inspires a lot of trust in potential customers. Many people browse the internet to research possible choices when looking for a product or service. Having a professional user-friendly website can make all the difference between making a sale and giving business away to your competitors.
New Communication Channels
A website offers a whole new level of communication between your company and your customers. Many people do not enjoy speaking on the phone to a company; your website will offer alternatives such as email, address to mail or even live chat online.
A website can even be used to let customers type in how they feel and leave comments which you can reply to, letting the customer know you care for them and value their custom.
Keep Customers Up To Date
A website can be used to launch important news announcements about your company straight to the public through your blog, news feeds or even a monthly newsletter.
Time is Money
A well used clichÃ© in the business world â€“ but often this is proven true. Having a website can improve business efficiency a hundredfold. Instead of having scraps of paper lying around detailing invoices and day to day notes, store these online where they are always available to you, in your office or at home.
Once you have a website helping you run the business you can do all sorts of interesting things such as run reports on sales, backup client information and provide news updates to your staff.
To wrap all of this information up for you, the main point of a business website is to pull in more customers and sell more of your product. Websites are quick and easy to setup; once they are online your customer base will begin to grow immediately, with the handy side effects of bringing in more money and growing your business quicker than you thought possible.
