I follow the lamp stack of Linux, Apache, MySQL and PHP
I do this mainly because of cost, resources, a friendly and knowledged community can be easily found to help guide you on your way. This stack is also very wide used and for good reasons.
So to your questions
1) What technologies should I start.
2) How these networking sites are built, with user login etc.
This is a big question but the short answer is sessions. Sessions store values placed in them by the scripts you write, like a posted form sends username and password to a server. a script on the server scrubs the input, to protect from hackers, and validates the info. If its correct then a session variable(s) is(are) set so you can maintain persistant data between page request. Session related variables can include user name, security level, a saved shopping cart, etc.
3) Is there any helping documents which I can refer to.
To numerous to count. This site, "Code Project" is a truly great resource for code snips and guidance. And I do not get paid to write this...well I do not think I do...maybe I should ask also: http://www.php.net/ , http://www.mysql.com/ , http://www.w3schools.com/html/ , http://www.w3schools.com/js/ , http://jquery.com/ , and a place to see where online applications are going sites like this http://html5demos.com/ give you a glimps of whats possible
4) What database technologies that I should learn.
MySQL is the most common db engine you will find on the net.
Ok, so you will need to provide us with more information other then 'It aint working'.
Here are some steps that might give you a clue as to what is wrong:
- Look through the IIS access files, to see if the request to the service are giving status code 200 or 204 (if not the service is throwing an error, code 503)
- Look through the webservice logs, if any, to see if it tells you what is wrong
- Make sure you are calling the webservice right, keep in mind SOAP services require POST data in XML format.
Currently, I'm working on a flex project with .Net integration via web service. I'm trying to bind the web service result to a xmllist but always fail to do so. Can anybody provide me ways on how to accomplish such? I have tried to cast the result to Xml in the web service object event handler but still got no luck. I have also tried to set the resultFormat to "e4x" but still it doesn't work.
Your help will be greatly appreciated. Thanks much.
Hello anybody knows how to match the height of my sidebar area to my content area? I just want my sidebar to be the same height as my content area(the posting area). I want it so that my sidebar background will extend all the way down matching the height of the content area, even the sidebar is not having a widget in it. Here is the site http://bloomtheflowercompany.yenius.com/ the green background should extend all the way down even if it has no widget.
One thing which might fit your needs is to enclose both sidebar and content in a <div>, then give your sidebar a height of 100%. That way, the main content "drives" the height of the enclosing div, and the sidebar follows. CSS is cheap, so have a play!
