Web Service using JSONP from External Domain – PHP – JQuery

dan — Fri, 03 Feb 2012 15:57:31 +0000

You may want to look at this previous post where I setup a PHP Webservice that uses JSON PDO – Accessed by JQuery AJAX

OK, so this code will use php to generate the JSON code that will get delivered over the internet to the JSONP (JSON Padding) client on an external domain. This allows your webservice to be available too whoever wants to call it.

Here is the PHP Code: (Not all of it, but enough to get the idea)

//http://SERVER_domain.com/webservice.php
private function GetTriviaTag($row) {
	$t = new Tag();
	$t->id = $row['id'];
	$t->triviaid = $row['triviaid'];
	$t->tagid = $row['tagid'];
	return $t;
}
public function GetWhere($where) {
	$retArray;
 
	$sql = "SELECT * FROM trivia_tags WHERE {$where}";
	foreach ($this->pdo->query($sql) as $row)
	{
		$retArray[] = $this->GetTriviaTag($row);
	}
	return $retArray;
}
$where = " (1 = 1)";  // THIS WILL SELECT ALL
$tarray = GetWhere($where);
 
//OUTPUT JSON:
header('Content-type: application/json');
echo $_GET['callback'];  // <-- THIS IS IMPORTANT FOR EXTERNAL DOMAIN ACCESS!!!
echo "(" . json_encode($tarray) . ")";

And now, to access it from javascript in an external domain (non – SERVER_domain.com ):

http://CLIENT_domain.com/Test.html:

<html>
	<head>
		<title>Testtitle>
		<script src="http://code.jquery.com/jquery-latest.js">script>
	head>
	<body>
		<div id="triviaQuestions"> loading... div>
		<script>
			$(function() {
				// THE 'callback=?' in this request is IMPORTANT FOR EXTERNAL DOMAIN ACCESS!!!
				$.getJSON('http://SERVER_domain.com/webservice.php&callback=?', function(data) {
					var items = [];
					var htmlResult = "";
					$.each(data, function(key, val) {
						htmlResult += "
Q: "+ val.id +", '"+ val.question +"";
					});
					$('#triviaQuestions').html(htmlResult);
				});
			});
		
	body>

PHP Webservice that uses JSON PDO – Accessed by JQuery AJAX

dan — Fri, 06 Jan 2012 15:25:58 +0000

You may want to look at this previous post where I setup a Web Service using JSONP from External Domain – PHP – JQuery

The HTML that calls the Javascript:

<div id="taglist"></div>
<input name="searchTags" id="searchTags" type="text" />
<input type="button" name="searchtags" onclick="getTags()" value="search"/>
<div id="tagresult">
</div>

The JavaScript (JQuery) AJAX Request and Response Processing:

function getTags()
	{
		var q = $('#searchTags').val();
		$.getJSON('ws.php?type=tag&wN=name&wO=like&wV=' + q, function(data) {
			var items = [];
			var htmlResult = "";
			$.each(data, function(key, val) {
				//As you can see, you can access the JSON (at the bottom of the page) by doing val.PROPERTYNAME:
				htmlResult += "
Add : \"#\" onclick=\"addTag("+ val.id +", '"+ val.getfullname +"'); return false;\">"+ val.getfullname +"";
			});
			$('#tagresult').html(htmlResult);
		});
	}

PHP Code that returns JSON in the PHP file called by the AJAX: (ws.php)

	$ta = new TagAccess();
	$tarray = $ta->GetTagsWhere(" {$whereName} LIKE '%{$whereVariable}%'");
	header('Content-type: application/json');
	echo "",  json_encode($tarray), "";

The GetTagsWhere Helper Function:

    public function GetTagsWhere($where) {
    	$retArray;
 
    	$sql = "SELECT * FROM tags WHERE {$where}";
    	// THE PDO Object was created previously
	foreach ($this->pdo->query($sql) as $row)
	{
		$retArray[] = $this->GetTag($row);
	}
	return $retArray;
    }

JSON Returned:

[{"id":"4","name":"FICTION","parentid":"3","getfullname":"BOOKS > FICTION"},{"id":"5","name":"NON-FICTION","parentid":"3","getfullname":"BOOKS > NON-FICTION"}]

ASP.Net Update Panel – Javascript Event – jQuery Click

dan — Mon, 07 Nov 2011 19:38:47 +0000

I needed to add a onclick event to a textbox in asp.net to change it to remove text from a textbox onClick when it is clicked.
The normal code would look something like this:

1	<asp:TextBox ID="txtStoreLocatorZip" ValidationGroup="CustomerServiceEmail" runat="server" Text="Enter Zip" CssClass="txtStoreLocatorZip_CssClass" />

<script>
        if ($('.txtStoreLocatorZip_CssClass').val() == 'Enter Zip') {
            $('.txtStoreLocatorZip_CssClass').click(function () {
                if ($('.txtStoreLocatorZip_CssClass').val() == 'Enter Zip') {
                    $('.txtStoreLocatorZip_CssClass').val('');
                }
            });
        }
script>

But, this won’t quite work because my textbox is in a UpdatePanel’s ContentTemplate and the javascript is not read on postback.

So, This is what I ended up doing (a simplified version):

<asp:UpdatePanel ID="UpdatePanel2" runat="server" UpdateMode="Conditional">
	<ContentTemplate>
		<asp:TextBox  ID="txtStoreLocatorZip" ValidationGroup="CustomerServiceEmail" runat="server" Text="Enter Zip" CssClass="txtStoreLocatorZip_CssClass" />
	ContentTemplate>
asp:UpdatePanel>

<script>
	Sys.WebForms.PageRequestManager.getInstance().add_endRequest(endRequestHandler);
	function endRequestHandler(sender, args) {
		if ($('.txtStoreLocatorZip_CssClass').val() == 'Enter Zip') {
			$('.txtStoreLocatorZip_CssClass').click(function () {
				if ($('.txtStoreLocatorZip_CssClass').val() == 'Enter Zip') {
					$('.txtStoreLocatorZip_CssClass').val('');
				}
			});
		}
	}
script>

This will add an endRequest handler to the end of the partial page postback so that you can call a nice little function at the end of it.

Hope this helps some people!

Asp.Net – Adding Parameters to CommandType.Text

dan — Wed, 21 Sep 2011 21:35:05 +0000

This is how you add parameters to a standard CommandType.Text SQL call.

This should prevent sql injection attacks.

        Using conSQL = New SqlConnection("CONNECTION STRING TO DATABASE")
            Try
                str = "SELECT * FROM TableName where customerid = @CustomerID and CartType = @CartType"
                cmdSQL = New SqlCommand(str, conSQL)
                cmdSQL.CommandType = CommandType.Text
                cmdSQL.Parameters.AddWithValue("@CustomerID", CustomerID)
                cmdSQL.Parameters.AddWithValue("@CartType", cartType)
                cartcount = cmdSQL.ExecuteScalar()
            Catch ex As Exception
                cartcount = 0
            End Try
        End Using

Free Webcam Security – Dorgem – WinSCP

dan — Sat, 03 Sep 2011 14:59:38 +0000

This is how you setup a free home security webcam using dorgem and winscp.exe.

First Download:

Download WinSCP and install it.http://winscp.net/
Download Dorgem and install it. http://dorgem.sourceforge.net/

Next Configure Dorgem:
Most people are going to want to use the “Web Server” option. This will setup a webserver with your webcam on it…. Pretty straight forward.

But, when I was looking this up, I couldn’t find anywhere that tells you how to use WinSCP. So here I go:

First Configure WinSCP

Open WinSCP
New
Type in all the correct info in session
Make sure you set a default folder under Environment->Directories->Remote Directory
Save… and remember the name of the session
Connect and make sure you set it to remember passwords and everything

Second Configure Dorgem:

Open Dorgem
Preview the source
Click “Store Settings”
- Add
- External Program
- Name it something to remember
- Check Enable
- Command: “C:\Program Files (x86)\WinSCP\winscp.exe” name_of@winscp_session.com /upload %s /defaults
- OK
Click “Capture Now” to test it out.
You should now see a tmp file on the WinSCP server.
If you dont, then you might want to try changing the path to WinSCP in the command or double check the name of the stored WinSCP session in the command.
Then, you can enable motion detection under “options” on the main screen

Hope this helps some people!

Asp.Net VB – Listview – ItemCommand – DataKeys – CommandName – SQL

dan — Mon, 01 Aug 2011 16:56:59 +0000

Here is a basic Listview that has an ItemCommand and ItemDataBound:

Frontend Code:

"lvAddresses" runat="server" DataKeyNames="AddressID,BillingAddressID,ShippingAddressID">
        
            "itemPlaceholder" runat="server">
        
        
            "noborder address_book" cellpadding="0" cellspacing="0">

ASPDotNetStoreFront: Adding Topic to XML Packages or .aspx Pages

dan — Mon, 18 Jul 2011 19:07:22 +0000

This is how you add a DotNetStoreFront’s Topic into a XMLPackage:

select="aspdnsf:Topic('TOPIC_NAME')" disable-output-escaping="yes"/>

Now, if you want to add it to a .aspx or .ascx page on dnsf:

"server" ID="Topic1" TopicName="TOPIC_NAME" />

Simple PHP Pseudo Proxy

dan — Wed, 06 Jul 2011 11:51:56 +0000

This is the code for a simple php pseudo proxy. If you are blocked by a firewall and google cache isn’t working for some reason. You can use a url with this php file in it:


$filename = $_GET["url"];
if (isset($filename))
{
        $handle = fopen($filename, "rb");
        $contents = stream_get_contents($handle);
        print $contents;
        fclose($handle);
}
else
{
        echo "url";
?>




}
?>

Then you can go to where the url is hosted and try something like this:

index.php?url=http%3A%2F%2Fwww.last.fm%2Fuser%2Fdanfolkes%2Fcharts%3Frangetype%3D6month%26subtype%3Dartists

Facebook Website Integration – HTML

dan — Wed, 25 May 2011 15:40:03 +0000

To integrate Facebook on to a website without the use of a facebook app you need these things:

Facebook Page RSS Feed (can be tricky)
Feedburner Account (free,easy) (here)

Once you have both of those things you can do this in feedburner:

Add a new feed (your facebook url)
Go to the publicize tab
Go to BuzzBoost
Sroll down and fill out the form, you will be given html code.

Preview:

And that’s it!
You can now style it up a little bit with some CSS and stuff.

Java – Singleton / Global – Data Access – SQLite

dan — Fri, 20 May 2011 16:21:10 +0000

This will make a Java global object:

import java.io.File;
import java.io.IOException;
 
import com.almworks.sqlite4java.SQLite;
import com.almworks.sqlite4java.SQLiteConnection;
import com.almworks.sqlite4java.SQLiteException;

import com.almworks.sqlite4java.SQLiteStatement;
 
public final class DataAccess {
	// Singleton Stuff
	private static class SingletonHolder { 
	     public static final DataAccess INSTANCE = new DataAccess();
	}
	public static DataAccess getInstance() {
	     return SingletonHolder.INSTANCE;
	}
	// End Singleton Stuff
 
 
	private String HomePath = "";
	private File DBFile;
	private static SQLiteQueue queue;
	private boolean initalized = false;
 
	private DataAccess()
	{
		if (!initalized)
		{
			initDB();
 
			initalized = true;
		}
	}
 
	private void initDB()
	{
		DBFile = locateDBFile();
		DeleteDatabaseContents();
	}
	private File locateDBFile()
	{
		File f = null;
		try{
			HomePath = System.getProperty("user.home");
    	    System.out.println("HomePath: " + HomePath);
    	    f = new File(HomePath + "/database.sqlite");
    	    if (f.canRead())
    	    	return f;
    	    else
    	    {
        	    boolean success = f.createNewFile();
        	    if (success) {
        	        // File did not exist and was created
        	    } else {
        	        // File already exists
 
        	    }
    	    }
    	} catch (IOException e) {
    		//Maybe try a new directory.
    	}
		return f;
	}
 
	private void DeleteDatabaseContents()
	{
		queue.execute(new SQLiteJob<Object>() 
		{
		    protected Object job(SQLiteConnection connection) throws SQLiteException 
		    {
		      // this method is called from database thread and passed the connection
				StringBuilder sb = new StringBuilder();
				sb.append("DROP TABLE IF EXISTS Playlist;");
				sb.append("DROP TABLE IF EXISTS Settings;");
				//sb.append("DELETE FROM someTable;");
				//sb.append("DELETE FROM someTable;");
 
 
				connection.exec(sb.toString());
				return null;
		    }
		});
	}
	public String getHomePath()
	{
		return HomePath;
	}
}

Now you can run this from anywhere:

DataAccess da;
da = DataAccess.getInstance();

PHP API – Google Calendar – Updating Visibility

dan — Fri, 13 May 2011 15:02:15 +0000

The Privacy / Visibility Part:

$event->visibility->value = "http://schemas.google.com/g/2005#event.private";

Here it is in context:

require_once 'Zend/Gdata/Extension/Visibility.php';
require_once 'Zend/Loader.php';
Zend_Loader::loadClass('Zend_Gdata');
Zend_Loader::loadClass('Zend_Gdata_AuthSub');
Zend_Loader::loadClass('Zend_Gdata_ClientLogin');

  $query = $gdataCal->newEventQuery();
  $query->setUser('default');

  $eventFeed = $gdataCal->getCalendarEventFeed($query);

function getEventByURL ($client, $EventURL)

Minecraft – Script – Backup – Update Server – Restart

dan — Mon, 11 Apr 2011 23:57:12 +0000

This is the script I use that will:

Automatically backup minecraft map
Automatically update minecraft server
Automatically restart the server if it stops or dies

#!/bin/bash
while [ true ]; do
   # make md5 of current file for update check.
   md5sum minecraft_server.jar > minecraft_server.jar.md5
   wget -o updatelog.log -N --trust-server-names http://www.minecraft.net/download/minecraft_server.jar
   # display updated status
   if md5sum -c --status minecraft_server.jar.md5 
   then
    echo "Server Up to Date."
   else
    echo "Updated Server!"
   fi
   java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui
   rsync -a --delete --progress /home/dan/serv/minecraft/world "/home/dan/serv/minecraft/bak/world"`eval date +%Y%m%d`""
done

Code Explained:

This will put the server in an infinite loop. You can kill it by hitting Control+C a couple times in a row.

while [ true ]; do

This will make a hash of the current minecraft_server.jar and then download the newest copy using wget.

md5sum minecraft_server.jar > minecraft_server.jar.md5
wget -o updatelog.log -N --trust-server-names http://www.minecraft.net/download/minecraft_server.jar

This will run minecraft in headless mode and with a limit on RAM.

java -Xmx1024M -Xms1024M -jar minecraft_server.jar nogui

This will create a backup of the minecraft world folder in a backup folder. You probably should work on this part.

rsync -a --delete --progress /path/to/minecraft/world "/path/to/minecraft/bak/world"`eval date

Well, hope this helps someone. Have a good day.

Rsync – Speed Limit – Trickle – Slow

dan — Thu, 03 Mar 2011 16:25:58 +0000

Install rsync and trickle:

sudo apt-get install rsync
sudo apt-get install trickle

Now you can run rsync:
This will download at a limit of 80 KB/s from host:

rsync -auvPe "trickle -d 80 ssh" user@host:/src/ /dst/

Explanation of Commands:

-a, --archive               archive mode; equals -rlptgoD (no -H,-A,-X)
-u, --update                skip files that are newer on the receiver
-v, --verbose               increase verbosity
-P  --progress              show progress during transfer
-e, --rsh=COMMAND           specify the remote shell to use
trickle -d 80  = -d rate    Limit the download bandwidth consumption to rate KB/s.

Outlook Rule : Only at Specific Times

dan — Fri, 18 Feb 2011 16:20:29 +0000

Lets say you want to have a rule in outlook send to you only between specific times in the day.

Only after 6pm and before 8am
Only on your lunch hour
When you are not at work

I will explain this by having emails forward to my cell phone, only when I am normally not at the office. (From 6pm-8am) This way, I will be able to receive important emails that may require special outside assistance.

What I do is:

Create a special category called FWD
Use other rules to set messages into the FWD category if I want them forwarded. (Explained Below)
Then, create a rule to run last in the rules list called FWD Rule
*Important Part* This will check the time on the messages, if it’s within the specified hours, it will forward the email (Explained Below)

Creating a Rule to set the FWD Category:
Your Rule Description should look something like this. The important part is that it is assigning it to the FWD Category:

Apply this rule after the message arrives
with 'Emergency from client' in the subject
    and marked as 'high importance'
    and assigned to 'FWD' Category

The Rule that will email header* for UTC times. Make sure it’s assigned to the FWD category. And then FWD it:

Apply this rule after the message arrives
with '2011 23:' or '2011 02:' or ... '2011 10:' in the message header
    and assigned to 'FWD' category
forward it to 'email@example.com'

* This should work on most emails, but if you want to look at the email header Right-click on the message in the Inbox and select Message Options.
* I included the 2011 and the colon to make it more specific.

UTC Time for 6pm – 8am:
Email Header contained:
X-OriginalArrivalTime: 18 Feb 2011 03:23:52.0368 (UTC)
So I searched for:

2011 23:,2011 01:,2011 02:,2011 03:,2011 04:,2011 05:,2011 06:,2011 07:,2011 08:,2011 09:,2011 10:,2011 11:

jQuery – Ajax – Extra Parameters – GET, success

dan — Fri, 11 Feb 2011 16:20:56 +0000

Here is the standard jQuery Ajax call with success handler as well as the ability to pass another parameter to an external function:

	$.ajax({
			type: "GET",
			url: Humancurl,
			dataType: "xml",
			success: function(data){
				NameOfFunctionToParseReturnedData(data,ExtraParameter);
			}
		});

Here is the standard jquery ajax call with success handler:

$.ajax({
  url: 'ajax/test.html',
  success: function(data) {
    $('.result').html(data);
    alert('Load was performed.'+data);
  }
});

Ubuntu Samba – Read-Write-FSTAB-Cifs-Mount

dan — Wed, 26 Jan 2011 21:13:04 +0000

This is my current setup for my two Ubuntu 10.10 (Maverick Meerkat) boxes. One shares a read/write folder to the other. This is my setup. I think the key to this is having the same username on both computers having access to the files.

You might have to run this on the the folder:
sudo chmod -R 777 /path/to/files
sudo chown -R usernameonbothcomputers:usernameonbothcomputers /path/to/files

I installed samba by doing: sudo apt-get install samba

/etc/samba/smb.conf : (on the computer serving the files)

[global]
	workgroup = WORKGROUP
	server string = %h server (Samba, Ubuntu)
	dns proxy = no
 
	interfaces = 127.0.0.0/8 eth0
	bind interfaces only = yes
 
	log file = /var/log/samba/log.%m
	max log size = 1000
	syslog = 0
 
	panic action = /usr/share/samba/panic-action %d
	encrypt passwords = true
	passdb backend = tdbsam
	obey pam restrictions = yes
	unix password sync = yes
	passwd program = /usr/bin/passwd %u
	passwd chat = *Enter\snew\s*\spassword:* %n\n *Retype\snew\s*\spassword:* %n\n *password\supdated\ssuccessfully* .
	pam password change = yes
 
	guest account = nobody
	invalid users = root
	usershare allow guests = yes
 
[MyFiles]
	path = /path/to/share
	writable = yes
	read only = no
	valid users = usernameonbothcomputers

sudo /etc/init.d/smbd reload

/etc/fstab : (on the computer accessing the files)

//SAMBASHAREsSERVERNAME/MyFiles /path/to/mount cifs users,,noatime,username=usernameonbothcomputers,password=theuserspassword 0 0

You should be able to run this to mount all things in your fstab:
sudo mount -a

.Net – Sending Email with In Memory Attachment

dan — Tue, 21 Dec 2010 16:43:32 +0000

This VB.Net code takes the FileUpload control’s PostedFile and without saving it to the filesystem attaches it to an MailMessage and sends an email.

Advantages:

No threading, read/write permissions needed.
One line of code.

Front End:

Code:

Dim m As New MailMessage()
m.Attachments.Add(New Attachment(fileUpload.PostedFile.InputStream, fileUpload.FileName))
