TIP: Hiding the Windows Live Messenger icon

Jon Hibbins — Thu, 14 Jan 2010 16:24:00 +0000

If you use Windows Live Messenger a lot, you’ll have noticed that the icon now resides on the taskbar, where you can easily change status and quickly send an IM to someone. If you prefer to keep Windows Live Messenger in the system tray, where it’s been for previous releases, just close Windows Live Messenger, edit the shortcut properties and set the application to run in Windows Vista compatibility mode.

Zend Server CE on OSX 10.6 Snow Leopard

Jon Hibbins — Sun, 18 Oct 2009 11:36:08 +0000

When I installed Zend Server CE on OSX 10.6 Snow Leopard the admin interface failed, the following fixed the issue :

1. Download this: Watchdog update

2. Backup watchdog with the command

sudo mv /usr/local/zend/bin/watchdog /usr/local/zend/bin/watchdogOLD

3. Extract the new watchdog to /usr/local/zend/bin/ (I used the go to folder in finder, if you can view hidden files)

4. Run the following command to restart the Zend server

sudo /usr/local/zend/bin/zendctl.sh restart

4 Coding tips

Jon Hibbins — Wed, 26 Aug 2009 09:49:00 +0000

1: Delete It !
If a chunk of code comment or class is not used, don’t comment it out, just delete it.

2: Write clear code.
“make sure you document code that’s hard to understand”. Question: why is the code hard to understand?

3: Comment
Comments can indeed be useful but mostly as a summary of action

4: Don’t Repeat Yourself
Duplication is bad. If you have more than 4-5 lines of code that do the same thing in a single class, refactor to remove duplication.

Check if a Javascript function exists

iPhone 3.0

Jon Hibbins — Tue, 17 Mar 2009 22:41:20 +0000

Apple has announced the iPhone 3.0 software update which includes an updated Software Development Kit (SDK) with over 1,000 completely new APIs.

Here are a few highlighted features:

Search your iPhone
Cut, copy, and paste
Send photos, contacts, audio files, and location via MMS*
Read and compose email and text messages in landscape

And yes, I am running it (I have an Apple Developer Account), and so far I found one bug (on safari re-highlighting the address bar can sometimes make the address disapear) and an un-announced fearure (the call history list is now much more verbose)

SVN Port TCP Port is 3690

Jon Hibbins — Thu, 12 Feb 2009 10:29:43 +0000

If you need to access SVN remotely, by default it runs on port TCP port 3690, so you need to make sure it is open in your firewall etc.

SQL Server Schema,Table,Function and Stored procedure Auditing

Jon Hibbins — Wed, 17 Dec 2008 16:09:47 +0000

If you like to know what’s changing on your SQL Server then the following code creates an audit table and the associated trigger for logging the changes

The Audit Object Table

CREATE TABLE [dbo].[AuditObjects](
 [EventID] [int] IDENTITY(1,1) NOT NULL
,[EventData] [xml] NULL
PRIMARY KEY CLUSTERED (
   [EventID] ASC
) WITH (IGNORE_DUP_KEY = OFF) ON [PRIMARY]
) ON [PRIMARY]

And the associated Trigger

CREATE TRIGGER [TriggerAuditObjects]
ON DATABASE
FOR DDL_DATABASE_LEVEL_EVENTS
AS
INSERT INTO [dbo].[AuditObjects](EventData)
SELECT EVENTDATA()
GO
ENABLE TRIGGER [TriggerAuditObjects] ON DATABASE

You can now use xpath queries to analyse the data

Search Stored Procedures

Jon Hibbins — Fri, 05 Dec 2008 09:21:50 +0000

Ever had the need to search stored procedures to find redundant tables or text that needs replacing or re-factoring ?

Here’s a script to help (Sorry for the cursor, I’m sad with myself for using it )

-- Search string
DECLARE @SearchString nvarchar(50)
SET @SearchString = 'Search String'
 
-- Required Declares
DECLARE @getdbname sysname
DECLARE @sqlstm nvarchar(1000)
DECLARE SeachCursor cursor FOR 
-- Get All The Names into the SeachCursor
SELECT '['+name+']' FROM [master].[dbo].[sysdatabases] ORDER BY name 
OPEN SeachCursor
-- Add the Search Pattern
SET @SearchString = '%' + @SearchString + '%'
--Get the first Name
FETCH NEXT FROM SeachCursor INTO @getdbname
WHILE @@FETCH_STATUS=0
	BEGIN
	--set the statement to define the search condition, with variables
	SET @sqlstm = '
	SELECT [SP].[Specific_Catalog] AS [Database_Name], [SP].[Routine_Name] AS [Stored Procedure Name],[SP].[Routine_Definition] AS [Routine_Definition]
	FROM '+ @getdbname+'.[Information_Schema].[Routines] AS [SP]
	WHERE PatIndex('+''''+@SearchString+''''+', [Routine_Definition]) > 0'
	--Execute the Query
	EXEC (@sqlstm)
	FETCH NEXT FROM SeachCursor INTO @getdbname
	END
--Close the Cursor and Deallocate it from memory
CLOSE SeachCursor
DEALLOCATE SeachCursor
