iPhone caps lock mode

Jon Hibbins — Thu, 15 Apr 2010 02:01:17 +0000

The iPhone does have a caps lock mode built in, but it’s disabled by default. To enable it, go to Settings > General > Keyboard and turn on “Enable Caps Lock.” Now whenever you need to type in all caps, simply double-tap the shift key to engage caps lock.

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.

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

If you want to check if a Javascript function exists before you attempt to call it and get an error try:

// Check if a Javascript function exists and run it if it does
if(typeof window.Function == 'function') {
    Function();
}

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.

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

iPhone Developer Provision Issue on Device

Jon Hibbins — Wed, 27 Aug 2008 11:40:57 +0000

After a number of compile to iPhone device issues, specifically: “entitlement ‘application-identifier’ has value not permitted by provisioning profile” and “Command /usr/bin/codesign failed with exit code 1″, I have worked out you can have one and only one developer provision and developer application on the iPhone at a time otherwise you get installation errors etc…

I also had to have the correct Bundle Identifier in the Info.plist file and make sure the ‘Code Signing Identity’ and ‘Code Signing Provisioning Profile’ was also correct.

Hopefully this is useful to someone, Good Luck!!!
