A huge thanks goes out to creator of this compilation Joseph Labrecque.  Thank you for making this compilation and thank you for letting The Compilers submit our song ‘Sleep Tick v2′.  Be sure to read Joseph’s comments about the compilation he so graciously put out for all to enjoy.

I spoke at the last 360|Flex in San Jose, but I’m already more excited for the DC conference, and here’s why.

1. I’m speaking about the most exciting part of the Flash Platform, AIR2
2. Jesse vs. Jesse ( Flash vs Flex throwdown )
3. It’s in Washington DC
4. My band The Compilers will be giving a lunch talk, as well as playing live at one of the parties
5. There is talk of Duanne Nickull’s band 22nd Century playing ( hopefully Sean ‘the flex guy’ too )
6. Doug McCune is giving the opening Keynote speech on Monday
7. I get to hang out with the Flex community

If you haven’t been to a 360 Flex conference yet I highly recommend it.  If you still need help deciding, here are a few conference questions for you.

1. Do you currently work with or have any interest in Adobe Flex?
2. Have you attended a 360 Flex conference yet?
3. Do you want to meet the community loudmouths you’re already following on Twitter?
4. Have you seen who is speaking at 360 Flex DC?
5. Have you ever heard The Compilers play live?
6. Are you still reading this blog post?

The last 360 Flex I spoke at was in San Jose and it rocked.  The city of San Jose bored me to tears, but I felt like I was living inside my twitter feed for three days.  My presentation was on the final day of 360 Flex, so I spent most of the conference preparing, and sitting in a few sessions here and there.  I spent almost half of my time in San Jose working and still met 10-15 of my twitter buddies, not to mention all the new contacts I met.  In a nutshell, if you attend a 360 Flex conference, you will meet the community.  In fact, you’d have to try pretty hard to not meet the Flex community.

If this sounds up your alley, go ahead and register to take advantage of the early adopter ticket price of $450.  I’m not sure when the ticket price will go up to $599, but I know it will so act fast.  If you make it to DC, be sure to find me and introduce yourself.  I promise it will be a good time.

Required Downloads

Before you get to the steps, be sure to download these two files first.

• iPhone1,2_3.1.3_7E18_Restore.ipsw ( this is the OS 3.1.3 restore file )
• blackra1n ( pick the installer that matches your OS )

Restore iPhone 3G to OS 3.1.3

1. Connect your iPhone, open iTunes, then click your iPhone to go to the Summary screen.
2. While holding down Alt ( OSX ) or Shift ( windows ), click the Restore button.  If you held the correct key when clicking restore, you should get a File Open prompt.
3. Select iPhone1,2_3.1.3_7E18_Restore.ipsw that you downloaded earlier and let iTunes do it’s work.
4. After iTunes tries to verify the update, it should throw an error.  This error is normal, so disregard even though iTunes has left your iPhone 3G in restore mode.  Close iTunes.
5. With your iPhone still connected, open blackra1n and click “Make it rain”.
6. Manually power cycle your iPhone 3G if it doesn’t restart automatically for you.

That’s all there is to it.  I know these steps work because it’s exactly what I did on my iPhone.  The last part of the uninstall is pretty hairy since I wasn’t able to close iTunes without unplugging my phone.  Also, when I ran blackra1n, my phone never rebooted on it’s own.  The screen went black and I just unplugged the iPhone and forced a restart.  When my iPhone booted up, I was back on 3.1.3.

I hope this helps somebody out because iOS4 on an iPhone 3G is horrible.

Below is a recap of our setlist, and notes about the technology we presented on. When you see mentions of a Flash movie, these are not run as standalone SWF files. They are actually played by our Flex based Compilers Live Player. This application runs on our guitarist Jun Heider’s laptop, and the entire app is controlled over MIDI, via a Behringer FCB1010 Foot Controller, MMJ, and MERAPI.

Intro Song

For the first song of our set we decided to use a funny and informative Flash movie to give the audience a hint at what they’re about to see. For the June RMAUG show, this movie was updated to include spoken thank you slides for the companies that make our technology, and special shout outs to all the people who help us put on a great show.

Don't point and click to your files, just type their name

If you’re unfamiliar with this, it’s a File Open dialog that let’s you type the name of the file you’re looking for, instead of requiring you to point and click your way to the file. This is one of the few features I still can’t believe Visual Studio doesn’t have built in. Now I’ve had other MS experts show me similar “quick find” features of Visual Studio, but it’s still not as easy as Ctrl+Shift+R > type the filename.

When I was using Visual Studio 2008 I came across the Sonic File Finder plugin and I was hooked.  Then I upgraded to Visual Studio 2010 and my plugin went away.  Today I solved my quick open plugin issue by browsing the Visual Studio Gallery and installing Quick Open File.  This quick open plugin does exactly what Eclipse’ Open Resource does, and it’s a good bit simpler than Sonic File Finder.  Now that I’ve got the plugin installed, the next step is to configure Visual Studio to open this plugin when I hit the Ctrl + Shirt + R keyboard combination.

Add Ctrl+Shift+R to Visual Studio

1. Fire up Visual Studio
2. Click Tools > Options > Environment > Keyboard
3. You should now be at the window for assigning keyboard shortcuts

   

4. Type “Quick” into the Show commands containing box
5. Click inside the “Press shortcut keys” box, and then press Ctrl + Shift + R on your keyboard
6. Assuming you’ve set this to Global, you are now good to go.

**NOTE : When assigning a keyboard shortcut in Visual Studio, you want to make sure your new shortcut isn’t already assigned to a different command.  If this is the case, you should remove your shortcut assignment from the other command before assigning to your new command.  This dialog will show you what is already assigned to a keyboard combination like so.

Assuming you made it this far, pressing Ctrl + Shift + R in Visual Studio should now show you this Quick File Open dialog.

There you go, quick open in Eclipse and Visual Studio!

The base concept is using your knowledge of SQL’s UNION operator to add a temp value to the beginning of a list of data from a sql query.  In the past I’ve done this countless times via code, and recently I didn’t have the time to do this, so I updated the query to a UNION, and I was good to go.

Now I’m not selling this as a ‘best practice’, but I do consider this one more reason why it’s good to know SQL.

Problem : Using a SQLDataSource to populate a DropDown component, how do you inject a spacer value in position 0? EX : “- select value -”

Solution : Inject your spacer value in your SelectCommand via sql’s UNION operator

ComboBox

<asp:DropDownList runat="server" ID="meter_manufacturer_dd" DataSourceID="sql_meterManufacturer" DataTextField="Manufacturer" />

DataSource

<asp:SqlDataSource runat="server" ID="sql_meterManufacturer"
    SelectCommand="
    SELECT '- Choose Manufacturer -' as Manufacturer
    UNION
    SELECT DISTINCT Manufacturer FROM Smart_Meter_DEF"
    />

What this solution gets you.

1. Your spacer value shows up in position 0 ( because the first character is – and not alphanumeric )

2. Auto ViewState caching ( EG : going straight .NET solution, .NET handles persisting your dropdown selection between postbacks )

* in this sample, the connectionString for the SqlDataSource is set in code.

I had this need on an app recently and built a little dynamic sql action that does just this.  The example below however, uses the the DatabaseLog table in the AdventureWorks sample database to return a count of Events logged for each Schema.  Before jumping into the PIVOT, here’s a simple query that gives you the same information, all Schemas, Events, and Event counts.

SELECT      [Schema], [Event], COUNT( [Event] ) AS 'event_count'
FROM        DatabaseLog
GROUP BY    [Schema], [Event]
ORDER BY    [Schema]

Running this query should give you a long result looking something like this.

While this query returns the same information to you, I don’t like this format as much as using PIVOT.  This query result is long and requires a bit of manipulation to get into a readable format.

Now let’s have a look at retrieving the same information using the PIVOT function.

USE AdventureWorks

-- populate temp Event table
SELECT DISTINCT [Event] as 'Event'
INTO	#events
FROM	DatabaseLog

-- this var will hold a comma delimited list of [Event]
DECLARE	@eventList nvarchar(max)

-- create a flattened [Event], list for the PIVOT statement
SELECT	@eventList = COALESCE( @eventList + ', ', '') + CAST( QUOTENAME( [Event] ) AS VARCHAR(1000) )
FROM	#events
ORDER BY [Event]

-- drop table var since our data now lives in @eventList
DROP TABLE #events

-- this var will hold the dynamic PIVOT sql
DECLARE @pvt_sql nvarchar(max)

-- NOTE : we're using dynamic sql here because PIVOT
-- does not support sub SELECT in the 'FOR Event IN ( )'
-- part of the query.
-- If we don't use dynamic SQL here, the PIVOT function
-- requires you to hard code each 'Event'
-- Using SELECT * here so the [Event] columns are auto included
SET @pvt_sql = 'SELECT	*
                FROM
                (
                    SELECT	[Event], [Schema]
                    FROM	DatabaseLog
                ) AS data
                PIVOT
                (
                    COUNT( Event )
                    FOR Event IN
                    ( ' + @eventList + ' )
                ) AS pvt'

-- run the query
EXEC sp_executesql @pvt_sql

Assuming you have the AdventureWorks database installed on your server, running this sql should give you a result looking something like this.

Show all Schemas and count of each Event type

This query result was truncated to fit in this post, but just know the query above creates a column for every Event in the Databaselog table.

A quick explanation of what’s happening in this sql

1. First you fill a table variable ( #events ) with all Events from DatabaseLog
2. Next create a comma delimited list of the Events inside of the table variable
3. Drop the table variable now that we’ve got our delimited list of Events
4. Build the PIVOT statement as a string so you can inject the Events list
5. Fire the dynamic SQL via EXEC

Dynamic SQL is something that comes in handy from time to time, but I do my best to only use it if I absolutely have to.  In this case we’re using it because the PIVOT function does not allow sub SELECT statements.  This is also why we create a specially formatted delimited list of Events prior to building the dynamic sql.

So there you have it, one example of using PIVOT against a varchar column instead of an integer column.  Also, this is a pretty good example of a dynamic PIVOT since it’s pretty simple.  I hope this makes sense, and if you have any suggestions of better techniques, I’d love to hear it.

The paths, they match!

However, I typically launch my batch files from a toolbar on my taskbar that points to the same folder.  The batch file still works, but the path shown in the command window is weird.  I have no idea how an Adobe Version Cue path could get injected, but it does.

Weird paths

To capture both shots of the command window I had to hit Pause.  These aren’t faked, they’re just completely random.

DataBinding: ‘MyApp.vo.customVO’ does not contain a property with the name ‘Name’

I was stumped because my custom VO class did in fact have a public property called Name.  After many trials and tribulations I figured out that .NET didn’t like how I structured my custom class.

Here is what my original custom class looked like.

namespace MyApp.vo
{
    public class customVO
    {
        public Int32 id  = 0;
        public DateTime time  = new DateTime();
        public string Name  = string.Empty;
        public string DeviceType  = string.Empty;
        public string ObjectIDs  = string.Empty;
    }
}

Luckily I have JetBrains ReSharper installed, and it suggested using C#’s Auto-Implemented properties. This is the one thing I hadn’t thought about trying, and it ended up being the fix! My new custom VO class now looks like this.

namespace MyApp.vo
{
    public class customVO
    {
        public Int32 id { get; set; }
        public DateTime time { get; set; }
        public string DeviceType { get; set; }
        public string ObjectIDs { get; set; }
        public string Name { get; set; }
    }
}

So if you find yourself running into this error while trying to DataBind a collection of custom classes to a ListBox or similar control, have a look at your custom class and see if you can convert it over to using auto-implement properties as well.

Now I’m not suggesting this is the only way to DataBind a List of custom classes to a ListBox, but it solved my problem and let me do direct databinding from my service call without having to do any pre-processing on my list.

Hope this helps someone else.
