The point of this, this application is enable to retrieve more detail image / depth data than simply retrieving from OpenNI.
So you can confirm my black eyes in this video like radiohead music video “House of Cards”.
Actually I used their source code.

If you are interested in source code, please write comment.

By the way, I developed desktop application by Adobe AIR though iMIDICon is iPad application..

Today I announce you to sale iMIDICon as $0.99 until 1/5/2011.
iMIDICon is an iPad application as MIDI controller.Please try this if you are interested in my application.

caution:
It takes time to refresh price of iMIDICon. So after you check the price, please buy iMIDICon.

Finally, my first iOS application “iMIDICon” was released!
This application is a MIDIController on iPad.

This application makes your iPad change to MIDI Controller.
I use this application because I’m a VJ.

If you are interested in my app, please buy it.

Now I develop iPad app that shows my contents to external display.
I had many problems to implement it, so I post this article.
In addition, it is so hard to debug about external displaying because iPad cannot connect one plug.

Basically, the way to implement to show contents to external display:
1. get available screens to use [UIScreen screens] as NSArray.
2. get favorite UIScreenMode in 1.
3. get UIScreen.
4. set 2. to retrieved UIScreen object.
5. create contents that want to show to external display.
6. create UIWindow instance.
7. do [uiwindow addSubView:content];
8. set uiwindow.screen = 3.(UIScreen instance.)
9. set UIWindow basic configuration.

That’s all. Once you test it, it is easy.

Here is sample code:
——————————————

// log message displayed in external monitor.
NSMutableString *str = [[NSMutableString alloc] init];
int screenCount = [[UIScreen screens] count];

// used screen mode
UIScreenMode *current = nil;

// checking each screen information
for(int i = 0; i < screenCount; i++)
{
int modelen = [[[[UIScreen screens] objectAtIndex:i] availableModes] count];

// checking each screen mode in screen.
for (int j = 0; j < modelen; j++)
{
// getting screen mode
UIScreenMode *curMode = [[[[UIScreen screens] objectAtIndex:i] availableModes]
objectAtIndex:j];

// get information of screen.
NSString *sstr = [NSString stringWithFormat:@"screen:%i, mode:%i, w:%f, h:%f,
ratio:%f ---", i, j, current.size.width, current.size.height,
current.pixelAspectRatio];

[str appendString:sstr];

// if curMode.size.width is larger than current, change current reference
if(curMode.size.width > current.size.width){
current = curMode;
}
}
}

// screen object
UIScreen *another = [[UIScreen screens] objectAtIndex:1];
another.currentMode = current;
CGSize size = current.size;
uvc = [[UIViewController alloc] init];

// create new window.
UIWindow *window = [[UIWindow alloc] initWithFrame:CGRectMake(
0.0f,
0.0f,
size.width,
size.height
)];

UITextView *tv = [[UITextView alloc] initWithFrame:CGRectMake(
0.0f, 0.0f, 800.0f, 800.0f)
];
[uvc.view addSubview:tv];
tv.text = str;

[tv release];

[window addSubview:uvc.view];
window.screen = another;

[window makeKeyAndVisible];
[window setHidden:NO];

If you have any question about this, please ask me.

I created application that manage my task because I am liable to forget my task.
I wrote C# because my computer in my company is Windows Vista and I want to detect System event.

This article is my memo about ItemsSource property of ListBox control.
All I want to do is to binding the properties of my entity class to DataTemplate in ListBox.

a part of Window1.xaml
ListBox：

<ListBox x:Name="dataList" ItemTemplate="{StaticResource listTemplate}"/>

This is the definition DataTemplate (”TodoEntity” is the entity class I wrote.) :

<DataTemplate x:Key="listTemplate" DataType="{x:Type local:TodoEntity}">
            <Grid ToolTip="{Binding Path=DescriptionValue}">
                <Grid.ColumnDefinitions>
                    <ColumnDefinition Width="*"/>
                    <ColumnDefinition Width="*"/>
                </Grid.ColumnDefinitions>
                <StackPanel Orientation="Horizontal" Grid.Column="0">
                   <TextBlock Text="Subject"/>
                   <TextBlock x:Name="subject_tb" Text="{Binding Path=SubjectValue}" />
                </StackPanel>
                <StackPanel Margin="10,0,0,0" Orientation="Horizontal" Grid.Column="1">
                    <TextBlock Text="Description:"/>
                    <TextBlock Text="{Binding Path=DescriptionValue}"/>
                </StackPanel>

            </Grid>
        </DataTemplate>

And, this is the entity class: TodoEntity

/// <summary>
        /// This is the flag that this task is done.
        /// 1: done
        /// 0: unfinished
        /// </summary>
        public int isFinished;
        /// <summary>
        /// subject
        /// </summary>
        public string subject;
        /// <summary>
        /// description
        /// </summary>
        public string description;
        /// <summary>
        /// register time
        /// </summary>
        public DateTime registerDateTime;

        #region Accessor method. Cannot display subject property when binding subject directly. However It is good work when using accessor method below.

        public string SubjectValue
        {
            get
            {
                return subject;
            }
            set
            {
                subject = value;
            }
        }
        public string DescriptionValue
        {
            get
            {
                return description;
            }
            set
            {
                description = value;
            }
        }
        #endregion

I wanted to bind subject property of TodoEntity class, so I wrote {Binding Path=subject}, instead of {Binding Path=SubjectValue}, but nothing displayed.
I don’t know why can display data when using accessor method (SubjectValue, DescriptionValue).

I don’t know, but data is displayed correctly…..

You can free to use this sample, though I wrote copyright.

About code:

MutipartPostHelper: This is the helper class that can upload files by POST method.

Usage : (please see HTTPPostSample2ViewController.m)

1. Set URL
2. generate string data (need both arrays for key and value)
3. generate binary data
4. add string data to MultipartPostHelper instance
5. add binary data to MultipartPostHelper instance
6. send by using “send” method

When I use FMDatabase library in development of iPhone application, I use the library like this:

When I want to query

“select” : executeQuery

other queries( delete, update, create table, insert, and so on.) : executeUpdate

My application can’t operate because I had mistake this…

So I want to set basic authentication in my developing environment.

However, I had a trouble about this.

Here is my memo:

• create “.htaccess” file

1.  URLLoader() : an object to send
2.  URLRequest() : an object to configure the method to send and specify url to send
3.  URLVariables() : an object to set datum to send

It is OK, isn’t it?

I write sending only in this article.

So, I set several datum to want to send in URLVariable object.

The sample is here:

// setup datum to want to send
var urlvariables:URLVariables = new URLVariables();

urlvariables.data1 = variable1;
urlvariables.data2 = variable2;
.
.
.

// set URL to send, Send
var urlrequest:URLRequest = new URLRequest();
urlrequest.url =

that’s all. Sorry, this is my memo.
