Beginner: Question of Date validator on live docs example.

Study this example below raise questions, I can not find easy answers for in the livedocs.

1.) why do we need (just a structure object) model? In the date validator I note that we can not put source = "{dateInput.tyext}" "

2.0) the model has an id of "alternateDate", this change makes no difference.

2.1) connected to question 2, how dateValidator uses model because it has no reference to the model.

3.) don't the code below work when you have more than 1 effective date, do you need a model and a separate validator date for each date entry field? This creates a circular problem as there seems to be a link between the dateValidator implicit and model... confused. This means that I have no way to link the models to date validators.

Tire of http://livedocs.Adobe.com/Flex/3/HTML/Help.HTML?content=validators_1.html

    <mx:Model id="alternateDate">
        <dateInfo>
            <date>{dateInput.text}</date>
        </dateInfo>
    </mx:Model>

    <mx:DateValidator id="stringDateV"
        source="{dateInput}" property="text"
        inputFormat="dd/mm/yyyy"
        allowedFormatChars="*#~/"/>

    <mx:Form>
        <mx:FormItem label="Date of Birth (dd/mm/yyyy)">
            <mx:TextInput id="dateInput"/>
        </mx:FormItem>
        <mx:FormItem>
            <mx:Button label="Check Date" click="stringDateV.validate();"/>  
        </mx:FormItem>
    </mx:Form>

I don't see what the model is being used for either - I suspect that it is a mistake in the documentation.

You can not put source = "{dateInput.tyext}", but you can have source "{dateInput}" = and = 'text' property. " The example already done that, IE. He observes the TextInput control directly. If you remove the template in the example should always work.

  • Is there a file where are stored the data pause & rewind live TV in Windows Media Center?

    Is there a file where are stored the data pause & rewind live TV in Windows Media Center? More to the point - how can I save the time shift buffer in WMC?

    I would like to know if it is possible to find the data that Windows Media Center is to store during her watch TV Online. I don't speak data WMC stores by itself to allow the use of the function of pause & rewind live TV, how to find files that you have saved yourself by pressing the Red record button.

    For example, I often live TV playing on the computer in the background while I do something else. Can I see or hear a brief fact/clip/segment of interest that flashes by and I think, ' I wish I had recorded that. " If I go back to the bit I wanted to capture and hit record, it will not capture the part I want, it will start recording from the point, the program has achieved in real time.

    Does anyone know where the actual data of the TV are kept so that I can retrieve these clips that interest me, but were never recorded by me manually? I found the "TempRec" in the folder "Recorded TV" - anyone know how to convert this video (if indeed it is the location where you store temporary data for pause & rewind live TV)?

    If not, is it possible to enable a feature in WMC, which automatically starts the recording of TV channels as soon as you go to them? This way I can record everything, then just cut all the scenes of interest using Movie Maker. If not, are there other Win7 compatible programs that will do this?

    Thank you.

    Apparently, there is a way to achieve the goal.

    A nice gentleman from the Germany wrote dll that create a "time-shift buffer recording" add-in for WindowsMedia Center (for Vista and XP only) which can be found at:

    http://thegreenbutton.com/forums/p/3...83.aspx#162083

    For Windows 7, there would currently be via a 3rd party of program, i.e. PowerCinema 6, which records from any point in the time shift buffer zone - I don't know why Microsoft has not also incorporated this feature into WMC for have other programs third 3rd (including EyeTV for the Mac).

    Unfortunately, suggestions from another forum to change file extensions in .tmp .dvr-ms TempSBE and double-click on the file to read the file of time lag in WMC, does not work in Windows 7 x 64 (the message in this forum has been regarding the Vista x 64), however, I have not tried with other versions of Windows - I would like to know if anyone has had some luck using this method.

    Even if it had worked, I think I would have always preferred the usability and features of a program that does the job for me, like Power Cinema - damage, it could not have been WMC. What do you think?

    Thank you.

  • Using the Dynamic Range name in the Data Validation

    Maybe it's the time of day but I'm being a little dimwit here!

    I use = OFFSET(Data!$G$5,0,0,Vlastrow,1) for the range name Tbl_Names.  When I select F5 to check that the range is highlighted it seems everything is in order.

    On a leaf, I have a Data Validation that uses a list where the Source is = Indirect ($G$ 7).  G7 is the text "Tbl_Names".  The table of Validation and the content of the G7 is on the same sheet.

    Where am I going wrong please?

    Thank you

  • Export to spreadsheet does not show the formatting data Validation rules

    Currently in Hyperion Planning 11.1.2.3, have basic color formatting based on Data Validation rules. However, when you use the option export to a worksheet, the Formatting disappears.

    Understand the connection to Hyperion planning is kept only on Smart View, if she will not apply export on the worksheet?

    Thank you

    Mauricette

    I think that the formatting will be lost during the selection of the option export spreadsheet because it is about a raw format, if you want to format would be preferable to use the Smart View method.

  • LIKE Docs / Adobe live docs content missing?

    Is this just me or is there something missing in AS3 live docs?

    I'm looking for a match, replace and find who I thought were available on the string, otherwise page RegExp.  Ago on RegExp links to Sting.match (), String.replace () and String.search () page, but none of them seem to go in the right place in the channel page.

    Can anyone confirm weather there is a problem with these pages or I'm looking in the wrong place?

    However Adobe screwed up with the doc it seems. String.match () and others are now marked as runtime specific Flash Lite 4 (which is obviously incorrect) and unless you set the doc to view Flash Lite 4 content they are hidden by default JavaScript. To make the worst case the doc does not remember your settings.

  • A question about data binding

    Hi all

    Data binding is easy to use during development. I often set new directive public property, but I find that I can't control the treatment when the property value changes. I learned that there is a propertyChange event when the property is bindable. If a property is set at 29, and I want to be bordered to 30 in the background. How can I achieve this?

    Thank you

    Hi yancaoshi.  I don't know if I understand the question, so if I miss just let me know.

    You can change the value of a property is the value when set using get/set functions.

    private var _value:Number = 0;

    [Bindable]

    public void value(v: Number): void

    {

    _Value = v;

    }

    public function value(): number

    {

    return _value;

    }

    A regular get/set the installer looks something like the code above.  It creates a property named 'value' that can be accessed as if it was declared as a public var.  The difference is that you can add logic to the set function.

    [Bindable]

    public void value (v: Number): void

    {

    stupid logic to raise 29 and 30

    If (v == 29) {}

    _Value = 30

    } else {}

    _Value = v;

    }

    }

    Now, when someone calls the following code, the value of the 'value' property is actually on 30 and anyone "linked" to this property will get the value 30.

    The following documents may be useful:

  • Question about data dba_extents in

    Good evening

    I'm learning to Oracle 11 GR 2 (I'm a beginner). If I log in as SYSTEM and run the following script:
    drop table table123;
    
    create table table123 (t varchar2(10));
    
    select tablespace_name, segment_name from dba_extents where segment_name like 'TABLE%';
    I get (as expected) the following output:
    TABLESPACE_NAME                SEGMENT_NAME
    ------------------------------ ----------------------------------------
    SYSTEM                         TABLE_PRIVILEGE_MAP
    SYSTEM                         TABLE123
    EXAMPLE                        TABLE2
    EXAMPLE                        TABLE1
    always connected as long as SYSTEM I drop from the table using:
    drop table table123;
    Now, I'm going on another session where I am logged in as a different user (but the user has been granted, it's all there) and I do the same thing that I did like SYSTEM (which is running the first script shown above) and the result is different (segment for TABLE123 name is absent) as the output below shows :
    TABLESPACE_NAME                SEGMENT_NAME
    ------------------------------ --------------------
    SYSTEM                         TABLE_PRIVILEGE_MAP
    EXAMPLE                        TABLE2
    EXAMPLE                        TABLE1
    I can't understand why the segment for TABLE123 is still missing, the same script was executed. The only difference is the user, but since this user has as many features as the SYSTEM itself I don't see how the user makes a difference in this case.

    The question is: What happened to TABLE123, why it is not displayed in the second exit?

    Thank you for your help,

    John.

  • Question of Xoom browser with Google Docs

    Why won't the Xoom browser allow me to select and format text in documents in Google Docs (in desktop mode)? I hate the fact that it default to mobile versions.

    I've tested this on the Xoom and the iPad. The iPad can do (although initially, he had some problems, but at least it worked).

    Anyone experience this problem?

    Hi Jim,.

    Yes that helps a little. Just to be sure, I was clear on what I wanted to, I was wondering if it was imperative that a browser was imperative. With respect to documents, if a 3rd party app or browser allows you to manipulate your documents of * me * is unimportant as long as I can do

    In any case, this is what I've tried so far, the stock browser, firefox mobile, Dolphin and skyfire (although I normally do not trust any browser that sends data through its own server first then back out you especially if the document information is sensitive), and they are all mainly display the same behavior... However, I think the fact that there is that no actual pointing device is what is the real problem. With this in mind, I think that, however, any browser would be problematic.

    I also tried it on my iPad and have the same problem as with other browsers, as I do in the mobile Safari browser. Again, I think that the problem is not have a pointing device to see the real highlight of the text on each device.

    I'm still poking around well, but I think that the options are limited at this point Jim. That brings up another point, although several steps into play in 3rd party apps, I have not found it is HORRIBLE when using or Quickoffice or ThinkFree, D2G, when it comes to database formatting... circumspect, (at least for me) it becomes a replacement mobile phone but with a learning curve. I recognize, someone somewhere along the line has a much more intuitive solution for tablets Honeycomb based.
