How to bind the value of slider from C# code in windows phone 8.1..?

Hi, I want to bind a custom seek bar to the position of media element.
I think from XAML we can achieve it by 
     Value="{Binding ElementName=mediaElement, Path=Position, Mode=TwoWay, Converter={StaticResource FormatConverter}}"
where FormatConverter is a converter class written to convert mediaElement object to slider value during binding.
But I am creating the media element from code, so I want to write C# code to achieve the above. How to do it..?

You can create the same binding in C# by instantiating a
Binding class and setting its Path, Source, etc. properties. See the remarks in the Binding class docs and
Creating bindings in code in the
Data binding with XAML docs.
That said, the Position updates significantly more frequently than you want to update the seek bar, so you may want to use polling rather than binding for this specific use (especially since you're already in the code behind rather than in the Xaml).

  • How to get the value of column from previous row to current row?

    Hi All,
    I am facing a critical problem in SQL query (for reporting purpose (COGNOS)). please reply to my query.
    REQUIREMENT: i want to retrive value of a column (this is not a table column, this will be calculated based expression) from previous row to current row.
    EXAMPLE:
    TABLE NAME: i have to join multiple tables. so, i am not mentioning table names here.
    DISPLAY COLUMNS in the report: item, loc, sku, beginval (not table column), endval (not table column, this will calculated based on some expressions), etc. Here, first time the value of BEGINVAL will be taken from some x column name of x table. ENDVAL will calculated based on the expression. For the next row onwards, BEGINVAL will become the value of ENDVAL and the value of ENDVAL will be calculated based on the expression and this expression uses the value of BEGINVAL.
    my report will look like below.
    ITEM LOC SKU BEGINVAL ENDVAL
    1 HYD 1-HYD 10 10+1+2 (13)
    2 HYD 2-HYD 13 13+1+2 (16)
    3 SEC 3-SEC 16 16+1+2 (19)
    4 SEC 4-SEC 19 19+1+2 (22)
    etc....
    in the above output, BEGINVAL and ENDVAL columns are not part of any table. they are alias column names.if you observe intially BEGINVAL will be assigned to some value, but from subsequent rows, BEGINVAL will become the ENDVAL of previous row.
    Please help me on how to write this query?

    Hi,
    whenever you click on Excel download option select spreadsheet instead of unconverted
    There is a possibility of download the spool file as txt-file. .
    Use Tranx SP01 - select the spool entry -->"spool request --> forward as text . You will find the file in your SAP work directory as <sid><spool#>.
    or use fm RSPO_DOWNLOAD_SPOOLJOB.

  • How to get the pull path name from a file upload window

    Hello everyone!
    I have encountered the following problem with the following JSP code:
    <form method="post" action="filename.jsp">
    Upload JAVA program:
    <input type=file size=20 name="fname" accept="java">
    <input type=submit value="go">
    </form>
    <%
    String s = "";
    if (request.getParameter("fname") != null)
    s = request.getParameter("fname")
    %>
    The value of s is alway the filename. However I want to get the full path in addition to the filename, so that I can read the file. Does anyone know how to get the pull name of the file?
    thanks a lot in advance,

    Dear Sir,
    thanks a lot for your reply. Please let me explain what I intended to do: I want to upload a file from the local machine and then read the content of the file. Therefore I need to the fullpath of the filename like /var/local/file.java instead of file.java. The latter is what I got.
    The problem I have with your code is that the function like "request.getServerScheme()" is not recognized. Maybe is it because I didn't install servelet package?

    Before learning about LabVIEW, learn about images.  An Image (in LabVIEW) is a "representation of an image", that is, the wire itself doesn't really have a "value", but "points to" a collection of data that can be "imaged" (i.e. looked at as through it were a picture), "manipulated" (for example, extracting a color plane, basically getting the "red channel", an image looking as through it were viewed through a red filter), and possibly returning arrays of numbers representing the intensity of the light at a certain position in the picture.

    Thanks&Regards
    kranthi

    Hi Kranthi,
    Every webdynpro component has a global controller called the component controller which is visible to all other controllers within the component.So whenever you want to share some data in between 2 different views you can just make it a point to use the component controller's context for the same. For your requirement (within your popups view context) you will have have to copy the component controllers context to your view. You then will have to (programmatically) fill this context with your desired data in this popup view. You can then be able to read this context from whichever view you want. I hope that this would have made it clear for you. Am also giving you an [example|http://****************/Tutorials/WebDynproABAP/Modalbox/page1.htm] which you can go through which would give you a perfect understanding of all this. In this example the user has an input field in the main view. The user enters a customer number & presses on a pushbutton. The corresponding sales orders are then displayed in a popup window for the user. The user can then select any sales order & press on a button in the popup. These values would then get copied to the table in the main view.

    Hi,
    How to get the value from databank? and how to set the same value to visual script object?
    thanks,
    ra

    Hi,
    You can use GetDatabankValue(HeaderName, Value) to get the value from databank and SetDataBankValue(HeaderName, Value) to set the value to databank.
    You can refer to the API Reference to see list of associated functions and techniques we can use with related to Data Bank.
    This is the for OFT but if you are using Open Script then you have direct access for getting the databank value but when it comes to setting a value you have to use File operation and write you own methods to do the set operation.

    Hi

    i have field empno in repeated frame and i want to disply first 3 digits in another place in the same report.
    thanks

    How often do you need to display it? It sounds like you might want to base a summary on that formula with a function of first or last. If it's a per page basis, it can be a page level summary. If it's at a higher level repeating frame, then you can create the summary at that level. I'd suggest taking a look at the online help for summaries using the first/last functions.
    Hope that helps,
