How to scrape the screen data of an external page.

I am trying to scrape the data off of an external webpage using Web Dynpro for ABAP.  Basically, I want the html code of that page in a string so I can parse it later.
Does anyone know how to do this?

  • How to remain the screen data after poping up the message.?

    Hi Experts,
    Case:
    Whe User is creating a sales order, suppose in the screen he had given the sales organization, divison, channel etc.
    Now i have to modify the exit to validate some condition by taking all the data. For ex. loading date, divison etc.
    If that valdiation failed i have to popup a message to user and
    when user clcik the ok, he should be at that screen and  be able to modify the things to validate again.
    Now problem i am facing is, when i am displaying a popup
    message and after clicking ok from user, control of the  is not going back to the last screen with all the data input by the user.
    Please help.

    Hi,
    Suppose you are using a screen 1000 for intaking all these inputs.
    In its PAI put the fields you require within CHAIN....ENDCHAIN.
    Example:
    CHAIN.
    field salesorder module check_salesorder ON INPUT.
    ENDCHAIN.
    Within the module check_salesorder call a subroutine check_salesorder.
    Within subroutine check_salesorder, call the standard SAP function Module POPUP_TO_CONFIRM_STEP.
    This way you can have a popup and stay in the same screen.

  • How to get the current date using HTMLB JSP page

    Hi All, I developed an iview with several fields using PDK, I would like to know how can I include for a date field a dynamic value witch in this case is the current date.
    <hbj:inputField
    id="Date"
    type="date"
    maxlength="10"
    showHelp="TRUE"
    required="TRUE"
    value="???"
    />
    Thanks in advance
    Alexis

    Hi Alexis ,
    u can use the setDate("3.12.2003") function to set date for this input field.
    u just change the id = Date , because in jave we have Date class. rename it to another name..
    suppose id = systemDate
    <%
    Format formater = new SimpleDateFormat("dd.MM.yyyy");
    Date syDatum = new Date();
    %>
    then
    put
        systemDate.setDate(formater.format(syDatum));
    this will set the date .....

  • How can I capture the screen data sheet from netwrork analyzer?

    Hi All!
    Could you help help me this! I want to capture the screen data from network analyzer, and save it to my PC. How can I do that with LabVIEW 8.0?

    Hello,
    Do you know if the 8722A is similar to the 8722B or C model?  We have a LabVIEW driver for those, but the A model is not listed.  Click here to go to the driver download site.  Even though your instrument may not be on the list, the driver may still work with your instrument, so I recommend downloading and installing it to see if you get anything. 
    When you want to capture the whole screen, what exactly do you mean?  Do you want to capture an actual screenshot of the display of the analyzer or do you just want to capture all the data in digital format and send it into LabVIEW? Do you need an excel type file?  Are you seeing the display on the instrument itself or a user interface panel program on your computer?  If on your computer, is it LabVIEW or a different software program?  I am sorry, but I am not familiar with your instrument or how it works, but hopefully we can get this figured out for you!

  • How to reload the screen when changing languages in JavaFX 2?

    I'm beginner with javaFX and i need to change language of the screen. but i have no idea how to reload the screen when the language was changed. The application have a button where have the language available. I want just refresh screen when the user change language.
    Here is the start method to show the stage.
        @Override
        public void start(Stage stage) throws Exception
            this.stage = stage;
            Locale locale = Locale.getDefault();
            ResourceBundle rb = ResourceBundle.getBundle("resources/Label",locale);
            loader = new FXMLLoader(getClass().getResource("FXMLDocument.fxml"),rb);
            root = (Parent)loader.load();
            FXMLDocumentController controller = (FXMLDocumentController) loader.getController();
            controller.setMain(this);
            scene = new Scene(root);
            stage.setScene(scene);
            stage.show();
    here is the function to change the language(in the same class with start function),the rb is the new ResourceBundle:
        public void refresh(ResourceBundle rb)
              //change the language here
    1. I don't want to use the resourceBundle to get value in resource file and set label in scene one by one.like following:
    this.btnLabel.setText(rb.getString(key.test));
    2. I don't want to reload the scene,like following:
        public void refresh(ResourceBundle rb)
             try
                loader = new FXMLLoader(getClass().getResource("FXMLDocument.fxml"),rb);
                root = (Parent)loader.load();
                scene.setRoot(root);
                FXMLDocumentController controller = (FXMLDocumentController) loader.getController();
                controller.setMain(this);
            catch(Exception err)
                err.printStackTrace();
    So do we have a solution to just set the resourceBundle and reload the scene easier?
    Thanks and best regards!

    Your option 2 (reload the FXML for the scene using the new resource bundle as a parameter), is the way this would normally be done and what I would recommend.
    Failing that, you could use option 1 of individually resetting the label text of labeled items (I don't really recommend this).
    Why don't you want to use option 2?
    Perhaps it is because there is some internal state of the UI which differs from the initial state when the the UI is first loaded (e.g. user has typed text in a text field and you want to preserve that).  If that's the case you will need to either go with your option 1 of individually resetting the label text of labeled items, or implement something which preserves the UI state and user data by saving it in memory or to disk, reloading the UI via the FXMLLoader (essentially your option 2), then restoring the UI state and user data to what it was before the language change.  Preserving and restoring the modified state seems complicated to me if you have a lot of state, so I wouldn't really advise this approach unless you really needed it.

    1. Create a  New Formula in Key Figures structure
    2. Give tech name and description and Select "New variable" option
    3. Next screen will launch Variable Wizard -> create a new variable with replacement path as processing type
    4. in next screene  select the date characteristic that represents the first date to use in the calculation (From Date)
    5. In the next  screen select Key in the Replace Variable with field. Leave all the other options as they are
    6. In the next Currencies and Units screen select Date as the Dimension ID.
    6. Save variable
    repeate the Above steps to create another variable (To Date)
    and now you can use these two new replacement path variables in your new formula.

  • How to call the screen in methods could u please explain

    hi,
    how to call the screen in methods could u please explain clearly with example

    HI ,
    CALL SCREEN - Call a screen
    Basic form
    CALL SCREEN scr.
    Addition:
    ... STARTING AT x1 y1 ... ENDING AT x2 y2
    Effect
    Calls the screen scr; scr is the number of a screen of the main program. You use SET SCREEN 0. or LEAVE SCREEN. to define the return from the CALL screen.
    Note
    Please consult Data Area and Modularization Unit Organization documentation as well.
    Addition
    ... STARTING AT x1 y1  ENDING AT x2 y2
    Effect
    The coordinates x1, y1 (start column and start line in the window) and x2, y2 (end column and end line in the window) define the size and position of the CALL screen ("top left - bottom right"). Besides these coordinates, you can also see the contents of the primary window, but cannot perform any action there.
    Note
    If "ENDING AT ..." is not specified, suitable values are substituted for x2 and y2, taking into account the size of the called screen.
    Exceptions
    Non-Catchable Exceptions
    Cause: No further screen level (call screen); the maximum number of nested screen levels is restricted to 50 at present.
    Runtime Error: DYNP_TOO_MANY_CALL_SCREENS

  • How to access the Custom Data type variable given in Expression edit control To and From LabVIEW

    Hello, I would like to know how to access the custom data type variable given in the Espression Edit Control from LabVIEW and vice-versa
    Say, the FileGlobals.Reference_Handle (Custom Data Type Variable) contains the
    VISA I/O session (Which in turn contains VISA_DeviceName: String, Session: Number),
    Channel1: Number and
    Channel2: Number
    I am expecting the user to give FileGlobals.Reference_Handle as the input at the ExpressionEdit Control in the edit screen of the VI Call.
    I would like to know how to get the values of this custom data type to LabVIEW?
    Say, if I have the Cluster in LabVIEW like VISA I/O session (Deive Name and Session Number), Channel1 and Channel2
    how do i need to set this cluster to the Custom Data type variable in TestStand?
    Thanks and Regards
    Prakash 

    Hi,
    TestStand to LabVIEW: i didnt understand what you r trying to achieve. But if you are using references, Use Property nodes and Invoke nodes to achieve what you want in LabVIEW.
     LabVIEW to TestStand: check the image below: You need to click the button next to 'container'. I have used a cluster output in the VI.
    Hope this helps

  • How to get  the actual data in ALV report

    I am doing some upgradation work   in that i am using Submit  & And return and  also i am using some function modules like LIST FROM MEMORY , LIST TO TXT wnd WRITE LIST , it gives output in normal list format , But i need to print in ALV report .
    With the use of set table for 1st display i got the  ALV report   but not with actual data, (some junk value is showing) , So can any 1 suggest me how to get  the  actual data in ALV report, With the use of  Any Function Module or with Coding,
    with regards,

    Hi Saravana
    I am sure you must be getting the values in tables of table parameters from every FM.
    consolidate the values from tables of all FMs in one table and built ALV for that table only.
    I hope this way you can show the actual data in ALV.
    thanks
