can any one send me the link or else please give in writing the operators used in oo abap. like ->, =>, ?= etc etc. please send me them i didnot find them in many sites that i am going through .
thanks and regards

These operators are described in the standard SAP help under ABAP Objects Overview but in particular:
-> is an instance component selector
=> is a static component selector
?= is used for widening casts (casting one object to another)
Thanks,
Pete

  • Regarding adobe form using Webdynpro ABAP

    Hi,
    I am new to webdynpro abap.
    Currently I am working on a scenario where..
    I have a function module which generates the pdf for me based on the vbeln i provide in the first view. The only thing I have to do is  to display the generated pdf on explorer.
    As for as the examples i gone through.....I should provide the existing form name or the interface name. I don't have either of them as the function module is generating the pdf for me.
    Could any one help me on this please....
    Thanks,
    Vijaya.

    Hello Vijaya,
    Please check out the following
    https://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/f0de1eb8-0b98-2910-7996-8a3c2fcf6785
    This is what will work for you with some modifications. Since in your case you are already receiving the PDF from the FM, just set the pdfSource to this value and you should be done.

  • Question regarding the FAN used by WD My Cloud EX2

    Hi, I have a WD My Cloud EX2 product. Using the diagnositic tool in the dashboard I noticed the Disks temperature is 57 C° and the FAN "RPM is to 0"!!!! The temperature The entire case is hot. I attached an image in ITALIAN language that show the situation. The temperature is NORMAL but in my opinion there is something strange. Must the NAS reach a particular temperature to start the FAN? Regards, Angelo

    I had the exact same problem.  My unit would give me a warning about "overheating" but my fan speed was always reported as zero.  I was not able to see the fan spinning during normal operations, but this does not mean it was not spinning when I was not looking.  So I ran the built-in diagnostic routine, no problems were reported and I could see the fan moving during the diagnostic routine.  In normal operations when I would get the overheating message, the fan speed was always reported as zero RPM. It seems to me that the diagnostic routine correctly makes the fan spin so no fan problem is then reported, which gives a person a false sense of no fan problem. Two weeks ago I returned my unit for a refund because of the overheating (zero fan RPM) problem and I also had an ongoing problem with the built-in Amazon S3.  I would like to purchase another EX2 because I think the EX2 is a great value, but at this point I'm concerned about the overheating problem and I see other people are having the exact same problem. Certainly it could be a hardware issue, but I wonder if its a software (firmware) issue.  I have no evidence or information to say either way, but in my situation since the diagnostic routine correctly made the fan spin, it makes me think the issue is more software/firmware.

  • How to upload pdf file to DataBase using webdynpro abap.

    Hi Experts,
    how can i upload a pdf file in document server using webdynpro abap and display the same  pdf file on the view using webdynpro abap.
    Please Provide requried information .
    Thanks & Regards.
    Bhushan.

    NB - the "data" that is returned by these classes is the data as defined in an adobe form - it doesn't return the content of non-form PDF documents.
    The PDF must be an interactive form ( although that doesn't restrict you to using the SAP process for creating the form is my understanding - but I could be wrong. )
    Edit - I was wrong! ONLY PDF documents that have been created by the ADS can have data extracted using these classes. So unless you are using Adobe interactive forms - then you will get no value from this functionality - and if you're using AIF then you're probably just use the standard UI element

  • How to read the excel file using webdynpro abap?

    Hi,
    how to read and modify excel file using webdynpro abap?
    Regards,
    Pavani

    For reading excel file follow the steps :
    1. Use a File upload UI element and bind it with xstring.
    2. Now your excel will be uploaded and stored in Xstring.
    3. Convert Xstring to String data using FM 'HR_KR_XSTRING_TO_STRING'.
    4. Now split the string at new line so as to make an internal table .
      Ex . SPLIT l_string  AT cl_abap_char_utilities=>newline INTO TABLE it_table.
      here it_table is type table of string.
    5.now loop at the internal table and separate the content of this table separated by tab.
      Ex. SPLIT wa_table AT cl_abap_char_utilities=>horizontal_tab INTO TABLE it_new.
    it_new type string_table.
    6. For more info , refer this thread :

  • Populating values in a dropdown field on the interactive form using WD ABAP

    Hi All,
        I want to populate values in a dropdown field( of cardinality 0:n ) on interactive form,The values which i want to populate is from a 'z' table which i have created.I used a select query to fetch the entries but on my interactive form the values are flowing in many rows and not in the drop down.I want all the values to be in the dropdown.The dropdown is not showin even one value under it.I am using webdynpro abap and controls from webdynpro native.Can anyone guide me on this with a step by step procedure.
    Useful suggestions will be rewarded.
    Thanks and Regards,
    Srividya.

    You mean in PFR of controller , ie after user selects a record from LOV window and after its populated back into to the textItem on the main entry form ??
    The value is displayed correctly in the intended textItem which has viewInstance and viewValue attached to it .
    so this is what setup looks like
    Entry form
    Customer Name - lov
    Customer Number(d) - Display Only - Populated by Lovmappings from LOV - mapped to Customer Number attribute on LOV window. It also has viewInstance and ViewAttrib assigned to it .
    Save Action
    At this point of time , i am assuming i already have value in Customer Number(d)since its displayed on the screen,rite ??
    or Do i have to take the value in formValue and then explicitly do a setAttribute to set that value to view object /Customer Number(d)
    hope this helps to understand the scenario
