  • Can any one tell me when i use adobe flash media encoder how can i see my live vidoes on flash media

    can any one tell me when i use adobe flash media encoder how can i see my live vidoes on flash media server . thnx

    Flash Player version 10.1.102.64 is the last version available to PPC Mac users. However, this Flash version won't work for many videos on Facebook, YouTube and other sites. Adobe's latest version, 10.2.x or later, is only for Intel Macs. Adobe will not provide a newer Flash version for PPC Macs.
    The message requesting that you download Adobe Flash Player takes you to Flash Player requiring an Intel processor. Doesn't work on a PowerPC processor. I found a hack, installed it & it works with Firefox, TenFourFox & Safari.
    Download this http://www.steelbin.com/FPforFBPPC.zip to your desktop, unzip it, and replace the current Flash Player plug-in which is in your main/Library/Internet Plug-Ins folder, (not the user Library). Save the old one just in case this one doesn't work.

    Table Buffer:Table Buffer is a  place on the RAM where we store the whole table temperorly.Single Buffer:It is one type of buffering techniques through which we can store single record of a table on RAM temperorly. If more details are present ...
    This r some think to buffer the data in application server. Buffer not allowed will buffer data in AS.  Data will be fetched directly from Database server. Buffer switched on means it buffers data in AP means data is fetched from application Server. Buffer switched allowed but switched off.  Full buffer to store the table in AP. Generic buffer - It is a comparison of fields i.e. data retired by the matching record.

    hi, i want to control my vi from multiple systems using ethernet options can any body tell me how to do that?  thans in advance

    There are multiple ways of doing this. Here are some of them..
    The Web Publishing tool allows you to publish the front panel and you can control the front panel remotely.http://www.ni.com/white-paper/2911/en/
    The TCP/IP socket can allow you to pass codes "strings" to another computer. Lookup the server client example.

    A manufacturer part profile contains indicators and control parameters, which define the conditions for using (inventory-managed or non-inventory-managed) manufacturer parts in the procurement process.
    The manufacturer part profile specifies how manufacturer parts (MPN materials) can be used in the procurement process.
    The manufacturer part profile is assigned to the master record for a firm's own inventory-managed material.
    Among other things, it determines whether:
    u2022     The MPN material or the inventory-managed material is to be entered in a purchase order
    u2022     Info records can be created for the MPN material or the firm's own material
    u2022     The MPN material can be changed during the procurement process

    Hi Praveen,
    Event container is the container which stores the values of the BO attaribures which get assigned to that instance of the BO.
    If you go to SWO1 transaction and check the BO for which the event is triggered, you would see all the possible attributes than can be assigned.
    To pass the values of the BO event container to the workflow, you need to maintain the necessary binding between the BO event container and the workflow container. This can be done in the 'Basic Data', Start Events tab. If you click on automatic binding, the system would prompt for a default binding. You could opt to use that or create your own binding. Make sure that the datatypes match.
    After mapping the event container to workflow container, you can check in the workflow log for the values passed to the workflow container. If you like to directly check the values stored in the event container, go to SWO1 and simulate an instance of the BO. You can then check the values there.
    Hope this helps!
    Regards,
    Saumya

  • Can any body tell me, can we attach field exits to Njoy trnsactions in 4.7

    Hi,
      can any body tell me how to attach field exits to the enjoy transactions in 4.7.
    I was not been able to attch the field exits to "Account assignement catagory" in trnasaction ME51N(Purchase requisition creation) using the program "RSMODPRF".
    Please suggest.
    Best Regards
    Ramanjaneya Reddy

    But hey! Your in 4.7, use BADIs!
    Goto transaction SE18, search and you will find some stuff like ME_PROCESS_REQ. There are several dozens for purchasing, so go for the new technics.
    By the way, I'm not sure if workaround is still possible in 4.7.
    Implementation will be done with SE19.

    I have installed the jsms engine and when i try to connect to the mobile device ,the jsms server is giving
    the following error.

    The best place to ask your question is at the JSMS website, forum or mailing list since this is no error that directly comes from a class belonging to the core Java classes.

    Can any body tell me How to store string array in a array

    YesNot quite sure what question you're answering but here's how to copy an array.// given a String[] strArr
    // pre Java 6
    String[] newStrArr = new String[strArr.length];
    System.arrayCopy(strArr, 0, newStrArr, 0, strArr.length);
    // post Java 6
    String[] newStrArr = Arrays.copyOf(strArr, strArr.length);Edit:
    Or in fact use clone() as mark pointed out.

  • Can any body tell me how to make changes in the print layout of Fb03.

    hi,
    Can any body tell me how to make changes in the print layout of Fb03.
    I want to add comapny address on the layout.
    Regards
    Mave

    If you mean the correspondence, you have to change the configuration in Financial Accounting -> AR and AP -> Business Transactions -> Outgoing Invoices -> Carry Out abd Check Settings for Correspondence. There, you need to assign your custom Program or Layout for the Correspondence Type (like SAP19) and Program.
    If you mean the display layout in transaction FB03, You can change a few settings, mainly with BKPF and BSEG fields. I don't think you can add company address, though.
    Good luck,
