  • How can I get my web cam to work in Adobe Connect ?

    This is actually an end user's question that I am having trouble answering to...
    We use Adobe Connect to give online language classes, the end user is one of the students.
    I cannot find the right Support answer to give him.
    Problem:
    My camera does not work when I connect to Adobe's rooms but camera works fine with other software.
    Even though I suspected my old camera was working fine, yesterday I went ahead and bought a new camera. 
    I thought perhaps my webcam software may have been a problem, so I bought a different type camera with different software. 
    Even after removing all the old software, same result:  
    I surmised the problem might be caused by my firewall and security software, so once I tried changing the permissions for Adobe, and my Webcam, but that didn’t work.   
    Another time, I restarted my computer right before class and then turned off my firewall completely so there would be no interference but to no avail. I’m totally perplexed.  
    Isn’t there anyone else experiencing a similar problem?   Has anyone else found a solution? 
    I run Windows Vista with McAfee Internet Security Software.  I always reboot the computer before class and open no other programs other than Google Chrome. 
    I now have a brand new Microsoft LifeCam Cinema Camera with LifeCam 3.5 Webcam Software. 
    I test my camera before going online.  It always works fine.   Then I shut down the camera program and login into class.   
    When I “connect webcam” in the room, the light on my camera comes on (suggesting that it is ON), but only a black image is transmitted to the room.

    Check to see if you have Google Voice installed. If so, remove it and see
    if your problem vanishes. If not Google Voice, check to see if you have
    any other communications software which interacts with your cam and
    disable it. This was the problem I had with a similar problem on a Mac.

    Thanks a lot Heyward for the swift reply !
    I sent the advice out to the end user, but unfortunately this wasn't the
    solution.
    His reply is below :-
    The default resolution of my new camera is already set at 640x360, but I
    went ahead and tried several lower resolutions (e.g. 424x240; 320x240; and
    160x120) but none worked in the room - camera still showed up as black
    blank screen.  Also, as far as I can tell, I don’t have the option of
    adjusting the frame rate.
    I started playing around with my Internet Security Settings to see if they
    might be playing a role. So far, all to no avail.
    Hmm...quite a tricky one - webcams always are - maybe if he can find a way
    to adjust the frame rate (?).
    He's going to fiddle about with the settings a bit more and see if
    something does the trick.
    If anyone has had a similar problem and found an ingenious solution,
    please jot on a note on this thread.

    How to write code for page up and page down buttons on alv screen?

    Poonam,
    On doing the screen debugging it took me over to    Include LSTXWFCC ,kindly check the below code.
    module cc_display.
      fcode = sy-ucomm(4).
      case sy-ucomm(4).
        when 'P--'.
          perform cc_firstpage.
        when 'P-'.
          perform cc_prevpage.
        when 'P+'.
          perform cc_nextpage.
        when 'P++'.
          perform cc_lastpage.
        when 'EX--'.
          perform cc_firstcopy.
        when 'EX-'.
          perform cc_prevcopy.
        when 'EX+'.
          perform cc_nextcopy.
        when 'EX++'.
          perform cc_lastcopy.
    I guess it can give you some lead.

  • How to write program for handling  script ?

    In script i have 2 pages.
    In first page i have constant windows and variable windows.
    In second page i have main window.
    How to write program for this?

    Hi
    You need to write a driver program. You need to use open form, then write_form to write data into various windows and then close_form to close.
    As you don't want main window in the first page first try out just by having the window in the second page; i guess system will take care of it. As all other windows filled and if u start writing data in the main it'll go for next page.
    If doesn't work have the window on the first page with the least hight and write a command
    IF &SYST-PAGE& EQ 1
        NEXT-PAGE.
    ENDIF.
    Then in the second page you can have the main window hight as per your requirement.
    Here is an example
    (1) Get customer data
      TABLES: scustom, sbook, spfli.
      DATA: bookings like sbook...
      select * from...
    (2) Open form
      CALL FUNCTION 'OPEN_FORM'
        EXPORTING
          DEVICE = 'PRINTER'
          FORM = 'S_EXAMPLE_1'
          DIALOG = 'X'
        EXCEPTIONS
          others = 1
    (3) Print table heading
      CALL FUNCTION 'WRITE_FORM'
        EXPORTING
          ELEMENT = 'HEADING'
          TYPE = 'TOP'
          WINDOW = 'MAIN'
          FUNCTION = 'SET'
    (4) Print customer bookings
      LOOP AT bookings WHERE
        CALL FUNCTION 'WRITE_FORM'
          EXPORTING
            ELEMENT = 'BOOKING'
            TYPE = 'BODY'
            WINDOW = 'MAIN'
      ENDLOOP
    (5) Close form
      CALL FUNCTION 'CLOSE_FORM'
